Intelligent reversing parking radar

Abstract

The invention belongs to an auxiliary device for assisting in a backing and parking vehicle, in particular to an intelligent backing and parking radar. The intelligent backing and parking radar comprises radar probes arranged on the vehicle tail or on both sides of the vehicle tail, a microprocessor module, an acousto or optical alarm module and a steering state information data interface, wherein the radar probes, the acousto or optical alarm module, the steering state information data interface and the microprocessor module are connected with each other; and the microprocessor module real-timely adjusts the level of acousto or optical alarm signals correspondingly triggered by signal of each radar probe according to the steering state information read from the steering state data interface. The invention can maximally obviate false alarm of parking radars while steering and parking a vehicle and can also help drivers reasonably adjust the steering state to an optimal running trajectory in time.

Description

technical field [0001] The invention belongs to a motor vehicle reverse parking auxiliary device, and more specifically relates to an intelligent reverse parking radar system. Background technique [0002] With the continuous improvement of the level of science and technology and the development of driving assistance technology, the method of installing radar probes at the rear or both sides of the vehicle body to detect obstacles has been widely used and popularized, which is called reversing radar or parking radar (hereinafter referred to as reversing radar) Radar), radar probes include ultrasonic probes and optical probes. Generally, the strength of the output signal reflects the distance between the probe and the obstacle; The image warning signal is reflected to the driver. Most of the existing reversing radar systems set a fixed corresponding alarm signal strength level for the signal strength of the radar probe at the rear of the vehicle. [0003] However, most driv...

Problems solved by technology

[0003] However, most drivers will have a certain steering angle to drive the vehicle on a curve when reversing or parking, that is to say, the rear of the car is still changing direction while moving backwards. The signal strength of the probe is set to a fixed corresponding alarm signal strength level, so in many cases, obstacles that are not on the rear of the vehicle will cause false alarms because they are directly behind the rear of the vehicle, and cannot provide the driver with correct obstacle position information. Affects reversing safety to a great extent
