The increasingly stringent CO2 emissions legislation for automobiles presents a particular challenge to the sports car segment due to its low-weight vehicles with a high level of engine power. The key to success in this segment is to meet future emissions limits while simultaneously maintaining or even increasing vehicle agility and driving pleasure. In addition to exploiting the potential of combustion engines, through features such as turbocharging or downsizing, plug-in hybridization offers further solutions in the development of an efficient powertrain. In the field of hybridization, a wide variety of topologies are currently under discussion. In this context, Bosch Engineering GmbH has investigated the efficiency and driving performance provided by various hybrid topologies, and has presented the optimal configuration, in the form of a demonstrator vehicle, by modifying an existing series sports car. In addition to the existing combustion engine, this vehicle was equipped with two individual electric motors fitted to the wheels on the front axle, which improve driving dynamics as well as enable hybrid operation. To increase the efficiency of the powertrain still further, a third electric motor was integrated in parallel to the combustion engine. The smooth interaction between the additional components and the existing system is controlled by integrating hybrid functions in the Engine Control Unit (ECU) and the Electronic Stability Control (ESC) system. The gained experience in the topology of a sports car can be applied to other passenger car segments, as well as commercial and off-highway vehicles, thanks to a modular hybrid platform concept also developed by Bosch Engineering. In addition to its innovative hybridization of the powertrain, the demonstrator vehicle developed by Bosch Engineering also provides a platform for implementing a wide range of solutions aimed at personalization of the individual driving experience. These attractive and close-to-production solutions for demanding end customers include the use of a force feedback accelerator pedal for intuitive feedback regarding driving conditions, the use of GPS and navigation data with an electronic horizon for predictive calculation of driving events as well as the creation of a simple interface for the driver to adjust the vehicle characteristics.
