E-Motor
• Electric vehicles are „by-wire“ (safety-relevant system)
• Unintended acceleration or deceleration to be avoided!
• TTTech‘s ESU is a safe guarding unit to control thisbehavior
• Torque supervision by voltage and current measurements, switch off in case of error
• Retrofit to existing powertrain concepts,or customized integration with inverter / VCU
• Certified for SIL 2-3)
• Prototypes available now, SOP in Q1/2011

ASIL Decomposition
The safety elements …• … detect and handle possible faults in the Basic SW• … are independent elements in the system with specific functionality
(addressing the detection and mitigation of faults in the Basic SW) • … are developed according to the required ASIL• … are developed as „Safety Element out of Context“ and have to be
integrated according to their „Safety Manual“
