Test buses in Germany’s capital
Berlin has more than 1300 city buses that carry passengers daily from one point to another. It is no longer a secret that you can simply board the bus lines 100 or 200 to take a tour along the major sights for little money. It's no wonder then that city buses are quite popular with tourists and locals alike.
However, with such a high frequency of passengers, it is important that the vehicles are put through their paces and tested in real operating conditions. For the fleet to live up to a high standard, new vehicles must undergo extensive road testing – as with the new buses ordered by the BVG from the Dutch manufacturer VDL. When it comes to equipping their buses with test and measurement systems for road testing, VDL relies on imc.
Mobile data acquisition on the VDL city buses is performed using the imc BUSDAQ-2-ET as well as imc CANAS-INC and -SCI systems.

Mobile data acquisition
Who really cares for passengers will gladly perform a curtsy: this is what the VDL Citea LLE buses do. With a small hiss, the bus will lower down to meet its passengers. Instead of just tilting to the right, the entire bus will lower evenly for the entering and exiting guests. For elderly passengers, the boarding process is now a cinch. In addition, thanks to lighter floor and roof panels, the twelve meter long bus consumes significantly less fuel as before.
At the moment, two Citea LLE city buses, as well as a double-decker Citea DLF are now equipped with imc measurement devices and are tested during running operations. With the acquired measurement data, VDL can continuously optimize their vehicles. The compact and robust imc BUSDAQ-2-ET measurement devices capture data from the engine, transmission, air suspension system, brake system and dashboard – all via CAN bus.

The imc BUSDAQ series enables time-synchronous acquisition of measurement information from vehicle buses such as CAN or LIN. These compact systems are far more than a simple logger: they offer real-time calculation and trigger options. In addition, the imc BUSDAQ supports a variety of protocols, such as SAE J1939, which describes the CAN bus communication in commercial vehicles for transmission of diagnostic data (e.g., engine speed, temperature, error codes) and control information.
Due to its signal-controlled sleep mode, the imc BUSDAQ is particularly well-suited for fleet trials, especially with a start-up time of only 200 ms. imc BUSDAQ not only allows for the connection of vehicle buses, but also bus components such as sensors, measurement amplifier modules (e.g., imc CANSAS) or control devices.
Measurement data, status information, etc. can be read with the imc BUSDAQ. For road testing, having GPS capability and remote access to measurement data were an important feature.
Instrumented data logger: imc BUSDAQ
Just like all imc devices, the imc BUSDAQ is supported with the imc STUDIO software platform. This enables complete manual and automatic adjustment of the measurement parameters, real-time functions, triggers and storage modes. Curve window displays and documentation created in the Report Generator are an integral part of the software.
In addition, modules for capturing frequency, rotation, position and angle are in operation:
imc CANSAS-INC and -SCI modules for isolated recording of voltage, current and temperature.
They detect signals such as generator current and voltage, pulse width modulation, air compressor pressure and the status of the air conditioner.
