FEV Smart Vehicle Development

360° Vehicle Development - Assisted, Connected, Electric
FEV SmartDrive Vehicle

Connected and Automated

Fully-connected vehicles and driver assistance systems (ADAS) – going as far as automated driving – as well as alternative solutions for propulsion and mobility: FEV works with these aspects of the intelligent vehicles and powertrains under the umbrella of "FEV Smart Vehicle Development" – and has been doing so for years. In addition, FEV offers tailored vehicle development services and solutions for lightweight construction that take account of the influences of these new mobility concepts on design and vehicle architecture.

Take a look at our Smart Vehicle Demonstrator Fleet.

A Solution for every Challenge

Our services are aiming at our classic customer base, such as automotive OEM and suppliers. However, the increased need of automotive development for new business models also puts new groups of customers on the schedule: for example, more and more technology firms, startups and insurers are using our services, profiting from FEV's in-depth expertise in industry and technology.

From the Idea to Concept to Series Production – and beyond

Even before development, we support market and technology studies, set up classical and digital business models and create concepts that we put on the street and test as demonstrator vehicles. When clients hire us to do so, we develop hardware components and control software and perform extensive and standardized testing and validation tasks. In doing this, our engineers and advisors have a view of the entire eco system, consisting of the vehicle, the propulsion system and the environment, and are in a position to implement the development process from idea to concept, all the way to production-readiness.

Standardized Methods and Tools

Standardized methods and tools are important elements for ensuring rapid development results and a large degree of validation. Even in verifying and validating driver assistance and telematics systems, we use methods that are most common, for example in powertrain and vehicle development. Modern simulation and modeling tools, including Model in the Loop (MiL), Software in the Loop (SiL) or Hardware in the Loop (HiL) solutions, make it possible to conduct automated tests during an early stage of development. In addition, we develop customized test systems for our clients. These include, for example, HMI, telematics and cyber security test benches that can be used for automated validation of the human-machine interface or data exchange between the vehicle and its environment (such as cellular communications or GPS). Modular, real-time simulation models for vehicles, drivers, connectivity and environment are used for this purpose and can be quickly tailored to the project application in question. In addition to the testing systems, the FEV Embedded Systems Test Center develops test strategies and methods to adjust testing efforts to quality goals and to optimize them. To do that, our test managers oversee not only compliance with the testing strategy, but also follow up on quality defects and evaluate current software quality using selected key performance indicators.


The experienced team at FEV Consulting is a source of new and fresh ways of thinking. The consultants can assist with creating new ideas and devising new business models. They prepare market and technology studies, potential analyses, technology and product strategies, and detailed concepts.

  • What does the future look like for digital idea creation processes and new business area developments?

Future Vehicle Concepts

Vehicle Development from Concept to SOP

Automated driving, connectivity and innovative, needs-based electrification lead to new mobility concepts and will deeply affect future vehicle concepts: As the former vehicle driver becomes less involved in the driving process, he will be able to redesign his journey time. Thus, especially the comfort needs, including infotainment, thermal comfort, NVH, but also design of vehicle space as well as ergonomics, gain more importance. Also the powertrain can make an important contribution to that by enabling smooth acceleration and gear changes. These altered requirements must be considered early in a 360° vehicle development process and integrated into a holistic vehicle concept.

Interior Design

The vehicle interior changes within the scope of automation and connectivity from the classic passenger cabin to the full-fledged lounge that enables working, teleconferences or leisure activities. Our design teams know the resulting design specifications and realize them esthetically and functionally. In addition, the Human Machine Interface (HMI) offers new possibilities with regards to design and usability while demanding for an intuitive operating concept.

Vehicle Architecture

The electrification of the powertrain also impacts the vehicle architecture as these powertrains, especially with large battery solutions, are becoming an integral part of the body in white. In addition, it is important to compensate the weight of the additional components without affecting NVH, safety or the spacing: Efficient lightweight structures for large and small scale production series, an innovative material mix as well as sophisticated packaging are necessary to meet these requirements. The Imperia FlexBody® toolbox system combines profiles and node structures from different materials into a global bodywork concept, thus enabling new possibilities for an individual high performance body structure.

Veränderung der Fahrzeugarchitektur

Electric Vehicle Concept: Imperia UrbE®

The Imperia UrbE® electric vehicle concept is inspired by the unique design characteristics of a golf cart. It was designed for use especially in suburban and inner-city conditions. The body structure of the 2.7 meters long vehicle is based on the Imperia Flexbody® technology that offers safety at the level of large-scale production vehicles and a very low weight. Instead of a conventional trunk lid, an innovative drawer design was chosen which not only makes the loading easier, but can also be used as bike rack.
The vehicle’s interior scores with a lot of space and the easy operability. The free-floating dashboard and the driver module, named “HIILO”, manage to combine these two features. Only 8 buttons are needed to operate all main functions. During the ride, the driver barely has to take his eyes off the road as he is supplied with all relevant driving information via the front screen which is similar to a head-up display. Card data or infotainment is assumed by a centrally arranged touch display.

