Abstract

The invention provides a vehicle anti-collision pre-judging method and device, equipment and a readable storage medium. The method comprises the following steps of acquiring current road scene information of a vehicle; determining a pre-judging time according to the current road scene information; determining an anti-collision strategy according to the pre-judging time; and controlling the vehicleto run according to the anti-collision strategy. According to the method,the vehicle can pre-judge occurrence of an obstacle associated with an obstacle in the current road scene according to the current road scene information, an avoidance collision decision is made in advance, so that the vehicle has enough reaction time and reaction capacity to avoid the occurrence of traffic accidents, and the intelligent level of the automatic driving vehicle is further improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of unmanned driving, and in particular to a vehicle anti-collision prediction method, device, equipment and readable storage medium. Background technique [0002] With the development of computer technology and artificial intelligence, unmanned vehicles (referred to as: unmanned vehicles) have broad application prospects in transportation, military, logistics and warehousing, and daily life. Unmanned driving technology mainly includes the perception of environmental information, intelligent decision-making of driving behavior, planning of collision-free paths, and vehicle motion control. [0003] Existing unmanned vehicles only pay attention to the perceived obstacles in the current environment when sensing environmental information. If the relative distance between the unmanned vehicle and the obstacle is less than the predicted collision distance, the unmanned vehicle immediatel...
