The utility model discloses utilize remote control key, door control unit and automobile body the control unit to realize that alone operation just can inspect the light that relates to vehicle safety. Thereby avoiding the vehicle traffic accident caused by unclear sight due to the problem of vehicle light.
Description
Technical Field
The utility model belongs to heavy truck light control field, concretely relates to heavy truck light self-checking system.
Background
The lighting system plays a very important role in the daily driving process of people, more than half of traffic accidents occur at night, and the reasons of the traffic accidents occur at night are known, so that most of the traffic accidents are caused by unclear sight of drivers. Therefore, the automobile lighting system plays a great active role in driving safety. Especially for heavy trucks, the hazard and damage is more severe if a traffic accident occurs. Although the vehicle lighting system is important, if a driver cannot perform relevant inspection on the vehicle lighting system at all, functions such as a brake lamp and a backup lamp need to be operated by one person for inspection. Therefore, if a driver drives the vehicle, the driver cannot know whether the conditions of the brake lamp and the backup lamp are good or not and whether the fault exists or not. The vehicle is run under the unknowing condition, so that the hidden danger of the vehicle lighting system is caused, and the running risk is increased.
SUMMERY OF THE UTILITY MODEL
The utility model provides a heavy truck light self-checking system needs cooperation personnel's problem when solving original light inspection, realizes that a driver just can carry out the purpose of whole inspections to the light of vehicle.
In order to solve the technical problem, the utility model provides a heavy truck light self-checking system, its characterized in that: comprises a door control unit, a vehicle body control unit and a remote control key; the remote control key is provided with a light self-checking button for sending a self-checking signal to the door control unit, the door control unit sends a light self-checking message to the vehicle body control unit through a vehicle bus after receiving the remote self-checking signal of the remote control key, pins of the vehicle body control unit are respectively connected with detected lamps on the vehicle through cables, and the detected lamps are controlled to be sequentially lightened.
Has the advantages that: the utility model discloses utilize remote control key, door control unit and automobile body the control unit to realize that alone operation just can inspect the light that relates to vehicle safety. Thereby avoiding the vehicle traffic accident caused by unclear sight due to the problem of vehicle light.

Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following description will be made in further detail with respect to the embodiments of the present invention.
The utility model provides a light self-checking system of heavy truck, which comprises a door control unit, a truck body control unit and a remote control key;
the remote control key is provided with a light self-checking button, a driver presses the light self-checking button in the front and the rear of the vehicle, the door control unit receives a remote signal of the remote control key and then sends a light self-checking message to the vehicle body control unit through a vehicle bus, pins of the vehicle body control unit are respectively connected with the wide indicator lamp, the dipped headlight, the high beam lamp, the steering lamp, the fog lamp, the brake lamp and the reversing lamp through cables, the wide indicator lamp, the dipped headlight, the high beam lamp, the steering lamp, the fog lamp, the brake lamp and the reversing lamp are sequentially lightened, and therefore the effect that one driver can carry out all checks on the light of the vehicle is achieved.
The door control unit and the vehicle body control unit are connected with a system voltage (24V), when the door control unit is in a sleep state, the remote control key sends a remote light self-checking signal to the door control unit, after the door control unit receives the remote control signal, the vehicle body controller is awakened through a high level signal of a pin A17 of the door control unit, a light self-checking message is sent to the vehicle body control unit through a vehicle bus, when the vehicle body control unit is in the sleep state, the vehicle body control unit enters an awakening state after detecting that the door control unit awakens the high level signal, when the remote control key state message is received, the light self-checking is carried out, a vehicle indicator light, a dipped headlight, a high beam, a steering lamp, a fog lamp, a brake lamp and a reversing lamp are sequentially lightened, a small lamp, the dipped headlight, the high beam, the steering lamp and the fog, the next self-checking signal can be responded after the self-checking of the whole period is finished, and meanwhile, fault processing is carried out.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
