Abstract

The invention provides an intelligent signal lamp for automobiles comprising a MCU and a LED lattice. The LED lattice is composed of a plurality of high brightness LEDs integrating three colors of red, yellow and green. Each LED which is a high brightness LED sold in markets is connected with an I/O interface of the MCU and is arranged in the sequence of red, yellow and green from left to right on the tailstock of a vehicle. The acquired speed signals are input into the MCU, analyzed and judged by the MCU to control LED display, thereby vehicle speeds are displayed in real time. The vehicle speed is displayed by the colors and numbers of the LEDs, and the LEDs can also be used with a high position braking lamp in combination. The inventive intelligent signal lamp is provided with low power consumption, high reliability and intelligentization, shortens vehicle following distance, and reduces rear collision probability. Low production cost and large market potential are also provided.

Description

A kind of intelligent signal lamp for automobile
Affiliated field:
The present invention relates to a kind of Vehicular lamp, specifically a kind of intelligent automobile signal lamp.
Background technology:
Automobile lamp mainly is divided into lighting and signal lamp according to function of use.Lighting is that travel, traffic sign, other vehicles, pedestrian etc. are thrown light on.Signal lamp is the information that shows the existence of vehicle and pass on vehicle running state.
In the prior art, the speed of a motor vehicle all is to be shown to oneself to see, and other road user is difficult to estimate the speed of a motor vehicle of oneself, especially when everybody all when running at high speed.Can make troubles to the driver's of back operation like this.When dense fog, other road user is difficult to declare the vehicle existence and the transport condition of road ahead.
Summary of the invention:
The objective of the invention is when making the driver driving motor vehicle safer and grasp the vehicle existence of road ahead and transport condition at any time and a kind of intelligent signal lamp for automobile of designing.
The present invention is made of single-chip microcomputer, LED dot matrix; The LED dot matrix is by a plurality of high brightness, and the LED that to collect red, yellow, green three kinds of colors be one forms, and LED is connected with the I/O mouth of single-chip microcomputer respectively; LED1~LED4 is red; LED5~LED8 is yellow; LED9~LED12 is green; Every bright LED represents the speed of 10km/h, speed from low to high, the color of LED correspondence is followed successively by redness, yellow, green; The LED of shiny red represents that vehicle speed range is 0km/h~40km/h; Jonquilleous LED represents that vehicle speed range is 40km/h~80km/h; The LED of bright green represents that vehicle speed range is 80km/h~120km/h; LED is commercially available high-brightness LED; Be installed in the tailstock, in one line from left to right by red, yellow, green order; Color, number with LED show current vehicle speed.
The number of LED, can increase as required or reduce; Color also can be decided as required.
GES is to utilize vehicle speed sensor on the car by the timer collection of single-chip microcomputer, also can by the CAN bus on the car or the LIN bus obtain; With the rate signal input single-chip microcomputer of gathering, by the single-chip microcomputer analysis, judge, and the demonstration of control LED.
Signal lamp can be used in combination with the high-mount brake lamp on the former motor vehicle, also can replace the high-mount stop lamp of automobile.
Beneficial effect of the present invention is as follows:
(1) low-power consumption.The current drain of LED is low, and the capacity usage ratio height, and it is little to dispel the heat, environmental protection and energy saving.
(2) highly reliable.Can bear high-intensity oscillation and impact, be applicable to the use vehicle condition of Automobile Complex; Technology is simple, and the life-span is long, freedom from repairs; LED shows that control is simple; Environmental adaptability is strong; A plurality of LED parallel connections, installation difficulty is low.
(3) safe.System response time is fast, and the response time of general LED is several nanoseconds, and can realize the demonstration constantly of the speed of a motor vehicle, can prevent the generation of rear-end collision.
(4) easy for installation.The vehicle speed sensor that system is used has on the automobile now, need not add.System can read institute by the bus on the car must data.
(5) cost is low.The cost of whole system is no more than hundred yuan, and market application foreground is extensive.
(6) native system also can replace the high-mount stop lamp of automobile.
Description of drawings
Fig. 1-be the control principle figure of intelligent signal lamp for automobile;
Fig. 2-be the internal circuit connection layout, 12 LED respectively with the PTA0~PTA7 of single-chip microcomputer, eight I/O mouths of PTD0~PTD3 connect; 12 LED are commercially available high-brightness LED.
Specific embodiments
The invention will be further described below in conjunction with drawings and Examples:
The present invention is made of single-chip microcomputer, LED dot matrix; The LED dot matrix is by 12 high brightness, and the LED that to collect red, yellow, green three kinds of colors be one forms, 12 LED respectively with the PTA0~PTA7 of single-chip microcomputer, eight I/O mouths of PTD0~PTD3 connect; LED is commercially available high-brightness LED; Be installed in the tailstock, in one line from left to right by red, yellow, green order; Color, number with LED show current vehicle speed, and the present invention and high-mount brake lamp are used in combination.
The present invention, judges by the single-chip microcomputer analysis according to the rate signal of gathering, and the demonstration of control LED, thereby shows the speed of a motor vehicle in real time.
GES is to utilize vehicle speed sensor on the car by the timer collection of single-chip microcomputer, obtains by the CAN bus.Thereby single-chip microcomputer obtains will analyze, judge the demonstration of controlling LED behind the GES.
As shown in Figure 2, used LED lamp is connected on the I/O mouth of single-chip microcomputer (A, B, four interfaces of C, D all right).LED1~LED4 is red; LED5~LED8 is yellow; LED9~LED12 is green.Every bright LED represents the speed of 10km/h, speed from low to high, the color of LED correspondence is followed successively by redness, yellow, green; The LED of shiny red represents that vehicle speed range is 0km/h~40km/h; Jonquilleous LED represents that vehicle speed range is 40km/h~80km/h; The LED of bright green represents that vehicle speed range is 80km/h~120km/h (the number color of LED can increase or reduce as required).
