Publication number: 20110132080Abstract: An apparatus ascertains a contact area length of a vehicle tire. The apparatus has a transmission unit which has a resonator and which is set up to transmit a sensor signal at a defined frequency. A change in the frequency of the sensor signal on the basis of mechanical excitation of the resonator is indicative of a contact area length for the vehicle tire. Furthermore, the apparatus has a contact area length ascertainment unit which is set up to receive the sensor signal and to take the change in the frequency of the sensor signal as a basis for ascertaining the contact area length of the vehicle tire.Type: ApplicationFiled: December 9, 2010Publication date: June 9, 2011Applicants: CONTINENTAL AUTOMOTIVE GMBH, CONTINENTAL AKTIENGESELLSCHAFTInventors: GUIDO GRANDE, MARIO HASELSTEINER, OTTO MÜLLER

Patent number: 7937205Abstract: In order to ensure problem-free operation of a vehicle when a wedge of material is formed between the roadway and the vehicle, a method for controlling the functions of an electronic driving stability program automatically activates or deactivates the driving stability program of the vehicle according to the respective operational situation of the motor vehicle. The driving stability program is automatically deactivated when the vehicle drives onto a wedge of material on the roadway. A determination whether the vehicle drives onto a wedge of material on the roadway is made by means of the air springs of the vehicle and associated distance sensor and/or pressure sensors.Type: GrantFiled: November 4, 2004Date of Patent: May 3, 2011Assignee: Continental AktiengesellschaftInventors: Marc Nettelmann, Jörg Grotendorst

Publication number: 20110052422Abstract: In a method for controlling the operation of a compressor, the compressor is switched off by a controller in order to prevent thermal damage if an estimated temperature value calculated by the controller exceeds an upper threshold value. The controller calculates a cooling function as a state variable utilizing the estimated temperature value, the cooling function representing the chronological course of the cooling of the compressor. The controller determines the cooling function based on at least one first and one second estimated temperature value which are associated with points of the compressor that are at spatial distances to each other. The calculation of the cooling function is based on a temperature difference between the first and second estimated temperature values.Type: ApplicationFiled: November 10, 2010Publication date: March 3, 2011Applicant: CONTINENTAL AKTIENGESELLSCHAFTInventor: MAREK ENGELHARDT

Patent number: 7881840Abstract: Disclosed is a level control system in which the operational readiness of the compressor (2) is tested by connecting the pressure sensor (10) to the output (6) of the compressor (2) via a compressed-air sensor line (8). All other compressed-air lines that are connected to the output (6) of the compressor (2) are locked by shutting directional control valves (201 to 20d and 30). The compressor (2) is then switched on and it is tested how rapidly the pressure increases on the pressure sensor (10). If the increase per interval exceeds a defined threshold value, the compressor is operationally ready.Type: GrantFiled: February 21, 2006Date of Patent: February 1, 2011Assignees: Continental Aktiengesellschaft, Continental Teves AG & Co.

Publication number: 20100303637Abstract: A method controls a compressor for delivering a pressure medium into a pressure medium system, for example an air suspension system in a motor vehicle. In the method, the delivery of the pressure medium can be switched on and off as a function of a temperature signal by the compressor temperature being measured by a temperature sensor which is arranged on the compressor and the switching on and off of the compressor is controlled by an electronic control unit. The switching-on time duration and/or the switching-off time duration or the switching-off and/or the switching-on temperature are/is determined from the rise of the compressor temperature which is measured at short time intervals.Type: ApplicationFiled: June 21, 2010Publication date: December 2, 2010Applicant: CONTINENTAL AKTIENGESELLSCHAFTInventor: Marek Engelhardt
