Technical Field

Background
In the running process of the engine, the thermal state of the engine changes along with the change of the external environment and the working condition of the whole vehicle. In order to ensure that the engine can work normally, the thermal state of the engine needs to be adjusted in real time. For example, when the engine is operated in a low temperature environment (e.g., winter in the north) for a long time or is driven at a high speed with strong windward, the temperature of the engine needs to be increased. In contrast, when the engine is operated in a high temperature environment for a long time, especially in a high temperature idling condition, the temperature of the engine will be very high, and at this time, the temperature of the engine needs to be reduced.
At present, most of cooling fans used by passenger vehicles are electronic fans, and the electronic fans have the characteristics of energy conservation and noise reduction and are widely applied to small-displacement passenger vehicles. However, for a passenger car equipped with a V6TD large-displacement engine, the requirement for heat dissipation efficiency is more strict due to the large weight of the whole car, the large load of the engine and the thick cooling module. The electronic fan cannot meet the heat dissipation requirement of the engine of the vehicle due to the structural limitation of the electronic fan.

According to the technical scheme provided by the embodiment of the invention, the rotating speed of the electric control silicone oil mechanical fan can be adjusted according to the parameter information of the whole vehicle, so that the heat dissipation requirement of a vehicle engine on the fan under most working conditions can be met, and the purposes of energy conservation and noise reduction are achieved.

The advantage of setting up like this lies in, can confirm the target rotational speed of automatically controlled silicon oil mechanical fan more accurately according to whole car parameter information.
For example, the vehicle parameter information of the vehicle collected by the engine control unit may include vehicle owner parameter information and vehicle correction parameter information, where the vehicle owner parameter information may be understood as a main reference parameter for determining a target rotation speed of the electrically controlled silicone oil mechanical fan, and the vehicle correction parameter information may be understood as a reference parameter for adjusting and correcting the target rotation speed of the electrically controlled silicone oil mechanical fan determined based on the vehicle owner parameter information.

And then, the initial rotating speed can be further adjusted and corrected according to the finished automobile correction parameters, and the corrected initial rotating speed is used as the target rotating speed of the electric control silicone oil mechanical fan. Optionally, when the entire vehicle main parameter information is multiple, the initial rotation speed corresponding to the entire vehicle main parameter information may be determined based on each entire vehicle main parameter information, and then, the maximum initial rotation speed of the multiple initial rotation speeds is used as the final initial rotation speed of the electrically controlled silicone oil mechanical fan determined based on all the entire vehicle main parameter information. Optionally, when the finished automobile correction parameter information is multiple, the initial rotating speeds may be corrected based on the finished automobile correction parameters, and the maximum value of the corrected initial rotating speeds is used as the target rotating speed of the electric control silicone oil mechanical fan.

Optionally, when the main parameter information of the whole vehicle is multiple, the main parameters of the whole vehicle may be further grouped, for example, at least two pieces of the main parameter information of the whole vehicle are grouped, a correspondence table between each piece of the main parameter information of the whole vehicle and the rotation speed is obtained, the rotation speed corresponding to the collected main parameter information of the whole vehicle is determined according to the correspondence table, and the maximum rotation speed in the rotation speeds determined based on the main parameter information of the whole vehicle is used as the initial rotation speed of the electrically controlled silicone oil mechanical fan.

Optionally, when the target rotation speed is greater than the limit rotation speed, the electronic control silicone oil mechanical fan is controlled to rotate based on the limit rotation speed. The advantage that sets up like this lies in, when satisfying the heat dissipation demand of vehicle engine to the fan under most operating modes, can guarantee automatically controlled silicon oil mechanical fan's life, avoids automatically controlled silicon oil mechanical fan to rotate the trouble that produces with the rotational speed that is greater than limit speed.
