Dynamic steering response (DSR) is a vehicle safety and advanced power steering system that can counteract unstable or difficult steering that may be caused by external forces such as strong crosswinds or uneven roads by giving proper steering assistance from the steering gear.[1] DSR assists the driver by determining the correct steering ratio in a vehicle's power steering system to provide steering corrections to stabilize vehicles and increase safety. The system determines the steering ratio (the amount of turning of the steering wheel to the amount of turning of the vehicle’s wheels) based on factors such as current road conditions and vehicle speed. This system works by having an electric motor attached to the steering gear of a vehicle reducing or increasing the torque needed to steer based on the situation.[1] Thus, less physical input from the driver is required creating a more comfortable driving experience overall.[2]
DSR was first implemented in SEAT’s 2002 León Cupra R.[3] But according to Acumen Research and Consulting, as of February 04, 2020, among the companies that have manufactured DSR systems, “the leading competitors are BMW, Ford Motor, Volvo, ZF-TRW, AUDI, Bosch, Denso Corporation, Danfoss, and Knorr-Bremse”.[4] But DSR’s implementation is not limited to commercial cars as buses and industrial vehicles have taken advantage of the technology as well.
