This functionality allows:
– high performance vehicle owners to measure wheel spin under acceleration and
wheel slip/lock under braking.
– calculating vehicle 'speed over ground'.
Vehicle speed calculation function
– Calculating vehicle speed of 2 wheel drive: (Wheel speeds of non-driven axle as input)
– Calculated speed is average of both speeds if speed difference between wheels <
limit.
– Calculated speed is maximum of both speeds if speed difference between wheels
> limit.
– Calculating vehicle speed of 4 wheel drive: (Wheel speeds of all wheels as input)
– Calculated speed is speed of 2nd fastest wheel.
