Definitions
- the invention relates to a by-wire brake actuation device for actuating a motor vehicle brake system, with a simulator which can be actuated by means of a brake pedal, a signal from an actuation sensor being supplied to an electronic control which controls a pressure source as a function of the signal, and an output of the pressure source having a distribution device for the braking force is connected, and actuates wheel brakes, and with means for enabling a muscle-powered brake actuation within a fallback level.
- a generic brake 'multiplexing frame generating apparatus has been proposed as part of an electrohydraulic brake system (EHB).
- EHB electrohydraulic brake system
- the device is based on a hydraulic decoupling of the brake pedal from the hydraulic reaction forces of the brake system, in that electromagnetic isolation valves are provided which hydraulically separate a master brake cylinder from the brake system.
- the brake pressure in the wheel brakes is controlled electronically (by-wire) in that the signal from the actuation sensor, which is designed, for example, as a pedal travel sensor, is supplied to an electronic control unit and, after data processing, to an electro-hydraulic hydraulic unit (HCU) with electromagnetic valves, so that in Depending on the output signal of the HCU, using the pressure source, individual or all wheel brakes can be subjected to a suitable brake pressure.
- HCU electro-hydraulic hydraulic unit
- BESTATIGUNGSKOPIE State is operable, one uses a so-called hydraulic - since de-energized - fallback level, within which the brake actuation is guaranteed using an elaborate safety concept.
- Various sensor signal evaluation processes enable partial shutdowns of certain functions such as brake assist,
- an idle path (a) is provided between an actuation component such as a brake pedal or a component articulated on a brake pedal and a further actuation component connected downstream in the power flow, in order to mechanically relieve the brake pedal in a by-wire mode Decouple motor vehicle brake system.
- the actuating component is of split design, and the two parts are at a distance a from one another, so that the power flow is interrupted.
- the invention enables a surprisingly simple by-wire brake actuation device with unlimited functionality. Until the hydraulic / mechanical fall-back level is reached, only the free travel a has to be overcome before the brake pressure builds up in the wheel brakes. In other words In by-wire mode, ensure that there is always a sufficient distance a from the mechanical decoupling of the brake pedal.
- a means is provided to automatically reduce the free travel after exiting the by-wire mode and at the beginning of a muscular force-operated brake actuation.
- the means can be controlled, for example, by means of an electrical, an electromagnetic, a hydraulic, pneumatic or also pyrotechnic actuator, which automatically switches to a closed position to reduce the free travel when the signal changes or when there is no current supply. In the closed position of the actuator, the distance a is reduced or bridged to a certain extent. The free travel a is therefore no longer to be overcome, so that even the fallback level offers a direct braking feeling.
- externally actuated states are possible in the by-wire mode due to the distance a maintained, without passing on any direct force reactions to the vehicle driver.
- the simulator reserves the right to generate them.
- the means is provided as a coupling between two actuation components.
- the coupling can have a block-shaped body, which has, for example, a wedge shape, and is provided as a slide which can be brought into the free travel a between the actuating components in a form-fitting manner and therefore bridges the free travel.
- the coupling can be a spring for elastic prestressing of the block-shaped body and an electromagnet for returning or Have retention of the block-shaped body in the open position. By using the spring to close the power flow, the clutch automatically strives to the closed position when de-energized.
- a clutch is preferably provided which, by means of a command to mechanically couple the brake pedal to the actuation component, in particular in the event of a failure of the booster, directly mechanically couples the brake pedal to the downstream actuation component in its position at the time of the actuation request.
- the point of application of the brake pedal is not brought up to the point of application of the actuating component in its longitudinal direction, but the brake pedal acts directly on the point at which the actuating component is currently located. This can be done, for example, by means of a radially moving claw or the described wedge, which connects the two actuating components in the position in which they are currently located.
- the brake pedal is connected to a clutch shaft rotatably mounted in its longitudinal direction as an actuating component which, depending on its relative rotational position to a downstream actuating component, is either longitudinally displaceable in the actuating direction relative to the latter, or is non-displaceably engaged in the axial direction
- the coupling shaft and the actuating component are provided with projections lying one behind the other in their longitudinal direction, with the projections of the coupling shaft and the actuating component except in a first rotational position of the coupling shaft relative to the actuating component Are engaged and wherein at least one projection of the coupling shaft is in engagement with a projection of the actuating component in a second rotational position.
