Verfahren zum Betrieb eines muskelkraftbetriebenen Fahrzeugs und Fahrzeug
摘要
<p>The present invention relates to a method for powering a muscle-operated vehicle and to a vehicle of said type itself wherein a muscle-operated driving system and an auxiliary electric power driving system is provided in conjuncation with a control means for controlling the output of the said electrical power driving system in response to variations of a pedal depressing force of the muscle-operated driving system. According to the present invention the ratio between the electric motor drive force and the pedal force of said two systems is said to be variable in response to vehicle speed assuring appropriate power assistance, specifically under high speed vehicle operating conditions for which it is preferred to decrease the power assistance. <IMAGE></p>
