ABS/ESP control unit

ABS/ESP control unit. On the sensor side 4 rotational speed sensors (Hall or inductive) attached to the wheel, rotational and lateral acceleration sensors and a brake pedal can be connected. On the output side the actuator signals of the recirculation pump, of the 4 inlet and the 4 outlet valves and of the high pressure switch valves can be recorded. The steering angle is recorded via CAN bus from the steering column electronics 738111-02 and 739 654.

The experiment described below can be carried out:

• ABS
  Pressure change in the wheel brake cylinder (increase, hold, release)
  Full brake application on a non-slip road
  Full brake application on a slippery road
  
• ESP
  Driving manoeuvre: "rapid steering and correction“
  Driving manoeuvre: "track change with full brake application (Elk test)“
  Driving manoeuvre: "multiple steering and correction“
  Driving manoeuvre: "acceleration / braking in a tight curve“

For the recording of the measurement of the diagrams, the control unit is equipped with additional analogue outputs:

• Percentage of engine intervention
• Steering angle
• Sideslip angle
• Vehicle speed

For performing simulations driving situation, the control unit can be connected via USB to a PC. It is equipped with an fault memory and is self-diagnostic capable.
The conversion from km/h or mph for speed's display and Pa to psi for pressure's display is possible by coding.
