An object of an embodiment of the present invention is to improve the detection of a shift position of a gearshift lever of a motor vehicle transmission.

This object is achieved by an arrangement having the features of claim 1. Claims 10, 11, 12 and 15 provide a corresponding method, system, motor vehicle or computer program product under protection. Advantageous embodiments of the invention are the subject of the dependent claims.

According to one aspect of the present invention, for detecting a shift position of a gearshift lever of a motor vehicle transmission, in particular by a passage selection detecting means arranged therefor, an arrangement of the gearshift lever is detected in one of a plurality of lanes in which the gearshift lever is disposed, and, in particular by a passage area-detecting means arranged for this purpose, a deflection of the gear shift lever in the alley, in particular in streets (longitudinal or extension) direction and / or from a zero or neutral position and / or one of two, in particular opposing, deflections, detected, as well as a pairing of the detected deflection and the detected lane assigned to a switching position.

By linking a detected lane and a detected deflection within the lane, in one embodiment, a switching position can advantageously be detected, in particular with less equipment and / or signaling expense. In particular, a first shift position and a detected deflection in a first direction or first deflection can be assigned a first shift position or be, the same detected first lane and a detected, in particular opposing detected deflection in a second direction or a second deflection a second Shift position, a detected second lane and a detected deflection in the first direction, a third shift position, the detected second lane and the detected deflection in the second direction, a fourth shift position and so on.

Accordingly, according to one aspect of the present invention, an arrangement for detecting a shift position of a gearshift lever of a motor vehicle transmission includes a lane selection detecting means for detecting a lane in which the gear shift lever is disposed, and a lane area detecting means for detecting a displacement of the gear shift lever arranged in a lane , According to a further aspect of the present invention, a system for detecting the switching position to an arrangement described herein and a device which is signal-connected with the Gassenwahl- and lane detection means and, in particular hardware and / or software, in particular programmatically, for performing a is set up here described method.

The motor vehicle is in one embodiment, a passenger car. In one embodiment, the motor vehicle transmission has a mechanical or manually operable, in particular actuated, manual transmission, in particular a manual transmission. In one embodiment, the motor vehicle transmission has at least four, in particular at least five, in particular at least six, forward driving gears. The shift lever is in one embodiment mechanically, in particular via one or more traction means, in particular shift cables, or linkage coupled to the motor vehicle transmission. In one embodiment, each gear of the motor vehicle transmission is associated with a corresponding shift position of the gearshift lever or arranged the gear shift lever in this shift position when the corresponding gear is engaged or will.

In one embodiment, the gearshift lever is movable in at least or exactly two, in particular at least substantially orthogonal, directions, in particular rotatable or pivotable. In a development of the gear shift lever is mounted in a ball or universal joint. Additionally or alternatively, the gearshift lever is guided in a form-fitting manner by a shift gate, which has sliding lanes. Accordingly, lanes into which and / or which the gearshift lever can be arranged or deflected, in particular can be positively defined by a link.

In one embodiment, or at least one of at least or exactly one first, second and third forward-driving lane is or can be detected or detected, in particular by the lane-selection detection means arranged for this purpose. Accordingly, in one embodiment, the lane selection detecting means is arranged for alternatively detecting at least or a first, second and third forward lane lane. As a result, at least five forward driving gears or shift positions assigned to them can be detected in one embodiment.

In one embodiment, the lane selection detecting means comprises a first lane selector switch operable, in particular actuated, by the gearshift lever disposed in the first forward lane aisle, and a second lane selector switch characterized by that in the second forward lane switch; Fahrgang-alley gear shift lever arranged is actuated, in particular is operated. In one development, these switches are single-stage or can have exactly two possible states, for example ("0", "1"), ("low", "high") or the like. As a result, in one embodiment, the apparatus and / or signaling complexity can be reduced.

Generally, in one embodiment, a single stage switch may output exactly one signal, for example "1", "high" or the like, especially when actuated. In another embodiment, a single stage switch may output exactly two signals, for example "1", "high" or the like, when actuated, and "-1", "1/2" or the like when not actuated is or will, in particular, to monitor its operability even when not actuated switch.

