Detailed description of the invention
Below in conjunction with preferred embodiment, the present invention is described in further details; set forth in the following description more details so that fully understand the present invention; but; the present invention obviously can implement in multiple other modes that are different from this description; those skilled in the art can do similar popularization, deduction according to practical situations without prejudice to intension of the present invention in the situation that, therefore should be with content constraints protection scope of the present invention of this specific embodiment.
We find through a large amount of testing researches: reach >=3m/s of braking acceleration2Time, belong to and bring to a halt, dangerous to rear car, if rear car driver can not react in time, easily cause rear-end collision, should note in very first time special suggestion rear car, we are definition >=3m/s2Braking acceleration be the braking of bringing to a halt.
We also find: as braking acceleration≤2m/s2Time, rear car is safe from danger substantially, brake lamp is bright, without special suggestion. Work as 2m/s2≤ braking acceleration < 3m/s2Time, belong to hard braking, now preferably point out rear car, make rear car also follow braking, but must not bring to a halt, note a little, we define 2m/s2≤ braking acceleration < 3m/s2The braking acceleration skidding of attaching most importance to.
Fig. 1 is the schematic diagram of a theory diagram of the present invention, and Fig. 2 is the schematic diagram of one embodiment of the present of invention.
Embodiment mono-, a kind of intelligent signal lamp for automobile, comprise brake switch, braking strength sensor, controller, high-mount stop lamp, brake lamp and braking strength indicator lamp, braking strength indicator lamp is positioned at high-mount stop lamp both sides, brake switch is connected with controller, braking strength sensor is connected with controller, controller is connected with high-mount stop lamp, controller is connected with brake lamp, controller is connected with braking strength indicator lamp, high-mount stop lamp by controller according to the output signal control of the output signal of brake switch and braking strength sensor, braking strength indicator lamp by controller according to the output signal control of braking strength sensor.
Wherein, this braking strength sensor is brake pedal position sensor, brake pedal force sensor or acceleration transducer, and controller is according to the light on and off of the output signal control high-mount stop lamp of brake pedal position sensor, brake pedal force sensor or acceleration transducer and braking strength indicator lamp.
When in the present embodiment, braking strength sensor adopts brake pedal position sensor or brake pedal force sensor, there is one-to-one relationship in pedal position and braking acceleration, the 0-5V voltage signal of brake pedal position sensor or the output of brake pedal force sensor or 4-20mA current signal correspondence corresponding car brakeing accekeration, and controller is converted into the braking acceleration value of data signal according to the output signal of brake pedal position sensor or brake pedal force sensor. Because brake pedal position is unique corresponding with braking acceleration, therefore, adopt brake pedal position sensor or brake pedal force sensor to correct without sensor output signal being done to acceleration initial value.
In the time that braking strength sensor adopts acceleration transducer, because Vehicle Driving Cycle brief acceleration sensor on acclive road can, because change and produce signal output with ground angle, therefore need that acceleration sensor outputs signals is done to acceleration initial value and correct: controller degree of will speed up sensor output value changes data signal into. In the time that brake switch is closed, the initial acceleration value of controller using the accekeration record of closed moment of brake switch as vehicle, the acceleration output valve of follow-up measurement deducts initial acceleration value and obtains the real braking acceleration value of vehicle. Controller is according to the light on and off of braking acceleration value control high-mount stop lamp, brake lamp and braking strength indicator lamp.
Controller is according to the light on and off of the brake switch signal of vehicle and braking acceleration value control braking strength indicator lamp. In the time that brake switch is closed, high-mount stop lamp, brake lamp are lighted, and in the time that brake switch disconnects, high-mount stop lamp, brake lamp extinguish; In the time of the high value of braking acceleration value >=hard braking threshold value, braking strength indicator lamp is lighted, in the time of braking acceleration value < hard braking threshold value low value, braking strength indicator lamp extinguishes, the high value of hard braking threshold value and hard braking threshold value low value form Schmidt trigger, and can prevent hard braking time, brake indicating lamp mistake is dodged; In the time of braking acceleration value >=bring to a halt threshold value, high-mount stop lamp, brake lamp, braking strength indicator lamp are lighted and with 4-5Hz frequency scintillation simultaneously; When braking acceleration < brings to a halt after threshold value, the flicker of high-mount stop lamp, brake lamp, braking strength indicator lamp stops after maintaining 1-3 second.
According to repeatedly actual test, the high value scope of hard braking threshold value is 1.7m/s2～2.3m/s2, hard braking threshold value low value scope is 1.0m/s2～1.8m/s2, the threshold value of bringing to a halt span is 2.5m/s2～3.9m/s2, alarming effect is comparatively desirable.
In the time that used car is transformed, some vehicle only has brake lamp, there is no high-mount stop lamp; Some vehicle braking lamp and other indicator lamps are combined into one, and cannot control separately; Also utilize former vehicle device for convenience of wiring as far as possible, according to former car situation, controller output can only connect high-mount stop lamp, or only connect brake lamp, or only connect high-mount stop lamp and brake lamp, and do not connect braking strength indicator lamp, now this intelligent signal lamp can only be indicated brake and two states of bringing to a halt, though indicating effect is slightly poor, the crucial deixis of bringing to a halt still has higher safe value.
Above content is the explanation of the preferred embodiment to the invention, can help those skilled in the art to understand more fully the technical scheme of the invention. But these embodiment only illustrate, can not assert that the detailed description of the invention of the invention only limits to the explanation of these embodiment. Concerning the invention person of an ordinary skill in the technical field, without departing from the concept of the premise of the invention, can also make some simple deductions and conversion, all should be considered as belonging to the protection domain of the invention.
