摘要： A steering locking system is provided for a motor vehicle that includes a pin, a locking disc to receive the pin, an actuation device, and a control unit. The actuation device is configured to control movement of the pin. The control unit is configured to control rotation of the locking disc and movement of the pin via the actuation device. Further, the control unit is configured to permit movement of the pin into the pocket after the occurrence of a predetermined event. The steering locking system can further include a motor operatively associated with the locking disc. The control unit may be configured to control the motor at a first power level to maintain the motor in a state of readiness and to control the motor at a second power level, different from the first power level, when the locking system detects a torque applied to the steering system.

摘要： A computer includes a processor and a memory storing instructions executable by the processor to determine at least one of a vehicle pitch or a longitudinal center of gravity from data measured while deactivating a first brake for a first axle and applying a second brake for a second axle, and operate the vehicle based on the at least one of vehicle pitch or longitudinal center of gravity. The instructions may further include to determine a vehicle weight from the data, and operate the vehicle based on the vehicle weight.

摘要： A computer includes a processor and a memory storing processor-executable instructions. The processor is programmed to determine a deviation between a predicted value and one of a sensed steering angle and a sensed steering torque of a vehicle, output a service request in response to the deviation exceeding a first threshold, and perform a minimal risk condition in response to the deviation exceeding a second threshold.

摘要： A vehicle implements a steering anti-catch (SAC) algorithm that reduces a superimposition angle added to the steering wheel angle in order to reduce occurrence of steering catch. The superimposition angle may be determined according to an AFS system. The reduction of the superimposition angle according to the SAC algorithm is amplified when the driver is steering away from a center position, the vehicle speed is below a threshold, and a voltage for powering the power steering system is below a threshold. The amount by which the superimposition angle is reduced may be limited to a maximum reduction and may be subject to a limit in its rate of change as well.

摘要： A method for estimating steering assistance provided by a power steering system of a vehicle may include correlating an internal torque applied by an adaptive steering system of the vehicle with an external torque applied to a steering assembly of the vehicle. The method may also include estimating the steering assistance based on the correlation.

摘要： A vehicle includes an engine configured to auto stop and auto start. The vehicle includes an active front steering system with an electric actuator. A controller operates the electric actuator at a current limit that is less than a requested current of the electric actuator in response to a request to change a steering ratio by an amount that results in the requested current being greater than the current limit during an engine auto stop event. The current limit may decrease from the requested current to a predetermined limit after transitioning to the engine auto stop event. The current limit may increase from the predetermined limit to the requested current after transitioning from the engine auto stop event.

摘要： A system for correcting steering wheel angle errors of a motor vehicle of the present disclosure may include a steering wheel angle sensor, an actuator angle sensor, and at least one of a wheel speed sensor and a lateral acceleration sensor. The system may further include a controller configured to receive signals from the steering wheel angle sensor, actuator angle sensor, and at least one of the wheel speed sensor and lateral acceleration sensor. The controller may be configured to calculate a correction angle based on the signals, and adjust a steering wheel angle of a steering wheel, as observed by a driver of the motor vehicle, based on the correction angle.
