[0003] See attached Figure 2 As shown, when most cars are unlocked, the turn signal lights will flash several times, and the control panel will detect the turn signal through the turn detection line and turn on the welcome light to realize the welcome function;

[0004] The existing welcome lamp has the following shortcomings:

[0005] 1. Single function, can only be turned on by the turn signal line, can not be turned on when the door is opened or reverse

[0006] 2. The switching time is fixed and cannot be adjusted flexibly;

[0007] 3. It cannot be turned off during the day (since it is installed outside the car, the effect is not obvious when the welcome light is turned on during the day)

[0008] 4. When driving, the welcome lights will be triggered and lit up due to turning. Utility Model Content

[0009] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a novel rear-mounted vehicle welcome light that can overcome the above problems or at least partially solve the above problems.

[0010] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a new type of rear-mounted vehicle welcome light, including: a main control module, connected to the car, used to obtain the working status of the car in real time; a left sub-control module and a right sub-control module, which control the opening or closing of the welcome light; a remote control module, which is used to remotely control the main control module; a processor module, which is used to process and analyze the working status of the car obtained by the main control module.

[0011] Preferably, the main control module includes MCU1, Bluetooth or wireless transmission (RF), and a car CAN-BUS protocol interface. The main control module is installed on the center console of the car. The main control module is connected to the CAN-BUS of the car through a CAN-BUS protocol line. The main control module is connected to the auxiliary control module through Bluetooth or wireless transmission (RF).

[0012] Preferably, the left sub-control module and the right sub-control module include MCU2 / MCU3, Bluetooth or wireless transmission (RF). The left sub-control module and the right sub-control module are connected to the main control module via Bluetooth or wireless transmission (RF) to receive the processor module signal to drive the welcome light to turn on or off.

[0013] Preferably, the process of the processor module controlling the left auxiliary control module and the right auxiliary control module includes:

[0014] S1, the remote control module sends the control signal to the main control module;

[0015] S2, the main control module obtains the working status of the car in real time from MCU1, and determines whether the welcome light needs to be turned on in the current state according to its own set working logic;

[0016] S3, the processor module analyzes the collected working status signal;

[0017] S4. The processor module sends the analysis results to the left sub-control module and the right sub-control module.

[0018] Furthermore, in S2, the process of the processor module analyzing the collected working status signal includes:

[0019] R=A1*(B1*C1+B2*C2+B3*C3+B4*C4+V),

[0020] Among them, A1 is the control signal value of the remote control end,

[0021] When the remote control terminal controls the welcome light to turn on, A1=1;

[0022] When the remote control terminal controls the welcome light to turn off, A1=0;

[0023] When the remote control terminal controls the welcome light automatically, A1=0.5;

[0024] B1 is the brightness signal value of the light outside the car.

[0025] When the light outside the car is bright, B1 = 0;

[0026] When the light outside the car is dark, B1=1;

[0027] B2 is the car locking signal value,

[0028] When the car is locked, B2 = 0;

[0037] V is the correction parameter for controlling the welcome light; (specifically obtainable from empirical data);

[0038] Compare R with the preset reference value W;

[0039] If R ≥ W, the processor generates a signal to turn on the welcome light;

[0040] If R < W, the processor generates a signal to turn off the welcome light.

[0041] After adopting the above technical solution, the present utility model has the following beneficial effects compared with the prior art: The present utility model obtains the vehicle working state through the main control module, including the brightness of the external light of the vehicle, the vehicle unlocking state, the door opening state, the turning state, the reverse state, etc. Furthermore, in different states, the main control module can drive whether the welcome light is turned on through the left sub-control module and the right sub-control module; Therefore, this device can light up the welcome light in multiple scenarios, and through the remote control module, the time of the welcome light can be flexibly set in each scenario, or it can be turned off separately; And it can turn off the welcome light in scenarios where it is not necessary to light up the welcome light, such as during the day or while driving, effectively saving the vehicle's power and increasing the service life of the welcome light;

[0042] And after the vehicle shuts off and locks, the main control module can notify the left sub-control module and the right sub-control module to enter the sleep state, and then the main control module will also enter the sleep state; After entering the sleep state, when the vehicle is unlocked, the vehicle's CAN-BUS will first wake up the main control module, and then the main control module will wake up the left sub-control module and the right sub-control module through Bluetooth or private wireless transmission (RF);

The functions of the main control module of this device are integrated into the main controller of the atmosphere light. Only software adaptation is required. The left and right sub-control modules of this device receive the signals from the main controller of the atmosphere light to control the welcome light, thereby achieving the purpose of cost saving.

[0064] In S2, the process of the processor module analyzing the collected working status signal includes:

[0065] R=A1*(B1*C1+B2*C2+B3*C3+B4*C4+V),

[0066] Among them, A1 is the control signal value of the remote control end,

[0067] When the remote control terminal controls the welcome light to turn on, A1=1;

[0068] When the remote control terminal controls the welcome light to turn off, A1=0;

[0069] When the remote control terminal controls the welcome light automatically, A1=0.5;

[0070] B1 is the brightness signal value of the light outside the car.
