Process Business Segment
Guarantee safety, security, and trustworthiness throughout the life cycle of self-driving systems and MaaS, and provide technologies that can be used by on-site developers.
Products and value provided
- Support on-site developers to fill the gaps between the ISO 26262 and other international standards and real-world solutions
- Provide support for creating deliverables compliant with functional safety, security, and other standards, and research the latest technology trends
- Provide support to improve the development process based on the MBSE concept
- Provide support to train customers’ standardization personnel and on-site developers
- Provide a process architecture for safety, security, and trustworthiness throughout the life cycle of self-driving systems and MaaS (provide the OTSL Method)
- Develop and deploy the methodology of system safety, trustworthiness, etc., including reasons for derivation
Track record examples
- Vehicle modeling and architecture design based on MBSE, and development and simulation based on MBD
- Safety verification and safety analysis for self-driving systems (create STAMP/STPA cases)
- Support for functional safety system design for electrically driven vehicles, ADAS power control, etc
- Support for building an ECU system-level functional safety development process
- Support for designing functional safety for a self-driving system
- Support for building the security process to develop vehicles
- Creating a catalog of fundamental security technologies to develop vehicles
Support On-site Developers
- On-site issues
- Development cost increase due to a lack of development process for verifying safe and safety
- Explanation cost increase due to the inability to show verification points in the development process
- Design do-over due to verification by trial and error
- Upward changes of standards (functional safety/security/SOTIF）
- Proposals and implementation by OTSL
- Present the process that guarantees safety and security
- Support for creating deliverables that keep record of design thinking
- Support for tracing the verification method
- Research on trends/creating a catalog of trends inside and outside Japan
- Effects obtained
- Development man-hour reduction
- Explanation time reduction
- Design do-over reduction
OTSL Method
Provide the methodology to systematically determine the details of the life cycle process (planning to discard) of self-driving systems and MaaS
