AMETIST Case Study 3 4 FV/SLD-Kowalewski, September 2002 Challenges Traditional development: Each application has dedicated sensors, actuators, ECU, Software and HMI. No longer possible due to number of applications, cost, space. Platform development needed: –Integration of applications (services) –Sharing of distributed resources (sensors, ECU, data) –Different variants Real-time requirements for single applications must be met by integrated system Model-based analysis necessary

AMETIST Case Study 3 5 FV/SLD-Kowalewski, September 2002 CPS platform Applications: Pre-Crash and Parking Assistance One ECU per Sensor and one central ECU per cluster Two sensor modes: –D (distance) mode: 1 - 7 m (D 1 ), 1 - 2 m (D 2 ) –C v (closing velocity): 0.69 - 1.41 m D 2 is for recovery from precrash situation Hard response time requirements, in particular lead time for precrash indication Different HW and OS platforms: OSEK / dedicated scheduler

AMETIST Case Study 3 11 FV/SLD-Kowalewski, September 2002 Open problems Current situation: –No complete prototype existing; only parts can be tested. –Timing still based on estimations and assumptions. –Any results on the relation between environment properties and timing requirements are welcome. Examples: –Implications for object numbers/velocities/distances from the lead time requirements for Pre-Set and Pre-Fire? –How robust is the 15 ms frequency (in case of delays, or additional components)? –Optimal assignment to OSEK tasks?

AMETIST Case Study 3 12 FV/SLD-Kowalewski, September 2002 Future of SRR development at Bosch unclear Business unit decided to put SRR component development on hold. Possible decisions in future: –Buy SRR components and sell systems –Replace SRR (24 GHZ) by LRR (77 GHz) –Start SRR component development again Consequence: platform development currently in waiting loop
