Abstract

The invention provides a steering control method and a steering control system of a vehicle, and relates to the field of vehicle chassis. The vehicle of the present invention includes at least one carriage, and the carriage includes at least two axles spaced in the front-rear direction. The present invention first obtains the speed of the vehicle when the vehicle starts to turn and the steering of the first axle at the front end in the running direction of the vehicle angle, the first axle is connected to the steering wheel of the vehicle, and the steering wheel is at the front end in the driving direction; then the calculation is based on the actual steering angle of the N‑1th axle in the driving direction and the current speed of the vehicle, which is adjacent to the N‑1th The target steering angle of the Nth axle behind the axle, and the steering angle of the Nth axle is adjusted according to the calculated target steering angle; wherein, N is a positive integer greater than or equal to 2. Therefore, in the present invention, through the above control strategy, each axle can be steered independently according to their respective target steering angles, thereby reducing the turning radius and sweeping area of ​​the vehicle body.

Description

technical field [0001] The invention relates to the field of vehicle chassis, in particular to a vehicle steering control method and a steering control system. Background technique [0002] With the rapid development of urbanization, the radius of people's living areas is increasing, and the demand for public travel is increasing. Therefore, there is a greater demand for public transport capacity. Modern urban transportation systems mainly include subways, rail trains and buses. [0003] Among them, subways and trams are guided by multi-cabinet hinges through the laid track, so that the vehicles can drive and stop according to the established tracks and stations. Although the transportation volume of subways and trams is large, the investment cost is huge, and the stations are fixed. Track and construction dedicated power system support. [0004] The solution to the mass transportation of buses is to use double-compartment articulated passenger cars and double-decker passe...
