Description

The Invention relates to a method for controlling a transmission, in particular an automatic transmission, a motor vehicle according to the preamble of claim 1 closer defined type.

From the DE 39 22 051 A1 a method for controlling an automatic transmission is known, in which a driving activity evaluation is performed in order to be able to adapt shift programs or shift characteristics for the gear change to control gearshifts of the transmission to the respective driver style of the driver. The adjustment is made by determining the driver's driving style by detecting and evaluating throttle position, vehicle speed, lateral acceleration, longitudinal acceleration, longitudinal deceleration, engine speed, throttle change rate, throttle position, and throttle speed. On the basis of these data, a driving activity or a driver type is determined by means of a filtering. On the basis of the ascertained driving style or driving type, a corresponding selection of the shift strategy is made with adapted shift characteristics and / or clutch characteristics.

Instead of the throttle position can be at a direct connection between Accelerator pedal and throttle also also an accelerator pedal signal instead the throttle are used. For example, at high Values of the pedal speed, the pedal gradient, the frequency of the pedal operation and / or the pedal position a performance-oriented, sportier Driving style determined and it is a corresponding performance-oriented adapted sporty driving strategy. This can cause, for example the gearshift and / or clutch characteristics are changed to higher engine speeds, for a sporty driving at higher engine speed and higher torque cause.

at low values for the pedal speed, the pedal gradient, the frequency the pedal operation and / or the pedal position, an economical driving style is determined and adapted a correspondingly fuel-efficient driving strategy. This can cause, for example, the gear shift and / or the Clutch characteristics are changed to lower engine speeds, a fuel-efficient driving at lower engine speed to effect.

Between These two driving styles can also in this regard Intermediate values are determined to be a corresponding adjusted Adaptation between the performance-oriented and the consumption-optimized Strategy.

Indeed can despite this adaptation of the driving strategy to the driving style of the Driver's matching gearshift and / or clutch actuation operations done. For example, an upshift can take place just before a curve pass, because the shift characteristic requires this in the given driving situation, although this is rather undesirable in such driving situations, because before the corner entry usually a deceleration takes place and thus an upshift due to the associated acceleration the vehicle would be inappropriate. Also, it may be in a downhill drive in overrun due to the Switching characteristics and the driving situation of the vehicle come upshifts, although a failed shift or possibly even a downshift would be more appropriate to make better use of the engine braking function.

task The invention therefore relates to a method for controlling a transmission. in particular an automatic transmission to provide a motor vehicle, by means of the one to the respective driving situation and the respective Driver better adapted and more immediate gear shift and / or clutch Control is feasible.

B. when driving uphill by pressing a selector lever in an alley for manual switching, depending on the timing of the inference be done and stored on a specific driver's habit. On This way, for example, in favor of spontaneity or sportiness the vehicle an adapted shift strategy to a gear sound and / or Clutch actuation process with, for example, earlier Information for coupling preparation can be selected.

Of Furthermore, with the method according to the invention and here intended identification of a driving situation pattern are detected, if z. B. regularly the same driving distance covered is, with which also circuits especially for this driving situation pattern can be adjusted. In the driving situations can not only the current situations such. B. longitudinal and lateral accelerations but also forward-looking information about the present road course be processed for example by means of a navigation system.

In order to the gearshift behavior of the gearbox can not only be based on the in a driver behavior pattern stored driver habits z. By delay times, Offsets and factors changed but also typical features of an already driven several times Take into account the route.

The alley can become manual Circuit of the transmission to be an alley in which when moving of the selector lever a circuit in a higher or lower gear is controllable. This can be done by that a short actuation path in a tip position is driven through, depending on the direction of the movement driven up or downshift can be. Also can instead of a selector lever other, for example, arranged on the steering wheel selector elements be usable.

It may also be advantageous if the at least one functional unit a driving program selection element and generates a data signal when the driving program selection item is operated in a predetermined setting. For example, can when switching to a low-consumption Fahrpro program or winter driving program or sporty driving program a data signal to be generated.

The 1 shows a schematic representation of an automatic transmission 2 for a motor vehicle with an internal combustion engine with an electro-hydraulic control 1 , The automatic transmission 2 may be a stepped automatic transmission with torque converter, a dual-clutch transmission, a continuously variable transmission, also known as CVT transmission, an automated transmission or a similar automated gearbox adjusting or switching transmission. If a gear change or a shift is mentioned below, this also applies to a ratio change of a continuously variable transmission.

