Embodiment Construction

[0040] In order to make the purpose, technical solutions and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings.

[0041] Before explaining the starter durability test method provided herein, the apparatus performing the device's durability test method is specifically described, such as figure 1 As shown, the starter durability test device includes a starter M, an engine W, a control unit 1, and a proximity switch 2.

[0042] Wherein, the starter M is connected to the control unit 1 and the engine W, and the starter M drives the engine W to rotate under the control of the control unit 1. The proximity switch 2 is connected to the control unit 1, approaches the switch 2 to detect the rotational speed of the engine W generates a switch quantity signal, so that the control unit 1 acquires the rotational speed of the engine W according to the switch quantity signal.

[0043] The starter ...

Abstract

The invention discloses a starter durability test method and device, and relates to the technical field of automobiles, wherein the method comprises the steps: obtaining a switching value signal of aproximity switch in a second set time after an engine operates for a first set time; calculating a rotational speed of the engine based on the switching value signal; counting the starting success frequency and the starting success rate of the engine based on the rotating speed of the engine; and when the starting success frequency reaches the first threshold value and the starting success rate reaches the second threshold value, enabling the durability of the starter to be qualified. According to the starter durability test method and the device for executing the method provided by the embodiment of the invention, the accuracy of the starter durability test result can be improved.

Description

Technical field [0001] This application relates to the field of automotive technology, and in particular, to a starter durability test method and apparatus. Background technique [0002] With the development of the automotive industry, the requirements for automotive emissions and driving are more strict, and more and more vehicles are configured, and the electric energy stored by the vehicle provides energy for the startup of the engine, so that the startup Fuels in the transmitter can also be fully burned to achieve the effect of vehicle emission reduction. In order to ensure that the starter can stabilize in the whole vehicle, the durability test of the starter system is extremely important. [0003] In the relevant technique, the manual manual control start test is used to test the durability of the starter, repeat the operation of the starter operation and the stop, and the number of start-up success of the starter during the test. [0004] In the process of implementing the...
