Gas sensor system

A gas sensor system installed in a vehicle, the gas sensor system comprising:

• a gas sensor that performs concentration measurement of a measurement target gas in air;
• a heater that heats the gas sensor;
• an air intake port and an air discharge port that are connected to the gas sensor;
• a control device that performs heating control of operating the heater so as to heat the gas sensor;
• a storage device configured to store:
• a first temperature information indicating a temperature of the gas sensor;
• and
• a second temperature information indicating a temperature of a vehicle interior space of the vehicle from which the air intake port takes in air;
• and
• an air intake blocking means that prevents air intake from the air intake port, wherein
• the control device acquires the first temperature information and the second temperature information and performs the heating control based on the first temperature information and the second temperature information, and
• the control device performs air intake blocking control of blocking air intake from the air intake port and the heating control in a situation in which a magnitude of difference between the temperature of the gas sensor and the temperature of the vehicle interior space is equal to or greater than a heating differential threshold value, and the temperature of the gas sensor is lower than the temperature of the vehicle interior space.
