`ABSTRACT
`
`A vehicle onboard device having characteristics capable of
`being changed communicates with a vehicle to set a char-
`acteristic value to an optimum value. Parametersfor setting
`conditions of an electronic device are called out of an
`E*PROM 14, of the vehicle 10, and are transmitted to a
`technology center 40 via a dealer 20,, and an information
`center 30,. Each dealer 20,, the information center 30,, and
`the technology center 40 accumulate the parameters. The
`technology center 40 can collect the parameters of numerous
`vehicles and characteristic values for electronic control of
`each of the vehicles and can calculate newest and optimum
`parameters. ‘The technology center 40 transmits this newest
`and optimum vehicle information to the vehicle 10,, and
`each vehicle updates the parameters thereof to these newest
`and optimum parameters. Accordingly, the parameters ofthe
`vehicle are set as the newest parameters.

`VEHICLE INFORMATION
`COMMUNICATION DEVICE AND VEHICLE
`INFORMATION COMMUNICATION SYSTEM
`
`TECHNICAL FIELD
`
`invention relates to a vehicle information
`The present
`communication device and a vehicle information commu-
`nication system, and particularly relates to a vehicle infor-
`mation communication device and a vehicle information
`communication system communicating information with a
`vehicle when characteristics of a vehicle onboard device
`which characteristics are capable of being changed are
`changed intentionally by a user, or by geographical factors,
`etc.
`
`BACKGROUND ART
`
`In recent years, a plurality of electronic control units
`(hereinafter, called ECUs) have been mountedin a vehicle.
`This plurality of ECUs are connected to each other by a bus
`so that a local area network (hereinafter, called a LAN) is
`constructed. Data can be communicated between these
`ECUs,
`
`Each of the plurality of ECUs controls the characteristics
`of a vehicle onboard device, Characteristic values for deter-
`mining the characteristics of the vehicle onboard devices
`governed by of each ECU is stored in that ECUs. For
`example, when the vehicle onboard device is a headlamp,
`there is an ECU for controlling a turning-on operation in
`which the headlamp is automatically turned on when the
`vehicle enters a tunnel and is also automatically turned on in
`the evening, etc. In this case, the headlamp is turned on when
`illuminance from an illuminance sensor is less than a
`predetermined value. This automatic turning-on lime, Le.,
`the predeterminedilluminance value can beset as a different
`value in depending on the user and the local area.
`Accordingly,
`there are cases in which a change in the
`predeterminedilluminance value is required.
`A general control system for an automobile is proposed as
`a system capable of changing the contro] parameter program
`of each of the ECUs mounted in such a vehicle in accor-
`dance with a user’s taste (see Japanese Patent Application
`Laid-Open (JP-A) No. 6-219187). In this technique, a char-
`acteristic value for electronic control of the vehicle ts
`obtained by a controller and is sent to a service center and
`the analyzedresults of the characteristic value can be shown
`to a driver. Further, it is possible to maintain and check the
`characteristic value as to whether or not there is a problem
`with the characteristic value proper to the vehicle.
`However, in the conventional system, the characteristic
`values of the individual vehicle can be maintained and
`checked, but characteristics arising from the intentionsof the
`user of from the local geography can be automatically
`reflected. Further, the characteristic values of the individual
`vehicle can be maintained and checked, but characteristics
`arising from the intentions of the user or from the local
`geography cannot be reflected. Furthermore, the character-
`istic values must be finely adjusted for each individual
`vehicle. For example, changes in the characteristics arising
`from the tastes of many users and the characteristic values
`of a particular vehicle are continually changing.
`Accordingly, the user’s intentions, etc. cannot be reflected
`by only simply maintaining and checking the characteristic
`values.
`
`there is a case in which the vehicle onboard
`Further,
`device is replaced with a new deviceor other parts dueto the
`passage of time, device replacement, etc. In this case, the
`
`2
`characteristic values of the ECU governing the new vehicle
`onboard device are different or are unrecorded. Accordingly,
`it
`is necessary to set at least
`the pertinent characteristic
`values every time the vehicle onboard device is replaced
`with a new device or other parts.
`However,
`in the conventional system, the characteristic
`values for electronic control of the vehicle are obtained and
`are maintained and checkedin accordance with the sugges-
`tion of the analyzed results of
`the service center.
`Accordingly,it is necessary to perform a complicated opera-
`tion in which the characteristics of all vehicle onboard
`devices are obtained and the pertinent characteristic values
`in the maintenance and checking are set to suitable values
`every time a vehicle onboard device is replaced with a new
`device or with another part.
`Further, there are now vehicles capable of being equipped
`with controllers such as a telephone system, a navigation
`system, a TV system, etc., and information according to the
`tastes of the main user, ¢.g. the driver, may be recorded to
`each of these controllers. This information may consist of
`personal information such as a rest of telephone numbers,
`address data, a list of recorded locations relating to desti-
`nations of the navigation system, etc. set by an individual.
`This personal
`information is not as widely used as the
`control information, but there is a desire for temporarily and
`reliably holding this personal information.
`However,
`in the conventional system, the characteristic
`value of the individual vehicle can be maintained and
`checked, but no non-general use information such as per-
`sonal information can be held.
`
`In consideration of the above facts, an object of the
`present invention is to provide a vehicle information com-
`munication device and a vehicle information communica-
`tion system capable of communicating with a vehicle to set
`a characteristic value of a vehicle onboard device capable of
`changing the characteristics to their optimum values.
`Further, in addition to the above object, another object of
`the present
`invention is to provide a vehicle information
`communication device and a vehicle information commu-
`nication system capable of simply setting the characteristics
`of the vehicle onboard device capable of changing the
`characteristics.
`
`DISCLOSURE OF INVENTION
`
`To achieve the above objects, a vehicle information
`communication device in the invention described in claim 1
`comprises control means for a vehicle which is mounted in
`the vehicle and is connected to a vehicle onboard device
`
`having characteristics capable of being changed, and which
`stores characteristic values for determining the characteris-
`tics of the vehicle onboard device and controls the charac-
`teristics of the vehicle onboard device using these charac-
`teristic values; and communication control means which can
`be connected to said control means for a vehicle, and which
`stores characteristic values for determining characteristics of
`said vehicle onboard device, including previously predeter-
`mined characteristic values of said control means for a
`vehicle, and also reads characteristic values stored in said
`control means for a vehicle and obtains stored characteristic
`values corresponding to the read characteristic values, and
`updates characteristic values stored in said control means for
`a vehicle to said obtained characteristic values.
`In the vehicle information communication device
`described in claim 1, the invention described in claim 2 is
`characterized in that said communication control means
`accumulates, as said stored characteristic values, vehicle

