Abstract: A method for controlling a hybrid vehicle, includes: acquiring a traveling parameter of the hybrid vehicle; controlling the engine, the driving motor, and the electric generator according to the traveling parameter, to enable the engine to operate in an economic zone by controlling charging and discharging of the power battery; comparing equivalent fuel consumptions of a series mode, a parallel mode, and an EV mode of the hybrid vehicle, and determining a minimum equivalent fuel consumption among the equivalent fuel consumptions; and selecting one of the series mode, the parallel mode, or the EV mode having the minimum equivalent fuel consumption as a current operation mode of the hybrid vehicle. The hybrid vehicle includes the engine and a driving motor outputting power to a wheel end, an electric generator generating electricity, and the power battery supplying electricity to the driving motor and charged by the electric generator or the driving motor.

Abstract: The present disclosure provides a power conservation control method and apparatus for a vehicle, and a readable storage medium. The method part includes: obtaining a minimum predicted ambient temperature within a preset time period; determining a minimum ambient temperature according to the minimum predicted ambient temperature and a current ambient temperature; if the minimum ambient temperature is less than or equal to a first preset temperature threshold, determining a minimum power conservation point of a traction battery according to the minimum ambient temperature; and performing mandatory power conservation control on the vehicle according to the minimum power conservation point, so that the remaining power of the traction battery is not less than the minimum power conservation point.
