Definitions

  • the invention relates to a transmission device and a method for operating a transmission device according to claims 1 and 24.
  • Transmission devices - especially for the automotive sector - have undergone a major change in the past decades.
  • the transmission devices were originally manual transmissions that were shifted with a selector lever. It was advantageous for the driver that the position and / or inclination of the selector lever provided information about the gear engaged.
  • the selected position of the selector lever - and thus the selected gear or a middle position - was and can be read in many cases, for example, on the top of the gear lever knob as a selector image.
  • the orientation for the aisles was made even easier by guiding the selector lever in a guide that was visible to the driver - a kind of backdrop (eg in an H-shape).
  • the control system automatically opens the clutch, changes the gear and closes the clutch again. That is why there is no clutch pedal in such vehicles.
  • the driver is only connected to the transmission via electrical / electronic signals, which is also referred to as drive-by-wire.
  • the position of the dialing aid can be structured as if there was a direct, geometric connection between the dialing aid and the selected gear, ie a dialing aid for a fifth gear is first pivoted to the right and then upwards
  • the fifth gear of the drive-by-wire does not actually have to be arranged in this position, so that the well-chosen image of the historically grown and intuitively used H-gear (or with 5 or 6 forward gears, an extended H-gear) can be retained without being tied to the gearbox conditions (actual position of the gears).
  • the selection aid is also in a locked position due to its mechanical coupling to the transmission when the gear is engaged. If no gear is engaged, the dialing aid can be moved relatively easily in the dialing lane (apart from a possible reverse gear lock). However, springs acting on the dialing aid cause the dialing aid to spring back into a central position whenever the gear is not engaged.
  • the dialing aid With the drive-by-wire, the dialing aid must only be put into a dialing position for the selection of a specific switching situation. Once the desired switching status has been recognized by the electrical system / electronics, it is no longer necessary to leave the dialing aid in the dialing position. For this reason, in a gear device operated in drive-by-wire, the dialing aid may spring back into a central position immediately after the dialing process. This middle position is also called “stable position". In some cases, automated transmissions also have dialing patterns with several "stable positions". In connection with the description of the figures, this will be discussed in detail here.
  • a drive-by-wire can be unsafe if countermeasures are omitted.
  • at least one transmitter is often attached in the lower area of the dialing aid - for example a selector lever - which activates sensors when the dialing aid approaches a dialing position.
  • a selector lever which activates sensors when the dialing aid approaches a dialing position.
  • Such a sensor is located near a selected position. If a sensor has now been activated, it signals this activation to a controller via a line. By activating the sensor, the controller is informed that a certain selector position has been assumed.
  • the encoder described is often a permanent magnet arranged on the underside of a selector lever.
  • the sensors that respond to a permanent magnet in a reliable form are Hall sensors
  • a controller If a controller is designed accordingly, it can store a signal from a sensor once received until another signal from another sensor arrives. If a control - as described - is not required for a dial position permanently, which is why a springing back of the dialing aid into a “stable position” after “tapping" the desired dial position, but still maintaining the desired gear or comparable.
  • the information about a selected position or a possibly activated Hall sensor is often provided by means of a digital, serial line. Since the CAN bus of a motor vehicle is a serial line, the CAN bus is also often used for the transmission of information from the Hall sensors. In some cases, transmission of the serial information from the selector lever to the control unit is also used via a simple serial protocol. There are two wires on a serial line or a serial data bus. One wire gives the so-called clock signal, while the other line is high or low depending on the clock signal and the information to be transmitted.
  • a gear device - in particular a gear device for motor vehicles - is equipped with a dialing aid, the dialing aid being brought into a desired dialing position when dialing, which according to a dialing pattern, that is to say a pattern of the arrangement of gears, neutral positions, “stable Positions "and driving modes, are arranged.
  • this transmission device has a main position detection for each selector position and a redundancy position detection for at least one single selector position.
  • a sensor system for the main and the redundancy position detection - consisting of a multiplicity of sensors and the associated wiring - supplies the digital signals of both the main position detection and the redundancy position detection.
  • the transmission device is also equipped with a control device which communicates with the main position detection and the redundancy Po via a data bus sition acquisition is connected.
  • a control device which communicates with the main position detection and the redundancy Po via a data bus sition acquisition is connected.
