Control device for a vehicle having an automatically closing hatch
View Patent ↗The control device relates to a vehicle having an automatically closing hatch, including at least one operating switch for outputting a closing command to automatically close the hatch by way of at least one actuator, a monitoring device for recognizing a blocking or jamming event during the closing procedure and a programmable electronic control unit which is connected with both the operating switch and the monitoring device, and which detects the vehicle speed as an input signal. The monitoring device is designed such that a risk of jamming can be recognized by monitoring the current curve and/or the rotational speed curve of the actuator. The control unit is programmed so as to only stop the closing procedure on recognition of a risk of jamming if the vehicle speed is less than a specified threshold value. Additionally or alternatively, the control unit is programmed so as to initially only react to the occurrence of comparatively large speed or current fluctuations by terminating the automatic closing procedure, for a certain time window and/or for a given distance covered by the tailgate, if the vehicle speed is above a specified threshold.
1. A control unit for a vehicle equipped with an automatically closing hatch, at least one operating switch that outputs a closing command to automatically close the hatch and at least one actuator configured to close the hatch, the control device comprising:
a monitoring device that recognizes a blocking or jamming event during a closing procedure of the hatch, the monitoring device being configured to recognize a risk of jamming by monitoring at least one of a current curve and a rotary speed curve of the actuator;
a programmable electronic control unit connected to both the operating switch and the monitoring device, wherein
the control unit receives an input signal of the vehicle speed, and
the control unit is programmed so as to only stop the closing procedure on recognizing, via the monitoring device, the risk of jamming if the vehicle speed is less than a predetermined threshold.
2. The control unit according to claim 1 , wherein
the control unit is programmed to ignore, at least for a certain time window or a certain travel distance of the vehicle, a vehicle speed present above the predetermined threshold of the current curve or the rotary speed curve of the actuator.
3. A control device for a vehicle equipped with an automatically closing hatch, at least one operating switch that outputs a closing command to automatically close the hatch, and at least one actuator configured to close the hatch, the control device comprising:
a monitoring device that monitors jamming during a closing procedure of the hatch, wherein the monitoring device is configured to recognize a risk of jamming by monitoring at least one of a current curve and a rotary speed curve of the actuator; and
a programmable electronic control unit connected to both the operating switch and the jam monitoring device, wherein
the control unit receives an input signal of vehicle speed, and
the control unit is programmed so as to initially only react to an occurrence of large rotary speed curve or current curve fluctuations by terminating the automatic closing procedure, for at least one of a certain time window and for a given distance covered by the hatch, if the vehicle speed is above the predetermined threshold.
4. The control device according to claim 3 , wherein the hatch is a rear hatch of the vehicle.
5. A method of controlling an automatically closing hatch of a motor vehicle equipped with an operating switch that outputs a closing command to automatically close the hatch via an actuator, the method comprising the acts of:
recognizing, via a monitoring device, a blocking or jamming event of the hatch during a closing procedure by monitoring at least one of a current curve and a rotary speed curve of the actuator; and
only stopping the closing procedure upon recognizing a risk of the blocking or jamming event if a vehicle speed is less than a predetermined threshold.
6. A method of controlling an automatically closing hatch of a vehicle equipped with an operating switch that outputs a closing command to automatically close the hatch via an actuator, the method comprising the acts of:
recognizing, via a monitoring device, a risk of jamming during the closing procedure by monitoring at least one of a current curve and a rotary speed curve of the actuator; and
initially only reacting to an occurrence of large speed or current fluctuations by terminating the automatic closing procedure, for at least one of a certain time window and for a distance covered by the hatch, if a vehicle speed is above a predetermined threshold.
