A controller (102) for driving a motor (105) in a motor driven vehicle (1), provided with: a detection part (1210), a control coefficient computing part (1201), and a control part (1203, 1204). The control coefficient computing part (1201) identifies, as a first vehicle speed, the speed of the vehicle (1) when the detection part (1210) detects a start signal for regeneration control, the control coefficient computing part (1201) assigning a prescribed value to a control coefficient that determines a value of a control parameter that controls the motor (105) relative to a target value of the control parameter. The target value is a value of the control parameter at which the motor (105) achieves a desired power generation efficiency, and the control coefficient computing part (1201) increases the control coefficient if a current vehicle speed becomes higher than the first vehicle speed, and decreases the control coefficient if the current vehicle speed becomes less than the first vehicle speed.
