Described wheel speed sensors is used for the monitoring wheel tach signal;
Described LED high-mount brake lamp comprises high-mount brake lamp turn sign zone, hypervelocity voice alarm device and high-mount brake lamp digital signal zone,
Described high-mount brake lamp turn sign zone is by lighting or the steering direction of this regional led array with the expression automobile that glimmer;
Described hypervelocity voice alarm device is used to the audio alert that exceeds the speed limit;
Described high-mount brake lamp digital signal zone is used for the current state of display automobile;
Described embedded ECU (Electrical Control Unit) is connected by the same braking sensor of vehicle-mounted CAN bus, rotation direction sensor, reversing sensor and wheel speed sensors and obtains the current state information of automobile; High-mount brake lamp turn sign zone in the described LED high-mount brake lamp, hypervelocity voice alarm device are connected with embedded ECU (Electrical Control Unit) by data line with LED lamp in the high-mount brake lamp digital signal zone.When the reversing sensor was passed astern signal back, the led array in embedded ECU (Electrical Control Unit) control high-mount brake lamp digital signal zone showed " R " and flicker.
Effect of the present utility model and benefit are: enriched the function of traditional high-mount brake lamp, the perfect deficiency of existing car lamp control system.High-mount brake lamp shows the speed of a motor vehicle in braking, for the rear automobile provides speed of a motor vehicle reference information, can effectively reduce the occurrence probability of rear-end collision; Turn to and when moveing backward, signal area display reminding information can fully show motoring condition; The hypervelocity sound prompt function can effectively be reminded the chaufeur control speed of a motor vehicle, improves traffic safety; This system combines that the LED energy consumption is low, anti-vibration, life-span are long, light rapidly and advantage that can self-defined layout.In addition, the composition of this system is simple in structure, is convenient to produce, and with low costly is suitable for extensive popularization.
Description of drawings
Fig. 1 is the structural representation of system described in the utility model;
The specific embodiment
LED high-mount brake lamp intelligence control system as shown in Figure 1 based on the CAN bus, it is characterized in that comprising LED high-mount brake lamp 2, embedded ECU (Electrical Control Unit) 5, braking sensor 7, rotation direction sensor 8, reversing sensor 9 and wheel speed sensors 10, braking sensor 7 is used to monitor automobile brake signal, rotation direction sensor 8 is used to monitor the motor turning signal, reversing sensor 9 is used to monitor the reversing automobile signal, wheel speed sensors 10 is used for the monitoring wheel tach signal, LED high-mount brake lamp 2 comprises high-mount brake lamp turn sign zone 1, hypervelocity voice alarm device 3 and high-mount brake lamp digital signal zone 4, high-mount brake lamp turn sign zone 1 by light or this regional led array that glimmers with the steering direction of expression automobile, hypervelocity voice alarm device 3 is used to the audio alert that exceeds the speed limit; High-mount brake lamp digital signal zone 4 is used for the current state of display automobile; Embedded ECU (Electrical Control Unit) 5 is connected with braking sensor 7, rotation direction sensor 8, reversing sensor 9 and wheel speed sensors 10 by vehicle-mounted CAN bus 6 and obtains the current state information of automobile; High-mount brake lamp turn sign zone 1 in the described LED high-mount brake lamp 2, hypervelocity voice alarm device 3 are connected with embedded ECU (Electrical Control Unit) 5 by data line with LED lamp in the high-mount brake lamp digital signal zone 4.
Wherein embedded ECU (Electrical Control Unit) 5 is obtained the automobile brake signal that braking sensor 7 is passed back by vehicle-mounted CAN bus 6, the motor turning signal that rotation direction sensor 8 is passed back, the vehicle wheel rotational speed signal that reversing automobile signal that reversing sensor 9 is passed back and wheel speed sensors 10 are passed back, thereby the current state of acquisition automobile: when the led array in the effective embedded ECU (Electrical Control Unit) of speed-slackening signal 5 control high-mount brake lamp digital signal zones 4 is lighted; After the effective embedded ECU (Electrical Control Unit) 5 of turn sign was judged steering direction, the led array in the high-mount brake lamp digital signal zone 4 of control respective direction was lighted or is glimmered; When the led array in the effective embedded ECU (Electrical Control Unit) of astern signal 5 control high-mount brake lamp digital signal zones 4 show that reversing indicates as: demonstrate letter " R " and flicker; Embedded ECU (Electrical Control Unit) 5 converts the vehicle wheel rotational speed signal to vehicle speed signal simultaneously, and the upper limit threshold of vehicle speed signal and embedded ECU (Electrical Control Unit) 5 inner settings is compared computing, if the speed of a motor vehicle is higher than threshold value, then control hypervelocity voice alarm device 3 is reported to the police.When the led array in the effective embedded ECU (Electrical Control Unit) of speed-slackening signal 5 control high-mount brake lamp digital signal zones 4 was lighted, embedded ECU (Electrical Control Unit) 5 control high-mount brake lamp digital signal zones 4 showed current vehicle speed.The mode that described embedded ECU (Electrical Control Unit) 5 control hypervelocity voice alarm devices 3 are reported to the police is for reporting to the police once every three minutes, if embedded ECU (Electrical Control Unit) 5 gets access to speed of a motor vehicle decline and is lower than threshold value, alarm automatically terminates, and is higher than threshold value once more until the speed of a motor vehicle and reports to the police once more.After chaufeur was closed hypervelocity voice alarm device 3, hypervelocity voice alarm device 3 quit work.When astern signal and speed-slackening signal simultaneously effectively the time, the led array in embedded ECU (Electrical Control Unit) 5 control high-mount brake lamp digital signal zones 4 shows " R " and flicker.
