20130320751 | DUAL CIRCUIT PNEUMATIC FOOT VALVE WITH ELECTRONICALLY CONTROLLED PROPORTIONAL MODULATOR (ECPM) AND OPERATOR INPUT SENSING - A foot valve that can be activated either by the driver or an electronic control unit, wherein the foot valve can be the central driving device for automated braking applications such as Hill Start Aid and Work Brake Systems. Pneumatic pressure delivered by an electronically controlled proportional modulator to the foot valve activates either primary and/or secondary portions of the brake valve. The driver can mechanically override the electronic intervention when he presses on the brake pedal. For applications such as ESC and ATC, driver demand can be sensed by sensors in the foot valve and transmitted to the braking system electronic controller on the vehicle. | 12-05-2013 |
