Abstract
A braking force controlling apparatus changes a magnitude of a braking force produced by a braking operation based on a speed of the braking operation. The braking force controlling apparatus is directed to maintaining a brake-assisting control even when a beginner unintentionally releases a braking operation force on a brake pedal. A hydraulic pressure sensor (40) detects a master cylinder pressure, and a maximum master cylinder pressure during the braking operation of the brake pedal (30) is stored in an ECU (10). When the master cylinder pressure is found to be below a release-judgment level of the master cylinder pressure, which is determined based on the maximum master cylinder pressure, the brake-assisting control is terminated. When the master cylinder pressure is found to be above the release-judgment level, the brake-assisting control is maintained.
