The invention discloses a vehicle following distance determination method. The method comprises the following steps that: the driving speed of a current vehicle is acquired; the driving speed is compared with a preset first speed and a preset second speed, so that a first comparison result can be obtained, and a target deceleration is determined according to the first comparison result, the presetsecond speed is greater than the preset first speed; the driving speed is compared with a preset third speed and a preset fourth speed, so that a second comparison result is obtained, and a target acceleration is determined according to the second comparison result, and the preset fourth speed is greater than the preset third speed; and the target vehicle following distance of the current vehicleis calculated according to the target acceleration and the target deceleration. According to the method, the vehicle following distance is determined according to the driving speed. Under the condition that a vehicle following distance is set according to experience, when the set distance is unreasonable, a vehicle following auxiliary function may cause vehicle rear-end collision due to system faults. With the method of the invention adopted, the above problem can be avoided.
本发明公开了一种跟车距离的确定方法,包括:获取当前车辆的行驶速度;将所述行驶速度与预设的第一速度和预设的第二速度进行比较,得到第一比较结果,依据所述第一比较结果确定目标减速度,其中,所述预设的第二速度大于所述预设的第一速度;将所述行驶速度与预设的第三速度和预设的第四速度进行比较,得到第二比较结果,依据所述第二比较结果确定目标加速度,其中,所述预设的第四速度大于所述预设的第三速度;依据所述目标加速度和所述目标减速度计算所述当前车辆的目标跟车距离。上述方法中,跟车距离的确定依据行驶速度进行确定,避免了依据经验进行跟车距离设定,在设定不合理时,跟车辅助功能可能在由于系统故障导致车辆追尾的问题。
