Embodiment approach 1
[0020] figure 1 It is a block diagram showing the thermostat control device 100 according to Embodiment 1 of the present invention. The thermostat control device 100 will be specifically described below.
[0021] The thermostat control device 100 outputs a thermostat control voltage to the thermostat 10 so that the thermostat 10 can adjust the temperature of the coolant of the engine appropriately. The thermostat control device 100 includes: a sensor group 1 , a thermostat correction value calculation unit 6 , a thermostat voltage base value calculation unit 7 , a PID calculation unit 8 , and a controller 9 .
[0022] The sensor group 1 includes a plurality of sensors: an intake air temperature sensor 2 , a vehicle speed sensor 3 , a rotational speed sensor 4 , a water temperature sensor 5 and a load sensor 11 . The intake air temperature sensor 2 detects the intake air temperature of the engine, the vehicle speed sensor 3 detects the speed of the vehicle, the rotational sp...
Embodiment approach 2
[0057] Figure 6 A block diagram showing a thermostat control device 100' according to Embodiment 2, Figure 7 The control method of the thermostat control device according to Embodiment 2 is shown, and the same blocks and steps as those in Embodiment 1 are denoted by the same reference numerals. Only the parts of Embodiment 2 that are different from Embodiment 1 will be described below.
[0058] Such as Figure 6 As shown, the thermostat control device 100' further includes a battery voltage correction value calculation unit 11. The battery voltage correction value calculation unit 11 has a battery voltage correction table T2 with the battery voltage VB as a variable, and refers to the battery voltage correction table T2 based on the battery voltage VB. The table T2 outputs the battery voltage correction value Cvb to the controller 9 . Therefore, when calculating the thermostat control voltage Vctl, the controller can take the battery voltage VB of the car into considerati...
