Description

Technical Field

[0001] This invention relates to the field of active safety control technology for motor vehicles, specifically to an intelligent adaptive lighting control device for motor vehicles that can be adapted to multiple vehicle models, multiple sensing sources, and multiple assembly forms. Background Technology

[0002] Currently, the switching between high and low beams of motor vehicle headlights largely relies on manual operation by the driver. Improper use of high beams at night can easily cause glare to oncoming vehicles, posing a serious traffic safety hazard. Existing adaptive high / low beam control solutions are mostly factory-installed solutions, only compatible with specific vehicle models and unable to cover commercial vehicles, motorcycles, tricycles, etc. Aftermarket lighting control devices generally suffer from complex modifications, requiring damage to the original vehicle's electrical or optical circuits, and the inability to reuse sensing equipment. Furthermore, existing technologies are mostly tied to dedicated sensing hardware and fixed communication interfaces, making them easily circumvented. They also lack adaptive adaptability to different national / regional traffic regulations, and some solutions lack interfaces for data retention and law enforcement evidence collection, making it difficult to meet the needs of compliant use and cross-regional promotion. Their universality, practicality, and patent protection are all significantly insufficient. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an intelligent adaptive lighting control device for motor vehicles, which is compatible with passenger cars, commercial vehicles, motorcycles, and tricycles. It supports multiple road condition sensing signal sources, does not limit communication interfaces or assembly forms, and supports modular satellite positioning and regional regulatory adaptation. It can achieve intelligent adaptive switching between high beam and low beam.

[0004] The device of the present invention includes: a main control module, a road condition signal acquisition unit, and a vehicle status acquisition unit; The road condition signal acquisition unit is used to collect illumination and visual perception signals of the external road condition environment of the motor vehicle; The vehicle status acquisition unit is used to acquire motor vehicle driving status data; The main control module controls the vehicle's headlights to adaptively switch between high beam and low beam based on the road condition perception signal and driving status data.

[0005] The sources of the sensing signals collected by the road condition signal acquisition unit include any one or more of the following: vehicle dashcam, original factory vehicle camera, millimeter-wave radar, mobile terminal camera, and external visual sensing device.

[0006] When the signal source is a dashcam, the road condition signal acquisition unit adopts a passive optical beam splitting structure, reuses the dashcam's optical path to acquire road condition signals, and does not interfere with the dashcam's original imaging and recording functions.

[0007] When the signal source is a mobile terminal camera, the road condition signal acquisition unit acquires the road condition visual signal collected by the mobile terminal through a wired interface or wireless communication.

[0008] The device can be an independent external structure or integrated into the vehicle's infotainment system, original vehicle computer, or electronic control unit, directly calling the original vehicle's perception data and vehicle data to achieve lighting control; the independent external device does not require modification of the original vehicle's circuitry, optical path, or interior, and can be directly installed and used.

[0009] The device is equipped with a standardized data interaction interface for exporting, storing, and using the device's operation control data for law enforcement evidence collection.

[0010] The main control module is equipped with a pluggable expansion interface, which can selectively connect to a satellite positioning module. The satellite positioning module integrates a positioning unit and a configurable traffic regulation storage unit. The storage chip capacity can be flexibly selected according to the area of ​​use, and it supports two traffic regulation data writing modes: factory pre-programming and external online programming.

[0011] When connected to a satellite positioning module, the main control module optimizes the lighting control strategy by combining real-time geographical location and corresponding regional regulations; when not connected to a satellite positioning module, the device can still independently complete the core adaptive switching function between high beam and low beam.

[0012] The vehicle status acquisition unit acquires driving status data in any of the following ways: OBD interface, CAN bus, original vehicle expansion interface, wired communication, and wireless communication, without being limited by a specific interface form.

[0013] The device of this invention can be widely adapted to passenger cars, commercial vehicles, motorcycles and tricycles. It has flexible sensing sources, high interface compatibility and diverse assembly forms. It can be used for non-destructive retrofitting as well as pre-installation integration by car manufacturers. At the same time, it meets the regulatory adaptation and law enforcement compliance requirements of different regions around the world. Attached Figure Description

[0017] Example 1: Rear-mounted external solution (suitable for passenger cars / commercial vehicles) like Figure 1 , Figure 2 As shown, the device adopts an independent external structure. The road condition signal acquisition unit is a passive optical beam splitter unit, which is installed at the front of the dashcam lens to split the dashcam's optical path into two paths. One path is used for normal recording by the dashcam, and the other path transmits the road condition light signal to the main control module.

[0018] The vehicle status acquisition unit obtains driving data such as vehicle speed and light status through the OBD interface, and the main control module controls the headlights to switch adaptively based on road condition signals and driving data.

[0019] The device is equipped with a standardized data interface, which can export operational data for law enforcement evidence collection. It can be installed without modifying the original vehicle circuitry and interior, achieving non-destructive installation.

[0020] Example 2: Motorcycle / Tricycle Mobile Terminal Adaptation Solution like Figure 4 As shown, the road condition signal acquisition unit connects to the mobile phone camera via USB or Bluetooth to acquire road condition visual signals, the vehicle status acquisition unit acquires the vehicle driving status via wireless communication, and the main control module executes the light switching control. No dedicated sensing hardware is required, making it suitable for simple vehicle models.

[0021] Example 3: Pre-installed integration solution (vehicle manufacturer / vehicle infotainment system integration) The device is integrated into the vehicle's infotainment system or the original vehicle ECU. The road condition signal acquisition unit directly calls the data from the original vehicle camera or millimeter-wave radar, and the vehicle status acquisition unit obtains driving data through the CAN bus. The function can be deployed through online upgrades at 4S stores, adapting to the pre-installation mass production needs of car manufacturers.

[0022] Example 4: Enhanced Regional Regulatory Adaptation Scheme like Figure 3 As shown, the main control module is plugged into the satellite positioning module. The module has a built-in traffic regulation storage chip. The storage capacity is selected according to the target area and the corresponding regulations are burned in.
