The invention relates to a new energy commercial vehicle braking energy recycling and electricity supplementing method and device.The method comprises the steps that when a braking signal of a target vehicle is obtained, the braking strength of the target vehicle is determined according to the braking signal, and the braking strength is used for representing the strength of needed braking force; according to a preset mapping relation table of the braking strength and vehicle braking strategies, a target braking strategy corresponding to the braking strength is determined, and the target braking strategy comprises the braking output proportion of a hydraulic braking system and the braking output proportion of a motor regenerative braking system; and controlling the target vehicle to execute the target braking strategy. By adopting the method, the braking strength is determined according to the braking signal of the vehicle, and the braking output of the hydraulic braking system and the braking output of the motor regenerative braking system are respectively controlled according to the braking strength, so that the possibility of excessive intervention of hydraulic braking force is reduced; and the recovery efficiency of the vehicle braking energy and the charging efficiency of the storage battery are improved.
