Abstract

The invention provides a vehicle steering control method and system, and relates to the field of vehicle chassis. The vehicle comprises at least one compartment, the compartment comprises at least two axles arranged at intervals in the front-back direction, the vehicle speed of the vehicle and the steering angle of the first axle located at the foremost end in the driving direction of the vehicle are obtained when the vehicle starts to steer, and the first axle is connected with a steering wheel of the vehicle; the steering wheel is located at the front end in the driving direction; then, according to the actual steering angle of the N-1th axle in the driving direction and the current vehicle speed of the vehicle, the target steering angle of the Nth axle adjacently located behind the N-1th axle is calculated, 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, according to the control strategy, each shaft can independently steer according to the respective target steering angle, so that the turning radius and the sweeping area of the vehicle body can be reduced.

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...
