A senior car is an electric wheelchair mainly used by elderly people. Senior cars are treated the same as pedestrians under the Road Traffic Act, so no license is required. As for the operation method of the senior car, the direction is decided by the steering wheel, the speed is set by the dial, and the vehicle can be driven by using the accelerator lever. However, senior cars currently on the market have low response performance to driving commands from drivers, and due to insufficient safety confirmation when crossing the road by senior cars, contact accidents with pedestrians, bicycles, and automobiles occur frequently. In this paper, using SIMULINK model of a senior car, we compared the conventional acceleration / deceleration method and the advanced S-shaped acceleration / deceleration method on the ride quality. Simulation results show that the advanced S-shaped acceleration / deceleration method is a well-balanced method.
