Cornering

When the vehicle is cornering, the upper sections

of the legs are bent by the Coriolis force for as

long as the vehicle takes to negotiate the corner.

A voltage is produced in the upper piezoele-

ments of the angle of turn sensor.

The level of this voltage is dependent on the

change in direction of travel.

When negotiating a corner from left to right, for

example, the sign before the voltage changes.

The angle of turn sensor only detects the angle of a single change of direction

The vehicle must be moving before a curve radius can be calculated.

Only then is the navigation control unit able to calculate the curve radius and

perform map matching using the data produced by the angle of turn sensor

and the ABS wheel speed sensor.

Straight-line travel

No Coriolis force occurs when the vehicle is dri-

ving in a straight line.

The upper parts of the legs are not bent and no

voltage is generated in the piezoelements.
