Abstract
The invention provides an air volume control system for a cooling fan of a radiator. The air volume control system comprises a fan motor and a fan control module, wherein the fan control module is arranged on the circuit of the fan motor and is powered by a relay controlled by a start key; the fan control module receives a temperature signal sent by a motor controller through a CAN; a temperature sensor is arranged on each of the motor controller and the motor; and the motor controller receives a signal from the temperature sensor, processes the received signal and then outputs a feedback signal through the CAN to the fan control module, and the fan control module controls the rotational speed of the fan motor through duty cycle PWM so as to control the rotational speed of the fan. The air volume control system reduces the consumption of electric energy while guaranteeing the heat dissipation demand of the complete vehicle, and therefore, increases the endurance mileage of the vehicle.
Description
Technical field
The invention belongs to technical field of automobile electronic control, is related to a kind of pure electric commercial vehicle cooling fan, especially a kind of cooling fan air quantity control system of radiator.
Background technology
The cooling fan that commercial car field often uses at present is Mechanical Driven control mode, cooling fan is with fixed rotating speed full-speed operation, to ensure to radiate to thermal parts such as electromotor, motor, electric machine controllers, due to the caloric value of each part it is closely related with vehicle applying working condition, the real-time full-speed operation of fan can cause heat dissipation capacity superfluous, for pure electric commercial vehicle, course continuation mileage shortening is resulted in.Secondly, fan full-speed operation, to pure electric commercial vehicle, can cause car load noise to significantly increase.Again, fan electromotor frequently skips to full rotating speed from zero-turn speed, or skips to zero-turn speed from full rotating speed, shortens can fan life.
The content of the invention
The deficiency on pure electric commercial vehicle is applied for solving traditional cooling fan, fan speed-regulating is realized, it is ensured that car load radiating requirements, the present invention proposes a kind of cooling fan air quantity control system of radiator.
The technical solution used in the present invention is as follows：The present invention proposes a kind of cooling fan air quantity control system of radiator, including fan electromotor and fan control module；
Fan control module is arranged on the circuit of fan electromotor, and fan control module is powered by the relay that initiation key is controlled；
Fan control module receives the temperature signal that electric machine controller is sent by CAN network；
Electric machine controller and fan electromotor are provided with temperature sensor；
Electric machine controller, receives temperature sensor signal, to after temperature sensor signal process, by CAN network output feedback signal to fan control module, blower module controls the rotating speed of fan electromotor by pwm pulse width modulated duty cycle, so as to control rotation speed of the fan.
Beneficial effect：The present invention arranges the corresponding relation of fan electromotor, motor temperature, electric machine controller temperature and fan motor rotational speed, ensure heat dissipation capacity needed for car load, realized to fan electromotor voltage linear speed governing by control module, it is ensured that saves energy is consumed while car load radiating requirements, increase vehicle course continuation mileage.
Description of the drawings
Fig. 1 is the control principle drawing of the present invention.
Specific embodiment
A kind of cooling fan air quantity control system of radiator as shown in Figure 1, fan control module receives motor and the in good time temperature information of electric machine controller by CAN network, when both arbitrary temperature reach fan work design temperature, blower module adjusts rotation speed of the fan to reach system radiating demand using PWM mode in good time.
For example, set electric machine controller temperature adjusting scope：40-50℃；Motor temperature modification scope：70-110℃；According to fan self-radiating ability, radiating fan rotation speed adjusting range is set：10%-100%.Pulse duty factor determines rotation speed of the fan, when electric machine controller temperature reaches 40 DEG C, or motor temperature is when reaching 70 degree, make rotation speed of the fan reach 10% by pwm pulse width modulated duty cycle, rotation speed of the fan with both temperature changes as foundation, with higher temperature as rotation speed of the fan basis of design in the course of work, when electric machine controller temperature reaches 50 degree, or motor temperature, when reaching 110 degree, rotation speed of the fan reaches 100%, and rotation speed of the fan is linear with temperature.
