Definitions
- Multi-channel pressure control module with only one pressure sensor
- the invention is based on an electro-pneumatic pressure control module for a pressure-medium-operated brake system of a vehicle with at least two channels, which is pneumatically controlled in undisturbed operation and pneumatically in a fault in the electrical system, according to the preamble of claim 1 and a method for operating the Electro-pneumatic pressure control module according to the preamble of claim 6.
- Such a pressure control module is known for example from DE 40 30 980 A1.
- the well-known 2-channel pressure control module each has a channel for a brake actuator of a right wheel and a brake actuator for a left wheel of an axle and includes per channel a relay valve controlling electro-pneumatic valve unit, each of which an inlet valve and an exhaust valve and a backup Valve has.
- an electric brake request signal is controlled in a control unit depending on a driver request, which control commands for the
- the Fors. Exhaust valve controls to a control chamber of the associated relay valve to vent or vent.
- a pressure sensor communicating with the control chamber of the relay valve thereby measures the working pressure generated in a working chamber of the relay valve and reports a corresponding signal to the control unit in order to realize pressure regulation for the respective channel.
- the backup valves are in the blocking position, ie, a pneumatic braking request signal generated in parallel with the electrical braking request signal is not controlled through to the control chambers of the relay valves.
- the pneu- matic and the electrical braking request signal are generated by a breadth module.
- the controller In case of failure of the power supply or a fault in the electrical system, the controller is de-energized and the backup valves switch spring loaded in their passage position, so that the pneumatic brake request signal switches as control pressure to the control chambers of the relay valves, which then produce an unregulated working pressure as a brake pressure in their working chambers ,
- the working chambers of the relay valves are each connected to a pressure sensor, so that each channel own pressure sensor is available and a separate control of the two channels of the pressure control module is realized.
- a pressure control module is relatively complex.
- the present invention is based on the object to further develop a pressure control module of the type mentioned above in such a way that it is simpler in construction and less expensive to manufacture.
- an electro-pneumatic pressure control module for a pressure-medium-operated brake system of a vehicle with at least two channels, which is controlled electrically in undisturbed operation and pneumatically in the event of a fault in the electrical system
- one of an electronic control unit controllable electro-pneumatic valve unit with at least one backup valve, an inlet valve and an exhaust valve and at least one relay valve with a Control chamber and a working chamber is provided and the electro-pneumatic valve unit controls the relay valve pneumatically
- the backup valve in case of a failure in the electrical system with a device for generating a driver's desired control pressure and on the other hand with the control chamber of the relevant channel associated relay valve is connectable
- the working chamber of the relay valve of a channel with at least one pneumatic brake actuator associated with at least one wheel and the working chamber of the relay valve of another channel communicates with at least one other pneumatic brake actuator associated with at least one other wheel
- at least one between the Control chamber of the relay valve of a channel and the control chamber of the relay valve of the other channel extending pressure medium connection is provided, in the pressure medium connection, the backup valve of a channel is arranged, little at least one wheel speed sensor associated with the one wheel and at least one wheel speed sensor associated with the other wheel is provided, each wheel speed
- the backup valve of a channel which is switched in the prior art only in disturbed operation in the forward position, switched even in undisturbed operation in forward position to achieve a channel-wise separate pressure in the working chambers of the relay valves of the channels, for example to realize a channel-by-channel separate slip control or slip control for each channel, although there is only a single pressure sensor for multiple channels.
- the two backup valves are not connected as in DE 40 30 980 A1 parallel in the leading from the foot brake module control pressure line, but serially, i. the backup valve of one channel can control the driver pressure-dependent control pressure generated by the foot brake module only in the control chamber of the relay valve assigned to one channel, even if the backup valve assigned to the other channel is switched to the forward position.
- This connection can be made in a simple manner by providing corresponding channel bores in the valve block receiving the valves.
- the method for operating the electro-pneumatic pressure control module provides that, starting from an at least three-dimensional characteristic map stored in the control unit, in which the dependency of an opening duration of the inlet valve and / or an opening duration of the outlet valve on a desired working pressure and on an actual working pressure is stored is
- the backup valve of the one channel is switched by the controller in the forward position to connect the control chamber of the relay valve of one channel with the control chamber of the relay valve of the other channel the actual working pressure in the working chamber of the relay valve of one channel or in the working chamber of the relay valve of the other channel is measured by means of the single pressure sensor and a corresponding actual working pressure signal is reported to the synchronous pressure control unit in all channels,
- the actual working pressure in the one communicating with the pressure sensor a working chamber of the relay valve of a channel or in the other working chamber of the pressure sensor connected to the Relay valve of the other channel and an actual operating pressure signal for the one channel or for the other channel is reported to the control unit to produce a working pressure for one brake actuator or the other brake actuator in the context of pressure control of one channel or the other channel .
