Description

The proposed solution relates to a vehicle with an electronic detection device and a method with which an electronic control signal is to be generated.

In particular from the US 2008/103660 A1 It is known to provide an electronic detection device in a vehicle, via which a vehicle state is detected which is representative of the fact that the vehicle has been parked and thus parked. In this context, in order to avoid inadvertently leaving someone in the vehicle who cannot leave the vehicle alone, for example a child or a physically and / or mentally handicapped person, it is also known to use an electronic detection device to identify a potential occupant presence to detect in a vehicle interior of the vehicle and, if necessary, to generate a control signal for an alarm, so that a driver or owner of the vehicle is promptly made aware that someone is still in the parked vehicle. Systems with such an electronic detection device and such an electronic detection device are also referred to as systems with what is known as child-left-behind detection, since this is intended in particular to prevent an infant or toddler from accidentally staying behind in a parked vehicle.

The one in the US 2008/103660 A1 proposed vehicle, different criteria are checked in a specific sequence in order to decide whether or not a control signal for outputting an alarm should actually be generated. As an alternative to generating an alarm, provision can be made to open a window in order to lower a temperature at least in the vehicle and to prevent a toddler or an infant remaining in the vehicle from being damaged due to overheating. The US 2008/103660 A1 basically assumes that after querying different predetermined criteria, only exactly one specific control signal is generated or not in order to trigger exactly one measure.

There is therefore a need for a vehicle and a corresponding method which are further improved in this regard.

Against this background, a vehicle is proposed in which at least two different control signals can be generated via an electronic control device in response to the detection of a vehicle state representative for parking the vehicle and the detection of a potential occupant presence depending on at least one additionally considered parameter.

The proposed solution is thus based on the one hand on the basic idea that at least two different control signals can be generated and thus at least two different measures can be triggered. On the other hand, in addition to a vehicle state representative for the parking of the vehicle and a potential occupant presence, at least one additional parameter is used that influences which of the at least two different control signals is generated and thus which action is taken by the electronic detection device, the electronic section device and the electronic Control device comprehensive (safety) system are initiated.

A vehicle state representative for the parking of the vehicle can be detected, for example, in that an identification element assigned to the vehicle, such as a transponder on a vehicle key, is no longer in the vehicle interior and / or in the surroundings of the vehicle and / or the vehicle (from the outside) has been completed, in particular after switching off a drive of the vehicle. The fact that an identification element assigned to the vehicle is no longer in the vicinity of the vehicle is detected here, for example, by the fact that the identification element is no longer present in a radius around the vehicle defined by a distance threshold value after previously, ie within a defined consideration period, the Identification element - and thus a person wearing this identification element - was still present in the vehicle interior.

The additionally considered parameter can be, for example, a measured time period, for example the time that has elapsed after the generation of a first control signal in order to generate a second, different control signal if the potential occupant presence is still detected.

The parameter can also be indicative of the fact that another control signal has already been generated beforehand.

Alternatively or in addition, an additionally considered parameter can be vehicle-specific. Such a vehicle-specific parameter can include, for example, a measured value that is indicative of where the vehicle is located, for example in the form of the vehicle-specific parameter shows a GPS position of the vehicle. The triggering of a certain measure can only be useful in certain places or, conversely, not be useful in certain places. For example, a measure that can be triggered via a control signal should not be triggered if the vehicle is not located in a defined area around a home address. For example, opening a window or motor-controlled opening of a vehicle door may not make sense if the vehicle is not at the home address of the vehicle driver, as this increases the risk that unauthorized persons can gain access to the vehicle.

A vehicle-specific parameter that is additionally taken into account can also be indicative of whether there is a child seat in the vehicle, for example. The detection device for detecting a potential occupant presence in the vehicle interior can then also take into account, for example, whether a potential occupant is currently in the area of the child seat. Alternatively or in addition, the electronic detection device can be set up to classify an object detected in the vehicle interior. The electronic detection device is thus set up, for example, to signal whether the potential occupant in the parked vehicle is a child or an adult.

However, a vehicle-specific parameter can also take into account a current time, a temperature (for example in the vehicle and / or outside the vehicle), and / or an environmental situation. In the latter case, for example, a possible triggering of the opening of a vehicle door is checked whether there is an obstacle and in particular another vehicle in an adjustment range of the vehicle door to be opened, or whether the vehicle was parked adjacent to a busy street in the direction of which the vehicle door would be opened .