In a further development, the first and second gate selector switches can not be actuated or actuated by the gear shift lever arranged in the third forward gear alley. As a result, at least three forward-lane aisles can be distinguished in one embodiment with low apparatus and / or signal complexity: is or is the first lane selector switch operated by the gear lever, so this is arranged in the first forward-lane alley, is the second Gassenwahl switch operated by the gearshift lever, so this is located in the second forward-lane alley, is or is neither the first nor the second lane selector switch operated by the gear shift lever, so this is in the third forward-lane alley arranged.

In one embodiment, the first lane selection switch is additionally actuated by the gearshift lever disposed in a reverse lane aisle. This can be detected by a corresponding reverse detection means. Then, in a development, only one possible arrangement of the gear shift lever in the first forward-driving lane is detected if the gearshift lever actuates the first lane selection switch. Specifically, in one embodiment, an arrangement of the gearshift lever in the reverse vehicle lane is detected if the gearshift lever actuates the first lane selector switch and the reverse detection means detects an arrangement of the gearshift lever in the reverse vehicle lane, and an arrangement of Gear shift lever in the first forward-driving lane detected if the gearshift lever actuates the first lane selector switch and the reverse detecting means detects no arrangement of the gearshift lever in the reverse lane alley. In particular, in this context it should be noted that the numbering of lanes, deflections and driving means no restriction on the generality, in particular no order or the like.

Single-stage switches, on the one hand, and two-stage or multi-stage switches, on the other hand, differ accordingly in one embodiment in that a single-stage switch can only display or indicate two states, in particular "actuated" and "not actuated", a two-stage or multi-stage switch corresponding to at least three Conditions, in particular "actuated", "differently actuated" and "not actuated. In this case, in each case a non-actuated state can be output both by a missing signal and, in particular for monitoring the functionality, by a control or basic signal.

In one embodiment, the lane area detection means includes a first lane area switch operable, in particular actuated, by a displacement of the gearshift lever in a first direction or a first displacement of the gearshift lever, and a second lane area switch provided by a deflection the gear shift lever in a, in particular opposite directions, second direction or one, in particular opposing, second deflection of the gearshift lever is actuated, in particular is actuated. These switches are single-stage in a further development. As a result, in one embodiment, the apparatus and / or signaling complexity can be reduced.

In a further development, the first and second lane-area switches can not be actuated or actuated by the gearshift lever which is not deflected from a zero or neutral position. As a result, at least three positions in one or more lanes, in particular at least two forward driving gears and the neutral position within a forward driving lane, can be distinguished in one embodiment with little apparatus and / or signaling expense: the first lane switch is or is actuated by the gearshift lever, it has a first deflection or is or is a forward drive engaged. If the second lane-area switch is or is actuated by the gearshift lever, then this has a second deflection or another forward lane gear is engaged. If neither the first nor the second lane area switch is actuated by the gear lever, this is not deflected or arranged in the neutral position.

Additionally or alternatively, in one embodiment, the lane area detecting means comprises a two-stage or multi-stage lane-area switch operable differently by a first deflection of the gearshift lever, a second deflection of the gearshift lever, and an undeflected position of the gearshift lever in the neutral position; outputs a first signal, for example "+1", when the gearshift lever is deflected in the first direction, outputs a second signal, for example "-1", when the gearshift lever is deflected in the second direction, and outputs no or a third signal, for example, "0", when the gearshift lever is not deflected from the neutral position. As a result, in one embodiment, the space can be reduced.

In one embodiment, deflections of the gearshift lever in at least two, in particular all, lanes are detected by the lane area detection means, in particular the same switches of the lane area detection means. Accordingly, in one embodiment, the lane area detection means is arranged for detecting a deflection of the gear shift lever in at least two, in particular all, lanes. As a result, the installation space and / or apparatus and / or signaling expenditure can be reduced in one embodiment.

In one embodiment, an arrangement of the gear shift lever in a reverse vehicle lane is detected by an additional reverse detection means. Accordingly, in one embodiment, the assembly includes additional reverse sensing means for detecting an arrangement of the gearshift lever in a reverse vehicle lane.

Likewise, the reverse detection means may also directly detect an engaged reverse gear and, based thereon, an arrangement of the gear lever in a reverse gear alley.

In one embodiment, one or more of the switches of the lane selection detection means and / or the lane area detection means are contact-based switches. A contact-based switch can be switched in one embodiment by touching, in a further development by engagement or pressing. In one embodiment, the contact-based switch is yielding, in particular elastic, in particular by a spring stored. As a result, in one embodiment, tolerances and / or oversizes in the adjustment paths can be compensated.
