Description
Technical Field
The utility model relates to the technical field of auto-parts, refer in particular to an early warning brake lamp in advance.
Background
Each automobile is provided with a brake lamp, and as long as a driver steps on a brake, the brake lamp at the rear part can be immediately turned on so as to prompt the rear part to keep a distance to the coming automobile to avoid collision and protect safety. However, the performance of the existing vehicles is better and better, almost all roads are driven at the highest speed, and whether many drivers drive at the safe distance, for example, when the vehicle speed is 60 kilometers, the vehicles move by 16.7 meters per second, if one vehicle suddenly stops or decelerates, and the vehicle coming from behind needs to react and stop for 1.5 seconds, the rear vehicle needs to have a distance of 25 meters to avoid, which is the importance of the safe distance, if the distance is enough to frighten one, otherwise, the situation happens.
SUMMERY OF THE UTILITY MODEL
To above problem, the utility model provides an early warning brake lamp in advance reflects the action of will slowing down to brake lamp in advance, and the suggestion is detained the side and is arrived car in advance, extension reaction time to ask to obtain safe distance mutual protection.
In order to achieve the above purpose, the utility model discloses the technical scheme who uses as follows:
the early warning brake lamp comprises a speedometer speed signal input, a foot brake signal input, a hand brake signal input, a microprocessor and a brake lamp, wherein the speedometer speed signal input, the foot brake signal input and the hand brake signal input are respectively and electrically connected with the microprocessor, the microprocessor is electrically connected with the brake lamp, and the microprocessor is electrically connected with an automobile power supply through a power supply voltage stabilizing circuit.
According to the scheme, the microprocessor is a single-chip microcomputer processing unit, and the single-chip microcomputer processing unit is provided with 4 reliable-input dip switches.
The utility model discloses beneficial effect:
1) the speed is input and judged through the speedometer speed signal of the device, the brake lamp is turned on before the driver steps on the brake, the reaction time of 0.1-2 seconds is provided for the coming vehicle behind, the time for parking or dodging is increased, the traffic accident can be avoided, and the disaster degree is at least reduced;
2) the device is characterized in that the device is provided with a brake lamp which is turned off when the vehicle speed is reduced, the device can give 0.2-2 seconds of reaction time for the coming vehicle, increase the time for parking or dodging, avoid traffic accidents and at least reduce the disaster degree.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
Detailed Description
The technical solution of the present invention will be described below with reference to the accompanying drawings and examples.
As shown in FIG. 1, an early warning brake lamp in advance, including odometer speed signal input, foot brake signal input, hand brake signal input, microprocessor and brake lamp, odometer speed signal input, foot brake signal input and hand brake signal input electricity respectively connect in microprocessor, and the microprocessor electricity is connected in the brake lamp, and microprocessor passes through the power voltage stabilizing circuit electricity and connects in the automobile power. By adopting the structure, the speedometer inputs a speedometer speed signal, inputs a foot brake signal and inputs a hand brake signal to the microprocessor, and then the microprocessor continuously judges the mileage input signal, so that the speed of the vehicle can be calculated, when the speed of the vehicle is reduced by 10KM/H, the vehicle is considered to be suddenly decelerated, the brake lamp is controlled to be lightened immediately, meanwhile, the foot brake signal input and the hand brake signal input are read, one of the foot brake signal input and the hand brake signal input has action, the brake lamp is controlled to be lightened immediately, the brake lamp is used for controlling output, the control signal of the microprocessor is received and is lightened immediately, the time for parking or dodging is prolonged, the occurrence of traffic accidents can be avoided, and the disaster.
In practical application, the device can automatically judge that the vehicle is decelerated and lightened in advance, the time of more than 0.2 second is given to a vehicle coming from the rear, the vehicle speed difference is calculated as 20 kilometers, and the vehicle is sufficiently lengthened by 20KM/60/60 x 0.2 to 1.1 meters, so that a tragedy is possibly prevented from happening, and the disaster degree is at least reduced.
The test steps of the device are as follows:
1) for judging the input of a speedometer speed signal, a pulse is provided for each revolution of a common wheel, 111 centimeters (14 × 2.54 × 3.14) is calculated for each revolution by using a tire with the diameter of 14 inches, if the speed per hour is 60 kilometers, the moving distance per second is 16.67 meters, 14.91 revolutions are transferred in one second, and the time per revolution is 67.03 milliseconds;
2) calculating the average value of every eight circles, comparing the average value with the value of the last circle, and controlling the brake lamp to light as long as the time is more than 10% of the average value, and the brake lamp can be regarded as being in the normal hall and suddenly dropping in the vehicle;
3) meanwhile, hand and foot braking signals are detected, and one of the signals has an action to immediately control the brake lamp to light.
In this embodiment, the microprocessor is a single chip processing unit, and the single chip processing unit is provided with 4 reliable finger-dialing switches. With such a configuration, since the tire height affects the determination of the speedometer speed signal input in relation to the size of the rim, the tire height needs to be known.
The tire height is tire width aspect ratio 2+ rim diameter 25.4 (unit: mm), for example 195/65R15 tire height is 195 0.65 2+15 25.4 is 634.5mm, so the microprocessor has 4 input reliable dip switches to select, and the 4 input reliable dip switches can be matched with proper value according to the tire size, and the diameter can be graded from 50 to 130CM, and the microprocessor is suitable for small minibus to large truck.
The embodiments of the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, and these forms are within the scope of the present invention.