- the coupling shaft is connected to a downstream one
- Actuating component provided open longitudinal bore into which an end of this actuating component protrudes and that lateral surfaces of the end of the actuating component and the longitudinal bore in the coupling shaft carry the projections.
- the clutch is provided with a spring which is supported with its first end on a housing of the clutch and with its second end on a transmission member, the transmission member being connectable to the clutch shaft rotatably mounted in its longitudinal direction, the clutch shaft against the Transmission member depending on its rotational position relative to the transmission member is longitudinally displaceable or in engagement with the transmission member in the axial direction via projections.
- the coupling shaft is in at least a first rotational position in engagement with the actuating component and out of engagement with the transmission member and in at least a second rotational position out of engagement with the actuator and in engagement with the transmission member.
- a particularly simple mechanical coupling between the downstream actuation component and the brake pedal is achieved in that the brake pedal is connected to a clutch shaft which is rotatably mounted in its longitudinal direction and which can be displaced longitudinally against the actuation component depending on its rotational position relative to the actuation component or with the actuation component in the axial direction is engaged. There is therefore no radial or axial movement of a coupling member, but a rotational movement that is easier to achieve mechanically.
- both the coupling shaft and the actuating component are provided with projections lying one behind the other in a row in the longitudinal direction thereof, the projections of the coupling shaft and actuating component being in a first rotational position of the coupling shaft relative to the actuating component are disengaged and, in a second rotational position, at least one projection of the coupling shaft engages with a projection of the actuating component.
- a plurality of rows of projections are provided at a predetermined angular distance over a circumference of the actuating component and the coupling shaft.
- the clutch shaft is used to transmit the force from the brake pedal to the actuating component.
- the coupling shaft is provided with a longitudinal bore which is open towards the actuating component and into which one end of the actuating component protrudes and that lateral surfaces of the end of the actuating component and the longitudinal bore in the coupling shaft carry the projections , The actuating component and the coupling shaft are thus guided in a longitudinally displaceable manner.
- a corresponding force transmitter for example a spring or a motor, which act in a suitable manner on the brake pedal against its direction of actuation.
- the clutch is provided with a compression spring which is supported with a first end on a housing of the clutch and with a second end on a transmission member, the transmission member having the clutch shaft rotatably mounted in its longitudinal direction is connectable, wherein the coupling shaft against the transmission member depending on its rotational position relative to the transmission member is longitudinally displaceable or in engagement with the transmission member in the axial direction.
- the clutch shaft in at least a first rotational position in engagement with the actuation component and out of engagement with the transmission member and in at least a second rotational position out of engagement with the actuation component and in engagement with the transmission member.
- the clutch shaft connected to the brake pedal thus acts either only on the compression spring in the normal case or only on the actuating component in the fallback level.
- a wide variety of devices can be used as the pressure source.
- a hydraulic amplifier with at least one hydraulic pump can be provided, which can be controlled by electrical signals in the by-wire mode.
- the wheel brakes are actuated depending on muscle strength and hydraulically via a master brake cylinder.
- the pump feeds a high-pressure accumulator in order to enable a pulsed pressure delivery of the pump, which is basically inertial.
- the pressure source has a pneumatic amplifier and additionally a hydraulic pump, which is activated, for example, if the pneumatic amplifier is defective or if the amplification is insufficient.
- a so-called active - i.e. H. externally controllable - pneumatic amplifier can be provided, which can be controlled by electrical signals in the by-wire mode and mechanically by the actuation components in the fallback level.
- individual positions of the brake pedal can be assigned to an associated position of the downstream actuating component and thus in particular to the position of the diaphragm plate of the pneumatic amplifier.
- the brake pedal travel can be shortened and the free travel can be made as small as necessary.
- only slight movements of the brake pedal-side actuation component from its zero position can be assigned to sufficient displacements of the diaphragm plate and thus of the actuation component of the amplifier. In other words, a sufficient distance a is generated in each case.
- OHBV vacuum brake booster
- the differential pressure in pneumatic booster pressure chambers and, in addition, the hydraulic brake pressure generated in the brake system by the pneumatic booster are measured using a suitable sensor system and compared with a driver's request.
