Abstract
The present disclosure relates to a real-time control method for an additional yaw moment of a distributed drive electric vehicle, including the following steps: acquiring and inputting a real-time motion state of the distributed drive electric vehicle into a vehicle dynamics model, using a yaw rate and a sideslip angle of the distributed drive electric vehicle as tracking targets to suppress actuation energy, and performing optimization calculation on an additional yaw moment to acquire an amount of the additional yaw moment distributed for each tire; and in the optimization calculation process, a linear expression of the sideslip angle with respect to the additional yaw moment and a linear expression of the yaw rate with respect to the additional yaw moment are constructed, so as to perform search calculation on the additional yaw moment.
