Abstract
Providing a control apparatus for a vehicle having a parking lock devicewhich is placed in its released state with a hydraulic pressure generated by an oil pumpoperated by an engine, which control apparatus permits reduction of a risk of unintended releasing of the parking lock deviceupon occurrence of an operating failure of an ON-OFF switching valveor a switching valveof a hydraulic deviceprovided to supply the hydraulic pressure. Engine start restricting meansis configured to restrict starting of the enginewhen a component of the hydraulic deviceprovided to operate the parking lock devicehas an operating failure that causes the parking lock deviceto be held in its released state, as compared with the starting when the component does not have the operating failure, so that the engine start restricting meansreduces a risk of releasing of the parking lock devicedue to application of the hydraulic pressure from the hydraulic deviceto the parking lock device, which application would be caused by the starting of the engine
