Abstract

A method for modifying a defined adaptive driving strategy, which is stored in the control system for an automatic transmission of a motor vehicle, for adaptation to another type of driver with a different driving style, consists in that the parameters used for the driving strategy are modified by the other driver, the data for this being input to the transmission electronics via an input unit and an interface with the electronics.

Claims

1. A method of modifying a predefined adaptive driving strategy stored in a transmission electronics system of an automatic transmission for a motor vehicle as a function of a plurality of vehicle parameters defining a first driving style of a first human driver, the method comprising the steps of:

modifying a first plurality of stored vehicle parameters representing at least a first driving style by at least one of;

manually modifying at least certain of the first plurality of stored vehicle parameters to form a second plurality of stored vehicle parameters representing a second driving style by manual input of vehicle parameter data under direct control of a human driver; and

automatically modifying at least certain of the first plurality of stored vehicle parameters to form a second plurality of stored vehicle parameters representing a second driving style by;

determining vehicle parameter data of the second human driver while the second human driver is driving the vehicle; and

inputting the vehicle parameter data of the second human driver to modify the vehicle parameters representing the first driving style to form the vehicle parameters of the second driving style; and

storing the modified vehicle parameters representing the first driving style as the vehicle parameters representing the second driving style.

2. The method according to claim 1, further comprising the step of using a modifiable evaluation parameter as a parameter for evaluation of a longitudinal acceleration.

6. The method according to claim 1, further comprising the step of using a modifiable evaluation parameter as a filtering parameter for an upper driving activity specification limit and for a lower driving activity specification limit.

7. The method according to claim 1, further comprising the step of using a modifiable evaluation parameter as a filtering parameter for at least one contribution of the individual evaluations of the parameters that characterize a particular human driver type and a human driver'"'"'s driving style and the vehicle and a way the vehicle drives.

8. The method according to claim 1, further comprising the step of using a modifiable evaluation parameter as a parameter for curve recognition.

9. The method according to claim 1, further comprising the step of using a modifiable evaluation parameter as a parameter which blocks an upshift of the automatic transmission when an accelerator pedal of the motor vehicle is released spontaneously.

10. The method according to claim 1, further comprising the step of using a modifiable evaluation parameter as a parameter which triggers a forced downshift when the vehicle decelerates spontaneously.

11. The method according to claim 1, further comprising the step of using a modifiable evaluation parameter as a parameter which increases the driving activity when an accelerator pedal is depressed rapidly.

12. The method according to claim 11, further comprising the step of increasing a driving activity by increasing an evaluation counter.

13. The method according to claim 1, further comprising the step of modifying the evaluation parameters by applying a delay time to the evaluation parameters.

manually inputting required data for the modifying of the parameters into transmission electronics by the data input unit and an interface with the transmission electronics; and

automatically modifying the parameters to modify a dynamic behavior, depending on one of an actual driving activity of the human driver or contributions of individual evaluation functions.
