Embodiment

[0113] The different embodiments in this application only use different actual water temperatures to calculate different duty cycle values, and the other aspects are the same. Therefore, in this application, only one of the actual water temperature values ​​is described, and other actual water temperatures are based on The formula can be obtained directly, therefore, other embodiments will not be described repeatedly in this application.

[0114] The request signal from the switch, the pressure signal from the pressure sensor and the water temperature signal from the engine water temperature sensor are input to the ECU module through the PWM hard line;

[0115] At the same time, the vehicle speed signal sent by the wheel speed sensor is input to the ECU module through the vehicle CAN line; the engine running status signal sent by the crankshaft speed signal is input to the ECU module through the engine LIN line;

[0116] The ECU module calculates the above signals to obtain a ...

Abstract

The invention relates to a stepless speed regulation radiator fan control assembly and method. The stepless speed regulation radiator fan control assembly comprises a power supply, an ECU module, a PWM control module, at least two MOSFETs and fans, wherein the number of the fans is the same as that of the MOSFETs; a switch, a pressure sensor and a water-temperature sensor are connected with the ECU module through PWM rigid lines; a wheel speed sensor is connected with the ECU module through a finished automobile CAN line; a crank shaft rotating speed signal is connected with the ECU module through an engine LIN line; the ECU module and the PWM control module are in double-way connection through PWM rigid lines of pins of the PWM control module; the output line of the PWM control module is connected with the MOSFETs; the MOSFETs are connected with a fan motor; a fan motor feedback signal output line is connected with the PWM control module.

Description

technical field [0001] The invention belongs to the field of radiator fans and controls, and in particular refers to a control assembly and a control method for a steplessly speed-adjustable radiator fan. Background technique [0002] With the increasing prosperity of the automobile market, customers are paying more and more attention to the fuel consumption and noise problems of automobiles. Energy saving and noise reduction have become the focus of automobile design. Especially for high-power engines and motors, it is very important to reduce energy consumption. [0003] At present, the electronic fans commonly used in domestic passenger cars are high-speed and low-speed electronic fans. The speed regulation method is generally series-parallel or resistive speed regulation. This speed regulation method cannot realize the characteristics of stepless speed regulation that the fan speed can be supplied according to demand. . Contents of the invention [0004] The purpose ...
