Problems solved by technology

The disadvantage is that once a fault occurs and needs to be diagnosed, it needs to use a special OBD diagnostic instrument in a specific place such as a 4S shop, and it is difficult to save and feed back the original data of the fault to the OEM
The disadvantage is that it is only for car factories or related departments

Embodiment Construction

[0027] see figure 1 It can be seen that the remote monitoring system for electric vehicles and hybrid vehicles includes a diagnostic protocol processing module, a storage module, a vehicle collision signal detection module, a wireless module, a vehicle wake-up control module, a vehicle positioning module, a vehicle charging monitoring, and a vehicle wake-up function module.

[0028] The diagnosis protocol processing module mainly completes the automatic reading of the fault codes of the main controllers of the vehicle and the passive execution of the background diagnosis instructions. It obtains the vehicle high-voltage battery and the status of the whole vehicle through the CAN bus application protocol, including vehicle speed, motor speed, high-voltage bus current and battery SOC, etc., and regularly stores the collected information into the SD card that comes with the terminal. At the same time, the vehicle continuously detects the fault status flags of the main controller ...

Abstract

The invention discloses a remote monitoring system for an electric car and a hybrid power car. A diagnostic protocol processing module of the system obtains the state of a car high-voltage battery and the state of the whole cars through a CAN bus application protocol, meanwhile, the failure state zone bit of a car control unit is continuously detected by the cars, and collected information is stored in a storage module at regular time. The system can remotely monitor the operating and charging state of the cars, and in addition, the failures of the cars can be automatically detected and reported. Meanwhile, the charging state of the personal electric car can be mastered in real time by an individual user through an intelligent mobile phone, a specific economical time frame can be selected to carry out charging, and charging expenses are saved.

Description

technical field [0001] The invention relates to the field of remote monitoring of electric vehicles and hybrid vehicles. Background technique [0002] In order to meet the fault diagnosis and solve after-sales maintenance problems, the current automobiles integrate the OBD diagnostic protocol in the key electronic control parts, and the vehicle fault code can be read through the special diagnostic equipment and the standard fault diagnosis protocol in the repair shop, so as to locate the vehicle current failure. The disadvantage is that once a fault occurs and needs to be diagnosed, it needs to use a special OBD diagnostic instrument in a specific place such as a 4S shop, and it is difficult to save and feed back the original data of the fault to the OEM. [0003] According to the current regulations on new energy vehicles, electric and hybrid vehicles driven by lithium batteries are in the immature stage, and a remote monitoring system must be installed to meet the real-ti...
