Publication number: 20230398966Abstract: A yaw rate control method comprises a yaw rate control function for stabilizing a vehicle carries out wheel-specific braking interventions based on a first reference yaw rate. A deactivation function is provided and activates the yaw rate control function as soon as at least one activation requirement is met. The activation requirement checks whether a longitudinal deceleration is greater than a longitudinal deceleration limit value, in particular by a sensor tolerance, a lateral acceleration is greater than a lateral acceleration limit value, in particular by a sensor tolerance, and a deviation between a second reference yaw rate and a measured yaw rate is greater than a yaw rate deviation limit value, in particular by a sensor tolerance.Type: ApplicationFiled: October 6, 2021Publication date: December 14, 2023Applicant: Continental Automotive Technologies GmbHInventors: Henning Kerber-Wunderlich, Lennart Schmidt

Patent number: 11167738Abstract: The invention relates to a method for improving the control behavior of an electronic motor vehicle braking system which comprises at least a slip control function. Wheel dynamic information which is evaluated as a criterion for initiating a control intervention is used individually for each wheel and is compared with control thresholds for a pressure reduction phase, a pressure maintenance phase, and a pressure buildup phase for generating corresponding braking torques by means of a vehicle braking system.Type: GrantFiled: April 10, 2015Date of Patent: November 9, 2021Assignee: Continental Teves AG & Co.

Patent number: 10328914Abstract: A method for setting a slip threshold for a vehicle movement dynamics control device of a motor vehicle is provided. The method includes defining a slip threshold starting from which the vehicle movement dynamics control device is activated in order to reduce slip, and determining wheel-specific minimum slip values for the wheels of the motor vehicle, which slip values are derived from the respective wheel-specific slip signals. The method also includes detecting a geometric slip by correlating all the determined wheel-specific minimum slip values with one another, and evaluating the wheel-specific minimum slip values that are correlated with one another. The method also includes raising the slip threshold in the event of geometric slip being detected. The present disclosure also relates to a vehicle movement dynamics control device.Type: GrantFiled: November 17, 2016Date of Patent: June 25, 2019Assignee: Continental Teves AG & Co. oHGInventors: Henning Kerber, Manuel Kasten, Mario Roszyk, Dieter Burkhard

Patent number: 10315634Abstract: The disclosure relates to a method for adapting a control strategy of a slip-control system of a brake system of a vehicle in a ?-split situation, in which different wheel-specific brake pressures, are set at opposite wheels of a vehicle axle. The resulting brake pressure difference is limited. In some examples, to generate a brake pressure request, a maximum pressure difference value deviating from a reference pressure difference with a predefined tolerance value is determined on a wheel-specific basis for the wheels lying opposite one another. The reference pressure difference corresponds to the value of the current low-pass-filtered brake pressure difference, and the brake pressure request for each wheel is determined as a minimum of the wheel-specific brake pressure determined from the control strategy of the slip-control system, and from the sum of the average brake pressure of the wheel lying opposite and the wheel-specific maximum pressure difference value.Type: GrantFiled: February 15, 2017Date of Patent: June 11, 2019Assignee: Continental Teves AG & Co. oHGInventors: Henning Kerber, Mario Roszyk, Jochen Müller, Arne Cornils, Dieter Burkhard

Patent number: 10293797Abstract: A method for avoiding false excitations of a slip control system comprises monitoring of a wheel speed signal for a predefined first monitoring time period for the start of a negative half-wave of an oscillation applied to a vehicle wheel, when a brake pressure gradient initiated by a brake start rises above a predetermined threshold. A ruck signal is derived from the wheel speed signal. An acceration signal is derived from the wheel speed signal during a predetermined second monitoring period. The wheel speed signal is monitored for a turning point of the ruck signal and a start of the acceleration signal. The oscillation imposed on the vehicle wheel is identified as a braking-induced vibration, and slip control is not carried out when the turning point of the ruck signal and the re-acceleration of the wheel are detected.Type: GrantFiled: December 15, 2016Date of Patent: May 21, 2019Assignee: Continental Teves AG & Co. oHGInventors: Manuel Kasten, Henning Kerber, Jochen Müller, Mario Roszyk

Patent number: 9694795Abstract: A method for determining the conditions of an underlying surface during unbraked or braked travel of a vehicle by a wheel-specific characteristic variable which is derived from a change over time in the wheel speed detected at at least one vehicle wheel. According to invention there is provision that a) a jolt signal is formed by double differentiation of the wheel speed, b) in order to form the characteristic variable the difference between the absolute value of the jolt signal and a tolerance value is summed or integrated over time, and c) the condition of the underlying surface is determined by comparing the characteristic variable with an oscillation signal threshold value.Type: GrantFiled: April 14, 2014Date of Patent: July 4, 2017Assignee: Continental Teves AG & Co. oHGInventors: Henning Kerber, Mario Roszyk, Dieter Burkhard

Patent number: 8308248Abstract: A method for operating a vehicle brake system and a corresponding vehicle brake system, particularly for motor vehicles. The vehicle wheels of the motor vehicle associated with an axle are at least partially driven by ‘WV’ an electric motor that can be operated as a generator during regeneration of braking energy, thus exerting a braking regeneration el torque on the respective axle. To prevent overbraking on the rear axle, the regeneration torque acting on at least one rear axle (HA) is limited such that the slippage present on the at least one vehicle wheel of the rear axle (HA) does not exceed or only negligibly exceeds a first slippage threshold individually associated with the respective vehicle wheel.Type: GrantFiled: April 3, 2008Date of Patent: November 13, 2012Assignee: Continental Teves AG & Co. oHGInventors: Markus Jäger, Henning Kerber, Roger-Lutz Müller
