Definitions

  • the document DE 20 2017 103 702 U1 describes a vehicle that has a door opening mechanism for selectively releasing a vehicle door from a closed position and a door handle that is connected to the door opening mechanism, the door handle being arranged on the vehicle door, the door handle between a flush position in which an outside of the door handle is flush with a portion of an outside surface of the vehicle door immediately surrounding the door handle such that only the outside of the door handle can be accessed, and an extended position in which the outside of the door handle moved away from the outer surface of the vehicle door so that a rear surface of the door handle can be accessed.
  • the vehicle may include a motor located near the door handle to operate the door handle between the flush position and the extended position.
  • the vehicle described there has a heating mechanism which is in thermal communication with the outside of the door handle and the outside surface of the vehicle door which immediately surrounds the door handle; and a remote transmitter in communication with the heating mechanism, the remote transmitter selectively activating the heating mechanism.
  • a temperature sensor may be placed in communication with a handle portion of the vehicle door, the handle portion including at least one of the outside of the door handle and the outside surface of the vehicle door immediately surrounding the door handle, and wherein the heating mechanism is in communication with the temperature sensor.
  • the object of the invention is to provide a simpler solution for preventing a door handle from freezing.
  • the object is achieved by an arrangement with a vehicle door with a door handle for opening the vehicle door, which can be brought by means of a motor from a first position into at least one further position in relation to the vehicle door, with a door control unit that is set up to control the motor based on an actuation command to move the door handle, with environmental condition sensors arranged on or in the vicinity of the vehicle door, and/or with a position detection system and a weather information system, with an actuation control unit that is set up to receive environmental condition information from the environmental condition sensors and/or information from the To process position detection system in conjunction with the weather information system and cause the door control unit based on a processing result to operate the door handle at least once within a time interval if the processing result of the environmental status information indicates a risk of icing of the door handle.
  • This forced actuation can always take place when the environmental condition, based on the sensor system, indicates a temperature profile in which there is a risk of icing also due to the humidity, for example due to previous rain.
  • the actuation control unit can be part of the door control unit or another vehicle control unit, for example in a common control unit.
  • the actuation control unit can also be designed as a program that runs in the microprocessor of the common control unit.
  • the environmental condition sensors can be temperature and/or humidity sensors.
  • the actuation control unit can be set up to cause the door control unit to actuate the door handle according to a predefined movement pattern.
  • the actuation control unit can be set up to receive the predefined movement pattern from an external source.
  • the predefined movement pattern can also be stored in the actuation control unit or can be determined on the basis of the environmental status information from the environmental status sensors and/or information from the position detection system in conjunction with the weather information system.
  • the actuation control unit can be set up to prioritize the information differently when processing the environmental state information from the environmental state sensors and/or information from the position detection system in connection with the weather information system.
  • the first position of the door handle is a position in which the surface of the door handle is flush with the outer wall of the vehicle door.
  • FIG. 2 shows a procedure for determining a door handle movement requirement on the basis of environmental information.
  • FIG. 1 shows an actuation control unit 1 in a schematic manner, which can either be an independent control unit or part of another control unit installed in a vehicle.
  • This other control unit can, for example, be a door control unit, the task of which is to control the motorized movement of a door handle 5 or of the entire door in a known manner.
  • the door handle 5 can be motorized from a first to a second position, with its outside preferably being flush with the outside wall of the vehicle door in the first position, as is known, for example, from DE 20 2017 103 702 U1.
  • the actuation control unit 1 is connected to environmental condition sensors 2, which in particular can be temperature and/or humidity sensors. These can be installed on or in the vehicle door or at another suitable location on or in the vehicle. They are preferably arranged in the vicinity of the vehicle door handle 5 since the environmental condition in this area is mainly important for assessing whether there is a risk of the door handle 5 icing up.
  • environmental condition sensors 2 which in particular can be temperature and/or humidity sensors. These can be installed on or in the vehicle door or at another suitable location on or in the vehicle. They are preferably arranged in the vicinity of the vehicle door handle 5 since the environmental condition in this area is mainly important for assessing whether there is a risk of the door handle 5 icing up.
  • the actuation control unit 1 is connected to a position detection system 3 and a weather information system 4 present in the vehicle. It is thus possible to assess the risk of icing on the basis of the data received and to take the precautions according to the invention.
  • the actuation control unit 1 determines from the information received whether the temperature should or can assume values in the near future that are due to the Humidity or rain could lead to the door handle 5 icing up. In this case, it will instruct the door control unit to move the door handle 5 to prevent it from freezing.
  • the movement can take place once in a predetermined time interval or repeatedly with smaller movements, possibly also as a vibration, depending on which measure is found to be more suitable on the basis of the environmental information.
  • FIG. 2 shows a course of the assessment as to whether a predefined movement pattern should be initiated.
  • step S1 the data from the sensors 2 and/or the position detection system 3 and the weather information system 4 are received or read in and processed according to a predetermined and stored algorithm—step S2.
  • step S3 a decision is made as to whether the door handle 5 should be moved. If not, the information is obtained again in a step S4 and a new assessment of the hazardous situation is determined. If it turns out that the door handle 5 should be moved, this is done in a step S5 according to a movement pattern that is preferred for the current situation.
  • the invention uses the door handle's existing movement mechanism in combination with an environmental information source when performing movements to prevent the device from freezing. It should be noted that the local sensor solution and the information provided by a network connected device such as a TCU can either be used individually or complement each other.
  • the solution has the advantage that it not only depends on local information that the device can collect, but also on environmental forecasts.
  • the movement pattern can be predefined within the control unit or calculated dynamically on a server side.
  • An example of a motion action trigger is shown in Figure 2, a more complex implementation can be considered prioritizing the acquired/received data. While a single movement might be enough in certain situations, it puts more stress on the mechanism; reduced effort, but done more often, protects the mechanism and reduces the likelihood of excessive freezing.
  • the invention can be provided in the form of an application that is local to a vehicle control unit or as a service for a backend solution.
  • the invention is particularly useful in electric vehicles that experience significant range reduction from excessive heating consumption.
  • a TCU can be used as an information broker for the backend communication, the logic specific to the movement pattern can be implemented in different control units.
