Title: Electrohydraulic brake by wire system for autonomous vehicles and fully decoupled applications
Inventor: OLIVER RODNEY THOMAS JACKSON
IPC: B60T13/68
Filed: 2021-09-02
Abstract: A system and method for controlling a self-sufficient electrohydraulic brake-by-wire system for use in autonomous or semi-autonomous vehicles or fully decoupled braking applications. Upon detection of a fault or failure in the brake-by-wire system (e.g. valve malfunction), a controller switches from a first configuration to a second configuration. In the first configuration, a flow of volume of pressurised fluid from a reservoir 138 via a pump 144 and/or an accumulator 136 to brake calipers 150, 152 is via a primary route 300, in which first solenoid valve 120 is engaged (open) and second solenoid valve 132 is disengaged (closed). In the second configuration, the flow is via a secondary route (400, fig. 4) in which first solenoid valve 120 is disengaged (closed) and second solenoid valve 132 is engaged (open). The two routes are included for redundancy. There may also be a crosslink valve 130 between two brake calipers on the same axle. There may also be a pressure relief valve 134 to relieve excess fluid from the accumulator or pump.
