IPC: F02D41/04
Filed: 1988-03-28
Abstract: PURPOSE:To improve the starting characteristics of an equipment which makes the throttle control to restrain the idling when a driving wheel is detected for idle running by changing the throttle closing rate of a throttle valve being controlled, according to the magnitude of an angle at which the throttle valve is opened when it starts closing. CONSTITUTION:The vehicle running speed corresponding to the engine revolution speed is calculated by an arithmetic operation circuit 3 from the outputs from an engine revolution speed sensor 1 and a gear position sensor 2 and the average value of wheel speeds, that is, control starting reference speed is calculated by an arithmetic circuit 7 from the wheel speeds of left and right driving wheels. When the control starting reference speed exceeds a threshold value, the throttle control starts and an acceleration state is determined according to the vehicle speed corresponding to the engine revolution speed, a control logic circuit 13 determines whether or not a throttle valve is starting decreasing in angle. When YES, a throttle valve closing rate is changed according to the magnitude of the angle at which the throttle valve is opened at the time when the throttle valve is starting to be closed.
