Abstract
The invention belongs to the automobile safety field and in particular relates to an automobile deceleration safety system. The automobile deceleration safety system comprises a tail light for prompting a vehicle behind the vehicle; a buzzer for reminding of a driver; an accelerometer for detecting the accelerated speed of the vehicle; a gyroscope for detecting the pitch angle of the vehicle; a millimeter-wave radar for detecting the quantity, position, distance and speed of vehicles behind the vehicle; and a controller for processing information from all units and a sensor and generating control information. When the vehicle running at a high speed has a small opening degree of an accelerator pedal and a brake pedal is not treaded, a vehicle behind the vehicle cannot observe the deceleration of the vehicle easily. According to the potential risk, the automobile deceleration safety system is designed and has relatively high universality and reliability.
Description
Technical field
The invention belongs to field of automobile safety, be specifically related to a kind of automobile deceleration safety system.
Background technology
Along with the development of social economy's level, automobile also starts to enter huge numbers of families, become a kind of capital consumption product from initial luxury goods, recoverable amount is increasing, the competition of automobile vendor is also more and more fierce, consumer is also more and more higher for requirement and the expectation of automobile, especially security requirement is particularly paid attention to. In the time that the automobile of running at high speed unclamps gas pedal or accelerator open degree and reduces, but do not touch on the brake again pedal, at this moment the speed of automobile reduces. Due to the pedal that do not touch on the brake, so at this moment automobile tail light does not work, front vehicle cannot notice that this car slows down. Easily cause security incident, vehicle and personnel are damaged.
Summary of the invention
Object of the present invention is exactly the deficiency existing for above-mentioned background technology, and a kind of simple in structure, automobile deceleration safety system that reliability is strong is provided.
The problem that the present invention is directed to above-mentioned existence is mainly solved by following technical proposals.
A kind of automobile deceleration safety system, comprises tail-light, accelerometer, gyroscope, alarm controller, millimetre-wave radar, buzzer, it is characterized in that.
Accelerometer, for obtaining the acceleration of automobile; Gyroscope, for obtaining the angle of pitch of automobile; Alarm controller, processes the information that each unit and sensor transmit, and produces control information; Millimetre-wave radar, quantity, position, speed and the distance of detection automobile front vehicle; Buzzer, crosses when near apart from this car when front vehicle, and driver is sent to prompting.
Described alarm controller comprises primary processor, and the power module being connected with primary processor respectively, light flash module, the signal processing module one of phonetic warning module and processing MMW RADAR SIGNAL USING, process the signal processing module two of accelerometer signal, process the signal processing module three of gyroscope signal, described light flash module is electrically connected with tail-light, described phonetic warning module is electrically connected with buzzer, described signal processing module one is electrically connected with millimetre-wave radar, described signal processing module two is electrically connected with accelerometer, described signal processing module three is electrically connected with gyroscope.
Described accelerometer is arranged on automobile chassis, direction is along automobile Y-axis (automobile direction of advance), signal is sent to signal processing module two, calculated the acceleration in Y direction (automobile direction of advance) of vehicle by signal processing module two, and send to primary processor.
Be arranged on to described gyrohorizon automobile chassis. Signal is sent to signal processing module three, calculated the angle of pitch of vehicle by signal processing module three, call in order to primary processor.
Described millimetre-wave radar is arranged on automobile tail. Signal is sent to signal processing module one, calculated the quantity of front vehicle by signal processing module one, position, distance and speed, call in order to primary processor.
Described buzzer adopts passive buzzer.
The present invention arranges accelerometer, gyroscope, millimetre-wave radar and alarm controller, and in non-climbing state, driver upwards lifts gas pedal, but when not touching on the brake again pedal, situation is glimmered by tail-light, informs front vehicle, and this car slows down. If front vehicle is not slowed down, and very near apart from this car time, remind driver by buzzer. If automobile is in climbing state, system will not controlled tail-light flicker, prevent mistake alarm. The present invention is particularly applicable on expressway, and the security that greatly improves vehicle has stronger versatility and reliability.
