Embodiment Construction

[0008] A steer-by-wire test bench includes a simulated load 10 for simulating the lateral resistance of the ground when the vehicle is turned, and the test bench also includes a steering action input end for placing a steering assembly 20 and a connecting The steering action input end and the transmission unit 30 of the simulated load, the simulated load 10 is two and coaxially separated and arranged on both sides of the output end of the transmission unit 30, the test bench also includes sensors, and the transmission unit 30 drives the simulated load. The load 10 generates axial serial movement along the transmission shaft of the simulated load 10, and the sensor acquires force and / or displacement information at the simulated load 10, such as Figure 1-2 shown.

[0009] As a further preferred version of the present invention: as Figure 1-2 As shown, the simulated load 10 and its transmission shaft form a dumbbell structure as a whole, the transmission unit 30 is a reduction...

Abstract

The invention belongs to the field of automobile steering control, in particular to a platform frame used for steering-by-wire experiments, which comprises simulation loads used for simulating ground lateral resistance received by an automobile when the automobile changes direction. The platform frame for experiments further comprises a steering action input end used for placing a steering assembly and a transmission unit used for connecting the steering action input end and the simulation loads. The two simulation loads are coaxially arranged on two sides of the output end of the transmission unit. The platform frame for experiments further comprises a sensor, the transmission unit drives the simulation loads to generate axial movement along a transmission shaft of the simulation loads, and the sensor acquires force and / or displacement information at the position of the simulation loads. The parts are integrated on the same platform frame, and the parts are compact in arrangement, simple in structure and easy to process. After set information is input into the steering action input end, axial movement is generated at the simulation loads, and simultaneously the sensor records the movement displacement and stressed information in proper time. The platform frame is sensitive and reliable in integral action and convenient to use.

Description

technical field [0001] The invention belongs to the field of steering control of automobiles, and in particular relates to a test stand for steering by wire. Background technique [0002] The steering system of automobiles has gone through various stages such as mechanical, traditional hydraulic assist, electro-hydraulic assist and electric assist. Steering by wire is an inevitable development trend of automatic steering control of automobiles. Before the steer-by-wire system is installed, its hardware and software must be fully tested on the test bench, so as to ensure its good adjustability through continuous debugging and improvement. However, the existing test benches are often too complicated in structure and high in cost. How to develop an effective, simple and reliable steer-by-wire test bench is an unresolved problem in the field of existing automotive steering systems. technical challenge. Contents of the invention [0003] The object of the present invention is...
