The Automotive Engineering Department of the Darmstadt University of Technology takes part in the Special Project 241 'New Integrated Mechanic-Electronic Solutions for Mechanical Engineering Systems' of the German Research Foundation (DFG: Deutsche Forschungsgemeinschaft) with the subjects: Tire with an Integrated Sensor (A3), Adaptive Wheel Suspension (A7) and Electrically Actuated Wheel Brake (B6). With the ,,Darmstadt Tire Sensor' the deformation of a tread element in the tire contact area in x, y and z-direction can be measured in the rotating tire without affecting its performance characteristics. This allows not only to calculate the local individual forces, but also the global forces transmitted by the tire as an integral of the local forces. The tread element deformation is measured by the sensor as a position change of a magnet relative to four crosswisely arranged Hall sensors. The movements in x, y and z-direction can be resolved by the interconnection of the four elements. The evaluation and on-line assessment of the characteristic signal patterns of the tread element deformation achieved during tire rotation yield information on: coefficient of friction, tire pressure, wheel load, braking and acceleration forces, lateral forces, risk of hydroplaning, tire temperature. A mechatronic wheel brake has being investigated and the current research topics are both the improvement of the efficiency of several components and the use of the vehicle's kinetic energy to actuate the brakes. An actuator was developed to substitute a common rubber-metal element to link the wheel suspension to the body. The properties of the actuator with regard to stiffness, damping capacity and kinematics are variable in a wide range, i.e. they may be adjusted to the current driving situation. However, safety has priority over riding comfort.
