Definitions
- the invention relates to a hydraulic vehicle brake system having the features of the preamble of claim 1.
- the brake circuits are usually connected via separating valves to a master cylinder and are hydraulically separated from the master cylinder during a slip control by closing the isolation valves.
- the effects of the slip control on the master cylinder, in particular a pulsating brake pedal due to a pulsating promotion of brake fluid by means of a hydraulic pump in each brake circuit, which is usually designed as a piston pump avoided.
- a malfunction of a brake pressure build-up and a brake pressure control by the master brake cylinder during a pressure control by closing the separating valves is avoided.
- Slip regulations are known as anti-lock control, traction control and driving dynamics and skid control, the abbreviations ABS, ASR, FDR and ESP are common. The list is not exhaustive.
- the separation of the master cylinder from the brake circuits of the vehicle brake system by closing the isolation valves has the consequence that a volume of brake fluid is trapped in the master cylinder and because of the incompressibility of the brake fluid as good as no pedal travel or more generally expressed no actuation of the master cylinder is possible.
- the "hard” and almost immobile feeling brake pedal unsettles a driver and complicates the dosage of a pedal force or generally an actuating force, ie a force exerted by the driver for braking muscle power. To make matters worse, that the "hardened” brake pedal regularly occurs in an already critical driving situation when the slip control begins.
- Pedalwegssimulatoren There are therefore known Pedalwegssimulatoren. These are usually spring-loaded hydraulic accumulators, which are connected to the master cylinder and into which the master cylinder displaces brake fluid when it is actuated.
- the pedal travel simulator allows an actuation path on the master cylinder when it is hydraulically separated from the brake circuits by closing the isolation valves.
- a spring element of the hydraulic accumulator generates a pedal force; an at least approximately normal pedal feel is possible, that is to say the usual dependence of an actuation force on the actuation path, as in a brake actuation without slip control.
- the spring action can be done for example by gas pressure, the hydraulic accumulator so be a gas pressure accumulator.
- a simulator valve between the pedal travel and the master cylinder can be provided which separates the pedal travel from the master cylinder and connects with closed isolation valves to the master cylinder. Solenoid valves are used as simulator valves.
- electrohy- draulic vehicle brake systems Another application for a pedal travel simulator is electrohy- draulic vehicle brake systems. These are foreign-vehicle braking systems in which the brake pressure is generated by external energy from a hydraulic pump and the master cylinder is also separated hydraulically from the vehicle brake system by closing a separating valve in each brake circuit. In the event of a malfunction, auxiliary braking with the master brake cylinder is possible by leaving the isolation valves open.
- the hydraulic vehicle brake system according to the invention with the features of claim 1 has a spring-loaded hydraulic accumulator as pedal.
- road simulator which is connected by a simulator valve to the master cylinder.
- the simulator valve has a hydraulic pressure control, it is opened and / or closed by hydraulic pressure of the vehicle brake system.
- the control pressure for the simulator valve is in particular a brake pressure which a hydraulic pump of the vehicle brake system, for example, at a
- the pressure control of the simulator valve according to the invention has the advantage that an electronic control is unnecessary. It does not require a power supply.
- the control is simple and can be made robust and reliable. She is in existing
- Vehicle brake system integrated and allows an at least approximately familiar pedal feel when the braking force is generated by the hydraulic pump instead of the master cylinder and the master cylinder is hydraulically isolated from the vehicle brake system.
- Claim 4 provides a differential pressure valve as a simulator valve or a differential pressure control of the simulator valve.
- the simulator valve is opened by the brake pressure or applied in an opening direction, which generates the hydraulic pump, and it is closed by the master cylinder pressure or applied in the closing direction. If the brake pressure generated by the hydraulic pump is greater than the master brake cylinder pressure, the simulator valve is opened, otherwise it is or remains closed. Open means that the simulator valve the
- Hydraulic accumulator connects to the master cylinder, closed, that the hydraulic accumulator is separated from the master cylinder.
- a differential pressure by which the brake pressure must be greater than the master cylinder pressure to open the simulator valve can be effected.
- the invention will be explained in more detail with reference to an embodiment shown in the drawing.
- the single figure shows a simplified and schematize hydraulic circuit diagram of a hydraulic vehicle brake system according to the invention.
- inventive hydraulic vehicle brake system 1 has a dual-circuit master cylinder 2, to which two brake circuits I, II are connected, of which a brake circuit I is simplified and shown schematically.
