The invention provides a vehicle speed adjusting method and device applied to a vehicle. The vehicle speed adjusting method comprises the steps that the preset vehicle speed of the vehicle is obtained; acquiring a preset speed and a real-time position of the vehicle; obtaining a corresponding detection distance according to the obtained preset vehicle speed; obtaining the road condition in the corresponding detection distance range according to the real-time position; and adjusting the preset speed of the vehicle according to the obtained road condition in the corresponding detection distance range. The road congestion conditions in different distance ranges are detected according to the preset vehicle speed, and whether the preset vehicle speed is adjusted or kept is judged according to the congestion conditions, so that the vehicle speed of the vehicle can be always kept in a safe range. Therefore, when an emergency occurs in the forward direction of the vehicle, the vehicle can be quickly braked from a higher vehicle speed in time, so that the situation that the vehicle needs to be braked emergently, and bad experience is brought to a driver or passengers is avoided.
本发明提出一种应用于车辆的车速调整方法及装置,所述车速调整方法包括:获取本车的预设车速;获取车辆的预设车速及实时位置;根据获取的预设车速得到一对应的侦测距离;根据实时位置获取对应的侦测距离范围内的道路状况;及根据获取的对应的侦测距离范围内的道路状况,调整车辆的预设车速。根据预设车速的大小决定侦测不同距离范围内的道路拥堵状况,并依据拥堵状况判断是否调整或保持预设车速,从而能够确保车辆的车速始终保持在安全的范围内。如此,在车辆前行方向出现紧急情况时,车辆能够及时从一个较高的车速快速制动,从而避免车辆需要紧急制动,给驾驶员或乘车人员带来不好的体验。
