Control system for dual engined vehicle includes two analysis branches determining couple from each unit contributing to driver required total

摘要

The control system establishes reference values for the couple provided by the internal combustion and electrical engines in a motor vehicle. The control system includes a detector sensing a value (PVAV) which represents the driver's requirement, and further detectors sensing values representing the operation of the vehicle. Two separate analysis branches are provided for the two engine units. The control system enables establishment of reference values for the couple provided by the engines in a motor vehicle which uses two separate engine drive units. One of these is an internal combustion engine (ENG) and one is an electric motor (CSG). The control system includes a detector sensing a value (PVAV) which represents the driver's requirement, and further detectors sensing values representing the operation of the vehicle. Two separate analysis branches (B1, B2; B3, B4) are provided for the two engine units. A reference value of the couple for each engine unit (TQREQENGRAW, TQREQCSGRAW) is determined as a function of the driver requirement value (PVAV) and the operating parameters for the vehicle. These values combine to provide the total output torque required by the driver (TREQDRIV).
