Integrated FCW/ACC/AEB system based on prediction model and vehicle

Abstract

The invention provides an integrated FCW / ACC / AEB system based on a prediction model and a vehicle, and belongs to the field of vehicle control. The integrated system comprises an environment perception fusion device, an operation decision control device connected with the environment perception fusion device, and an execution device connected with the operation decision control device. By fusing data acquired by a visual sensor with data acquired by a radar sensor, the perception of the whole system to the environment is improved, and acquired vehicle condition and road condition information is more complete and accurate; through switching of various working modes, the adaptability of the system to complex traffic conditions is improved, and diverse driving needs of drivers are met; the adaptability of an adaptive cruise system to roads is improved, the driving labor intensity of drivers is relieved, the safety of vehicle driving is improved, the personal safety of drivers is ensured,and traffic accidents are avoided or alleviated.

Description

technical field [0001] The invention belongs to the field of vehicle control, in particular to an integrated FCW / ACC / AEB system and a vehicle based on a predictive model. Background technique [0002] In recent years, with the rapid development of the automobile industry, the number of automobiles has also increased rapidly. Although automobiles have provided great convenience for human production and life, they have also brought various problems such as road congestion, various traffic accidents, energy waste, and environmental pollution. Therefore, improving the safety performance and energy utilization rate of automobiles and reducing the incidence of traffic accidents is a very important issue, and it is also a problem that intelligent transportation systems need to work hard to solve. [0003] At present, intelligent driving assistance systems include adaptive cruise control (Adaptive Cruise Control, ACC), automatic emergency braking system (Autonomous Emergency Brakin...

AI Technical Summary

Problems solved by technology

There are still some deficiencies in the ACC system: For example, the adaptability to the environment is poor. Generally, when driving on a straight road, the system can make correct judgments and analyzes in real time according to the road conditions, but in most curved road conditions, it often makes wrong decisions and judgments. , such as the radar sensor will misjudge the vehicle in the adjacent lane as the target object in the lane after entering the curve, or lose the tracked target object before leaving the curve, which will bring danger to the driver and affect driving safety; for example, When the vehicle suddenly inserts (when the distance from the vehicle is close to the critical point of the safe braking distance), the switching between adaptive cruise, front collision avoidance warning and automatic emergency braking is not sensitive, and the vehicle cannot be quickly braked in a dangerous moment. For example, the working mode switching mode of the ACC system is relatively simple, and generally only has the functions of constant speed cruise, fixed distance cruise, and Stop&Go, which cannot meet the driver's more needs for the ACC system and cannot well adapt to the existing complex traffic conditions
