The utility model can carry out real-time display to the relative speed of obstacles in front of a vehicle, and can simultaneously carry out intelligent anticollision treatment according to predetermined programs. The utility model can respectively output speech prompt signals, automatic deceleration signals and brake signals according to different early warning situations, and can make the vehicle decelerated or braked automatically through the deceleration and brake executing system 6.
Description
The utility model is a kind of self-propelled vehicle intelligent anticollision radar installation, belongs to self-propelled vehicle safety protection technique field.
In the prior art, as disclosing a kind of new motor vehicle electronic anticollision device in the Chinese patent " 01218153.6 " " motor vehicle electronic anticollision device ", it installs transmitting probe at front part of vehicle, when in probe is sensed the place ahead safety distance, obstacle being arranged, send the signal cut ignition circuit by electronics package, make vehicle flame-out, drive brake actuator simultaneously and brake, avoid bumping against.Weak point is the relative velocity that can't show the place ahead obstacle, lacks intelligent anticollision and handles and sound prompt function, for the self-propelled vehicle in travelling, does not have warning effect in advance, only play the self-actuating brake effect, thereby the safety precaution effect is undesirable.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of relative velocity that can show the place ahead obstacle in real time, and has an intelligent anticollision processing capacity, can carry out the self-propelled vehicle intelligent anticollision radar installation of voice suggestion, automatic deceleration and brake respectively according to different early warning situations.
The purpose of this utility model can reach by following measure: a kind of self-propelled vehicle intelligent anticollision radar installation, form by microwave emitting and receiving head 1, signal processing circuit 2, single chip circuit 3, digital display circuit 4, voice playing circuit 5 and deceleration and brake actuating system 6, it is characterized in that ic chip
