Patent number: 7502704Abstract: A method for monitoring the pressure of motor vehicle tires is provided. In the method, a tire pressure value of the tire filling pressure and a tire temperature value are determined. While taking into account the tire temperature value, the determined tire pressure value is compared with a stored nominal value and the comparison result is used to determine whether the motor vehicle tire is at an incorrect tire pressure, in particular, a low tire pressure. If the tire pressure is incorrect when a characteristic change in the tire pressure occurs, the stored nominal value is replaced by a new nominal value, and the comparison result is used to determine the new nominal value of the determined tire pressure value.Type: GrantFiled: December 11, 2004Date of Patent: March 10, 2009Assignee: Daimler AGInventors: Joerg Burghardt, Wolfgang Kiesewetter, Jan Kipping, Frank Schlosser

Patent number: 6824227Abstract: A brake system for a vehicle is equipped with a brake servo assistance unit for the automatic generation of brake force and with at least one sensor for the generation of a measuring signal. This signal represents an activity on the part of the driver and can be fed to a brake pressure control unit. An activation control signal for the actuation of the brake servo assistance unit can be generated should the measuring signal lie within an activation value range. In order to improve operating reliability, at least two sensors are provided for measurement of an activity on the part of the driver, and an activation control signal can be generated should the measuring signals from the sensors each exceed a reference value.Type: GrantFiled: May 22, 2002Date of Patent: November 30, 2004Assignee: DaimlerChrysler AGInventors: Wolfgang Kiesewetter, Bernd Knoff, Manfred Steiner

Patent number: 6470986Abstract: A method for determining an initiation threshold value for an automatic braking process, in which an automatic braking process is used and a brake pressure is produced which is greater than the brake pressure which corresponds to the operation of the brake pedal by the driver. Short distances between vehicles increase the risk of accidents. If a driver operates the brakes when there is a short distance between the vehicle and the preceding vehicle, in the vast majority of cases, the driver of the following vehicle is often required to perform an emergency braking due to the short distance between the vehicles. To improve the safety of vehicles, an emergency braking is performed, as quickly as possible, when the distance between vehicles is short. This emergency braking, within what is physically possible, ensures rapid deceleration of the vehicle and thus helps to avoid rear-impact accidents.Type: GrantFiled: May 25, 2001Date of Patent: October 29, 2002Assignee: DaimlerChrysler AGInventors: Alexander Fuchs, Carsten Lauer, Manfred Steiner, Lorenz Maack, Eberhard Pfeifle, Bernd Knoff, Wolfgang Kiesewetter

Patent number: 6342832Abstract: A process and device are disclosed for preventing a vehicle from colliding with an obstacle during parking. The object of the invention is therefore to ensure that a collision can be reliably avoided without any additional intervention of the drive. In a device with at least one sensor for generating signals which represent the distance between the vehicle and an obstacle, the signals are processed in an evaluation unit. When at least one distance-representing signal falls below a limit value, a warning signal is generated. This warning signal drives a control valve which generates a pressure difference between the working chamber and the vacuum chamber in a brake booster when the warning signal is generated. This pressure difference causes the braking pressure to rise in the wheel brake cylinder and therefore slows the vehicle down to a standstill.Type: GrantFiled: June 22, 2000Date of Patent: January 29, 2002Assignee: DaimlerChrysler AGInventors: Alexander Fuchs, Wolfgang Kiesewetter, Bernd Knoff, Carsten Lauer, Lorenz Maack, Eberhard Pfeifle, Manfred Steiner

Patent number: 5836660Abstract: The invention provides a method for determining a threshold value for triggering an automatic brake application wherein a braking pressure greater than that corresponding to the position of the brake pedal is developed when the actuating speed of the brake pedal exceeds a triggering threshold value determined from a preset threshold value and a vehicle-specific correction factor. According to the invention, a standard curve is stored representing the relationship between the vehicle deceleration and the pedal travel, said standard curve having a pedal travel value sP0 for a vehicle deceleration aFZG0=0 m/s.sup.2. During a brake application, pairs of values for pedal travel and vehicle deceleration are determined several times, with a pedal travel value sPi0 being determined for a vehicle deceleration of 0 M/s.sup.2 corresponding to each value pair, based on a curve that is the same as the standard curve.Type: GrantFiled: October 30, 1996Date of Patent: November 17, 1998Assignee: Mercedes-Benz AGInventors: Franz Brugger, Bernd Knoff, Wolfgang Kiesewetter, Albrecht Eckl, Manfred Steiner

Patent number: 5564797Abstract: A method is provided for determining the start and the end of an automatic braking process to optimize the triggering of the automatic braking process. When a set value is exceeded, an automatic braking process is triggered. The threshold value is changed as a function of the driving state, in particular, as a function of the speed of the vehicle when the brake pedal is actuated, and independently thereof, as a function of the position of the brake pedal. In addition, various criteria terminate the automatic braking process as a function of the actuation force of the brake pedal, of the speed of the vehicle and of the pedal travel.Type: GrantFiled: August 3, 1994Date of Patent: October 15, 1996Assignee: Mercedes-Benz AGInventors: Manfred Steiner, Wolfgang Kiesewetter, Werner Reichelt, Christoph Steffi, Joachim Nell, Siegfried Rump, Brian Douglas
