Digitalisierung: Vernetzte Kfz-Systeme LIN-Bus

The LIN bus training system - his master's voice! As "subbus" to the CAN data bus, the LIN bus is a single-wire bus that, upon request by the CAN bus master, supplies sensor data or activates actuator outputs. In automatic intermittent windshield wiper mode, the rain sensor recognizes the precipitation's intensity and sends this information via LIN bus to the electrical system control unit. This activates the wiper's motor - likewise via LIN bus - at an interval corresponding to the amount of precipitation: little rain = rare repetitions, a lot of rain = frequent repetitions of the wiper's movement. Spraying from an aerosol can activate the rain sensor.

The training system includes:

• CAN-bus-capable steering column electronics with wiper lever
• a CAN and LIN-bus-capable electrical system control unit
• a LIN-bus-capable wiper motor
• a LIN-bus-capable rain sensor
• a fault switching box (CAN and LIN faults).
