IN THE DRIVER’S SEAT Supporting automotive OEMs and suppliers


With the sustained growth of the automotive sector, time-to- market is tightening, as are the technological demands. Stefan Marxreiter, chief operating officer at Mobica, discusses how the company can assist in the development of a project


Christian Lynn: Mobica works with many companies to develop their automotive solutions – how do these relationships operate and what role does Mobica take?


Stefan Marxreiter: Mobica takes various approaches to the collaborative relationship with clientele. The dominant business model is that of contracts – Mobica holds direct contracts with many car OEMs and their suppliers. Typically, these operate under a fixed price, with the client providing Mobica with the specifications of their project. Other business models go from team extensions under time and material to a fixed level of effort engagements and an agile fixed price.


Away from a contractual


enterprise, there are more intimate partnerships, whereby Mobica and a relevant body work towards a common goal, even developing conjoint IP together, or the IP stays completely with the customer. Integration is the standard method of collaboration – bringing in members of Mobica’s team, so that the cooperation is direct and effective. This can be done in on-site engagements, as well as in off-site projects with very close communication. Both options deliver the necessary impact, resulting in a clear, concise solution to an automotive challenge. But to summarise Mobica’s exact role, from time and material to

agile fixed price, the company takes on a strong role to assist clients in their automotive ambitions.


CL: Looking at a specific collaborative effort, Mobica and Silicon vendors are working together on the digital cockpit – could you explain how these digital displays function?


Stefan Marxreiter, chief operating officer, Mobica


SM: The basis of the application is a complete change from the analogue display that currently stands. It operates with several microcontrollers, one of which is a system-on-chip that’s responsible for drawing everything in on the display, a display that is tasked with delivering a high frame rate (>60FPS, to avoid any unwanted flickering). The key to its success is the combination of high ASIL level components with complex software that meets lower ASIL certification levels. Fastbooting and managing the procurement of and the display of information from other devices in the car (e.g. the navigation system) is key to its success. Considering the convolution of requirements for autonomous driving, the digital cluster is tasked with quite a lot of functions. The user wants an operable, understandable and configurable cluster in the car. In the background, you must decide what details to show in specific situations to


the driver without distracting him too much. Additional features, like driver monitoring and health data collection, will be committed to the digital cluster.


CL: For such a digital cockpit, which


delivers such a simultaneous stream of information, cars will require an ecosystem of sensors, taking in this information at a constant rate. How does Mobica foresee this transformation? Is there a concern of excess – balancing technological assists and human agency?


SM: Continuing from where we left off with the last question, while the analogue domain is still alive and present, the digital world is taking off and exhibiting all of the signs of continual growth – lower cost, time savings, etc. Sensors are an essential part of translating the digital into our analogue world, particularly in the sector we are discussing: autonomous driving and ADAS, driver monitoring systems, these require the continual transmission of information from sensors wired into the car, active at all times, to ensure optimal functionality. These, in turn, guarantee the functionality of the driver – keeping track of health defects, ensuring the attention of the driver, making the user aware of personal hazards such as fatigue and overheating: all of these are relevant concerns that not only inform the need to implement a big number of sensors within a single motor vehicle at any one time, but also demonstrate the importance of human agency, with the aim of restoring thorough concentration from the driver.
