Device for activating braking installation of motor vehicle, has additional displacement sensor activated separately from displacement sensor, where activation of displacement sensors is carried out by two movable elements

摘要

The device has an additional displacement sensor activated separately from a displacement sensor, where the activation of the displacement sensors is carried out by two movable elements with respect to each other. The activation of the displacement sensors is carried by an elastic mechanism or spring mechanism e.g. spring washer (105), where the displacement differences or force difference of the sensors are measured and treated by a data processing unit. An activating device comprises a cylinder whose piston (103) is activated by activating mechanisms (101, 102). An independent claim is also included for a method for monitoring operation of a displacement of a displacement simulator.
