Claim:
1. An electric parking brake control device which includes a brake temperature detection device which detects a brake temperature based on a selected temperature rise, comprising: a first acquisition means that acquires a kinetic-energy based temperature rise, which is a temperature reading increase calculated based on an increase in an amount of brake heat that occurs when kinetic energy generated in a running vehicle is converted into thermal energy by braking; a second acquisition means that acquires a braking-energy based temperature rise, which is a temperature reading increase calculated based on an increase in an amount of brake heat that is calculated from an amount of work done when a brake's friction material is pressed against a friction target material; and a hill determination means that determines state of slope of a road surface on which the vehicle is running, wherein the brake temperature detection device selects the kinetic-energy based temperature rise as the selected temperature rise when the hill determination means determines that the road surface on which the vehicle is running is a flat road surface, and selects the kinetic-energy based temperature rise or the braking-energy based temperature rise, whichever is smaller, as the selected temperature rise when the hill determination means determines that the road surface on which the vehicle is running is an upwardly-sloped road surface, and wherein the electric parking brake control device controls generation of a braking force by an electric parking brake in accordance with the brake temperature previously detected by the brake temperature detection device.
