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.

    本发明涉及一种车辆换道时的车速辅助控制方法、系统及汽车,以实现对车辆换道时的车速辅助控制,实现车辆的快速换道和安全换道。该一种车辆换道时的车速辅助控制方法,包括:针对配置有巡航驾驶功能且开启巡航驾驶功能的车辆,判断车辆是否满足激活换道车速辅助控制功能的条件;若满足,判断车辆当前所处环境是否满足换道的条件;若满足,则对车辆和可能在本车换道时与本车发生碰撞的运动目标进行态势评估,以确定车辆是否满足进入车速辅助控制的条件;若满足,则按照本车和轨迹前方的第一运动目标之间的相对运动参数,对本车进行辅助车速控制。