- the driver's request can be tapped, for example, via the actuation position of the brake pedal. If, however, the measured brake pressure deviates sufficiently from the driver's request, a hydraulic pump or another organ is activated to compensate for the pressure deficit.
- the vacuum brake booster, the master brake cylinder or the downstream distribution device is provided with a suitable sensor, for example a pressure sensor in the master brake cylinder, the system pressure can also be determined in this way and the OHBV function can be enabled.
- sensors can be used which, for example, determine a displacement of a diaphragm plate by means of a displacement sensor, or by using a pressure sensor to determine a pressure on an elastic editorial element (reaction disk) of the amplifier.
- the signal from the displacement sensor can be used to enable a brake assist function (BA).
- the reaction exerted by the simulator on the brake pedal can be set as desired as a function of the gain of the booster or the output pressure of the master cylinder due to programming.
- the pump can start when the outlet pressure is too low or the setpoint cannot be reached by increasing the reaction force of the pump Simulator on the brake pedal to be reported to the driver (for example, by pushing back harder).
- the possibility of programming the desired amplifier output depending on the position of the brake pedal means that the brake pedal feel or the overall gain (sum of, for example, vacuum brake booster effect and additional amplifier effect) can be adapted as desired.
- the amplification ratio output force in relation to the input force
- the amplification ratio can be kept low at lower braking forces in the sense of better controllability, while a high amplification ratio can be selected at medium braking forces, which is then gradually reduced when the brake servo is at the control point (saturation) to avoid a sharp kink and dosage problems.
- a particularly great advantage of the invention is achieved in that in the event of the failure of electrical control signals of an active vacuum brake booster, in particular in the event of a power failure of the brake actuation device, the booster can be controlled directly mechanically, so that there is a secure fallback level in the event of the electronics failing.
- the booster works pneumatic booster like a conventional pneumatic brake booster, with hydraulic boosters the hydraulic transmission ratio in the master brake cylinder comes into action.
- a grading of the fallback levels can also be provided. If, for example, one of two brake circuits fails, the amplification can be set up so that a higher brake pressure is supplied to the intact brake circuit. If the vehicle is in the limit range of driving stability, the use of anti-skid measures such as anti-lock braking system (ABS) or electronic stability program (ESP) is recommended.
- ABS anti-lock braking system
- ESP electronic stability program
- the failure of a brake circuit will trigger a warning to the driver through the above-mentioned display elements.
- the brake actuation device can also be used with great advantage for ESP functions. Since the ESP functionality is based on a speed that jeopardizes driving stability and requires wheel-specific actuation without a braking request, a particularly fast pressure coil on selected wheel brakes is important. This is ensured according to the invention by connecting a separate amplifier, such as in particular a pneumatically operating amplifier, a hydraulic amplifier or some other means. The conditions are somewhat comparable to a traction control system (ASR) within which traction slip is to be reduced by braking and, if necessary, engine intervention.
- ASR traction control system
- the brake actuation device also allows the booster to be dependent on others, regardless of the position of the brake pedal lever occurring parameters can be controlled, such as ABS, ESP, intelligent speed control (ICC), ASR and other signals that are triggered by the driving state of the vehicle or a driver request such as starting on a mountain.
- ABS ABS
- ESP intelligent speed control
- ASR automatic speed control
- a displacement or angle of rotation sensor on the brake pedal is sufficient to determine the driver's request, and the displacement sensor described to determine the position of the membrane plate and its deviation for the purpose of regulating the amplifier or to determine the OHBV case, as well as a hydraulic pressure sensor in at least one brake circuit for determining the actual value in the brake system and for determining the deviation of the actual value from the driver's request, taking safety measures and the OHBV mode into account. If a so-called force feedback pedal is used, the force feedback actuator can
- a rotation angle or displacement sensor can be assigned so that a total of two rotation angles or displacement sensors are provided in the pedal area, the signals of which are fed to the central control unit.
- a pneumatic brake booster can also have a pneumatic pressure sensor or differential pressure sensor, which senses the pneumatic pressure or a pressure difference between pneumatic chambers.
- the electronic Control unit capable of detecting a malfunction such as air inclusion or circuit failure in a brake circuit or the entire brake system and triggering suitable countermeasures, such as the fallback level in particular.
