Definitions
- Pressure generator to carry out a test operation a setpoint is specified.
- the invention also relates to a device for operating the braking system described above with a control device which is designed to specify the setpoint value for carrying out a test operation.
- the invention also relates to a brake system with such a device and a
- Today's brake systems also have a master brake cylinder that can be actuated by a user in particular by means of a brake pedal
- External power braking system that can initiate or carry out a braking process independently of the user.
- an external power brake system has an in particular electrically controllable one Pressure generator which, if necessary, generates a hydraulic system pressure in the brake system independently of the brake master cylinder.
- the pressure generator is usually operated by an electric motor and has
- the master brake cylinder and pressure generator can then expediently be interconnected by one or more valves with the hydraulic circuit of the brake system, so that the system pressure is solely through the
- Master cylinder can be generated solely by the pressure generator or jointly by the master cylinder and pressure generator, in particular without the pressure generation of one having a negative effect on the pressure generation of the other.
- friction brakes are used which are connected to the hydraulic circuit that provides the system pressure by a controllable proportional valve. By activating the proportional valve, the pressure acting on the respective friction brake is set.
- Preset pressure generator a target value, for example, to determine on the basis of sensor data whether the pressure generator is functioning as expected.
- the method according to the invention with the features of claim 1 has the advantage that the development of noise caused by the test operation and wear on the pressure generator are minimized. At the same time, vibrations generated by the test operation, which can affect the rest of the hydraulic circuit or the rest of the brake system, are reduced, which also protects other components of the brake system.
- the target value is specified in a smoothed manner by a logistic growth function.
- the logistic growth function ensures that the setpoint is not specified in a jerky manner, but rather gently rising and gently stagnating, so that a jerky one Moving or actuating the pressure generator is avoided.
- y (t) is the setpoint at time t
- y (t - At) is the setpoint at time t
- a very small value compared to the jump height K is selected as the start value y (0), in particular 1% or less of the jump height K. This ensures that a gentle start-up of the pressure generator or an initially slow pressure increase in test mode he follows.
- a value between 0.05 and 0.0005, in particular between 0.04 and 0.001, in particular 0.04 or 0.001, is particularly preferably set as the start value y (0). This results in an advantageous behavior of the pressure generator in test mode.
- the start value can optionally be adapted to boundary conditions.
- the growth rate R is preferably set to a value between 0.7 and 0.1, in particular between 0.6 and 0.2, particularly preferably 0.6 or 0.2. As a result, the setpoint is reached within a sufficiently short time without the pressure generator moving suddenly.

- the motor vehicle according to the invention with the features of claim 8 is characterized by the brake system according to the invention.
- Figure 1 shows an advantageous braking system of a motor vehicle in a
- FIG. 2 a first diagram
- Figure 3 shows a second diagram
- FIG. 4 shows a third diagram, each to explain an advantageous
- FIG. 1 shows a schematic representation of a brake system 1 for a motor vehicle 2, not shown here.
- the brake system 1 has a brake pedal 3 actuatable by a master cylinder 4, which as
- Tandem master brake cylinder is designed and in this respect has two hydraulic pistons 6 and 7 mounted axially displaceably in a cylinder 5.
- Hydraulic pistons 6, 7 together with the cylinder 5 each form pressure chambers 8 and 9, which are each hydraulically connected to a brake circuit 10, 11 by a controllable circuit isolating valve 12, 13.
- Each brake circuit 10, 11 in the present case has two friction brakes LR, RF and LF, RR, respectively, which can be hydraulically actuated.
- An inlet valve 14_LR, 14_RF or 14_LF and 14_RR are connected upstream of the friction brakes LR-RR and a controllable outlet valve 15_LR, 15_RF or 15_LF and 15_RR is connected downstream to increase the hydraulic pressure made available by the master brake cylinder 4
- the input valves 14 are all designed as proportional valves, so that different ones depending on their activation
- Flow cross-sections are adjustable in order to adjust the hydraulic pressure acting on the respective friction brake LR-RR as required.
- the inlet valves 14 are preferably activated in a pulse-width-modulated manner.
- Outlet valves are preferably designed as switching valves, optionally as proportional valves, and can be controlled with pulse width modulation.
- the outlet valves are on the outlet side with a tank 16 for receiving and providing the
- Hydraulic medium of the brake system 1 connected.
- the brake system 1 has a
- External power brake device in the form of an electric motor controllable pressure generator 17.
- This has a piston 19 which is mounted in a cylinder 18 in a radially sealing and axially displaceable manner and which can be driven by an electric motor 20.
- the piston 19 encloses a further pressure chamber 21 which can be connected to the brake circuits 10 and 11 by switching valves 22 and 23 between the separating valves 12 and 13 and the inlet valves 14.
- the pressure generator 17 is controlled by the control device 24 to generate a hydraulic pressure in the brake system 1, which is generated in particular by one or more pressure sensors 25 and optionally when one or more of the inlet or outlet valves 14, 15 or also switching valves 12, 13, 22, 23 is monitored to determine whether the hydraulic pressure is behaving as expected and thus the
- Isolating valves 22, 23 are open.
- control device 24 is designed to predefine the setpoint value of the hydraulic pressure provided by the pressure generator 17 for a test process in a smoothed manner using a logistic growth function.
- FIG. 2 shows the plotted over time t in a diagram
- FIG. 2 shows a first characteristic curve Kl, which the
- Control unit 24 shows smoothed setpoint specification in comparison to a conventional characteristic curve K, which shows abrupt setpoint specification, as is known from the prior art.
- the logistic growth function ensures that the piston slowly accelerates and decelerates so that jerky movements of the piston 19 are avoided.
- the jump height and the growth rate are selected in particular as a function of the structure of the brake system 1 in order to enable optimal control of the pressure generator 17 in the test principle.
- FIG. 3 shows the volume flow V in plotted over time t
- FIG. 4 shows two further characteristic curves which differ in relation to the previous exemplary embodiment according to FIG. 3 by different growth rates R.
- a final target value of 4 cm 3 / s is set. Due to the different growth rates and starting values, the logistic growth function ensures that the piston 19 does not move jerkily.
- the starting value y (0) is selected to be much smaller than the jump height K, for example 1% or less, so that here a starting value y (0) of between 0.05 and 0.0005, in particular between 0.04 and 0.001, or in particular of 0.04 or 0.001 results.
- values between 0.7 and 0.1, in particular between 0.6 and 0.2 are selected as the growth rate R.
- the growth rate is particularly preferably set to 0.6 or 0.2 by the control device 24.
- the values are selected in particular as a function of the brake system 1 and its components.
- the advantageous procedure ensures that, by avoiding jerky movements, the generation of noise by the pressure device 17 and vibrations introduced into the brake system 1 are minimized, which reduces wear on the pressure generator 17 and other components of the brake system 1 and thus reduces the service life of the pressure generator 17 and the Brake system 1 can be increased overall. In addition, incorrectly activated driver warnings and system degradation due to the reduced wear and tear are avoided.
