In order to facilitate understanding of the above-described technical aspects of the present invention, the above-described technical aspects of the present invention will be described in detail below in terms of specific usage.
The equipment for carrying out fault prompt by utilizing the vehicle-mounted sound comprises an electronic controller ECU, a CAN bus and the vehicle-mounted sound (or a sound system), wherein the vehicle-mounted sound comprises a sound controller, a loudspeaker and a touch display screen. The touch display screen is used for realizing human-computer interaction. The sound controller displays the fault confirmation key through the touch display screen, and the driver finishes broadcasting the fault prompt by touching the fault confirmation key.
Because the automobile is provided with the sound system, the system can be fully utilized for fault indication. The invention utilizes the existing sound system of the automobile, can broadcast the fault content through the sound system when the fault occurs, and indicates the driver to take certain measures without additionally arranging other hardware.
The electronic controller ECU can also be called a whole vehicle system unit, an electronic control unit and the like. If the automobile is a fuel automobile, the ECU can be an engine controller EMS, and if the automobile is an electric automobile, the ECU can be a battery management system BMS or a vehicle control unit VCU.
During concrete implementation, firstly, the sound system and the ECU (electronic control unit) of the electronic controller are required to be connected to the same CAN bus, and secondly, the internal logic of the sound system is required to be modified, so that the sound system CAN identify fault messages on the CAN bus according to CAN network definition, and the sound system CAN broadcast preset fault contents and processing measures according to different fault information.
The working principle is that the electronic controller ECU CAN send a fault message on a CAN (controller area network) bus after detecting a fault, and the sound system determines fault information and broadcasts fault content and processing measures after receiving the fault message from the CAN bus.
When the automobile fault alarm is used specifically, after an automobile has a fault, the original fault response (namely fault prompt) is not influenced and is normally triggered; in addition, the electronic controller ECU sends the fault message to the sound controller, and the sound controller sends out the fault prompt audio (including fault content and processing measures) recorded in advance. After the fault occurs and the fault prompting audio is broadcasted at least once, the driver can shut down the broadcasting of the fault prompting audio in a mode of manually touching a fault confirming key, and the fact that the driver knows the fault is proved; if the fault exists all the time, the fault prompting audio frequency is broadcasted once when the vehicle is started every time.
In conclusion, by means of the technical scheme of the invention, the existing vehicle-mounted sound equipment of the automobile can be utilized, when a fault occurs, the fault content is broadcasted through the vehicle-mounted sound equipment, and the driver is instructed to take certain measures, so that the driver can be given a clearer and more obvious fault prompt, and the use safety of the automobile is improved.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
