    Abstract: A brake-by-wire system includes a controller, a brake assembly, a pedal assembly, and a hydraulic backup assembly. The brake assembly includes a brake and an actuator connected to the brake when the system is in a normal mode. The pedal assembly is coupled to the brake when the system is in a backup mode, and is coupled to the controller when in the normal mode. The controller receives braking signals from the pedal assembly and outputs a command signal to the actuator. The actuator drives the brake in the normal mode. The backup assembly includes a hydraulic line in controlled fluid communication with the brake and pedal assembly. A valve is in a normal position that isolates the pedal assembly from the brake when in the normal mode, and is in a backup position that provides communication between the pedal assembly and the brake when in the backup mode.

    Abstract: Methods and apparatus are provided for controlling an autonomous vehicle. The control device includes an interface that establishes a connection to an autonomous vehicle, a processor that processes inputs and generates control commands to control at least one function of the autonomous vehicle, and an input arrangement with at least one control element that is assigned to a function of the autonomous vehicle. The control device transitions a controller of the autonomous vehicle to operate in at least one of a first remote operation mode and a second remote operation mode in which the autonomous vehicle is controlled by the control device, when the control device is connected to the autonomous vehicle via the interface. At least one function of a scope of functions of the autonomous vehicle is restricted in the first remote operation mode and the second remote operation mode.

    Abstract: A method for performing operations onboard a vehicle is provided. The method obtains a steering calibration command, by a computing device communicatively coupled to a steering mechanism for the vehicle; initiates execution of the steering calibration command, by the computing device via the steering mechanism; determines at least one maximum steering angle of the vehicle, based on execution of the steering calibration command, the at least one maximum steering angle being associated with a maximum potential position of the steering mechanism; identifies a zero-position center of the steering mechanism, based on the at least one maximum steering angle of the vehicle; stores the zero-position center and the at least one maximum steering angle, by the computing device, for future use; and broadcasts the zero-position center and the at least one maximum steering angle, via a Controller Area Network (CAN) bus of the vehicle, by the communication device.

    Abstract: A vehicle includes a plurality of brake assemblies configured to control braking of a respective wheel of the vehicle. The brake assemblies includes a first brake assembly integrated with a smart actuator unit including a first actuator controller and a first electro-mechanical actuator that is configured to adjust a brake force applied to a first wheel coupled to the first brake assembly. A second brake assembly excludes an actuator controller and has installed therein a second electro-mechanical actuator that is configured to adjust a brake force applied to a second wheel coupled to the second brake assembly. At least one electronic actuator driver unit is remotely located from the first and second brake assemblies, and is configured to output a high-power signal that drives the first and second electro-mechanical actuators in response to receiving a digital command signal from the first actuator controller.

    Abstract: A vehicle with a fault tolerant electronic brake-by-wire (BBW) system includes a plurality of brake assemblies that control braking of a respective wheel of the vehicle. The brake assemblies include a first brake assembly and a second brake assembly. The first brake assembly is integrated with at least one enhanced brake actuator assembly including a first electronic actuator driver circuit in signal communication with a first electro-mechanical actuator. The first brake assembly is configured to adjust a brake force applied to a first wheel of the vehicle. The second brake assembly is integrated with at least one enhanced smart brake actuator assembly including a first actuator controller in signal communication with a second electronic actuator driver circuit. The second electronic actuator driver circuit is in signal communication with a second electro-mechanical actuator that is configured to adjust a brake force applied to a second wheel of the vehicle.
