摘要： Disclosed in this invention is a flat-belt type VTEHIL test bench for commercial vehicles, including a main bench body and a bench test system. The main bench body is mounted inside a foundation and includes a main bench frame, a bench cover, front axle flat-belt assemblies and rear axle flat-belt assemblies. Each front axle flat-belt assembly is provided therein with a fixed plate, a rotary disc and a limiting mechanism. Each rear axle flat-belt assembly includes a flat belt and flat belt pulleys disposed both within the flat belt at opposing ends thereof. The foundation defines a sector-shaped mounting depression in which the main bench body is mounted, and an iron floor is arranged under the main bench body. This invention can better simulate actual driving surfaces and accommodate two-axle, three-axle, four-axle and other types of trucks or tractors. The test bench is able to test unmanned driving capabilities of intelligent commercial vehicles by allowing them to take lane changing, turning, braking and other driving actions in simulated setups and providing them with various traffic scenarios created with simulated traffic participants.

摘要： A comprehensive performance test system for Automated Driving Vehicles related to the technical field of vehicle testing equipment. It solves the technical problem of testing Automated Driving Vehicles. The system comprises a base platform, a lateral moving platform mounted on the base platform, and a rotary platform mounted on the lateral moving platform; There are two front wheels' brackets in the front of the rotary platform which can slide left and right, and two front wheel track adjustment mechanisms to control the movement of left and right sliding of two front wheels' brackets; There are two rear wheels' brackets on the rear of the rotary platform which can slide front and back, and two wheelbase adjustment mechanisms to control the movement of front and rear sliding of two rear wheels' brackets. Each front wheel bracket is equipped with a dynamometer bracket which can rotate horizontally, and each front wheel dynamometer bracket is equipped with a rotary dynamometer and a motor for driving the rotation of the front wheel dynamometer. Each rear wheel bracket is equipped with a rear wheel rotary dynamometer and a load motor for driving the rotation of the real wheel rotary dynamometer. The system provided by the invention can test the longitudinal and lateral performance of Automated Driving Vehicles.
