Hydraulic power steering Electric power steering
1. OVERVIEW
The electric power steering, EPS, does not have any belt-driven steering pump constantly running, so it
is lightweight and the motor consumes energy only when the steering wheel is turned by the driver, and
this leads to improvement in fuel efficiency. Also, the elimination of a belt-driven pump and its
accessories greatly simplifies manufacturing and maintenance. While offering these benefits, as it does
not contain any steering oil, the environment is not polluted both when the steering system is produced
and discarded.
In other words, the electric power steering (EPS) system uses the electric motor to assist the steering
force. It functions independently regardless of whether the engine is running or not, unlike the existing
hydraulic power steering.
The EPS system generates an assist steering force variably depending on the driving conditions by
controlling the motor's operation, based on the input signals from the sensors such as torque sensor and
angle sensor. In turn, the EPS receives the torque signal by the driver's movements of the steering
wheel, as well as the vehicle speed, and uses the motor to determine the assist torque. The EPS
controls the motor for this. Another features of EPS are fail-safe function, diagnosis function,
communication function between units and interface function for external diagnostic device.
The EPS system components such as the torque sensor, steering angle sensor, fail-safe relay, etc. are
located in the steering column and EPS unit assembly.
Advantages: ▶
Assurance of improved steering
Provides optimal steering force according to the
vehicle speed
Enhanced steering stability while driving at high
speed (1)
-
-Reduced fuel consumption
Consumes energy only when steering wheel
is turned (improved by 3 to 5%)
Energy saving (reduced by 85% compared
with hydraulic power steering)
Reduced number of parts: Elimination of
steering pump, hydraulic hose, pump pulley,
oil reservoir, belt, bracket, etc. (2)

2. OPERATION
When the driver turns the steering wheel, a torque is generated and the torque sensor and the steering
angle sensor in the EPS system detect the rotation of the steering column to run the electric motor. At
this time, the worm gear connected to the motor drives the helical gear mounted to the steering column
to generate the assist torque for the steering column. This allows the driver to operate the steering wheel
easier.Output torque = 1) Steering force (manual torque) + 2) Assist torque

3. OPERATING CONDITIONS
A. Front Air Bag System
The air bag does not deploy when: ▶The air bag deploys when: ▶
The air bag can deploy when: ▶A front collision occurs, which occupants cannot be protected by seat belt. -
The vehicle rolls over or tips over sideward, or a side/rear collision occurs.
the impact of the collision is low enough for the seat belt to protect the occupant properly. -
-Underbody impact from the road surface, impact against the curb at a very high speed, or
dropping impact onto the road surface with a large angle occurs. -
Seldom oeprate ▶
A collision to diagonal direction (not a front collision) occurs or the vehicle tips over.
A weak collision, which the sensor cannot detect, occurs (under the activation requirements).
A collision against narrow objects such as a telegraph pole or a tree occurs.
The vehicle falls into a drainage or a puddle.
The front of the vehicle crashes into high impact point vehicle such as a truck.
The hood is hit by falling stones.
The air bag warning lamp is on. -
