Abstract

The invention relates to an auxiliary vehicle speed control method and system during lane changing of a vehicle and a vehicle, thereby realizing auxiliary vehicle speed control during lane changing ofthe vehicle and realizing rapid lane changing and safe lane changing of the vehicle. The auxiliary vehicle speed control method comprises the steps that: whether a vehicle that is provided with a cruise control function and enables the cruise control function to be activated meets a condition of activating the auxiliary lane changing vehicle speed control function or not is determined; if so, whether the current environment meets the lane changing condition or not is judged; if so, situation evaluation is conducted on the vehicle and a moving target possibly colliding with the vehicle duringlane changing of the vehicle so as to determine whether the vehicle meets the condition of entering auxiliary vehicle speed control or not; and if so, auxiliary vehicle speed control is conducted on the vehicle according to relative motion parameters between the vehicle and a first moving target in front of the track.

Description

technical field [0001] The invention relates to the field of vehicle speed control, in particular to a vehicle speed auxiliary control method, system and vehicle when changing lanes. Background technique [0002] In the process of driving, changing lanes and overtaking is a common driving behavior. Most drivers start to accelerate and overtake after turning on the turn signals, lacking judgment on the surrounding traffic conditions, posing safety risks and affecting driving comfort. [0003] At present, in the field of intelligent driving, the longitudinal distance between vehicles is controlled according to the set time distance. When the ego vehicle is approaching the vehicle in front quickly, the ego vehicle will decelerate prematurely, and the driver will usually change lanes when approaching the vehicle in front. The cruise control system will control the speed of the vehicle to not exceed the speed of the vehicle in front, and the driver will often choose to accelera...
