Embodiment approach

[0107] Suppose the vehicle in front is A C Do uniform deceleration exercise. Based on the above information, use the lane change method in the patent application number 201510381349.9 to formulate a plan, and if feasible, execute the lane change operation. If the conditions for changing lanes are not met or there is an unexpected situation when changing lanes, the parking scheme will be used for emergency avoidance. The specific calculation method is as follows:

[0108]Based on the above conditions, the total braking distance S of the vehicle in front can be obtained C and braking time T C :

[0109]

[0110]

[0111] According to the above conditions, it can be assumed that the vehicle in front is located in front of the vehicle L 1 (L 1 =L'+S C ) for static obstacles at ), the scheme calculation refers to Figure 3A The method shown was developed.

[0112] From the above scheme planning and calculation process, it can be seen that there is a dynamic obstacle d...

Abstract

The invention provides an emergency avoidance system and method for an unmanned automobile. An environment detection system of the unmanned automobile is used for sensing the surroundings, and the conditions such as the types and the states of avoiding objects are distinguished; according to the actual condition of the avoiding objects, analysis and decisions are made, and an emergency avoidance scheme is acquired; then, decision information is sent to a vehicle control device so that the avoidance action can be executed; and finally, according to real-time information, whether avoidance is successful or not and whether the scheme needs to be planned again or not are judged. By the adoption of the emergency avoidance system, measures are taken actively before an accident occurs to the automobile, and the occurrence rate of accidents of the automobile can be effectively reduced.

Description

[0001] Cross References to Related Applications [0002] The planning method of the lane change scheme in this application relates to the patent application with the application number 201510381349.9 and the title of the invention "An autonomous lane change decision system for unmanned vehicles" submitted on July 3, 2015. The entire content of this application is hereby incorporated by reference. technical field [0003] The invention belongs to the technical field of intelligent transportation, and in particular relates to an emergency avoidance system and a planning calculation method for an unmanned vehicle. Background technique [0004] With the development of urbanization and the popularization of automobiles, traffic accidents caused by speeding, road occupation, fatigue driving, drunk driving, and untimely avoidance are becoming more and more serious. The emergence of unmanned vehicles provides the possibility to improve vehicle driving safety and reduce traffic acci...
