Method and device for controlling an adjusting device of a motor vehicle

摘要

In order to control an adjusting device of a motor vehicle, in particular a window lift, having a motor-driven adjusting part, the speed of the drive is controlled to a desired speed value during normal operation at least in a sub-range of an adjustment travel and the driving force is controlled to a desired force value in the event of difficult motion for a first time period. After the first time period has ended, the adjusting part is reversed or the drive is at least stopped in the event of pinching. If the difficult motion is not an event of pinching, the speed of the drive is controlled anew to the desired speed value, wherein the driving force is first reduced to a first force and is increased to the desired force value within a second time period and/or a value realized during normal operation is used as a desired force value for the driving force.

主权项

1. A method for controlling an adjusting device of a motor vehicle, the adjusting device having a motor-driven adjustment component, which further comprises the steps of:
adjusting, at least in one part of an adjustment path, in a normal operating mode, a speed of a drive to a speed setpoint value; and adjusting, in a case of difficulty of movement, a drive force to a force setpoint value for a first time period, wherein, after an expiry of the first time period, performing at least one of the further steps of:
reversing the motor-driven adjustment component;stopping the drive if a risk of trapping is detected; oradjusting the speed of the drive again to the speed setpoint value if the case of difficulty of movement is not a case of trapping, wherein in a case of difficulty of movement the drive force is first reduced to a first force and increased to the force setpoint value within a second time period.
