  • Power assisted braking system with wheel lock control
    Patent number: 4576417
    Abstract: A brake control system in which the master cylinder has two pressurizing chambers for each brake circuit. Three brake circuits are disclosed in detail. One piston of each set of pressurizing chambers is directly applied by brake pedal force. The other piston of each set receives brake pedal force through resilient means, with additional force supplied by suitable servomotors. The servomotors are individually controlled to provide power-assist when appropriate, or to decrease the forces supplied by them to control wheel slip or wheel spin.

  • Integration of regenerative braking and conventional braking
    Patent number: 4181366
    Abstract: A vehicle braking system with regenerative braking and conventional braking, the system integrating the two braking forces to obtain a consistent total braking effort and brake pedal feel when the regenerative braking force decreases with the decrease in vehicle speed.
