Description

Intelligent control system and control method for car lamp

Technical Field

The invention relates to the field of vehicle control, in particular to an intelligent control system and a control method for a vehicle lamp.

Background

Along with the development of automotive electronics technology, the configuration of on-vehicle electron convenience is more and more, and along with intelligent lighting system's configuration popularization simultaneously, the headlight is not only used for throwing light on in the driving, also can be used for accompanying my returning home when being close to the vehicle, and the vehicle is automatic to carry out the opening of light. The function of 'accompany me to come home' is essentially a headlight delay function. When the light sensor detects that the headlight is in the turn-on state at present, the headlight is turned on and turned off in a delayed mode after a person leaves the vehicle.

Disclosure of Invention

The invention provides an intelligent control system and a control method for a vehicle lamp, which realize the illumination for passengers by controlling the delayed turn-off of a vehicle headlamp.

The utility model provides a car light intelligence control system, BCM passes through the CAN bus and is connected with on-vehicle T-BOX, on-vehicle T-BOX passes through wireless network and is connected with cell-phone APP.

Adopt the distance of cell-phone APP and GPS location's mode to confirm passenger and vehicle, in the distance range of setting for, CAN open the head-light when light sensor detects the current illumination intensity of vehicle, whole car passes through the CAN signal simultaneously and transmits to APP at the background conversion through T-BOX network, and APP suggestion customer carries out the opening of automatic light and the setting of time. If the car owner needs to turn off the car light at the APP end to operate, the light turning-off of the current function of accompanying the car to go home can be carried out. The method realizes that the passenger returns home with oneself at dark night after the vehicle is locked.

An intelligent control method for a vehicle lamp is realized by the following steps:

step one, after receiving a remote controller locking signal, the BCM judges whether the current finished automobile meets a locking condition, and if so, the step two is executed; the locking condition is that all the vehicle doors are closed and the power state is OFF; if not, the process is ended.

Step two, the mobile phone APP is connected with the whole vehicle T-BOX through a wireless network to judge that the distance between the vehicle and the mobile phone APP (vehicle user) is within 150m, if yes, the APP sends an instruction to the T-BOX, the T-BOX awakens the BCM through the CAN network, the BCM dispatches the light sensor through the LIN bus, and step three is executed; if not, the process is ended.

And step three, the light sensor detects whether the current illumination intensity is in the intensity range of the openable light, if so, the light sensor sends a light opening request to the BCM, and after the BCM receives the light opening request of the light sensor, the BCM drives the light to light according to the fact that the distance between the mobile phone APP of the vehicle user and the vehicle sent by the T-BOX is within the set 150 m. If not, the process is ended.

And step four, whether the mobile phone APP actively issues a request for turning off the car lamp or not, if so, the T-box transmits the instruction for receiving the APP to the BCM through the CAN, and the BCM receives the request for interrupting the turning off of the function of returning to home, disconnects the drive of the light and turns off the light. If not, executing the step five;

and step five, finishing when the BCM receives that the distance between the APP sent by the APP and the vehicle is larger than 150m, and if not, returning to the step three.

The invention has the beneficial effects that: the invention realizes the intelligent light control with the function of accompanying me to go home by taking the distance between the position of the vehicle and the owner as a condition through GPS positioning.

According to the invention, the distance between a passenger and a vehicle is known in a mobile phone APP and GPS positioning mode, in a set distance range, when the light sensor detects the current illumination intensity of the vehicle, the headlamp CAN be turned on, meanwhile, the whole vehicle is converted and transmitted to the APP at the background through a CAN signal through a T-box network, and the APP prompts a client to turn on the automatic light and set the time.

Detailed Description

In a first specific embodiment, the present embodiment is described with reference to fig. 1, which is an intelligent control system for a vehicle lamp, including a vehicle Body Controller (BCM), a vehicle-mounted T-BOX, and a mobile phone APP;

the BCM is connected with the vehicle-mounted T-BOX through a CAN bus, and the vehicle-mounted T-BOX is connected with the mobile phone APP through a wireless network.

Adopt the distance of cell-phone APP and GPS location's mode to confirm passenger and vehicle, in the distance range of setting for, CAN open the head-light when light sensor detects the current illumination intensity of vehicle, whole car passes through the CAN signal simultaneously and transmits to APP at the background conversion through T-BOX network, and APP suggestion customer carries out the opening of automatic light and the setting of time. If the car owner needs to turn off the car light at the APP end to operate, the light turning-off of the current function of accompanying the car to go home can be carried out. The method realizes that the passenger returns home with oneself at dark night after the vehicle is locked.

In a second embodiment, the present embodiment is described with reference to fig. 2 and 3, and the present embodiment is a control method of an intelligent vehicle lamp control system described in the first embodiment, and the method is specifically implemented by the following steps:

step one, after receiving a remote controller locking signal, the BCM judges whether the current finished automobile meets a locking condition, and if so, the step two is executed; the locking condition is that all the vehicle doors are closed and the power state is OFF; if not, the process is ended.

Step two, the mobile phone APP is connected with the whole vehicle T-BOX through a wireless network to judge that the distance between the vehicle and the mobile phone APP (vehicle user) is within 150m, if yes, the APP sends an instruction to the T-BOX, the T-BOX awakens the BCM through the CAN network, the BCM dispatches the light sensor through the LIN bus, and step three is executed; if not, the process is ended.

And step three, the light sensor detects whether the current illumination intensity is in the intensity range of the openable light, if so, the light sensor sends a light opening request to the BCM, and after the BCM receives the light opening request of the light sensor, the BCM drives the light to light according to the fact that the distance between the mobile phone APP of the vehicle user and the vehicle sent by the T-BOX is within the set 150 m. If not, the process is ended.

And step four, whether the mobile phone APP actively issues a request for turning off the car lamp or not, if so, the T-box transmits the instruction for receiving the APP to the BCM through the CAN, and the BCM receives the request for interrupting the turning off of the function of returning to home, disconnects the drive of the light and turns off the light. If not, executing the step five;

and step five, finishing when the BCM receives that the distance between the APP sent by the APP and the vehicle is larger than 150m, and if not, returning to the step three.

In this embodiment, when the lighting time exceeds the set time, the light is turned off to finish the process of returning home. The set time for lighting the automobile lamp can be 30s, and can also be set on the mobile phone APP according to actual needs. The distance setting range of the mobile phone APP and the vehicle can also be set according to actual requirements.