`information is communicated between control means for a
`
`20
`
`vehicle for controlling characteristics of a vehicle onboard
`device mounted in the vehicle using characteristic values for
`determining the characteristics of the vehicle onboard device
`and characteristic value memory means provided externally
`of said vehicle and storing said characteristic values,
`wherein: said control means for a vehicle comprises a
`plurality of device control means each controlling charac-
`teristics for determining the characteristics of each vehicle
`onboard device governed by the device control means and
`each device control means stores characteristic values for
`determining the characteristics of said vehicle onboard
`device as main characteristic values, and has memory means
`capable of storing characteristic values for determining
`characteristics of another vehicle onboard device as sub-
`characteristic values, and controls the characteristics of the
`governed vehicle onboard device on the basis of the main 3
`characteristic values stored in the memory means; said
`control meansfor a vehicle stores the characteristic values of
`the governed vehicle onboard device in each of the memory
`means of said device control means as main characteristic
`values, and stores main characteristic values other than the
`main characteristic values to be stored in at least one of said
`memory means in this memory means as subcharacteristic
`values; and said control meansfor a vehicle obtains the main
`characteristic values and the subcharacteristic values stored
`in each of the memory meansof said device control means,
`and calculates the main characteristic values of the device
`control means relative to the obtained subcharacteristic
`values on the basis of the obtained subcharacteristic values
`and the main characteristic values stored in the memory
`means of the device control means relative to these sub-
`characteristic values, and updates the calculated main char-
`acteristic value to the main characteristic values of the
`memory means of said device control means.
`In the invention of claim 1, the control means for the
`vehicle controls the characteristics of a vehicle onboard
`device mounted in the vehicle by the stored characteristic
`values. Vehicle onboard devices include interior electric
`
`40
`
`5
`
`mounted devices such as a headlamp device, etc., chassis
`devices such as a suspension device, etc. Guiding devices
`such as a communication device, a navigation system, etc.
`capable of changing characteristic values of a telephone and
`the like provided within the vehicle can be adopted as a
`vehicle onboard device. The characteristic values of these
`communication devices may consist of a telephone directory
`for storing dial numbers determined in advance and regis-
`tered by a user, sound volumes at
`the time of
`communicating, and the like. The characteristic values of the
`
`60
`
`65
`
`6
`guiding device may consist ofdisplay ranges ofdestinations
`and map information, etc. This control means forthe vehicle
`can be connected to the communication control means. This
`communication control means stores the characteristic val-
`ues for determining the characteristics of the vehicle
`onboard device including the previously determined char-
`acteristic values of the control means for the vehicle. The
`communication control means reads the characteristic val-
`ues stored in the control means for the vehicle and obtains
`the stored characteristic values corresponding to the read
`characteristic values. The communication control means
`
`also updates the characteristic values stored in the control
`meansfor the vehicle to the obtained characteristic values.
`Thus, the characteristic values stored in the control means
`for the vehicle are read and the corresponding characteristic
`values are obtained and updated so that the characteristic
`values stored in the control means for the vehicle can be
`updated to optimum characteristic values and the character-
`istic values of the control means for the vehicle can be
`adjusted to the best state.
`In the invention of claim 2, as mentioned above, the
`control means for the vehicle controls the characteristics of
`the vehicle onboard device such as a interior electric
`mounted device such as a headlamp device, etc. mounted in
`the vehicle, a chassis device, etc. such as a suspension
`device, etc. by the stored characteristic values. There is an
`ECUfor performing control governing each of these vehicle
`onboard devices in this control means for the vehicle. This
`control means for a vehicle is connected to the communi-
`cation control means. This communication control means
`can be connected to accumulating means for accumulating
`vehicle information including the previously determined
`characteristic values of the control means for a vehicle. The
`accumulating means consists of a technology center and a
`central processing center for collecting various kinds of
`technical information, etc. In the vehicle information, the
`type of vehicle having the characteristic values can be set as
`attribute information with respect to the characteristic val-
`ues.
`
`It is possible to treat the characteristic values in accor-
`dance with the type of car by adding the type of car to the
`vehicle information even when the characteristic values are
`different for each type of car. The communication control
`means reads the characteristic values stored in the control
`meansfor the vehicle as vehicle information and obtains the
`vehicle information accumulated in the accumulating means
`and corresponding to the read vehicle information. The
`vehicle information can be read when the characteristics of
`the vehicle onboard device are adjusted by a dealer,etc.
`The communication control means also updates the char-
`acteristic values stored in the control means for the vehicle
`to characteristic values included in the obtained vehicle
`information. The communication control means consists of
`a controller of a dealer, an automobile inspection place, etc.
`able to be connected to the vehicle and able to be also
`connected to the technology center, etc. by a telephone
`circuit etc. Thus,
`the characteristic values stored in the
`control meansfor the vehicle are read and the corresponding
`vehicle information is obtained and the characteristic values
`are updated so that the characteristic values stored in the
`control means for the vehicle can be updated to optimum
`characteristic values and the characteristic values of the
`control meansfor a vehicle can be adjusted to the beststate.
`In the invention of claim 3, the communication control
`meansis connected to the control meansfor the vehicle and
`the accumulating means. The communication control means
`reads the characteristic value stored to the control means for
`
`

