The invention relates to an auxiliary driving method and device based on a congested road condition, and the method comprises the steps: obtaining the vehicle speed of a target vehicle at the current moment and the vehicle speed change trend of the target vehicle in a preset period, and enabling the termination moment of the preset period to be the current moment; under the condition that the vehicle speed meets the preset condition, the target vehicle is controlled to enter a traffic jam auxiliary function mode, and lane line information of a road section where the target vehicle is located is collected; determining a processing strategy by using the vehicle speed and the vehicle speed change trend, and processing the lane line information according to the processing strategy to obtain a processing result; and acquiring a control target matched with the processing result, and performing transverse control based on the control target. Whether the lane line information needs to be updated is determined according to the vehicle speed and the vehicle speed change trend. And the driving safety and stability can be conveniently improved. In addition, the control target is selected according to the processing result of the lane line information, so that the target vehicle can better adapt to the current road condition and the lane condition. And the comfort and the stability of driving are improved.
本发明涉及一种基于拥堵路况的辅助驾驶方法及装置,包括:获取目标车辆当前时刻的车速以及目标车辆在预设周期内的车速变化趋势,预设周期的终止时刻为当前时刻;在车速满足预设条件的情况下,控制目标车辆进入交通拥堵辅助功能模式,并采集目标车辆所处路段的车道线信息;利用车速以及车速变化趋势确定处理策略,并按照处理策略对车道线信息进行处理得到处理结果;获取与处理结果相匹配的控制目标,并基于控制目标进行横向控制。本申请利用车速和车速变化趋势确定是否需要更新车道线信息。便于提高行车的安全性和稳定性。另外根据车道线信息的处理结果选择控制目标,可以使目标车辆更好地适应当前路况和车道情况。提高了驾驶的舒适度和稳定性。
