An electric parking brake control unit of an electric parking brake apparatus has an input section for receiving signals for performing automatic activation and deactivation, but does not have a determination function and a circuit for inputting signals from various sensors, which are necessary to determine whether to start the automatic activation/deactivation control. Therefore, when used in a vehicle which does not require an automatic control function and requires only a manual control function, the electric parking brake control unit can be used solely, with no signal line connected to the input section. When used in a vehicle which requires both the automatic control function and the manual control function, the input section is connected to a second control unit that can output signals for performing automatic activation and deactivation, whereby the electric parking brake control unit operates in cooperation with the second control unit.

Electric parking brake apparatus

A heat dissipation device is disclosed for dissipating the heat produced by electronic components () of an electronic control device. The electronic control device includes a circuit board (), a resin protective case (), and a metal actuator block (). The electronic components are mounted on the circuit board. The protective case confines the circuit board within a thermally restrictive environment. The actuator block is mounted to the outside of the protective case. The heat dissipation device includes a heat conduction path () that serves to thermally conduct the heat produced by the electronic components from the interior of the protective case to the actuator block.
