Modular test bench for complete vehicles ready to drive

摘要

In order to provide a highly dynamic test rig arrangement with which a simulation of realistic traffic scenarios and thus a test of driver assistance systems of a complete vehicle ready to drive (3) is made possible according to the invention on a vehicle test bench (1) a steering force module (2) is provided, which consists of a first body (21 ) and a relative thereto displaceable lateral force actuator (20), wherein the transverse force actuator (20) via a first mechanical interface (M1) with an unhooked tie rod (300) of the steering system (30) is connectable. The first base body (21) is mechanically connectable to a first fixed mounting point (P1), wherein a transverse force (Q) by a relative displacement of the transverse force actuator (20) to the first base body (21) is generated, whereby the transverse force (Q) to the Steering system (30) can be applied. Furthermore, a drive train module (4) is present which consists of a second base body (41) and a drive actuator (40) which can be rotated relative thereto, the drive actuator (40) being non-rotatably connected via a second mechanical interface (M2) to a drive axle (310) of the Drive train (31) is connectable and the second base body (41) with a second fixed mounting point (M2) is mechanically connectable, one of the transverse force (Q) independent torque (D) by a relative rotation of the drive actuator (40) to the second body (41) is generated, whereby the torque (D) to the drive axle (310) can be applied. The test rig assembly may be used to provide an integration, calibration, and test environment for driver assistance systems of a complete vehicle (3) that is ready to drive.
