General Motors  A common criticism of the increasingly digital nature of new cars and trucks is that all these new features become shoe-horned in systems that are not designed with features such as connecting in mind. The ubiquitous Controller Area Network bus (CANbus) first appeared in a new vehicle in 1
991, long before anyone thought it was a good idea to connect each new car to the Internet. To that end, General Motors on Monday revealed a brand new platform architecture, designed with the needs of future-proof, connected autonomous electric cars in mind. "It's the vehicle's brain and nervous system, and it's five times better than what fits the current vehicles," said Al Adams, GM's electrical architecture and technology director.
Adams points out that the new The Electronic Platform can handle processing up to 4.5TB per. hour. A feature of the new electronic platform supports much higher bandwidth, meaning component connections of 100Mb / s, 1Gb / s and 10Gb / s. Some of it will be useful for the inclusion of advanced driver assistance systems (ADAS), and Adams said that The new electronic architecture will accelerate the spread of GM's impressive "Super Cruise" package help package across the automaker's lineup. It will also allow for higher resolution displays within the vehicle, whether it be the main display in front of a driver or HD infotainment screen for the passengers.
The system is designed with updates on the air in mind, an often requested feature now that Tesla has proven the idea. "Almost all modules on the system have the ability to be OTA updated," Adams explained. "The interface is much like a smartphone and allows us to change the character of the vehicle."
Yes, they were thinking of hackers
This audience will especially be pleased to hear that GM claims cyber security has been baked from Start. "Being cybersecure is essential for GM and a prerequisite for entering that space. We have benchmarked against the defense and aviation sector," Adam told me. In fact, the company has taken a rather proactive approach to cyber security; In addition to an internal red team, it also uses third-party pen testers and the Hacker One community to find software utilization, and setting these exploits is the same priority as any other safety-related issue with a vehicle. "For example, the new platform includes message authentication. When different car modules communicate, the receiver and transmitter have a security handshake applied to all security data. Before using data from the transmission module, each page performs an authentication handshake," says Adams.
"The critical role of software and its importance to our vehicles, both now and in the future, cannot be overstated," said GM President Mark Reuss in a statement. "Our new digital vehicle platform and its possible successors will support all of our future innovations across a range of technological advances, including EV's and enhanced automated driving."
The new electronic platform debuts in the new Cadillac CT5 sedan, which enters production this year and will be found in all new GM vehicles ahead. In addition, the current GM vehicle lines that go through a major midlife update – which usually occurs after a car has been on sale for about four years – must also receive the upgraded electronics.