  • the signal of the redundancy position detection is designed as a serial signal.
  • serial signals have the advantage that, in contrast to parallel signals, they only need two signal wires.
  • the clock signal is sent there on a first signal wire, while the actual bit information is sent on the other signal wire.
  • the technical effort - in particular the wiring effort - is considerably higher.
  • eight signal wires alone are required for the transmission of a bit.
  • the signal of the redundancy position detection is transmitted as a serial signal
  • the signal of the main position detection does not necessarily also have to be transmitted as a serial signal.
  • a dialing aid does not necessarily have to be designed as a selector lever within the scope of the invention, as is usually found in the motor vehicle sector.
  • a gear device that is operated in the drive-by-wire does not require a selector lever, as is otherwise required with manual transmissions.
  • a selector lever merely represents a signal generator.
  • a gear in question a neutral position or a driving mode - such as sporty driving behavior - is selected.
  • the selection aid is designed as a selection wheel.
  • the selector wheel can be designed as a rotary knob that has a marking arrow. Depending on the position of the marking arrow on a fixed scale, a gear or equivalent is selected.
  • a dialing aid which is designed as a selector wheel, only allows a sequential selection of the selector positions.
  • sequential selection is to be understood to mean that it is only possible to go from one selection position to the next and that a selection position cannot be skipped.
  • the dialing aid consists of an arrangement of keys, which is to be referred to as a keypad.
  • a keypad can consist of a row of keys, or can also be formed from an arrangement - similar to the dial pattern of the H circuit.
  • the keys on a keypad can be designed to either snap in or as tip contacts. It is only important in the context of the invention that the keypad is constructed mechanically, electrically or electronically in such a way that only one key can be actuated at a time. With a keypad, you can choose as you would with a selector lever, which means that there is no prescribed sequence of dialing positions when dialing, but you can also skip individual gears. A direct change from a higher forward gear to reverse gear should, however, be prevented by suitable structural measures.
  • the redundancy position detection significantly increases the security of dialing.
  • dialing security is not only to be understood as the moment of the driver's dialing, but also the maintenance of the gear unit's dialing position. Every system that is to be further protected requires more effort. This is why a redundancy position detection is associated with a technical effort. For cost reasons, therefore, only a limited number of dial positions can be provided with redundancy position detection.
  • only the reverse gear is provided with a redundancy position detection.
  • it can be a forward gear group or just a single forward gear. However, not only gears (forward or reverse gears) can be monitored, but also one or more "stable positions" of the dialing aid.
  • Dialing pictures sometimes also have switch positions (for example labeled "A / M").
  • Such a changeover position allows a changeover - for example for the forward gear group - from automatic driving mode to manual driving mode. In manual driving, you could shift up or down, for example by tapping a selector lever.
  • a switch position can also be used to switch between moderate driving dynamics and sporty driving behavior of the motor vehicle. Therefore, a switch position is also an important selection position, which should be monitored for safety reasons.
  • At least one “stable position” is provided for the dialing aid.
  • a “stable position” in the sense of the invention is a position for the dialing aid in which there are no tasks or intentions on the part of the dialing aid to the control device of the transmission device - be signaled. All other required selection positions can be located around a “stable position”. If there are several “stable positions” in a selection screen, these "stable positions” are connected to each other via a neutral lane. Around each of these "stable positions” is a sensible one Grouping of the other dial positions arranged.
  • a neutral position is provided in the dialing image - and above all in the sensors of the position detection. With this neutral position, an actively engaged gear - be it a forward: - or a reverse gear - is selected.
  • this is equipped with a reset mechanism for the dialing aid.
  • This reset mechanism causes the dialing aid to return to the “stable position” after being released by the driver after a dialing process.
  • the resetting mechanism can consist of a suitable arrangement of springs and / or of a correspondingly shaped catch, where a spring - in connection with a catch means - can - at least partially - reduce its tension.
  • the sensors for the main position detection and the redundancy position detection function reliably.
  • a possible sensor would be electrical resistance. This electrical resistance could be influenced by a relative movement of the dialing aid to a base and thereby allow a dependent current to pass through (resistance as a potentiometer, for example). Depending on this current, electronics could determine whether a sensor is reporting a selector position or not.
