Description

High beam control system and automobile data recorder with same

Technical Field

The utility model relates to a car light intelligence switch technique, especially high beam intelligent switch.

Background

Improper operation of high beam lamps during night driving is one of the main causes of automobile accidents, and it is counted that such accidents can account for 35% of the total accidents of automobiles. For the existing automobile, the intelligent control of the front lamp is widely applied, and the main principle is to detect the ambient light around the automobile by using a photosensitive element and automatically turn on or off the automobile front lamp according to the intensity of the ambient light. However, the high beam cannot be automatically controlled by the photosensitive element, when automobiles interact at night, both parties meeting the automobiles should turn off the high beam, but after the high beam is turned on by the automobile, the ambient light 10 meters in front of the automobile can reach 0.9Lux, the light intensity of the environment 10 meters to 100 meters ahead is covered, and whether the automobile lamp is turned on by the oncoming automobile cannot be known by the photosensitive element. Therefore, an optical imaging AI system or a laser radar and millimeter wave radar ranging system is adopted for individual high-end vehicle models to judge whether vehicles on the opposite side exist in the front or not, so that high beam control is performed, but the two systems are large in size, high in energy consumption, too complex in hardware, too high in cost, poor in control effect and incapable of being applied and popularized on a large scale.

At present, the automobile data recorder is already a standard assembly of most automobiles, the automobile data recorder is fixedly installed at the upper end of a front windshield of the automobile, the position is a better detection position for a contralateral light source, and the automobile needs a high beam control system which is low in cost, small in size and capable of being integrated with the automobile data recorder urgently.

The phototriode of the hollow tube shields light close to the phototriode due to the fact that the photosensitive surface of the phototriode is protruded by the tube, and therefore the light of the high beam emitted by the vehicle is greatly weakened when the phototriode is detected, the phototriode is only sensitive to light traveling in the opposite direction, and whether the high beam is turned on in the opposite direction or not can be well judged at the moment. The working process of the high beam control system is as follows: after the original automobile high beam switch of the automobile is switched off, the device starts to work, when the probe assembly detects that light is dark, namely, no automobile headlamp in the front of the automobile is lighted and no oncoming automobile is available, the controller judges that the high beam switch of the automobile combination lamp switch is closed by the connector, and the automobile high beam is switched on. When a vehicle with the headlights is driving head on, the light signal measured by the probe assembly is transmitted to the controller, and then the high beam is turned off according to an instruction.

This application high beam lamp control system control car high beam's connected mode does not influence the driver and passes through former car headlight control switch control high beam, equal to and parallelly connected a new return circuit in former car combination lamp switch, the switching of new return circuit control high beam only, do not have the relation with other headlamps, and former car manual control means and this application high beam lamp control system do not conflict, whether open high beam lamp control system after installing high beam lamp control system additional and do not influence driver's manual control high beam, also can carry out the dismouting fast when need not this device.

The high beam control system volume in this application is less, can directly be integrated with current vehicle event data recorder to control and power supply by vehicle event data recorder. Generally speaking, the probe assembly is aligned with the direction of the automobile driving direction and the direction of the automobile data recorder camera, if the automobile data recorder camera has a light source tracking function, the probe assembly can also work together with the automobile data recorder camera, and the capability of capturing the light source of the opposite driving vehicle and screening the ambient light nearby the automobile is improved.

Compared with the prior art, far-reaching headlamp control system can be according to the switching of ambient light and relative vehicle state automatic control far-reaching headlamp in this application to this far-reaching headlamp control system is with low costs, small, can integrate to work jointly with far-reaching headlamp control system camera in the vehicle event data recorder.
