Patent ID: 6950739

Claim:
A motor control device for a vehicle having a deceleration deactivatable engine, wherein, during a deceleration traveling of said vehicle, a fuel cut operation is applied to said engine as well as a deceleration cylinder deactivation operation in which at least one cylinder is deactivated in accordance with a running state of said engine, and said engine is started by a motor when the operation of said engine transitions from the fuel cut operation to a fuel supply operation, said motor control device comprising: a cylinder deactivation state determining section for determining whether or not said engine is in a cylinder deactivation state; a cylinder deactivation executing section for executing the cylinder deactivation operation of said engine; a cylinder deactivation operation detecting section for detecting whether or not said cylinder deactivation executing section is activated; and a starting torque setting section for setting starting torque for starting said engine by said motor, wherein when it is determined, by said cylinder deactivation state determining section, that said engine is in a cylinder deactivation state, and it is determined, by said cylinder deactivation operation detecting section, that said engine is to return to the fuel supply operation, said starting torque setting section sets a smaller staring torque than in the case in which said engine returns to the fuel supply operation from a state in which it is determined, by said cylinder deactivation state determining section, that said engine is not in a cylinder deactivation state.
