Abstract: A method for sending messages from a vehicle to a receiver during travel by the vehicle is disclosed. The method includes (i) estimating a first future trajectory of the vehicle, (ii) sending trajectory information about the first trajectory to the receiver, (iii) determining a deviation of an actual position of the vehicle from a position predicted by the first trajectory, (iv) estimating a second future trajectory, and (v) sending trajectory information about the second trajectory to the receiver if the deviation is greater than a threshold value.

Abstract: A method for the communication of at least two users of a networked traffic system. A first user sends pieces of exchange information using a first signal transmission path, the pieces of exchange information including first sensor data of the first user and a code representing the first user. The first user sends the representative code or one further representative code using at least one second signal transmission path. A second user receives the pieces of exchange information via the first signal transmission path. The second user ascertains using a surroundings sensor system second sensor data by detecting surroundings. The second user receives using the surroundings sensor system the code sent via the second signal transmission path. The second user associates the first sensor data and the second sensor data with one another with the aid of the representative code and/or with the aid of the further representative code.

Abstract: A method for controlling the operation of a hydraulic braking system of a vehicle and in particular a vehicle drivable using muscle power and/or—in particular additionally—using motor power, an electric bicycle, e-bike, pedelec, or the like. In the method, it is checked whether a discharge condition for discharging an accumulator of the braking system is met. If the discharge condition is met, initially a controllable inlet valve in a primary circuit of the braking system is set into a partially closed state over a predefined duty cycle, in particular of 10%, and/or for a predefined time span and then an outlet valve of the accumulator is opened for a predefined time span—continuously or in intervals—so that brake fluid is discharged from the accumulator via the outlet valve, the primary circuit, and the inlet valve into a reservoir of a master cylinder of the primary circuit.

Abstract: A control method includes at least one emission of a radar signal into an area that encompasses a base surface of the roadway section and a wheel of a vehicle, for example an electric bicycle. A radar frequency spectrum reflected on the base surface and on the wheel is subsequently detected using the radar sensor. A control unit actuates at least one brake, for example a front wheel brake of the electric bicycle, as a function of a difference between the vehicle speed and the wheel speed recognized based on the detected radar frequency spectrum.

Abstract: A circuit for a micromechanical structure-borne sound sensor and a method for operating this sensor, a voltage generator being used to apply voltages to at least one micromechanical element for recording the structure-borne sound, so that a change in the micromechanical element occurs. In addition, an evaluation circuit is provided, which records the at least one electrically recordable parameter of micromechanical element at a sampling rate and analyzes the same. This at least one parameter changes in response to the change. A clock-pulse generator is also provided for generating the sampling rate and for generating the clock pulse. A frequency generator is used for generating the clock pulse at least intermittently for the test operation, the frequency generator producing the clock pulse as a multiple or as a submultiple of the sampling rate.
