Abstract
The invention relates to a control device for an automobile brake lamp and a control method thereof. During the emergency braking of an automobile, the control device for the automobile brake lamp can make the brake lamp be in a display status under an emergency braking state. The technical proposal is as follows: the control device for the automobile brake lamp is provided with a main braking cylinder and an entire automobile ECU; and the control device is characterized in that a pressure sensor is arranged on the main braking cylinder; the signal output end of the pressure sensor is connected with the entire automobile ECU; and the entire automobile ECU controls the display status of the brake lamp according to the signal sent by the pressure sensor.
Description
Technical field
The present invention relates to a kind of braking automobile lamp control device and control method thereof.
Background technology
The orthodox car hydraulic braking is that the power amplification that chaufeur is applied on the brake pedal is reflected to master brake cylinder, sets up the pressure of whole brake piping by master brake cylinder, thereby promotes the braking that each drg is realized car load.In the whole process of braking, the stoplight stop lamp of car load is in illuminating state, so that remind the automobile of back to prevent the generation of rear-end collision.There is certain defective in the warning of stoplight stop lamp, such as, on express highway, drive, when front truck braking (stoplight stop lamp gives a warning), generally speaking, back car chaufeur judges by the velocity attenuation (or the distance in two workshops sharply reduces) of front truck whether front truck has taked emergency braking; If the back car does not know that front truck taked emergency braking, deal with improperly, easily cause danger.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of braking automobile lamp control device and control method thereof, and at the automobile emergency glancing impact, stoplight stop lamp is in the show state under the emergency braking condition.
Order of the present invention has two independent technique schemes based on same inventive concept:
1, a kind of braking automobile lamp control device, have main brake cylinder, car load ECU, it is characterized in that: pressure sensor is housed on main brake cylinder, pressure sensor signal output termination car load ECU, car load ECU controls the stoplight stop lamp show state according to the signal that pressure sensor transmits.
Stoplight stop lamp is connected to flasher, the signal output relay termination of car load ECU, the break-make of this relay control storage battery and flasher, stoplight stop lamp circuit series.
2, a kind of control method of aforementioned braking automobile lamp control device is characterized in that: when being in an emergency, when stepping on slipper suddenly, pressure sensor is sent to car load ECU with pressure signal, after the car load ECU identification, directly stoplight stop lamp is controlled, made it be in the emergency brake show state.
Behind the car load ECU identified emergency brake pressure signal, it is flasher, stoplight stop lamp power supply that control relay makes storage battery, makes stoplight stop lamp be in the emergency brake show state of flicker.
The beneficial effect that the present invention has:
The present invention can realize that stoplight stop lamp ceaselessly glimmers when the automobile emergency glancing impact, and the easier people of making discerns, and makes judgement; The present invention is simple in structure, is easy to realize that dependable performance effectively improves vehicle safety performance.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
As shown in the figure, main brake cylinder 2, car load ECU 6, on main brake cylinder 2 (or main brake pipeline), pressure sensor 1 is housed, pressure sensor signal output termination car load ECU 6, car load ECU controls the stoplight stop lamp show state according to the signal that pressure sensor transmits.
Car load ECU realizes the stoplight stop lamp show state is controlled by following structure: stoplight stop lamp 3 is connected to flasher 8, the signal output relay termination 7 of car load ECU, the break-make of this relay control storage battery 5 and flasher 8, stoplight stop lamp 3 circuit seriess.
When being in an emergency, when stepping on slipper 4 suddenly, braking force is big more at ordinary times to be applied to power on the pedal, and according to Pascal's law, the power that chaufeur is applied on the slipper 4 will be amplified on the main brake cylinder 2 (and main brake pipeline) at double.Pressure sensor 1 is sent to car load ECU 6 with pressure signal, behind the car load ECU identified emergency brake pressure signal, control relay 7 makes storage battery 5 be flasher 8, stoplight stop lamp 3 power supplies, stoplight stop lamp is lighted and is begun fast blink, play the purpose of emergency situation warning, guarantee the car load driving safety.
Claims (4)
1, a kind of braking automobile lamp control device, have main brake cylinder, car load ECU, it is characterized in that: pressure sensor is housed on main brake cylinder, pressure sensor signal output termination car load ECU, car load ECU controls the stoplight stop lamp show state according to the signal that pressure sensor transmits.
2, braking automobile lamp control device according to claim 1, it is characterized in that: stoplight stop lamp is connected to flasher, the signal output relay termination of car load ECU, the break-make of this relay control storage battery and flasher, stoplight stop lamp circuit series.
3, the control method of the described braking automobile lamp control device of a kind of claim 1, it is characterized in that: when being in an emergency, when stepping on slipper suddenly, pressure sensor is sent to car load ECU with pressure signal, after the car load ECU identification, directly stoplight stop lamp is controlled, made it be in the emergency brake show state.
4, the control method of braking automobile lamp control device according to claim 3, it is characterized in that: stoplight stop lamp is connected to flasher, the signal output relay termination of car load ECU, the break-make of this relay control storage battery and flasher, stoplight stop lamp circuit series; Behind the car load ECU identified emergency brake pressure signal, it is flasher, stoplight stop lamp power supply that control relay makes storage battery, makes stoplight stop lamp be in the emergency brake show state of flicker.
