Intelligent control device and method for automobile brake lamps, and automobile

Abstract

The invention discloses an intelligent control device and method for automobile brake lamps, and an automobile comprising the intelligent control device. The intelligent control device comprises a light sensor, a brake sensor and a controller, wherein the light sensor is used for detecting light intensity of an environment and outputting a light intensity signal; the brake sensor is used for outputting a brake signal when the condition that an automobile brake pedal is stepped on is detected; the controller is used for receiving the light intensity signal outputted by the light sensor and the brake signal outputted by the brake sensor, and controlling the brake lamps to emit light when the brake signal is received; the brightness of the brake lamps is determined by the controller according to the light intensity signal. The brake lamps are driven to show different brightness through judging different external illumination intensity in braking, the power consumption of the complete automobile is reduced while a better warning effect is achieved, and bad visual stimulation to a driver in a rear automobile is not caused. The intelligent control brake lamps are different in brightness, and other operations except for the brake pedal stepping on are not needed.

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
