Anti-lock braking system providing pump motor duty cycle based on deceleration and motor voltage feed back |
摘要 |
An anti-lock braking system (1) includes an electronic control unit or ECU having software which utilizes inputs of deceleration and pump motor voltage feedback to effect an appropriate duty cycle for the pump motor. By utilizing vehicle velocity, calculated vehicle deceleration and wheel deceleration to estimate the type of surface engaged by the vehicle wheels, and utilizing motor voltage to estimate pump load, the duty cycle of the motor may be varied so that low brake pedal effort braking has the benefit of less pump motor operation and reduced pump motor noise.
