Lamp controller, while head lamp controller obtains the relevant information of vehicle by BCM modules, and the relevant information is passed through into DMD
Pixel type headlamp module projects vehicle front ground.
Further, head lamp controller is made of CAN transceiver, MCU, LED drive chip and DLP control chip；
MCU sends PWM wave to LED drive chip, to adjust the brightness of LED；
Residing different location when MCU is unlocked according to driver obtains the direction of project information, and with the shape of control command
Formula is sent to DLP control chips, to control the projection imaging of DMD pixel type headlamp modules；
Project information is word or pattern.
Further, the information of DMD pixel types headlamp module projection is located at 1.5 meters immediately ahead of headstock；
It is positive that the direction of project information, which is relative to driver,.
Advantageous effect：
1. the present invention can project storage battery electricity, the tire of vehicle when driver unlocks vehicle on vehicle front ground
The relevant informations such as pressure, without starting vehicle.
2. present invention different location residing when can be unlocked according to driver, controls the direction of project information, convenient for driving
Member reads；Further, the information of projection can be word or pattern, and simple, intuitive should be readily appreciated that.
Description of the drawings
Fig. 1 is the car lamp control system Organization Chart of one embodiment of the invention；
Fig. 2 is the car lamp control system working method figure of one embodiment of the invention；
Fig. 3 is the car lamp control system fundamental diagram of one embodiment of the invention；
In figure：1- head lamp controllers, 2-BCM modules, 3-DMD pixel type headlamps module, 4- radio frequency locators.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and examples.
The present embodiment proposes a kind of car lamp control system showing information of vehicles, as shown in Figure 1, it includes headlamp control
Device 1, BCM modules 2, DMD pixel type headlamps module 3 and radio frequency locator 4 processed, DMD pixel type headlamps module 3 and headlamp
Controller 1 is connected by multiple signals line, and head lamp controller 3 is connected with BCM modules 2 by CAN bus, radio frequency locator 4
It is connected by signal with head lamp controller 1；
Radio frequency locator 4 position driver unlock vehicle when the location of, and by the location information be sent to it is described before
Headlight control 1, while head lamp controller 1 obtains relevant information (storage battery information about power, the tire pressure of vehicle by BCM modules 2
Information etc.), and the relevant information is projected into vehicle front ground by DMD pixel type headlamp modules.
As shown in Figure 1, head lamp controller 1 is made of CAN transceiver, MCU, LED drive chip and DLP control chip；
MCU sends PWM wave to LED drive chip, to adjust the brightness of LED；
Residing different location when MCU is unlocked according to driver obtains the direction of project information, and with the shape of control command
Formula is sent to DLP control chips, to control the projection imaging of DMD pixel type headlamp modules；
Project information is word or pattern.
As shown in Fig. 2, vehicle periphery region, which is divided into A, B, C, D, E, first amounts to 5 localization regions, the wherein regions C and D
Processing mode it is identical.That is, the information of projection is towards identical.Particularly, the range of a-quadrant is defined as in headstock position and vehicle
The vehicle left front region that axis is divided；The range of B area is defined as the vehicle that headstock position is divided with vehicle central axes
Right front region；The range in the regions C is defined as the vehicle right back region that headstock position is divided with vehicle central axes；The regions D
Range be defined as the vehicle left back region that headstock position and vehicle central axes are divided；The range in the regions E is defined as distance
Vehicle front region other than 2 meters of headstock.The information that DMD pixel type headlamps module 3 projects is located at apart from immediately ahead of headstock 1.5
At rice.
As shown in figure 3, the location of when by the positioning driver's unlock of radio frequency locator 4, and the location information is sent out
Give head lamp controller 1.Meanwhile head lamp controller 1 obtains the letters such as the storage battery electricity of vehicle, tire pressure by BCM modules 2
Breath, then vehicle front ground is projected by DMD pixel types headlamp 3.Specifically, for example：When driver is located at the unlock of the regions E
When, radio frequency locator 4 navigates to driver and is located at other than 2 meters of vehicle front, and the location information is sent to headlamp control
Device 1.Meanwhile head lamp controller 1 receives the battery voltage information of vehicle, tire pressure etc. by BCM modules 2, and should
