Vehicle power limit reminding triggering method and device, controller, vehicle and medium

The invention relates to the technical field of automobile power systems, and discloses a whole vehicle power limit reminding triggering method and device, a controller, a vehicle and a storage medium. The actual maximum output electric power of a target vehicle power system and the standard maximum output power when all power parts in the power system do not have faults are obtained in real time; according to the method, the whole vehicle power limit value of the target vehicle is determined according to the preset power limit threshold value, and then the whole vehicle power limit reminding is determined to be triggered when the number of times that the whole vehicle power limit value is smaller than the preset power limit threshold value meets the preset condition within the preset target duration. Visibly, from the perspective of the whole target vehicle, whether the whole vehicle power limit reminding is triggered or not is judged according to the actual maximum output electric power and the standard max
