Previously, the only major control module that GM was able to perform OTA updates for was for the semi-autonomous Super Cruise system, explained Cadillac’s executive chief engineer Brandon Vivian in a recent interview with Automobile.
While Vivian did not elaborate on what control modules GM will be providing OTA updates for, major control modules it may want to update include those for the engine, brakes, chassis or suspension.
Electric vehicle maker Tesla made news last year after its Model 3 sedan failed to receive a recommendation from Consumer Reports due to the car’s poor braking performance. The company then did an OTA braking update, which reduced the vehicle’s stopping distance by nearly 20 feet in CR testing. The publication subsequently added the vehicle to its list of recommended vehicles.
We already knew that GM was able to offer OTA updates for the latest version of Cadillac Cue infotainment system, but this is the first we’ve heard that GM will be able to do OTA updates for other major parts of the vehicle. These updates will be done via GM’s in-car 4G LTE network.
For those who worry about the security implications of having a vehicle that’s always connected to the internet, Cadillac has an answer. Vivian said the automaker already has segment-leading security tech and plans to bring updates in the future that will bring even more improvements.
“Our next-generation electrical architecture has encryption tech that will really set us apart,” Vivian told Automobile. “We will have some upgrades and enhancements in the future that you’re going to hear about shortly.”
The 2020 Cadillac CT5 will arrive at dealers in late 2019.
