Abstract: An electric brake system for a vehicle is provided, wherein the vehicle has a brake value encoder, at least one first axle having at least two wheels and a second axle having at least two wheels. A first axle modulator is associated with the first axle. A second axle modulator is associated with the second axle. A single central control unit is further provided, which generates and outputs a first brake signal for the first axle modulator and a second brake signal for the second axle modulator as a function of a brake signal from the brake value encoder or as a function of a further brake request. The first and second axle modulator are each configured to decelerate the wheels of the first and second axle as a function of the first and second brake signal from the central control unit.

Abstract: The present disclosure relates to methods, systems, a vehicle and a computer-readable storage medium and a computer program product. The method includes obtaining a near-collision warning signal from a collision warning system of the vehicle, the near-collision warning signal being representative of a collision event determined based on sensor data representative of a surrounding environment of the vehicle. The method further includes obtaining an operational position of an accelerator pedal of the vehicle configured for operating the vehicle by means of a one pedal driving control system. Further, the method includes generating, based on the obtained near-collision warning signal, a corresponding negative torque reinforcement factor to be applied to a normal braking force of the vehicle associated with each obtained operational position of the accelerator pedal.

Abstract: A brake control device includes a processor that controls a brake device of a vehicle. The processor receives a first braking request indicating first braking force by the brake device which is requested from an application that implements a driver assistance function of the vehicle. The processor receives a second braking request indicating second braking force by the brake device which is requested depending on an operation amount of a brake pedal of the vehicle. The processor starts override control when the processor receives the second braking request while the processor controls the brake device in accordance with the first braking request.

Abstract: [Problem] The present invention provides a vehicle brake system capable of shortening a delay time from time at which an execution request of a pre-crash brake executed by actuation of an electric booster is sent to time at which the pre-crash brake is actually actuated.
[Means for Resolution] In a vehicle brake system (1) including: a hydraulic unit (20); a braking control section (90) for controlling the hydraulic unit (20); a master cylinder (14); an electric booster (10); a booster control section (100) for controlling the electric booster (10); and a pre-crash brake execution determination section (110), the pre-crash brake execution determination section (110) sends information on a specified target value (P_tgt) for decelerating a vehicle to the booster control section (100) and the braking control section (90). When a change amount (ΔP) of the target value (P_tgt) received from the pre-crash brake execution determination section (110) exceeds a specified threshold value (ΔP_thr), the booster control section (100) drives the electric booster (10) prior to a command from the braking control section (90) and executes preceding brake control for generating a specified brake hydraulic pressure to a wheel cylinder.

Abstract: A method for monitoring an implementation of an assistance braking specification, requested in an automated fashion by a brake system in a vehicle includes: detecting whether an assistance braking specification which is requested in an automated fashion is present; detecting an actual dynamics variable, the actual dynamics variable including wheel dynamics of at least one wheel of the vehicle and/or of a trailer, the actual dynamics variable being assigned to a wheel which is to be braked as a result of the assistance braking specification which is requested in an automated fashion; determining a reference dynamics variable, the reference dynamics variable including driving dynamics of the vehicle and/or of the trailer; and comparing the actual dynamics variable with the reference dynamics variable. When an assistance braking specification is present: a faultfree implementation of the assistance braking specification which is requested is detected if the actual dynamics variable deviates.

Abstract: A control device configured to control motion of a vehicle includes a controller. The controller is configured to execute braking control that generates a braking force for decelerating the vehicle in response to a braking request. The controller is configured to release the braking force by the braking control when a predetermined condition for continuing the braking control is not satisfied, and to maintain the braking force by the braking control when the predetermined condition is satisfied, in a case where an accelerator pedal is operated during execution of the braking control.
