The invention discloses an auxiliary driving method and a vehicle. The method comprises the steps that a sensor detects the instant geographic position of the vehicle and the driving speed of the vehicle; and determining environment information of the vehicle according to the real-time geographic position of the vehicle and the high-precision map. The environment information comprises a driving lane of the vehicle, a target lane, the width of the driving lane and the width of the target lane. When the sensor detects that another vehicle exists in the target lane, the absolute speed of the another vehicle and the relative speed between the vehicle and the another vehicle are calculated. And when the value of the absolute speed is smaller than the first preset value and the value of the relative speed is smaller than the second preset value, it is recognized that the vehicle has a blind area in the target lane, an auxiliary driving instruction is generated, the blind area of the vehicle can be pre-judged, the vehicle driving safety is improved, and vehicle intelligent control is optimized.
一种辅助驾驶方法及车辆,该方法包括:传感器检测车辆的即时地理位置及车辆的行驶速度;根据车辆的即时地理位置及高精地图确定车辆的环境信息。环境信息包括车辆的行驶车道、目标车道、行驶车道的宽度及目标车道的宽度。在传感器检测到目标车道内存在另一车辆时,计算另一车辆的绝对速度及车辆与另一车辆之间的相对速度。在绝对速度的数值小于第一预设值且相对速度的数值小于第二预设值时,则识别车辆在目标车道内存在盲区并产生辅助驾驶指令,可对车辆的盲区进行预判,提高车辆驾驶的安全性,优化车辆智能控制。
