A hydraulic actuator for supplying a hydraulic brake pressure to service brakes of a vehicle includes an actuator cylinder including a piston. A hydraulic working pressure of a brake fluid can be set in accordance with a position of the piston. The brake fluid is supplied from a hydraulic reservoir assigned to the hydraulic cylinder, and the hydraulic working pressure prevails in a working space of the actuator cylinder and can be output via an actuator output port on the actuator cylinder in order to supply a hydraulic brake pressure in accordance with the hydraulic working pressure. The hydraulic actuator further includes an electrically controllable motor. A rotary motion brought about by the electrically controllable motor can be converted by a conversion mechanism into a translational motion of the piston parallel to a longitudinal direction thus enabling a hydraulic brake pressure to be supplied by electric control of the motor.

The disclosure provides a trailer brake system that includes a sensor system and a brake control unit. The sensor system is supported by a trailer and includes at least one wheel speed sensor associated with each wheel of the trailer. The brake control unit is supported by the trailer and is in communication with a tow vehicle configured to tow the trailer. The brake control unit is configured to: receive sensor data from the sensor system, and receive a brake signal from the tow vehicle indicative of a driver pressing a brake pedal of the tow vehicle. The brake control unit is also configured to: determine, for each brake, a hydraulic pressure based on the sensor data and the brake signal; and apply pressure by way of brake lines to the brake associated with each wheel, based on the hydraulic pressure.

The present disclosure relates to a resource allocation procedure for allocating time-frequency radio resources by a scheduler in a mobile communication system. A plurality of numerology schemes are defined, each partitioning a plurality of radio resources of the mobile communication system into resource scheduling units in a different manner. A reference resource set is defined per numerology scheme, each being associated to a set of radio resources usable for being allocated according to the respective numerology scheme. The reference resource set of at least one numerology scheme overlaps with the reference resource set of at least another numerology scheme in the frequency and/or time domain. The resource allocation procedure is performed for allocating radio resources to one or more user terminals according to the numerology schemes. The resource allocation procedure is performed for each numerology scheme based on a scheduling time interval defined for the respective numerology scheme.
