ELECTRICALLY ASSISTED VEHICLE |
摘要 |
An electrically assisted vehicle includes a vehicle main body having a driving wheel, a human drive system having a driving force applying part to which a human driving force for driving the driving wheel is applied and a torque detecting part for detecting the human driving force applied to the driving force applying part, and an electric drive system having a motor, a control part for controlling the motor and a battery for power supply, wherein the motor has an electric driving force characteristic such that it outputs the electric driving force only at speeds lower than a predetermined speed, and the control part of the electric drive system controls the motor with a predetermined ratio on the basis of detection results from the torque detecting part of the human drive system; thereby executing power assistance control while maintaining the assist ratio to be less than a predetermined value without providing a speed sensor for carrying out control based on the speed.
