Abstract

The invention relates to the technical field of new-energy commercial vehicles, in particular to a hybrid power system of a heavy truck and a control method. The hybrid power system comprises a powermodule, a whole vehicle controller module, a transmission module, an engine and a power-generating motor, wherein the power module comprises a power manager and a storage battery; the power manager iselectrically connected with the storage battery; the power manager is electrically connected with the whole vehicle controller module, the transmission module, the engine and the power-generating motor, respectively; the whole vehicle controller module is electrically connected with the transmission module and the engine, respectively; the transmission module comprises a first clutch, a second clutch and a transmission box; the engine is connected with the transmission box through the first clutch; the engine comprises a fly wheel; a gear is arranged on the power-generating motor. Through useof the power-generating motor, motor equipment which can be used both as a generator and as a motor can achieve reduction in the volume of the motor; in addition, kinetic energy recovery is achievedin the cases of braking and the like.

Description

technical field [0001] The invention relates to the technical field of new energy commercial vehicles, in particular to a hybrid power system and a control method of a heavy truck. Background technique [0002] Due to increasingly stringent exhaust gas regulations and the need for vehicle owners to reduce operating costs, increasing demands are placed on motor vehicles with regard to their fuel consumption and pollutant emissions, while at the same time a higher degree of driving comfort is desired sex. For this purpose, it is known from practice to equip motor vehicles with automatic stop / start devices, by means of which the internal combustion engine can be automatically deactivated and started in predetermined states. Thus, the internal combustion engine is automatically deactivated, for example, when no driving force is required (for example, when stopped at a traffic light). As soon as driving force is required again, ie when the traffic light turns "green" and the ...
