A driver assistance system for automated longitudinal guidance of a motor vehicle includes a sensor system configured to identify an upcoming traffic scene, including locating road users situated ahead of the motor vehicle; and a control unit. The control unit is configured to carry out an automated longitudinal guidance of the motor vehicle depending on the upcoming traffic scene such that, in response to detecting that the upcoming traffic scene is a following-travel standstill situation, the motor vehicle is braked to a standstill at a target stopping distance from a road user situated ahead and identified as a target object. The control unit is also configured to detect a manual request to reduce the predefined target stopping distance. The control unit is further configured to reduce the target stopping distance to a reduced target stopping distance on the basis of the request.

A parking interlock system and method for a vehicle is provided. The system includes: a safety state information detecting unit, configured to detect safety state information of the vehicle; an operating state information detecting unit, configured to detect operating state information of the vehicle; a brake; a motor; a low voltage controller, connected to the safety state information detecting unit and the brake respectively, and configured to generate a safety state judgment result based on the safety state information of the vehicle; and a motor controller, connected to the safety state information detecting unit and the motor respectively, and configured to control the motor according to the safety state judgment result received from the low voltage controller, and to send the operating state information of the vehicle to the low voltage controller such that the low voltage controller controls the brake according to the operating state information.

A rollator is disclosed, including first and second upright members, each including handle portions, wheels, hinges disposed between the wheels and the handle portions, channels disposed along the upright members between the hinges and the wheels, and lateral hinges orthogonal to the hinges. First and second foldable support members having wheels are attached to the hinges. At least one lateral support member is disposed between and attached to the lateral hinges, and includes an intermediate hinge. Brake systems include brake lines communicating between brake controls and brakes. In a reversible storage configuration, the foldable support members are rotated to be at least partially disposed in the channels, and the lateral hinges and intermediate hinge rotate to collapse the lateral support member, bringing the upright members with the folded foldable support members adjacent to one another.

A brake booster includes an input element actuatable by a driver, an actuator for generating a support force, an output element to which an input or support force may be applied and via which an actuating force may be applied to a piston of a brake master cylinder, and a force transmission unit having elastic properties, situated between the input element and the actuator, and the output element, and transmitting the input and/or support forces to the output element. An air gap, which in idle mode is smaller or larger than a desired air gap, is provided between the input element and the force transmission unit. A method for operating the brake booster includes generating a support force prior to a braking intent to be anticipated or immediately after detection of a braking intent, in a time span before or immediately after detection of an actuation of the input element.

A dual input master cylinder, comprising a housing having a first input, a piston base positioned within the housing, and a piston rod having a first end and a second end, the first end of the piston rod abutting the piston base and the second end of the piston rod acting as a second input of the dual input master cylinder, wherein the piston rod is capable of being spaced apart from the piston base

An actuator for a motor vehicle functional unit includes a force transmission unit transmitting an actuating force to an actuating member and being displaced by a measuring travel in a force transmission direction. A force measurement device detects an actual value of the actuating force and includes a spring acting in the force transmission direction, having resilient action counter to which the force transmission unit is displaced and being tensioned by the actuating force over a resilient excursion, a micro switch having smaller switching travel than the measuring travel and being actuated upon displacement of the force transmission unit if the actuating force reaches the actual value, and a stop element for actuating the switch. The switch or element are coupled to or fixed relative to the force transmission unit and the switch and/or element are resiliently supported to compensate for a difference between the switching and measuring travels.

The present invention provides a motor-driven traveling device including: a vehicle body; a motor for travel driving that is capable of braking the vehicle body as a short brake or a dynamic brake; an electromagnetic brake that brakes the vehicle body, separately from the motor; an operation switching circuit that switches between causing the motor to perform travel driving and causing the motor to perform braking; a brake release switch that receives an operation pertaining to brake releasing of the motor and the electromagnetic brake; and a brake control circuit that, while the brake release switch is operated, controls the motor and the electromagnetic brake in response to the operation on the brake release switch.
