Method and device for obtaining minimum turning radius of vehicle

Abstract

The invention discloses a method and device for obtaining the minimum turning radius of a vehicle, and the method comprises the following steps: controlling the vehicle to carry out the minimum turning test, and obtaining a positioning signal of the vehicle in the minimum turning test process through a positioning module on the vehicle; drawing a driving track circle of the vehicle according to the positioning signal of the vehicle; and obtaining the radius of the running track circle, and obtaining the minimum turning radius of the vehicle according to the radius of the running track circle,the axle distance of the vehicle, the distance between the installation position of the positioning module and a front axle of the vehicle and the wheel distance of front wheels of the vehicle. According to the method provided by the embodiment of the invention, the requirement on the test environment is reduced, the measurement precision is high, the vehicle does not need to be greatly transformed, the test can be realized by virtue of the positioning module on the vehicle, the operation is simple, the test personnel do not need to work outside the vehicle, the manpower and material resourcesare saved, and the working feeling of the test personnel is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of the minimum turning radius of a vehicle, in particular to a method for obtaining the minimum turning radius of a vehicle, a device for obtaining the minimum turning radius of a vehicle, electronic equipment, and a computer-readable storage medium. Background technique [0002] The minimum turning radius refers to the radius of the track circle where the center of the outer steering wheel rolls on the support plane when the steering wheel is turned to the limit position and the vehicle is turning at the lowest stable speed. The ability to bend terrain or circumvent impassable obstacles, so the minimum turning radius is an important performance indicator of the vehicle. [0003] At present, the measurement of the minimum turning radius is generally realized by a sprinkler device, by sprinkling water on the wheels when the vehicle is turning, so that the wheels form a wheel motion trajectory on the g...

Problems solved by technology

[0004] However, using this measuring device to measure the minimum turning radius needs to meet at least the following conditions at the same time: (1) the test site has no precipitation and the test ground is dry; (2) the test process is rapid; (3) the tester needs to work outside the vehicle

[0005] Therefore, if the test site is rainy and / or the ground is wet and / or the test process is slow, it may cause the wheel motion trajectory to be blurred or even disappear, and it is impossible to measure the minimum turning radius. Working outside the vehicle in the environment may cause adverse reactions such as heat stroke, which will bring discomfort to the tester
