Abstract: Disclosed are a method and an apparatus of denoising, and the method includes: receiving a first voice signal picked up by a microphone; if it is detected, with the first voice signal, that a sensor is in an operation state, subtracting an interference noise signal from the first voice signal to obtain a first voice signal with the interference removed therefrom, where the interference noise signal is an interference noise signal generated with regard to the microphone during an operation of the sensor, and the sensor and the microphone are packaged in one module; and outputting the first voice signal with the interference removed therefrom. By implementing the solution provided in the present disclosure, interference in a signal collected by a microphone when the microphone and a sensor in a module operate together is reduced and the small size of the module, packaged with the microphone and sensor, is guaranteed.

Abstract: A controller for a power steering system estimates rack force and its derivative, such as based on lateral acceleration, yaw rate, vehicle speed, or other parameters. A control torque is calculated based on the rack force, its derivative, and the vehicle speed and is summed with an input torque from the driver to determine an amount of assist torque to provide. The control torque may be a shape function that has a sign determined by the sign of the derivative and a magnitude that decreases from a maximal value with increase in the magnitude of the rack force. The maximal value may be determined according to vehicle speed.
