This paper presents a model for analysing the handling dynamics and lateral stability control of a vehicle featuring a hydrostatic independent wheel drive system for integrating energy efficiency with safety. The stability control system determines the necessary corrective yaw moment and achieves correction of oversteer or understeer via a controlled differential actuation of the wheel-end hydraulic pump/motors. During aggressive handling manoeuvres, the motors can be operated as pumps for re-generating the vehicle's kinetic energy into on-board hydraulic accumulators. This system has the distinct benefit of avoiding excessive activation of the friction brakes as is common in current stability control technology.
