Driverless automobile ABS detection bench with weighing function

Abstract

The invention discloses a driverless automobile ABS detection table with a weighing function. The driverless automobile ABS detection table comprises two roller set assemblies corresponding to front and rear wheels of an automobile respectively, two roller set racks used for installing the roller set assemblies respectively, and a weighing instrument used for detecting various load information ofthe wheels. Each roller assembly comprises two roller groups which are symmetrically arranged and respectively correspond to a single wheel; the weighing instrument comprises weighing platforms whichrespectively correspond to the single wheels and are used for detecting the load of the single wheels, and each weighing platform is respectively arranged at the front end of each roller group along the vehicle entering direction and is fixedly connected with a roller group rack. When the braking performance of the vehicle is measured, the vehicle servicing mass, the left and right wheel loads andthe whole vehicle axle load can be reflected, so that the ABS braking effect and the ABS control strategy under different vehicle quantity loads can be tested conveniently.

Description

technical field [0001] The invention relates to the field of motor vehicle testing equipment, in particular to an unmanned vehicle ABS testing platform with a weighing function. Background technique [0002] In the prior art, as the technology of unmanned vehicles continues to jump into people's sight, its safety has attracted people's attention. The braking performance of unmanned vehicles is one of the main performances of unmanned vehicles. An important guarantee for safe driving. During the braking process, the ABS system of unmanned vehicles can automatically adjust the braking process according to the vehicle speed and tire slip rate to achieve the best braking effect. Therefore, it is necessary to test the braking performance of unmanned vehicles equipped with ABS. A problem that needs to be solved at present. The change of vehicle load on the shape of the tire and the adhesion coefficient of the tire to the ground directly affect the braking effect of the driverles...

AI Technical Summary

Problems solved by technology

[0003] In order to reflect the ABS braking effect and ABS control strategy under different vehicle loads, it is necessary to detect the vehicle load synchronously when testing the ABS braking performance of unmanned vehicles, so as to make the ABS bench test items of unmanned vehicles more perfect, but the patent Document CN204115838U discloses an unmanned vehicle axle load and brake compound inspection platform, which is respectively fixed with four weighing sensors on the four corners of the braking platform frame, but since the four weighing sensors are all arranged on the On the frame of the moving table, that is to say, it measures the overall axle load, which cannot effectively reflect the correlation between a single wheel load and braking, which greatly limits the test range
