Embodiment Construction

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0029] The torque compensation control method of a vehicle in a side wind scene according to an embodiment of the first aspect of the present invention will be described below with reference to the accompanying drawings. Among them, the caster angle of the vehicle will increase the sensitivity of the vehicle to the side wind, which tends to make the vehicle turn in the downwind direction. In some embodiments, the scene in which the vehicle is subjected to side wind when driving straight may be referred to as a side wind scene.

Abstract

The invention discloses a lateral wind vehicle torque compensation control method and device, an EPS system and a vehicle. The torque compensation control method comprises acquiring the current vehicle speed and the lateral wind pressure of the windward side of the vehicle; according to the lateral wind pressure, computing the lateral wind resultant force of the windward side of the vehicle; according to the lateral resultant force and the arm of force from the ground point of a steering wheel to the steering axis of the steering wheel, calculating the torque of a main pin; according to the current vehicle speed and the moment of the main pin, calculating a compensating torque; according to the compensating torque, performing steering compensation under the action of the lateral wind. According to the torque compensation control method and device, the EPS system and the vehicle, the vehicle speed and the lateral wind resultant force are taken into comprehensive consideration to accurately control the torque of the vehicle during straight driving, so that the influence of the lateral wind on the straight driving the vehicle can be reduced and the driving safety can be improved.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a torque compensation control method for a vehicle in a lateral wind scene, a torque compensation control device for a vehicle in a lateral wind scene, an EPS system and a vehicle. Background technique [0002] With the development of vehicle technology, people's requirements for vehicle safety, environmental protection, and comfort continue to increase. The rapid development of electronic technology plays an irreplaceable role in improving vehicle safety and driving stability. Among them, wheel alignment is an aspect to improve vehicle driving safety and comfort. Wheel alignment parameters include wheel camber, kingpin inclination, kingpin offset, kingpin caster, and toe angle. Wheel alignment parameters have an important impact on vehicle handling stability, steering performance, tire wear life, suspension parts and steering system parts stress. Among them, the ca...