For example, at least one control signal of the at least two different control signals of the electronic control device leads to an alarm, in particular to a visual and / or acoustic alarm. This includes in particular that the at least one alarm is triggered on the vehicle itself. If the presence of an occupant is detected when the vehicle is parked, one or more lights, for example in a headlight or indicator of the vehicle, and / or a horn of the vehicle can be activated. However, the at least one alarm can (also) be wirelessly transmitted to a computer device, in particular to a mobile terminal, or can be triggered on the computer device. An alarm can therefore not be triggered, or not only triggered on the vehicle itself, in order to generate attention in the vicinity of the vehicle. Rather, the alarm can also be transmitted to a remote mobile terminal, such as the mobile phone of at least one registered user, in order to indicate an occupant remaining in the parked vehicle, for example a toddler or an infant. A remote computer device can also be part of a server system and / or a type of control center via which specific measures are centrally controlled and triggered after the alarm is received. In this variant, measures can thus be controlled and, in particular, triggered from a remote computer device.

Alternatively or in addition, at least one adjustment component on or in the vehicle can be adjusted via at least one control signal from the electronic control device. Such an adjustment component is, for example, a window pane, a sliding roof, a vehicle door or a tailgate of the vehicle. A measure that can be triggered by one of the control signals is thus, for example, the opening of a corresponding adjustment component in order to cool down the vehicle interior if necessary. An adjustment component to be adjusted can also be a vehicle seat. For example, a first or second row of seats can be folded over automatically in order to make it easier to get out of a second or third row of seats in the parked vehicle.

Alternatively or in addition, an electronic component on or in the vehicle can be controlled via at least one control signal from the electronic control device. Such a controllable electronic component can, for example, be at least part of an air conditioning system, seat ventilation, a mobile radio unit, a hands-free device or an electro-transparent, in particular electrochromic, glass of the vehicle. For example, when a potential occupant presence is detected in the vehicle interior of the parked vehicle - for example after a certain time and / or as a function of an additionally detected interior temperature - an air conditioning system can be activated in order to cool the vehicle interior. The air conditioning system can in particular comprise an electric refrigerant compressor that can be operated independently of the motor drive of the vehicle in order to enable cooling of the vehicle interior even when the drive of the vehicle is switched off. As an alternative or in addition, seat ventilation can be activated to cool the vehicle interior and / or a pane or a panoramic glass roof can be darkened in order to minimize solar radiation. The control of an electronic component of a Mobile radio unit of the vehicle includes, for example, that a call is automatically triggered to indicate by telephone that an occupant may remain in the parked vehicle. For this purpose, a mobile device remains in the vehicle, for example, or the vehicle itself is equipped with a SIM card. If a hands-free device is activated, this can in particular enable the person remaining in the parked vehicle to seek help himself. The hands-free facility is consequently activated automatically in the corresponding situation via one of the control signals.

One embodiment variant of the proposed solution provides a control logic in the electronic control device which prioritizes the at least two different control signals that can be generated differently. A measure to be triggered via a control signal thus has a higher priority than another measure which can be triggered via another control signal. A higher prioritization of a specific measure can have the consequence, for example, that a control signal for this measure is repeated and in particular generated more frequently than another control signal of lower priority. For example, a high-priority call or alarm can be triggered more frequently and above all before seat ventilation is activated.

As an alternative or in addition, the at least two different control signals can be generated in a predetermined sequence. A certain sequence of control signals is stored in the electronic control device in order to trigger successive measures one after the other, e.g. to counteract a health impairment of a person remaining in the parked vehicle, in particular a child, and / or on the person remaining in the parked vehicle to draw attention. A cascade of control signals can therefore be triggered. Measures provided and controllable via the control signals can thus be generated in escalation stages in a predetermined time sequence in order to react in stages and using different measures to a person remaining in the parked vehicle. In this way, for example, an alarm can first be output before a window pane is lowered and / or an air conditioning system is activated if - after the alarm has been generated - it is not detected that the vehicle is being reopened and / or the person is leaving the vehicle interior. In this context, the at least one additionally considered parameter can be indicative, for example, that a control signal preceding in the sequence has already been generated. A corresponding value of the parameter is thus documented that another measure has already been taken and, for example, a certain time has passed, so that only then is the further, other control signal generated and thus another measure triggered.