- the opening duration of the intake valve and / or the opening duration of the exhaust valve of the electro-pneumatic valve unit of the other channel or Opening duration of the inlet valve and / or the opening duration of the exhaust valve of the electro-pneumatic valve unit of a channel is determined and the inlet valve or the outlet valve for the determined opening duration is opened to in the working chamber of the relay valve of the other channel or in the working chamber of the relay valve of the one channel to generate a working pressure for the other brake actuator or for the one brake actuator as part of a pressure control of the other channel or the one channel.
- the characteristic field in which the dependence of an opening duration of the inlet valve and / or an opening duration of the outlet valve on a desired working pressure and on an actual working pressure is stored is preferably programmed end-of-line and reflects the existing laws based on the structural boundary conditions whereby, for example, an opening pulse of a certain duration of the inlet valve generates a certain control pressure in the control chamber of the associated relay valve, whereupon the relay valve controls a certain actual working pressure which can be measured. Since the opening pulse, with which the inlet valve has been acted upon by the control unit, corresponds to a specific brake request signal and therefore also to a certain desired working pressure, a relation between the Duration of the opening pulse, given the expected actual working pressure and the desired working pressure, which is shown in the map.
- an expected actual working pressure can be determined on the basis of the characteristic map depending on the braking request (desired working pressure) and on the duration of the switching operations of the intake and exhaust valves, without the need for a pressure sensor for measuring this actual working pressure would be necessary.
- the opening duration of the intake valve and / or the opening duration of the exhaust valve the other channel are determined, which is cut off at different wheel rotational behavior of the pressure sensor. This opening duration determined by means of the characteristic map then determines the actual actual working pressure in the working chamber of the relay valve of the other channel, if a different wheel rotational behavior is present and no more synchronous regulation of the channels takes place.
- the value for the desired working pressure is thereby preferably generated by an ABS (anti-lock braking system), ESP (electronic stability program), ASR (traction control) or ACC (Adaptive Cruise Control) system and / or depending on the driver, i. the desired working pressure comes directly from a service brake value transmitter such as the pneumatic channel of a foot brake module.
- ABS anti-lock braking system
- ESP electronic stability program
- ASR traction control
- ACC Adaptive Cruise Control
- the working chamber of the relay valve of one channel with the working chamber of the relay valve of the other channel by means of at least one throttle in flow communication.
- pressure equalization takes place between the two working chambers, which at the same wheel rotational behavior on the left and on the right also causes an advantageous braking action on the right and left.
- pressure differences can be compensated for by tolerance or density-related different geometries of the relay valves.
- a pressure equalization through the throttle is known to be only gradually, so that the slow pressure equalization, for example, a little influenced in the context of a brief ABS operation with different Radcard pressure difference in the working chambers of the relay valves of different channels.
- the wheel rotational speed sensors detecting the wheel rotational behavior of the different channels are comprised of an ABS, ASR, ESP or ACC system, so that the signals of these already existing wheel speed sensors can also be used for pressure control in the channel without a separate pressure sensor, without that additional components are necessary for this.
- EBS electronic braking system
- the pressure control module 1 comprises, for example, two channels, a channel 3a for the brake actuator of the right wheel of the rear axle and another channel 3b for the brake actuator of the left wheel.
- the pressure control module 1 is thus controlled electrically in a known manner in undisturbed operation and in the event of a fault in the electrical system, for example in the event of a power failure.
- the pressure control module 1 has a valve block 2 and one channel per controllable by an electronic control unit 4 electro-pneumatic valve unit 6a, 6b each with a backup valve 8a, 8b, one inlet valve 10a, 10b and one outlet valve 12a, 12b and at least each a relay valve 14a, 14b having a control chamber 16a, 16b and a working chamber 18a, 18b, the electro-pneumatic valve unit 6a, 6b respectively pneumatically controlling the associated relay valve 14a, 14b.
- the backup valves 8a, 8b, the inlet valves 10a, 10b and the outlet valves 12a, 12b are preferably 2/2-way solenoid valves, wherein the inlet and outlet valves 10a, 10b, 12a, 1 2b in the de-energized basic position spring-loaded in locking position and energized in passage position switch and the backup valves 8a, 8b in the de-energized basic position spring-loaded in passage position and energized switch to blocking position.
- These electromagnetic valves 8a, 8b, 10a, 10b, 12a, 12b, 16a, 16b are controlled by the electronic control unit 4.
- a control pressure line 18 leads to a connection 20b of the backup valve 8b assigned to the other channel 3b.
- this backup valve 8b is de-energized and therefore switched to the forward position, as a result of which the control pressure supplied by the foot brake module is switched to its other connection 22b, which is in communication with a compressed air duct 24 formed in the valve block 2.
- control chambers 16a, 16b of the relay valves 14a, 14b of the one channel 3a and the other channel 3b are connected to this compressed air channel 24.

- the backup valve 8b of the other channel 3b is preceded by the compressed air passage 24 and the backup valve 8a of one passage 3a such that the compressed air passage 24 and the backup valve 8a of one passage 3a only by means of the backup valve 8b of the other Channels 3b can be supplied with the driver's request dependent control pressure. Due to the backup valves 8a, 8b, the control chambers 16a, 16b of the relay valves 14a, 14b are therefore initially connectable to the foot brake module and thus to the control pressure generated there.
