Some passenger cars are equipped with rear-axle steering to improve vehicle dynamics.
Rear-axle steering involves turning the wheels on the rear axle, which has a direct effect on the vehicle dynamics. This is an advantage in many different driving situations. The ability to change the toe angle of the rear wheels provides the driver with different steering functions:
Similar to with front-wheel steering, hydraulic or electromechanical actuators can also be used to carry out the corresponding steering commands. There are two different variants that can be used, depending on the requirement and available installation space:
Die Hinterachslenkung trägt aktiv zur Fahrsicherheit bei: In engen Kurven verkleinert sich der Wendekreis, bei höheren Geschwindigkeiten wird die Fahrstabilität erhöht.
