Vehicle Data Management

Smart Solution for Vehicle Data Management

A joint solution from Bertrandt and b-plus for the entire value chain of ADAS/AD data acquisition.

The reliable validation of ADAS/AD functions requires that all data are made visible. In addition to an optimum, requirement-specific, and technical vehicle integration solution for measuring equipment, Bertrandt also provides you with all the necessary sensors, and ensures the associated system networking and connectivity. At the same time, you can use our solutions to further process the measured data you have collected, as well as analyzing them with the aid of AI, and evaluating them in accordance with your requirements.       

Our focus is on you as our customer and your entire value chain. We provide you with all services from a single source: from development and the construction of a test vehicle, to worldwide testing and the AI-driven evaluation of your data, regardless of whether this takes place in-vehicle or off-vehicle. It goes without saying that we also support you by assuming responsibility for data and vehicle logistics as well as test planning and coordination of your vehicle fleet.

In order to guarantee that your measuring tasks are performed with a high quality and without failures or loss of data, it is necessary to merge together the hardware and software of the measuring equipment, the vehicle functions, and the peripheral systems, such as the cooling system. Only with the aid of powerful and reliable measuring equipment is it possible to develop and validate viable systems. The key factor is how well this measuring equipment works within the complete vehicle system. This requires a strong energy supply, a reliable and user-friendly operating concept (HMI), and sufficient cooling for the measuring equipment itself.

Increasingly complex measuring technology is resulting in an increase in the requirements for integrating the measuring equipment into the vehicle. This is particularly relevant for the electric power supply, thermal loads (cooling), and the human-machine interfaces of the measuring systems. Only with highly developed integration of measuring equipment into the vehicle and the merging of the different measuring systems through intelligent peripherals is it ultimately possible to keep vehicle downtimes as short as possible and to ensure a highly cost-effective use of the test vehicle.

Even in large vehicles, space requirements have become a real challenge in the meantime. Without a targeted installation space analysis, it is no longer possible to integrate extensive measuring equipment and sensor set-ups in particular into the vehicle. Typically, this is evaluated and optimized in advance in a CAD-based installation space analysis. Aspects such as air guidance, accessibility, modularity, exchangeability, and cable routing need to be taken into account.

Many test drives end without results, for example because the measuring equipment did not work properly or because a technical defect occurred. Often, this only becomes apparent after weeks of time-consuming and costly testing. These problems can be significantly reduced by secure and above all “supported” operation of the measuring systems. Smart software solutions, such as checklist-based start-up and shutdown procedures similar to those applied in aviation and using a tablet computer, are now essential. Intelligent, software-supported operating strategies that are adapted to your use case can help to avoid errors. These strategies can recognize early on when hard disks are getting too full, can forecast how much battery life remains, or can even protect the measuring systems and the data by initiating a proactive shutdown, for example in the case of overheating or a short circuit. Finally, live in-car analytics can detect dirty or disconnected sensors and provide the necessary feedback to the driver.

As computing power increases, the amount of waste heat and the electric power requirements of the computer systems in the vehicle also increase proportionally. Without active controlled cooling (air or water cooling) and a power management system that is designed for the amount of power required, safe and stable operation of the measuring equipment is not possible. In the meantime, electric power consumptions of more than 3000W or waste heat quantities of more than 300W are not uncommon. Especially the poor heat transfer coefficients of cooling by air convection leave no other choice than water cooling. A stable energy supply requires a power management architecture which, in addition to using the vehicle’s on-board power system (generator) through a DC/DC booster, also contains additional batteries for the measuring equipment and an on-board charger to operate the vehicle in the workshop, as well as resettable fuses in many cases.
