A reversing lateral assistance system and its data fusion and control method

Abstract

The invention discloses a rear cross traffic alert system. The rear cross traffic alert system comprises a detection module and a control module which are connected with each other. The detection module is used for detecting environment information data and transmitting the environment information data to the control module and comprises a first detection device used for detecting target information in the environment behind the side of a vehicle and a second detection device used for detecting target relative information in the environment behind the side of the vehicle. The control module isused for receiving the environment information data detected by the detection module, conducting data fusion processing in combination with vehicle sensor signals and conducting control according toprocessed information. By the adoption of the system, the target information is detected through the first detection device, the target relative information is detected through the second detection device, a recognized environment system database is greatly enriched, computation of a controller is convenient, the sensing capacity of the rear cross traffic alert system to the true environment is enhanced, and the robustness is good.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to a reversing lateral assistance system and a data fusion and control method thereof. Background technique [0002] In recent years, with the increase of car ownership, the incidence of traffic accidents has also increased day by day. Therefore, Rear Cross Traffic Alert (RCTA) is becoming more and more important, and the research and development of Rear Cross Traffic Alert (RCTA) has gradually attracted people's attention. [0003] The reverse side assist system uses sensors to detect target objects behind the main vehicle. The system recognizes and tracks target objects (vehicles, bicycles, pedestrians) entering the alarm area. If there is a risk of collision with the target object, the potential Hazard warning to the driver, even brake the vehicle. [0004] Currently on the market, the Reversing Side Assist System (RCTA) is mainly based on the environment perception recognition...

AI Technical Summary

Problems solved by technology

[0006] Since the current reverse lateral assist system (RCTA) is only a single sensor recognition mode, it can only provide part of the information of the environment, so there are some defects for some special working conditions

For example, when the vehicle is reversing, there may be small moving obstacles (such as people and pets) escaping from the rear, which may not be detected by the radar, and the alarm and braking cannot be timely; therefore, the automatic driving solution of a single sensor recognition mode cannot be avoided in essence. The risk of the above working conditions, which in turn affects the convenience and comfort of the driver
