1. A vehicle control device for controlling a vehicle drive system,
the vehicle drive system including
a main motor as a driving source of a vehicle,
a parking lock mechanism having a parking gear connected to an axle and a parking lever configured to be engaged with the parking gear so that an engagement of the parking gear and the parking lever allows the axle to be locked, and
an actuator configured to drive the parking lever, the vehicle control device comprising:
an actuator drive control section configured to control a drive of the actuator;
a main motor drive control section configured to control a drive of the main motor; and
a range determination section configured to determine whether a shift range is a parking range, wherein
when the parking lock is released, if the parking range is not released within a parking range release determination time, which 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 the parking gear and the parking lever.
