Gyro (Angular Speed Sensor)NBEL0228S0204IThe oscillator gyro sensor is used to detect changes in vehicle
steering angle.
IThe oscillator gyro periodically senses oscillatory variation at
the oscillation terminals. This variation is caused by changes
in the vehicle angular velocity. Voltage variations are sensed
by ceramic voltage sensors at the left and right sides of the
terminals. Vehicle angular velocity corresponds directly with
these changes in voltage.
IThe gyro is built into the display & navigation (NAVI) control
unit.

DescriptionNBEL0228S0206IDisplay area: Trapezoidal representation showing approximate
distances (Wn, D, and Wd).
ITen horizontal grid lines indicate display width while six verti-
cal grid lines indicate display depth and direction.
IDrawing line area shows open space, depth, and immediate
front area. Each area is to a scale of approximately 5:6:25.
IWhen the ªZMþº button is pushed, the view point height is
increased. Pushing the ªZM+º button decreases the height.
Pushing the ªZMþº button or the ªZM+º button during operation
indicates the scale change and the view point height at the
left-hand side of the screen.

for minute decreases in wheel and tire diameter caused
by tire wear or low pressure. Speed calibration immedi-
ately restores system accuracy in cases such as when
distance calibration is needed because of the use of tire
chains in inclement weather.EL-409
