TTTech Automotive selected to supply ECUs for Aptera US-based e-car manufacturer Aptera will use TTTech Automotive's TTC 90 High Safety Controller in its ambitious Aptera 2e electric vehicle.

As a result of detailed analyses during the past year, the e-car vendor to-be have entered strategic relationships with suppliers of material, equipment, systems and components for its ambitious Aptera 2e e-car design project. In this context, TTTech Automotive will provide its expertise in the field of functional safety by supplying its TTC 90 High Safety Controller along with the respective software. “By teaming with innovative partners such as TTTech Automotive, bringing years of high-level experience to our company, we are confident to assure the 2e is remarkably engineered, ultra-efficient and safe,” said Aptera CEO Paul Wilbur.

The safety controller provided by TTTech is equipped with a main CPU running user applications and a smaller diagnostic CPU which monitors the main CPU and all safety-critical inputs and outputs. In case an error is detected, an internal switch opens, disconnecting all output stages from power supply and transferring the vehicle into a safe state, thus preventing uncontrolled movements of the vehicle.

The main CPU in the controller is a 16/32-bit Infineon XC2287 controller while for the diagnostic CPU a Freescale HC 908 is used.

The Aptera 2e is one of the candidates for the coveted Progressive Insurance Automotive X-Prize. It also was named one of the “Best Inventions of 2008” by the Time magazine.
