Wheel Slip Balance Based Anti-Slip Regulation on Dissymmetric Road Grip

Anti-Slip regulation system (ASR) as the name suggests, prevents excessive wheel spin by limiting wheel slip on the spinning wheel using brake torque or engine torque intervention when starting off and accelerating, particularly on a slippery road surface. These kinds of circumstances can overtax the driver not only causing them to react inappropriately but also causing the vehicle to become unstable. (ASR) tackles these problems, providing the vehicle remains within the physical limits. This paper presents an inter-axle anti-slip regulation logic for vehicle stability in the midst of dissymmetric road grip conditions. It employs the inter-axle wheel slip balance control strategy, to increase driving stability and improve traction with respect to the driver's torque request. The proposed method is assessed and validated by simulation in AMESim. Results demonstrate the effectiveness of the proposed method in terms of vehicle stability and steer ability through the regulation of drive torque at each driven wheel based on the inter- axle slip balance target. In addition to this safety relevant-task of ensuring stability and steering ability of the vehicle in the acceleration phase, ASR improves traction by helping find levels of wheel slip not easily accessible.
