New energy vehicle tail lamp warning control method, device based on method and vehicle

The invention relates to a new energy vehicle taillight warning control method, a device based on the method and an automobile, and the control method comprises the steps that by monitoring the state of an accelerator pedal, the real-time vehicle speed and the energy recovery rate, when the accelerator pedal is in a closed state, and the real-time vehicle speed and the energy recovery rate reach a certain threshold value, a controller turns on a brake warning lamp, and the brake warning lamp is turned on; compared with the prior art that when the running vehicle is in the energy recovery state and the vehicle speed is rapidly reduced, the vehicle speed reduction warning system has the advantages that when the vehicle is in the energy recovery state and the vehicle speed is reduced, the vehicle speed reduction warning system can give a deceleration warning to the rear vehicle, so that the traffic accident is avoided. The probability of traffic accidents is greatly reduced; the device is used for realizing judg
