Level 0 to 9. It determines the scaling factor between the speed of the steering
wheel and the speed of the steering motor but only when the steering wheel is fast
turning. By increasing the SPEED LIMIT value, the steering motor speed increases
too. In practice, it sets the maximum motor speed when the steering wheel is fast
turning.
Level 0 to 9. This setting performs the dynamic numbness compensation : it consists
of a reduction in the steer sensitivity when the truck is driving at high speed.
To get this goal, it is necessary to attenuate the scaling factor between the speed of
the steering wheel and the speed of the steering motor. AUX FUNCTI ON #3 does
that but only when the steering wheel is fast turning. This attenuation must be
proportional to the drive speed. At full drive speed the attenuation of the scaling
factor is maximum.
AUX FUNCTION #3 to Level 0 means no attenuation of the scaling factor with the
truck speed. AUX FUNCTION #3 to Level 9 means maximum attenuation of the
scaling factor with the truck speed.
Obviously, to perform the dynamic numbness compensation, it is necessary to know
the drive speed and so the eps-ac0 must be CAN Bus connected"
Level 0 to 9. It determines the scaling factor between the speed of the steering
wheel and the speed of the steering motor but only when the steering wheel is slow
turning. By increasing the SENSITIVITY value, the steering motor speed increases
too. In practice, it changes the sensitivity of the steering wheel when it is slow
turning.
Level 0 to 9. This setting performs the dynamic numbness compensation: it consists
of a reduction in the steer sensitivity when the truck is driving at high speed. To get
this goal, it is necessary to attenuate the scaling factor between the speed of the
steering wheel and the speed of the steering motor. AUX FUNCTI ON #2 does that
but only when the steering wheel is slow turning. This attenuation must be
proportional to the drive speed. At full drive speed the attenuation of the scaling
factor is maximum. AUX FUNCTION #2 to Level 0 means no attenuation of the
scaling factor with the truck speed. AUX FUNCTION #2 to Level 9 means maximum
attenuation of the scaling factor with the truck speed.
Obviously, to perform the dynamic numbness compensation, it is necessary to know
the drive speed and so the eps-ac0 must be CAN Bus connected.
Level 0 to 9. It sets a minimum amount of motor torque when the steering motor is
slow turning. It is useful (together with the ANTIROLLBACK parameter) to neutralize
the recall torque generated by the elastic tyre on the steered wheel.
Level 0 to 9. It is used to set the proportional contribution to a PID algorithm for
AUTC functions.
The proportional contribution is applied to the difference between the commanded
position and the real position (steered wheel angle). The accuracy of the pursuing
between commanded and real position increases if KP increases. It is used in
closed loop applications.
