Patent number: 10046761Abstract: To determine an activation criterion for outputting brake signals to a vehicle brake system at least one object in the environment of the vehicle is detected. A determination is made whether the vehicle is on a collision course with the object. If so, at least one avoidance criterion is determined, wherein an S-shaped avoidance trajectory of the vehicle is determined, from which at least one extreme value of a lateral acceleration of the vehicle is determined. The extreme value is compared with at least one threshold value. The avoidance criterion is met if the associated extreme value falls below the threshold value, and the activation criterion for the brake application is not met as long as the avoidance criterion is met.Type: GrantFiled: November 30, 2013Date of Patent: August 14, 2018Assignee: WABCO GmbHInventors: Rudiger Meyer, Dirk Sandkuhler, Christian Sulzbacher

Patent number: 9566959Abstract: To determine whether an emergency braking situation exists for a vehicle, the vehicle determines at least the following state variables: its own velocity, its own longitudinal acceleration, its relative distance from an object in front, and the speed and acceleration of the object in front. A suitable evaluation method to assess whether an emergency braking situation is present is determined as a function of these state variables from a plurality of evaluation method options, including at least a movement equation evaluation method in which a movement equation system of the vehicle and of the object in front is determined, and an evaluation method in which a braking distance of the vehicle is determined.Type: GrantFiled: February 1, 2013Date of Patent: February 14, 2017Assignee: WABCO GMBHInventors: Karsten Breuer, Dirk Sandkuhler

Patent number: 9555781Abstract: To determine a triggering criterion for outputting brake signals in a vehicle, at least one object in the vehicle surroundings is sensed, and a determination is made as to whether the vehicle is on a collision course with the object. When a collision course is determined, an avoidance criterion, which is satisfied if an avoidance maneuver is not available, is checked. When the avoidance criterion is met, a braking criterion is checked. The object is classified into at least a first or a second class as a function of its properties, and the avoidance maneuver is determined as a function of such classification such that, in the case of a first class, a first avoidance trajectory is determined, and, in the case of a second class, a second trajectory, different from the first, is determined. The triggering criterion for brake signal output is satisfied when the avoidance and braking criteria are satisfied.Type: GrantFiled: November 30, 2013Date of Patent: January 31, 2017Assignee: WABCO GMBHInventors: Karsten Breuer, Rudiger Meyer, Dirk Sandkuhler, Christian Sulzbacher

Patent number: 7259661Abstract: A collision warning system and method for a motor vehicle. A measuring device in the vehicle is provided for measuring the distance dx to a second vehicle traveling ahead, the distance signal being delivered to an evaluation device in the first vehicle. The evaluation device continuously calculates a deceleration asubject vehicle demand, which is applied by the vehicle after expiration of a driver reaction time Treaction in order that a remaining distance dxremaining to the second vehicle traveling ahead can be maintained. If asubject vehicle demand exceeds an instantaneous deceleration that can be achieved by an adaptive cruise control (“ACC”) system, a system limit warning is transmitted, prompting the vehicle driver to brake with additional appropriate force. If asubject vehicle demand exceeds an assumed vehicle deceleration that can be generated by braking on the part of the driver, a collision warning signal is transmitted independently of the ACC system.Type: GrantFiled: January 24, 2005Date of Patent: August 21, 2007Assignee: WABCO GmbH & Co.
