Description
Technical field
The present invention relates to sensor technical fields, and in particular to a kind of radar arrangement.
Background technique
We often can be appreciated that the news in relation to traffic accident, and these accident majorities are related with truck, so that
In truck at " the road killer " in many human eyes.And the accident of truck is most all related with " vision dead zone ", because
Generally all long (> 6m) for medium-and-large-sized passenger-cargo carriage vehicle body, domestic biggish 12 meters of public transport bus at present, lorry is according to suitable
It is various, different in size with range and function classification, it is longest to have 17 meters.Since medium-and-large-sized passenger-cargo carriage length of wagon is long, drive
For the person of sailing when driving vehicle carries out turn or lane change, there are a blind area, drivers to be hardly visible side indoors for vehicle body side
Vehicle situation is carried out in face blind area, can not make accurate judgement, is easy for that traffic accident occurs.
For this phenomenon, it is mainly the following precautionary measures on the market: the monitoring of video blind area, ultrasonic blind zone monitoring
Deng.The monitoring of video blind area is to acquire video data by installing camera in left and right vehicle wheel rearview mirror position, realizes vehicle
Blind area monitoring.But this monitoring system mounting means is not only unsightly, but also vehicle in rain and snow or night when driving,
Monitoring system will receive the influence of weather conditions, quality monitoring decline, and driver can not be clearly seen that blind area in driver's cabin
Scene, then the probability of traffic accident, which occurs, to be greatly improved.Ultrasonic blind zone monitoring is by vehicle tail left and right sides
Mounting ultrasonic sensor shows blind area scene in left and right vehicle wheel rearview mirror installation display screen, and this monitoring system installation is not
The monitoring of blind area can be completely covered, and this mounting means is only applicable to kart, be mounted on medium-and-large-sized passenger-cargo carriage, drive
The person of sailing still has security risk when driving.
And radar sensor is installed on automobile, it realizes the functions such as anticollision, automatic parking, the pedestrian detection of automobile, is me
In automobile auxiliary intelligent driving system the Yi Tiaolu that gradually comes out of, this, which represents, following realizes that unpiloted one kind becomes
Gesture.But due to the car radar of current mainstream --- 24GHz radar is limited to frequency range control, radio astronomy 5Km does not allow the wave
Duan Leida is used and the reasons such as own vol big (mainly antenna volume is big), and gradually commercialization and equips
The distribution frequency range of high-end automobile is wider, and distance resolution is higher, and volume is relatively small, the strong 77GHz of target acquisition ability, 79
GHz car radar, can be can under round-the-clock scene quick sensing 0-200 meters of range inner periphery environmental objects distance,
The senser element of the information such as speed, azimuth, therefore in automatic driving security fields, Automobile Millimeter Wave Radar sensor is
Through becoming one of core component, wherein 77GHz, 79 GHz millimetre-wave radars are essential critical components on intelligent automobile.
But since its volume is more than 32mm's for not allowing to install in medium-and-large-sized passenger-cargo carriage, the especially side body of large size passenger-cargo carriage
Component largely defines the application of 7GHz, 79 GHz car radars on medium-and-large-sized passenger-cargo carriage.

It is the installation limitation on the side vehicle body of large-scale passenger-cargo carriage.Millimetre-wave radar launches outward millimeter wave by antenna, and it is anti-to receive target
Signal is penetrated, physical context information (such as automobile and other objects around body of a motor car are rapidly and accurately obtained after rear is handled
Between relative distance, relative velocity, angle, the direction of motion etc.), target tracking is then carried out according to the object information found out
Classify with identification, and then vehicle body multidate information is combined to carry out data fusion, carries out intelligence eventually by central processing unit (MCU)
Processing.After Rational Decision, is informed with various ways such as sound, light and tactiles or alert driver, or master is made to automobile in time
It is dynamic to intervene, to guarantee safety and the comfort of driving procedure, reduce accident occurrence probability.The frequency of preferred wireless electromagnetic wave
The millimeter-wave automotive radar of 79Ghz is monitored for blind area.Efficiently use millimetre-wave radar various features (have penetrating fog, cigarette,
The ability of dust is strong, has the characteristics of round-the-clock, round-the-clock can all work normally, and by multiple waterproof structure, makes millimeter
The service life of wave radar is longer, and price is low, can reduce cost；The target of identification very little can be differentiated, and can identified simultaneously more
A target, therefore there is very strong spatial discrimination and imaging capability；System sensitivity is high, and mistake rate of false alarm is low, not vulnerable to the external world
The interference of electromagnetic noise；With higher tranmitting frequency, lower transmission power；The distance and speed of multiple targets can be measured simultaneously
Degree, and target can be continuously tracked, or even tracking can also be kept not lose to static target；It is high apart from remote real-time) it can
The monitoring of the side view blind area of medium-and-large-sized, particularly large-scale passenger-cargo carriage is preferably served, monitoring effect is promoted.
