Document Type and Number:
WIPO Patent Application WO/2023/005615
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of vehicles. Disclosed are a test system and test method for a regenerative braking operating condition of a vehicle, and a device and a storage medium. The test system comprises a brake caliper, an ESC, an electronic booster, an actuating cylinder, a pressure sensor and a test controller, wherein the test controller is electrically connected to the ESC, the electronic booster, the actuating cylinder and the pressure sensor, and is used for reading operating condition states of the ESC and the electronic booster in real time; one end of the ESC is connected to the brake caliper, and the other end of the ESC is connected to the electronic booster; and the electronic booster is arranged on the actuating cylinder, and the actuating cylinder pushes a push rod of the electronic booster to move forward. By means of the test method in the present invention, on the basis of the theory of an orthogonal method, a typical driving mode used when a boosting degradation event occurs can be automatically found, and an automatic bench test is performed within a small range under a driving mode condition, thereby greatly saving time. In the present invention, the step of checking whether regenerative braking is started is added, so that it can be ensured that the whole course of a test process is performed under the condition that the regenerative braking is started.
