“…The control of brake torques at each wheel using brake-based ESP 16,17 and DYC 18,19 have proved to be very effective in achieving better handling and stability. With the advances in technology, the use of electronic differentials 20 and torque-vectoring systems 21 can also differentially distribute the available drive torque from the engine to all four wheels for better acceleration and control of the lateral dynamics. 22 In addition, there have been research efforts to integrate steering and braking to take advantage of both the systems.…”

Autonomous vehicles have attracted more attention in recent years as vehicle applications are evolving to a more intelligent and autonomous stage. This paper presents the development of a collision avoidance system for an autonomous vehicle application which consists of a motion planner and model-predictive-control-based active vehicle steering and active wheel torque control. A motion planner, based on polynomial parameterization, determines a collision-free trajectory when a vehicle collision with obstacles is likely to happen. Then an MPC-based control system controls the front steering and individual wheel torques to track the desired collision-free reference trajectory. The proposed system is evaluated through simulation, using an eight-degrees-of-freedom vehicle model with a ‘magic formula’ tire model, active front steering, and active wheel torque distribution systems. The simulation results show that it effectively performs collision avoidance maneuvers.

“…Similarly, electronic differentials [13,14] and torque vectoring systems [15,16] can be used to distribute differentially the available drive torque from the engine to all four wheels for better acceleration and control of lateral dynamics [17,18]. Such torque distribution systems are less intrusive and achieve smoother control of lateral dynamics without excessive loss of forward velocity.…”

Wheel torque control is an effective means of improving vehicle handling and stability. Brake-based electronic stability programs which intervene in extreme situations to regulate vehicle behaviour are the most common form of wheel torque control. With the advent of advanced driveline technologies, wheel torque control can also be achieved by the differential distribution of available drive torque to all four wheels. Similarly, in combined cornering and braking manoeuvres, the applied brake input can be differentially distributed to regulate vehicle handling. This paper proposes an integrated scheme for wheel torque control that combines differential drive or brake torque distribution with the emergency braking control to regulate the vehicle yaw rate and side-slip angle. A wheel torque controller was developed using a non-linear predictive control theory, an eight-degrees-of-freedom vehicle model, and non-linear tyre models. The simulated vehicle responses show improved vehiclehandling performance.
