Publication number: 20220340175Abstract: An autonomous system for a vehicle, having a control device. The autonomous system, when there is a functional impairment of the autonomous system and/or of a controlled vehicle component, is in a transition mode for at least a specified minimum transition time, in which mode the controlled component and/or at least one additional vehicle component of the traveling vehicle is controllable by the control device corresponding to a specified transition program. After the elapse of the minimum transition time, the autonomous system is in its transition mode until either a specified maximum transition time has elapsed or at least one current speed of the vehicle is below a specified maximum speed, there is a request by the driver for the acceleration of the vehicle, a current transverse acceleration of the vehicle is below a specified maximum transverse acceleration, and/or at least one vehicle stabilization controller of the vehicle is inactive.Type: ApplicationFiled: August 10, 2020Publication date: October 27, 2022Inventors: Alfred Strehle, Thomas Schmidt

Patent number: 10875510Abstract: A method for controlling an electronically slip-controllable power braking system of a motor vehicle. Power braking systems are equipped with a plunger unit, which includes a plunger piston accommodated in a plunger cylinder and delimiting a working chamber, for generating brake pressure in brake circuits. This plunger piston is actuatable by an electronically activatable drive in a pressure buildup direction or in the opposing spatial direction thereto in a pressure reducing direction. A time-limited drive of the plunger piston takes place in the pressure reducing direction as soon as an actual brake pressure generated by the plunger unit has reached a predefinable setpoint brake pressure and a decoupling of a wheel brake and the plunger unit from an associated brake circuit has taken place.Type: GrantFiled: April 24, 2019Date of Patent: December 29, 2020Assignee: Robert Bosch GmbHInventors: Jens Wagner, Matthias Kranich, Nicholas Taubitz, Reid Collins, Stefan Zahariev, Alfred Strehle

Patent number: 10286884Abstract: A vehicle brake system having electronic pressure regulation and a related method, in which the system stabilizes a vehicle, supports the actuation of the brake system, and/or enables a fully/partly automated driving operation. The system has a primary actuator system that sets/regulates different brake pressures at the wheel brakes, and an electronically controllable secondary actuator system that secures the vehicle brake system against primary actuator failure. For a primary actuator error, the secondary actuator is controlled so that the secondary system produces a brake pressure that, based on the dynamic axle load displacement, occurring during a braking process, in the direction of a front axle, is greater than the brake pressure that is convertable into a rear axle wheel brake braking power. A device reduces this brake pressure at the rear axle wheel brake to a value at which the vehicle wheel, assigned to this wheel brake, does not lock.Type: GrantFiled: May 1, 2017Date of Patent: May 14, 2019Assignee: ROBERT BOSCH GMBHInventors: Alfred Strehle, Marko Flinner, Matthias Schanzenbach, Thomas Schmidt
