Title:
OIL TEMPERATURE MEASUREMENT DEVICE, CONTROL METHOD, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/025077
Kind Code:
A1
Abstract:
An oil temperature measurement device, a control method, and a vehicle. Said device is configured to measure oil temperature and comprises: a thermistor (RT), a pull-up circuit (10), and a controller (20). The thermistor (RT) and the pull-up circuit (10) in series connection between a power supply (Vcc) and a ground terminal (GND). The pull-up circuit (10) comprises at least one first pull-up resistor (RP0), at least one second pull-up resistor (RP1), and at least one switch module (30) that is electrically connected to the at least one second pull-up resistor (RP1) in one-to-one correspondence. At least one first pull-up resistor (RP0) and at least one second pull-up resistor (RP1) are in series or in parallel connection between the thermistor (RT) and the power supply (VCC). The controller (20) is configured to determine the oil temperature according to the resistance value of the thermistor (RT), and, according to the oil temperature, control each switch module (30) among the at least one switch module (30) to turn on or off so as to correct the resistance value of a pull-up resistor in the pull-up circuit.
