Allocation-based control for four-wheel independently driven and braked electric vehicle considering actuators´ dynamic characteristics

This paper proposes an allocation-based control method for four-wheel independently driven and braked electric vehicle by taking into consideration of actuators dynamic characteristics. The dynamic characteristics of both driving and braking actuators are modeled as physical constraints in order to form a constrained optimization problem. A slacking method is introduced and analyzed in determining the body force distribution through the optimization-based control allocation. The simulation is conducted and the results show that the proposed method works as expected and is valid and effective.
