Therefore, the spatial position of the seat, pedals, and headrest can be digitally adjusted according to the driver's various habits of holding the steering wheel and the driver's sitting posture in the seat. The position of each component is adjusted according to the driver's own situation. Then, the relevant adjustment data is recorded, repeated experiments are conducted, and continuous optimization is carried out to finally obtain cockpit data that is more suitable for the driver, providing a reference standard for cockpit design.
