    摘要: Steer-by-wire steering systems for vehicles and related methods are described herein. An example steer-by-wire steering system includes a steering wheel angle sensor to detect a current steering wheel angle (α) of a steering wheel of the motor vehicle, a steering actuator to generate a variable steering torque on a steerable wheel of the motor vehicle, a steering angle sensor to detect a current steering angle (β) of the steerable wheel, and a steer-by-wire controller to process signals from the steering wheel angle sensor and the steering angle sensor and control the steering actuator based on the signals. The steer-by-wire controller is configured to vary a transmission ratio between a change in the steering wheel angle (α) and a change in the steering angle (β).

    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: Stabilization method and system for performing dynamic chassis control in a vehicle. An electronic stability control (ESC) includes an ESC sensor set; at least one chassis actuator; and a dynamic controller operably connected to at the least one chassis actuator. The ESC sensor set generates one or more sensor fault signals. Then, the method employs a dynamic controller to evaluate the signals corresponding to the sensor fault at least after a first fast fault signal, or a second slow fault signal. If the first fast fault signal is detected, the dynamic controller generates a signal for at least one of partially or completely temporarily switching off the at least one chassis actuator, while maintaining ESC in an active state. Conversely, if the second slow fault signal is detected, the dynamic controller generates a signal for temporarily switching off the ESC.

    摘要: A steer-by-wire system for a land vehicle, having a steering wheel, a feedback actuator, a detection device equipped to detect a driver's intention to enter the vehicle and/or a driver's intention to exit the vehicle, and an electronic control system, which, following detection of the intention to enter the vehicle and/or the intention to exit the vehicle controls the feedback actuator to hold the steering wheel in a predetermined rotational position by generating a holding torque. When an actuating torque which exceeds the holding torque is applied manually to the steering wheel and the steering wheel is rotated out of the predetermined rotational position, the electronic control system continuously approximates a turning angle of the predetermined rotational position to a turning angle of a current rotational position of the steering wheel using a specified time-based adjustment function based on a difference between the actuating torque and the holding torque.

    摘要: A system for a vehicle includes a gear and a plate fixed to the gear. The gear is driving by a motor for providing relative rotation between a steering wheel and steering shaft of the vehicle in an adaptive front steering system. The system includes a solenoid including a coil and a pin moveable relative to the coil to engage the plate based on a signal. A sensor is configured to detect a change in current through the coil associated with initial movement of the pin relative to the coil. The system includes a controller programmed to change the duty cycle signal in response to the change in current to slow movement of the pin to reduce or eliminate a clicking noise associated with the pin seating in an extended position or retracted position.

    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.
