According to the temperature control method and control system shared by the power battery and the cab for the hybrid engineering vehicle, whether the power battery is heated through the small circulation of engine cooling circulating water or not is determined according to the temperature of a battery cell of the power battery, and the cooling circulating water flow of the small circulation is adjusted through an electronic flow valve; the opening degree of the electronic flow valve is controlled according to the temperature difference of the cooling circulating water before and after the cooling circulating water passes through the power battery measured by the two temperature sensors; determining whether the cab is heated according to whether the cab warm air is started simultaneously; whether a compressor cooling system is started to exchange heat with a battery heat exchanger or not is determined according to the temperature of a power battery cell, so that the power battery is cooled; whether the cab is cooled or not is determined according to whether cab cold air is started simultaneously or not. The control system comprises a cab temperature control system and a power battery temperature control system. The battery heat is equivalently supplied, so that the temperature of the battery cell is stably increased, and the service life is prolonged.
