Problems solved by technology
[0003] In the above technical solution, the intelligent vehicle-mounted terminal needs to periodically read the fault codes, which occupies the sending and receiving resources of the intelligent vehicle-mounted terminal. Due to the periodic query, it is easy to miss the statistics of some occasional faults; and at the same time, periodic query will give The vehicle network brings a certain load, which can easily affect the normal operation of the vehicle network

Embodiment Construction
[0020] Embodiments of the vehicle fault code reading method, device and vehicle fault statistics system of the present invention will be described below in conjunction with the accompanying drawings.
[0021] The scheme of the embodiment of the vehicle fault code reading method of the present invention can be applied to the intelligent vehicle terminal equipment, refer to figure 1 , figure 1 It is a schematic diagram of the on-board intelligent system. The intelligent on-board terminal is connected to multiple on-board control systems through the in-vehicle network, such as CAN bus, and communicates with the background server through the Internet. The intelligent vehicle-mounted terminal here can be a terminal device that can be used for modern management of transport vehicles, including: driving safety monitoring management, operation management, service quality management, intelligent centralized dispatching management, electronic stop sign control management, etc. Terminal ...

The invention relates to a vehicle fault code reading method and device, and a vehicle fault statistics system; the method comprises the following steps: reading fault state mark signals of all electronic controllers of the vehicle in real time, wherein the fault state mark signals refer to the signals self-defined in the vehicle electronic controllers and are used for marking whether faults exist in the vehicle or not; sending a vehicle fault code reading request order to the electronic controller if the fault state mark signal of a random electronic controller is switched to the fault state, wherein the mark signal at least marks a fault state or a non-fault state; obtaining vehicle fault codes returned by all electronic controllers, and uploading the vehicle fault codes to a backstage server, wherein the electronic controllers receive the vehicle fault code reading request order and return the internal monitored fault codes. The method can reduce the intelligent vehicle terminal resource occupations, thus preventing random faults from being missed, and reducing influences on the vehicle network by fault checking.
Description
technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a vehicle fault code reading method and device, and a vehicle fault statistics system. Background technique [0002] With the promotion of Internet of Vehicles and big data, the vehicle fault statistics function has become a basic function of big data statistical analysis. The conventional implementation method is that the vehicle terminal periodically sends diagnostic commands to read the fault codes and related environmental parameters of each node. If there are fault codes, the fault information and related environmental parameters are uploaded to the background server, and the background server counts the faults. [0003] In the above technical solution, the intelligent vehicle-mounted terminal needs to periodically read the fault codes, which occupies the sending and receiving resources of the intelligent vehicle-mounted terminal. Due to the periodic query, it i...
