An intelligent control device and method for automobile brake lights and automobile

Abstract

The invention discloses an automobile brake light intelligent control device, a method and an automobile including the control device. Wherein, the intelligent control device of the automobile brake light includes: a light sensor, used to detect the intensity of ambient light, and output a light intensity signal; a brake sensor, used to output a brake signal when it detects that the brake pedal of the automobile is stepped on ; The controller is used to receive the light intensity signal output by the light sensor and the brake signal output by the brake sensor, and control the brake light to emit light when the brake signal is received, and the brightness of the brake light is determined by the controller Determined according to the light intensity signal. The invention judges the different light intensity of the outside when braking, and drives the brake light to display different brightness, which not only plays a better warning role, but also reduces the power consumption of the whole vehicle, and will not cause adverse effects on the driver behind the vehicle. visual stimulation. The invention intelligently controls the different brightness of the brake light, and does not need other operations except stepping on the brake pedal.

Description

technical field [0001] The invention relates to the technical field of automobile lamp control, in particular to an automobile brake lamp intelligent control device and method, and an automobile including the brake lamp intelligent control device. Background technique [0002] At present, there are many types of car lights, and there are various lighting methods, and more functions are defined on car lights. As a warning light, the car brake light can accurately transmit the braking information of the car to the rear vehicles during driving. Existing automobile brake lights have only one brightness when they are lit, which cannot provide a better warning effect when the external light is sufficient, and increase the power consumption of the whole vehicle when the external light is insufficient. [0003] Most of the brake lights assembled in existing automobiles adopt LED lights. When the brake pedal is stepped on, the light or extinguishment of the brake lights is controlle...

AI Technical Summary

Problems solved by technology

However, the existing PWM only has the function of on and off, and cannot adjust the brightness of the brake light, that is, the brake light has only one brightness

The brightness of the brake light is the same during the day and at night, which can not better warn the vehicles behind when the outside light is sufficient during the day, and the brightness is too high at night when the light is insufficient, which increases the power consumption of the whole vehicle
