Embodiment Construction

[0035] The present invention is described in further detail below in conjunction with accompanying drawing:

[0036] A driving robot system for vehicle testing, including a control unit, a positioning and navigation unit connected to the control unit, a trajectory tracking unit, a mechanical execution component control unit and a remote data transmission unit;

[0037] The positioning and navigation unit is used to obtain the longitude and latitude position information of the vehicle in the global coordinate system and the heading information of the vehicle in real time, and transmit the obtained information to the control unit;

[0038] The trajectory tracking unit is used for vehicle motion trajectory tracking, and the tracking trajectory information is transmitted to the control unit;

[0039] The control unit of the mechanical execution part is connected to the control unit, and executes the control signal transmitted by the control unit;

[0040] The remote data transmis...

Abstract

The invention discloses a robot driving system for vehicle testing and a control method. High-precision following control of the robot driving system to a preset traveling trajectory is achieved through a trajectory tracking unit, a vehicle runs by following a preset target trajectory by adjusting front wheel turning angles and running speed of the vehicle, accordingly a target instruction of thehigh-precision trajectory tracking unit is issued to the tested vehicle, and movement control of the vehicle is achieved. A remote data transmission unit is used for achieving real-time full-duplex communication between the tested vehicle and a monitoring center, the monitoring center can issue an instruction at any time to control the tested vehicle, the robot driving system in the vehicle acquires vehicle condition information of the tested vehicle in real time, and remote state monitoring of the tested vehicle is achieved. By adopting the way integrating a positioning technology and a high-precision trajectory tracking technology, automatic testing of the tested vehicle in a closed test site is achieved, and the robot driving system is high in control precision, good in repeatability and strong in durability.

Description

technical field [0001] The invention relates to the technical field of automatic driving of vehicles, in particular to a driving robot system and control method for vehicle testing. Background technique [0002] According to the requirements of national laws and regulations, all vehicles must go through strict type testing and testing before leaving the factory for sale. A very important part of the testing is to test the vehicle performance in a closed automobile proving ground. In the closed automobile proving ground, the tested vehicles pass through a variety of typical road surfaces as required, such as Belgian roads, wading roads, etc. At present, in this test link, the human driver is still used to drive the tested vehicle through the above-mentioned road section, and obtain the evaluation index of vehicle performance through repeated driving for a long time. Manual driving test has defects such as high labor cost, incapable of full-time testing, and greater physical ...
