Abstract: A vehicle is provided. The vehicle includes a brake-by-wire sub-system, which includes a controller. The controller receives a request to enter a service mode. In response to the request to enter the service mode, the controller determines whether a vehicle is in a stable state based on comparing at least one system condition against at least one threshold. When the vehicle is in the stable state, the controller causes the brake-by-wire sub-system to enter into the service mode. Further, the controller monitors the at least one system condition against predefined parameters to determine that the vehicle is maintaining the stable state while in the service mode.

Abstract: A brake pedal apparatus for actuating a vehicle brake assembly includes a stationary structure, a brake pedal emulator assembly, and an emulator override device. The brake pedal emulator assembly includes a brake pedal operatively engaged to the stationary structure, and a brake pedal emulator operatively engaged between the stationary structure and the brake pedal along a centerline. The brake pedal emulator is configured to electrically operate the brake assembly. The emulator override device includes a mechanical linkage operatively engaged to the brake assembly, and a latch configured to selectively connect and disconnect the mechanical linkage from the brake pedal emulator assembly. The mechanical linkage is configured to mechanically operate the brake assembly via at least in-part movement of the brake pedal along the centerline.

Abstract: A vehicle includes a plurality of brake assemblies and a plurality of electronic brake system (EBS) controllers. The brake assemblies each include an electro-mechanical actuator configured to adjust a torque force applied to a wheel of the vehicle. The EBS controllers are located remotely from one another. Each EBS controller has integrated therein an electronic actuator driver unit that includes an electronic power circuit configured to drive at least one of the electro-mechanical actuators. A first EBS controller is configured to drive a first group of electro-mechanical actuators, and a second EBS controller is configured to drive a second group of electro-mechanical actuators that exclude the electro-mechanical actuators of the first group.

Abstract: A brake pedal emulator extends and is connected between a support structure and a brake pedal along a centerline. The emulator includes a hydraulic cylinder, a piston head, and a variable flow communicator. An outer casing of the cylinder engages one of the structure and the pedal. The piston head engages the other of the structure and the pedal, and the communicator is carried between the casing and the piston head. A first chamber is defined at least in-part by the casing and a first side of the piston head, and a second chamber is defined at least in-part by the casing and an opposite second side of the piston head. The piston head is in sealed and slides with respect to the casing, and the communicator is adapted to provide fluid communication between the first and second chambers that varies with axial displacement of the piston head.

Abstract: A vehicle is provided. The vehicle includes a vehicle system. The vehicle system includes a brake-by-wire portion, which also includes a controller. The controller can cause a forced coastdown of the vehicle. The forced coastdown includes performing analyzing conditions of the vehicle system to determine whether the vehicle is in a stable state and to determine an amount of energy available to the vehicle system and automatically applying the forced coastdown when the vehicle is not in the stable state and the amount of energy is less than or equal to a threshold for continued manual operation of the vehicle. The forced coastdown also includes utilizing brake pressure to reduce a speed of the vehicle.
