4.8.6 Driving
Introduction
To be able to drive the truck, the operator seat must be loaded, the
safety pedal depressed, a direction of travel selected, and the acceler
-
ator depressed.
If the operator seat is not loaded and the safety pedal is depressed, a
disable indication will be displayed in the CID.
If no direction has been selected, the two green arrows that indicate
direction alternate.
If the accelerator is depressed before the safety pedal or the seat is
depressed, the accelerator must be released before then being
depressed again.
Acceleration and speed reduction
When the accelerator is depressed, the MCU will determine the highest
applicable speed and increase the speed by using the ACT to regulate
the frequency of the drive motor three-phase voltage.
The maximum speed is parameter-based.
Pressing hard on the accelerator results in sudden acceleration, and
pressing lightly results in more restrained acceleration.
The acceleration is parameter-based.
Once the accelerator is released the motor brake will be activated and
the speed will be reduced. The more the pedal is released, the greater
the retardation.
The retardation is parameter-based.
Monitoring
Acceleration is reduced when battery voltage is low, as well as in emer-
gency driving mode.
Retardation is reduced in emergency driving mode.
Speed is monitored so that actual speed is reduced when retardation is
requested.
