A control system that uses an algorithm to control the fan speed in a cooling system for an engine is disclosed. The algorithm is adapted to maintain a cooling medium at a set temperature instead of an operating temperature range of the cooling medium. The algorithm is also adapted to maintain a cooling medium at a set temperature and to build a cooling safety margin in response to an engine output torque percentage that is below an output torque percentage setpoint.

The cooling capacity of a cooling fan is made lower when a vehicle was not running while towing a trailer than when the vehicle was running while towing the trailer immediately before the end of a service of the vehicle, in activating the cooling fan after the end of the service.

A warm-up method based on a temperature control module, a vehicle, and a storage medium. The warm-up method based on the temperature control module comprises: entering a cold start mode; obtaining current temperature control parameters, the temperature control parameters comprising a current water temperature value, a current engine speed, and a current engine load; obtaining working parameters of a temperature control module according to the temperature control parameters; controlling the temperature control module according to the working parameters to adjust the water temperature to warm an engine, and updating the current water temperature value; and after the updated current water temperature value does not exceed a warm-up threshold, returning to the step of obtaining the current temperature control parameters to enter the next cycle.

An engine system is provided, including an engine having a water jacket, a circulation system that circulates coolant through the water jacket, and a controller. The circulation system includes a radiator passage including a heat exchanger, a bypass passage bypassing the heat exchanger, a flow rate control device, and a thermally-actuated valve connected to the radiator passage and that opens to allow the coolant to pass through the heat exchanger. When an engine load is below a first load, the controller controls the flow rate control device to adjust the coolant flow rate flowing through the water jacket according to the load, by closing the radiator passage and adjusting the coolant flow rate flowing through the bypass passage. When the load is above the first load, the controller controls the flow rate control device so that the coolant flows through each of the radiator passage and the bypass passage.

An engine cooling system is provided, which includes a water jacket through which coolant flows, a heat exchanger that cools the coolant, a first bypass passage that bypasses the heat exchanger and recirculates the coolant to the water jacket, a radiator passage that recirculates the coolant to the water jacket via the heat exchanger, and a flow control device that is installed at a location where a coolant passage branches into the first bypass passage and the radiator passage and performs a water flow control to adjust a coolant amount flowing into the water jacket by adjusting a coolant amount flowing through the first bypass passage. A thermally-actuated valve connected with the radiator passage via a second bypass passage is provided to the first bypass passage, and when this valve opens, the coolant flowing through the first bypass passage flows into the radiator passage through the second bypass passage.
