Woven by Toyota is enabling Toyota's once-in-a-century transformation into a mobility company.
Inspired by a legacy of innovating for the benefit of others, our mission is to challenge the current state of mobility through human-centric innovation — expanding what "mobility" means and how it serves society.
Our work centers on four pillars: AD/ADAS, our autonomous driving and advanced driver assist technologies; Arene, our software development platform for software-defined vehicles; Woven City, a test course for mobility; and Cloud & AI, the digital infrastructure powering our collaborative foundation.
Business-critical functions empower these teams to execute, and together, we're working toward one bold goal: a world with zero accidents and enhanced well-being for all.
=========================================================================TEAM
Toyota is redefining what it means to move . We're challenging the current state of mobility by enhancing the movement of people, goods, information and energy.
Centered around three core concepts - A Living Laboratory, Human-Centered, and Ever Evolving City - Woven City serves as a test course for mobility to fulfill our purpose of well-being for all.
We do this by bringing together a diverse community of people with a shared passion for the future of mobility to co-create, develop and refine innovative products and services.
This cross-section of social infrastructure, mobility, and people provides a unique opportunity for inventors, residents and visitors to interact seamlessly with new technologies throughout daily life in an environment that emulates a real city.
We are researching and developing new remote services that apply our proprietary XR technology.
Our mission is to develop products reflecting the results of this research with our partner company and provide them to Woven City and others.
