ABSTRACT:
A device for controlling the braking force of a motorcycle in two controlling modes: a normal mode and an antilocking mode, comprises tachometers mounted on front and rear wheels of the motorcycle, an accelerometer mounted on the motorcycle body, and a control circuit. The control circuit calculates a peripheral acceleration of each wheel based on the peripheral velocity of each wheel, and a slippage ratio of each wheel based on the peripheral velocity of the wheel and the acceleration of the motorcycle body. When the slippage ratio and the peripheral acceleration of one wheel meets given conditions, the control circuit starts, prior to entering into the antilocking mode from the normal mode, to calculate the coefficient of friction between the road surface and the one wheel. For the other wheel, the coefficient of friction is calculated in the same manner.
