Abstract

A brake controlling apparatus includes a gradient sensor, an operation unit, a brake controlling unit, and a storage unit. The gradient sensor is configured to detect a road gradient. The operation unit is configured to switch a constant speed downhill traveling function to become effective. The brake controlling unit is configured to control first and second regenerating units configured to generate regenerative electric power from braking torques of front and rear wheels, respectively. The storage unit is configured to hold an efficiency map. In a case where the constant speed downhill traveling function is caused to become effective, the brake controlling unit is configured to calculate braking torque distribution between the front and rear wheels based on the road gradient and the efficiency map to cause total regeneration efficiency to satisfy a first condition, and control the first and second regenerating units on a basis of the braking torque distribution.
