Abstract
An indicating system for an automatic motor vehicle transmission is described which includes second indicating elements in addition to first indicating elements for indicating a preselected driving step. The second indicating elements, particularly during a semi-automatic operating mode of the motor vehicle transmission with a manual preselection of the gear steps, displays an actually shifted gear step. The first and second indicating elements are advantageously arranged in two vertical parallel rows in an indicating instrument of the motor vehicle.
Claims15
An indicating system of an electronically or electrohydraulically controlled motor vehicle multi-speed transmission, said transmission having a selector lever for the preselection of a driving position in which are engaged individual or several automatically shiftable driving gears in a fully automatic operating mode and a semi-automatic operating mode in which the driving gear may be selected manually, said indicating system including:
- first displaying means for displaying the preselected driving position corresponding to the selector lever position by means of first indicating elements marked by alphanumerical symbols, and
- second displaying means for displaying an indication of a driving gear that is currently engaged, said second displaying means including second indicating elements which are viewable separately from and simultaneously with the first indicating elements;
- wherein the first and second indicating elements are spaced from one another;
- and
- wherein the second indicating elements are controlled only during the semi-automatic operating mode with a manual selection of the driving gears.
An indicating system of an electronically or electrohydraulically controlled motor vehicle multi-speed transmission, said transmission having a selector lever for the preselection of a driving position in which are engaged individual or several automatically shiftable driving gears in a fully automatic operating mode and a semi-automatic operating mode in which the driving gear may be selected manually, said indicating system including:
- first displaying means for displaying the preselected driving position corresponding to the selector lever position by means of first indicating elements marked by alphanumerical symbols, and
- second displaying means for displaying an indication of a driving gear that is currently engaged, said second displaying means including second indicating elements which are viewable separately from and simultaneously with the first indicating elements;
- wherein the second indicating elements are controlled only during the semi-automatic operating mode with a manual selection of the driving gears;
- and
- wherein at least the first indicating elements are arranged corresponding to a shifting diagram of the selector lever.
An indicating system of an electronically or electrohydraulically controlled motor vehicle multi-speed transmission, said transmission having a selector lever for the preselection of a driving position in which are engaged individual or several automatically shiftable driving gears in a fully automatic operating mode and a semi-automatic operating mode in which the driving gear may be selected manually, said indicating system including:
- first displaying means for displaying the preselected driving position corresponding to the selector lever position by means of first indicating elements marked by alphanumerical symbols, and
- second displaying means for displaying an indication of a driving gear that is currently engaged, said second displaying means including second indicating elements which are viewable separately from and simultaneously with the first indicating elements;
- wherein the second indicating elements are controlled only during the semi-automatic operating mode with a manual selection of the driving gears;
- and
- wherein the first indicating elements and the second indicating elements are respectively arranged in rows relative to one another so as to correspond to an arrangement of first and second shifting paths which are connected with one another by means of a transverse path and extend in parallel to one another, the first shifting path being used for the preselection of the driving positions in the fully automatic operating mode, and the second shifting path being used for the preselection of the driving gears in the semi-automatic operating mode, and the selector lever, in the second shifting path, being guided in the manner of a rocker-type shifting arrangement in such a manner that, when the selector lever is swivelled into one direction (+) from a neutral center position located in the area of the transverse path and constructed as a stable inoperative position, the preselection of the driving gear may be increased by one gear respectively, and when the selector lever is swivelled into another direction (-), may be decreased by one gear respectively.
