Abstract
The invention relates to a method and a device for controlling a standstill circuit of an automatic transmission of the vehicle, comprising a decision unit for selection of the target gear, a low-speed monitoring unit and a standstill circuit, which, when the vehicle is standing still or when its speed falls below a predetermined limit speed, brings about or prepares the activation of a starting gear.The method and the device are intended to enable a vehicle to start up safely even under the influence of considerable tractive resistance. Furthermore, they should be characterized by solutions which are as simple, inexpensive and easy to implement as possible by way of available methods and devices. To this end, the low-speed monitoring unit reads data concerning at least one state of the vehicle and, if necessary, additional data, and, on the basis thereof, as a function of decision rules, renders the standstill circuit ineffective.
