20090177347 | Vehicle driver assistance system and method - A driver assistance system includes a sensor for sensing the speed of a first vehicle equipped with the system, a sensor for detecting a vehicle traveling ahead, a sensor for determining the speed of the vehicle ahead, at least one driving-data sensor for sensing driving data characteristics, and an electronic controller programmed to trigger autonomous braking of the first vehicle when predetermined brake-trigger driving data exist, and to end the autonomous braking when predetermined driving data for terminating braking exist. In effecting termination of autonomous braking, the electronic controller is programmed to determine whether the sensor for detecting vehicles ahead is transmitting signals (i.e., is operational) but is not detecting any vehicle traveling ahead, and, if the sensor is operational and no vehicle traveling ahead is detected, to terminate autonomous braking when the speed of the first vehicle is less than the most recently determined speed of the vehicle ahead. | 07-09-2009 |
20120095660 | Method For Correctly Carrying Out Autonomous Emergency Braking In A Road Vehicle - The invention proposes a method for correctly carrying out autonomous emergency braking in a road vehicle (1) in order to reduce the severity of an accident, the speed of the vehicle being determined during the autonomous emergency braking. According to the method, a determination of speed which is independent of the wheel rotational speeds of the vehicle is additionally used. By this means, the vehicle speed can be determined sufficiently accurately even in the cases in which, as a result of sharp autonomous braking, the vehicle speed is higher than the wheel rotational speeds. | 04-19-2012 |

20130211621 | Vehicle Regulating System and Method for Determining Tire States - A control device for a vehicle regulating system is configured to pick up driving state measurement signals from driving state sensors of the vehicle and determine reaction properties of the vehicle wheels from the signals. The control device is configured to also pick up roadway measurement signals of a spectroscopic sensor that is aligned with a roadway surface and determine therefrom the presence and/or properties of a layer of water on the roadway surface. The control device determines tire properties of the tires on the basis of the determined reaction properties of the vehicle wheels and the roadway measurement signals. | 08-15-2013 |
20130333969 | Method for Controlling Pressure in a Vehicle and Pressure Control Device - The aim of the invention is to lower the fuel consumption of a vehicle having a pneumatic brake system during operation of the vehicle by utilizing existing components to their full capacity, thus contributing to energy conservation. The invention relates to a method for controlling pressure, wherein modes of compressed air expansion are provided: in a second compressed-air expansion mode, compressed air is channeled from a second compressed-air storage container to the compression chamber of the air compressor during expansion phases of the air compressor. In a third compressed-air expansion mode, compressed air is channeled from a third compressed-air storage container to the compression chamber of the air compressor during expansion phases of the air compressor. The invention further relates to a pressure control device. | 12-19-2013 |
20140076409 | PRESSURE CONTROL DEVICE FOR A TIRE INFLATING SYSTEM WITH A ROTARY FEEDTHROUGH, AND TIRE PRESSURE CHANGING METHOD - A pressure control device for a vehicle tire inflating system is configured to receive compressed air via a ventilating inlet, activate at least one seal for sealing an air chamber between a stator and a rotor of a rotary feedthrough via a seal actuating outlet, and ventilate a tire at a ventilating outlet pressure via a ventilating outlet and the feedthrough. A control valve is pneumatically controllable by a control pressure, the ventilating outlet being ventilated at the outlet pressure by the control valve only when the control pressure is at least a defined minimum pressure. In response to pressure build-up at the ventilating inlet at least to the minimum pressure, the control pressure and the seal actuating pressure are built up for ventilating, but build-up of the control pressure is with respect to the seal actuating pressure. Activation of a seal prior to ventilation of the ventilating outlet is possible without additional actuating channels. | 03-20-2014 |
20140132031 | Lateral Rear Spoiler Device for a Utility Vehicle or the Trailer Thereof - A rear spoiler device for a vehicle, as a utility vehicle or a trailer, includes at least one adjustable air guiding element for aerodynamically guiding air and extending the contour of the lateral region of the rear of the vehicle. The guide element is adjustable between a travel position, in which it extends rearwards in a lateral region of the rear for aerodynamically guiding air and extending the contour, and a stowed position. The air guiding element is spring pre-loaded into the extended travel position and is adjusted into the stowed position by pressing the guide element from the rear side counter against the spring pre-load. | 05-15-2014 |
20140346808 | Rear Spoiler Device for a Vehicle - A rear spoiler device for a vehicle that has a rear door includes an air guiding element configured to attach to a lateral rear zone of the vehicle. The air guiding element can be pivoted between a travel position for contour extension and aerodynamic air guidance with the rear door of the vehicle closed, and a position in which it is hinged inwards with the rear door open. To this end, the air guiding element can be received in a hinge of the rear door, and the rear spoiler device has a spring device that presses the air guiding element in the travel position against a counter-stop formed on the hinge, preferably, on a hinge plate fastened to the rear door. | 11-27-2014 |
