The invention provides a vehicle braking control method and device, electronic equipment and a vehicle, and the method comprises the steps: obtaining the execution deceleration of the vehicle at the current moment, the first speed of the vehicle, the second speed of a front target object, and the relative distance between the vehicle and the front target object in the electric braking process of the vehicle; whether the execution deceleration at the current moment meets the safety braking condition or not is judged, and if not, the vehicle is controlled to execute hydraulic braking, so that the execution deceleration at the current moment is compensated, real-time judgment of the safety braking condition in the braking process of the electric brake is achieved, and the braking safety of the electric brake is improved. The hydraulic braking is involved for compensation only under the condition that the safety braking condition is not met, the situation that hydraulic braking is involved under the condition that the safety braking condition is met is avoided, and then direct intervention of hydraulic braking is avoided; the problems that in the prior art, hydraulic braking needs to be involved in a small braking scene, so that the whole vehicle shakes, the body feeling is uncomfortable, and the energy recovery efficiency is low are solved.

    本申请提供一种车辆制动控制方法、装置、电子设备及车辆,该方法通过在车辆电刹制动的过程中,获取在当前时刻下车辆的执行减速度、车辆的第一速度、前方目标对象的第二速度、以及车辆与前方目标对象之间的相对距离,进而判断当前时刻的执行减速度是否满足安全制动条件,并在不满足的情况下,控制车辆执行液压制动,以对当前时刻的执行减速度进行补偿,实现了在电刹制动过程中安全制动条件的实时判断,以仅在不满足安全制动条件的情况下介入液压制动进行补偿,避免了在满足安全制动条件的情况下介入液压制动,进而避免了液压制动的直接介入,解决了现有技术中小制动场景下液压制动均要介入所导致的整车抖动、体感不舒适和能量回收效率低的问题。
