Abstract
The control device for a closure member of a vehicle according to the present invention comprises: estimated load calculation means () for obtaining an estimated load from a rotation speed, acceleration, and drive voltage of a DC motor () for driving a closure member (); motor torque calculation means () for calculating a motor torque from the rotation speed and drive voltage of the motor; reference torque calculation means () for calculating a reference torque based on a stationary state of the motor torque; and pinching determination means () for determining a pinching of an object based on the estimated load, motor torque and reference torque, wherein the pinching determination means determines that there is no pinching when at least one of the estimated load and the motor torque is below the reference torque even when the estimated load is greater than a prescribed threshold value.
