摘要： A computer includes a processor and a memory storing instructions executable by the processor to determine a learned clear vision offset based on a currently calculated clear vision offset and a previously stored clear vision offset, and steer a steer-by-wire system of a vehicle while correcting a steering angle by a lesser value of the learned clear vision offset and a maximum correctable offset.

摘要： A system includes a computer programmed to specify, while a vehicle is turning, a feedback torque based on a steering torque applied to a steering rack and a difference between a desired angle and an actual angle of vehicle steerable wheels. The computer is further programmed to actuate feedback torque to a vehicle steering wheel.

摘要： Methods and apparatus to reduce noise and vibration in a hybrid hydraulic power steering system are disclosed. A method includes receiving sensor data from sensors of a vehicle and mapping the sensor data to filter coefficients. The method further includes generating a torque demand based on an input of the filter coefficients into a polynomial filter and tuning at least one of a torque assistance or a steering damping of an assisted steering system of the vehicle based on the torque demand.

摘要： Methods, apparatus, systems and articles of manufacture are disclosed to improve electronic power assisted steering in a vehicle. An example apparatus includes memory and a processor to execute instructions to determine a steering column torque associated with a steering column of an electronic power assisted steering (EPAS) system in a vehicle, determine a steering column torque derivative based on a derivative of the steering column torque, determine a compliance compensation torque based on the steering column torque and the steering column torque derivative, and adjust a steering response of the steering column based on the compliance compensation torque.

摘要： A system includes a torque overlay device having an input shaft and an output shaft coupled to the input shaft. The system includes a steering wheel coupled to the input shaft. The system includes a processor and a memory storing instructions executable by the processor to detect a torque applied to the input shaft and to actuate the torque overlay device to provide torque to the output shaft in a direction opposite the torque applied to the input shaft.
