Description

The present invention relates to a control method for controlling heating of a steering wheel and/or a seat for a motor vehicle. The invention also relates to a control system for controlling heating of a steering wheel and/or a seat for a motor vehicle, a steering wheel for a motor vehicle, a seat for a motor vehicle and a motor vehicle.

In the currently publicly known state of the art for steering wheel heaters and/or seat heaters, the accidental activation of the heater, especially in the summer months, can create an uncomfortable situation or even panic in the user of the steering wheel, since the user's hands "glow" for reasons that are not apparent to the user.

For example, the said situation can occur if the steering wheel heating is activated by accidentally pressing the associated activation button on a multifunction steering wheel at a high outside temperature of 30°C in the shade due to an unfavorable steering movement. The activation of the steering wheel heating is usually not noticed at first. The sudden heat on the steering wheel is unexpected for the user and may also cause uncertainty as to the cause of the heat. A search for the cause of the heat represents a safety-critical distraction for the user of the motor vehicle. However, even deactivating the steering wheel heating does not provide an immediate remedy, since the thermal mass of the steering wheel continues to provide increased heat for a few minutes. Furthermore, when a steering wheel heater is activated, it usually starts with the highest heating level and the heating level is reduced by further keystrokes up to the point of deactivation. This means that further keystrokes are required before deactivation again after accidental activation.

This situation of the unintentional activation of the steering wheel heating and/or seat heating by actuating the steering wheel heating and/or seat heating, in particular on a multifunction steering wheel, is an overwhelming situation, especially for inexperienced drivers. An unwanted actuation with the consequences described above triggers at least one dissatisfaction on the part of the user of the motor vehicle.

It is therefore the object of the present invention to eliminate or at least partially eliminate the disadvantages in the prior art described above. In particular, the object of the invention is to provide a control method for controlling a heating of a steering wheel and/or a seat for a motor vehicle, with which activation of the heating is made possible in a particularly simple manner with fewer incorrect switchings of the heating. In particular, it is also the object of the invention to provide a control system for controlling heating of a steering wheel and/or a seat for a motor vehicle, a steering wheel for a motor vehicle, a seat for a motor vehicle and a motor vehicle.

The above object is solved by the patent claims. In particular, the object is achieved by a control method for controlling heating of a steering wheel for a motor vehicle having the features of independent claim 1. Furthermore, the object is achieved by a control system for controlling heating of a steering wheel for a motor vehicle having the features of independent claim 9, by a steering wheel for a motor vehicle with the features of independent claim 10, by a seat for a motor vehicle with the features of independent claim 11 and by a motor vehicle with the features of independent claim 12. Further advantages and details of the invention result from the subclaims , the description and the drawings. Features that are described in connection with the control method according to the invention naturally also apply in connection with the control system according to the invention, the steering wheel according to the invention, the seat according to the invention, the motor vehicle according to the invention and vice versa, so that the disclosure of the individual aspects of the invention is always referred to alternately will or can become.

• - Festlegen wenigstens eines Regelkriterium mittels einer Regelvorrichtung des Regelsystems,
• - Erfassen eines Betätigens einer Betätigungsvorrichtung des Regelsystems zum Schalten der Heizung durch die Regelvorrichtung,
• - Messen wenigstens einer Temperatur durch wenigstens einen Temperatursensor des Regelsystems,
• - Vergleichen der wenigstens einen erfassten Temperatur mit dem wenigstens einen Regelkriterium durch die Regelvorrichtung,
• - Regeln der Heizung in Abhängigkeit von dem Vergleichen durch das Regelsystem, wobei die Heizung in wenigstens eine erste Stufe geschaltet wird, wenn das wenigstens eine Regelkriterium erfüllt ist.

According to a first aspect of the invention, the object is achieved by a control method for controlling heating of a steering wheel and/or a seat for a motor vehicle with a control system, the control method having the following method steps:

• - defining at least one control criterion by means of a control device of the control system,
• - detecting an actuation of an actuating device of the control system for switching the heating by the control device,
• - measuring at least one temperature by at least one temperature sensor of the control system,
• - Comparing the at least one detected temperature with the at least one control criterion by the control device,
• - Controlling the heating as a function of the comparison by the control system, the heating being switched to at least a first stage if the at least one control criterion is met.

Unless explicitly stated otherwise, the method steps described above and below can be carried out individually, together, once, multiple times, at the same time and/or one after the other in any order. A designation as, for example, “first procedural step” and “second procedural step” does not require any chronological order and/or prioritization.

Within the scope of the invention, the heater is to be understood as a steering wheel heater and/or a seat heater. Exemplary configurations and features described below can each be implemented both for a steering wheel heater and for a seat heater.