- the above-mentioned sensors allow the control point of the amplifier or an insufficient vacuum in a vacuum chamber to be recognized and the hydraulic pump to be started via the electronics unit for additional amplification.
- the invention enables mechanical decoupling of the brake pedal. Since the invention presupposes that the amplifier can be controlled mechanically not only in the fallback level via the brake pedal, but in the by-wire mode by means of an electrical actuation sensor signal, it is always possible by appropriate programming, the amplifier by suitable amplification to control the electrical signal such that its actuating component runs ahead of the mechanical point of application of the brake pedal at a predetermined distance a.
- the actuation sensor signal is dependent on the position of the brake pedal, so that with a certain displacement of the brake pedal the amplifier is also actuated by a predetermined amount and thus takes its actuation component with it by a corresponding distance. This path is now chosen so that between the mechanical point of application of the brake pedal on
- Actuating component and the actuating component itself always remains a certain distance a, which leads to mechanical decoupling between the brake pedal and actuating component.
- the brake systems mentioned above are generally based on the electrohydraulic principle in relation to all wheel brakes.
- the invention can also be used with particular advantage in so-called hybrid systems in which, for example, a pair of hydraulic wheel brakes are provided for a front axle and a pair of electromechanical actuators for a rear axle.
- Such systems can even be represented on the basis of a 12 (14) volt electrical system structure, and have the advantage that the hydraulic wheel brakes of the front axle can nevertheless be actuated directly in the event of a power failure in a fallback level.
- Fig. 1 shows a first embodiment of a
- Brake actuation device with vacuum brake booster in an unactuated state 2 shows the brake actuation device according to FIG. 1 in the working state
- FIG. 4 shows a section through the embodiment according to FIG. 3,
- FIG. 8 shows an application of a brake actuation device in a hybrid brake system.
- the 1 has a brake pedal 1 which is provided with a simulator 2.
- the simulator 2 has at least one, preferably two redundantly provided actuation sensors 3, the output signals of which are fed to an electronic control 4 (ECU).
- the brake pedal 1 can be mechanically coupled to the amplifier 6 via an actuation component 5 of a pneumatic amplifier 6.
- actuation component 5 Such a connection is common in the known pneumatic amplifiers 6, since they are mechanically controlled analogously by the brake pedal 1 via the actuating component 5.
- the electronics unit 4 fails, such a control is also possible with the brake actuation device according to the invention and forms a safe fallback level.
- the amplifier 6 can also be electrically controlled by an output signal of the electronic circuit 4 via a connection 7. This is done using a magnetic drive 8, which acts on the actuating component 5 and which is supplied with current signals via the connection 7.
- a distribution device 10 of the brake actuation device includes a master brake cylinder 11 with an associated container 12 and a valve circuit 13, which is optionally provided with a pump or a pump motor 14. Wheel brakes 16 are actuated from outputs of the valve circuit 13.
- the amplifier 6 is provided with a displacement sensor 17, while the master brake cylinder 11 has a pressure sensor 18 at its output.
- the simulator 2 can be designed mechanically and, for example, have a spring.
- Reactive force is exerted on the brake pedal 1. This enables the driver to dose the effect of the brake in a known manner as a function of the force, even if the brake pedal 1 (in the by-wire mode) is mechanically decoupled from the brake system.
- the actuation sensor 3 emits a signal to the electronics unit 4, which describes the angular position of the brake pedal 1.
- the magnetic drive 8 is actuated by a corresponding program stored in the electronic control 4 as a function of the output signal of the actuation sensor. This corresponds to a certain mechanical input force on the actuating component 5, as it is exercised by the brake pedal 1 in the usual amplifiers 6.
- a corresponding movement of the actuating component 5 can be assigned within wide limits via the electromagnetic drive 8 to a movement of the brake pedal 1. This movement is selected such that the actuating component 5 maintains a sufficiently small distance a from the brake pedal so that the actuating component is mechanically decoupled from the brake pedal 1.
- the path actually covered by a membrane plate 29 of the amplifier 6 can be determined, whereby the amplifier 6 can be regulated to the desired value. If this measured path permanently deviates sufficiently from the path specified by the electronics unit 4, for example due to a failure or an error in the braking system, an error signal is reported which triggers suitable processes in the braking system.
- the pressure sensor 18 acts in or at the output of the master brake cylinder 11 in a corresponding manner.