The control 1 includes an electronic control unit 3 which signals among others from a kick-down encoder 4 , a throttle switch 5 , a throttle angle sensor 6 , a speed sensor 7 , a transmission output speed sensor 8th , a lateral accelerator supply encoder 14 and a speed sensor 15 receives and processes. The control unit 3 controls a pressure regulator depending on the incoming signals 9 and solenoid valves 10 . 11 . 12 and 13 at. This will automatically control translation changes of the automatic transmission 2 allows, as they also from the DE 39 22 051 A1 is known.

The 2 shows a simplified block diagram illustrating a realizable example of a control program according to the invention method for controlling a transmission. The block diagram shows different blocks 101 . 102 . 103 . 104 . 105 and 106 that communicate with each other via internal program interfaces 106 Exchange data. This is a first block 101 the operating system of the control program. In a second block 102 the driving strategy is calculated and determined on the basis of the vehicle data and data of the operating elements for detecting a driver-side operation and the respective operating situation of the vehicle.

In parallel, within a third block 103 Monitoring and control unit shown performed monitoring that detects whether a driver-side control of an operating element is present or another recognition of a relevant condition exists, such as a previously stored route is present, a slope or slope distance is present, whether cornering is imminent etc These data are stored in a memory, such as preferably in a circulating memory. At the same time, these data are assigned switching signals and these are linked to data records, and a switching behavior is generated, which is recognized upon repetition. Thereby, a driver behavior pattern or a driving situation pattern with respect to the travel route can be recognized and the shift strategy adapted thereto.

In a fourth block 104 the shift sequence of the transmission is controlled. For this purpose, in an electro-hydraulic transmission control, the pressure of the hydraulic medium and the respective valves are actuated to actuate a switching element or a plurality of switching elements such as clutches or brakes to achieve a gear change. In this block 104 Also, the timing of the gear change and the respective operation of the switching elements is controlled. For example, a shift of the Ge gear ratio in a more sporty or performance-oriented driving program faster and at higher torque than in a more comfort-oriented or consumption-oriented driving program.

In a fifth block 105 a diagnosis is carried out whereby a plausibility check of the data and signals is carried out and if necessary replacement programs are activated.

Overall, the transmission control communicates with other electronic units of the vehicle by means of a data bus 106 , such as the CAN bus.

The 3 shows in a block diagram in principle a closer embodiment of the driving strategy determination and the evaluation and control unit according to the blocks 102 and 103 in 2 ,

In a block 201 For example, a driver type rating is made based on various input data provided with blocks 202 to 207 are symbolized, wherein the data connection is indicated in each case by an arrow.

This is done in a block 202 carried out a Abfahrerkennung, that is, in the state "starting" due to vehicle data, such as throttle position, accelerator pedal position and / or engine torque during the starting process, it is detected which driving style or driver type is present. In this block, each startup procedure is evaluated based on the maximum engine torque during the startup process. If you start from a standstill at higher engine torque or at full throttle, a more sporty, optimized power shift program is immediately assigned.

In another block 203 it is determined whether there is a quick power demand of the driver. This can be determined by registering very fast accelerator pedal movements with a high gradient of the accelerator pedal movement. In such a case, a momentary increase in a degree of a driver type may occur. Thus, with very fast pedal movement from a partial load position to a full throttle position, a counter can be raised to the highest level for sportiness and a downshift can be activated. This increase of the Sportlichkeitszählers is expediently only temporarily for a certain period of time. Subsequently, the counter is reset to its initial value. In such a situation, an upshift can again be triggered together with a return of the gas.

Furthermore, in a block 204 an engine torque is determined, and in a block 205 determines or monitors a kick-down position. The kick-down position is an over-throttle position of the accelerator pedal which requests the maximum engine power. If the driver stays longer on the kick-down position, the sportiness counter is cyclically increased in the present case. After leaving the kick-down positi on the increase of the Sportlichkeitszählers is withdrawn after a predetermined time again.

In another block 206 becomes the longitudinal acceleration of the vehicle and in yet another block 207 determines the lateral acceleration of the vehicle.

Out of the blocks 202 to 207 represented data is in block 201 the driver type evaluation performed. The result of this evaluation is in a block 220 processed for driving program selection.

In the block 220 for driving program selection, the data of other blocks 208 to 214 and 231 processed. It is in a block 208 carried out a city detection. Due to the vehicle data, such as speed and / or accelerator pedal position and possibly their temporal changes can be concluded on a city trip, If a city trip detected, a corresponding signal to the block 220 forwarded to the driving program selection.

