7-2. ELECTRIC POWER STEERING
7-2-5
SYSTEM DESCRIPTION (COMPONENTS)
EPS Unit
▪
The EPS unit is a self-contained unit that
includes the steering gear, the EPS module,
the EPS motor and the torque sensor.
▪
The EPS module provides DC power to the
motor. The amount and duration of that DC
power is determined by the inputs to the EPS
module. Reversing the polarity of the circuit
current changes the direction in which the
motor turns.
▪
The EPS motor does not
“
spin
”
, but rather
turns in very small increments based on the
amount, duration and direction of DC power
delivered by the EPS module.
