Distributed controllers
Rivian CEO RJ Scaringe discusses vehicles built around separate electronic control units for functions such as doors, climate and chassis control.
Rivian CEO RJ Scaringe discusses vehicles built around separate electronic control units for functions such as doors, climate and chassis control.
He says a modern vehicle may have many controllers running software developed by different teams, which can make coordination and debugging difficult. The exact architecture varies by vehicle.
Coordinating updates
Scaringe explains that a feature spanning several domains can require changes across suppliers and software components.
Scaringe explains that a feature spanning several domains can require changes across suppliers and software components.
He contrasts this with a more centralized or zonal design, which can simplify some updates. OTA capability and update time still depend on the actual vehicle and system.
