Patent number: 9227606Abstract: A method for operating a braking system of a vehicle having at least one brake-able wheel, a braking force variable, which represents a braking force, of a braking device associated with the wheel being increased during a braking operation until a locking tendency of the wheel is recognized, and then reduced to a certain value. It is provided that the braking force variable is subsequently set to a setpoint braking force variable, which corresponds to a selectable portion of the braking force variable present at the recognition of the locking tendency, for a certain time period. Also described is a control unit for implementing the method.Type: GrantFiled: November 12, 2010Date of Patent: January 5, 2016Assignee: ROBERT BOSCH GMBHInventors: Alfred Strehle, Stefan Diehle, Achim Eisele

Patent number: 6658343Abstract: A method of stabilizing a vehicle equipped with a slip-controlled brake system is described. This is done by determining the wheel speeds of the individual wheels of the vehicle. For at least one wheel, a wheel speed setpoint is determined. For the at least one wheel, a deviation quantity describing the deviation between the wheel speed determined for that wheel and the setpoint is determined. To stabilize the vehicle, actuators assigned to the at least one wheel are activated as a function of this deviation quantity.Type: GrantFiled: August 20, 2001Date of Patent: December 2, 2003Assignee: Robert Bosch GmbHInventors: Matthaeus Koch, Steffen Ullmann, Ruediger Poggenburg, Oliver Lah, Stefan Diehle

Patent number: 6623090Abstract: A panic braking operation of a vehicle having at least two wheels is detected by measuring speed quantities which represent the rotary motions of at least two wheels, selecting the speed quantity of one of the wheels and/or by determining a speed value from the speed quantities, determining a change value which represents the time-related change of the selected speed quantity and/or of the speed value, determining the time characteristic of the change value, and detecting a panic braking operation as a function of the time characteristic of the change value. What is advantageous here is that no complex and expensive additional sensor technology is needed for detecting panic braking; the wheel-speed sensors which are provided anyway in anti-lock control systems, traction control systems, and/or vehicle stability control systems are sufficient. Thus, the use of a panic detection is also possible in so-called “low-cost braking systems”.Type: GrantFiled: July 2, 2001Date of Patent: September 23, 2003Assignee: Robert Bosch GmbHInventors: Steffen Ullmann, Ruediger Poggenburg, Thomas Opferkuch, Stefan Diehle

Patent number: 6523914Abstract: A method or apparatus for controlling a braking system in a vehicle, the vehicle including an inside front wheel and outside front wheel, whereby a determination is made of whether a drifting and/or an oversteering condition exists; and, if so, a predetermined braking pressure is applied to the outside front wheel.Type: GrantFiled: March 14, 2001Date of Patent: February 25, 2003Assignee: Robert Bosch GmbHInventors: Ruediger Poggenburg, Stefan Diehle, Werner Langer

Patent number: 6510373Abstract: A lane change by a motor vehicle is detected in a first variant, such that a lateral-acceleration variable representing the lateral acceleration of the vehicle and/or a yaw variable representing the yaw velocity is ascertained; the change, as a function of time, of the lateral-acceleration variable and/or of the yaw variable is formed; and a lane change is detected when the change as a function of time exceeds a specifiable threshold value. A second variant provides that speed variables are determined which represent the rotations of at least two wheels; a velocity variable is ascertained representing the longitudinal vehicle velocity; the difference is determined between the speed variable of the fastest rear wheel and the velocity variable; and a curve and/or a lane change is detected when a specifiably large difference exists for a time duration of specifiable length.Type: GrantFiled: June 27, 2001Date of Patent: January 21, 2003Assignee: Robert Bosch GmbHInventors: Bernd Grossardt, Uwe Pruhs, Stefan Diehle, Werner Langer

Patent number: 6445994Abstract: A method and device for detecting cornering of a vehicle, or for ascertaining the transverse acceleration (ay) of a vehicle, where a signal indicating cornering of the vehicle, a measure of the curve radius, or the transverse acceleration (ay) of the vehicle is detected, using a reference speed (vS, vSL, vSR) for at least each side of the vehicle; and where a reference speed (vS, vSL, vSR) of one side of the vehicle is determined as a function of the deceleration of at least one wheel on this side of the vehicle.Type: GrantFiled: December 22, 2000Date of Patent: September 3, 2002Assignee: Robert Bosch GmbHInventors: Ruediger Poggenburg, Uwe Pruhs, Stefan Diehle

Patent number: 6375280Abstract: A method and a device for adjusting a braking action at wheels of a motor vehicle are described. In response to a detected &mgr;-split situation, a reduction of the braking action at a low wheel of a rear axle is brought about as a function of a reduction of the braking action at a same-side wheel of a front axle. One variant of the method and device no braking action is applied to the low wheel of the rear axle. As a result of the two variants, the low wheel of the rear axle, which is at a side that has a lower coefficient of friction and does not significantly contribute to the overall braking action, is rendered virtually without brake pressure and can therefore function as a reference variable, i.e., vehicle reference velocity. As a result, especially in light commercial vehicles, the braking distances are shorter in response to braking actions in a &mgr;-split while maintaining stable driving performance during the entire braking action.Type: GrantFiled: November 16, 2000Date of Patent: April 23, 2002Assignee: Robert Bosch GmbHInventors: Ruediger Poggenburg, Stefan Diehle

Patent number: 6102492Abstract: The invention relates to a method and device for controlling braking force distribution in a motor vehicle. In the case of failure of the braking system, the braking force distribution regulator enters emergency mode. The regulation is activated when the speed and the deceleration of the vehicle exceed given minimum values. The invention also concerns emergency measures for regulating the braking force distribution in the case of the certain individual errors.Type: GrantFiled: October 5, 1998Date of Patent: August 15, 2000Assignee: Robert Bosch GmbHInventors: Stefan Diehle, Alfred Strehle

Patent number: 6019442Abstract: In a method of controlling a braking system in a vehicle, the action of the brakes is distributed between at least one front and one rear wheel by adjusting at least the braking pressure in the brakes on one of the rear wheels in order to establish a difference between the braking pressure on the front wheel and that on the rear wheel. The difference established between the braking pressure on the front wheel and that on the rear wheel is decreased in the presence of a prescribable condition. The presence of the prescribable condition depends at least on a detected parameter that represents the longitudinal velocity of the vehicle, and the established difference is continuously decreased.Type: GrantFiled: December 11, 1997Date of Patent: February 1, 2000Assignee: Robert Bosch GmbHInventors: Juergen Zechmann, Stefan Diehle
