The invention discloses a vehicle speed control method, device and equipment, a medium and a product. The method comprises the following steps: determining each current candidate planning state of a current planning position point in a slope road section based on a current cruise control speed; the candidate planning state comprises a candidate planning speed and a candidate planning gear; determining a current target planning state for the current planning position point based on the target planning speed of the previous planning position point, the gradient of the gradient road section, the current candidate planning state, the current battery state and a preset distance step length; and based on the current target planning state, the current motor demand torque is determined for the current planning position point, and the current motor demand torque is used for controlling the speed of the vehicle. According to the technical scheme, the speed of the vehicle running on the slope road section in the cruise control state is re-planned and controlled, and the energy consumption of the vehicle is reduced.

    本发明公开了一种车辆的速度控制方法、装置、设备、介质及产品。该方法包括:基于当前定速巡航速度,确定坡度路段中当前规划位置点的各当前候选规划状态;候选规划状态包括候选规划速度和候选规划档位;基于上一规划位置点的目标规划速度、坡度路段坡度、当前候选规划状态、当前电池状态和预设距离步长,为当前规划位置点确定当前目标规划状态;基于当前目标规划状态,为当前规划位置点确定当前电机需求扭矩,当前电机需求扭矩用于控制车辆的速度。上述技术方案实现了定速巡航状态下车辆在坡度路段行驶时的速度的重新规划和控制,降低了车辆能耗。