  • the sensor consists of an electrical switch. An electrical switch can be designed as a break contact or as a make contact, but it can also have a blocking and a forward direction, for example as in the case of a transistor. In a further embodiment of the sensor, it is designed as an electrical / electronic circuit.
  • the senor is a Hall sensor educated. Hall sensors have the advantage that they can be operated very small, very reliably and very easily.
  • a sensor for example a Hall sensor, supplies an analog, constant current and / or voltage level when an electrical source is present, which can be influenced by an applied, external magnetic field.
  • an electronic circuit is required which can convert the level states into a bit pattern, that is, digital information.
  • the sensors of the main and redundancy position detection are connected to a control device via a data bus.
  • Preset codes are used for the control-related, logical detection of sensors or signals of the control device. These codes have a predetermined bit pattern. If one bit or several bits deviate from these preset codes, the controller can recognize that a corresponding sensor has failed. If the control device contains corresponding error-detecting codes, it can even determine the error and the location of the error.
  • Error-correcting codes in the control device can even be used to carry out signal “repairs”.
  • the data transfer between the sensor and the control device can be arranged by means of a channel coding.
  • the present invention also represents a method, because a desired selection position is selected by means of a selection aid, sensors of the main position detection and sensors of the redundancy position detection each deliver a signal, which their statements are compared with one another in a control unit, and if the statements are identical This selection position is confirmed for and in the control device.
  • a specific dialing position can be selected by means of a dialing aid by tapping the same.
  • a dialing aid for example around a selector lever, a short tap, for example on a plus symbol, is sufficient to either move from standstill to first gear or to move from a second to a third gear.
  • Dialing by tapping can also be used for different driving directions. It is advantageous here if a dialing aid automatically returns to a "stable position" after tapping.
  • Tapping a dialing aid as a dialing form can also be done in conjunction with touch sensors and non-latching buttons.
  • Another form of dialing is by turning a dial. This dialing represents a sequential dialing.
  • a sequential dialing means that the arrangement of dialing positions can only be carried out in a fixed prescribed sequence.
  • the control unit continuously checks whether the information about the current selector position has changed. If the dialing aid is, for example, a dialing aid that snaps into the dialing position, the sensors of the main and the redundancy position detection can deliver a continuous signal. If this control signal is permanently queried by the control device, information about the current dial position is available at all times. But even if the dialing aid is non-latching and the dialing aid is not locked in the dialing position, the sensors can influence, for example, memory areas of the control device through their brief activation during the dialing process.

But even if the dialing aid is non-latching and the dialing aid is not locked in the dialing position, the sensors can influence, for example, memory areas of the control device through their brief activ
  • the control system can assume that the current selector positions have not changed. Querying signals from the sensors that are only briefly during the dialing activated, can therefore be checked continuously because the signal from the sensors has been stored in memory areas of the control device. If you want to keep the monitoring effort for the current dial position as low as possible, you can only check the information about the dial position periodically.
  • a periodic check in connection with digital signals, in contrast to the permanent check, is countersigned in that in the case of a permanent check after the query of a specific bit pattern or a memory area, the check of a bit pattern or a memory area is continued without delay.
  • the signal is processed in an event-controlled manner. In this case, a level change (ie a change in the current / voltage value) of the signal would serve as the event trigger.
  • a motor vehicle with a transmission device according to the invention - or with the method according to the invention for operating this transmission device - must have measures which pose a danger or emergency situation Prevent people.
  • an emergency drive program of the transmission is activated. This emergency driving program provides, for example, that the vehicle can still drive to the edge of the road at reduced speed.
  • the emergency driving program can, for example, be designed in such a way that the driving mode valid in the control device - for example “D” - is maintained until the vehicle comes below a defined driving speed - for example 20 km / h the control device then forcibly selects the zero position, ie the gear selected.
  • the driver can also be warned about the incomplete function of his transmission until the vehicle comes to a standstill the control device, for example, are shifted to higher engine speeds. The otherwise unusual, high-speed engine noise would then cause the driver be warned and informed.
  • An optical (lamp) or an acoustic (buzzer) warming device can also draw attention to the defect.
  • the shift quality of the transmission device can also be significantly reduced, so that the driver is also warned and he visits the workshop as soon as possible.
  • an emergency braking program for the transmission is activated.
