Power Steering System

When the driver is not exerting force such as when driving in a straight line the system shouldn t provide any assist.

Power steering system.

Power assisted steering overcomes the problem. These modules share information for vehicle speed steering angle and engine operation. A power steering system should assist the driver only when he is exerting force on the steering wheel such as when starting a turn. On this network is the ecm for the engine and abs stability control system.

The electric power steering system is typically part of the hi speed can bus on the vehicle. In motor vehicles a power steering system helps drivers steer the vehicle by augmenting steering effort needed to turn the steering wheel making it easier for the vehicle to turn or maneuver. Valves in the steering rack or box open whenever the driver turns the wheel allowing oil into the cylinder. Hydraulic or electric actuators add controlled energy to the steering mechanism so the driver can provide less effort to turn the steered wheels when driving at typical speeds and reduce considerably the physical effort necessary to turn the wheels when a vehicle is stopped or moving slowly.

The oil works a piston that helps to push the steering in the appropriate direction.
