摘要： A vehicle includes a brake-by-wire system having a brake pedal and a first sensor configured to output a signal indicative of a position of the brake pedal. A controller is in communication with the sensor and is programmed to enable and disable a one-pedal driving mode based on a user-selected setting. The controller is further programmed to, in response to the signal of the first sensor being valid and the one-pedal driving mode being disabled, enable the one-pedal driving mode regardless of the user-selected setting.

摘要： A vehicle control system for controlling braking in a vehicle may include a braking system operably coupled to one or more wheels of the vehicle to provide brake inputs to the one or more wheels responsive to a torque request generated based on pedal position. The system may further include a pedal position sensor operably coupled to a brake pedal to determine the pedal position responsive to actuation of the brake pedal by a driver of the vehicle, a pedal feel simulator operably coupled to the brake pedal to provide tactile feedback to the driver via a pedal force applied to the brake pedal, an accelerometer for determining a rate of velocity reduction of the vehicle during the actuation of the brake pedal, and a feedback augmenter operably coupled to the pedal feel simulator to provide a pedal force offset to increase the pedal force provided to the brake pedal based on the rate of velocity reduction.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method for controlling a brake system of a motor vehicle wherein a central generation of brake-fluid pressure takes place electrically and essentially mechanically decoupled from the movement of a brake-actuating element. The brake pressure of individual wheels can be selectively modified depending on driving-dynamics parameters by activating hydraulic check-valve and drain-valve elements. In the case of braking events occurring before stability and/or slip limits are reached, which limits would make it necessary to use the antilock braking system and/or a stability program, the brake pressure is reduced such that the use of the hydraulic valve elements for the antilock brake system and/or the stability program is time-delayed. Further, blocking the supply of brake fluid to individual wheels or creating pressure-decrease states for individual wheels is minimized with respect to time.

摘要： 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.
