Instrumented steering wheel for accurate ADAS development
The knowledge of the forces exerted by each hand of the driver at the steering wheel is useful for a better understanding of the driver steering action. This information is needed while developing haptic steering wheels useful for tuning Advanced Driver Assistance Systems (ADAS). The actual forces applied by the driver’s hands can be measured by means of a new Instrumented Steering Wheel (ISW), that, by using two six axis load cells, can measure the three force components and the three moment components exerted by the two hands, separately. Additionally, the instrumented steering wheel allows to measure the grip force, defined as the holding force applied by each hand on the handle. A full compensation of the inertia forces due to the vehicle acceleration guarantees an extremely high level of accuracy in the measure of the forces exerted by the driver. The resolution is just 0.1 N. The ISW has been already used for a couple of ADAS activities.
