Test bench for evaluating intelligent driving assistance function of whole vehicle

Abstract

The invention provides a test bench for evaluating an intelligent driving assistance function of a whole vehicle. The test bench comprises a fixed frame, a rotating frame, a sliding frame, drivers, shock absorbers and a torque sensor; the fixed frame is fixed on the ground; the rotating frame is rotationally connected to one end of the fixed frame; the sliding frame is slidably connected to the rotating frame; the four drivers are erected on the fixed frame and the sliding frame in pairs, the shock absorbers are arranged on the drivers respectively, and the torque sensor is slidably connectedto the ground on one side of the rotating frame. Chutes are formed in the fixed frame and the sliding frame respectively, the length direction of the chutes is the same with the width direction of thefixed frame, and the bottoms of the shock absorbers are slidingly connected into the chutes so that spacing between the drivers is reduced. According to the test bench, a vehicle model is replaced bya real vehicle, the real condition is approached more, and the problem that a dynamic model in HIL simulation is not fine enough is overcome.

Description

technical field [0001] The invention relates to the field of automobile test equipment, in particular to a test bench used for evaluation of intelligent driving assistance functions of a complete vehicle. Background technique [0002] Intelligent assisted driving vehicle refers to equipped with advanced on-board sensors, controllers, actuators and other devices, and integrates modern communication and network technologies to realize the exchange and sharing of intelligent information between vehicles and people, vehicles, roads, clouds, etc., with complex environment perception, Functions such as intelligent decision-making and collaborative control can realize "safe, efficient, comfortable, and energy-saving" driving, and finally realize a new generation of vehicles that can replace humans to operate, and can realize optimal driving and automatic driving of the vehicle itself. [0003] Intelligent assisted driving vehicles involve more complex functions and applications, wh...

[0003] Intelligent assisted driving vehicles involve more complex functions and applications, which also make development and testing face many challenges

The working conditions are infinite. Severe and complex working conditions can be encountered but cannot be met, nor can they be reproduced, and repeated verification cannot be repeated. Then, how long will it take for the road test to verify the effectiveness and reliability of the automatic driving function under any circumstances? In addition to testing on public roads, special test and verification sites are also being built at home and abroad, but in terms of development time, cost, and flexibility, they cannot meet the development and verification needs of complex functions of intelligent assisted driving vehicles; the test evaluation of intelligent assisted driving vehicles lies in mining Hidden functional defects, so traditional car testing methods can no longer meet the requirements of intelligent assisted driving car test certification
