Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Anpassung der Dämpferkraft verstellbarer Dämpfer in Kraftfahrzeugen, insbesondere in Nutzfahrzeugen mit semiaktiven Dämpfersystemen. Die Anpassung der Dämpferkraft erfolgt in Abhängigkeit von mindestens einer Straßeninformation, die unter Verwendung der Ausgabedaten mindestens einer Kamera ermittelt wird und die ein Objekt und/oder eine Änderung der Straßenoberfläche in einem in Fahrtrichtung des Kraftfahrzeugs vorausliegenden Straßensegment betreffen. Gemäß dem Verfahren wird ferner eine Distanzinformation, die eine Position, einen Abstand und/oder eine Zeit bis zum Erreichen des Objekts und/oder der Änderung der Straßenoberfläche angibt, in Abhängigkeit von einem Nickwinkel des Fahrzeugaufbaus bezüglich einer Aufbaulängsachse bestimmt, wobei der Nickwinkel aus den Ausgabesignalen mindestens eines Federwegsensors einer Federungsrichtung des Fahrwerks ermittelt wird.
摘要:
A method for detecting a misalignment of a vehicle chassis by using image data of a vehicle camera. Image data is received from the vehicle camera and a horizon position and a position of a camera axis is identified. A distance between the horizon and the position of the camera axis is derived and compared with a previously calibrated distance. If a misalignment value, which is derived from the difference, exceeds a first pre-determined threshold, a corresponding output signal is generated.

摘要:
A method for improving accuracy of vehicle position determination, comprising: determining an initial vehicle position estimate based on GPS data, recording a sequence of sensor data from a sensor located with the vehicle, and refining the initial vehicle position estimate by performing pattern matching with a pattern matching system that looks for the presence of a known sequence of data in the recorded sequence of sensor data.
摘要:
The invention relates to a method for controlling an electric compressor of a pneumatic suspension system which can be switched on and off according to requirements. The temperature of the compressor is calculated according to a temperature model and the compressor is switched on or off in accordance with the calculated temperature. Said control device takes into account the air pressure surrounding the vehicle as an input variable for calculating the temperature of the compressor in accordance with the temperature model and the parameters of the temperature model are adapted in accordance with said air pressure.
摘要:
A vehicle (15), such as a lorry or a bus, includes compressed air consuming devices (13) and a power driven compressor (10) to deliver compressed air to at least one storage tank (11, 12). A control device (14) controls the operation of the compressor so as to maintain the air pressure in the tank at a desired pressure level sufficient to operate the air consuming devices, such as a braking system and a suspension system, when needed. The air pressure is usually maintained substantially at a predetermined first elevated level or value. However, based on signals from position identification means (17, 18), such as a global navigation system or other external or internal position identification sources the control device controls the operation of the compressor (10) so as to change the pressure of the air in the storage tank (11,12) to a predetermined second elevated level or value substantially different from said first level or value in response to receiving from the position identification means an indication to the effect that the vehicle (15) is approaching or has arrived at one (16,19) of a plurality of predetermined positions and/or positions fulfilling predetermined criteria.
