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
