Abstract: A slip-controllable vehicle brake system includes a drivable pressure generator configured to supply at least one wheel brake of a brake circuit with pressure medium. The pressure generator has a pump inlet valve and a pump outlet valve to control the throughput of the pressure medium. Novel system functions, such as pedestrian protection, require that the pressure generator has a drive with increased power to provide high pressure medium volumes to the wheel brakes at a faster rate. In the case of ABS braking, a high braking pressure generated by the drive works against the starting of the pressure generator and increases the starting current. To ease the starting of the drive and to limit the required starting current, a mechanism is provided downstream of the pump outlet valve which prevents an exerting of the pressure generator on the pressure side with the pressure of the main brake cylinder.

Abstract: The present disclosure relates to a forklift. The forklift according to the present disclosure is controlled such that when a traveling speed reaches or becomes higher than a predetermined traveling speed, pressure of hydraulic oil to be provided to a steering unit is reduced. Therefore, in order to implement a desired direction change, a steering wheel needs to be rotated to a relatively larger degree than when the forklift travels at a low speed. That is, straight traveling performance may be improved by reducing sensitivity of a direction change of the forklift to an operation of the steering wheel.
