Definitions

  • the invention relates to a method for controlling a switching operation between two - arranged between a transmission input shaft and a transmission output gears of a provided in a drive train with an accelerator pedal controlled engine of a motor vehicle transmission by means of a switching path between a currently engaged and a newly engaged gear under Overcoming a synchronization threshold of a synchronization device of a gear actuator by means of a predetermined synchronizing force displaced switching element.
  • the actually applied, acting on the switching element synchronous force can not be detected directly, so that it is determined on the basis of the function of the gear actuator modeling models.
  • a direct feedback of the synchronous force and thus their control for direct compensation of the variance of parameters and disturbances, such as drag torque in the transmission are not possible.
  • the object of the invention is an advantageous development of a method for controlling a shift sequence, in particular against the background of an improvement in the shifting comfort of the transmission.
  • the object is achieved by a method for controlling a switching operation between two gears arranged between a transmission input shaft and a transmission output shaft of a transmission provided in a drive train with an internal combustion engine of a motor vehicle controlled by an accelerator pedal by means of a gear shifting between a currently engaged and a newly engaged gear
  • a synchronization threshold of a synchronization device by a gear actuator by means of a predetermined synchronizing force displaced switching element solved, the synchronous force is set depending on a deviation of a differential speed gradient between the transmission input shaft and transmission output shaft of a target value.
  • the target value is determined at least as a function of an accelerator pedal value of an accelerator pedal and a differential speed of a transmission shaft determined from a target rotational speed of the newly engaged gear and a current rotational speed, taking into account the gear ratio difference between the gears.
  • the target value can be determined as a function of a currently set driving mode of the motor vehicle. This can be predetermined, for example, by the driver and / or automatically determined by control parameters derived from the driving style of the driver.
  • Particularly advantageous may be during a circuit continuously updated determination of the differential speed gradient, so that time and / or location-dependent switching path or the switching time can be adapted to a changing synchronous force.
  • short-term for example, operating temperature-dependent
  • wear-related effective adaptations of the switching force on the switching force curve can be provided.
  • further operating parameters of the motor vehicle such as operating temperature, mileage, damage indices of the circuit and the like can be detected and evaluated. It has proven to be sufficient if the determination of the speed difference underlying differential speed at the beginning of a synchronous phase of a switching operation is determined.
  • a target synchronous force can be determined.
  • this target synchronous force of the gear actuator is controlled, wherein when setting this target synchronous force by means of the gear actuator, the switching process described in particular its synchronous operation of the new gear to be engaged on the difference between the actual Differenzfitieregradienten and target value is compared.
  • the synchronous parameter can be adapted depending on the magnitude of the deviation of the target value and / or target synchronous force. If, for example, the actual differential speed gradient is greater than the target value, the reciprocal of the efficiency, ie the synchronous parameter, is adapted in the direction of smaller values.
  • the invention will be explained in more detail with reference to the single FIGURE.
  • This shows a block diagram of the control routine 1 for controlling a shift sequence for switching a newly engaged gear, after the current gear engaged is designed.
  • the synchronizing force Fsync is calculated from the synchronization torque Msync and the synchronous parameter as well as the hardware dependencies of both the transmission actuator (eg locking force) and the transmission (eg the mass inertia of the transmission input shaft) stored in block 3.
  • the synchronous parameter is hereby provided as the differential speed gradient determined in block 4, such as the differential speed deviation per unit of time.
  • the synchronous parameter is derived as a function of the detected variables of the synchronous time Tsync, the differential speed at synchronous start (Ndiff @ SyncStart) and the ratio for the gear to be engaged, the driver's request derived from the accelerator pedal position of the accelerator pedal and, if appropriate, the driving mode and optionally taking into account further influences Target differential speed NDiffTgt determined. From the target differential speed NDiffTgt, the target value of the synchronous force is further derived. In block 5, the speed difference gradient is stored as a characteristic curve in the form of the synchronous parameter and compared with a characteristic curve in the form of target variables of the synchronous parameter.
  • the synchronous parameter is adapted in block 6 and stored, for example, in a non-volatile memory, so that, for example, variables of the synchronous parameter changed by wear for the next switching sequences up to, if applicable re-adaptation immediately available.
  • the synchronous force obtained by means of the synchronous parameter in block 2 serves as a target variable for controlling the actuators such as gear actuator in block 7.
  • a synchronous speed vsync can be determined in block 8 using corresponding characteristics, which is also provided in block 7.
