Control system for hybrid power vehicle includes control blocks regulating torque from electric and thermal motors in response to operating conditions

摘要

The system monitors the torque demanded in order to determine the optimum source of this power from electric and thermal engines. The system includes a parallel hybrid drive for a motor vehicle, comprising an electric motor (1) and a thermal engine (2) both linked in rotation to a mechanical drive train (3). This allows the motors to provide power selectively to the vehicle wheels (4). The control includes a number of blocks for managing the demand for torque, controlled by a block determining the operating conditions of the vehicle (8), and a block (10) determining the couple received and receiving information from other monitoring blocks (6,7,12). A further system determines the status of the alternator-starter (9), in order to control the couple provided by both the electric motor and the thermal motor, optimizing the performance compromise between performance and efficiency.
