PURPOSE:To make it possible the detect the full closing of a throttle value with no erroneous detection by measuring a signal variation amount of an engine torque detecting means, and by determining the closing of the throttle value when the variation value is smaller than a predetermined value after the variation value is decreased. CONSTITUTION:An engine torque detecting means 1 for detecting an engine torque in accordance with an output signal from a throttle valve opening degree sensor is provided, and a controller 3 controls an actuator 2 in accordance with input data including an engine torque detected by the detecting means 1. A lock-up control or a speed change control for a torque converter in an automatic transmission 4 is carried out in association with the operation of the actuator 2. In such a control device, the controller 3 is provided therein with a throttle valve full closing detecting means 5 for detecting a signal variation amount of the engine torque detecting means 1 and for determined the full closing of the throttle valve when the variation value is smaller than a predetermined value after the variation value is decreased. |
