UniTrain Course – CAN bus in commercial vehicles

ABOUT THIS PRODUCT:

In commercial vehicles, communication between the various control units as well as sensors and actuators play a decisive role. With more extensive automotive electronification this requirement will grow, and new fields of application will open. In this context, the safety-relevant and multimedia sectors deserve special mention.

To meet the requirement, many different bus systems have been developed. Over time, however, one bus system has made a special name for itself – the Controller Area Network – Bus, or CAN-Bus for short. Exactly this bus system is the content of this course. On the following pages you will get a detailed and comprehensive insight into the theory and practice of this bus.

Includes:

• 2 Experiment cards (front and rear of truck) with emulation of a complete CAN bus system for utility vehicles including actuators, sensors, and dashboard
• Two microcontroller systems with communication via the CAN bus
• Cascading via CAN-IN and CAN-OUT on Sub-D9 connectors
• CAN node I with indicators, lights, simulated key, fuel tank indicator, temperature sensors, and more
• CAN node II with rear light, fuel tank simulation, electric window, central locking functions, and more
• Labsoft browser and course software

 Course contents:
