  • Patent number: 11926306
    Abstract: An electronically slip-controllable power braking system for a motor vehicle, in which a controllably drivable pressure generator supplies multiple brake circuits connected in parallel to one another with pressure medium under brake pressure. Each of the brake circuits are separable through existing first control valves from the pressure generator and include second control valves that are connected downstream from the first control valves to control the brake pressure in the wheel brakes, which are connected with the brake circuits. An electronic control unit in the brake circuits has three devices, the third device puts the first control valve of a brake circuit into a passage position if a leakage is established downstream from the second control valve in this brake circuit and if it is established that the pressure generated by the pressure generator has at least approximately reached or exceeded a pressure limit of the first control valve.

  • Patent number: 11400907
    Abstract: To avoid an exceedance of a permissible maximum pressure in a hydraulic vehicle power braking system including anti-slip regulation, continuous valves are to be utilized as inlet valves of wheel brakes of the vehicle braking system, and the inlet valve of a wheel brake, whose outlet valve will be opened or is open in order to regulate the wheel brake pressure, is to be partially closed, so that this inlet valve acts as a throttle and limits a brake pressure in the vehicle braking system.

  • Publication number: 20220028266
    Abstract: In a method for operating a vehicle which has a communication interface, a position-determining unit and at least one road data set-determining unit, a database road data set is received by the communication interface, which data set is presumably made available by the database which is arranged externally with respect to the vehicle and which is representative of the position-dependent, road-related property. Depending on the database road data set and a vehicle road data set which is assigned thereto in terms of position, a trust characteristic value is determined which is representative of the level of trust in further database road datasets which relate to predefinable positions of the vehicle.

  • Publication number: 20210000428
    Abstract: A system includes a sensor attached to an individual and detects an individual's improper body movements that increase injury risk. The system includes a safety tag with an accelerometer that measures proper acceleration. Proper acceleration along multiple directions are projected onto multiple 2-D planes, generating acceleration vectors. Phasor angles of the acceleration vectors are calculated, and if the spread in phasor angles for any one 2-D plane within a moving time window exceeds a threshold, the system determines that the individual has made an improper body movement.

  • Patent number: 9586566
    Abstract: In a method for actuating a hydraulic braking system, a hydraulic fluid is temporarily stored in a storage chamber when the antilocking system is activated and recirculated back into the brake circuit with the aid of a recirculation pump. The target pump speed of the recirculation pump depends on the degree of filling of the storage chamber with hydraulic fluid and in addition on the control frequency of the antilocking system.
