Abstract
Increasing levels of electrification and automated driving systems are resulting in the replacement and augmentation of vehicle functions with electrically controlled e-motors. These ‘smart actuators’ are increasingly complex, incorporating complex functional safety solutions, cyber security, and performance algorithms. They are increasingly developed using digital twin simulations to intensive automotive standards such as ASPICE, ISO26262 and AUTOSAR. This requires high development effort across multiple engineering disciplines.
Although the power, safety integrity and physical implementation of these smart actuators vary widely, they can be built from a limited sub-set of functional architectures. To exploit this similarity the ZF reusable foundation architecture ecosystem presented in this paper allows new product lines to build on the development effort of previous products. This ecosystem includes functional safety, systems architecture, digital twin models, test-cases, electronic circuit libraries and software components. As a result, ZF has significantly reduced the development effort across a wide range of smart actuator product-lines.
