摘要： A vehicle includes an adaptive front steering system including an assist motor that provides an overlay angle superimposed on a steering wheel angle. External torque to the assist motor is estimated by a controller and evaluated to determine whether it is the result of an external disturbance. If so, the controller evaluates whether the external disturbance is a road disturbance, such as by determining that road wheel speed varied from the vehicle speed or that an impact site is present in outputs of external sensors of the vehicle. If a road disturbance is determined to have occurred, compliance may be introduced in order to reduce the transmission of torque to the steering wheel. Compliance may be introduced by adjusting current to the assist motor, a target angle to the assist motor, reducing gain in the control system for the assist motor, or shorting leads of the assist motor.

摘要： A computer is programmed to determine a trajectory of a first vehicle. The computer is programmed to determine whether a second vehicle blocks the trajectory. Upon such determination, the computer sends an instruction to the second vehicle to adjust the second vehicle speed. The computer is programmed to determine the instruction based on the determined trajectory of the first vehicle, a second vehicle location, and a second vehicle speed.

摘要： A steering system includes an electric motor drivably coupled to a steering column, and a computer communicatively coupled to the electric motor. The computer is programmed to isolate a nibble signal in data representing a torque of the steering column, and instruct the electric motor to output a motor torque based on the nibble signal shifted by a phase shift, the phase shift based on a vehicle-wheel frequency.

摘要： Methods and apparatus for controlling steering nibble in position controlled steering systems are described. A controller is to determine actuator angle data based on steering wheel angle data associated with a steering wheel. The controller is also to determine nibble control angle data based on the steering wheel angle data. The controller is also to determine adjusted actuator angle data based on the actuator angle data and the nibble control angle data. The controller is also to generate a control signal based on the adjusted actuator angle data to apply a torque via an actuator of a position controlled steering system.

摘要： A system for estimating torque in a locked vehicle system may include a locking mechanism comprising a stiff material. The system may further include a controller configured to estimate an amount of torque in the locked vehicle system based on a deformation of the stiff material.

摘要： A vehicle includes a steering wheel and at least one road wheel. The steering wheel is rotatably connected to a steering-wheel actuator, and the at least one road wheel is movably connected to a steering system. A controller is in communication with the steering system and the steering-wheel actuator. The controller is programmed to determine a steering-wheel angle based on a road-wheel angle, an operation mode, and a steering-compensation type; and to instruct the steering-wheel actuator to rotate the steering wheel according to the steering-wheel angle.
