The present disclosure relates to a vehicle having a park-by-brake module that can control an electronic parking brake coupled to the rear wheels of a vehicle. The park-by-brake module is coupled to an antilock brake module by a controller area network architecture. In one example, a first controller area network and a second controller area network are used to couple the park-by-brake module to the antilock brake module. The controller area network architecture allows the park-by-brake module to receive commands from various control modules. Based on the received commands, the park-by-brake module activates or deactivates the electronic parking brake.

System and method for controlling an electronic parking brake

A hydraulic boost valve includes a housing, a valve seat, and a piston. The housing defines an axially extending internal cavity, a slot that extends radially outward from the internal cavity within the housing, and an outlet port that establishes fluid communication between the slot and a fluid output circuit. The valve seat is secured to an end of the housing. The valve seat defines first and second orifices. The first orifice establishes fluid communication between a fluid input circuit and the outlet port via the slot. The second orifice establishes fluid communication between the fluid input circuit and the fluid output circuit. The piston is disposed within the internal cavity such that the slot is positioned between the piston and an external wall of the housing.

Methods and systems are provided for a zero hysteresis valve. In one example, a valve comprises protrusions shaped to maintain a distance between a moveable portion of the valve and a valve seat.
