Driver
- The driver's role in lateral and longitudinal dynamics of the vehicle
The role of the driver within the closed-loop system driver-vehicle can be viewed from two different perspectives. In the first case, the focus is on the pure controlling activity of the driver, i.e. the way he steers, accelerates, brakes, changes gears, etc. This information can be used to examine vehicle properties based on simulation, within a realistic testing scenario. At FKFS, a "virtual test driver" has been developed, which stably controls the vehicle up to the limit of adhesion and can be used, for example, for lap-time optimization.
- Driver/vehicle system simulation
On the other hand, the driver can also be seen as a sensor, who perceives the vehicle's reactions to an external disturbance as well as to his own control response. He subconsciously assesses how successful he accomplishes the manual control task on which workload this inflicts on him. Based on this principle, a method for predicting the drivers’s subjective assessment when driving under natural crosswind has been developed. Such a procedure finally allows customer satisfaction to be predicted based on simulation results alone.
