Publication number: 20140196968Abstract: An electrically assisted street scooter includes a handlebar, a deck, front and back wheels, a battery pack integral with the deck, an electrical motor for driving at least one of the wheels, and a drive circuit for controlling electrical supply to the electrical motor from the battery pack. The drive circuit includes a switch for setting the drive circuit in a low power-mode where the electrical motor is not powered when the switch is off, or for setting the drive circuit in a drive mode where the electrical motor can be powered when the switch is on. An auto-power on circuit automatically switches the switch on when a user pushes the street scooter. An auto-power off circuit automatically switches the switch off when the scooter is not used during a predetermined duration. The level of electrical assistance is determined based on the peak value after each leg push.Type: ApplicationFiled: May 24, 2012Publication date: July 17, 2014Applicant: MICRO-BEAM SAInventors: Thierry Bieler, Laurent Cardoletti, Christian Fleury, Christian Koechli, Simon Tinguely

Patent number: 7443128Abstract: An electronic device is provided for controlling a motor having three phases driven by a motor driver. In one implementation, the electronic device includes a detection means and a control circuit. The detection means includes three high-gain differential amplifiers and three A/D converters. The detection means detects back EMF voltages induced by the rotation of the motor and applies corresponding signals to the control circuit. The control circuit computes and filters the position and/or the speed of the motor and then delivers the filtered values of the computed rotor position and/or speed to control the motor driver. The motor may thus be controlled even at near-zero rotational speed.Type: GrantFiled: February 4, 2005Date of Patent: October 28, 2008Assignee: Micro-Beam S.A.Inventors: Thierry Bieler, Laurent Cardoletti, Christian Fleury, Christian Koechli