In one embodiment variant, a prioritization and / or a sequence of the different control signals can be changed. This includes, in particular, that a user can individually determine which measures are taken in which order if a person is still detected in the vehicle interior when the vehicle is parked - for example after a certain period and / or at a certain interior or exterior temperature becomes. A prioritization and / or a sequence of the different control signals that can be generated can also be changed in an automated manner by the system itself. For this purpose, the control electronics can be configured, for example, to change the prioritization and / or the sequence of the control signals on the basis of the at least one additionally considered parameter. For example, from a certain temperature threshold, the activation of an air conditioning system and / or the opening of a window pane can enjoy a higher priority than the generation of a (specific) alarm in order to lower the temperature in the vehicle interior as quickly as possible.

As an alternative or in addition, the additionally considered parameter can be indicative of a current on-board electrical system voltage. In this way, for example, when the voltage drops, a specific measure to be triggered can be shifted further back in the sequence of the measures to be triggered. For example, opening a window or a vehicle door is provided earlier than activating an air conditioning system, although this increases the risk of access to the vehicle by unauthorized third parties, since the electrical energy required for this is less than for operating the air conditioning system.

Alternatively or additionally, the control electronics can be configured, based on the at least one additionally considered parameter, not to generate a control signal that is pending in a priority order provided by the prioritization and / or in the order for generation and instead a control signal that is actually lower in the order of priority and / or in to generate the control signal following the sequence. In this case, the ranking and / or order is consequently not changed permanently or temporarily, but rather at least one control signal to be generated in response to the at least one additionally considered parameter is skipped. For example, if the vehicle electrical system voltage is too low, the vehicle's air conditioning system is not activated. On The control signal can consequently be omitted and another measure can be triggered instead if this appears to be indicated on the basis of detected external circumstances for which the at least one parameter is indicative. For example, the opening of a vehicle door can be omitted if a busy road has been detected in the vicinity of the vehicle door.

The 1 shows with a view of a vehicle interior I. a vehicle F. , on the vehicle floor B. different vehicle seats 1 , 1a , 1b and 1c are arranged. In the vehicle interior I. are in the present case two different electronic detection devices by way of example 2a and 2 B for contactless monitoring of the vehicle interior I. depicted on the presence of a person. About these detection devices 2a and 2 B which include, for example, radar sensors, ultrasonic sensors or a camera, in particular a ToF camera, it is detected whether there is inside the vehicle interior I. another person is located when the vehicle F. was turned off. Sensors of the electronic detection devices 2a , 2 B can for example in a headliner or a center console of the vehicle interior I. or in a headrest of a vehicle seat 1 , 1a , 1b , and 1c be provided. In particular, sensors of the electronic detection devices 2a and 2 B only certain areas of the vehicle interior I. monitor, for example, only one row of seats, so that only one sensor or only a specific set of sensors is provided for each row of seats.

Parking the vehicle F. and an associated vehicle condition is detected via an electronic detection device 3 supervised. This detection device 3 is for example with the vehicle doors T1 to T4 of the vehicle F. coupled to electronically detect that the vehicle doors T1 to T4 are closed and locked. At the same time, the electronic detection device is present 3 with a transmitter-receiver unit 30th fitted. Via this transmitter-receiver unit 30th can the detection device 3 detect whether there is an identification element in the form of a mobile phone M. or a transponder ID (the e.g. part of a vehicle key for the vehicle F. is) when the vehicle is parked F. from the vehicle F. away. So can the detection device 3 using the transmitter / receiver unit 30th detect whether one has the transponder ID carrying person P. that were previously in the vehicle interior I. found from the vehicle F. away and for example one around the vehicle F. defined perimeter leaves.

Used after the vehicle has been parked F. and removing the person P. from the surroundings of the vehicle F. on conscious parking of the vehicle F. closed and yet via the electronic detection device 2a , 2 B another person in the vehicle interior I. detected, can via one with the detection devices 2a , 2 B and the detection device 3 coupled electronic control device SE a cascade of different measures can be triggered. This cascade of measures is aimed in particular at one in the vehicle interior I. any remaining child from health damage caused by accidentally remaining in the vehicle interior I. to protect.

