Energy management system for motor-assisted user-propelled vehicles
First Claim
1. An energy management system for a motor-assisted user-propelled vehicle comprising a motor mounted on said vehicle and capable of at least assisting in propelling said vehicle and a power supply capable of supplying energy to said motor, said system comprising:
- a user input for providing a desired value for each of at least one user control parameter related to said user;
a sensor for each said at least one user control parameter for obtaining an actual value of said user control parameter;
a sensor for at least one vehicle control parameter, for obtaining an actual value of said vehicle control parameter;
a value comparator forreceiving said desired value and said actual value of each said at least one user control parameter,receiving said actual value of said vehicle control parameter;
comparing said desired value and said actual value of each said at least one user control parameter to generate a comparison signal for each said at least one user control parameter;
a command generator for generating a motor command using said at least one comparison signal and said actual value of said vehicle control parameter, said command generator comprising a parameter comparator for receiving said comparison signal with said actual value of said vehicle control parameter and evaluating said comparison signal with said actual value of said vehicle control parameter to generate at least one of an indicator signal and said motor command using said evaluation; and
a motor controller for operating said motor, using said motor command, to assist in propelling said vehicle in a way to bring said actual value of each said at least one user control parameter closer to said desired value of each said at least one user control parameter dependent on said evaluation.

Abstract
An energy management system for a motor-assisted user-propelled vehicle comprising a motor capable of assisting in propelling the vehicle and a rechargeable power supply for supplying energy to the motor. The system comprises: a user input for providing a desired value for each of at least one control parameter related to the user; a sensor for each control parameter for obtaining an actual value of the control parameter; a value comparator for receiving the desired value and the actual value of each control parameter and comparing them to generate a comparison signal for each control parameter; a command generator for generating a motor command using at least one comparison signal; and a motor controller for operating the motor, using the motor command, either to assist in propelling the vehicle, or act to recharge the power supply, in a way to bring the actual value closer to the desired value.

22. A sensor for obtaining an actual value of cyclic user propulsion effort for propelling a motor-assisted user-propelled vehicle for which the cyclic user propulsion effort is done by cyclic impulses of force by a user, said sensor comprising:
-
a detector for detecting slight cyclic variations in a speed of said vehicle, said slight cyclic variations being caused by said cyclic impulses of force by the user, said detector being one of directly and indirectly connected to any rotating part of said user-propelled vehicle and generating a vehicle speed signal; and a differentiator for differentiating said vehicle speed signal to obtain a vehicle acceleration signal; wherein at least one slight cyclic variation of the acceleration signal due to the cyclic user propulsion efforts is used to deduct said actual value of proportional cyclic user propulsion effort.
