Abstract
The invention aims at providing a control system and a control method for an automobile brake lamp so as to prompt the brake situation of an automobile to a vehicle behind in more detail and automatically prompt the vehicle behind of rear end collision danger when the distance from the vehicle behind to the automobile is smaller than the preset distance. The control system for the automobile brake lamp comprises the brake lamp and a control unit for controlling the brake lamp to work, wherein the control unit is connected with a brake sensor for detecting brake pedal travel and the key characteristic is that the control unit is also connected with a speed sensor and a radar probe used for detecting the distance from the vehicle behind to the automobile. The control unit utilizes the radar probe to detect the distance L from the vehicle behind to the automobile and the automobile sensor to detect the current speed V of the automobile; when L is smaller than the safe distance LA which the current speed V corresponds to, the control unit controls the brake lamp to flash with preset frequency; and the safe distance LA is looked up from a table according to the current speed V.
Description
Technical field
The invention belongs to automotive lighting control field, be specifically related to a kind of control system and control method thereof of automobile brake lamp.
Background technology
Automobile brake lamp is that other use the road person to show the light fixture that vehicle is being braked to rear view of vehicle; Self-opening when the driver steps on brake pedal; Function is comparatively single; Can not be non-emergency braking or emergency braking when the rear view of vehicle driver shows car brakeing more carefully, also not possess according to the distance of vehicle and rear running distance and the warning function of the rear end collision of vehicle prompting rearward.
Summary of the invention
The objective of the invention is to propose a kind of control system and control method thereof of automobile brake lamp; With the braking situation of this car of vehicle prompting rearward in more detail, and when the distance between vehicle and this car is less than preset distance in the wings automatically rearward vehicle point out rear end collision.
The control system of automobile brake lamp of the present invention comprises the control unit of brake lamp and the work of control brake lamp; Said control unit links to each other with the braking sensor of surveying brake-pedal travel, key be said control unit also respectively with car speed sensor, be used to survey between front vehicle and this car the radar of distance and pop one's head in and link to each other.
The control method of the control system of above-mentioned automobile brake lamp is following: control unit utilizes braking sensor to survey the stroke of brake pedal, and when brake pedal was stepped on, control unit control brake lamp was lighted; Key is that said control unit also comprises warning function; Said warning function comprises the steps: A: control unit utilizes the distance L between radar probe detection front vehicle and this car; And utilize car speed sensor to survey the current vehicle speed V of this car; As L during less than the pairing safety distance LA of current vehicle speed V, control unit control brake lamp glimmers according to preset frequency, and said safety distance LA tables look-up according to current vehicle speed V and obtains.Through warning function, vehicle and this spacing are crossed when near in the wings, and rearward vehicle is pointed out rear end collision automatically, thereby has improved safety factor of travel.
Further, said control unit links to each other with an acceleration pick-up, with better rearward vehicle warn.Compare above-mentioned control method; After having acceleration pick-up; Its warning function also comprises the steps: B: control unit utilizes acceleration pick-up to survey the acceleration/accel a of this car; As the acceleration/accel a of this car during less than predetermined acceleration a0, control unit control brake lamp is according to preset frequency Chang Liang after the flicker schedule time, and said acceleration/accel a0 is less than 0.
Further; Said brake lamp is made up of a plurality of LED; With the braking situation of this car of vehicle prompting rearward better; The method of concrete prompting is following: in the above-mentioned B step, as the acceleration/accel a of this car during less than predetermined acceleration a0, control unit control brake lamp is lighted the whole LED in the brake lamp according to preset frequency after the flicker schedule time; When the acceleration/accel a of this car greater than predetermined acceleration a0 and less than 0 the time, the partial L ED in the brake lamp is lighted in control unit control.When being emergency braking; Brake lamp is all lighted and is glimmered; Non-emergent glancing impact brake lamp normally continues to light; And brake lamp indication area is the part of whole brake lamp brightness area but not all, can let the rear driver can differentiate this car like this is non-emergency braking or emergency braking, thereby more effectively prevents the generation of rear-end collision accident.
Further; In the control method of the control system of above-mentioned automobile brake lamp; Have only as current vehicle speed V during greater than predetermined minimum speed V min; Control unit is just opened warning function, the rear end collision when preventing high speed traveling so emphatically, and needn't safety higher drive at low speed the time frequently light brake lamp.
The control system of automobile brake lamp of the present invention is simple in structure; Its control method is rationally effective; Can be in more detail the braking situation of this car of vehicle prompting rearward; And the rear end collision of vehicle prompting rearward automatically when the distance between vehicle and this car is less than preset distance in the wings, thereby improved safety factor of travel.
Description of drawings
Fig. 1 is the schematic diagram of the control system of automobile brake lamp of the present invention.
The specific embodiment