`

`6,127,947
`

`the vehicle as vehicle information and obtains the vehicle
`information accumulated in the accumulating means and
`corresponding to the read vehicle information. The commu-
`nication control means then updates the characteristic value
`stored to the control means for the vehicle to a characteristic
`value included in the obtained vehicle information. Thus,the
`characteristic value stored to the control means for the
`vehicle is read and the corresponding vehicle information
`accumulated in the accumulating means is obtained and the
`characteristic value is updated. Accordingly, the character-
`istic value stored to the control means for the vehicle can be
`
`ta
`
`8
`receiving means for receiving information from the control
`meansfor the vehicle by the communication control means,
`and transmitting means for transmitting said information to
`said control means for the vehicle. When this communica-
`tion control means transmits and receives information
`including the characteristic value between the control means
`for the vehicle and the communication control means, the
`receiving means and the transmitting means simultaneously
`perform at least one portion of the reception of the infor-
`mation in the receiving means and the transmission of the
`information in the transmitting means. Thus, the communi-
`cation control means can simultaneously transmit and
`receive the information bidirectionally so that the commu-
`nication load is reduced.
`
`When the above information is transmitted and received,
`it is necessary to confirm the requested information on both
`sides so as to reliably transmit and receive the requested
`information. Therefore, as described in claim 7, said com-
`munication control means receives the request information
`requested from a vehicle side from the control means for the
`vehicle, and transmits reply information showing a reply to
`the request
`information from the communication control
`means to the control means for
