Abstract
A control apparatus for controlling the output of a vehicle equipped with an internal combustion engine. The control apparatus includes a torque control unit and an electronic control unit, is electrically connected to various sensors for detecting the running conditions of the vehicle, and is capable of controlling, e.g., the operations of a throttle valve and an ignition plug, to thereby control the driving torque of the engine. The control apparatus calculates a reference driving torque of the engine on the basis of the vehicle speed, and also calculates a slippage of the driving wheels on the basis of a deviation of peripheral speed between the driving and driven wheels. A correction torque for the reference driving torque, which is calculated by the control apparatus on the basis of the detected slippage, is subjected to restriction in accordance with the vehicle running conditions, and the reference driving torque is corrected in accordance with the restricted correction torque, to obtain a target driving torque. Thus, the control apparatus controls the operations of the throttle valve and ignition plug such that the actual driving torque of the engine coincides with the targ…
