—A large interest has recently been given to global chassis control. This requires a tire model adapted to control synthesis that can represent combined slip. In this paper, a new suitable tire model for vehicle coupled operations control is proposed. The existing models are either too simple to represent coupled behaviors or too complex to allow control synthesis. This new tire model takes benefits from both approaches, as it is linear with varying parameters. Simulations of coupled operations proved the model accuracy in the tire stable range and its promising potential for global chassis control synthesis.
