Problems solved by technology
The test of unmanned vehicles is different from the traditional vehicle test. It is necessary to build a test environment close to the real traffic scene for the vehicle to be tested. Test driving conditions and safety status
This single driving environment simulation scene is not sufficient, and cannot achieve full-road conditions, full-scenario, and full-coverage tests, so it is impossible to give a test safety estimate for unmanned vehicles
When unmanned vehicles enter the social road test in the future, it is impossible to predict whether they will be affected by special road conditions, such as bumpy road conditions, slopes, heavy vehicle loads, partial loads, etc. An unsafe state that leads to the emergence of unmanned vehicles may even cause major losses to public resources, traffic, and pedestrians

The invention provides a driverless vehicle posture simulation device, relates to the technical field of vehicle testing and solves the technical problem about testing of a driverless vehicle. The device comprises a bearing base and a bearing platform, wherein a lifting control screw rod is vertically arranged on the bearing base, a load control motor used for driving the lifting control screw rodto rotate and a movable rack capable of sliding vertically are arranged on the bearing base, and the movable rack is in threaded connection with the lifting control screw rod; two posture control electric cylinders are arranged on the movable rack, and load sensors are mounted at the tops of output shafts of the two posture control electric cylinders; three universal joints distributed triangularly are arranged on the bearing platform, one universal joints is connected with the top end of the movable rack, and the other two universal joints are connected with the load sensors at the tops of the output shafts of the two posture control electric cylinders respectively. The device can carry out testing safety estimation on the driverless vehicle.
Description
technical field [0001] The invention relates to vehicle testing technology, in particular to the technology of an unmanned vehicle attitude simulation device. Background technique [0002] At present, vehicle performance tests on the market generally only pass real vehicle road tests, or tests in closed venues. The test of unmanned vehicles is different from the traditional vehicle test. It is necessary to build a test environment close to the real traffic scene for the vehicle to be tested. Driving conditions and safety status are tested. This single driving environment simulation scenario is insufficient, and cannot achieve full-road conditions, full-scenario, and full-coverage testing, so it is impossible to give a test safety estimate for unmanned vehicles. When unmanned vehicles enter the social road test in the future, it is impossible to predict whether they will be affected by special road conditions, such as bumpy road conditions, slopes, heavy vehicle loads, part...
