Definitions
- the present invention relates to a method for recognizing the synchronous position and the end of the synchronization process of an automatic transmission according to the preamble of claim 1.
- Manual transmissions for motor vehicles have already become known in many embodiments.
- a manual transmission has mainly been understood to mean a manual transmission in which the driver of a motor vehicle equipped with such a transmission carries out the process of selecting the shift gate and performing the switching process manually via the shift lever.
- automated manual transmissions have also become known in the meantime, in which the process of selecting and shifting the selected gear stage takes place, for example, under program control via actuators provided on the manual transmission.
- Such an automated manual transmission is subject to normal wear of its components in the form of, for example, synchronization during its operation, which can lead to a shift in the middle synchronous position.
- the middle synchronous position is to be understood as an average position value during the synchronization process, since the position at which the synchronization locks can change somewhat from switching process to switching process, because the switching sleeve cannot intervene in a predictable way from switching process to switching process.
- the detection of the load current is comparatively complex and expensive and, moreover, can only lead to results relating to the detection of a change in the synchronous position as part of ongoing position detection of the actuator, since the position of the actuator must be known when the load current increases.
- the present invention has for its object to provide a method with which a change in the synchronous position and the end of the synchronization process can be detected in a less complex manner.
- a method for recognizing the synchronous position and the end of the synchronizing process of an automated manual transmission with an electromotive shift actuator is provided, according to which the speed of the shift actuator is detected and the synchronous position and the end of the synchronizing process is determined on the basis of the change in the speed ,
- the path of the switching actuator which is referenced to the time, allows the path covered by the switching actuator to be determined without further ado, so that the synchronous position can be determined even without the position of the switching actuator being continuously detected, which is then achieved when the speed of the switch - a predetermined threshold value changes in a predetermined period of time experience.
- the speed can be detected by means of sensors which generate a predetermined number of pulses per revolution of the actuator shaft.
- the speed is determined by measuring the pulse frequency and / or the temporal pulse interval. It is also possible to determine geometric distances by adding the pulses.
- the synchronization exerts a blocking effect against further movement of the switching actuator, which is unlocked after the end of the synchronization process and thus leads to an increase in the speed of the switching actuator.
- the synchronous position and the end of the synchronization process is determined independently for each gear stage of the automated manual transmission.
- the method according to the invention can therefore be used to detect gear-specific changes in the synchronous position and also to determine a gear-specific end of the synchronization process.
- Changes in the synchronous position of the respective gear stages of the automated gearbox during operation can therefore be taken into account in that the synchronous position is detected and this synchronous position is used as the presumed target synchronous position in the next gear change process in the respective gear stage for the actuation of the shift actuator.
- the speed of the switch actuator determines whether the synchronization process is complete, which can be determined, for example, by a parabolic or generally progressive increase in the speed of the switch actuator over time.
- the load current for the shift actuator can be increased accordingly without further delay, so that the end position of the shift actuator can be reached quickly on its way to bring about the gear stage to be engaged, which leads to a shortening of the travel time of the Switch actuator to reach the end position and thus reduce the switching time.
- the determined synchronous position is stored in a memory device and that it is read out from the memory device as the target synchronous position for the approach of the synchronous position by the shift actuator during the next gear change process.
- a volatile memory can be provided, in which the synchronous position is written when the manual transmission is in operation.
- these values can be adjusted according to Parking the vehicle, for example controlled by an ignition signal, can be written into a non-volatile memory from which they can be read out again the next time the vehicle is started up and written to the volatile memory.
- the stored synchronous position is updated by the synchronous position determined by the method if the stored synchronous position deviates from the determined synchronous position, so that changes in the synchronous position do not lead to a change in the shift characteristics of the transmission.
- the update is carried out when the determined synchronous position changes in different directions compared to the stored synchronous position for individual gear stages of the automated manual transmission in relation to the neutral position.
- the update is carried out only when the manual transmission is at operating temperature, a sensor being provided on the manual transmission to determine the temperature and / or a predetermined operating time of the manual transmission is awaited.
