Publication number: 20140257665Abstract: A method for cruise and/or range control of motor vehicles with range-controlled cruise control systems, wherein, during a determination of a desired acceleration value, for reaching a predefined speed and/or a predefined distance to a target object traveling ahead during a following travel, specific data of a target object traveling ahead and of a front object traveling in front of the target object are taken into account. As a function of the specific data of the target object driving ahead, a first desired pre-acceleration value is determined and, as a function of the specific data of the front object driving ahead, a second desired pre-acceleration value is determined. From the first desired pre-acceleration value and the second desired pre-acceleration value, by weighting the two desired pre-acceleration values, the relevant desired acceleration value is determined.Type: ApplicationFiled: June 4, 2013Publication date: September 11, 2014Inventors: Walter KAGERER, Maria-Christina LAIOU

Patent number: 8788175Abstract: A method of controlling the speed and/or the distance for motor vehicles having distance-controlled cruise control systems is provided in which a sensor unit determines relevant data of a vehicle driving ahead. In the event of a detection of a target object driving ahead, desired acceleration values and/or desired deceleration values for reaching a predetermined desired distance to the target object are determined and outputted. While considering the relevant data of the target object, a swinging-out probability of the target object is determined and, as a function of the determined swinging-out probability, an adaptation of the desired distance to the target object is carried out.Type: GrantFiled: February 12, 2013Date of Patent: July 22, 2014Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Walter Kagerer, Maria-Christina Laiou, Torsten Seyffarth

Patent number: 8036804Abstract: The invention relates to a method for controlling speed and/or distance in motor vehicles having distance-related longitudinal control systems, wherein during clear driving, a clear drive acceleration value is set to reach a preset speed, and while following a detected target object, a following acceleration value is set to maintain a preset distance from the target object, and wherein if the target object is lost during a following drive operation, a transition acceleration value is set. According to the invention, the transition acceleration value is set for the duration of a time interval, which is dependent on the speed at the time of the target object loss.Type: GrantFiled: March 17, 2011Date of Patent: October 11, 2011Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Maria-Christina Laiou, Alexander Meske, Falk Langer

Patent number: 8027774Abstract: A method ensures the standstill of a motor vehicle. Before reaching the standstill, an electronic control unit checks whether a predefined inclination threshold is exceeded, whether the velocity has fallen below a predefined travel velocity threshold, and whether there is a negative vehicle acceleration. If all three conditions exist simultaneously, an increased setpoint braking torque is predefined until the motor vehicle reaches the standstill.Type: GrantFiled: November 27, 2007Date of Patent: September 27, 2011Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Maria-Christina Laiou, Falk Langer

Patent number: 7970525Abstract: The invention relates to a method for determining the vehicle speed of a motor vehicle, wherein a provisional first speed value is determined for high speeds and a provisional second speed value is determined for low speeds and the vehicle speed is determined as a function of the determined provisional first speed value either from the provisional first speed value or from the provisional second speed value, or from a combination of the first and second speed values.Type: GrantFiled: May 21, 2009Date of Patent: June 28, 2011Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Maria-Christina Laiou, Alexander Meske, Walter Kagerer, Falk Langer

Patent number: 7627415Abstract: In a device for securing the standstill of a motor vehicle with a distance-related longitudinal dynamic control module, which is contained in at least one electronic control unit and by which the motor vehicle is decelerated down to a standstill while maintaining a defined distance from a target object, at least until reaching the standstill, a nominal brake torque is defined by the longitudinal dynamic control module for a brake control module. At a defined first time after a detected standstill of the motor vehicle, the longitudinal dynamic control module transmits a transfer signal to the brake control module. Thereupon, independently of the predefinition of a nominal brake torque by the longitudinal dynamic control module, the brake control module alone builds up and/or holds a wheel brake torque in the sense of a parking brake function.Type: GrantFiled: February 1, 2008Date of Patent: December 1, 2009Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Oliver Tschernoster, Carsten Hass, Sonja de Castro Bonfim, Leander Kempenaars, Christian Scheinost, Bartono Adiprasito, Maria-Christina Laiou, Andreas Pfeiffer
