Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a vehicle diagnostic method, system, device, and storage medium based on a Bluetooth gateway. Background Technology

[0002] Pure electric buses are powered by onboard power supplies. The various control units primarily form a network using CAN communication, adhering to agreed-upon protocols for information transmission. Simultaneously, each component also sends out fault information according to the protocol based on its own status. When troubleshooting, appropriate diagnostic equipment or a computer connected to a CAN data analyzer is required to read and analyze the data.

[0003] This diagnostic method has the following drawbacks:

[0004] 1. Using specialized diagnostic equipment or computers for diagnosis is not widely adopted. In terms of production debugging or after-sales maintenance, it is costly to equip each person with a diagnostic device or computer. In addition, the diagnostic method of connecting the computer to the CAN data analyzer and then connecting the CAN data analyzer to the vehicle's OBD diagnostic port is inconvenient to carry and operate.

[0005] 2. When vehicle components form multiple network channels, a computer connected to a CAN data analyzer can only obtain information from one channel. To obtain information from other channels, the CAN data analyzer needs to be connected to other channels, making channel switching inconvenient. Summary of the Invention

[0006] Therefore, it is necessary to provide a vehicle diagnostic method, system, device, and storage medium based on a Bluetooth gateway to address the aforementioned technical problems.

[0007] In a first aspect, embodiments of the present invention provide a vehicle diagnostic method based on a Bluetooth gateway, comprising the following steps:

[0008] The vehicle's Bluetooth gateway is electrically connected to the data acquisition modules of various vehicle components, and the Bluetooth gateway is used as the CAN communication gateway for the entire vehicle.

[0009] When the Bluetooth function activation switch connected to the Bluetooth gateway is turned on, the Bluetooth gateway and the vehicle's handheld mobile device are paired and connected via Bluetooth.

[0014] Furthermore, by using the handheld mobile device to analyze data from various vehicle components, abnormal data conditions can be identified, and vehicle fault diagnosis can be completed, including:

[0015] After the handheld mobile device establishes a Bluetooth connection with the Bluetooth gateway, when the baud rate and corresponding CAN channel are set on the APP of the handheld mobile device and the configuration command is sent to the Bluetooth gateway via Bluetooth, the Bluetooth gateway will also generate a verification command to the handheld mobile device.

[0016] The handheld mobile device calculates a feedback value and sends it to the Bluetooth gateway according to the verification protocol agreed upon with the Bluetooth gateway.

[0017] When the Bluetooth gateway recognizes that the feedback result is consistent with the preset calculation, it begins to transmit the vehicle data information to the handheld mobile device. The APP on the handheld mobile device parses the raw data according to the preset rules to obtain the actual physical value.
