Title: Electrically assisted bicycle and its control method
Inventor: TOSAKA SUSUMU
IPC: B62J6/00
Filed: 2003-04-08
Abstract: <P>PROBLEM TO BE SOLVED: To improve safety and comfort by obtaining a stable static condition using an assistant drive function at the time of stopping on an inclined face.  <P>SOLUTION: An inclination angle of a road on which a bicycle travels is calculated by using detection signals from an XY two-axis acceleration sensor 314. Steady torque for offsetting a downward direction generated to a bicycle stopping on the inclined face using a inclination angle detecting function is applied to an assist motor 51 so as to control the bicycle in a manner to easily stop. That is, when the road on which the bicycle stops is an inclined face such as a slope, tare weights of the bicycle and a driver act in the downward direction of the inclined face. Because the bicycle is naturally moved, such a need is caused that a user supports the bicycle by straddling legs, and brakes the bicycle. Torque is steadily applied in a direction for offsetting a downward direction by the tare weights of the bicycle and the driver on the inclined face so as to reduce a supporting force of the user, and improve the comfort of the user.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
