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.
