The invention provides an intelligent speed limiting method and device for a vehicle, which are used for performing speed limiting control in a process of surpassing a low-speed traffic flow of an adjacent lane by identifying the states of the vehicle and the adjacent lane vehicle. Comprising the following steps: S1, monitoring the motion state of a vehicle and the motion states of vehicles on a lane and an adjacent lane; s2, determining to start overtaking according to the monitoring data; s3, in the overtaking process, the traffic flow state is judged; s4, when it is determined that the vehicle is passing through the low-speed traffic flow, according to the threshold interval where the vehicle speed difference between the vehicle and the vehicle on the adjacent lane is located, different speed limiting control is conducted on the vehicle, and the speed limiting control comprises traffic-flow-free speed reduction, oil-receiving speed reduction and braking speed reduction to the target vehicle speed; and S5, overtaking is completed, and the target vehicle speed before speed limiting is recovered. The method can effectively prevent the driver and passengers from feeling oppressed due to vehicle speed difference and overlong and overlarge traffic flow, improves the driving experience, and guarantees the safe driving of the vehicle.

    本发明提供一种车辆智能限速方法及装置,是通过识别本车及邻道车辆状态,在超越邻道慢速车流过程进行限速控制。包括:S1,监测本车运动状态、本车道及邻道车辆的运动状态;S2,根据监测数据,确定开始超车;S3,在超车过程中,判断车流状态;S4,在确定正经过慢速车流时,根据本车与邻道车的车速差所在的阈值区间,对本车进行不同的限速控制,包括无车流不减速、收油减速和制动减速至目标车速;S5,完成超车,恢复限速前目标车速。本发明可以有效防止因车速差、车流过长过大导致驾驶员及乘坐人员压迫感,提升驾乘体验,保障车辆安全行驶。
