'We need the consistent use of modern software development methods'

摘要

ATZelectronics _ Functional safety is one of the central aspects of vehicle development. Classical methods of validation involve (HW) redundancy. Is this still relevant in the age of the Software-defined Car (SWdC)? SCHMIDT _ Hardware redundancy alone will not ensure functional safety in software- defined cars. Overall, the share of software in a vehicle is increasing rapidly. This development is driven in part by automated driving, a field in which functional safety in terms of software must be ensured at all costs. Software can be brought onto a higher safety level via redundancy. This is done through the use of algorithms, for example, that permanently monitor and perform plausibility checks on a vehicle’s sensor data, thus providing the ability to analyze faults. Since the environment of an automated vehicle must also be considered, ensuring functional safety has become much more difficult. The focus is moving away from the ego- vehicle toward the environment, which makes the topic extremely complex. With systems such as ESP, or in con ventional vehicles, the driver is the fallback level. With automated vehicles, the driver is replaced by algorithms.
