Abstract
The invention discloses a high level brake lamp system capable of being lightened by levels through a vehicle body controller, which comprises three groups of high level brake lamps and socket connectors of the high level brake lamps. Each socket connector of the high level brake lamp comprises three anode terminals and one cathode terminal, and the three anode terminals are jointed with the three groups of lamp circuits respectively. The high level brake lamps are divided into a plurality of groups of circuits controlled by different power supplies and are lightened by levels according to the braking situation. A first diode is connected in series between the second-level anode terminal and the first-level anode terminal; and a second diode is connected in series between the third-level anode terminal and the second-level anode terminal, so that when one lamp fails, if one level is powered, the lamp can be lightened. In the system, the vehicle body controller can control the lightening of lamps by different levels along with the change of the brake acceleration of a vehicle, so that the back vehicle can judge the magnitude of the brake acceleration of the front vehicle immediately and respond properly to avoid rear-end accidents.
Description
Technical field
The present invention relates to high-mount brake lamp, more particularly, is the high-mount brake lamp that braking by grades is lighted.Light by the classification of car body controller (BCM) control high-mount brake lamp.
Background technology
The high-mount brake lamp of automobile has the function that warning front vehicle front vehicles is being braked.Conventional high-mount brake lamp is that one-level is lighted, and front vehicle can not be according to the size of judging the front vehicles braking acceleration of lighting of brake lamp, especially on than dark situation and expressway, is prone to accidents.
Summary of the invention
For the size of the braking deceleration of pointing out the front vehicle front vehicles, the high-mount brake lamp classification is lighted, along with the variation of car brakeing acceleration/accel, not at the same level the lighting of car body controller (BCM) control lamp.Front vehicle just can be judged the size of front vehicles braking acceleration immediately, thereby makes suitable reaction.In addition,, also can light the warning front vehicle, thereby make suitable reaction because the instantaneous deceleration that road, vehicle faults itself even traffic accident cause when vehicle by what BCM judged deceleration/decel and controlled high-mount brake lamp.
To achieve these goals, the invention provides a kind of high-mount brake lamp system that lights by the car body controller classification, comprise three groups of high-mount brake lamp and high-mount brake lamp connector, the high-mount brake lamp connector comprises three positive terminals and a negative pole end, three positive terminals dock three groups of circuit for lamp respectively, high-mount brake lamp is divided into the circuit that several groups of different electrical power are controlled, and classification is lighted according to the braking situation.
When vehicle is common brake, the conducting of one-level circuit for lamp, the first not conducting of diode, first group of high-mount brake lamp and common brake lamp are lighted by the control of service brake switch.
When vehicle emergency brakes, car body controller collection vehicle acceleration signal, when acceleration/accel reaches the value that second group of high-mount brake lamp that car body controller sets light, the conducting of secondary circuit for lamp.
When the car brakeing acceleration/accel reaches the 3rd group of value that high-mount brake lamp is lighted of car body controller setting, three grades of circuit for lamp conductings of car body controller control, firsts and seconds circuit for lamp conducting this moment.
Further, between secondary positive terminal and one-level positive terminal, be connected in series first diode, be connected in series second diode between three grades of positive terminals and the secondary positive terminal, make that as long as there is one-level that electricity is arranged, lamp will be lighted when inefficacy appears in lamp.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is specifically described.
As shown in Figure 1, high-mount brake lamp is composed in parallel by the LED lamp, light up as example with three grades, circuit is divided into three groups, the light intensity unanimity of three groups of high-mount brake lamp, high-mount brake lamp connector are divided into 3 positive terminals and a negative pole end, and 3 positive poles dock 3 groups of circuit for lamp respectively, high-mount brake lamp is divided into the circuit that several groups of different electrical power are controlled, and classification is lighted according to the braking situation.
When vehicle was common brake, chaufeur was stepped on brake pedal, when vehicle deceleration less than BCM set light the deceleration value of second group of brake lamp the time (0.2-0.3g can demarcate, wherein g=9.8m/s
2), the conducting of one-level circuit for lamp, total current is 50mA, and diode D1 can not conducting, and first group of high-mount brake lamp L1 and common S1, S2 class brake lamp L0 light by the control of service brake switch, as shown in Figure 3.
When vehicle emergency brakes, BCM collection vehicle deceleration/decel signal, when deceleration/decel reaches the value that second group of high-mount brake lamp L2 that BCM sets light (0.2-0.3g can demarcate), two utmost point positive circuit conductings, one still conducting of utmost point positive circuit, two utmost point positive circuit electric currents are 50mA.If an extremely positive no-voltage, diode D1 conducting improves the bright reliability of a limit, as shown in Figure 4.
(greater than 0.5g, can demarcate) when the car brakeing acceleration/accel is bigger, BCM controls three utmost point positive circuit conductings, this moment one extremely just with two extremely just still conductings.Three utmost point positive circuit electric currents are 50mA.If two utmost point positive voltages are normal, not conducting of diode D2, if two extremely positive no-voltages, diode D2 conducting has improved the reliability of lamp.
In order to satisfy light distribution requirements, every section LED all makes single LEDs brightness reach requirement by the resistance of the different sizes of connecting, and finally satisfies the luminous intensity distribution value of rules.
So just light the length difference and warned front vehicle front vehicles braking acceleration situation, make it can make suitable reaction by high-mount brake lamp.
