Problems solved by technology

This kind of real vehicle road test is usually more dangerous, especially the anti-lock braking system in the development process is not perfect, and most vehicle braking tests will inevitably cause various dangerous situations during the test process, such as Sideslip, rollover, etc., causing casualties and property damage
At present, there is no corresponding device in China that allows the braking test of the anti-lock braking system of the vehicle to be completed in a static state.

Description

technical field [0001] The invention relates to a vehicle wheel speed signal device and method, in particular to a vehicle anti-lock brake system wheel speed signal real-time parameter simulation device and method. Background technique [0002] During the development of the anti-lock braking system of the vehicle, the driver must conduct a large number of real vehicle road braking tests on roads with different adhesion coefficients, and simulate braking under various conditions to determine the control of the braking system. methods and control parameters. This kind of real vehicle road test is usually more dangerous, especially the anti-lock braking system in the development process is not perfect, and most vehicle braking tests will inevitably cause various dangerous situations during the test process, such as Skidding, overturning, etc., causing casualties and property damage. At present, there is no corresponding device in China that allows the braking test of the anti...
