Zusammenfassung:The invention provides a method and device for controlling a torque of an electric automobile. The method and device for controlling the torque of the electric automobile aim to solve the problem that in the relevant technology, torque control is not accurate enough when the electric automobile is in the cruise control state. The method comprises the steps that a proportional parameter and an integral parameter of a proportional integral controller are determined according to a current vehicle speed of the electric vehicle and a speed difference value between the current vehicle speed and a target vehicle speed when the electric automobile is in the cruise control state; the speed difference value is input into the proportional integral controller to obtain the compensation torque; and an output torque when the electric automobile is in the cruise control state is determined according to the compensation torque. 本公开提供种控制电动汽车转矩的方法和装置,以解决相关技术中电动汽车在定速巡航状态下转矩控制不够精确的问题。所述方法包括:根据所述电动汽车当前车速,以及所述当前车速和所述电动汽车在定速巡航状态下的目
