Abstract

A feedback and training system for use in a vehicle the vehicle comprising or connected to one or more sensors enabled to measure one or more physical parameters associated with the vehicle; the system comprising a database, configured to receive and store data from the sensors, a processor enabled to calculate at least one performance factor based at least partly on the current physical parameters measured from the one or more sensors, a display configured to display to a driver representations of one or more of the performance factors, wherein the calculation of a performance factor, or the timing of or the prominence given to the display of the representation of a performance factor, is dependent on historic sensor data stored in the database received previously from the sensors.

Claims

1. A feedback and training system for use in a vehicle:

the vehicle comprising or connected to one or more sensors enabled to measure one or more physical parameters associated with the vehicle;

the system comprising;

a database, configured to receive and store data from the one or more sensors,

a processor enabled to calculate at least one performance factor based at least partly on the current physical parameters measured from the one or more sensors, and

a display configured to display to a driver representations of one or more of the performance factors,

wherein the prominence given to the display of the representation of a performance factor is dependent on historic sensor data stored in the database received previously from the sensors.

2. The system of claim 1

wherein the calculation of the performance factor, or a timing of the display of the representation, is dependent on historic sensor data stored in the database received previously from the sensors.

3. The system of claim 1 wherein at least one performance factor is primarily or wholly indicative of current vehicle performance.

4. The system of claim 1 wherein the processor determines the identity of the driver using the vehicle/system and the system is configured to store at least some of the sensor data in the database in a suitable location or with suitable metadata that it could be identified as being produced by a particular driver.

5. The system of claim 1 wherein the processor is enabled to calculate a plurality of different performance factors based at least partly on the current physical parameters measured from the one or more sensors,

the display configured to display to a driver representations of a plurality of the performance factors,

the processor configured to weight the relevance of a plurality of the performance factors based on the historic sensor data;

and

wherein the prominence given to the display of the representation of a plurality of performance factors on the display is dependent on the relevance weighting of the plurality of performance factors.

6. The system of claim 5,

wherein the weighting of the relevance of a plurality of the performance factors comprises weighting the relevance to the currently identified driver, based on historic sensor data stored in the database identifiable as having been produced by the currently identified driver, and

wherein the prominence given to the display of the representation of a plurality of performance factors on the display, such as the determination of which performance factor representation should be displayed or displayed most prominently, is dependent on the determined weighted relevance to the currently identified driver.

7. The system of claim 1 wherein the prominence given to the display of the representation of a performance fact, or the calculation of a performance factor, or a timing of display of the performance factor, is dependent on prior journey historic sensor data stored in the database received from the sensors during previous journeys to the current measured physical parameters.

9. The system of claim 1 wherein the calculation of one or more performance factors uses one or more algorithms derived from data from a different vehicle to that connected to or comprising the sensors, with the current physical parameters measured from the one or more sensors being used as inputs into the algorithms.

10. The system of claim 1 wherein the calculation of one or more performance factors uses one or more algorithms derived from theoretical considerations, with the current physical parameters measured from the one or more sensors being used as inputs into the algorithms, based at least partly on the current physical parameters measured from the one or more sensors.

11. The system of claim 1 wherein the calculation of one or more performance factors uses one or more algorithms, and wherein at least one of the algorithms is modified based on the historic sensor data stored in the database, not the historic data used as inputs.

12. The system of claim 10 wherein the calculation of a performance factor, or the timing of or the prominence given to the display of the representation of a performance factor, is dependent on historic sensor data relating to the currently determined driver stored in the database received previously from the sensors and identifiable as having been produced by the currently identified driver.

13. The system of claim 10 wherein calculation of a performance factor, is dependent on historic sensor data stored in the database received previously from the sensors and identifiable as being produced by more than one determined driver.

14. The system of claim 1 wherein the processor is further enabled to calculate or select driver training data comprising instructions on how to use displays of performance factors or optimise the value of performance factors, based on the measured performance factor and a predetermined performance factor;

the system configured to display the calculated or selected training data on the display.

15. The system according to claim 14 wherein the database comprises a plurality of training data sets and the processor is configured to determine the relevancy of a plurality of different training data in the database, the relevance to the currently identified driver, and display the most relevant training data, wherein the relevancy is determined by one or more of:

a current performance factor, historical sensor data produced by the currently identified driver, and occurrence of previous training data being displayed to the currently identified user.

19. The system of claim 1 wherein the physical parameters measured by the sensors are one or more of:

speed, acceleration, fuel level/use, engine revolutions, gear changes, throttle level, use of brakes, location information and distance behind the nearest different vehicle.

20. The system of claim 1 wherein the sensors comprise one or more of:

a speedometer, an accelerometer, a tachometer, a front facing camera, and a gps unit.

22. The system of claim 1 wherein the performance factors determined by the processor are one or more of:

fuel consumption, desirable top speed, desirable gear, rate of acceleration, rate of deceleration, distance from vehicle ahead.

23. The system of claim 1 wherein at least part of the database and/or the processor are stored outside of the vehicle and the system preferably comprises wireless communication means configured to send data from the sensors to the database.