- An electromechanical actuator for generating the brake pedal simulation force detects the driver's request by means of suitable sensors 3 and transmits this to the ECU 4, which in turn controls the externally controllable amplifier 6.
- the amplifier 6 runs faster in the direction of the master brake cylinder 11 than the brake pedal 1, so the simulator 2 generates a counterforce to the driver's foot force via the motor 19 and the driver is decoupled under normal circumstances like in a "brake-by-wire" system.
- the input force characteristic and the deceleration behavior are freely and independently programmable. Fall ECU 4 or Simulator 2 off, the system can be operated like a conventional brake system.
- FIGS. 3 and 4 show a clutch 20 with a simulator function at the same time, the actuating component 5, which can be used to actuate the amplifier 6, which can be actuated both electrically and mechanically, or to actuate the master brake cylinder 11 or a tandem master brake cylinder.
- the position of the actuation component 5 can be changed by control signals from the ECU 4, which is due to signals from the actuation sensor. This can take place, for example, in that the amplifier 6 is activated as a result of the signals from the actuation sensor or in that the master brake cylinder 11 is consequently acted upon by the pressure increase in a hydraulic pump, the pump in turn being activated by the ECU 4.
- the position of the actuation component 5 thus depends on the output signal of the actuation sensor.
- the output signal of the actuation sensor is in turn dependent on the position of the brake pedal 1. A displacement sensor required for this is not shown in FIG. 3.
- the clutch 20 shown in FIG. 3 creates the possibility of either mechanically coupling the brake pedal 1 to the actuating component 5 or of canceling this coupling. It is important that the actuating component 5 and a coupling shaft 21 of the coupling 20 are connected to one another during the transition to the mechanical coupling in the mutual axial position in which they are currently when the command for the mechanical coupling occurs.
- a lateral surface 35 of one end of the actuating component 5 is provided with rows 22 of projections 23 lying one behind the other, the rows of which correspond 31 of projections 30 on a lateral surface 24 are assigned to a longitudinal bore 25 in the coupling shaft 21.
- These rows 22, 31 are evenly distributed on the surface both on the outer surface 24 and at the end of the input member 5 at equal angular intervals.
- the distances between the projections 23, 30 are selected such that, with the corresponding rotational position of the actuating component 5 and the coupling shaft 21, the projections 23, 30 of the components mentioned can lie flush with one another.
- the projections 23, 30 of the actuating component 5 and the coupling shaft 21 are undercut, so that these two components are coupled to one another in the axial direction.
- the projections 30 of the coupling shaft 21 lie in the regions of the actuating component 5 which are free of projections 23 and lie between the rows 22, so that the two components in this position in the longitudinal direction are not linked.
- the coupling can take place by means of suitable projections 33, 34 on an outer lateral surface of the coupling shaft 21 and on an inner lateral surface of the transmission member 26, as in connection with Push rod and clutch shaft was discussed above. If the coupling shaft 21 is mechanically connected to the transmission member 26 in the longitudinal direction, a bracket 27 of the transmission member 26 acts on a spring 28 which is supported on a housing 32 of the clutch 20 and as a result of which the desired simulator force is exerted.
- the clutch shaft 21 is rotated by a suitable amount with respect to the input member 5, as a result of which the clutch shaft 21 is coupled to the actuating component 5, but is decoupled from the transmission member 26.
- the projections 23, 30 can be provided with suitable inlet bevels, so that it is ensured that the projections 23, 30 on the mutually assigned surfaces (regardless of the position in the longitudinal direction of these components with respect to one another) can be interlocked and thus engage behind one another. In this way it is ensured that the coupling shaft 21 does not have to overcome the distance a before it mechanically engages the actuating component 5. This avoids an empty path of the order of the distance a.
- the coupling shaft 21 is either in the power flow with the transmission member 26, or in the fallback level with the actuating component 5.
- the coupling shaft 21 is rotated by a reset mechanism so that the projections 23, 30 between the actuating component 5 and clutch shaft 21 are engaged.
- the brake pedal force is thus passed directly in the direction of the booster 6 or the master brake cylinder 11.
- the projections 33, 34 between the coupling shaft 21 and the transmission member 26 are no longer in engagement and thus the coupling shaft 21 can slide through the transmission member 26.
