Definitions
- the invention relates to a method for operating a motor vehicle automatic transmission according to the preamble of claim 1.
- the aforementioned thrust downshifts are carried out, for example, when driving downhill to use the braking torque of a vehicle drive motor, so that the service brake of the vehicle is not subjected to excessive stress.
- tracking of transmission gears in accordance with the driving speed ensures that after the end of the overrun operating phase with the clutch engaged, the transmission gear that is required to carry out a positive vehicle acceleration phase that may then follow is engaged.
- a driving operation phase occurs in the normal driving operation of a motor vehicle, in which the driving If the driving speed is reduced to a traffic obstacle, a short-term, closed level crossing or a traffic light set to red. During such an operating phase, it can happen that the engine braking torque generated when the gearbox is engaged in a small gear exerts an excessive braking effect on the vehicle.
- the clutch is then opened to prevent the same from stalling.
- the vehicle rolls out with the transmission gear shifted high and the clutch open until the vehicle comes to a standstill and the appropriate starting gear is then engaged.
- This method for operating a Automatgetrie- bes has the disadvantage that it takes comparatively long time to 'the previous transition taken out, inserted the new gear, the clutch is engaged and the vehicle reacts with the desired vehicle acceleration.
- it is the object of the invention to present a method for controlling an automatic transmission the operation of which means that a suitable transmission gear is always shifted in the transmission during overrun downshift processes for immediate onward travel, without the disadvantages of the high engine braking torque at low driving speeds and high transmission ratios have to put up with in low gear gears.
- the invention proceeds from a method for operating an automatic transmission in a motor vehicle from, carried out be 'i which, during an overrun mode phase until a predefined limit speed downshifts in the transmission and are ended by closing of the clutch.
- Downshifts are completed below this limit speed with the clutch open, so that, depending on the driving speed and / or driving situation, the transmission gear is engaged at any time with which the drive on with a positive start drive torque can be carried out in the shortest possible time.
- the clutch which is open during the downshifts below the limit speed mentioned, also ensures • that despite the low gear, no braking torque is generated by the drive motor, for example an internal combustion engine.
- the limit speed mentioned is a vehicle-specific quantity that depends, among other things, on the gear ratios of the individual gear stages.
- gear jumps are preferably selected as a function of the vehicle deceleration, which is determined, for example, by measuring the change in the transmission output shaft speed. If the driver wants to continue driving and signals this request for a positive drive torque to the transmission control device by deflecting the power actuator of the vehicle, the clutch is closed immediately. Since the correct gear speed is already engaged, the driver experiences the desired vehicle acceleration without any noticeable delay.
- a preferred embodiment of the invention provides that these downshifts below the limit speed are only carried out if the vehicle continues to drive and thus the driver wishes for a positive drive torque for one given period of time is to be assumed as comparatively probable.
- special indicators are used to determine the probability of the driver's desire for a positive drive torque.
- Such an indicator can be, for example, a sensor signal with which the actuation of the service brake is displayed. As long as the driver operates the service brake, no comfort downshifts are triggered. Only when the driver releases the service brake, for example relieves the pressure on a brake pedal of the vehicle, are the comfort downshifts mentioned carried out with the clutch constantly open.
- the brake actuation is particularly suitable for this, since the driver normally takes his foot off the brake pedal to actuate the power actuator. The driver will brake his vehicle by pressing the brake pedal when approaching a red traffic light and relieve the brake pedal of the service brake when changing to green; to enable a further journey. If the driver then actuates the power actuator, the correct gear is already engaged at this time to suit the driving speed and / or driving situation, in order to either start from a standing start or to continue driving at a comparatively low speed. When the power actuator is actuated, only the clutch is then closed and it is possible to continue driving.
- signals can also be used as indicators for determining the driver's desire for a positive drive torque and thus for ending the overrun operating phase, which signals the deflection of the actuating lever for the direction indicator and / or an exceeding of the steering angle of the vehicle steering compared to a predetermined one Mark the steering angle.
- measuring the position of the actuating lever for the direction indicator is somewhat less meaningful but nevertheless expedient, since it is known that this is also deflected when the vehicle is decelerated to park at the edge of the road.
- the accuracy of the hit when analyzing the driver's behavior with regard to the drive torque requirements can be significantly increased by sharing two or more of the above or other indicators.
- a further improvement in the operation of an automatic transmission results from the fact that the engagement of the automatic transmission's starting gear is always ended with an open clutch at the end of an overrun operation phase, provided that only this transmission gear enables further travel.
- control mentioned is preferably stored as software in a transmission control device.
- This transmission control unit is as mentioned with .
- the transmission control device is signal-technically connected to sensors with which the transmission input speed, the transmission output speed, the actuation of the service brake, the power actuator and the direction indicator lever as well as the steering angle of the vehicle can be determined.
