The invention relates to the field of rail transit vehicles, and discloses a vehicle braking keeping relieving method and device, a storage medium and electronic equipment. The method comprises the steps that starting acceleration is determined according to traction force at the starting moment, holding braking force at the starting moment and starting resistance; according to the starting acceleration and a preset starting condition, the critical time for sending out a brake release keeping instruction is determined; determining a target mitigation level through a preset level determination model according to the critical time; according to the target release level and a preset impact rate limit threshold value, determining instruction sending time for keeping a brake release instruction; and starting of the target vehicle is controlled according to the target release level and the instruction sending time. The time from the time when a signal system sends a brake release keeping instruction to the time when the train is started is greatly shortened, and the train starting speed is increased; the traction force at the train starting moment can be reduced, so that the train starting impact is reduced.

    本申请涉及轨道交通车辆领域,公开了一种车辆保持制动缓解方法、装置、存储介质及电子设备。所述方法包括:根据启动时刻的牵引力和启动时刻的保持制动力以及启动阻力确定启动加速度;根据所述启动加速度和预设启动条件确定发出保持制动缓解指令的临界时间;根据所述临界时间通过预设级位确定模型确定目标缓解级位;根据所述目标缓解级位和预设冲击率限制阈值确定保持制动缓解指令的指令发送时间;根据所述目标缓解级位和所述指令发送时间控制目标车辆的启动。大幅缩短从信号系统发送保持制动缓解指令到列车启动的时间,提高了列车启动速度;还可降低列车启动时刻的牵引力,从而降低列车启动冲击。
