Background and assignment
• Earlier studies done by the Norwegian Public Roads Administration has shown positive effects of
ADAS, Advanced Driver Assistance Systems
• Possibility to retrofit cars with selected ADAS
• ISA
• Alco locks
• Speed limiters
• 9 selected car manufacturers
Swecos assignment (mid November 2013 – end January 2014)
• Identify technical challenges in retrofitting ADAS
• Electronics, battery capacity, other technical constraints
• Compatibility with selected car models
• Car manufacturers point of view
• How are the vehicles prepared?

• Speed locks
• Collecting information through:
• interviews with system and vehicle representatives via telephone and e-mail
• information from web-sites and other means
• Market scan
• What's available on the Scandinavian market?
• New technology
5
Selected systems
Systems selected by NPRA:
• Alco locks (CENELEC-certification)
• ISA (only informative available for the study)
• Speed lock (only one suggested for personal vehicles)
• Some systems not applicable for the study
• No technical demands
• Not available on the market
• Other reasons (such as certification, only for HGV etc.)

Questions to system suppliers
• System demands:
• Voltage: constant and ignition
• Current: stand by, heating and while driving
• Connection: ignition, pedal sensor and CanBus
• Car model compatibility:
• System compatibility with, for the study, selected vehicles
• General questions:
• How is your product installed in the vehicle, what needs to be done?
• Are there specific challenges when installing your product with certain types of vehicles/car
manufacturers?
• When connecting your device, what are the demands regarding interfaces? Analog or digital?

Analysis
• System supplier – high response rate
• Know their products and demands
• Familiar with selected vehicles
• Dependent on marketing
• Dependent on legislation
• Dependent on support from car manufacturer
• Technical development
• Car manufacturers – lower response rate
• General attitude is restrained
• Harder to respond to questions – needed more time
• Lower interest – answers depends on who’s answering
• Safety and warranty
• Corporate secrets
• Low knowledge, low or no experience with ADAS
• NPRA is an authority - cautious / careful with what they say
15
Analysis
Critical factors
• Access to ignition lock circuits and bus systems
• Intervention with safety-related systems that is not supported by the car manufacturer
• Installed systems that must be approved by the manufacturer and installation that must be
performed in a certified workshop
• More complexity in cars, new materials and technologies
• Battery capacity
• Technology development
• Time – everything needs to be thoroughly tested
16
Recommendations
• Dialogue
• Representatives from management and technical- and safety development sections
• Involve other car manufacturers
• Active ISA has higher demands on the vehicle
• Integrated ADAS – speed locks and ISA already in the vehicles
• Infotainment systems, Google and Apple
• Connected vehicles / cooperative systems
• Other platforms in the future?
• System suppliers more and more dependent on cooperation with car manufacturers in the future
