The invention discloses a vehicle speed control method and device, and vehicle electric control equipment. The method comprises steps that when a deceleration instruction is received, a current vehicle speed value of a target vehicle is detected; a vehicle speed prediction model and target deceleration parameters are determined, the vehicle speed prediction model is used for predicting vehicle speed control parameters of the target vehicle in a future preset time period, and the target deceleration parameters at least comprise deceleration duration, a deceleration control time domain, a deceleration prediction time domain and a deceleration difference value; a deceleration reference quantity of the target vehicle during deceleration is determined, the deceleration reference quantity is used for indicating the target vehicle to calculate a deceleration distribution value of the vehicle during deceleration according to the deceleration duration; the target vehicle is controlled to decelerate from the current vehicle speed value to the vehicle speed set value based on the target deceleration parameter, the vehicle speed control parameter and the deceleration reference quantity. The method is advantaged in that technical problems that during emergency braking of a vehicle, the vehicle speed is suddenly increased by fixedly decelerating to decelerate, and the emergency braking effect is reduced are solved.

    本发明公开了一种车速控制方法及装置、车辆电控设备。其中,该方法包括:在接收到减速指令时,检测目标车辆的当前车速值;确定车速预测模型以及目标减速参数,其中,车速预测模型用于预测未来预设时间段中目标车辆的车速控制参数,目标减速参数至少包括:减速时长、减速控制时域、减速预测时域和减速差值;确定目标车辆在减速时的减速参考量,其中,减速参考量用于指示目标车辆根据减速时长计算出在车辆减速时的降速分配值;基于目标减速参数、车速控制参数和减速参考量,控制目标车辆从当前车速值减速至车速设定值。本发明解决了车辆在紧急制动时,通过固定减速至进行减速会造成车速突增,降低紧急制动效果的技术问题。
