The invention relates to a hybrid vehicle integrated thermal management system based on a multi-way valve, and belongs to the technical field of new energy vehicle thermal management systems. The integrated heat management system of the hybrid electric vehicle comprises a vehicle control unit, a battery temperature control module used for adjusting the temperature of a battery pack, an engine cooling module used for absorbing heat emitted by an engine and carrying waste heat of the engine, and an electric drive cooling module used for absorbing heat emitted by a motor and carrying waste heat of the motor. The heat distribution instruction is sent to the electric drive cooling module, the engine cooling module and the battery temperature control module through the vehicle control unit, when a battery pack and a passenger compartment have heating requirements, waste heat is fully utilized to heat the battery pack and the passenger compartment, heat of cooling liquid of all loops is coupled into a battery cooling loop in a direct heat exchange mode, and the cooling efficiency of the battery pack and the passenger compartment is improved. And available waste heat is distributed according to different working modes while the waste heat utilization efficiency is improved.
