发明名称 Control system for vehicle with automatic transmission.
摘要 A control system for a vehicle including an automatic transmission provided with multiple transmission gear mechanism in which a specific gear stage of a speed ratio is automatically established among a plurality of gear stages in accordance with an vehicle operating condition, shift control signal producing device for producing a shift control signal in order to make a shift operation between different gear stages in accordance with the vehicle operation condition, engine output control device for reducing an engine output in synchronism with the shift operation so as to suppress a torque shock due to the shift operation, detecting device for detecting a specific vehicle operation condition in which a change in a time lag between a generation of the shift control signal and an actual initiation of the shift operation in the transmission is greater than a predetermined level and for producing a signal denoting the specific vehicle operating condition, and restricting device for restricting the engine output control device from reducing the engine output when said specific vehicle operating condition is detected. The torque shock due to the shift operation can be effectively suppressed.
