The invention discloses a hybrid electric vehicle waste heat recovery system, a control method and a vehicle, and belongs to the technical field of energy recovery. The hybrid electric vehicle waste heat recovery system comprises an engine exhaust circulation system, a waterway circulation system, a warm air circulation system, a motor circulation system, a battery circulation system, a battery charging heating circulation system and an engine cooling circulation system. According to the waste heat recovery system of the hybrid electric vehicle, the control method and the vehicle, heat of an engine exhaust system is effectively utilized, cooling liquid of a warm air system is rapidly heated, the heating requirement of a passenger compartment is met, and under the low-temperature environment condition, particularly under the extremely cold climate condition, the discharging efficiency of a battery is low, and the battery is not damaged. The heat of the exhaust system can be actively recovered for heating the passenger compartment of the warm air system by controlling the engine to work, so that the use of a PTC heater is reduced, the energy consumption is reduced, and the worry of a user on the endurance mileage in winter is relieved; and fourthly, the motor waste heat recovery function is reserved, the battery is heated, and the discharging efficiency of the battery is improved.
