With the advancement of science and technology, the equipment system of the new energy vehicle temperature sensor is also constantly updated, which has adapted to the high-intensity requirements of the vehicle driving system, improved work efficiency, and facilitated modern driving.
What are the classifications of temperature sensors for new energy vehicles?
What is the function of the EGR exhaust gas circulation monitoring temperature sensor in the new energy vehicle temperature sensor?
How to monitor the OBD-Ⅱ system in the new energy vehicle temperature sensor?
The temperature sensors on automobiles are mostly negative temperature coefficients thermistors, such as engine intake temperature sensor, coolant temperature sensor, oil temperature sensor, automatic transmission and continuously variable transmission oil temperature sensor, dual-clutch transmission is responsible for monitoring the transmission oil bottom The G93 transmission oil temperature sensor for case oil temperature, the G509 temperature sensor responsible for monitoring the working oil temperature of the transmission clutch, the indoor temperature sensor of the air conditioner, the ambient temperature sensor, the evaporator temperature sensor, and the suspension air pump temperature sensor are all negative temperature coefficient heat Sensitive resistance. Its characteristic is that the higher the temperature of the measuring point, the lower the resistance value of the sensor, and the lower the output voltage signal. Take the Mazda intake air temperature sensor as an example. When the ambient temperature is -20℃, 20℃, and 60℃, the resistance values are 13.6~18.4kΩ, 2.21~2.69 kΩ, 0.493~0.6967kΩ, respectively.
EGR exhaust gas circulation monitoring temperature sensor,it is mainly used to detect the temperature change of the recirculated gas in the EGR valve and whether it works normally. Mainly used to remind the driver, it is generally installed on the intake port of the EGR valve. Under normal circumstances, the exhaust gas profile near the EGR valve is 100-200℃, high speed, 300-400℃ for heavy load, and about 50℃ when not working.
The OBD-Ⅱ system monitors combined electrical appliances, mainly to compare the information of the sensors that provide related information or common information, to determine which sensor is faulty, whether it is a short circuit or an open circuit, and other information. If the information of the coolant temperature sensor is compared with the information of the intake air temperature sensor or the time after startup, it can be concluded whether the information of the coolant temperature sensor is accurate, whether the sensor has a short circuit or open circuit fault. Therefore, the OBD-Ⅱ system will leave a fault code after the coolant temperature sensor is short-circuited.
