Embodiment Construction

[0037] exist figure 1 A motor vehicle 10 with a drive motor 12 is schematically shown in FIG. The control unit 14 with a microprocessor is designed to send control signals for operating the drive motor 12 and to receive signals from various sensors. Accelerator pedal 24 can be actuated by the driver of the motor vehicle.

[0038] Accelerator pedal sensor 16 provides a value for detecting the position of accelerator pedal 24 and sends it to control unit 14 . The rotational speed sensor 26 is provided for detecting the rotational speed value of the drive motor 12 and sending it to the control unit 14 .

[0039] Furthermore, a clutch unit 18 is provided, wherein a clutch pedal travel sensor 20 detects the actuation of the clutch pedal (not shown) and transmits a value rClth for the clutch position to the control unit 14 .

[0040] Speed ​​sensor 22 ascertains a value for the vehicle speed and sends it to control unit 14 .

[0041] The following is based on figure 2 The meth...

Abstract

The invention relates to a method for start-up support in a motor vehicle having a drive motor, comprising: detecting (S1) a possible start-up process; detecting (S2) a value (rClth) for the clutch position; comparing (S3) the detected value (rClth) to a predetermined first value range for the clutch position; and carrying out (S5) a start-up support if the detected value (rClth) lies within the first value range.

Description

technical field [0001] The invention relates to a method for starting assistance in a motor vehicle with a mechanical manual transmission. In particular, the invention relates to a method for avoiding false triggering of the start assist. Background technique [0002] In conventional methods for starting assistance, the starting process is assisted by providing an additional motor torque or an increase in rotational speed. As a result, false triggering can occur, for example, when switching on electrical loads or when actuating the power steering. This leads to speed overshoots, which can be detected not only visually (speed gauge) but also audibly. Contents of the invention [0003] The object of the present invention is to provide a method and a device for starting assistance in which false triggering is avoided. [0004] This task is accomplished by the method for starting assistance in a motor vehicle with a drive motor according to claim 1 , by the computer program...
