electronic power steering
How does EPS work in a car?
EPS uses an electric motor to assist the driver of a vehicle, unlike traditional systems that act on hydraulic pressure provided via a pump driven by the vehicle’s engine. This pump is constantly running, whether the steering wheel is being turned or not.
What causes electric power steering failure?
Since your power steering pump is a simple machine, the most common cause of failure for a power steering pump is the bearing going bad. When they get very worn, they can cause leakage around the pump shaft behind the pulley and even allow the pulley to wobble.
Is it safe to drive without EPS?
The new EPS with fail-operational function is an essential technology to safely realize automated driving.” As with the Denso system, if the driver is still in the loop they can safely steer the vehicle without the sudden increase in steering force usually assosciated with an EPS failure.
