Plane embedded type car-backing radar system, car-backing control system and control method

Abstract

The invention discloses a plane embedded type car-backing radar system which comprises car-backing radar and a car-backing radar control module. The car-backing radar is plane embedded type radar, a probe core of the car-backing radar is kept flush with a rear protective face, the car-backing radar and the car-backing radar control module are directly connected through a nose cabin wiring harness, and according to the distance between a car and a barrier, different pattern display and sound alarms in different zones are achieved by the car-backing radar control module. The invention further discloses a control method for car-backing warning through the plane embedded type car-backing radar system and the car-backing control system comprising the plane embedded type car-backing radar system. The plane embedded type car-backing radar system is compact in structure, stable and reliable in performance, capable of achieving port level type change, small in current and EMI, capable of achieving EMC correlation indexes easily, standard in port protocol type communication, flexible in change and capable of achieving application modularization easily.

Description

technical field [0001] The invention belongs to the field of automobile electronic control, in particular to a plane embedded reversing radar system and its control method, which has the auxiliary function of controlling parking by using the reversing radar and the reversing radar module. Background technique [0002] With the continuous development and progress of automobile technology, people's demand for intelligent control of automobiles is getting higher and higher. At present, most of the reversing radar systems equipped with vehicles are composed of reversing radars and reversing radar modules. The system is controlled by external interference. , It is far from meeting people's demand for intelligent control of automobiles. Due to its own characteristics, the existing reversing radar has high requirements on the layout space, and if it is arranged close to the spare tire or the license plate frame, it is easy to generate false alarms. [0003] In the existing analog ...

Problems solved by technology

[0003] In the existing analog radar system, the analog radar transmits and receives signals without much signal processing. Such weak signals are transmitted to the ECU for processing through a certain length of wire. Interference and loss on the line, although using shielded wires to transmit can improve the effect to a certain extent, but the cost increases, and the improvement effect is quite limited. The small interference introduced during the transmission process will reduce the signal-to-noise ratio of the input signal, resulting in The detection sensitivity of the system is unstable, and this solution has poor anti-interference and product interchangeability
