Questions this course answers

What does power steering add to the mechanical steering path?

Hydraulic pressure or an electric motor helps move the existing steering linkage.

What does an electric power-steering torque sensor measure?

The sensor detects steering-shaft torque so the controller can choose assist.

Why is assist often stronger at parking speed?

Low-speed maneuvering creates greater steering torque demand.

What is a key difference between hydraulic and electric assist?

The assistance source differs, while both help the mechanical steering system.

What should a driver do if power assistance suddenly disappears?

Mechanical steering may remain, but much higher effort and an underlying fault require attention.
