Abstract

In a power assist type vehicle having a manual driving system and a power assist driving system in parallel to drive wheels by the man power added to the manual driving system and the assist power according to the man power supply, the vehicle comprises a pedal switch as a man power detecting means for detecting the man power added to the manual driving system, a vehicle sensor 18 or rotating speed sensor as a traveling speed detecting means for detecting the traveling speed of the vehicle, and a controller 22 as an assist power control means for leaving the assist power after the stop of man power supply is detected by the man power detecting means, and changing the remaining time of the assist power according to the traveling speed detected by the traveling speed detecting means.

Description

Technical field [0001] The present invention relates to auxiliary power-driven vehicles such as bicycles or wheelchairs, which have wheels suitable for driving with human power acting on the human power drive system and auxiliary power from the auxiliary power drive system. Background technique [0002] Traditional motor-assisted vehicles, such as motor-assisted bicycles or motor-assisted wheelchairs, have been put into practical use. In this type of vehicle, the current equivalent to the human power acting on the human drive system is supplied from the battery to the motor, thereby reducing The combined force of the driving force (assistance force) of the electric motor and the manpower is transmitted to the wheels. [0003] The above-mentioned conventional auxiliary power-driven vehicle includes a control unit that performs calculations based on the amount of manpower to control the current value delivered to the motor. This vehicle is configured to add auxiliary power proporti...
