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 ...
