Infineon Technologies and TTTech Auto have released the second generation of their fully integrated automotive-grade safety solution for automated driving use cases. It is based on Infineon’s AURIX TC397XM microcontroller and TTTech Auto’s MotionWise safety software platform. It delivers full support and scalability for level 2+ solutions up to the advanced levels 4 and 5 of automated driving. It helps embedded systems developers achieve faster time-to-market, improved software integration and validation thus reducing overall cost.
The first generation of Infineon’s AURIX microcontroller and TTTech Auto’s safety software platform MotionWise are integral part of zFAS, Audi’s centerpiece for piloted driving, that premiered in the Audi A8. TTTech Auto optimized its series-proven product MotionWise for the new and even more powerful second generation of Infineon’s AURIX microcontroller called TC397XM. The MotionWise safety software platform and underlying hardware are powerful enough to match the requirements of up to level 5 automated driving functions.
Residing on an ASIL-D safety hardware, the second generation of the solution is optimized for safety-critical applications. It is offering an increased ISO 26262 ASIL-D computing performance capability, a richer set of peripherals and advanced security measures. MotionWise enables fail-operational performance, freedom from interference and safety by design with highest ASIL levels for the whole platform. Each application hosted by MotionWise will run encapsulated from its peers, resulting in a safe environment where applications with different safety and real-time requirements can coexist and interact. This allows for seamless integration of applications.
Both companies gained extensive experience through close collaboration with key automotive industry players in long-term series production projects. As a key-component in more than 25 car models with production start since 2017, the first generation of this solution creates valuable synergies for series production. Several customers have already evaluated the second generation of this software/hardware combination and decided to use it in their ADAS series production programs with start of production in 2019.

NXP Semiconductors has announced a new family of high-performance safe microprocessors to control vehicle dynamics in next-generation electric and autonomous vehicles. The new NXP S32S microprocessors will manage the systems that accelerate, brake and steer vehicles safely, whether under the direct control of a driver or an autonomous vehicle’s control.
NXP is addressing the needs of carmakers developing future autonomous and hybrid electric vehicles with newly available 800 MHz MCU/MPUs. The first of the new S32 product lines, the S32S microprocessor offers the highest performance ASIL D capability available today, according to NXP.
The NXP S32S processors use an array of the new Arm Cortex-R52 cores, which integrate the highest level of safety features of any Arm processor. The array offers four fully independent ASIL D capable processing paths to support parallel safe computing. In addition, the S32S architecture supports a new “fail availability” capability allowing the device to continue to operate after detecting and isolating a failure—a critical capability for future autonomous applications.
NXP has partnered with OpenSynergy to develop a fully featured, real-time hypervisor supporting the NXP S32S products. OpenSynergy’s COQOS Micro SDK is one of the first hypervisor platforms that takes advantage of the Arm Cortex-R52’s special hardware features. It enables the integration of multiple real-time operating systems onto microcontrollers requiring high levels of safety (up to ISO26262 ASIL D). Multiple vendor independent OS/stacks can also run on a single microcontroller. COQOS Micro SDK provides secure, safe and fast context switching ahead of today’s software-only solutions in traditional microcontrollers.

Infineon Technologies has announced that it supplies key components for the Audi A8, the first series production car featuring level 3 automated driving. The ability of cars to self-drive is split into a number of different levels: With level 3, drivers can temporarily take their hands off the steering wheel under certain conditions. The Audi A8 allows this when parking and exiting, in slow-moving traffic or in traffic congestion. Using microelectronics from Infineon Technologies, a car can take over in this kind of driving situation.
Various types of chips from Infineon serve the safe automated driving in the Audi A8: sensors, microcontrollers and power semiconductors. Radar sensor chips from the RASIC family are installed in the front and corner radar. They send and receive high-frequency 77-GHz signals and forward these on to the central driver assistance controller (zFAS).
A microcontroller from the AURIX family is a key component of the zFAS for reliable automated driving. AURIX enables to secure the connection to the vehicle data bus. It assesses and prioritizes data packets and initiates their processing in the fastest possible time. For example, it initiates emergency braking based on data from radar and other sensor systems. The AURIX family of microcontrollers is especially ideal for this purpose thanks to high processing power and extensive safety features.
AURIX microcontrollers are used in several controllers in the Audi A8: On the one hand, they control the functions for the engine. On the other, they operate in the Audi AI active chassis and in the electronic chassis platform, which controls the shock absorption. The microcontrollers also support activation of the airbag.
In addition to the electronics for drive, driver assistance and chassis, other semiconductor solutions from Infineon are installed in the comfort and body electronics, such as for example LED drivers from the LITIX Basic family in the tail lights as well as bridge drivers from the Embedded Power family in the windscreen wipers.
