ABSTRACT:
To detect the shift position of a motor vehicle transmission (1), the invention teaches that by means of sensors (17), the position of a shift lever (7) which shifts the transmission (1) is measured in the neutral path of a shift pattern of the transmission which corresponds to the neutral position of the transmission (1). The direction of the displacement into the gears which are located in pairs in the shift paths of the transmission is measured by means of shift lever contacts (23), which respond when the shift lever (7) is displaced from the neutral shift position. An evaluation circuit (25), as a function of the signals from the sensors (17) which, in the neutral shift position of the transmission, detect the shift path which has been selected and the signals from the shift lever contacts (23) which detect the direction of displacement, delivers a shift position signal which identifies the shift position instantaneously engaged. The speed ratio of the input shaft (3) and the output shaft (5) of the transmission (1) determined by means of speed sensors (33, 35) is compared in the evaluation circuit (25) to the transmission ratio specified by the design of the transmission for the shift position selected. When the speed ratios coincide, the gear is assumed to be engaged. Since in the transmission (1), only the shift position of the shift lever (7) in the neutral shift position is monitored, the sensors or switches (17) used for this purpose can have large actuation range tolerances.
