Automotive networking standardisation efforts need to continue

23 February 2005 News

For years, in-vehicle communications networks have been comprised of dozens of incompatible and proprietary standards, even among vehicles from the same automaker. However, as more electronics enter the vehicle, network standardisation needs to become the rule.

One of the areas in dire need of new, higher-speed networks is the vehicle powertrain. According to findings from ABI Research, the most commonly found protocol for high speed automotive powertrain is currently CAN, however increasing demands from new powertrain management technologies such as displacement-on-demand, direct fuel injection, variable valve timing and shift-by-wire are pushing CAN to its limits.

"For advanced powertrain applications, automakers have been discussing time-triggered networking for years, with little to show for it," says Dan Benjamin, an automotive analyst for ABI Research. "We believe FlexRay will finally become an adopted time-triggered network protocol within three years, and the industry will finally stop dragging its collective feet."
