Data loggers play a vital role in modern vehicle development. They record and analyze vehicle data, especially during the testing of new vehicle models. With their help, control unit as well as bus communication within the vehicle can be monitored and all available analog as well as digital signals can be recorded in order to identify errors and evaluate road performance under real-life conditions.
Data loggers are electronic measurement devices that acquire and store data from various sources. In the automotive area, they record the data traffic (signal- or trace-based) of the vehicle bus systems, such as ETH, CAN FD or LIN, as well as analog data. These data can then be used for evaluation, optimization, and diagnostics.
A typical automotive data logger includes several components:
During measurement, the logger records the communication between the control units. Messages can be filtered and stored in different formats. Modern devices can also analyze the data in real time and transfer them, if necessary, via modem or WiFi to a company server or the desk of an employee.
Data loggers are used in various areas of the automotive industry:
When developing new vehicles, it is essential to analyze the interaction of all electronic components. Data loggers can record sensor and control unit data, evaluate them, and provide an error analysis, if needed. Detailed data acquisition at an early stage is especially important for the introduction of new drive technologies, such as electric or hybrid drives.
Data loggers are used to analyze the reliability and lifetime of components in durability tests. These tests help identify potential weaknesses early on. By recording vibration and oscillation patterns, developers can gain insight into material fatigue and wear.
For sporadic errors, a continuous data acquisition is essential. Data loggers can trigger critical events, record configured measurement data, and aid with error analysis. This helps workshops and developers locate and fix problems and sporadic malfunctions efficiently, saving time and money.
Modern fleet management systems use data loggers to monitor fuel consumption, road performance, and vehicle condition, thereby increasing efficiency and reducing costs as well as facilitating the planning of maintenance intervals and minimizing unexpected downtimes.
The ever-growing automation of driving changes and increases the requirements regarding data acquisition and storage. In addition to the usual automotive networks, such as CAN, LIN, or FlexRay, high speed data from cameras, radar systems, and LIDAR have to be recorded as well, e.g. in order to precisely analyze the vehicle environment. This helps developers optimize algorithms for autonomous driving.
