<P>PROBLEM TO BE SOLVED: To provide a motor lock control unit for vehicles capable of preventing the failures of vehicle-mounted motorized equipment as well as capable of promoting the effective utilization of resources and the reduction in the costs of raw materials without the need to provide separately a motor protective circuit. <P>SOLUTION: A motor lock control unit is disposed in a vehicle, as well as is provided at some midpoints of a feeder line 530 for establishing the electrical connection between a DC electric power unit 510 and an electric current motor unit 520, and includes an electric current detecting means 111(110) for detecting an electric current that flows through the feeder line 530, and a PWM controlling means 112(110) for PWM controlling an electric current that flows through the feeder line 530, in the case that detected values of the electric current detecting means 111(110) are greater than a first predetermined current threshold (It<SB>(1)</SB>). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
