The invention relates to a sensor assembly for recognizing a state of a roadway, including a sensor device, which is adapted to capture an impact of water on a wheel arch lining of a motor vehicle during a travel of the motor vehicle on the roadway, and including a control device for recognizing the state of the roadway based on the impact of the water captured by means of the sensor device, wherein the sensor device includes an ultrasonic sensor, which is adapted to receive an ultrasonic signal and which is additionally adapted to capture the impact of the water on the wheel arch lining.

Sensor arrangement for detecting a state of a roadway using an ultrasonic sensor, a driver assistance system, a motor vehicle, and an associated method

A method is provided for semi-automatically adjusting a chassis of a vehicle. The vehicle () assesses a state of the road by means of a sensor system of the vehicle and transmits the state of the road to a central server. A further vehicle () interrogates the state of the road from the server and recommends adjustment of the chassis as a function of the interrogated state of the road. The invention also relates to a device for carrying out such a method.

Method and device for automatically or semi-automatically adjusting a chassis

An indicating device for a motor vehicle and an operating method are provided. The motor vehicle includes a drive train with at least one drive unit. The indicating device shows in a differentiable manner to the driver the drive states of accelerating, unpowered driving (coasting) and decelerating using the drive train, and at a minimum signals to the driver when the coasting state exists so as to permit the driver to optimize efficient use of the vehicle.

Motor vehicle, indicating device and operating method

This invention provides an arrangement which compensates for the dynamic effects of cross winds on the steering of a vehicle. A single differential pressure sensor is connected with pressure measuring points arranged symmetrically on the forward portion of the vehicle body. The differential pressure detected by the pressure sensor is used to determine the yaw angle velocity and acceleration caused by the force of the cross wind on the vehicle body, which information is provided to a steering control element that adjusts the steering angle of the vehicle to reduce the yaw angle to approach zero.

Method and apparatus for minimizing effects of cross wind on vehicle

A sensor arrangement for detecting the influence of cross wind on the handling of a motor vehicle comprising pressure measuring points situated on opposite sides of the vehicle for the measuring of the air pressure existing in the area of the outer skin of the vehicle body. The pressure measuring points are constructed as bores in the outer skin of the vehicle body. A differential pressure sensor, which detects the differential pressure (Dp) between two vehicle sides, is arranged centrally between two pressure measuring points, and is connected with the two bores by way of hoses or lines which, if possible, should have the same length. For detecting the vehicle's entry into and emergence from a cross wind gust, the sensor filters the detected values of the wind cross force by means of a low pass filter and compares them with the filtered values that were detected immediately before. When the difference between the amounts of the filtered values rises, entry into a cross wind gust is recognized, and when the values fall, emergence form a cross wind gust is recognized.
