Embodiment Construction
[0032] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.
[0033] In a preferred embodiment, the following scheme can be adopted: emergency braking control decision-making strategy design is the core of automatic emergency braking. Traditional emergency braking adopts the method of supervised learning, that is, artificially setting the corresponding relationship between the driving speed of the smart car and the emergency braking distance. For example, when the defined speed is 60km / h, the safe braking distance of the smart car is 50 meters, and the defined speed is 40km / h, the safe braking distance of the smart car is 30 meters, etc. In the actual driving process, the smart car searches for an artificially defined corresponding distance according to the speed of the smart car, and then realizes emergency braking. The flexibility, maneuverabil...

The invention relates to an emergency braking control system and a control method thereof. The emergency braking control system comprises a first neural network module and a second neural network module, wherein the first neural network module is a motion behavior decision making module and is connected with a vehicle physical system and used for providing a behavior decision for the system according to the state quantity of a dynamic system; and the second neural network module is a motion decision evaluation module and is connected with the motion behavior decision making module and used for evaluating the decision motion made by the motion behavior decision making module according to an enhanced signal provided by the dynamic system. According to the emergency braking control system and the control method thereof, the purpose of emergency braking of intelligent vehicles is achieved through a heuristic dynamic planning algorithm, the intelligent vehicles are made to learn the corresponding relation between the speeds and the braking distances automatically through the feedback regulation of neural networks, and accordingly the stability, reliability and adaptivity of emergency braking are made better.
Description
technical field [0001] The invention relates to automobile active safety, in particular to a design method for an emergency braking control system of an intelligent vehicle based on a heuristic dynamic programming algorithm. Background technique [0002] For more than a century, the emergence of automobiles has replaced traditional transportation methods, making people's lives more convenient. But in recent years, car safety issues have received more and more attention. According to the survey, in 2011, the number of traffic accident deaths in the top six countries with car ownership in the world were: the United States, 32,310 people, China, 62,000 people, Japan, 4,612 people, Germany, 4,009 people, Italy, 3,800 people, and Russia, 27,900 people. In 2012, there were 204,196 traffic accidents in China, 59,997 people were killed, 224,327 people were injured, and the direct property loss was 1,174,896,000 yuan. [0003] From the above data, it can be seen that a. The number ...
