Vehicle diagnostic and prognostic methods and systems
View Patent ↗Method for predicting failures in vehicular components includes mounting sensors on the vehicle which provide data affected by the operation of the components, obtaining data from the sensors, detecting patterns in the obtained data on the vehicle, analyzing the detected patterns to predict failure of any component, and informing the user, owner, dealer and/or manufacturer of the vehicle about the predicted failure to enable preventative and corrective action to be taken. A vehicle with remote telematics capability includes sensors arranged to provide data about conditions of the vehicle or components, a processor for receiving data provided by the sensors and converting the data into an output constituting a signal about a diagnostic condition of the vehicle or component(s), and a communications unit arranged to transmit the signal. The communications unit can establish a communications channel with a dealer or manufacturer of the vehicle at a location remote from the vehicle.
1. A method for predicting impending failures in one or more of a plurality of components or subsystems on a vehicle to prevent a breakdown of the vehicle that could result in an inability to operate the vehicle, comprising:
mounting sensors on the vehicle, the sensors providing data which is affected by the operation of the components or subsystems, the sensors being selected and arranged such that the data provided by the sensors is different for different operating states of each of the plurality of components and subsystems;
obtaining data from the sensors during operation of the components or subsystems;
detecting patterns in the obtained data on the vehicle;
analyzing, using a processor on the vehicle, the detected patterns to create a prediction of an impending failure of one of the components or subsystems before the predicted failure occurs; and
informing the user, owner, dealer or manufacturer of the vehicle about the predicted failure before the predicted failure occurs to enable corrective action to be taken before the predicted failure occurs,
whereby a breakdown of the vehicle that might occur if the predicted failure of the component were to occur is thereby avoided.
2. The method of claim 1 , further comprising providing a trained pattern recognition algorithm to detect the patterns in the obtained data and analyze the detected patterns.
3. The method of claim 2 , further comprising using vehicle model-specific data to train the pattern recognition algorithm.
4. The method of claim 1 , further comprising communicating the predicted failure to the dealer or manufacturer at a location remote from the vehicle.
5. The method of claim 1 , further comprising arranging a communications unit on the vehicle to inform the dealer or manufacturer of the vehicle about the predicted failure.
6. The method of claim 1 , further comprising:
coupling the sensors to the processor on the vehicle; and
constructing the processor to detecting the patterns in the obtained data and analyze the detected patterns to create a prediction of an impending failure of one of the components or subsystems such that the processor converts input from the sensors into an output constituting a signal about the condition of the components or subsystems.
7. The method of claim 1 , wherein the step of informing the user, owner, dealer or manufacturer of the vehicle about the predicted failure comprises notifying the user of the vehicle.
8. The method of claim 7 , wherein notification to the user is provided via a display on the vehicle visible to the user.
9. The method of claim 1 , wherein the step of informing the user, owner, dealer or manufacturer of the vehicle about the predicted failure comprises notifying the owner of the vehicle.
10. The method of claim 9 , wherein the notification to the owner is provided via a telecommunications system on the vehicle.
11. The method of claim 1 , wherein the step of informing the user, owner, dealer or manufacturer of the vehicle about the predicted failure comprises notifying the dealer.
12. The method of claim 11 , wherein the notification to the dealer is provided via a telecommunications system on the vehicle.
13. The method of claim 1 , wherein the step of informing the user, owner, dealer or manufacturer of the vehicle about the predicted failure comprises notifying the manufacturer.
14. The method of claim 13 , wherein the notification to the manufacturer is provided via a telecommunications system on the vehicle.
15. The method of claim 1 , further comprising notifying a repair facility about the predicted failure.
16. The method of claim 15 , wherein the notification to the repair facility is provided via a telecommunications system on the vehicle.
17. The method of claim 1 , wherein the vehicle is a motor vehicle whereby one of the plurality of components an engine.
18. The method of claim 1 , wherein the patterns in the obtained data on the vehicle are detected using a processor.
