Abstract

A method of estimating energy recovered by a vehicle including a regenerative braking mechanism, with at least two energy recovery systems generating at least two respective setpoint values and configured for the regenerative braking mechanism, the method including receiving one of the setpoint values and calculating an energy value on the basis of the setpoint value received.

Claims

1-11. -11. (canceled)

12. A method for estimating energy recovered by a vehicle including a regenerative braking means and at least two energy recovery systems generating at least two respective setpoint values configured for the regenerative braking means, the method comprising:

receiving one of the setpoint values; and

calculating an energy value from the received setpoint value.

16. The method as claimed in claim 12, further comprising, for the received setpoint value:

multiplication by a speed value of the vehicle to obtain a power value;

temporal integration of the obtained power value to obtain an energy value.

20. A device for estimating energy recovered by a vehicle including a regenerative braking means and at least two energy recovery systems generating at least two respective setpoint values configured for the regenerative braking means, the device comprising:

means for receiving one of the setpoint values;

means for calculating an energy value on the basis of the received setpoint value.

21. The device as claimed in claim 20, further comprising at least one buffer memory configured to store the energy value received from the calculation means and a braked distance value associated with the energy value.

22. A vehicle comprising the regenerative braking means, the at least two energy recovery systems, and the energy estimation device as claimed in claim 20.
