METHOD FOR ADJUSTING THE APPLIED PRESSURE OF A VEHICLE BRAKE AND VEHICLE BRAKE IN QUESTION
A method is for adjusting an application pressure of a vehicle brake, in particular a commercial vehicle disc brake, of a motor vehicle while the motor vehicle is in motion. The method includes the following steps: applying an initial application pressure to the vehicle brake, determining a braking effect of the vehicle brake while the initial application pressure is applied to the vehicle brake, comparing the determined braking effect with a limit braking effect, reducing the initial application pressure to a reduced application pressure if the determined braking effect exceeds the limit braking effect.
Electromechanical brake system
A brake system includes an electromechanical brake having a friction surface, a lining support having a brake lining, an electric motor for moving the lining support, and a control and monitoring unit. The control and monitoring unit ascertains, from a first value ascertained during a first movement of the lining support by the electric motor, an operating parameter of at least one part of the brake, and a second value ascertained during a second movement opposite to the first movement of the lining support, by the electric motor, an operating behavior value for a real operating behavior of the relevant brake, and ascertains, by comparing the at least one real operating behavior value to at least one stored operating behavior expectation, a correction factor. The brake control system is corrected by the one correction factor and a regulator of the electric motor is activated using the corrected brake control signal.
Risk reduction in road traffic
In a method for reducing risks in road traffic, using a motor vehicle an information signal is generated and transmitted to an analysis unit. The information signal contains a position of the corresponding motor vehicle and an associated hazard level. Using the analysis unit, the position is assigned to a route section and a risk characteristic value is determined as a function of the hazard level. Using the analysis unit, a risk signal is generated based on the risk characteristic value and provided to at least one traffic participant.
Brake preload system for autonomous vehicles
Vehicles according to at least some embodiments of the disclosure include a sensor, and a computing device comprising at least one hardware processing unit. The computing device is programmed to perform operations comprising capturing an image with the sensor, identifying an object in the image, and in response to an accuracy of the identification meeting a first criterion, pre-loading a braking system of the autonomous vehicle. In some aspects, the computing device may predict that an object not currently within a path of the vehicle has a probability of entering the path of the vehicle that meets a second criterion. When the probability of entering the path meets the second criterion, some of the disclosed embodiments may pre-load the braking system.
METHOD, APPARATUS, AND COMPUTER-READABLE STORAGE MEDIUM FOR PERFORMING A BRAKING OPERATION OF A VEHICLE
Method, apparatus, and computer-readable medium for performing a braking operation of a vehicle when an object is detected in front of the vehicle. The method includes acquiring at least one image of an external environment of the vehicle, determining a road condition of a road of the external environment of the vehicle based on the acquired at least one image, obtaining, based on the determined road condition and from memory, a braking table of one or more braking tables including distances and corresponding vehicle speeds at which the braking operation is performed, acquiring a speed of the vehicle and a distance between a preceding object and the vehicle, comparing the acquired speed of the vehicle and the acquired distance between the preceding object and the vehicle to the braking table, and sending, based on the comparison, an instruction to perform the braking operation of the vehicle.

An electric brake including: a brake mechanism configured to transmit a thrust force generated through drive of an electric motor to a piston, the piston being configured to move brake pads to be pressed against a disc rotor; a thrust force sensor configured to detect the thrust force transmitted to the piston; and an ECU for rear electric brake configured to control, based on a detection value obtained by the thrust force sensor, the drive of the electric motor in accordance with a brake command. The ECU for rear electric brake is configured to learn, as a reference point of a piston thrust force, a detection value obtained by the thrust force sensor when the electric motor is driven to move the piston in a direction for pressing the piston against the disc rotor in a range in which the brake pads are not in contact with the disc rotor.

METHOD FOR OPERATING A BRAKE SYSTEM, AND BRAKE SYSTEM
A method for operating a brake system of a vehicle. A precontrol value for a brake pressure of the brake system is set by using an admission pressure value representing a admission pressure in the brake system and a processing specification representing a braking dynamics of the vehicle.
METHOD FOR CONTROLLING THE BRAKING POWER IN AN ELECTROHYDRAULIC BRAKING SYSTEM OF A MOTOR VEHICLE
A method for controlling the braking power in an electrohydraulic braking system of a transportation vehicle which includes initiating a braking process; detecting a current state of the electrohydraulic braking system; increasing the braking pressure based on the current state of the electrohydraulic braking system, wherein braking pressure is built up more rapidly by targeted, staggered supply of braking pressure to individual parts of the braking system.
Cruise control cancel, with brake precharge
A hydraulic brake system for a vehicle which has expanded functionality, where a pre-charge occurs in the brake system upon deactivation of the cruise control, reducing the time needed to generate pressure in each brake unit, reducing stopping distance. The pre-charge function involves generating pressure in each caliper of the brake system upon deactivation of the cruise control function of the vehicle, such that the hydraulic brake system is pre-charged prior to the driver of the vehicle applying force to the brake pedal, which reduces stopping distance. One aspect of the pre-charge function includes generating enough pressure such that the brake pads contact each corresponding rotor. Another aspect of the pre-charge function includes generating enough pressure such that the brake pads apply force to each corresponding rotor, providing a minimum amount of deceleration prior to the driver of the vehicle applying force to the brake pedal.
