Title (EN) ELECTRIC BICYCLE AND SHIFT ASSIST DEVICE AND SHIFT CONTROL METHOD THEREOF
(FR) VÉLO ÉLECTRIQUE ET DISPOSITIF D'AIDE AU CHANGEMENT DE VITESSE ET PROCÉDÉ DE COMMANDE DE CHANGEMENT DE VITESSE CORRESPONDANT
(ZH) 电动自行车及其变速辅助装置和变速控制方法
Abstract:
(EN) A shift assist device for an electric bicycle having a built-in motor comprises: a central shaft rotation direction detection means (3) capable of detecting a reverse rotation signal of a central shaft (2) of a built-in motor (1), and outputting outwardly the reverse rotation signal; a motor control means (4) connected to the central shaft rotation direction detection means (3) and the built-in motor (1), the motor control means (4) receiving the reverse rotation signal outputted by the central shaft rotation direction detection means (3), and the motor control means (4) controlling a driving current of the built-in motor (1) to be chopped or cut off after receiving the reverse rotation signal. Also disclosed are an electric bicycle having the shift assist device and a shift control method of an electric bicycle. In the invention, tension acting upon a transmission chain is reduced, thereby ensuring a smooth subsequent gear shift operation, and improving comfort of riding an electric bicycle.
(FR) L'invention concerne un dispositif d'aide au changement de vitesse pour un vélo électrique comprenant un moteur intégré comprenant : un moyen de détection de direction de rotation d'arbre central (3) capable de détecter un signal de rotation inverse d'un arbre central (2) d'un moteur intégré (1) et d'émettre vers l'extérieur le signal de rotation inverse; un moyen de commande de moteur (4) raccordé au moyen de détection de direction de rotation d'arbre central (3) et au moteur intégré (1), le moyen de commande de moteur (4) recevant le signal de rotation inverse émis par le moyen de détection de direction de rotation d'arbre central (3), et le moyen de commande de moteur (4) commandant un courant d'entraînement du moteur intégré (1) devant être interrompu ou coupé après la réception du signal de rotation inverse. L'invention concerne également un vélo électrique comprenant le dispositif d'aide au changement de vitesse et un procédé de commande de changement de vitesse d'un vélo électrique. Dans l'invention, la tension agissant sur une chaîne de transmission est réduite, ce qui permet d'assurer une opération de changement de vitesse ultérieure régulière et d'améliorer le confort de conduite d'un vélo électrique.
(ZH) 一种装载中置电机的电动自行车的变速辅助装置,包括:中轴转向检测部分(3),其能够检测所述中置电机(1)的中轴(2)的反转信号,并将该反转信号向外输出;电机控制部分(4),其与所述中轴转向检测部分(3)和所述中置电机(1)均相连,该电机控制部分(4)接收所述中轴转向检测部分(3)输出的所述反转信号,并且当该电机控制部分(4)接收到所述反转信号后,其控制所述中置电机(1)的驱动电流被削减或切断。还公开了一种具有该变速辅助装置的电动自行车及电动自行车的变速控制方法。通过减小传动链条所受到的张紧力,保证后续变速换挡动作顺畅进行,提升电动自行车骑行的舒适性。