Automated Cyber Security Testing
FEV was responsible to use its test automation platform to create an automated cyber security test system. This system allows the customer to create a variety of specific cyber security use & test cases that can then be tested on an automated basis instead of manually. The test system created, simulates numerous signals (wired and wireless) that the device under test is normally receiving in a vehicle in order to be able to create various scenarios that the test system is then able to automatically execute. The test system is a very powerful and flexible platform to create and execute tests that stress the device under test but also assure that tests can be consistently repeated numerous times using the exact same conditions. Testing of new cyber security solutions as well as extensive regression testing is now possible for the customer to be executed in a very short period of time.

FEV was responsible for:

  • Complete design, development and integration
  • Management of vendor integration of custom security testing tools
  • Test case development of threat actors from remote attack surface
  • Execution, verification and validation of manual test cases for automated system

Focus on System Thinking Instead of Components

From the development point of view, the increasing connectivity of vehicles means that countless new functions, suppliers and development tasks rise up. Besides the interaction of the many new elements, a significant challenge is that authentic, vehicle-specific functions are no longer being implemented and that their sphere of influence is no longer limited to only the vehicles. Instead, external features and functions also affect the highly-sensitive areas of safety, security, and reliability.

To master the numerous resulting interactions within and outside the vehicle, it is essential to consider the entire ecosystem in every step of development. Thanks to our extensive specialized knowledge in all involved automotive and the non-automotive areas, FEV as a development service provider combines these aspects and thus makes development run seamlessly – from planning to realization and validation of the processes all the way to implementation and validation of the solutions. Proven tools and methods are used for all of the above.

Cyber Security (Automotive) - Big Data and Cloud Services

Cloud Services

As part of various research and development projects, FEV makes use of the advantages of cloud services – such as for range computations for electric vehicles: real-time data on the vehicle, battery status and driver behavior as well as information about the traffic situation, local topography and ambient temperature can be combined with stored driving profiles and data to come up with a range estimate. This yields a reliable prediction of the expected battery range.

Project OSCAR

FEV Project OSCAR - Open Service Cloud for the Smart Car

Additional functions through apps, optimized dealership services and range predictions for electric vehicles: FEV and leading research and development partners have pursued these and other goals within the OSCAR (Open Service Cloud for the Smart Car) joint project. Using vehicles provided by FEV and StreetScooter as a basis, modular structures for information and communications technology were developed to integrate the vehicle into a cloud service. Drivers and fleet operators thus have access to important planning data and additional functions.

Automated Driving

Automated Driving - Streets Automated Driving - broken car Automated Driving - sensors Automated Driving - car Automated Driving - warning sign

On the Way to SAE Level 5

Already today, a number of driver assistance systems, including the lane-keeping assistant, distance warning and emergency braking assistance, are available as mass-produced products for driver support. In the future, the degree of automation in vehicles will increase even more, eventually allowing highly or fully-automated driving. To do that, it is not only necessary to integrate various sensors and to process lots of gigabytes of data per second; a corresponding legal framework must be achieved as well – both in this country and internationally.

In practice, we already have a Smart Vehicle Demonstrator Fleet in operation.

Automated Driving - ADAS (advanced driver assistance systems

Advanced Driver Assistance Systems (ADAS)

With the increasing capabilities of advanced driver assistance systems (ADAS), various types of environmental sensors are making their way into vehicles. In addition to ultrasound and radar, lidar and camera systems must be integrated and thus require additional expertise in integration, controls and validation.

These projects include:
  • Adaptive Cruise Control Benchmarking
  • Integration of powertrain and ADAS/AD components for series development
  • Multi-purpose camera validation including test planning, data analysis and event finding

Predictive Operation Strategies

Automated Driving - Predictive Operation Strategies

The predictive hybrid operational strategy and predictive HVAC not only decrease fuel consumption and CO2 emission, but also improve drivability of the vehicle. This is an important step towards autonomous driving which offers instant customer benefits which make a broad acceptance of the concept probable.

These strategies consider locally available parameters such as current driver’s request, vehicle velocity, battery state of charge, etc. and combine them with information about future road profile, traffic and infrastructure as well as future driver’s request to optimally control vehicle operations.

DENSO and FEV are currently developing a predictive operating strategy including an electronic horizon that not only achieves additional fuel consumption savings in the real driving scenarios, but also increases the drivability of the vehicle. The strategy is based on using a-priori knowledge of the road ahead from the vehicle’s navigation system in combination with data about provided street topography and traffic information, speed limits and traffic lights status through car-2-x technology. Utilizing this data, an optimized operating strategy for the powertrain as well as for the HVAC system is determined for a specific period of time.
