Abstract
The invention discloses the slow system of a kind of vehicle 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, the present invention adopts radar and electronic control system to realize the automatically slow of vehicle, slow gear is adjusted according to the distance of front vehicles, chaufeur alleviates shock dynamics when having little time startup retarder and front vehicles collides, avoid especially big traffic accident occurs, improve deceleration and stopping performance.
Description
Technical field
The present invention relates to car retardation technical field, particularly relate to the slow system of a kind of vehicle intelligence.
Background technology
Automobile slow down or lower long slope time, enable retarder, can steadily slow down, remove apply the brakes from and the wearing and tearing that cause and heating.Common retarder is made up of stator, rotor rotating disk, Control case and switch, stator is fixed on vehicle chassis, rotor is linked together by bead and transmission shaft, very little air gap is had between rotor and stator, when after master cock energising, the magnetic field that many groups coil in stator and rotor produce produces huge moment and acts on rotor rotating disk, and rotating speed of transmission shaft is slowed down.Thus make car retardation.Common retarder has hand control switch or stretcher master cock, when starting hand control switch or stretcher master cock, chaufeur uses when clear-headed or in preprepared situation, but, when vehicle is when running at high speed or chaufeur is not clear-headed or energy is not concentrated, when chaufeur has little time brake, if collided with obstacle, shock dynamics can very large, can cause the transmitting of especially big traffic accident.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of slow system of vehicle intelligence that automatically can make vehicle reducing speed adopting meter wave radar control technology to make.
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 preceding object thing range information received is transferred to circulator, described oscillator carries oscillator signal to circulator, electromagnetic wave signal and oscillator signal transmit into frequency mixer by circulator simultaneously, mixed signal is sent into digital processing circuit by described frequency mixer after amplification and rectification circuit, the signal received is carried out analyzing and processing by digital processing circuit, draw the distance value of preceding object thing, 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, master control system regulates the gear of retarder automatically according to the size of the distance value received.
Described digital processing circuit is also connected with selecting arrangement, can select other several functions, as warning function.
Described digital processing circuit is also 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, slow gear is adjusted according to the distance of front vehicles, chaufeur alleviates shock dynamics when having little time startup retarder and front vehicles collides, avoid especially big traffic accident occurs, improve deceleration and stopping performance.