The electronic control device takes into account the prioritization and sequence of the different measures that follow one another in time SE different parameter signals in the present case p1 to p4 as well as, if applicable, the fact whether a person is present at a vehicle seat 1c is detected on which a child seat is available. A parameter signal p1 can here for example indicative of an interior temperature in the vehicle interior I. be. A parameter signal p2 can be indicative of a GPS position of the vehicle F. be. A parameter signal p3 represents, for example, the signal of at least one environment sensor of the vehicle F. with the help of which one in the vicinity of the vehicle F. another parked vehicle or a possible obstacle in an adjustment range of an openable vehicle door T1 to T4 and / or a busy street in the vicinity of one or more of the vehicle doors T1 to T4 is detectable. With a parameter signal p4 it can be, for example, a signal that is representative of the vehicle electrical system voltage.

Taking these parameter signals into account p1 to p4 can the control device SE which integrates a control logic and a memory for this purpose, different control signals s1 to s4 produce. These control signals s1 to s4 trigger different measures. For example, on a control signal s1 an air conditioning system of the vehicle F. to be activated. On a control signal s2 can be an adjustment component of the vehicle F. can be controlled. For example, in response to the control signal s2 a window pane, at least one of the vehicle doors T1 to T4 , a sunroof or a tailgate of the vehicle F. be opened. Via a control signal s3 For example, an electro-transparent, in particular electrochromic, glass in a pane or a sliding glass roof of the vehicle F. controlled to darken the glass and thus the sunshine into the vehicle interior I. to reduce. Via a control signal s4 an alarm can in turn be triggered. So can the control signal s4 for example an acoustic and / or visual alarm on the vehicle F. and / or on one of the person P. worn mobile device M. trigger. Alternatively or in addition, the control signal s4 the mobile device M. be called and / or a speakerphone in the vehicle F. to be activated.

In particular, it can be provided that the electronic control device SE always at least one alarm signal to the mobile terminal M. and to a display in the vehicle F. generated to the person P. on a possibly parked vehicle F. to point out any backward child. If the vehicle is not unlocked within a specified period of time F. and / or removing the child from the vehicle interior I. at least one further measure is taken by the electronic control device SE triggered, such as activating the air conditioning and / or opening at least one window of the vehicle F. .

According to the representation of the 2 can be attached to a vehicle seat 1c a child seat 4th be fixed. This is in the area between a backrest 11 and a seat part 10 of the vehicle seat 1c a bracket 5 , for example a bracket of a so-called ISOFIX bracket accessible with which a locking arm 40 of the child seat 4th is locked. The retaining bracket 5 has a body connection or seat connection 50 to the child seat 4th crash-proof on the vehicle seat 1c to be determined. The vehicle-side retaining bracket 5 can also have a sensor to the electronic detection device 3 and / or electronic control device SE the occupancy of the vehicle seat 1c with a child seat 4th to signal. Alternatively or in addition, a seat occupancy sensor can be installed in the vehicle seat 1c be provided.

One for the presence of the child seat 4th and in particular the occupancy of the seat 1c with a child indicative parameter signal can then from the control device SE be taken into account in order to generate a ranking or sequence of control signals s1 to s4 to change. So can then for example in the electronic control device SE a ranking and / or sequence for a cascade of triggering measures depend on whether, in particular with the aid of the electronic detection device 2a and 2 B , for the presence of a child or an adult in the vehicle interior I. is closed.

Using the flow chart of the 3 is shown as an example, as when the vehicle is parked F. and detected occupant presence by the electronic control device SE a cascade of measures can be triggered. In a first step, for example, it is initially detected that the vehicle F. was turned off. This closes according to the representation of the 3 in particular one that is electronically recorded that the vehicle doors T1 to T4 were locked to an engine of the vehicle F. has been turned off and the transponder ID from the vehicle F. away. Is used following such a vehicle state of the vehicle F. a person and especially a child in the vehicle F. detected, checks the electronic control device SE furthermore on the basis of pending parameter signals p1 to p4 the extent to which certain measures of a given priority and / or order are to be triggered or can be triggered. As explained above, this includes that an alarm is always triggered initially, but then, for example, the opening of a vehicle door is dispensed with and only an air conditioning system is activated when a GPS position of the vehicle is present F. not - with a specified tolerance - with a stored home address (or something other than "safe" classified address) or the vehicle F. was parked next to a busy road.
