The invention discloses a vehicle override control method and system based on an override mode, and the method comprises the steps: 1, obtaining a current vehicle distance D between a vehicle and a front vehicle in the override mode; and 2, judging the current vehicle distance D, a vehicle distance threshold value D1 and a vehicle distance threshold value D2, the vehicle distance threshold value D1 is the safety vehicle distance during vehicle self-adaptive cruise, the vehicle distance threshold value D1 is larger than the vehicle distance threshold value D2, and when the current vehicle distance D is larger than or equal to the vehicle distance threshold value D1, reminding a driver of performing acceleration overtaking according to the acceleration required speed; and when the current vehicle distance D is larger than or equal to the vehicle distance threshold D2 and smaller than the vehicle distance threshold D1, reminding the driver of performing acceleration overtaking according to 40%-60% of the acceleration required speed, and when the current vehicle distance D is smaller than the vehicle distance threshold D2, controlling the vehicle to be kept at the current speed for self-adaptive cruise. According to the method, whether the vehicle can overtake can be determined according to the vehicle distance between the vehicle and the front vehicle, and the overtaking speed is reasonably controlled during overtaking, so that the safety of the vehicle during running is guaranteed.
一种基于超越模式的车辆超越控制方法与系统,其中,方法包括步骤:步骤1:在超越模式下获取车辆与前车之间的当前车距D;步骤2:判断当前车距D与车距阀值D1及车距阀值D2之间的大小,其中,车距阀值D1为车辆自适应巡航时的安全车距,车距阀值D1大于车距阀值D2,并且,在当前车距D≥车距阀值D1时,提醒驾驶员按照加速要求速度进行加速超车,在车距阀值D2≤当前车距D<车距阀值D1时,提醒驾驶员按照加速要求速度的40%‑60%进行加速超车,在当前车距D<车距阀值D2时,控制车辆维持在当前速度进行自适应巡航。该发明,能够根据车辆与前车之间的车距,确定车辆是否能够超车以及超车时合理控制超车车速,保障了车辆行驶时的安全性。
