Abstract:

Turning Circle Diameter (TCD) is a critical parameter in vehicle manoeuvrability, particularly in urban environments where tight turns and compact parking spaces are prevalent. Traditional front-wheel steering systems limit the potential for reducing TCD due to geometric and packaging constraints. This paper investigates the implementation of rear-wheel steering (RWS) as a means to reduce TCD. Based on simulation and theoretical analysis, two RWS configurations — 5° and 7° rear steer angles are evaluated. Results show an approximate 8% and 12% reduction in TCD, respectively. However, mechanical constraints such as wheel envelope clearance, interference with suspension components, and vehicle loading conditions must be addressed to ensure feasibility. The study concludes that RWS can be a highly effective solution for improving low-speed manoeuvrability when integrated carefully with physical constraints.
