Smart Logger

High Performance Data Logging

In‑vehicle data acquisition combines large data volumes from sensors, cameras, ECUs and networks.
Smart Loggers provide a robust, temperature‑proven logging solution combined with matching software for data acquisition and evaluation.

Highlights

Direct project usage: Use your existing CANape or vMeasure project directly on the Smart Logger to save time and ensure process reliability
Real‑time evaluation during measurement: Perform live evaluations, real‑time statistical analyses and virtual signal calculations during runtime – including external algorithms
Time‑synchronous data acquisition: Synchronize measurement data from sensors, ECUs, cameras and networks with high precision via IEEE 1588 PTP or software‑based synchronization

Central logger and fleet management: Centrally manage and monitor Smart Loggers via Mobile UI, vLoggerControlRoom and cloud services, including status and location information
Scalable performance platform: Use optimally matched hardware and software platforms from VP6400 to VP7500, expandable with logging extensions for increasing data rates

Mode Variants

The Smart Logger combines a vehicle-compatible computer from the VP family with CANape log or vMeasure log. Your existing CANape and vMeasure projects run on the Smart Logger. They operate in two modes.

Interactive mode

You connect the computer running CANape or vMeasure to the Smart Logger via Ethernet. All ECUs, buses, and sensors are connected to the logger. You use CANape/vMeasure as usual on your computer and work on your project. If you want to switch to stand-alone mode, disconnect the computer from the Smart Logger.

Standalone mode

The Smart Logger performs the logging task for your project independently. A test driver accesses the Smart Logger via a browser, triggers actions, and receives information about the logging status.

Software Options

Depending on your application, two software options are available: vMeasure log and CANape log.

When to use vMeasure log?

vMeasure log is suitable for the time-synchronous acquisition of many signals from different sources. Sampling rates in the megahertz range per signal and a powerful analysis library allow for the precise calculation of electrical performance data such as active power and inverter efficiency already during the measurement. Protocols, hardware interfaces, and reference cameras are supported.

When to use CANape log?

CANape log extends vMeasure log to include ADAS/AD sensors. It logs data from cameras, radar, LIDAR, and other high-bandwidth sources such as Automotive Ethernet. Connect a laptop to the Smart Logger via Ethernet using CANape and gain full access to the ECUs for calibration or flashing.

Hardware Variants

The VP6400 and VP7500 hardware platforms are available for Smart Loggers. The VPs are designed for in-vehicle use, record large amounts of data, and process it in real time during recording thanks to powerful processors. The platforms offer integrated ports for CAN, CAN FD, LIN, and FlexRay, as well as numerous Ethernet interfaces. You can flexibly adjust the number of ports using additional VN network interfaces. If data rate or CPU performance is not sufficient, add logging extensions: a single extension increases the write rate by up to 6 GByte/s.
