Embodiment Construction

[0029] The vehicle brake system comprises, in addition to the wheel brakes, valves (inlet valves, outlet valves, separation valves and switchover valves) which are connected to the wheel brakes by means of pipes and hose lines (inlet valves, outlet valves, separation valves and switching valves to create a change in the suction line of the pump to generate pressure in at least one wheel brake) hydraulic unit with integrated return pump or pressure boost pump and pedal-operable master cylinder 1, said master The cylinder has first and second pistons 2, 3 for first and second pressure chambers 4, 5, wherein the pistons 2, 3 are movably arranged inside the housing 6 to be contained in pairs in the brake The wheel brakes in the circuit supply the pressure medium. It is understood that a brake booster for generating the servo force can be arranged upstream of the master cylinder 1 , although in principle this can also be achieved by other sources of pressure increase, for example a...

Abstract

The invention relates to a device for monitoring the position and movement of a brake pedal, comprising a master cylinder with an integrated position detector for monitoring the position of a movable piston in a housing, in particular for use with a driving dynamics regulation In the controlled braking system of a motor vehicle of the device, wherein the position detector has a magnet as a signal generator, which emits a magnetic field in the direction of a sensor element, which is fixedly arranged on the housing and Can be connected to an electronic control unit. In order to monitor the pressure rod piston during driving dynamics regulation, it is proposed to arrange the magnet between two pistons and to displace it relative to at least one piston. During braking, the magnet can be displaceable relative to the piston if the piston is immovable relative to the housing due to the closing of the separation valve during driving dynamics regulation.

Description

Background technique [0001] Devices for monitoring the position and movement of a brake pedal are known in principle. [0002] A pedal-operable master cylinder is known from WO 02 / 43996 A1, said master cylinder being provided with an integrated position detector so that the position of a first movable piston located inside the cylinder housing can be monitored , so that it can be used in a controlled braking system of a motor vehicle, wherein the piston has a magnet as a signal generator, which emits a magnetic field in the direction of a sensor element, which is fixedly arranged in the housing physically. [0003] Such a sensor arrangement is designed for a driver-initiated braking process during normal operation, during which the piston to be monitored travels through a defined actuation path. The magnet is acted upon by a spring element which is supported at the ends on the housing bottom and is thus supported on a stationary component relative to the pressure rod piston....
