Abstract:
(EN) Provided are a method and device for controlling the output torque of an electric motor, and an automobile, the method for controlling the output torque of an electric motor comprising: determining a driving mode of an automobile (1); acquiring the degree to which an accelerator pedal is open and the rotation speed of an electric motor when the driving mode of the automobile is a single-pedal driving mode (2); determining an initial output torque of the electric motor according to the degree to which the accelerator pedal is open and the rotation speed of the electric motor (3); and performing torque value-limiting processing on the initial output torque of the electric motor to obtain a torque after the torque value-limiting processing, and outputting same (4).
(FR) L'invention concerne un procédé et un dispositif de commande du couple de sortie d'un moteur électrique, et une automobile, le procédé de commande du couple de sortie d'un moteur électrique comprenant les étapes suivantes : la détermination d'un mode de conduite d'une automobile (1) ; l'acquisition du degré selon lequel une pédale d'accélérateur est ouverte et de la vitesse de rotation d'un moteur électrique lorsque le mode de conduite de l'automobile est un mode de conduite à pédale unique (2) ; la détermination d'un couple de sortie initial du moteur électrique en fonction du degré selon lequel la pédale d'accélérateur est ouverte et de la vitesse de rotation du moteur électrique (3) ; et la mise en œuvre d'un traitement de limitation de valeur de couple sur le couple de sortie initial du moteur électrique pour obtenir un couple après le traitement de limitation de valeur de couple, et la délivrance en sortie de celui-ci (4).
(ZH) 一种电机的输出扭矩控制方法、装置及汽车,电机的输出扭矩控制方法包括:确定汽车的驾驶模式(1);获取汽车的驾驶模式为单踏板驾驶模式时的油门踏板开度和电机转速(2);根据油门踏板开度和电机转速,确定电机的初始输出扭矩(3);对电机的初始输出扭矩进行扭矩限值处理,获得进行扭矩限值处理后的扭矩,并输出(4)。
