Opening Doors toNew Possibilities
CHANGING MOBILITY
Mobility trends are changing. Vehicles were once exclusively owned and operated by individuals. Today, shared mobility service offerings continue to rise with users embracing the convenience of ride sharing, car sharing and new models for delivery of transportation services. These changes in mobility trends are driving new ways for users to access and engage with their vehicle. At ADAC, we’re developing next generation technologies that align with these trends including phone-as-a-key and other sensing solutions – all with the objective to improve end-user experience.
CONCEPT TO PRODUCTION
ADAC makes ‘what-if’ a reality.
Our process-driven design approach allows ADAC to quickly turn thoughts from a sketch into concepts that enable our customers to challenge design norms, advance the integration of electronics and elevate user experience. Using rendering, CAD modeling and in-house 3D printing we turn ideas into prototypes in hours rather than days or weeks.
Human Centered Design
Optimized user experience demands meticulous attention to detail. Our products combine mechatronic elements with cosmetic finishes that enhance vehicle styling and make users’ lives easier.
By studying behaviors and developing technologies to meet the most stringent specifications, ADAC is delivering products that create seamless experiences. New innovations like hands-free gesture access will permanently shift expectations regarding the way users enter their vehicles today and define access for new mobility solutions.
