摘要： Method, system and non-transitory computer-readable medium for fail-safe performance of a lane centering system. An electrical power steering (EPS) system of a vehicle is monitored for a failure and operation of the lane centering system is switched to a differential braking controller to output differential braking commands to a differential breaking system upon determining that a failure of the EPS system has occurred, where the output braking commands direct the differential braking system to apply force a brake for a wheel of vehicle, such by the applied braking force the vehicle follows a desired path determined for a lane centering operation.

摘要： A method, for controlling direction of a vehicle as desired in connection with operation of an autonomous driving maneuver using selectively, independently and/or in combination, multiple electrical park brakes (EPBs) and multiple hydraulic brakes (HBs). The method includes determining a total brake force needed for redirecting the vehicle in a pre-determined manner, and determining whether an applicable EPB can provide the total brake force needed. The method further includes providing, if it is determined that the applicable EPB can provide the total brake force needed, a brake command instructing the applicable EPB to apply the total brake force. The method also includes determining, if it is determined that the EPB is alone insufficient, an optimal fusion of the EPBs and the HBs, including two front and two rear HBs, two rear EPBs, and in some embodiments, also two front EPBs.

摘要： Motor-generators are incorporated in front wheels and drive the front wheels, respectively. An ECU determines whether or not a steering apparatus including a steering actuator, a tie rod and a steering angle sensor has failed, based on an operation angle of a steering wheel from a steering wheel angle sensor and a steering angle of the front wheels from the steering angle sensor. When the ECU determines that the steering apparatus has failed, the ECU provides torque difference for a torque instruction for the motor-generators in accordance with the operation angle of the steering wheel.

摘要： A steering system for a vehicle includes a front wheel supported for rotation about a first axis and a pivot axis transverse to the first axis and spaced inboard of a centerline of the front wheel. The front wheel is movable about the pivot axis to change direction of the vehicle. A brake coupled to the front wheel provides braking rotation of the front wheel and a controller controls operation of the brake to generate a desired braking force in a direction determined to adjust a vehicle direction.

摘要： A method for implementing directional control of a motor vehicle is disclosed. In an exemplary embodiment, the method includes determining whether a failure of a primary steering system of the motor vehicle exists. If a failure of the primary steering system exists, then a yaw moment is created on the vehicle by causing a differential longitudinal force to be applied with respect to a first wheel on one side of the vehicle and a second wheel on an opposite side of the vehicle, thereby causing the vehicle to turn in a commanded direction.
