Abstract
The present invention relates to a control apparatus for a vehicle equipped with an electronic throttle control unit (drive by wire) as electronic throttle control means and an automatic transmission, and the object of the invention is to provide a control apparatus for a vehicle which is capable of ensuring stable travel even in the case where a throttle valve is stuck by a failure of an electronic throttle control unit. In a control apparatus for a vehicle equipped with electronic throttle control means for electrically driving a throttle valve by drive means and an automatic transmission having a plurality of speed change gear stages, the control apparatus is provided with sticking judgment means for judging whether or not the throttle valve has been stuck, and speed change regulation means for inhibiting use of a predetermined gear stage among the speed change gear stages of the automatic transmission in the case where the throttle valve is judged to have been stuck by the sticking judgment means.