- a sensor being provided on the manual transmission to determine the temperature and / or a predetermined operating time of the manual transmission is awaited.
- the stored synchronous position is used to control the shift actuator in such a way that it reduces the speed of the movement of the shifting elements in the manual transmission before the target synchronous position. A high mechanical load on the switching actuator and the switching elements is thus avoided.
- the change in the synchronous position is determined in relation to the neutral position and an action message is output when a predetermined change threshold value is exceeded.
- a predetermined change threshold value can be a corresponding entry in the fault memory of the vehicle, for example, so that suitable remedial measures can be taken the next time the vehicle is in the workshop, for example worn synchronizer rings in the transmission can be replaced.
- Figure 1 is a graphical representation of the position of the shift actuator when engaging a gear while the transmission is synchronized.
- Fig. 2 is a diagram for explaining the identification of shifts in the synchronous position
- Fig. 3 is an illustration for explaining a shift of the circuit diagram
- Fig. 4 is an illustration for explaining the meaning of the synchronous position.
- the curves 1 and 2 each denote the switching process when a "neutral" synchronous position is present, while the curves 3 and 4 do this for a "neutral" synchronous position.
- neutral distant is a change in the one determined by the control
- the switching actuator is first applied linearly over time and then braked to the synchronous position or synchronization, which opposes a further movement of the method during the synchronization process. This means that the switch actuator is braked and almost comes to a standstill until time A, but it still remains one
- the curves 3 and 4 with reference to FIG. 1 show similar relationships with a synchronous position closer to the neutral position.
- a change in the position of the shift actuator expressed in curve 3 and thus a shortening of the shift time can be achieved even in a synchronized position closer to the neutral position.
- the Curve line 4 in comparison shows, for the sake of clarity, an end of the synchronization process assumed too early with a corresponding extension of the time until the switch actuator reaches the end position, ie the "gear engaged" position.
- the actual synchronous position (ST) is further from neutral than the synchronous position (SV) used or assumed by the control. This is concluded from the fact that the standstill position (SS) was determined above the synchronous position SV used.
- This standstill position (SS) is also shown in FIG. 1 of the drawing and corresponds to the position of the shift actuator after braking (horizontal curve course) and is established during the synchronization process.
- a large acceleration (A>) can be determined, which corresponds to the steep position parabola in FIG. 1, so that an adaptation, i.e. Correction of the assumed synchronous position (SV) used by the control is useful.
- This synchronous position determined in this way can then be written to the control system memory as a new synchronous position.
- Case 2 shows that the actual synchronous position (ST) is closer to neutral than the assumed synchronous position (SV). There is a low acceleration (A ⁇ ). The assumed synchronous position (SV) was assumed above the standstill position (SS) and the actual synchronous position (ST), the actuator still worked against the locking effect of the synchronization. It makes sense to adapt towards neutral.
- Fig. 3 of the drawing shows an illustration for explaining a shift of the Diagram. In relation to the neutral position, there is one in each forward gear
- Fig. 4 of the drawing finally serves to explain the meaning of the synchronous position.
- the control uses the assumed synchronous position SV to brake the shift actuator before the standstill position SS is reached. This serves to reach the standstill position as quickly as possible in order to shorten the time for the gear change process, but without “driving" into the synchronous position at high speed of the shift actuator, since this causes a "rebounding" due to the locking effect of the synchronization. of the switch actuator would lead.
- the switching actuator must absorb the forces arising from direct contact with the synchronization, which leads to the rebound described above. If the synchronous position SV is assumed to be close to neutral, the switching actuator is braked too early. This then “creeps" slowly to the standstill position SS. The time of the interruption of the tractive force during the gear change process increases, which has a negative impact on shifting comfort. If the synchro position SV is correctly assumed (due to an adaptation during the previous shift process), the high mechanical load on the shift actuator is eliminated and on the other hand results there is a short time for the gear change process and thus a short interruption in tractive power.
