MOBILITY VEHICLE AND POWER-ASSISTING SYSTEM
First Claim
1. A power-assisting system providing power to a personal mobility vehicle, the power-assisting system comprising:
- at least one actuation unit comprising a motor and a power amplifier geared with the motor;
a sensing unit comprising a rotating speed sensor, a multi-axis accelerometer and a multi-axis gyroscope and configured for sensing acceleration of the personal mobility vehicle, an angular velocity of the personal mobility vehicle and a rotating speed of the motor; and
a signal processing device unit connected to the actuation unit and the sensing unit to process signals of the sensing unit, so as for the actuation unit to generate damping compensation, inertia compensation, and gravity compensation in accordance with the processed signals.

Abstract
A mobility vehicle includes a personal mobility vehicle having at least one wheel body and a power-assisting system. The power-assisting system includes an actuation unit, a sensing unit and a signal processing unit. The actuation unit has a motor and a power amplifier geared with the motor. The sensing unit includes a motor rotation speed sensor, a multi-axis accelerometer and a multi-axis gyroscope, so as to sense the velocity, acceleration and the absolute angular velocity of the mobility vehicle in motion in real time. The signal processing unit is connected to the actuation unit and the sensing unit, so as to process the signals of the sensing unit. Then, the actuation unit performs inertia compensation, damping compensation and gravity compensation to the mobility vehicle through a dynamic signal-conditioning algorithm. When the mobility vehicle is actuated by human-power, the power-assisting system assists the power automatically to save human labor.
