`Abstract
`
`In this paper the different motivations behind the development of hybrid cars are
`examined and various hybrid configurations are illustrated which can satisfy a
`wide range of different and contrasting user needs.
`Specific attention is then given to the definition of guidelines for the
`development
`of a hybrid car where parallel configuration of the propulsion system allows the
`rulfillment of two types of mission:
`
`- short trips in urban areas with zero emissions by only using the electric motor
`driveline;
`' long highway trips with performance close to that of conventional cars but
`lower emissions.
`
`The corresponding design criteria for a Fiat medium size hybrid car are described
`together with the propulsion system, consisting of an AC. electric motor and an
`ICE, that has been implemented and bench tested. A prototype car has also been
`equipped with this hybrid system and the driveability demonstrated.
`The management of the two propulsion units: electric motor and ICE is
`performed via an ECU using suitable control Iogics to optimize, in terms of
`consumptions, emissions and battery energy management, the performance of
`the global system.
`
`Introduction
`
`In the last years the legislation scenario and the attention to the environmental
`issues have changed, also in relation with the inconvenience produced by the
`traffic density in the most congested urban centers; as a consequence the research
`and development effort of the automotive and component manufacturers has
`changed, in order to better cope with the problems which did not allow up to
`now an industrial development of the environmental friendly electrically

`
`
`
`propelled vehicles.
`The range and performance limits which are tied to the characteristics of the
`batteries presently available or under development (power, energy, weight,
`volume) remain the principal obstacle against the electric traction diffusion, even
`within the assumption of the european scenario which forecasts the
`establishment of areas with circulation reserved to ZEV vehicles.
`A recent study of the MIP Consortium in Milan has put in evidence that only
`10% of the vehicles in circulation in the Milan area could be substituted by
`electric vehicles, provided that they can assure a real range of 85 Km. On the
`contrary, the hybrid vehicles, featuring a range in pure electric of some 40 Km,
`would allow a substitution of approximately 90% of the vehicle park.
`This study, whose results can be extended to other italian and european cities,
`puts in evidence the enormous potential of hybrid vehicle.
`The introduction of such a vehicle into the market, could have indeed an
`important impact on the enviromental quality improvement of the more
`congested urban areas and, in general, on the global pollution.
`
`Alternative hybrid vehicle configurations
`
`The hybrid vehicle features a powertrain which integrates a then-rial engine with
`an electric motor.
`Toward the hybrid vehicle approach, various possible configurations have been
`examined. [1]
`The addition of an independent electric power-train on the thermal vehicle
`originates the simplest mixed con.fig-uration, called "dual mode".
`The two powertrains operate in alternative, to meet the requirements of the
`circulation in typical urban areas (electric traction) or those of the extraurban
`missions {thermal engine).
`This configuration allows the following advantages:
`
`- it does not require the integration of two powertrains; as a matter of fact, the
`simplest configuration is related to a conventional front drive ICE to which an
`electric powertrain is added on the rear axle.
`- it offers the possibility to make available a drive system on the two axles in the
`cases of critical mobility.
`
`On the other hand, some constraints exist:
`
`9 qitical layout due to the encumbrances on the two traction axles, with
`considerable modifications on structure and mechanics;
`o vehicle performance in the thermal mode penalized by the higher weight due
`to electric motor, related electronics and batteries:
`- system not optimized in terms of consumption and emissions.
`
`Another possible configuration is the series hybrid, which is constituted by a
`generating unit (thermal enginelelectric generator) and by the electric
`powertrain.
`For this configuration, the following advantages are envisageable:
`
`£159
`

`
`20
`
`
`
`- utilization of the thermal engine within the most favourable working
`conditions in terms of efficiency. This offers the possibility, for a mission
`featuring variable speed and low power, of limiting the emissions of the
`traditional pollutants, to the minimum allowed by the technology;
`- equal vehicle performance in the electric and hybrid modes.
`
`On the other hand, the most important disadvantages of this configuration are:
`
`- the number of installed components (two electrical machines besides the
`thermal_ engine}, which have an impact on the vehicle in terms of weight,
`volume and cost;
`
`- low efficiency over constant speed runs, as a consequence of the energy
`conversions {thermal-electrical-mechanical).
`
`A further possible configuration is the parallel hybrid.
`This solution, albeit a higher mechanical and system complexity, utilizes the
`combination of the two engines (thermal and electric), adding on the same shaft
`the respective torque and power to achieve the desired performance.
`In this case the advantages of the system can be summarized as follows:
`
`- low installed electric power, related to the urban mission, with consequent
`weight and volume reduction;
`- possibility of a direct conversion of the thermal energy into mechanical, with
`higher global efficiency of the system;
`- addition of the electric power to that of the thermal engine,'with power peaks
`covered by the electric motor.
`
`However, it is necessary to overcome the critical aspects deriving from the
`integration of the two systems, that are:
`
`- mechanical complexity;
`- complexity of the system for control and simultaneous management of the two
`propulsion systems.
`
`As far as the cost aspect is concerned, taking as a reference an electric vehicle of
`the same size, the hybrid vehicle would feature as follows:
`
`0 the electric motor is of slightly smaller power;
`
`- the battery can be of lower capacity (roughly one half};
`- a thermal engine of relatively low power is added which is taken from the
`conventional mass production;
`- a mechanical transmission is substituted to that of the electric vehicle; a specific
`mechanical interface is added.
`
`Therefore, in this preliminary development phase. a not unreasonable goal
`would be a substantial equivalence of cost between the parallel hybrid and a put
`electric vehicle of the same size.

