Embodiment Construction

[0027] figure 1 The shift gate 10 of the selector lever 50 is shown schematically with a boundary region marked with a dotted line, which can trigger a warning signal. The gearshift gate 10 firstly has a gear selection groove 20, and the gear selection groove 20 is figure 1 The center runs from left to right and has three boundary areas 25, 26 and 27 for triggering warning signals.

[0028] exist figure 1 Among them, shift slots 30 to 36 are arranged perpendicular to the shift slot 20, and the shift slots 30 to 36 lead to each gear to be shifted, and in this embodiment, four A reverse gear R and six forward gears 1 to 6 are inserted into the three different positions 21 to 24, the shift gates can be inserted from the selector gate 20, wherein a boundary area 41 to 46 is respectively provided here, if the If the above-mentioned border zone should not be crossed, a warning signal is promptly and clearly triggered in the event of an incorrect operation.

[0029] First, the sh...

Abstract

The invention relates to a method for triggering a warning signal when an incorrect operation occurs during operation of a motor vehicle. The method includes the following method steps. First, the method is started by using a vehicle key or a vehicle code for starting the motor vehicle. Here, it is checked whether the shift lever is in the neutral position of the gear selector gate (20) of the shift gate (10) of the shift lever. If the situation in the previous step is negative, a warning signal is triggered, otherwise starting the vehicle engine is allowed. Whenever the position of the shift lever in the shift gate (10) changes, it is checked whether the change in engine speed exceeds a critical upper limit value or is below a critical lower limit value. If the situation in the previous step occurs, a warning signal is triggered, otherwise the shifting operation is allowed and continuous monitoring of the operating elements continues.

Description

technical field [0001] The invention describes a method for triggering a warning signal in the event of an incorrect operation of a motor vehicle. In particular, it is proposed to activate the warning signal when the selector lever in the selector gate presents a risk of incorrectly shifting gears. Background technique [0002] In all efforts to save fuel in motor vehicle operation, there is always the risk that, when shifting early into a higher gear, the necessary torque cannot be transmitted to the running gear via this gear, causing the engine and transmission to overwork. Run at low RPM until the vehicle experiences engine instability and stalls. In this driving mode, the transmission and the vehicle engine are subjected to high loads, which can lead to a considerable reduction in the service life of the transmission and the engine. On the other hand, erroneous maneuvers can thus occur when coasting downhill with gear or when shifting into a lower gear before the ligh...
