Control system for controlling behavior of vehicle e.g. hybrid vehicle, has sub-electrical control unit to determine that control section correctly works, based on comparison result of physical quantity and value detected by sensor

摘要

The control system has electrical control unit (10) with monitor (18) to monitor whether computer (14) correctly calculates behavioral target value and nominal value of common sub-electrical control units (30,40,50). The sub-electrical control unit has conversion section that converts target value of sub-electrical control units without comparing physical quantity with value detected by sensor. The sub-electrical control unit has determination section to determine that control sections (34,44,54) correctly work based on comparison result between physical quantity and detected value. The electronic control unit calculates a target behavior-relevant value of the vehicle behavior. The sub-control units determine and outputs common electrical reference value to each sub-control electric unit. Each slave electric control unit controls an operating state of corresponding in-vehicle apparatus based on common reference value of slave electric control unit from master electric control unit. The sub-electrical control units have control section of in-vehicle apparatus to set operation state relative to common set point without need for verifying whether operational status of in-vehicle device is properly regulated.
