Multifunctional automobile millimeter wave radar early warning system

Abstract

The invention provides a multifunctional automobile millimeter-wave radar early warning system. The multifunctional automobile millimeter-wave radar early warning system comprises an ultra-wide horizontal field angle antenna, a millimeter-wave radar transceiving module, a control assembly communication module, a driving position early warning module, a vehicle information collection module, a leftreflector early warning module and a right reflector early warning module. The system is advantaged in that five blind area monitoring functions of blind area monitoring, lane changing assistance, door opening early warning, rear traffic passing early warning and backward collision early warning under a single radar condition can be realized by only depending on one set of automobile radar receiving and transmitting system, the system has a near-field mode and a far-field mode, and completely different target detection, aggregation, tracking, alarm and other functions are carried out on a long-distance target and a short-distance target in algorithm processing; a radar transceiving antenna is designed to be a wide wave beam on a horizontal plane, the radar detection area is effectively increased, complexity of the automobile blind area monitoring radar system is effectively reduced, and the vehicle-mounted millimeter wave radar system is simpler and more convenient to install and use.

Description

technical field [0001] The invention relates to the technical field of automobile automation control, in particular to a multifunctional automobile millimeter wave radar early warning system. Background technique [0002] With the progress of the society, the demand of the automobile market continues to increase, and people have higher and higher requirements for the overall performance of the vehicle, and they are increasingly pursuing speed, convenience and intelligence. Today's automotive electronics technology field is changing with each passing day, and more electronic products have become more and more humanized to meet people's pursuit of comfort, safety, intelligence and other factors. The blind spot monitoring radar can help the driver to monitor the blind spot position at the rear of the car from time to time during the driving process. Once the blind spot risk occurs, the blind spot monitoring car radar system can promptly remind the driver or force the car to per...
