Abstract:
A valve includes an electrical park valve configured to receive an electrical park signal and to allow hydraulic fluid to flow through a first electrically-controlled channel in response to the signal indicating a parking request, and a main valve configured to receive the hydraulic fluid from the first electrically-controlled channel and to allow the hydraulic fluid to flow to a braking actuator in response to receiving the hydraulic fluid. The valve also includes an electrical emergency control valve configured to allow the hydraulic fluid to flow through a first control channel in response to a request for emergency braking. The valve also includes an emergency enable valve configured to receive the hydraulic fluid from the first control channel and to allow the hydraulic fluid to flow to the braking actuator in response to receiving the hydraulic fluid from the electrical emergency control valve.