- the inlet valves 10a, 10b are respectively connected to a compressed air reservoir 30 of the rear axle, on the other hand they open with their other ports into the control chambers 16a, 16b of the associated relay valves 14a, 14b.

- the control unit 4 a three-dimensional map is further stored, in which the dependence of an opening duration of the intake valves 10a, 10b and / or an opening duration of the exhaust valves 12a, 12b of a desired working pressure and an actual working pressure is stored.
- the pressure control module 1 is associated with only a single pressure sensor 38, which is, for example, in communication with the working chamber 34a of the relay valve 14a of the one channel 3a and thus measures the working pressure prevailing there.
- the working chamber 34a of the relay valve 14a of one channel 3a is in fluid communication with the working chamber 34b of the relay valve 14b of the other channel 3b by means of a throttle 40.
- pressure control mode 1 is then as follows: In undisturbed operation, ie. when the power supply is intact and the control unit 4 is intact, the backup valve 8a of one channel 3a in the compressed air channel 24 between the control chambers 16a, 16b of the relay valves 14a, 14b is dependent on the sensor signals of the wheel speed sensors associated with the right wheel and the left wheel 36a, 36b as described below. The backup valve 8b of the other channel 3b remains closed in undisturbed operation in order to prevent the control pressure formed by the foot brake module from entering the control chambers 16a, 16b of the relay valves 14a, 14b.
- the backup valve 8a of a channel 3a is switched by the control unit 4 in the forward position to the control chamber 16a of the relay valve 14a of the one Channel 3a to connect with the control chamber 16b of the relay valve 14b of the other channel 3b.
- the control pressure is formed in the control chambers 16a, 16b of the relay valves 14a, 14b by switching the intake and exhaust valves 10a, 10b, 12a, 12b, which valves are controlled by the controller 4 as instructed by the brake request signal.
- the backup valve 8a of one channel 3a arranged in the compressed air channel 24 is switched to the blocking position to connect the control chamber 16a of the relay valve 14a of the one channel 3a of FIG the control chamber 16b of the relay valve 14b of the other channel 3b to separate.
- the backup valve 8b of the other channel 3b remains closed.
- the actual working pressure is measured in the pressure sensor 38 in communication with the working chamber 34a of the relay valve 14a of a channel 3a and an actual working pressure signal for the one channel 3a reported to the control unit 4 to a pressure control of the one channel 3a to generate a working pressure for the one brake actuator.

- a slip control device such as ABS, ASR or ESP and the brake request signal of the driver and depending on the value of in the course of even under the same Radcard .
- the intake valve 10b or the exhaust valve 12b of the other passage 3b is then opened for the determined opening period to generate a working pressure for the other brake actuator in the working chamber 34b of the relay valve 14b of the other passage 3b under pressure control.
- the initially end-of-line programmed map is preferably in braking mode in the sense of a "learning" map in synchronous and controlled synchronism of the two channels 3a, 3b (same RadFW ) continuously corrected to adapt to changing conditions.
- the control pressure via the open backup valve 8a of the one channel 3a also enters the control chamber 16a of the relay valve 14a of the one channel 3a.
- a substantially identical working pressure is generated synchronously in the working chambers 34a, 34b of the two relay valves 14a, 14b, which is forwarded to the corresponding brake actuators. Since the control unit 4 is not functional in this case, it does not depend on the pressure sensor 38, so that the working pressure is formed only dependent on the braking request and unregulated.
- the single pressure sensor 38 is not connected to the working chamber 34a of the relay valve 14a of one channel 3a, but to the working chamber 34b of the relay valve 14b of the other channel 3b and measures the actual working pressure prevailing there.
- the backup valve 8a of a channel 3a from the control unit 4 in turn switched to the control chamber 16a of the relay valve 14a of a channel 3a with the Control chamber 16b of the relay valve 14b of the other channel 3b to connect. Furthermore, the actual working pressure is measured in the working chamber 34b of the relay valve 14b of the other channel 3b by means of the single pressure sensor 38 and a corresponding actual working pressure signal to the control unit 4 for a synchronous pressure control in both channels 3a, 3b reported.

- the opening duration of the inlet valve 10a and / or the opening duration of the outlet valve 10 are determined on the basis of the characteristic dsignificant of the value d1 of the working pressure and, depending on the value of the actual working pressure present during the same wheel rotational behavior 12a of the electro-pneumatic valve unit 6a of a channel 3a is detected and the inlet valve 10a or the outlet valve 12a for the determined opening duration is opened to a working pressure in the working chamber 34a of the relay valve 14a of the one channel 3a in the context of pressure control of the one channel 3a to generate the one brake actuator.
- the rotational speed evaluation of the wheel speed sensors 36a, 36b is not effected by the control unit 4 assigned to the pressure control module 1, but, for example, by a central control unit, for example an ABS control unit, which communicates with the control unit 4 of the pressure control module 1 in order to provide it with the wheel speed information to transfer.
