The invention provides a vehicle speed limiting control method and device, electronic equipment, a storage medium and a vehicle, and relates to the technical field of vehicle control. The method comprises the steps that a vehicle speed sensor signal collected by a vehicle speed sensor is obtained, and the real-time speed of the vehicle is calculated based on the vehicle speed sensor signal; comparing the real-time speed of the vehicle with a preset speed limit value to obtain a speed comparison result; vehicle speed limiting control is conducted according to the speed comparison result, and the vehicle speed limiting control comprises first speed limiting control over an engine through an engine control unit ECU and/or second speed limiting control over a retarder through a gearbox control unit TCM; wherein the first speed limiting control is used for controlling the fuel injection quantity of the engine to be only related to the load rate, and the second speed limiting control is used for controlling the brake torque of the retarder to be adjusted to be interlocked with the load rate of the engine from being interlocked with an accelerator. According to the invention, the vehicle can realize automatic speed-limiting driving under the downhill working condition.
本申请提供了一种车辆限速控制方法、装置、电子设备、存储介质及车辆,涉及车辆控制技术领域,方法包括:获取车速传感器采集的车速传感器信号,并基于车速传感器信号计算车辆实时速度;对比车辆实时速度与预设限速值,得到速度对比结果;根据速度对比结果指示进行车辆限速控制,车辆限速控制包括发动机控制单元ECU对发动机的第一限速控制,和/或,变速箱控制单元TCM对缓速器的第二限速控制;其中,第一限速控制用于控制发动机喷油量只与负荷率相关,第二限速控制用于控制缓速器制动力矩从与油门互锁调整为与发动机负荷率互锁。本申请可使车辆在下坡工况实现自动限速行驶。