In a block 209 there is a driving resistance detection, which advantageously begins already when driving off and constantly runs in the background. The result is a road resistance metric that is a measure of a level, downhill or uphill ride, and also to the block 220 for driving program selection is forwarded. The driving resistance is determined by an equilibrium observation, wherein the driving force, corresponding to the engine torque, is in equilibrium with the driving resistances, such as rolling resistance of the tires, vehicle weight and its inertia, air resistance and gradient resistance. Based on this data, the slope resistance can be determined and closed on the downhill or uphill. According to the determined slope or the gradient, the driving programs are adapted, so that no manual intervention is necessary to effect a downshifting of the transmission to realize a larger engine torque. The downshift occurs at lower speeds than in the plane. Also, the load of the vehicle can be determined by this function to adjust the driving programs accordingly.

Further input variables for driving program selection are provided by a block 210 symbolized low-frust recognition, one by block 211 symbolized cruise control, one with block 212 designated determination of a warm-up phase of the engine, one in block 213 carried out detection of a high-temperature state of the engine and one in block 214 provided determination of an anti-slip control mode. The data of the block 214 be both the block 220 for driving program selection as well as a block 250 provided for gear selection.

With a block 230 is called a manual transmission control, with the program button 23i , a selector lever 232 and a tip operation 233 manually influence the transmission control can be taken. The data of the program button 231 are thereby to the driving program selection 220 forwarded.

The data of the blocks 208 to 214 and 231 be in block 220 processed to make a driving program selection. The result of the driving program selection is sent to the block 250 forwarded to the gear selection.

In block 250 for gear selection, the data of the block will continue 232 , in which the setting of the selector lever is detected, of the block 233 in which it is determined whether the selector lever is in a jog position, by means of which manual upshifts or downshifts can be requested, a block 234 for fast-off detection, in which a rapid return of the accelerator pedal is detected, a block 235 for curve recognition and a block 236 , in which a spontaneous deceleration of the vehicle is detected, processed.

In block 250 Based on this data, a gear selection will be made, which is indicated by arrow 251 is triggered and is controlled by actuators of the transmission.

The block 250 also gives switching signals to the evaluation and control unit 103 for driver behavior observation or driver habituation surveying. In this evaluation and control unit 103 are also data from blocks 241 to 243 processed. The block 241 stands representative of elements that can be activated by the driver, such as the bunker, the audio system keyboard, the selector lever, the driving program selection elements, seat adjustment elements etc. Block 242 is representative of electronic units that can automatically provide information about driver habits or driver behavior, such as a Global Positioning System (GPS) unit or navigation system. This can determine the current route, so that habitually driven routes can be detected and stored. Also, an audio system can recognize a genre of music or a tuned radio station. If these settings are habitually repeated several times, they can be saved and recognized. block 243 stands for other direct driver identification systems, such as key recognition, code recognition or the like.

The data of the blocks 241 to 243 are stored in a memory, such as preferably circulation memory. This circulating memory permanently stores the incoming data. The circulation memory is connected to the evaluation and control unit 103 connected to the data of the blocks 241 to 243 with switching signals from block 250 linked and used to generate a switching behavior as a data record, which in case of repetition z. B. is detected as a driver behavior pattern.

If such a pattern of behavior is detected, a re-occurrence of the data signals, a preparation for a possibly upcoming switching signal assuming the switching behavior, so that the initiation of the switching process can be done faster compared to an initiation of the switching operation in the sole presence of the switching signal. The evaluation and control unit 103 generates for this purpose a so-called pre- or pre-switching signal, which leads to the fact that, for example, clutches are pre-filled or switching operations are suppressed, depending on the driving situation, route situation and / or driver behavior.

The 4a shows a diagram in which a Zughochschalqtung an engine speed n_mot, an acceleration a, a pressure p_k_ab for a clutch off and a pressure p_k_zu for a clutch to be activated as a function of time t are shown.

The 4b schematically shows a gear assembly for gear change between two gear ratios. In the event that a translation is switched ix, the disconnecting clutch k is closed off and the engaging clutch k_zu open. The transmission output speed n_ab is then equal to n_an * ix. To switch the ratio in a stage iy the disconnecting clutch k is opened off and the switching clutch k switched on. The transmission output speed n_ab is then equal to n_an * iy.

In 4a According to the prior art, a switching command S is output at a time t = t ₀ . At a late time t ₁ then takes place the essential noticeable reaction R of the transmission, to which the disconnecting clutch k_ab is emptied and the switching clutch k is to be filled. The noticeable reaction thus takes place only at t = t ₁

In the case of the method according to the invention with driver's custom recognition, an advance notice is perceived at t = t ₀ , whereupon a pre-switching signal V is generated and the clutches can be prepared for changing gears, such as eg. B. can be prefilled. If a switching command S 'then follows at t = t ₁ , a noticeable reaction R' can be detected immediately after the switching command. The switching command and the noticeable reaction then take place almost at the same time.

