Vehicle control method

Abstract

The invention provides a vehicle control method. The method comprises the steps that when an automatic braking function is triggered and potential lane changing allowing a vehicle to change lanes does not exist in adjacent lanes, the vehicle is controlled; the vehicle is controlled to decelerate until the speed is zero, the distance between the vehicle and a front object is larger than or equal to the safe lane changing distance d after the speed of the vehicle is zero, and the front object comprises a front obstacle and / or a front vehicle; and after the speed of the vehicle is reduced to zero, if it is judged that potential lane changing allowing the vehicle to change lanes exists in the adjacent lanes, the vehicle is controlled to execute lane changing. The technical problem that in the prior art, emergency braking and automatic lane changing schemes mostly adopt the mode of direct lane changing in combination with the V2X technology in the movement process, and how to change lanes after automatic braking under the condition that the road condition does not meet the lane changing requirement during automatic braking is not considered is solved.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a vehicle control method. Background technique [0002] Serial rear-end collision accidents often occur on expressways, which not only pose a safety threat to drivers and passengers, but also cause traffic jams. [0003] At present, self-driving vehicles are usually equipped with an AEB (Autonomous Emergency Braking) automatic braking system, but most of the emergency braking and automatic lane change solutions in the prior art use the method of directly changing lanes in combination with V2X technology during the movement process, without considering automatic braking. When the road conditions do not meet the lane change requirements, how to change lanes after automatic braking. For example, when AEB braking, only consider that the vehicle in front does not collide with the vehicle in front, but does not consider the collision between the vehicle in front and the vehicle in front after b...
