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.
A flat-belt type VTEHIL test bench for commercial vehicles, comprising a main bench body (2) and a bench test system, the main bench body (2) mounted inside a foundation (1), wherein the main bench body (2) comprises a main bench frame (8), a bench cover (14), front axle flat-belt assemblies (9) and rear axle flat-belt assemblies (10), each front axle flat-belt assembly (9) provided therein with a fixed plate (11), a rotary disc (12) and a limiting mechanism (13), each rear axle flat-belt assembly (10) comprising a flat belt (20) and flat belt pulleys (16) both disposed within the flat belt at opposing ends thereof, wherein the foundation (1) defines a sector-shaped mounting depression (3) in which the main bench body (2) is mounted, with an iron floor (4) being arranged under the main bench body (2) and a pivotal support base (5) connecting the iron floor (4) to the main bench body (2), so that a top surface of the main bench body (2) is flush with a floor surface, the mounting depression (3) provided at a front edge thereof with an arc-shaped guide track (6), the main bench body (2) provided at a front end thereof with guide wheels engaging the arc-shaped guide track (6), and wherein the main bench body (2) is configured to support thereon a commercial vehicle under test with front wheels resting on the front axle flat-belt assemblies (9) so that the front axle flat-belt assemblies (9) are able to turn independently with the steer wheels and rear wheels resting on the rear axle flat-belt assemblies (10).
A flat-belt type VTEHIL test bench for commercial vehicles, comprising a main bench body (2), wherein the main bench body (2) comprises a main bench frame (8) having a front section where a pair of front axle flat-belt assemblies (9) is arranged and a rear section where a pair of rear axle flat-belt assemblies (10) is arranged,
