Abstract

See full text

A vehicle engine control device includes an operation-degree detecting device for detecting the degree of each operation of a manually operated member effected to control the output of the engine via a throttle valve actuator and a throttle valve; a target acceleration setting device for generating a target acceleration signal corresponding to the degree of the operation of the manually operated member; an acceleration detecting device for detecting each operative acceleration of the vehicle; and a control signal outputting device for comparing the target acceleration signal, which has been generated from the target acceleration setting device, with the detection results from the accelerating detecting device and then outputting a control signal to the actuator so as to control the degree to which the throttle valve is opened in such a way that the operative acceleration of the vehicle is controlled to the target acceleration.
