  • Patent number: 12269445
    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.

  • Patent number: 12116082
    Abstract: A method for operating a two-wheeler. The two-wheeler includes a drive unit and a sensor system, the sensor system including a rotation rate sensor, an acceleration sensor, and a wheel speed sensor. The wheel speed sensor detects at least one measuring pulse per revolution of a wheel of the two-wheeler. The method includes: detecting three-dimensional rotation rates of the two-wheeler, detecting acceleration values of the two-wheeler, and estimating a motion state of the two-wheeler based on the detected rotation rates, the motion state including estimated values for estimated acceleration values and an estimated speed and an estimated distance covered, first correction of the estimated motion state based on the detected acceleration values, ascertaining an instantaneous steering angle of the two-wheeler based on the corrected estimated motion state, and actuating the drive unit and/or an antilocking system of the two-wheeler as a function of the ascertained instantaneous steering angle.

  • Publication number: 20240174319
    Abstract: A vehicle is driven by muscle power and/or an electric motor and includes a brake assistance device for a hydraulic brake system. The brake assistance device has a sensor with a first piston, a compensation volume with a second piston and a pretensioning element, a 2/2-way valve, a brake piston, and an actuator. The pretensioning element is configured to exert a pressure onto the second piston and thus onto a hydraulic fluid of the hydraulic brake system. The actuator is configured to move the second piston selectively in a first direction or in a second direction oriented opposite the first direction.

  • Patent number: 11175678
    Abstract: A method for laterally stabilizing a single-tracked motor vehicle, driven with the aid of an electric motor, that is in a vertically aligned state and at a standstill. The front wheel of the motor vehicle has a steering angle in which the electric motor is controlled in such a way that it exerts drive torques on the motor vehicle that act in alternation in the forward direction and in the reverse direction.

  • Publication number: 20200062335
    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.
