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.
