Our company leverages extensive knowledge of a wide range of in-vehicle systems to provide engineering services for vehicle development operations aimed at automotive OEMs. Based on our rich development experience and know-how in OEMs, we enable efficiency, automation, and quality assurance tailored to the vehicle development processes and stages. Specifically, in the development of rear-side warning support systems, we plan the necessary system development schedule based on the predetermined development timeline for each vehicle model and coordinate with relevant departments and affiliated companies. In the event of any inconsistencies or issues, we conduct prompt and optimal adjustments to ensure the smooth progress of the overall vehicle development. Additionally, we propose function selection and parameter settings that comply with the specifications for each vehicle (such as powertrain type, brakes, drive system, and destination). If integration with other systems is required, we also handle specification requests for ECUs and other components. Furthermore, during system evaluation corresponding to the phased completion of the vehicle, we conduct performance and operation checks to ensure compliance with standards and make specification modifications as necessary. Including coordination and negotiation with stakeholders, we support your in-vehicle system development.

Our company provides engineering services for meter development aimed at automotive OEMs. We promote requirements definition and specification formulation with an eye toward multifunctionality and multilingual support for the next generation. We accurately extract user-operable items, various switches, and all options at each hierarchy from the requirement specifications indicated by each ECU, organizing the requirements into a "customization list." We carefully organize a variety of use cases and produce clear documentation that enables a smooth handover to designers and implementation departments. This significantly reduces the risks of requirement omissions, overlaps, and rework in the development of multifunctional in-vehicle meters. We also support the creation of a "font specification list" that details font types, sizes, and display patterns across dozens of languages. By collaborating with designers and implementation departments, we build an optimal font environment for each language used. (Since designers are also in-house staff, closer collaboration is possible.) Through reliable requirements definition and specification management, we strongly support your in-vehicle meter development.
