Vehicle driving control device and method

摘要

An improved vehicle driving control device controls a vehicle without giving vehicle occupants a feeling of abnormality during acceleration and deceleration and optimally controls the operating torque of the engine. A vehicle driving control procedure sets the target operation torque of the vehicle and determines a target engine torque and a target engine speed from the target operation torque. Engine control is performed according to the target parameters. To compute each target parameter of the engine, the target output torque of a torque converter is first computed from the target operation torque, to determine the condition of a lockup clutch. Furthermore, each target parameter is computed in accordance with a control law set in accordance with the condition of the lockup clutch.
