Eavesdropping on vehicle errors
The “Vehicle-to-Maintenance” system can detect interference noises with two microphones and an evaluation unit.
Eavesdropping on vehicle errors
The company V2M, based in the US state of Delaware, wants to use its “Vehicle-to-Maintenance” system to detect faults in the engine and chassis before they develop into serious defects. To do this, two microphones attached to the bottom of the vehicle analyze the noise of the brakes or other components in the car. In this way, defects can be localized more precisely than with conventional onboard sensors. The noises are digitized and forwarded to the evaluation unit, which is also mounted on the vehicle floor. An artificial intelligence then assigns the noises to specific types of damage and sounds an alarm if this occurs. If problems are detected, the vehicle owner and/or their mechanic are notified via an app and a web-accessible dashboard.
According to the manufacturer, warnings could also be sent to vehicle manufacturers, fleet operators and to the vehicle's existing onboard diagnostic system, which can react in certain cases, for example by reducing speed, if impending damage poses potential dangers at higher speeds. V2M is intended for use in both combustion and electric vehicles. The current prototype was tested in a Tesla sedan. A market-ready version should be available by June of this year. The company says it is already in talks with car manufacturer Ferrari, which wants to include the system as standard equipment in its vehicles.
