The Visteon- and Cisco-developed OASIS (Optimized, Adaptable, Secure, Intelligent, Seamless) concept makes secure car-to-cloud communications the prerequisite for unlocking vehicle network connectivity-associated benefits.
Adding data buses allows new electronic features, but increases costs from wiring and modules. SAE Congress speakers suggest taking advantage of opportunities to transfer functions and merge modules; and they propose algorithms to give engineers greater choice in circuit routing through harnesses, to replace trial-and-error techniques.
The system uses specific Sport Mode algorithms with modules from the high-speed CAN data bus, including those for adaptive cruise control, forward facing camera, all-wheel drive, shift-by-wire, electric power steering, transmission, and powertrain.
Dangers from malware, including ransom demands, must be pro-actively avoided as industry and owners enter era of connected cars. For all their conveniences, telematics could pose ugly series of risks that will require new approaches to prevent, explains Cisco Systems scientist to SAE Congress attendees. Vulnerabilities are in many areas, including the OBD system.
