D-AWSIM: Distributed Autonomous Driving Simulator for Dynamic Map Generation Framework
Shunsuke Ito, Chaoran Zhao, Ryo Okamura +1
Autonomous driving systems have achieved significant advances, and full autonomy within defined operational design domains near practical deployment. Expanding these domains requir…
Work in Progress: Middleware-Transparent Callback Enforcement in Commoditized Component-Oriented Real-time Systems
Takahiro Ishikawa-Aso, Atsushi Yano, Takuya Azumi +1
Real-time scheduling in commoditized component-oriented real-time systems, such as ROS 2 systems on Linux, has been studied under nested scheduling: OS thread scheduling and middle…
AUTOSAR AP and ROS 2 Collaboration Framework
Ryudai Iwakami, Bo Peng, Hiroyuki Hanyu +2
The field of autonomous vehicle research is advancing rapidly, necessitating platforms that meet real-time performance, safety, and security requirements for practical deployment.…
Generalized Inequality-based Approach for Probabilistic WCET Estimation
Hayate Toba, Atsushi Yano, Takuya Azumi
Estimating the probabilistic Worst-Case Execution Time (pWCET) is essential for ensuring the timing correctness of real-time applications, such as in robot IoT systems and autonomo…
TECS/Rust: Memory-safe Component Framework for Embedded Systems
Nao Yoshimura, Hiroshi Oyama, Takuya Azumi
As embedded systems grow in complexity and scale due to increased functional diversity, component-based development (CBD) emerges as a solution to streamline their architecture and…
ipc_shared_ptr: A Publish/Subscribe-Aware Smart Pointer for Cross-Process Object Lifetime Management
Takahiro Ishikawa-Aso, Atsushi Yano, Koichi Imai +2
True zero-copy Inter-Process Communication (IPC) in publish/subscribe (pub/sub) middleware such as Robot Operating System 2 (ROS 2) requires subscribers to reference message object…
