Abstract

A monitoring apparatus provides vehicle telematics data. The monitoring apparatus includes a sensor for sensing vehicle and engine motion induced vibration in part of a vehicle and for generating vibration associated data. The sensor is coupled to part of the vehicle. Engine motion induced vibration associated data is processed to extract a characteristic of the vehicle or the engine.

Claims

1. A monitoring apparatus for providing vehicle related data, the apparatus comprising:

at least one sensor for sensing vehicle related motion and for generating associated vehicle related motion data;

a processor for processing said vehicle motion associated data to generate processed data representing at least one characteristic of said vehicle; and

a transceiver for communicating said processed data representing at least one characteristic of said vehicle to a communication device for use in compiling telematics data for said vehicle;

wherein said processor is configured to identify at least one vehicle related event from said vehicle related motion data; and

wherein said processor is configured to perform a preliminary analysis on acquired data, prior to storing any acquired data for subsequent transmission, and to determine, based on the analysis whether at least one specific event has occurred and based on a determination that the at least one specific event has occurred to determine that the acquired data should be stored.

2. The monitoring apparatus according to claim 1, wherein said processor is configured to determine an orientation of at least one accelerometer axis, relative to at least one axis of the vehicle, before generating processed data based on acceleration thresholds that are respectively different in different directions.

3. The monitoring apparatus according to claim 2, wherein said processor is adapted to maintain said orientation of said vehicle related motion data to the longitudinal and lateral axes for at least some future occasions when, in use, the vehicle begins to move after being stationary.

4. The monitoring apparatus according to claim 1, wherein said at least one sensor is configured to sense vehicle related motion in a plurality of different dimensions and to provide associated vehicle related motion data for said plurality of different dimensions.

5. The monitoring apparatus according to claim 1, wherein said processor is adapted to derive an orientation of said vehicle related motion data relative to a longitudinal axis representing vehicle motion in a forward/reverse direction and to a lateral axis representing vehicle motion in a lateral direction.

6. The monitoring apparatus according to claim 1, wherein said processor is adapted to derive an orientation of said vehicle related motion based on a gravitational force.

7. The monitoring apparatus according to claim 1, wherein said at least one sensor is configured to sense vehicle and/or engine motion induced vibration in part of a vehicle to which the at least one sensor is coupled and to generate corresponding vibration associated data, wherein said processor is configured to process said vibration associated data to generate processed data representing at least one characteristic of said vehicle and/or engine.

8. The monitoring apparatus according to claim 7, wherein said processor is adapted to generate said processed data based on a frequency analysis of said vibration.

9. The monitoring apparatus according to claim 7, wherein the apparatus, by virtue of having a weight of less than 100 g, is sufficiently lightweight to allow the at least one sensor to sense said vehicle induced vibration in said part of said vehicle with sufficient sensitivity for the processor to detect, from said vehicle motion induced vibration, at least one event affecting said vehicle that occurs while the vehicle is stationary with the engine off.

10. The monitoring apparatus according to claim 7, wherein said processor is adapted to process said vibration associated data to provide processed data representing at least one characteristic of said vehicle or engine comprising at least one characteristic from the following list of characteristics:

engine revolutions per minute (RPM), wheel RPM, currently engaged gear, idle frequency, stroke cycle, number of cylinders, vehicle speed, engine type and/or vehicle type.

11. The monitoring apparatus according to claim 7, wherein said processor is adapted to identify said at least one vehicle related event based on said vibration associated data.

12. The monitoring apparatus according to claim 1, wherein said processor is adapted to process said vehicle related motion data to provide processed data representing at least one event affecting said vehicle, the at least one event comprising at least one event from the following list of events:

an acceleration event, an impact event while the vehicle is stationary and the engine is off, a motion event while the vehicle is stationary and the engine is on, a door opening or closing event, and an impact while moving event; and

wherein said transceiver is adapted to communicate said processed data representing at least one event affecting said vehicle to the communication device for use in compiling telematics data for said vehicle.

13. A method of monitoring vehicle telematics data using the monitoring apparatus of claim 1, the method comprising:

sensing, at the sensor of the monitoring apparatus, vehicle motion associated data to generate processed data representing at least one characteristic of said vehicle;

processing, at the processor of the monitoring apparatus, said vehicle related motion data to generate processed data representing at least one characteristic of said vehicle; and

communicating, using the transceiver of the monitoring apparatus, said processed data representing at least one characteristic of said vehicle or engine to a communication device for use in compiling telematics data for said vehicle.

14. A computer program product comprising computer implementable instructions for putting the method of claim 13 into effect when executed on a programmable device.
