An electrical component assembly suitably prevents electrical components from coming off, while adopting a simple structure of connection by a connection terminal to a control board. The electrical component assembly includes a housing in which the electrical components are assembled, and the electrical components and the housing are fixed to a surface of a base body. The electrical component includes a connection terminal to be press-contacted into a through hole of a substrate of the housing. The electrical component is provided with an electrical component adhesion margin facing said surface of the base body, so as to be fixed to the base body by an adhesive interposed between the base body and the electrical component adhesion margin.

A method for operating a braking assistance system of a vehicle, wherein the braking assistance system assists a braking of the vehicle by a vehicle braking device in the event of a hazard braking. To differentiate between the hazard braking and a normal braking, at least two variables, representing a braking demand of a driver of the vehicle, are ascertained and a threshold value is established for each variable wherein hazard braking is recognized when at least the two variables exceed their particular threshold value, whereupon an automated braking intervention by the braking assistance system is initiated with the aid of the vehicle braking device. Furthermore, at least one driving-situation variable representing the instantaneous driving situation of the vehicle is ascertained and the at least two threshold values are changed depending on the at least one driving-situation variable.

In the event of a malfunction in the supply of hydraulic fluid to the a braking device actuating device a hydraulic system has a manually actuated emergency-operation valve arrangement which is formed in such a way that, after the manual actuation thereof, a fluid connection is created between a steering device actuating device and the a pressure chamber of the braking device actuating device. The emergency-operation valve arrangement has a valve block in which flow paths are formed which can be shut off by means of shut-off screws.

An air system and method includes an air compressor, a temperature sensors, a valve, and a controller. The air compressor is configured to receive filtered air. The temperature sensor is positioned at or near an outlet of the air compressor and configured to sense a temperature at or near the outlet of the air compressor. The valve is operatively connected to an outlet of the air compressor and external to the air compressor. The controller is configured to monitor the sensed temperature at the outlet of the air compressor and control the valve to permit air to flow from the outlet of the air compressor through the valve to unload the air compressor if the sensed temperature exceeds a threshold temperature.