`
`Research and development activity in FIAT
`
`The optimum choice of the hybrid vehicle configuration is strictly connected
`with the mission. FIAT R8:D activities in the field of electric traction are lined up
`to the development trend in Europe, where the reference mission can be
`summarized as follows:
`
`- city centers with mobility restricted to ZEV vehicles
`- extraurban and motorway runs with performances comparable to those of
`conventional vehicles.
`
`The uncertainties of the evolution of the market and of the introduction
`procedures of the regulations did not prevent activities on large fields of
`investigation, both to assess the different technology options and to identify the
`best synergy of thermal!electric!hybrid vehicle.
`The cost constraint requires a strong attention to the carry over among the
`various vehicles and in particular to the conventional I'|DI'1'l'lal production
`vehicle.
`Research activities have been started on a hybrid vehicle with parallel
`configuration, derived from a conventional medium size car; pursuing the best
`compromise among technical complexity, cost and performance, keeping the
`same characteristics of roominess. comfort, active and passive safety; in
`particular, design solutions have been followed which limit the required
`modifications on the basic vehicle and optimize the number of components
`drawn from the conventional vehicles already in production, keeping the Final
`price of the product within acceptable values.
`In order to verify the functionality of the whole system and the potential of the
`technical choices. a demonstrator prototype of the hybrid vehicle has been
`designed, manufactured and tested both at the test bench and on the road.
`The global objectives of the vehicle, the specificafions of the subsystems and the
`prel.i.rn.inary experimental results are discussed in the following paragraphs.
`
`Overall objectives and systems specifications
`
`The performances of the hybrid vehicle compared with those of the basic
`conventional vehicle are shown in Tab. 1, with reference to the operating modes
`electric and hybrid; the use of the pure "thermal" traction is considered only for
`the cases of some anomalous behaviour of the system.
`Throughout a preliminary investigation with mathematical simulation models,
`the deployment of the overall objectives has been performed into subsystem
`specifications.
`Tab. 2 exhibits the characteristics of the main group of the hybrid system. in this
`first phase of the project, the maintenance free Pb/Gel battery has been
`considered for the energy storage system.
`This choice does not hinder the further use of new batteries for the optimization
`of the system in terms of weight and encumbrances.

`
`
`Vehicle Packaging
`
`The hybrid vehicle under study is derived from the conventional model of
`normal production FIAT TEMPRA, which features a weight of some 1100 Kg and
`the following external dimensions:
`
`- Length: 4354 mm; wiclth= 1695 mm; Height: 1-145 mm
`
`The conversion requires a careful analysis of the main design constraints, which
`bring to a deep review of the layout of all subsystem, with a considerable weight
`increase related to the energy strorage system and to the double drive system {A
`weight -4SUKg).
`The established layout is shown in Pig. 1.
`In order to obtain dynamic characteristics equivalent to those of a conventional
`vehicle, it has been necessary to redefine the main parameters of the suspensions
`(stiffness, damping) according to the new operating conditions.
`In order to obtain the same working conditions and driving comfort within the
`different modes, electric and hybrid, power steering and power braking are
`supplied by electrical pumps.
`The weight increase of approximately 40% over the basic vehicle has requested
`considerable modifications on the structure in order to make the hybrid vehicle
`consistent with the safety standards and with the strength and the stiffness of
`conventional vehicles.
`Preliminary analyses performed by means of computer simulations have
`produced indications on the guidelines to follow in the definition of the
`structural modifications.
`in order to make the interventions compatible with the industrial constraints, it
`has been decided to modify the structure mainly in the lower part, as shown in
`the scheme of Fig. 2. With reference to consumption and emissions, the
`developed solution allows to counterbalance the negative effects due to the
`weight increase, since it allows to:
`
`- install a thermal engine of reduced power insofar the maximum performances
`are given by the sum of the power of the thermal engine and of the electric
`motor, with benefits in terms of overall efficiency at the same total output
`power;
`o recover energy during braking phases, thus reducing the negative impact due
`to weight increase;
`- use the electric motor and the thermal engine in the highest efficiency
`conditions, through the optimization of the control strategy of the system;
`- reduce the emissions both in transient and starting conditions, through an
`
`appropriate control strategy.
`
`Hybrid powertrain
`
`In fig. 3 the main components of the hybrid powertrain are shown. Preli.m.inary
`bench tests have been performed on all main components, in order to verify
`their characteristics in terms of performance, efficiency and encumbrances (Fig.4).

`
`- Thermal engine
`- The thermal engine defined for th.is application (1242 c.c.) is taken from the
`series production and features an injection system MP1, which allows better
`potential in terms of emission control.
`The software of the electronic un.it (WEBER LAW) has been modified to
`implement new control strategies in the transients and to achieve the
`stoichiometric control over the whole working range.
`Further interventions have been necessary to equip the powertrain with the
`DRIVE-BY-WIRE system.
`- Electric‘ motor
`
`- As a starting point for the development of this project, a synchronous variable
`reluctance motor with high torque and efficiency has been adopted [2].
`The motor, which has been designed for the application to an electric vehicle,
`features a high utilization range, low weight and reduced dimensions, which
`have been made possible by integrating the liquid cooling system both for the
`motor and for the inverter.
