Large transport vehicle safety protection system and early warning method

Abstract

The invention relates to a large transport vehicle safety protection system and an early warning method. The early warning method comprises the steps that S1, the system conducts power-on self-test; S2, a millimeter wave radar assembly transmits obstacle target information detected in real time to a system processing terminal, and a camera assembly transmits road image information recorded in realtime to the system processing terminal; S3, the system processing terminal gives a radar confidence factor and a camera confidence factor to each target in real time; S4, the total confidence of eachtarget is calculated in real time, and whether the target is a real target or not is judged in real time according to the total confidence; and S5, according to the current vehicle speed and the realtarget, early warning is carried out on a right ahead target during starting, or a right ahead target during driving, or a side target during steering, or a side target during lane changing, or a rear target during lane changing. According to the invention, radar, camera and vehicle driving parameter information are combined, the detection range is expanded, and the method is used for vehicle front dead zone detection, lateral anti-collision and rear dead zone detection.

Description

technical field [0001] The invention relates to a safety protection system of a large transport vehicle and an early warning method thereof, in particular to a target detection technology for a driver's visual blind spot. Background technique [0002] With the development of ADAS (Advanced Driving Assistant System, Advanced Driving Assistant System) technology and the improvement of vehicle information technology, vehicle safety protection methods have changed from passive display and notification of rearview mirrors and turn signals to The development of active detection technology relying on ultrasonic probes, radars, cameras, etc. [0003] Although related technologies have been popularized and developed in passenger vehicles first, when large vehicles collide with small vehicles or run over pedestrians or non-motorized vehicles, they often have more adverse social impacts and serious consequences. Economic losses, so the demand for related technologies is more urgent an...

Problems solved by technology

This patent uses a combination of pure vision sensors, which of course will be affected by adverse weather conditions such as rain and dust.

[0008] In addition, there are relatively few studies and elaborations related to specific alarm strategies in the prior art

Today, with the rapid development of sensor technology, the detection of dangerous targets is no longer the main technical bottleneck, but it is more in line with the driving habits of human drivers, actively filtering out detected but non-dangerous targets, so that they will not be detected when the driver is driving normally. It will cause false alarms and will not affect the driver's driving experience. At present, even the safety protection systems on quite a lot of mass-produced small cars are still insufficient.
