The invention discloses a vehicle running speed determination method and device and a domain controller. The method comprises the steps that an estimated braking value of a first vehicle is determined according to the historical driving state of the first vehicle and the driving state at the current moment, the estimated braking value is used for representing the estimated value of the deceleration of the first vehicle during driving at other moments after the current moment, and the first vehicle is the vehicle driving in front of the first vehicle; the first vehicle and the own vehicle run on the same lane according to the same running direction; according to the first speed of the first vehicle at the current moment, the estimated braking value of the first vehicle and the safety braking threshold value of the vehicle, the expected speed of the vehicle is determined; and according to the maximum allowable braking value of the vehicle and the target acceleration, the expected speed of the vehicle is adjusted, and the target driving speed is obtained. The technical problem that the vehicle driving efficiency is low is solved.

    本申请公开了一种车辆行驶速度的确定方法、装置及域控制器。其中,该方法包括:根据第一车辆的历史行驶状态与当前时刻的行驶状态,确定第一车辆的预估制动值,其中,预估制动值用于表示第一车辆在当前时刻之后的其他时刻行驶时的减速度的预估值,第一车辆是行驶在自车前方的车辆,第一车辆与自车按照相同的行驶方向行驶在同一车道上;根据第一车辆在当前时刻的第一速度、第一车辆的预估制动值和自车的安全制动阈值,确定自车的期望速度;根据自车的最大允许制动值和目标加速度,对自车的期望速度进行调整,得到目标行驶速度。本申请解决了车辆驾驶效率较低的技术问题。
