  • Publication number: 20210237699
    Abstract: The present disclosure relates to a system and a method for alternating braking for smooth stopping. The system includes a vehicle having a plurality of proximity sensors coupled to an adaptive cruise control system. A braking system is coupled to the adaptive cruise control system that controls a front and a rear wheel braking system in different patterns. When one of the proximity signals is a distance below the threshold distance, the adaptive cruise control system activates the braking system. The front and the rear wheel braking systems may be activated for a first and a second time period, respectively. The first and the second time periods correspond to a first and a second braking pattern, respectively.

  • Publication number: 20210031738
    Abstract: A method for controlling an activation state of a braking-torque assistance system for reducing intake of braking energy in a service-brake system of a vehicle includes capturing and evaluating a plurality of demand indications for a startup of the braking-torque assistance system. If the evaluation of the captured plurality of demand indications reveals a demand for the startup of the braking-torque assistance system, a plurality of operating conditions of the service-brake system are captures and evaluated over a monitoring period. If, in turn, the evaluation of the captured plurality of operating conditions reveals that an overheating of the service-brake system is imminent, the braking-torque assistance system is actuated and one or more deactivation conditions of the braking-torque assistance system are checked. If the deactivation conditions are satisfied, the braking-torque assistance system is deactivated.

  • Publication number: 20200055499
    Abstract: A method for the automated control of the longitudinal movement of a motor vehicle having an automated positive acceleration process in a longitudinal direction of the vehicle and an automated deceleration in the longitudinal direction of the vehicle. An acceleration variable is determined based on a jerk value and limited in terms of absolute value. And the jerk value is in turn determined in a driving mode in which, starting from a vehicle actual longitudinal speed and a vehicle actual longitudinal acceleration, the motor vehicle is adjusted to a predeterminable vehicle longitudinal speed taking into account a predeterminable maximum positive driving mode vehicle longitudinal acceleration, a predeterminable maximum driving mode vehicle longitudinal deceleration and at least one predeterminable driving operating mode jerk absolute value which limits the jerk.

  • Patent number: 10315630
    Abstract: A method for operating a braking assistance system of a vehicle, wherein the braking assistance system assists a braking of the vehicle by a vehicle braking device in the event of a hazard braking. To differentiate between the hazard braking and a normal braking, at least two variables, representing a braking demand of a driver of the vehicle, are ascertained and a threshold value is established for each variable wherein hazard braking is recognized when at least the two variables exceed their particular threshold value, whereupon an automated braking intervention by the braking assistance system is initiated with the aid of the vehicle braking device. Furthermore, at least one driving-situation variable representing the instantaneous driving situation of the vehicle is ascertained and the at least two threshold values are changed depending on the at least one driving-situation variable.

  • Patent number: 10259439
    Abstract: A method for controlling an electric parking brake for a motor vehicle including a brake actuator having an electric motor disposed directly on the brake caliper. When the parking brake is utilized as an additional service brake, depending on a brake pedal brake command, the electric motor is initially energized on detection of an imminent or commencing brake-pedal actuation however the electric motor generates no braking force until a predetermined or specific brake command is received. As a result, an overload of the vehicle voltage source is avoided if simultaneous utilization of multiple parking-brake actuators occurs.

  • Patent number: 10239510
    Abstract: A method of controlling a brake system of a motor vehicle having a braking assistance function. The brake system including a master brake cylinder, activated with a brake pedal. A distance s between a valve piston connected to the brake pedal, and a transmission element, connected to a pressure piston of the master brake cylinder is sensed and the brake system is controlled as a function of the sensed distance s. Within the scope of this monitoring process, brake pedal release is detected even when the pressure-generating unit is activated. In addition, despite an active braking assistance function, consistent interplay occurs between activation by the driver and assistance-side activation of the brakes given satisfactory pedal feedback.

  • Patent number: 10196062
    Abstract: A method for stopping of a motor vehicle including providing a creep torque via a drive train of the motor vehicle and then increasing, independently of the driver, engine speed of a drive engine of the drive train to increase a drive torque of the drive engine and simultaneously increasing, independently of the driver, a braking torque of a brake system of the motor vehicle to balance the drive torque and the braking torque of the motor wherein the maximum braking torque is as great as the creep torque during a standstill of the motor vehicle. The method then maintains the braking torque and simultaneously reduces the engine speed of the drive engine to point at which the motor vehicle comes to a standstill.

  • Patent number: 10160430
    Abstract: A method for operating a service brake system in a vehicle is described. The method includes the stages of determining whether the vehicle is stationary, and detecting whether the brake pressure exceeds a predetermined value in that stationary state. If the brake pressure value exceeds the predetermined value, as part of final stage, the method includes regulating the brake pressure to a predefined limiting value, where the predefined limiting value is sufficient to maintain the vehicle in that stationary state.

  • Patent number: 10124775
    Abstract: The disclosure relates to a method for operating a motor vehicle which is capable of driving either under the control of a human driver who is located on board the motor vehicle or autonomously, at least over certain sections of a route, and which is able to avoid collisions, detect adverse effects on the driver and bring about emergency stops. Accordingly, the motor vehicle has an emergency braking assistant, and if an adverse effect on the driver is detected in the autonomous driving mode, a characteristic curve which is preset for emergency braking operations is changed in such a way that an emergency braking operation is initiated at an earlier point and the braking force is built up more slowly than in the non-autonomous driving mode.

  • Patent number: 9944265
    Abstract: A method for controlling a brake pressure booster with hydraulic brake boosting wherein the activation of an additional pressure source takes place upon exceeding a specified brake cylinder pressure threshold value. The threshold value lying between 50% and 100%, preferably between 70% and 80%, of a pressure limit value, from which the operating travel/brake pressure curve without additional brake pressure assistance has a knee point. Further upon exceeding a specified piston rod activation travel limit value, which lies at 20% to 100% of the available travel, preferably at 40% to 60% of the available travel. Furthermore, the speed of the vehicle, its lateral deceleration and its longitudinal deceleration can be used as criteria. Deactivation takes place on falling below a specified piston rod deactivation travel limit value. Based on selection of activation/deactivation criteria additional brake pressure boosting can be operational during braking maneuvers.
