GM unveils digital vehicle platform; 4.5 TB/h; installed on new Cadillac CT5, rollout to most GM vehicles globally by 2023
21 May 2019
General Motors President Mark Reuss unveiled the company’s all-new electronic platform necessary for its next-generation of vehicles, EVs, active safety, infotainment and connectivity features, and the evolution of the Super Cruise driver assistance feature.
The technology powers an electronic system, capable of managing up to 4.5 terabytes (TB) of data processing power per hour, a fivefold increase in capability over GM’s current electrical architecture.
As the automotive industry and vehicles evolve in the next five to 10 years, more electrical bandwidth and connectivity will be needed to ensure that features such as electric propulsion systems, the Super Cruise driver assistance feature and advanced active safety systems can all run in conjunction with each other.
Debuting on the recently-unveiled 2020 Cadillac CT5 sedan, the electronic platform will go into production later this year and should be rolled out to most vehicles within GM’s global lineup by 2023.
With an expanded capacity for smartphone-like over-the-air software updates, the system 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. 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.—Mark Reuss
Cybersecurity is another key pillar of the new architecture. The system’s DNA includes additional protective features at the hardware and software levels that reflect the company’s foresight in this regard.
GM was among the first automakers to create an integrated and dedicated global Product Cybersecurity organization, a team of experts within the company focused on protecting against the potential risk of unauthorized access to vehicles and customer data.
GM implemented years ago a security vulnerability disclosure program to engage more closely with the research community. It has matured to become a formal “bug bounty” program that continues to further strengthen GM’s cybersecurity efforts.
GM also chairs the Auto-ISAC (Automotive Information Sharing & Analysis Center), a community of private and public-sector partners that shares and analyzes intelligence about emerging cybersecurity risks for the automotive industry.
The electronic platform was developed at GM facilities across the globe by a team of electrical, hardware and software engineers.