The control system can be configured completely in and/or on a motor vehicle or can be configured separately from the motor vehicle at least in sections. For example, the temperature sensor is preferably arranged on the motor vehicle. A control device is preferably configured, at least in sections, by a computer unit that is separate from the motor vehicle. The assemblies and/or components of the control system are preferably connected to one another for data communication, in particular connected by cable or wirelessly. The actuating device of the control system is preferably designed as an operating device for switching on the heating by the control device. The actuating device is designed separately, for example as a button or touch surface, in a multifunction steering wheel and/or in a central control unit of a motor vehicle, such as a multifunction display. The at least one recorded temperature is compared with the at least one control criterion by the control device and determines, for example, whether the at least one recorded temperature is greater, less than or equal to the at least one control criterion. In said example, the control criterion is a fixed temperature value, this embodiment being described in detail in a later section. When comparing the at least one defined control criterion with the at least one measured temperature, the control device determines whether the control criterion is met or not. The temperature can be measured continuously, permanently during operation of the motor vehicle, with time variations and/or at time intervals. Controlling the heating as a function of the comparison by the control system is to be understood in such a way that the heating is switched to at least a first stage if the at least one control criterion is met as a result of the comparison. The core idea of the control method according to the invention is therefore to enable “clever” activation of the heating. The essence of the invention is that an actuation of an actuating device of the control system for switching on the heating triggers or at least queries a comparison of the at least one detected temperature with the at least one control criterion by the control device. The method step of comparing can take place in an energy-efficient manner only upon request or over a period of time, in particular while the motor vehicle is being used, or essentially over a period of time. In the context of the invention, the wording “X or essentially X” should be understood as a possible, small deviation, for example due to manufacturing tolerances, material and/or process properties, without changing the underlying, intended function of the feature. According to the invention, switching the heating on is preferably to be understood as switching on the heating. Alternatively or additionally, switching on the heating can also include switching up, down or switching off the steering wheel heating and/or seat heating.

A control method configured in this way for controlling a heating of a steering wheel and/or a seat for a motor vehicle is particularly advantageous, since activation of the heating is made possible in a particularly simple manner with reduced faulty switching of the heating, with faulty switching within the scope of the invention as switching the heating counter to a intention of the user are to be understood.

• - dass die Heizung nicht geschaltet wird, wenn das wenigstens eine Regelkriterium nicht erfüllt ist.

According to a preferred further development of the invention, it can be provided in a control method that the control also includes:

• - That the heating is not switched on if the at least one control criterion is not met.

An advantageous embodiment of the control method provides that the heating is not switched on if the at least one control criterion is not met. This has the advantage that the heating is advantageously prevented from being switched on unintentionally and no further action is required by the user of the motor vehicle in order to set the state of a switched-off heating.

According to a preferred further development of the invention, it can be provided in a control method that the control criterion includes at least one temperature value, in particular the control criterion being met during the comparison if the at least one recorded temperature is less than or equal to the at least one temperature value and the control criterion is not met is when the at least one sensed temperature is greater than the at least one temperature value. Alternatively, it should of course also be possible within the scope of the invention for the control criterion to be designed in such a way that the control criterion is met when the at least one detected temperature is lower the at least one temperature value and the control criterion is not met if the at least one detected temperature is greater than or equal to the at least one temperature value. As described above, the at least one recorded temperature is compared with the at least one control criterion by the control device and determines, for example, whether the at least one recorded temperature is greater, less than or equal to the at least one control criterion. In this advantageous embodiment, the control criterion includes at least one fixed temperature value. The control criterion can preferably also include changes over time in at least one temperature value, environmental conditions and/or data about the motor vehicle and/or the user. A control method designed in this way for controlling a heating of a steering wheel and/or a seat for a motor vehicle is particularly advantageous, since activation of the heating is made possible in a particularly simple manner with reduced faulty switching of the heating.

• - Messen von wenigstens einer Innentemperatur des Kraftfahrzeugs und/oder wenigstens einer Außentemperatur des Kraftfahrzeugs, insbesondere wobei das Vergleichen einen Vergleich der wenigstens einen Innentemperatur und/oder der wenigstens einen Außentemperatur mit dem wenigstens einen Regelkriterium umfasst.

According to a preferred further development of the invention, it can be provided in a control method that the measurement also includes:

• - Measuring at least one interior temperature of the motor vehicle and/or at least one exterior temperature of the motor vehicle, in particular wherein the comparison comprises a comparison of the at least one interior temperature and/or the at least one exterior temperature with the at least one control criterion.

An advantageous embodiment of the control method is when at least one internal temperature and/or at least one external temperature is measured. The data of at least one interior temperature and/or at least one exterior temperature advantageously define an actual situation of the user of the motor vehicle and/or the motor vehicle and thus represent a practical basis for the comparison with the at least one control criterion. The at least one temperature sensor can be configured on or separately from the motor vehicle, in particular the temperature sensor for detecting an internal temperature of the motor vehicle being of course arranged in the motor vehicle. A control method designed in this way for controlling a heating of a steering wheel and/or a seat for a motor vehicle is particularly advantageous since activation of the heating is made possible in a particularly simple manner with reduced faulty switching of the heating on the basis of advantageous temperature data.

