Mode 3: Automatic four-wheel drive detection
In this mode the starting resistance of the vehicle axle is monitored and evaluated. This
detects a vehicle axle that is not freewheeling, and an automatic switchover to reverse
operation takes place.
During the braking efficiency test, two measuring processes take place, between which
the direction of rotation is automatically reversed. The braking force of the respective
wheel turning forwards is measured.
After completion of the two measurements, the test bench rollers remain stationary
until the vehicle has exited the test bench.
NOTICE
•
In the case of automatic four-wheel drive detection, the vehicle engine must NOT
be switched off after driving on the test bench, otherwise correct four-wheel drive
detection is not possible.
•
In the case of counter-rotation operation, it is recommended to use a pedal force
meter as a measurement reference to determine the actual brake force differ-
ence.
