Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

It is relatively common for vehicles to break down. Some failures can be checked or handled by the driver himself. However, due to experience and other reasons, the driver does not know enough about the functions and performance of the vehicle, so he needs to check the relevant documents to grasp it. When the vehicle is equipped with the fault prompt system in this manual, the driver can know the current fault attributes through the fault prompt system of the vehicle, provide the basis for the driver to make correct handling methods, and eliminate the driver's doubts.

When the vehicle breaks down, the fault prompt system will broadcast the current fault; when the fault severity level is not high (does not affect normal driving), the fault prompt system will confirm with the customer whether it is necessary to call out the relevant information of the fault; if the fault severity level is high ( affect safe driving), the fault prompt system immediately informs the user to stop, and compulsively plays the fault detailed video data to guide the user to confirm the fault.

A feasible embodiment of this specification provides a vehicle failure prompt system, as shown in Figure 1-7, the system includes:

In this embodiment, files related to vehicle faults are stored in the fault database 100 in the form of audio and/or video files, and the driver is prompted by playing these files. When a fault occurs, the system judges and classifies the fault, and prompts according to the classification result. If the fault does not affect driving safety, it is up to the driver to decide whether to play the audio or video file related to the fault problem; if the fault will affect driving safety, the system will forcibly play the audio or video file related to the fault problem. When no breakdown occurred, the driver could also call out the relevant information on the breakdown by the voice system or button 502 for learning.

It should be noted that the failure classification criteria described in this manual can also adopt other methods, such as dividing the failure into multiple levels first, and then judging the relationship between the failure level and the critical value M level. Class M is the critical level for judging whether a fault problem will affect driving safety. When the fault level is greater than M level, the fault problem is judged as a fault problem that will affect driving safety; when the fault level is not greater than M level, the fault problem is judged as a fault problem that will not affect driving safety.
