Abstract
A vehicle control device controls a vehicle drive system including a main motor as a drive source of a vehicle, a parking lock mechanism, and an actuator. The vehicle control device includes an actuator drive control section that controls a drive of the actuator, a main motor drive control section that controls a drive of the main motor, and a range determination unit that determines whether or not a shift range is a parking range. When releasing the parking lock, if the parking range is not released within a parking range release determination time that is variable according to an operating environment, the main motor drive control section performs a meshing surface pressure reduction control for driving the main motor so as to reduce a meshing surface pressure between a parking gear and a parking lever.
