The invention provides a torque determining method and device and an electric vehicle to solve the problems that the torque output by an electric vehicle fails to satisfy the current driving demand since an existing torque management method only calculates a demand torque based on a gear signal or the like without considering a currently-turned-on application function of the vehicle. The torque determining method of the invention includes the steps of determining a first target demand torque according to a demand torque corresponding to a current operating parameter; determining whether an electric vehicle turns on a preset application function; and if the electric vehicle turns on the preset application function, determining a final demand torque of the electric vehicle according to a second target demand torque corresponding to the preset application function, and otherwise, determining a final demand torque of the electric vehicle according to the first target demand torque. According to the invention, the final demand torque is enabled to satisfy the current preset application function and the purpose of meeting the current satisfying demand is achieved.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method and device for determining torque and an electric vehicle. Background technique [0002] At present, when managing the torque of electric vehicles, the driver's demand torque is only calculated based on the gear signal, acceleration signal, braking signal, and motor and battery signals, without considering the current application functions of the vehicle, such as enabling anti-slope , constant speed cruise, drive anti-skid and other functions make it difficult for the torque output by electric vehicles to meet the current driving needs. Contents of the invention [0003] The purpose of the present invention is to provide a torque determination method, device and electric vehicle to solve the problem that the existing torque management method only calculates the required torque according to the gear signal and does not consider the application function current...
