摘要： The invention relates to a position indictor for displaying the position of a piston (3) within a cylinder (1) as part of a piston/cylinder arrangement (1, 3) in a braking system. The provision of a Hall element for a hydraulic master cylinder, with the hall sensor mounted on the cylinder and a ring magnet on the piston is known. The aim of the invention is to describe a position indicator of simple construction and which provides the signal relating to the position of the brake pedal relatively rapidly. Said aim is achieved, whereby the Hall element of a Hall sensor (12) is placed in the cylinder wall (12) of the main cylinder and a magnetic region (9) is arranged within the piston/cylinder arrangement such that the Hall element reacts to the piston movement within the cylinder.

摘要： The invention relates to a method and to a device for controlling a motor vehicle comprising an electrically controlled braking system provided with a driving dynamic control. According to the invention, in order to reliably monitor a piston (3) of the main cylinder, even during a driver dynamic control step, and to recognise the driver's wishes over the entire actuation path, the sensor element (36) detects an alteration in the magnetic field when a piston of the main cylinder (1) is displaced and emits a digital signal and an analog signal. The two signals are guided further to an electronic control and regulation unit and are evaluated therein (ESP-ECU).

摘要： The invention relates to a position indictor for displaying the position of a piston (3) within a cylinder (1) as part of a piston/cylinder arrangement (1, 3) in a braking system. The provision of a Hall element for a hydraulic master cylinder, with the hall sensor mounted on the cylinder and a ring magnet on the piston is known. The aim of the invention is to describe a position indicator of simple construction and which provides the signal relating to the position of the brake pedal relatively rapidly. Said aim is achieved, whereby the Hall element of a Hall sensor (12) is placed in the cylinder wall (12) of the main cylinder and a magnetic region (9) is arranged within the piston/cylinder arrangement such that the Hall element reacts to the piston movement within the cylinder.

摘要： The invention relates to a master cylinder (1), in particular for a hydraulic braking system, comprising at least one pressure chamber (3) that is configured in a housing (2) of the master cylinder (1) and at least one container bore (4) for accommodating a hydraulic fluid container (5). According to the invention, a valve (6) is provided with a closing body (7, 24), which can be displaced into an open position or a closed position as a result of a prevailing pressure differential between the pressure chamber (3) and the hydraulic fluid container (5). In the open position, the valve (6) permits a flow (S1) of hydraulic fluid from the hydraulic fluid container (5) to the pressure chamber (3) and in the closed position restricts or prevents a flow (S2) of hydraulic fluid in the opposite direction to the hydraulic fluid flow (S1), from the pressure chamber (3) to the hydraulic fluid container (5). To permit the reduction of the free travel of the master cylinder, in addition to the vacuum filling of the braking system, means are provided, which hold the closing body (7, 24) that is subjected to a closing pressure differential, induced by an evacuation that enables the braking system to be vacuum filled, in the open position and which permit the displacement of the closing body (7, 24) into the closed position, when the brakes are actuated.
