A system and method for vehicle cruise

Abstract

The invention discloses a vehicle cruising system and a vehicle cruising method, which relate to the field of vehicle safety. The invention provides a vehicle cruising system and method, Multi-sensorsare used to perceive the environment, and the information of different sensors is recharacterized in order to realize high-level nonlinear data fusion, and local 3D map is constructed to assist decision-making, which can improve the depth perception of the driving environment and achieve good self-adaptation and decision-making. In addition, the invention can identify the obstacle type, can makemore effective decision feedback for the obstacle with higher danger degree, and improves the real-time decision performance and flexibility of the vehicle cruising system. The vehicle cruising systemand the vehicle cruising method provided by the invention have strong comprehensive perception ability to the obstacles around the vehicle, strong strain flexibility to the obstacles, and diversifiedanti-collision technical functions, and are very suitable for complex and changeable road conditions.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a vehicle cruise system and method. Background technique [0002] With the rapid development of the domestic automobile industry and the increase in automobile production and sales year by year, the traffic pressure is increasing day by day, and the road transportation safety situation is becoming increasingly severe. According to the "Statistical Bulletin of National Economic and Social Development of the People's Republic of China in 2016", the number of deaths per 10,000 vehicles in road traffic accidents in my country is 2.1. The frequent occurrence of severe and vicious traffic accidents not only seriously endangers the safety of people's lives and properties, but also easily causes complex social problems. Therefore, active safety technology, as an important means to solve traffic problems, has been highly valued by governments of all countries and has become a medium- and lon...

Problems solved by technology

[0006] Most of the intelligent cruise systems in the related art detect the speed and distance of obstacles in front of the vehicle through radar, but cannot effectively identify the type of obstacles, and the intelligent cruise system cannot perceive and obtain environmental data on the sides and rear of the vehicle Therefore, the intelligent cruise system has a low comprehensive perception ability to obstacles around the vehicle, poor response flexibility to obstacles, and a single anti-collision technology function.
