Abstract:
1. A braking system for a vehicle comprising: an operating rod couplable to a brake actuator operated by a driver of the vehicle; a first piston system including a first piston, a first fail recovery key, and a first motor, wherein the first motor is coupled to the first piston to affect lateral movement of the first piston and wherein lateral movement of the first piston applies a braking pressure to a first wheel of the vehicle; a second piston system including a second piston, a second fail recovery key, and a second motor, wherein the second motor is coupled to the second piston to affect lateral movement of the second piston and wherein lateral movement of the second piston applies a braking pressure to a second wheel of the vehicle; a fail safe plate fixedly coupled to the operating rod such that lateral movement of the operating rod causes lateral movement of the fail safe plate; and a controller configured to operate the first motor to control the lateral movement of the first piston and operate the second motor to control the lateral movement of the second piston based at least in part on detected movement of the operating rod, wherein, when the first fail recovery key is engaged, the first piston is mechanically coupled to the fail safe plate and lateral movement of the operating rod causes lateral movement of the first piston, and wherein, when the second fail recovery key is engaged, the second piston is mechanically coupled to the fail safe plate and lateral movement of the operating rod causes lateral movement of the second piston.
