Problems solved by technology

However, this kind of steering control belongs to post-event control to a certain extent. It is the attitude correction of the whole vehicle made by the electronic stability control system ESP according to the detected response of the whole vehicle. The electronic stability control system (ESP) cannot completely and timely correct the attitude of the vehicle, and it will still cause the vehicle to hit other vehicles or objects such as high-speed guardrails

Abstract

The invention discloses a vehicle power-assisted steering control method and device, equipment and a storage medium. The vehicle power-assisted steering control method comprises the steps that a firstrelation table is queried in response to received steering input information, and thus driver steering intention corresponding to the steering input information is obtained; the first relation tableis used for storing the corresponding relation of the steering input information and the driver steering intention; before an electronic stability control module is involved, output torque of a steering motor is adjusted according to a preset control strategy and according to the driver steering intention; and after the electronic stability control module is involved, the output torque of the steering motor is adjusted according to received vehicle response parameters. Improper steering operation of the driver can be limited to a certain extent, and the stability and safety of a vehicle duringhigh-speed travelling are significantly improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving, in particular to a vehicle steering assist control method, device, equipment and storage medium. Background technique [0002] Vehicles in the prior art are usually equipped with an electric power steering system EPS and an electronic stability control system ESP, which provide corresponding power assistance for vehicle steering and body stability control during braking. [0003] The electric power steering system EPS provides corresponding power assistance according to the ground friction, and at the same time, it will appropriately reduce the power assistance with the increase of vehicle speed to increase high-speed stability. Some vehicles also have the lane keeping function LKA. In the automatic cruise mode, it can provide lateral force control to prevent the vehicle from lane departure, but the above functions have nothing to do with the steering assist control under the ...
