METHOD FOR CONTROLLING AN AUTOMATIC TRANSMISSION OF A MOTOR VEHICLE |
摘要 |
The invention relates to a method for controlling an automatic transmission of a motor vehicle, in which method a gearspeed-holding function is activated by a driver request and is deactivated as a function of a return condition. In order to permit effective, operationally reliable and comfortable use and termination of the gearspeed-holding function, the return condition is determined using at least one of the following criteria or appropriate combinations formed therefrom: a) a flexible time period taking into account stationary times of the vehicle, b) an engine speed of a drive engine of the vehicle or of one or more of the variables correlated to the engine speed, c) a new driver request of the same type or of a different type, d) a change of an operating state of a vehicle, and e) a plausibility check taking into account a driving off process. |
