Description

technical field

[0001] The invention belongs to the technical field of pure electric vehicles, and in particular relates to a method for controlling driving torque of pure electric vehicles. Background technique

[0002] Since the pure electric vehicle uses the electric motor as the power source, it has strong acceleration performance, and the acceleration time from 100 kilometers is generally within 10s, or even within 5s. When the controller software data overflows, unexpected driving torque may be generated. It leads to a large unexpected acceleration in a short period of time, resulting in a high risk of vehicle driving, which in turn poses a great threat to the driver's safety. Contents of the invention

[0003] The purpose of the present invention is to provide a method for controlling the driving torque of a pure electric vehicle, so as to limit the driving torque and reduce the safety threat to the driver.

[0004] The control method of the driving torque of the p...
