Patent ID: 7706935

Claim:
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 for receiving 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.