- the design ensures that no brake pedal travel is lost when the brake pedal 1 is already depressed and the braking effect or the pressure in the brake lines is thus maintained when the brake pedal 1 is entered. If the brake pedal 1 is depressed in normal operation, this is sensed by a driver's request detection and the downstream amplifier 6 is activated. As a result, the actuating component 5 is pulled away from the clutch shaft 21, so that these two shafts do not normally touch. The same applies when releasing the brake. The clutch shaft 21 is moved into the starting position quickly enough so that contact between the clutch shaft 21 and the actuating component 5 is avoided.
- FIG. 5 A solution for the electromotive actuation of a master brake cylinder 11 by means of a ball screw 43 is shown in FIG. 5.
- a movement of a by-wire brake pedal 1 is detected by sensors 3 and the signal is fed to a control unit (not shown). Because the brake pedal 1 is mechanically decoupled (distance a), the driver only feels feedback forces which are generated as a result of a simulator 2.
- the control unit 4 energizes an electric motor 44, which leads to a rotor rotational movement, the movement of which is converted by means of the ball screw drive 43 into an axially directed displacement movement of a tubular sleeve 45, so that in this way a hydraulic piston 46 (as a downstream actuating component) of the master brake cylinder 11 is operated.
- At least one actuating component 47 is articulated on the brake pedal 1, which is arranged displaceably within the tubular sleeve 45, and the end of which in the unactuated state and in the by-wire mode is at a distance a from the downstream actuating component 46 (hydraulic piston), which is the Decoupling causes. In the fallback level, the distance a is overcome and direct direct actuation takes place via the brake pedal 1 and the two actuating components 37, 47.
- FIGS. 6 and 7 have a coupling 48, which in principle coincides with one another, for reducing the free travel a in the fallback level.
- this coupling 48 is shown in FIG. 6 in connection with a vacuum brake booster 6, different booster concepts, such as in particular hydraulic boosters, can be used as already described.
- the coupling 48 is provided between the two actuating components 37, 47 and has a block-shaped body 40 which can be positively inserted into the distance a in such a way that the free travel a is bridged positively.
- the arrangement is comparable to a door latch, and the body 40 is automatically pushed between the two actuating components 37, 47 in the fallback level due to the lack of current supply to a restraining device in order to reduce free travel.
- an elastically prestressed spring 41 is provided as the drive, which urges the body 40 into the intermediate space.
- the function of the device according to FIG. 7 is the same with the exception of the amplifier.
- the hydraulic amplifier illustrated by way of example in FIG. 7 comprises a motor-driven pump 53 which draws in from the container 12 and feeds a high-pressure accumulator 54.
- the high-pressure accumulator 54 can fill a pressure chamber 55.
- the pressure is controlled by means of a normally closed solenoid valve (SG) and a normally open solenoid valve (SO) in a tank branch. Volume can only be drained from the high-pressure accumulator 54 into the pressure chamber 55 by opening the SG valve become.
- a pressure sensor DS 1 and DS 2 is arranged upstream of the SG valve and after the SG valve, with DS 1 enabling storage level monitoring for pump activation and DS2 for pressure control in the brake circuits.
- FIG. 8 illustrates a by-wire brake actuation system with an electronically actuated, pneumatic
- Brake booster 6 in connection with two electromechanical wheel brakes 49 which can be controlled electromechanically via a separate electronic unit (50, ECU) and for two wheel brakes 16 which can be controlled electro-hydraulically for a front axle.
- the hydraulic wheel brakes 16 of the front axle are fed via a distribution device (hydraulic unit, HCU; 10)), which in turn is controlled by an electronics unit 4 (ECU).
- This ECU is supplied with signals from a (diaphragm) eg sensor 17 and a pressure sensor 18 which is arranged in the brake circuit of the front wheel brakes 16.
- the ECU 4 receives the signals from two displacement or rotation sensors 3, 51 which are assigned to the brake pedal 1 and a simulator (force feedback pedal) 2 for generating reaction forces.
- a brake light switch 52 also feeds its signal into the ECU 4.
- the ECU 4 together with the booster 6 and the distribution device 10, supplies the hydraulic wheel brakes 16 with the required hydraulic pressure and also enables driver-independent control of the brake booster 6 and control of the simulator 2. LIST OF REFERENCE NUMBERS
