Patent number: 9796366Abstract: A braking device for a motor vehicle has a setpoint controlled deceleration device, which, upon receipt of a braking request input by a driver or an assistance system, for example, on the basis of a difference between a setpoint value and an actual value, drives a brake of the vehicle to generate a setpoint controlled braking torque for a deceleration of the motor vehicle. In addition, the braking device has a braking preparation control, which, upon receipt of a braking preparation signal, drives the brake independently of the setpoint value to produce at least one braking pressure for generating a preparation braking torque for a pre-deceleration of the motor vehicle. The braking preparation signal is generated as soon as a driving situation is ascertained where a braking request input by a driver or an assistance system is very likely imminent.Type: GrantFiled: September 10, 2013Date of Patent: October 24, 2017Assignee: ROBERT BOSCH GMBHInventors: Christian Korthals, Michael Bachmann, Harald Michi, Michael Schubert

Patent number: 6853906Abstract: A method and a device are described for determining a future travel-path area of a first vehicle, which is furnished with a distance sensor. In this context, using the distance sensor at pre-established or selectable time points, at least relative positions are determined of at least one vehicle traveling ahead with respect to the first vehicle. At least these determined relative positions are stored in at least one storage device. These relative positions, stored in the storage device, constitute in each case a course path of the corresponding vehicle traveling ahead. The future travel path area of the first vehicle is determined at least on the basis of the course path of the vehicle traveling ahead. The course path of the vehicle traveling ahead is projected in the direction of the position of the first vehicle.Type: GrantFiled: October 6, 1999Date of Patent: February 8, 2005Assignee: Robert Bosch GmbHInventors: Harald Michi, Michael Scherl, Bernd Lichtenberg, Werner Uhler
