Diagnostic systems and methods of vehicles using olfaction
A vehicle system includes: at least one of: (a) a particulate matter sensor configured to measure an amount of particulate within a passenger cabin of a vehicle; and (b) a volatile organic compounds (VOC) sensor configured to measure an amount of VOCs within the passenger cabin of the vehicle; and a control module configured to, based on at least one of the amount of particulate and the amount of VOCs within the passenger cabin of the vehicle, diagnose at least one of: a characteristic of the vehicle; presence of a chemical in the passenger cabin of the vehicle; occurrence of an event within the passenger cabin of the vehicle; and a remaining life of engine oil of the vehicle.
1. A vehicle system, comprising:
at least one of:
a particulate matter sensor configured to measure an amount of particulate within a passenger cabin of a vehicle; and
a volatile organic compounds (VOC) sensor configured to measure an amount of VOCs within the passenger cabin of the vehicle; and
a control module configured to, based on at least one of the amount of particulate and the amount of VOCs within the passenger cabin of the vehicle, diagnose
a characteristic of the vehicle;
wherein the characteristic includes at least one of:
a fault of a catalytic converter;
engine coolant leak;
an engine oil leak;
rubbing of a belt or a hose;
overheating of a clutch;
a fault associated with one or more brakes; and
overloading of the vehicle.
2. The vehicle system of claim 1 wherein the control module is configured to store the diagnosis in memory of the vehicle.
3. The vehicle system of claim 1 wherein the control module is configured to transmit the diagnosis to a remote device.
4. The vehicle system of claim 3 wherein the control module is configured to transmit the diagnosis to the remote device via a wireless transceiver of the vehicle.
5. The vehicle system of claim 3 wherein the control module is configured to transmit the diagnosis to the remote device via a wired connection between the remote device and a port of the vehicle.
6. The vehicle system of claim 1 wherein the control module is further configured to, based on the at least one of the amount of particulate and the amount of VOCs within the passenger cabin of the vehicle, diagnose at least one of:
presence of a chemical in the passenger cabin of the vehicle;
occurrence of an event within the passenger cabin of the vehicle; and
a remaining life of engine oil of the vehicle.
7. The vehicle system of claim 1 wherein the control module is configured to make the diagnosis further based on at least one of a baseline amount of particulate from before the diagnosis and a baseline amount of VOCs within the passenger cabin of the vehicle from before the diagnosis.
8. The vehicle system of claim 6 wherein the control module is configured to, based on the at least one of the amount of particulate and the amount of VOCs within the passenger cabin of the vehicle, diagnose the occurrence of an event within a passenger cabin of the vehicle.
9. The vehicle system of claim 8 wherein the event is one of smoking, presence of an animal, and presence of food.
10. The vehicle system of claim 6 wherein the control module is configured to, based on the at least one of the amount of particulate and the amount of VOCs within the passenger cabin of the vehicle, diagnose the presence of a chemical in the passenger cabin of the vehicle.
11. The vehicle system of claim 6 wherein the control module is configured to, based on the at least one of the amount of particulate and the amount of VOCs within the passenger cabin of the vehicle, diagnose the remaining life of engine oil of the vehicle.
12. A method comprising:
at least one of:
measuring an amount of particulate within a passenger cabin of a vehicle; and
measuring an amount of a volatile organic compounds (VOCs) within the passenger cabin of the vehicle; and
based on at least one of the amount of particulate and the amount of VOCs within the passenger cabin of the vehicle, diagnosing at least one of:
a characteristic of the vehicle;
presence of a chemical in the passenger cabin of the vehicle;
occurrence of an event within the passenger cabin of the vehicle; and
a remaining life of engine oil of the vehicle,
wherein the diagnosing includes, based on the at least one of the amount of particulate and the amount of VOCs within the passenger cabin of the vehicle, diagnosing a characteristic of the vehicle, and
wherein the characteristic includes at least one of:
a fault of a catalytic converter;
engine coolant leak;
an engine oil leak;
rubbing of a belt or a hose;
overheating of a clutch;
a fault associated with one or more brakes; and
overloading of the vehicle.
13. A vehicle system, comprising:
at least one of:
a particulate matter sensor configured to measure an amount of particulate within a passenger cabin of a vehicle; and
a volatile organic compounds (VOC) sensor configured to measure an amount of VOCs within the passenger cabin of the vehicle; and
a control module configured to, based on at least one of the amount of particulate and the amount of VOCs within the passenger cabin of the vehicle, diagnose a characteristic of the vehicle,
wherein the characteristic includes a fault in a battery of the vehicle.
