Description

[0002] During vehicle development and testing, based on the vehicle status, controller version and other preparation work at different stages, the static current test results of various vehicle controllers may sometimes show that the static current exceeds the preset threshold. In order to locate the abnormal part (that is, locate the abnormal controller), R&D personnel are required to separately check the controller connected to the positive pole of the battery in the vehicle to determine which specific controller or controllers have abnormal static current, resulting in the vehicle static current exceeding the standard.

[0048] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] The vehicle static current abnormal part positioning method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. The positioning device 104 obtains the total static current value of the target vehicle 102; wherein the total static current value refers to the sum of the static current values ​​of each controller connected to the positive electrode of the battery of the target vehicle. When the total static current value is greater than the total value threshold, the positioning device 104 determines the controller in the target vehicle that is in an abnormal state based on the static current values ​​of each controller.

[0050] The target vehicle refers to the vehicle that needs to locate the abnormal parts.

[0051] The controller refers to various controllers connected to the positive pole of the battery of the target vehicle, including at least one or a combination of two or more of the various devices such as air conditioning controller, switch controller, lighting controller, power amplifier, panoramic audio controller, battery sensor, cooling fan controller, body controller, rain sensor, radar sensor, door controller and seat controller.

[0052] The positioning device can be an independent device or a logical device in the vehicle controller. It can be an existing device or a self-developed device.

[0053] In one embodiment, if Figure 2 As shown, a method for locating abnormal static current components of a vehicle is provided, and the method is applied to Figure 1 Take the positioning device in as an example to illustrate. Figure 2 As shown, the following steps are included:

[0054] S201, obtaining the total static current value of the target vehicle.

[0055] The target vehicle refers to the vehicle for which abnormal parts positioning is required. The total static current value refers to the sum of the static current values ​​of each controller connected to the positive electrode of the battery of the target vehicle. The battery refers to the battery on the target vehicle. The static current value refers to the current value of the static current of each controller.

[0056] Optionally, in this embodiment, based on the communication gateway, the static current value of each controller of the target vehicle is obtained, and the static current value of each controller is summed to obtain the total static current value of the target vehicle.

[0057] In this embodiment, an optional implementation method for obtaining the static current value of each controller of the target vehicle based on the communication gateway is that the communication gateway is wirelessly connected to a collector on the target vehicle, and the collector is used to collect the static current value of each controller of the target vehicle in real time or periodically.

[0058] In this embodiment, another optional implementation method for obtaining the static current value of each controller of the target vehicle based on the communication gateway is that each controller uploads the corresponding static current value to the communication gateway in real time or periodically. After the communication gateway summarizes the static current value of each controller, it sends the static current value of each controller to the positioning device.

[0060] The abnormal state refers to the state of the controller when the static current value is greater than the static current threshold.

[0061] Optionally, in this embodiment, the total static current value is compared with the total value threshold. If the total static current value is less than the total value threshold, the subsequent process is not executed, indicating that the working status of each controller of the target vehicle is normal. If the total static current value is greater than the total value threshold, the controller in the target vehicle that is in an abnormal state is determined based on the static current value of each controller.

When the total static current value is greater than the total value threshold, the controller in the target vehicle that is in an abnormal state is determined based on the static current value of each controller. Compared with the prior art, the present application adds the necessity of confirming abnormal parts, and the abnormal parts are located only when the total static current value is greater than the total value threshold. The present application can automatically collect the static current value of each controller, and determine the controller in the target vehicle that is in an abnormal state based on the static current value of each controller. Compared with the traditional method of locating abnormal parts by manually pulling out the fuses one by one, the present application not only greatly saves manpower investment, but also locates more accurately and efficiently.
