New GM digital vehicle platform to enable future technologies
The new electronic platform, says the company, is necessary for its next-generation of vehicles, EVs, active safety, infotainment, and connectivity features, as well as the evolution of its Super Cruise driver assistance feature. The platform is installed on the company’s newly-unveiled Cadillac CT5, and is expected to roll out to most GM vehicles globally by 2023.
Over the next five to 10 years, says the company, more electrical bandwidth and connectivity will be needed in vehicles to ensure that features like electric propulsion systems, the Super Cruise driver assistance feature, and advanced active safety systems can all run in conjunction with each other. The new platform powers an electronic system capable of managing up to 4.5 terabytes of data processing power per hour – a fivefold increase in capability over the company’s current electrical architecture.
In addition, an expanded capacity for smartphone-like over-the-air (OTA) software updates enables the adoption of functionality upgrades throughout the lifespan of the vehicle. The new architecture also provides more rapid communications within the vehicle itself and to outside sources with Ethernet connections of 100 Mbps, 1 Gbps, and 10 Gbps.
“The critical role of software and its importance to our vehicles, both now and for years to come, cannot be overstated,” says GM President Mark Reuss. “Our new digital vehicle platform and its eventual successors will underpin all our future innovations across a wide range of technological advancements, including EVs and expanded automated driving.”
Additional protective features at the hardware and software levels offer cybersecurity features focused on protecting against the potential risk of unauthorized access to vehicles and customer data.
The electronic platform was developed at GM facilities across the globe by a team of electrical, hardware and software engineers.
