The invention discloses a vehicle self-adaptive cruise control method and device. The method comprises : obtaining a speed before speed changing, a speed after speed changing and a speed changing distance of a vehicle at each speed changing position; calculating a variable speed of each speed change position according to the speed before speed change, the speed after speed change and the speed change distance; calculating a first numerical value according to the variable speed and the variable speed distance; according to the corresponding relation between the first numerical value and the vehicle following time interval, determining a vehicle following time interval of the vehicle at each speed changing position, and determining the vehicle following time interval corresponding to the maximum first numerical value as the vehicle following time interval of the vehicle; and adjusting the driving speed by using the following time interval of the vehicle. According to the invention, vehicle following time intervals of a vehicle at different speed changing positions are obtained, the vehicle following time interval corresponding to the first numerical value at the maximum speed changeposition is determined as the current vehicle following time interval of the vehicle, the influence of the vehicle machine performance change on the vehicle following effect is considered in the determination of the vehicle following time interval, and the vehicle driving speed is adjusted according to the current vehicle following time interval, so that the driving safety and the driving experience of a user are improved.

    本发明公开了一种车辆自适应巡航控制方法及装置。方法包括:获取车辆在各变速位置的变速前车速、变速后车速和变速距离;根据变速前车速、变速后车速和变速距离计算各变速位置的变速度;根据变速度和变速距离计算第一数值;根据第一数值与跟车时距的对应关系确定车辆在各变速位置的跟车时距,将最多第一数值对应的跟车时距确定为车辆的跟车时距;利用车辆的跟车时距调整行驶速度。本发明获取车辆在不同变速位置的跟车时距,将最多变速位置上的第一数值对应的跟车时距确定为车辆当前的跟车时距,在跟车时距的确定上,考虑到的车辆车机性能变化对跟车效果的影响,根据当前的跟车时距调整车辆行驶速度,提高了用户驾驶的安全性和驾驶体验。
