The invention discloses a cooling system of a hybrid sanitation vehicle and a control method, the cooling system comprises a high-temperature cooling branch and a low-temperature cooling branch, the high-temperature cooling branch is provided with an engine, the low-temperature cooling branch and the high-temperature cooling branch are connected in parallel and comprise a first cooling branch, a second cooling branch and a third cooling branch, and the first cooling branch, the second cooling branch and the third cooling branch are connected in parallel. The first cooling branch is provided with a first controller and a driving motor, the second cooling branch is provided with an oil pump motor and a fan motor, and the third cooling branch is provided with a water pump motor; the heat dissipation device is matched with the high-temperature cooling branch, the first cooling branch, the second cooling branch and the third cooling branch through control valves; and the control device communicates with the control valve and is used for controlling the on-off state of the control valve, so that the heat dissipation device selectively communicates with the cooling branches to form a cooling loop. According to the cooling system provided by the embodiment of the invention, the heat dissipation device is communicated with the plurality of cooling branches, so that the integration level of the cooling system is high, and the heat dissipation efficiency is improved.
