Abstract
A braking force controller for an electric vehicle properly carries out an anti-lock braking operation by keeping a slip ratio in a stable range. The vehicle has a motor 1 to drive wheels. A central controller 4 calculates regenerative energy according to output signals from an ammeter 51 and a voltmeter 52. If a brake sensor 62 detects a sudden braking operation, the central controller 4 controls the regenerative braking force of the motor 1 through a motor controller 2, to maintain the regenerative energy around a maximal value.
