3) Basic ABS Control
▶ Operation of ABS control unit
Reference speed
▶
The reference speed is the mean, I.e. average speed of all wheel speeds determined by simple
approximation.
Simplified ABS control
▶
If, during braking, one wheel speed deviates from the reference speed, the ABS control unit
attempts to correct that wheel speed by modulating the brake pressure until it again matches the
reference speed. When all four wheels tend to lock, all four wheels speeds suddenly deviate from
the previously determined reference speed. In that case, the control cycle is initiated again in
order to again correct the wheel speed by modulating the brake pressure.
Applications of the ABS control unit The
signals produced by the wheel sensors are
evaluated in the electronic control unit. From
the information received, the control unit must
first compute the following variables:
- Wheel speed
- Reference speed
-
Deceleration
- Slip
