[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

[0030] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] As described in the background art, the existing vehicle light control technology still needs to be improved in terms of detection accuracy and response speed. For example, when detecting that the vehicle owner is leaving or approaching the vehicle, it is not possible to accurately control the switching of the vehicle lights.

[0036] In order to solve the above problems, Figure 1 As shown, the present application provides a vehicle lamp system, including a lampshade and a light source 10 arranged in the lampshade; a distance detection module 20, arranged in the lampshade; a vehicle lamp controller 30, connected to the distance detection module 20 and the light source 10, and the vehicle lamp controller 30 is used to control the light source 10 according to the detection result of the distance detection module 20.

[0037] The vehicle lighting system may be, for example, a vehicle headlight module. The lampshade of the vehicle headlight module generally has sufficient space, which can be used to install the distance detection module 20, which not only facilitates the distance detection module 20 to measure the distance of objects outside the vehicle and improves the detection accuracy, but also eliminates the need to design an additional installation position for the distance detection module 20, which can reduce costs and help improve the aesthetics of the vehicle shape.

[0038] In some embodiments, the distance detection module 20 can be installed in each of the four headlight covers of the car, so that distance measurement can be achieved from the front, back, left, and right directions of the car, providing a sufficient data source for the intelligent control of the headlights.

[0039] As an optional implementation, the distance detection module 20 includes an ultra-wideband detection module (UWB, UltraWide Band).

[0040] The detection module is a device that uses ultra-wideband technology to perform high-precision position detection, and has the advantages of high transmission rate, strong anti-interference ability, and high positioning accuracy. This technology uses a very wide frequency band and can achieve high-precision position information detection at the centimeter level. It uses the time of sending and receiving signals to detect the position, so it has high security. As an example, the operating frequency of the ultra-wideband distance detection module 20 is 3.1GHz-10.6GHz, and the transmission power can be -41.3dB / MHz.

[0041] By installing an ultra-wideband detection module into the lampshade for distance detection and sending the detection data to the headlight controller 30, the headlight controller 30 controls the light source 10 according to the detection results, which can greatly improve the detection accuracy and provide accurate data support for the intelligent control of the headlights.

[0042] As an optional implementation, Figure 2 As shown, the vehicle light controller 30 has a data parsing module 31 ; the vehicle light controller 30 can receive and parse the detection data from the distance detection module 20 to obtain the detection result.

[0043] The above-mentioned vehicle lamp system can process the detection data measured by the distance detection module 20 by using the data analysis module 31 of the vehicle lamp controller 30, and there is no need to configure a resolution chip specifically for the distance detection module 20, which can reduce costs. Furthermore, by embedding the distance detection module 20 into the vehicle lamp cover, the sealing property of the lamp cover can be used to protect the distance detection module 20, thereby saving the cost of the waterproof protective cover.

[0044] Optionally, the distance detection module 20 may be embedded into the circuit board at the lamp end to further reduce the wiring harness, reduce the complexity of wiring and electromagnetic interference, and improve the stability and reliability of the system.

[0045] As an optional implementation manner, the detection data includes: the distance between the object or person outside the vehicle and the distance detection module 20.

[0046] For example, the vehicle light controller 30 may obtain the distance between the object or person outside the vehicle and the distance detection module 20 from the distance detection module 20 , and control the light source 10 to make corresponding adjustments according to the change of the distance information.

[0047] As an optional implementation, the light source 10 includes a welcoming lighting effect mode and a seeing-off lighting effect mode, and the vehicle light controller 30 can control the light source 10 to select a corresponding lighting effect mode according to the detection result of the distance detection module 20 .

[0048] For example, when the car owner approaches the car, the distance detection module 20 can detect that the distance between the car owner and the car is constantly decreasing, and transmit the detection data to the headlight controller 30. The headlight controller 30 can determine that the car owner is approaching the vehicle based on the changes in the detection data, thereby controlling the light source 10 to adjust to the welcome lighting effect mode.

[0049] When the owner moves away from the car, the distance detection module 20 can detect that the distance between the owner and the car is increasing, and transmit the detection data to the headlight controller 30. The headlight controller 30 determines that the owner is moving away from the vehicle based on the changes in the detection data, and thus controls the light source 10 to adjust to the guest-seeing lighting effect mode.

[0050] As an optional implementation method, the welcoming lighting effect mode includes: controlling the brightness of the light source 10 to gradually increase until it reaches a preset brightness; the seeing-off lighting effect mode includes: controlling the brightness of the car lights to gradually decrease until they are completely extinguished.

