Definitions

  • problems such as notifying the user of an erroneous measurement result or causing the vehicle air conditioner to operate with an erroneous operation content based on the erroneous measurement result may occur.
  • the vehicle air conditioner 30 is a device for performing air conditioning of a vehicle interior.
  • the vehicle air conditioner 30 includes an air conditioning case 300, a fan 310, a particle filter 320, and a heat exchanger 330.
  • the inside air introduction unit 340 is an introduction port for introducing the air inside the vehicle compartment (hereinafter referred to as inside air) into the inside of the air conditioning case 300.
  • the outside air introducing unit 350 is an introducing port for introducing air outside the vehicle compartment (hereinafter, referred to as outside air) into the inside of the air conditioning case 300.
  • the inside air introduction unit 340 and the outside air introduction unit 350 are formed to be aligned in the upstream side portion of the air conditioning case 300.
  • the air flow in the introduction pipe 390 needs to occur.
  • the measurement of the particle concentration by the particle sensor 200 in the present embodiment is basically performed only in the situation where the air conditioning by the vehicle air conditioner 30 is being performed.
  • the control unit 220 has a measurement value acquisition unit 221, an external information acquisition unit 222, an abnormality determination unit 223, a correction unit 224, and an estimation unit 225 as functional components.
  • the vehicle air conditioner 30 has a value close to the value of the particle concentration of the external information, in other words, the value of the particle concentration of the external information having a high probability of being correct. Output a value close to,.
  • the notification unit 210 notifies the corrected value.
  • step S107 subsequent to step S106 the notification unit 210 notifies the user of the measurement result by the physical quantity sensor (particle sensor 200) and the maintenance recommendation time, and ends the series of processing.
  • external information that is information indicating the value of the physical quantity is acquired separately from the physical quantity measurement value acquired from the physical quantity sensor.
  • the physical quantity measurement value is corrected so as to approach the value of the physical quantity of the external information. Therefore, even when the physical quantity sensor is in a state of outputting an incorrect value due to an abnormality such as a failure, the external value is a value close to the value of the physical quantity of the external information, in other words, a value with high probability that is correct Output a value close to the value of the physical quantity of information. From the above, according to the present embodiment, even when an abnormality occurs in the physical quantity sensor, correct measurement results can be obtained.
  • the particle sensor 200 that measures suspended matter temporarily outputs an incorrect value even if there is no abnormality such as a failure in the particle sensor 200 due to condensation occurring in the particle sensor 200 in an environment where the humidity is high to some extent. There is. Also in such a case, if it is determined that there is an abnormality in the particle sensor 200 in the abnormality determination and the measurement value of the particle sensor 200 is corrected, a problem may occur on the contrary.
  • the estimation unit 225 indicates that the physical quantity sensor has an abnormality and the degree of difference between the value of the physical quantity acquired from the physical quantity sensor and the value of the physical quantity of the external information.
  • the maintenance recommendation time is estimated based on at least one of the frequency and the usage period of the physical quantity sensor.
  • the degree of difference between the value of the physical quantity acquired from the physical quantity sensor and the value of the physical quantity of the external information, the frequency at which the result of the abnormality determination indicates that the physical quantity sensor is abnormal is estimated based on at least one of the usage periods of the physical quantity sensor. Therefore, a particularly accurate maintenance recommendation time is estimated. Thereby, the user can know particularly appropriate maintenance recommendation time.
  • the external information acquisition unit 222 acquires the value of the physical quantity measured by the other vehicles 50 and 60 outside the vehicle 10 as external information.
  • an aspect may be adopted in which information indicating the value of physical quantity provided by an external information provider is acquired as external information.
