Section 07 CHASSIS
Subsection 03 (DYNAMIC POWER STEERING (DPS))
Steering Torque Sensor
rmr2008-019-017
The steering column is connected to the shaft on
the DPS unit. A small area of the DPS shaft is
magnetized. Inside the DPS unit, a torque sensor
surrounds the magnetized area of the DPS shaft.
When the handlebar is turned, torque is applied to
the shaft which tends to twist the shaft slightly,
deforming the magnetic field in the shaft. The
sensor detects the torque by measuring the devi-
ation of the magnetic field.
The torque sensor is very sensitive and can de-
tect very small changes in the magnetic field.
The harder the handlebar is turned, the greater
the magnetic deviation, the greater the power
steering assist.