[0051] For example, when the owner approaches the vehicle, the light controller 30 can control the light source 10 to adjust to the welcoming light effect mode according to the detection result of the distance detection module 20, that is, control the brightness of the light source 10 to gradually increase until it reaches the preset brightness. When the owner moves away from the vehicle, the light controller 30 can control the light source 10 to adjust to the seeing-off light effect mode according to the detection result of the distance detection module 20, that is, control the brightness of the light source 10 to gradually decrease until it is completely extinguished.

[0052] By providing different lighting effect modes and combining the detection data obtained by the distance detection module 20, intelligent control of the car lights can be achieved to improve the user experience. In addition, by installing an ultra-wideband detection module in the lampshade, the distance detection accuracy can be greatly improved, making the switching and brightness adjustment of the car lights more accurate and avoiding energy waste.

[0053] Optional, such as Figure 3 As shown, the lampshades of the front and rear lights are both equipped with distance detection modules 20. When the light controller 30 receives detection data from the distance detection module 20 of the front light, the front light source 11 can be controlled to be a welcoming light effect mode or a seeing-off light effect mode; when the light controller 30 receives detection data from the distance detection module 20 of the rear light, the rear light source 12 can be controlled to be a welcoming light effect mode or a seeing-off light effect mode.

[0054] As an optional implementation, Figure 4As shown, the distance detection module 20 is also communicatively connected to the vehicle-mounted biological detection module 40; the vehicle-mounted biological detection module 40 can detect whether there is a biological signal in the vehicle, and send the detection result to the distance detection module 20; the headlight controller 30 can receive the detection result from the distance detection module 20, and control the light source 10 to send a warning signal.

[0055] For a vehicle equipped with an on-board biological detection module 40, the communication function of the distance detection module 20 can be used to establish a communication connection with the on-board biological detection module 40 to receive the detection results of the on-board biological detection module 40 and forward the detection results to the headlight controller 30. The headlight controller 30 determines whether it is necessary to control the light source 10 to send a warning signal based on the detection results.

[0056] For example, when the owner forgets a child or pet in the car after getting out of the car, the onboard biological detection module 40 can detect biological signals in the car, thereby determining that there are people or pets in the car. The onboard biological detection module 40 can transmit the detection result to the headlight controller 30 through the ranging detection module, and the headlight controller 30 controls the light source 10 to send a warning signal, for example, controlling the headlights to flash continuously, or controlling the light emission duration of the light source 10 to send an SOS signal.

[0057] The present application also discloses a control method for a vehicle light system, which can be used to control the vehicle light system in any of the above embodiments, including:

[0058] S101: Detecting the distance between an object or person outside the vehicle and the distance detection module 20;

[0059] S103: Determine the change trend of the distance. If the distance gradually decreases, control the light source 10 to turn on and gradually increase the brightness to a preset brightness; if the distance gradually increases, control the brightness of the light source 10 to gradually decrease until it is completely extinguished.

[0060] For example, an ultra-wideband detection module installed in the lampshade can be used to detect the distance between an object or person outside the vehicle and the vehicle. The headlight controller 30 can determine whether the owner is approaching or moving away from the vehicle based on the trend of the distance change, and then control the light source 10 of the headlight to emit different lighting effects. For example, when the distance gradually decreases, the headlight controller 30 can determine that the owner is approaching the vehicle, and control the light source 10 to turn on, and the brightness gradually increases to a preset brightness; when the distance gradually increases, the headlight controller 30 can determine that the owner is moving away from the vehicle, and control the brightness of the light source 10 to gradually decrease until it is completely extinguished.

[0061] As an optional implementation, the control method of the vehicle light system further includes:

[0062] S105: receiving a detection signal from the vehicle-mounted biological detection module 40;

[0063] S107: Determine whether there is someone in the car according to the detection signal; if yes, control the light source 10 to send out a warning signal.

[0064] The vehicle light system can also cooperate with the vehicle-mounted biological detection module 40 to control the light source 10 to send out a warning signal when a child or pet is left in the vehicle. Specifically, when the vehicle-mounted biological detection module 40 detects biological signals in the vehicle, the detection signal can be first sent to the distance detection module 20 installed in the lampshade, and then sent to the vehicle light controller 30 by the distance detection module 20. When the vehicle light controller 30 receives the detection signal, it determines that there is someone in the vehicle. At this time, the vehicle light controller 30 controls the light source 10 of the vehicle light to send out a warning signal, such as controlling the vehicle light to flash continuously.
