Description

Technical Field

[0001] This utility model relates to the field of automotive lighting systems, specifically to a parking lighting system based on parking assistance and headlight activation signals. Background Technology

[0002] When parking in low-light conditions, drivers often struggle to see the sides of their vehicles clearly, whether using rearview mirrors or surround-view cameras. This can easily lead to accidents such as tires running over or scraping against curbs, or scraping against other vehicles.

[0003] The main problems with traditional methods are:

[0004] 1. The vehicle only has front lighting and reversing lights, but no side lighting.

[0005] 2. When parking in low ambient light conditions, it is impossible to clearly see the actual road surface and road shoulder when observing the sides of the vehicle through the rearview mirror.

[0006] 3. When parking in low ambient light conditions, it is impossible to clearly see the actual road surface and shoulder conditions when observing the sides of the vehicle through the surround-view camera.

[0007] 4. When the actual road surface and shoulder conditions are not clearly visible, blindly reversing can easily cause accidents such as the tires running over the shoulder, scraping against the shoulder, or scraping against surrounding vehicles.

[0008] 5. When parking in older residential areas with limited parking spaces at night, it is common to encounter situations where the surrounding area is complex and the ambient light is low. To ensure safety, it is necessary to get out of the car repeatedly to observe the surroundings, resulting in lower driving comfort and safety.

[0009] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0019] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0020] Example 1

[0021] Figure 1 This is a schematic diagram of the structure of this utility model.

[0022] like Figure 1 As shown, a parking lighting system based on parking assist and headlight activation signals includes: an electronic controller ECU 100, a first parking light 200, and a second parking light 300. The electronic controller ECU 100 is connected to the first parking light 200 and the second parking light 300. The first parking light 200 and the second parking light 300 are respectively installed below the left and right rearview mirrors of the vehicle. The electronic controller ECU 100 is installed next to the vehicle's fuse box.

[0023] The electronic controller ECU 100 includes: a microcontroller MCU 110, a first resistor R1120, a second resistor R2130, a third resistor R3140, a fourth resistor R4150, a first MOSFET Q1160, a first diode D1170, a second diode D2180, a fuse F1190, a first socket J11100, a second socket J21110, a third socket J31120, a fourth socket J41130, a fifth socket J51140, and a sixth socket J61150. The sixth socket J61150 is connected to one end of the fuse F1190, and the other end of the fuse F1190 is connected to the anode of the first diode D1170. The cathode of the first diode D1170 is connected to the microcontroller MCU. The positive terminal of MCU 110 is connected to the fifth socket J51140. The drain of the first MOSFET Q1160 is connected to the fourth socket J41130. The gate of the first MOSFET Q1160 is connected to one end of the first resistor R1120, the second resistor R2130, and the third resistor R3140. The other end of the first resistor R1120 is connected to the cathode of the second diode D2180 and the output control terminal of the microcontroller MCU 110. The other end of the second resistor R2130 is connected to the anode of the second diode D2180. The other end of the third resistor R3140, the negative terminal of the microcontroller MCU 110, and the source of the first MOSFET Q1160 are connected to the third socket J31120. The two fixed terminals and one movable terminal of the fourth resistor R4150 are connected to the microcontroller MCU 110. The setting input terminal of 110 is connected; the fourth socket J41130 is connected to the negative terminal of the first parking light 200 and the second parking light 300; the fifth socket J51140 is connected to the positive terminal of the first parking light 200 and the second parking light 300; the first socket J11100 is connected to the vehicle's parking assist activation signal; the second socket J21110 is connected to the vehicle's headlight activation signal; the third socket J31120 is connected to the negative terminal of the vehicle's 12V power supply; and the sixth socket J61150 is connected to the positive terminal of the vehicle's 12V power supply.

[0024] In this invention, the positive terminal of the vehicle's 12V power supply powers the entire circuit via the sixth socket J61150, fuse F1190, and first diode D1170. The negative terminal of the vehicle power supply provides a negative circuit to the electronic control unit (ECU) 100 via the third socket J31120. Fuse F1190 provides overcurrent protection for the entire circuit, and the first diode D1170 prevents reverse connection, ensuring circuit safety. The positive terminals of the first parking light 200 and the second parking light 300 are connected to the positive terminal of the 12V power supply via the fifth socket J51140. The microcontroller (MCU) 110 determines whether parking lights need to be activated based on the parking assist and headlight activation signals input from the first socket J11100 and the second socket J21110. When parking assist and headlights are activated simultaneously, the MCU 110 determines that the vehicle is currently parking in an environment of insufficient lighting.

[0025] Once the microcontroller MCU 110 determines that the vehicle is parking in an environment with insufficient lighting, it controls the first MOSFET Q1160 to operate, thereby connecting the fourth socket J41130 and the third socket J31120. This allows the first parking light 200 and the second parking light 300 to receive negative power and illuminate. When the parking assist or headlight signal disappears, the microcontroller MCU 110 controls the first MOSFET Q1160 to turn off, thereby disconnecting the negative power supply to the first parking light 200 and the second parking light 300, turning off the parking lights.

[0026] The first resistor R1120 and the third resistor R3140 provide a suitable gate voltage for the first MOSFET Q1160 to turn on. The second diode D2180 and the second resistor R2130 are used to speed up the turn-off speed of the first MOSFET Q1160. The microcontroller MCU 110 adjusts the brightness of the parking lights by controlling the duty cycle of the first MOSFET Q1160.

[0027] The driver adjusts the fourth resistor R4150 to set the parking light brightness according to their personal usage habits. The microcontroller MCU110 automatically adjusts the parking light brightness to the driver's desired brightness based on the set value of the fourth resistor R4150, and ensures that the parking light brightness does not change with the vehicle's generator voltage.

[0028] In summary, this system utilizes activation signals from both the parking assist and headlight systems to determine if the vehicle is parking in low-light conditions. If low-light conditions are detected, the system immediately activates the parking lights, allowing the driver to clearly see the sides of the vehicle and complete a safe and comfortable parking maneuver. Once the parking assist or headlight activation signal disappears, the system automatically deactivates the parking lights. Drivers can set the parking light brightness according to their personal preferences, and the system automatically adjusts the brightness based on the driver's settings and the vehicle's voltage. This ensures that when parking in low-light conditions, the system automatically activates the parking lights, allowing the driver to easily see the sides of the vehicle using both the rearview mirror and the surround-view camera, thus improving parking comfort and safety.

[0029] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
