The simulator offers an excellent opportunity to investigate longitudinal dynamics in a reproducible way. The overall mechatronic concept comprises three degrees of freedom and four actuators. A linear drive accelerates the entire assembly translatorily along a guiding track with a length of 10 m. Through combined movements, a lifting actuator in the rear area and two parallel hollow spindle motors in the front area allow the driver's cabin to rotate around a variable point. Due to the combined longitudinal and rotational movement, stationary accelerations of more than 3 m/s² and total accelerations of more than 5 m/s² can be simulated. In addition to the use of new technologies such as head-mounted displays, the test bench concept is characterized by its simple, compact and cost-effective design.
Multimodal studies can be used to identify specific factors influencing the perception of vehicle longitudinal dynamics. The aim is to reproduce the real driving behaviour as accurately as possible in order to determine perceptual thresholds, for example, with the help of extensive studies of test persons or to be able to carry out evaluations of longitudinal dynamic driving manoeuvres such as launching or gear shifts. With the Driveception, acceleration profiles of future drive concepts, for example, can be subjectively evaluated by test persons in early development phases.
