Innovating the Future of Entry: Development of a Novel Vehicle Entry & Exit System for Reduced Mobility Drivers

This project addresses the need for improved vehicle ingress and egress solutions for individuals with reduced mobility, particularly elderly drivers seeking to maintain their independence. This group is often limited by conventional hinged doors, which are inoperable or severely restricted in tight spaces, such as when parking near another car. Therefore, our goal was to develop a solution that enables intuitive car entry in all situations, ensuring the process is effortless and dignified for those with reduced mobility. In collaboration with the Volkswagen Innovation and Engineering Center California, Team VOSSwagen developed a mechanically operated, multi-axis door system. We designed this system to maximize entrance volume while functioning within a standard 9ft by 18ft parking space. Operating similarly to a van sliding door, but for the front passengers, the final system integrates four coordinated subsystems: a "Push Pull" linear actuator, a "Pivot Arm", a "Chain & Sprocket Mechanism", and an “Alignment Actuator.” We constructed a full-scale prototype using a wooden vehicle frame and 80/20 structural components to replicate realistic vehicle geometry and validate mechanical feasibility. During experimental validation, we focused on three engineering goals. Functional calculations within a standard parking space confirmed successful operation in tight parking spots. Geometric Analysis of the system demonstrated a 253% increase in usable entrance volume in tight spaces compared to a traditional hinged door. Finally, the opening sequence finished in 11 seconds, failing to meet the sub-five-second requirement. These results demonstrate the feasibility and utility of a van-style door for the driver, as the system enhances accessibility while fitting into the standard car geometry. Ultimately, this work established a validated proof of concept for a next-generation vehicle entry architecture aligned with Volkswagen’s vision for inclusive mobility.
