An eps-based steering assist mode switching system and method

Abstract

The invention discloses an EPS based power-assisted steering mode switching system. The EPS based power-assisted steering mode switching system comprises an EPS electric power-assisted steering systemand a display screen which is in CAN communication with the EPS electric power-assisted steering system, wherein the display screen is equipped with a power assisting mode selecting module and a modeswitching display module; a safety switching monitoring program is configured in the EPS electric power-assisted steering system; the safety switching monitoring program can be used for feeding backpower-assisted steering mode results of the EPS electric power-assisted steering system to the display screen; the power assisting mode selecting module is used for displaying alternative power assisting modes, and sending corresponding message to the EPS electric power-assisted steering system when certain power assisting mode is selected; and the mode switching display module is used for receiving power-assisted steering mode switching results fed back by the safe switching monitoring program and displaying the corresponding switching results. The invention further discloses an EPS based power-assisted steering mode switching method which adopts the EPS based power-assisted steering mode switching system. The power-assisted steering switching safety can be improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a steering assist mode switching system and a steering assist mode switching method. Background technique [0002] EPS (Electric Power Steering) refers to the power steering system that relies on the motor to provide auxiliary torque, that is, the electric power steering system. Most of the current EPS systems only provide one kind of steering force, but the steering force requirements of different drivers are not the same, especially the steering force requirements of male drivers and female drivers are significantly different. Female drivers generally hope that the steering force of the vehicle should be lighter, while for male drivers, if the steering force is too small, they will feel that the vehicle's handling stability is poor and their driving confidence is insufficient. Therefore, a single EPS power steering can no longer meet the demand, and EFPS is required to support the o...
