- Summary:
- A hydraulic-assisted power steering system on a vehicle has asteering pump which is directly driven from the enginecontinuously. In real world, the assistance from the steering pumpis useful only while maneuvering. During a typical highway drive,assistance from this power steering pump remains unused formajority (76%) of the time; although the continuously rotatingpower steering pump keeps consuming energy from the engine. Anelectronic controller has been provided for the electro-magneticpairing device of the power steering pump in order to provideassistance for steering based on driver demand only. Theelectromagnetic pairing device integrated on the steering pump canbe made to engage/disengage based on the driver demand through theelectronic controller. The benefit with such a system includesreduced energy consumption from the engine (lower CO₂ emission)& consequent improvement in fuel economy (4 to 6% improvementin highway fuel efficiency) coupled with on-demand power assistanceto steering
