A Matter of Torque Electric power steering system
نویسنده
چکیده
EPS in modern cars can significantly reduce fuel consumption when compared to cars using hydraulic solutions. Industry studies have shown that EPS can save up to 85 percent of the energy normally needed to steer a vehicle with conventional hydraulic systems. The result is fuel consumption reductions of up to 0.3 liters per 100 kilometers driven. EPS is so efficient because the system is only activated when steering support is really needed. As a result, a permanent engine load is not required. EPS systems also can help ensure safer driving. The steering torque is adapted to the vehicle’s speed and optimized for different driving situations. For example, during low-speed driving maneuvers, such as parking, EPS provides a higher level of assistance than it does at higher speeds, when electronic power assist is gradually reduced to enable more direct steering and better feedback from the road.
