Abstract

In order to allow the cyclist to keep the state of the batteries under control during use of a bicycle equipped with an on-board electronic apparatus or during the recharging of the batteries, data is displayed to the cyclist relative to the batteries on the display device of the on-board electronic apparatus.

Claims

1. Electronic system for a bicycle comprising an on-board electronic apparatus, comprising a display device, a battery power supply unit, and electronics for obtaining at least one datum relative to the battery power supply unit and for displaying the at least one datum on the display device, and a battery-charger, wherein the battery-charger has no display unit.

2. The system according to claim 1, wherein the electronics comprises a plurality of components connected in a network for data communication.

3. The system according to claim 2, wherein the components communicate through a half duplex asynchronous serial communication protocol through a data line.

4. The system according to claim 1, wherein the battery power supply unit is of the rechargeable type.

5. The system according to claim 1, wherein the battery-charger is removably associable with the on-board electronic apparatus.

6. The system according to claim 1 wherein the at least one datum is a remaining charge.

7. The system according to claim 1 wherein the at least one datum is a distance remaining related to current battery supply unit usage.

8. The system according to claim 1 wherein the at least one datum is a time duration remaining related to current battery supply unit usage.

9. The system according to claim 1 wherein the at least one datum related to the battery supply unit can be displayed on the display unit during operation of the cycle.

10. The system according to claim 9, wherein displaying the at least one datum related to the battery supply unit is optional, and the displaying of the datum is controlled by a user.

11. Method for managing an on-board electronic apparatus for a bicycle comprising a display device and a battery power supply unit, comprising the steps of obtaining at least one datum relative to the battery power supply unit, and displaying the at least one datum on the display device, wherein the step of obtaining at least one datum relative to the battery power supply unit is carried out at predetermined recurrence when the on-board electronic apparatus is in an active condition.

12. The method according to claim 11, wherein the at least one datum relative to the battery power supply unit is selected from the group consisting of a temperature, a voltage at the terminals, a remaining charge, an alarm state, a recharge state and a remaining autonomy of the battery power supply unit.

13. The method according to claim 11, further comprising the step of displaying information other than the at least one datum relative to the battery power supply unit on the display device.

14. The method according to claim 13, further comprising a step of manually selecting the information to be displayed.

15. The method according to claim 14, wherein the at least one datum relative to the battery power supply unit comprises an alarm state or a recharge state of the battery power supply unit, and wherein the method comprises a step of forcing the display of the at least one datum relative to the battery power supply unit.

16. The method according to claim 11, comprising the steps of:

obtaining a charge consumption of the battery power supply unit per unit traveled distance,

detecting a remaining charge of the battery power supply unit,

calculating an available remaining distance as a ratio between the remaining charge and the charge consumption per unit traveled distance, and

displaying the available remaining distance.

17. The method according to claim 16, wherein the step of obtaining a charge consumption per unit traveled distance comprises the steps of:

obtaining a consumed charge,

obtaining a traveled distance,

calculating the charge consumption per unit traveled distance as a ratio between the consumed charge and the traveled distance.

18. The method according to claim 16, further comprising the steps of:

obtaining an average speed,

calculating an available remaining time as a ratio between the available remaining distance and the average speed, and

displaying the available remaining time.

19. The method according to claim 18, further comprising the steps of:

detecting a travel time,

calculating remaining days as a ratio between the available remaining time and the travel time, and

displaying the remaining days.

20. The method according to claim 18, wherein the charge consumption per unit traveled distance, average speed and/or travel time are daily averages.

21. The method according to claim 18, wherein the charge consumption per unit traveled distance, average speed and/or travel time are values averaged over a predetermined number of days.

22. The method according to claim 11, further comprising the step of recharging the battery supply unit.

23. Method for managing an on-board electronic apparatus for a bicycle comprising a display device and a battery power supply unit, comprising the steps of obtaining at least one datum relative to the battery power supply unit, displaying the at least one datum on the display device, and recharging the battery power supply unit, wherein the step of obtaining at least one datum is carried out at least in part during the recharging step.

24. Method for managing an on-board electronic apparatus for a bicycle comprising a display device and a battery power supply unit, comprising the steps of obtaining at least one datum relative to the battery power supply unit, and displaying the at least one datum on the display device, wherein the step of obtaining at least one datum relative to the battery power supply unit is carried out at predetermined recurrence when the on-board electronic apparatus is in a stand-by condition.
