Self-adaptive adjustment control method and system for light sensitivity of automobile driver

Abstract

The invention discloses a self-adaptive adjustment control method and system for the light sensitivity of an automobile driver, and relates to the field of control systems. The method comprises the steps that an adjustment control mode is selected; when the automobile is in a manual control mode, the light brightness of an instrument board is fixed, a headlamp is controlled to be turned on and turned off, and a sunshade curtain is controlled to be opened and closed manually; and when the automobile is in a self-adaptive adjustment control mode, the illuminance of the driver is obtained, and the light brightness of the instrument board, the on-off of the headlamp and the opening and closing of the sunshade curtain are controlled according to the obtained illuminance. According to the invention, the illuminance sensed by a driver can be always in a visual comfortable range, and the driving safety is effectively ensured.

Description

technical field [0001] The invention relates to the field of control systems, in particular to a method and system for self-adaptive adjustment and control of photosensitivity at the driver's place of an automobile. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for intelligent vehicles that are convenient for travel are becoming stronger and stronger. During the driving process, when the driver observes the road conditions ahead and reads the instrument data in the car, the eyes will experience temporary discomfort due to the difference in brightness, or even temporary blindness when the brightness difference is large, which increases driving risks and affects driving safety. . At the same time, when meeting cars at night, if both parties turn on the high beams, there will be a visual blind spot during the meeting, increasing driving risks and affecting driving safety. At present, the driver's photosensiti...

Problems solved by technology

[0003] However, the existing technology only controls the automatic headlights. When the outdoor illuminance changes, while the brightness of the indoor light source instrument panel and the central control screen are fixed, the driver will feel a sudden change in brightness when the driver's line of sight changes, which may easily cause visual discomfort. Temporary blindness occurs when there is a large difference in brightness, which increases driving risks and affects driving safety; the existing technology only controls the start and stop of automatic headlights, and the outdoor illuminance changes in various ways, and headlights with a single brightness value cannot compensate for different outdoor illuminance , weakened, unable to achieve the best driver's sensitivity; the existing technology only sets a threshold value, when the outdoor light intensity fluctuates near the threshold value, the automatic headlights will have the problem of cycle start and stop, resulting in damage to the headlights; the existing The technology compensates the indoor illuminance by controlling the indoor light to achieve constant indoor lighting. However, the car hardly turns on the indoor light during driving, and turning on the indoor light has a great safety hazard to the driving of the vehicle.