According to a preferred further development of the invention, it can be provided in a control method that the regulation of the heating comprises switching the heating in at least two stages, the heating being switched to the first stage if at least one first control criterion is met, the heating in one second stage is switched on when at least a second control criterion or a first and a second control criterion are met and the heating is not switched on when the at least two control criteria are not met. According to the invention, switching the heating in at least two stages represents a preferred, more detailed switching of the heating. For example, switching the heating in at least two stages enables the heating energy of the heating to be graduated, in particular as a function of at least one measured temperature and/or of the at least one rule criterion. It is advantageous if even two control criteria are defined, so that a more detailed gradation of the switching of the heating is made possible as a function of at least one measured temperature and/or of the at least two control criteria. For example, if the measured temperature is higher than a first control criterion and above a second control criterion, the heating is only switched to a low first level, whereas if the measured temperature is lower than the second control criterion, the heating is switched to a higher second level. A higher stage of the heating is to be understood as a higher heating energy of the heating. For example, in said scenario, the heating is not switched on if the measured temperature is above the first control criterion. A control method designed in this way for controlling a heating of a steering wheel for a motor vehicle is particularly advantageous since activation of the heating is made possible in at least two stages in a particularly simple manner with reduced faulty switching of the heating.

• - Abfragen einer Benutzerbestätigung zum Regeln und/oder Schalten der Lenkradheizung, wobei bei einer gegebenen Benutzerbestätigung die Heizung nicht, insbesondere nicht erneut, geschaltet wird und bei einer nicht gegebenen Benutzerbestätigung die Heizung geschaltet, insbesondere erneut geschaltet, wird.

According to a preferred further development of the invention, it can be provided in a control method that the control method, in particular the control, also includes:

• - Queries a user confirmation for controlling and / or switching the steering wheel heating, with a given user confirmation, the heating is not, in particular not again, switched on and not given user confirmation, the heating is switched, in particular switched on again.

In order to advantageously further reduce faulty switching of the heating, the control method according to this embodiment provides for user confirmation to be requested for controlling and/or switching the heating. With a given user confirmation, the heating is not switched on, in particular not again, and not switched on with one given user confirmation switched the heating, in particular switched again. According to the invention, the user confirmation is to be understood, for example, as a renewed actuation of the actuating device or another device of the control system. The user confirmation is preferably haptic, acoustic and/or sensory. According to the invention, the query always takes place after the method step of regulation, so that regulation always takes place independently of the user confirmation. The query thus enables a confirmation or a reversal of the regulation that has already taken place. The user confirmation preferably requires an active or passive rejection of the user confirmation for a reversal of the switching of the steering wheel heating. In this case, an active rejection is to be understood as, for example, haptic, acoustic and/or sensory input by the user. A passive rejection is to be understood, for example, as an omission of an action, in particular with the user confirmation being automatically rejected by the control device after a specified time. A control method configured in this way for controlling a heating of a steering wheel for a motor vehicle is particularly advantageous since the heating can be activated particularly easily with fewer faulty switching operations of the heating and with simple reversal of unwanted control processes.

• - Ausgabe einer Anzeige durch eine Ausgabevorrichtung des Regelsystems, wenn ein Abfragen einer Benutzerbestätigung erfolgt.

According to a preferred further development of the invention, it can be provided in a control method that the query also includes:

• - Outputting a display by an output device of the control system when a user confirmation is requested.

It is particularly advantageous if the request for a user confirmation is indicated by the output of a display as a kind of reference to the request. The user of the motor vehicle is thus advantageously made aware of the query and the user confirmation and can promptly provide the user confirmation or reverse the regulation that has already taken place by not confirming or rejecting the user confirmation. According to the invention, the display can be configured optically, haptically and/or acoustically. The display is preferably designed as a separate and/or additional display in relation to the prompted user confirmation. A control method configured in this way for controlling a heating of a steering wheel and/or a seat for a motor vehicle is particularly advantageous since activation of the heating is particularly easy with fewer incorrect switchings of the heating and with simple reversal of unwanted control processes and at least one advantageous indication of the user confirmation becomes.

• - Ausgabe eines Schaltstatus durch eine Ausgabevorrichtung des Regelsystems, wobei ein erster Schaltstatus ausgegeben wird, wenn die Heizung in wenigstens eine erste Stufe geschaltet wird und ein zweiter Schaltstatus ausgegeben wird, wenn die Heizung nicht geschaltet wird.

According to a preferred further development of the invention, it can be provided in a control method that the control method also includes:

• - Output of a switching status by an output device of the control system, a first switching status being output when the heating is switched to at least a first stage and a second switching status being output when the heating is not switched.

It is an advantageous embodiment of the control method for the user of the motor vehicle if the switching status of the heating is output. The switching status is advantageously output visually, acoustically and/or haptically. The user of the motor vehicle thus advantageously receives feedback on the current switching status of the heating. This is particularly advantageous because the heating effect of the heater can usually be felt by the user with a time delay, and misjudgments about the switching state of the heater are thus advantageously reduced or avoided. The level to which the heating is switched is preferably displayed.

According to a second aspect of the invention, the object is achieved by a control system for controlling heating of a steering wheel and/or a seat for a motor vehicle. The control system has at least one temperature sensor for measuring a temperature, an actuating device for actuating the heater and a control device, the control system being designed to carry out the control method according to the first aspect.
