Abstract
A vehicle control device is provided with a friction clutch for engaging and disengaging a motor/generator and a drive wheel, a mechanical oil pump driven by the motor/generator to supply hydraulic oil pressure to the friction clutch, an electric oil pump driven by an electric motor to supply hydraulic oil pressure to the friction clutch, and a control unit. The control unit stops a motor/generator when a vehicle stops; maintains a release of a friction clutch when slack in the stroke is eliminated by the hydraulic oil pressure from the electric oil pump; raises a rotational speed of the motor/generator toward a target rotational speed upon a request to cancel stoppage of the motor/generator; and restricts the torque to be less than the motor generator torque at which the target rotational rate can be maintained when the rotational rate of the motor/generator is raised toward the target rotational rate.