By the driver custom recognition will be the transmission control in the Location offset, very early to be prepared for a shift request of the driver and on this directly by operation to be able to react by switching elements.

One example for A driver's action is that a driver that comparatively rare in the manual switching mode (tip mode), immediately switches a circuit wishes. This is recognized because during the transition in the manual tip position immediately the driver's command for the circuit ((+) - position or (-) - position of the selector lever) he follows.

One another example of a driver action is in conjunction with a global positioning system or a navigation system that a driver when driving the always same distance at certain points of the route, z. B. in curves, always the same circuit, such. B. a downshift, manually selects.

Another example is when the driver changes at each descent into the manual shift gate and then switches back manually by means of a tip circuit. Also, he can select the limiting function of the transmission, in which the automatic gear selection is limited to a maximum gear. If the currently engaged gear is above this limit, a downshift takes place. Has the evaluation and control unit 103 One or more times this habit is recognized, so it is possible to prepare the appropriate clutches on an upcoming circuit on the next downhill and a change in the manual lane or before a change in the limit position. Example is that the driver changes to the manual shift gate and according to the established habit in probably a short time, such as in 3.2 seconds, switches back. For example, he calls for a downshift from 6th gear to 5th gear.

Another example is when the driver changes into the manual selection lane before each overtaking maneuver and manually switches back or uses the limit positions. Has the evaluation and control unit 103 once or several times recognized this habit, it is possible to prepare for the upcoming overtaking and a change in the manual shift gate or before a change in limiting position, the appropriate clutches on an upcoming circuit. For example, the overtaking is detected by the fact that the driver goes from the accelerator pedal, the turn signal is actuated and the steering angle sensor detects a steering angle excursion. In such situations can be the evaluation and control unit 103 stored memory data that make it likely that the driver within a typical period of time the selector lever from position D back to position 4 changed and thus in a 6-speed gearbox requests a 6-4 downshift.

According to one another embodiment of the invention actuated the driver the turn signal by means of the Blinkerbetätigungselementes a certain Time before each turn or before each overtaking. If the custom memory has a or several times this behavior is detected and stored, so is it is possible before the next overtaking or before the next Turn off when setting the turn signal by the corresponding actuator to prevent an upshift of the current transmission ratio.

In a further embodiment of the invention, the driver drives multiple times or even regularly the same route from A to B. Has the evaluation and control unit 103 one or more times recognized this recurrent route profile, so it is possible to pendulum circuits such. As upshifts before a turn or to avoid imminent uphill or downhill.

According to a further embodiment of the invention, the driver selects on the audio system of the vehicle a specific music CD with a specific music direction or a specific radio station. Has the evaluation and control unit 103 one or more times z. B. the change from classical music to rock music or pop music or vice versa recognized, it is possible to prepare a possibly sportier or more consumption-oriented driving style, depending on the nature of the change in the genre or the station. So z. B. in a change from a heavy metal music direction to pop music direction, a calmer driving program and a less sporty shift sequence be selectable.

These Behavioral patterns can by means of the procedure according to the invention be recognized and lead to a pre- or pre-switching signal, the to a subsequent Preparing the switching or coupling operations leads, so that at the next driver side Switching command the circuit can be made directly. For the If the driver-side switching command then fails, the Preparation withdrawn after a predetermined period of time become.

Also it can cause that certain automatic gear changes are omitted, if a corresponding driving situation is detected, such as a downhill run, Uphill or an upcoming cornering.

The 5 shows a schematic representation of a storage unit according to the invention 501 with the evaluation and control unit 103 , The storage unit 501 receives data signals 502 from the functional units representing an actuation or a condition. The control and evaluation unit 103 determines or receives switching signals 505 to the gearshift and / or clutch actuation process, wherein the control and evaluation unit 103 the data signals 502 the at least one functional unit with the switching signals 505 linked and as a record 506 stores. If the currently detected and linked data signals and switching signals match a stored data record, the record is stored as a z. B. driver behavior patterns identified and stored. When the data signals of such a data set reappear, the evaluation and control unit recognizes 103 a possible reoccurring habitual behavior and causes an adaptation of the shift strategy for gearshift and / or clutch actuation process by a so-called pre or pre-switching signal 504 is generated, after which a preparation of a switching operation takes place or a switching operation would take place which would not be carried out.
