System and method for automatically longitudinally guiding a motor vehicle to a standstill
A system and a method automatically longitudinally guide a motor vehicle. The system is used to automatically brake the motor vehicle to a standstill on the basis of a detected infrastructure component which requires a braking of the motor vehicle to a standstill. The system includes a sensor unit which is designed to detect an infrastructure component that requires a braking of the motor vehicle to a standstill, a first determining unit which is designed to determine a standstill position on the basis of currently provided information of the sensor unit upon detecting the infrastructure component, a second determining unit which is designed to determine an adapted standstill position upon no longer detecting the infrastructure component on the basis of the determined standstill position when the infrastructure component was still detected, and a control unit which is designed to automatically initiate a braking to the standstill into the determined standstill position or the determined adapted standstill position.

Front impact mitigation system for a vehicle and method
A front impact mitigation system for a host vehicle and a method for operating a front impact mitigation system. The front impact mitigation system can take into account the position of a rear object that trails the host vehicle to develop a modified front impact mitigation control signal that at least partially mitigates the likelihood of certain rear impact collisions between the rear object and the host vehicle when the host vehicle is responding to the presence of an impending leading obstacle. A modified front impact mitigation control signal may be developed to account for the speed of the host vehicle and the distance that the rear object trails the host vehicle.

Method for teaching switching parameters of a solenoid control valve in a braking system of a vehicle, and braking system
A method for specifying switching parameters of a solenoid control valve in a braking system of a vehicle includes stipulating a test vehicle acceleration and ascertaining at least two test pulse sequences. The test pulse sequences are each ascertained on the basis of the stipulated test vehicle acceleration and on the basis of switching parameter default values for the respective solenoid control valve, and the test pulse sequences have actuation pulses and adjoining nonactuation pulses. During an actuation pulse an activation of the respective solenoid control valve and during a nonactuation pulse a deactivation of the respective solenoid control valve takes place. The method further includes actuating the respective solenoid control valve using the at least two test pulse sequences in order to cause at least two test braking operations, wherein the respective test pulse sequence causes an alteration of a braking pressure at a service brake.

Method and subsystem for controlling an autonomous braking system for a vehicle
A control system for a subject vehicle includes an autonomous braking system, a forward monitoring sensor and a rearward monitoring sensor. The controller monitors a first speed of a first vehicle travelling in front of the subject vehicle and a second speed of a second vehicle travelling to the rear of the subject vehicle. A first gap-closing time is determined based upon the speed of the subject vehicle and the first speed of the first vehicle. A second gap-closing time is determined based upon the speed of the subject vehicle and the second speed of the second vehicle. The controller controls the speed of the subject vehicle based upon the first gap-closing time and the second gap-closing time when one of the first gap-closing time or the second gap-closing time is less than a first threshold time.
