- a control line 50 opens into a space 47, which lies behind the booster piston 41.
- a push rod 46 of the brake pedal 26 penetrates the amplifier 7, which enables the THZ 11 to be actuated in an emergency if the amplifier 7 should fail. This emergency operation corresponds to the emergency operation of a vacuum brake booster.
- booster piston 41 and THZ area in conjunction with the pressure made available by a high-pressure source, gives the THZ pressure to be achieved with reinforcement. It is envisaged to achieve a corresponding structural design of the surface conditions and / or to achieve the maximum requested pressure Design high-pressure accumulator for a corresponding maximum pressure to be stored.
- a hydraulic high-pressure accumulator is preferably used as the high-pressure source, which supplies a pressurized brake fluid, ie “charged 1 ”, by means of a hydraulic pump.
- a return pump already present in the system is advantageously used for charging a accumulator.
- the store is loaded after braking, for example when the hydraulic pressure in the store reaches less than 40 to 50 bar, which corresponds to a brake pressure (modulation pressure) of 80 to 90 bar.
- a charging time of approx. 2 to 3.5 seconds is required by the pump until an upper limit value for the hydraulic pressure in the accumulator from 50 to 70 bar, corresponding to an actuation pressure of 100 to 110 bar, is reached.
- the hydraulic accumulator empties completely, then the pump needs approx. 30 to 40 seconds to refill the hydraulic accumulator up to a hydraulic pressure of 50 to 70 bar.

- the structure and function of the second brake circuit for the two other wheel brakes is identical to the brake circuit shown and therefore need not be described in more detail.
- the brake circuits are acted upon by the master cylinder (THZ) 11, which is supplied with hydraulic fluid (hydraulic fluid) via a hydraulic reservoir 13.
- the master cylinder 11 is actuated via the hydraulic brake booster 7 described above.
- the pressure requested by the respective control or regulation of an electronic unit 28 is generated via the hydraulic amplifier 7 and the master cylinder 11.
- the wheel brakes 30, 31 are supplied with pressure by normally open (SO) valves 15.1 and 15.2 directly from the THZ 11 via a line 14, an SO isolating valve 9 and subsequent lines 14.1 and 14.2, the THZ 11 via the hydraulic amplifier 7 is actuated, which can be acted upon by a pressure source 4, 19, 20 with hydraulic pressure.
- SO normally open
- Brake pressure is reduced via a return line 17 and normally closed (SG) valves 16.1 and 16.2, a low-pressure accumulator 18 and the pump.
- SG normally closed
- the charge of a high-pressure accumulator 4 is carried out by the valve 2 which is open when de-energized.
- the pressure in the high-pressure accumulator is below one Predetermined setpoint, in particular below 50 bar to 70 bar, falls, brake fluid is sucked in from the THZ 11 via the open changeover valve 8 and by means of the pump 19 operated with the motor 20.
- the brake fluid is pumped into the high-pressure accumulator 4 via a check valve 23 connected to the pressure side 21 of the pump 19, a damping chamber 57, via a line branch 22 and a line 24 into which the valve 2 and a pressure sensor 3 are inserted.
- the motor 20 is controlled until a predetermined target pressure is reached.
- the pressure is measured by a pressure sensor (pressure sensor 3).
- valve 5 When filling the high-pressure accumulator 4 (accumulator charging), the valve 5 arranged in a line 50 between the high-pressure accumulator 4 and the amplifier 7 is closed.
- the pressure side of the pump is also connected to the wheel brakes 30, 31 via the branch 22 and an adjoining line 25, into which a valve 1 is inserted.
- Valve 1 is preferably closed when de-energized (SG valve) and valve 2 is open when de-energized (SO valve). Then these valves are not energized during the store charging, advantageously only the changeover valve 8 then being energized for filling.
- valves 1 and 2 By switching valves 1 and 2 during normal brake pressure control, as in the case of ABS or ESP control, control in a closed hydraulic system is possible. Media separation is thus ensured, which brings advantages in the event of a high-pressure accumulator which may gas out.
- the boost pressure of the high-pressure accumulator is designed depending on the design, the booster and the desired TH pressure.
- valve 1 as an SO valve and valve 2 as an SG valve, with the switching states then having to be reversed accordingly.
- the charging process is preferably carried out in phases in which the engine load of the drive motor or a variable representing the engine load, such as
- Throttle valve position and / or accelerator pedal position approximately constant or with an increasing gradient.
- a steeply decreasing gradient of the engine load interrupts the charging process.
- no charging process is carried out or ongoing charging processes are interrupted.
- charging processes of the high-pressure accumulator are permitted if no other control functions, e.g. a brake intervention of a higher-level control system, such as distance and follow-up control (ACC system), is engaged.
- a brake intervention of a higher-level control system such as distance and follow-up control (ACC system)
- the charging process of the high-pressure accumulator 4 is stopped immediately.
- the braking detection takes place via a pedal travel sensor 60 or by means of another sensor which detects the driver's braking request. If a braking request is detected by the sensor system 60, the valve 5, which is preferably to be operated in an analog manner, is opened accordingly depending on the travel path of the push rod 46 of the brake pedal 24 and / or the actuation speed, so that brake fluid from the charged high-pressure accumulator 4 into the space behind the booster piston 47 can flow.
- the build-up of the pressure in the amplifier 7 is monitored by the pressure in the THZ using a pressure sensor 10. This means that a certain path is assigned and regulated to a certain pressure in the THZ.
- the booster piston 41 moves in front of the push rod 46 of the brake pedal 26, which is increasingly penetrating into the booster chamber, without any contact being made or having to be made. It is preferably provided to provide an elastic means, in particular a spring, between the push rod 46 and the booster piston 41 in order to achieve an elastic coupling.
- valve 6 which is also preferably to be operated analogously, is opened in a line 12 between the high-pressure accumulator 4 and the container 13, corresponding to the withdrawal of the driver's request, and the Brake fluid can flow back into the reservoir 13.
- the valve 6 By preferably designing the valve 6 as an SO valve, it is possible to actuate the amplifier in the event of a system failure, without negative pressure being generated in the amplifier 4 (or in the amplifier chamber 47), because volume compensation takes place via the valve 6.
- the driver only has to overcome the additional force which is generated by the pressure already set in the booster 7. This Additional force is only dependent on the surface of the push rod 46 that penetrates into the amplifier 7.
- the method according to the invention and the combination of the hydraulic booster and the auxiliary pressure source with high-pressure accumulator 4 can be designed such that the entire required brake pressure is generated by the booster. However, this increases the required storage pressure in the high-pressure accumulator 4.
- Control pressure to provide (similar to a vacuum brake booster). This already covers a large area of all braking operations, e.g. all "normal braking” in a range from a maximum of up to 60 to 80 bar resulting brake pressure, from the braking, which is a brake pressure above this control point
- the modulation point is determined by the ratio of accumulator pressure to THZ pressure and the ratio of booster piston area to THZ piston area.
- the described method is advantageously suitable for electronic brake control systems, such as ABS (anti-lock braking system), EDS (electronic differential lock, traction control), ESP (electronic stability program), or HDC (hill descent control, downhill regulation). It can also be used for systems with distance and follow-up control (ACC, Adaptive Cruise Control), since the THZ automatically balances the pressure in the circuits.
