Abstract
The invention discloses an intelligent slowing system for a vehicle. The intelligent slowing system comprises a slowing device, a radar and an electronic control system, wherein the radar comprises an antenna, a circulator and a mixer; and the electronic control system comprises an oscillator, an amplifying and shaping circuit and a digital processing circuit. The vehicle is automatically slowed through the radar and the electronic control system, and the gears of slowing are adjusted according to the distance between the vehicle and a front vehicle, so that impact force is lightened when a driver is too late to start the slowing device and the vehicle is collided with the front vehicle, an extraordinarily serious traffic accident is avoided, and the brake performance is improved.
Description
Technical field
The present invention relates to the car retardation technical field, relate in particular to a kind of vehicle slow system of intelligence.
Background technology
Automobile can steadily slow down slowing down or during lower long slope, enabling retarder, removes apply the brakes from and the wearing and tearing and the heating that cause.Common retarder is comprised of stator, rotor rotating disk, Control case and switch, stator is fixed on the vehicle chassis, rotor links together by bead and transmission shaft, very little air gap is arranged between rotor and the stator, after the master cock energising, the magnetic field that many groups coil in the stator and rotor produce produces huge moment and acts on the rotor rotating disk, and rotating speed of transmission shaft is slowed down.Thereby make car retardation.Common retarder has hand control switch or stretcher master cock, when starting hand control switch or stretcher master cock, chaufeur is in the situation that clear-headed or use in the preprepared situation, but, when vehicle in the situation that when running at high speed or chaufeur is clear-headed or energy is not concentrated, when chaufeur has little time to brake, if bump with obstacle, the bump dynamics can be very large, can cause the emission of especially big traffic accident.
Summary of the invention
The object of the invention is exactly in order to remedy the defective of prior art, a kind of vehicle that can automatically make the vehicle reducing speed that adopts the meter wave radar control technology to make slow system of intelligence to be provided.
The present invention is achieved by the following technical solutions:
A kind of vehicle slow system of intelligence, include retarder, also include radar and electronic control system, described radar includes antenna, circulator and frequency mixer, described electronic control system includes oscillator, amplification and rectification circuit and digital processing circuit, described antenna transmission also receives electromagnetic wave signal, and the electromagnetic wave signal with the place ahead obstacle distance information that will receive is transferred to circulator, described oscillator is carried oscillator signal to circulator, circulator transmits electromagnetic wave signal and oscillator signal simultaneously into frequency mixer, described frequency mixer is sent mixed signal into digital processing circuit behind amplification and rectification circuit, digital processing circuit carries out analyzing and processing with the signal that receives, draw the distance value of the place ahead obstacle, described digital processing circuit is connected with the master control system of described retarder, the distance value that digital processing circuit draws is delivered in the master control system of described retarder, and master control system is regulated the gear of retarder automatically according to the size of the distance value that receives.
Described digital processing circuit also is connected with selecting arrangement, can select other several functions, such as warning function.
Described digital processing circuit also is connected with a read out instrument.
Advantage of the present invention is: the present invention adopts radar and electronic control system to realize the automatically slow of vehicle, distance according to front vehicles is adjusted slow gear, chaufeur alleviates the bump dynamics having little time to start when retarder and front vehicles bump, avoid occuring especially big traffic accident, improved deceleration and stopping performance.
