Radiator fan control module
Control strategy
Water temperature: 90°C~100°C, target temperature: 95°C, PID regulation, i.e. fan begins to accelerate
when the temperature is more than 95°C, or vice versa
Torque oil temperature: 105°C~110°C, linear adjustment, i.e. fan operates at the minimum speed when
the temperature is not more than 105°C and other temperatures are not in the adjustable range; fan
operates at the maximum speed when the temperature is more than 110°C; when the temperature is
between 105°C~110°C, an corresponding speed can be achieved through linear scale calculation.
Air-air intercooler: temperature control node: 40,Fmin; 55,F80%; 70,80%; 75,Fmax;
