Abstract (en)
[origin: EP0495295A2] A throttle valve control system for an engine of a vehicle is disclosed of the type having a rotatable throttle valve controlled by an electronic control means. The control means (21) being operable to increase the effort supplied to the throttle valve (14) when the throttle valve (14) approaches its closed position in order to reduce the effect of stiction and friction on the control system response. The increase in effort is obtained by increasing momentarily the system gain or providing a step input of predetermined magnitude. <IMAGE>