- the other brake circuit II is not shown for the sake of simplicity.
- the brake circuit I has a separating valve 3, by which it is connected to the master cylinder 2. By closing the isolation valve 3, the master cylinder 2 is hydraulically separated from the brake circuit I. With a hydraulic pump 4, a brake pressure in the brake circuit I can be generated. Hydraulic wheel brakes 5 are connected to the brake circuit I by wheel brake pressure modulation valve assemblies 6.
- Such Radbremstik- modulationsventilanssenen 6 usually have a Bremstik admitted- and a brake pressure reduction valve, with them a wheel-specific Radbremstikregelung in the wheel brakes 5 is possible.
- wheel brake pressure modulation valve arrangements 6 and their function are known per se and will not be explained in more detail here.
- a wheel-specific wheel brake pressure control takes place to a slip control, for example a Bremsblockierschutz-, a traction and / or a driving dynamics or skid control, for the abbreviations such as ABS, ASR, FDS and ESP are common.
- a driving speed-dependent distance control of a preceding vehicle is also possible.
- Such controls are referred to as Automatic Distance Control (ADR) or Adaptive Cruise Control (ACC). If a slip control is mentioned below, it should also be understood as meaning other brake pressure and wheel brake pressure controls, such as, for example, the aforementioned distance control.
- the not-drawn brake circuit II is constructed in accordance with the drawn brake circuit I.
- the vehicle brake system 1 has a pedal travel simulator 7 which comprises a spring-loaded hydraulic accumulator 8 and a simulator valve 9.
- the simulator valve 9 has a pressure control, it is of a Brake pressure in the vehicle brake system 1 is opened and closed by a master cylinder pressure in the master cylinder 2.
- the pressure control is a differential pressure control, the simulator valve 9 is opened when the brake pressure in the vehicle brake system 1 is greater than the master cylinder pressure; otherwise the simulator valve 9 is closed. Closed means that the simulator valve 9 separates the hydraulic accumulator 8 from the master cylinder 2, opened means that the simulator valve 9 connects the hydraulic accumulator 8 with the master cylinder 2.
- the simulator valve 9 is a pressure control, it is of a Brake pressure in the vehicle brake system 1 is opened and closed by a master cylinder pressure in the master cylinder 2.
- the pressure control is a differential pressure control, the simulator valve 9 is opened when the brake pressure in the vehicle brake system 1 is greater than the master cylinder pressure; otherwise the simulator valve 9 is closed. Closed means that the
- the simulator valve 9 has a shut-off piston 10, which can generally also be held in the form of a slide.
- the shut-off piston 10 has passages 1 1, so that always the same pressure prevails on its two sides and causes no resultant force.
- the shut-off piston 10 is rigidly connected to a piston rod 12 with a control piston 13, both pistons 10, 13 are arranged in a cylinder or a cylinder bore of the simulator valve 9.
- the two sides of the shut-off piston 10 communicate with each other through the passages 11.
- the control piston 13 is double-acting, its one side is acted upon by the brake pressure of the vehicle brake system 1 and its other side is connected to the master cylinder 2, d. H. it is pressurized by the master cylinder 2.
- One side of the control piston 13 is connected to the brake circuit I on a side of the isolation valve 3 facing away from the main brake cylinder 2, for example to a pressure side of the hydraulic pump 4.
- a simulator spring element 17 in the hydraulic accumulator 8 causes a pedal force, so that at least approximately the same dependence of a pedal force of a pedal travel on the brake pedal 16 and thus at least approximately a usual pedal feel prevails with closed isolation valves 3 with open separating valves 3 and closed simulator valve 9, d. H.
- the hydraulic accumulator 8 and the simulated valve 9 having the described differential pressure control form a pedal travel simulator 7, which effects the described, at least approximately normal pedal force / pedal travel dependency on the brake pedal 16 with the isolating valves 3 closed.
- the hydraulic accumulator 8 is connected by a check valve 18 to the master cylinder 2, which can be flowed through in the direction of the master cylinder 2. After loosening the vehicle brake system 1, the simulator spring element 17 displaces any residual brake fluid remaining in the hydraulic accumulator 8 through the check valve 18 into the master brake cylinder 2.
- a second pedal travel simulator 7 is possible on the brake circuit II, not shown, but not required.
