Description

[0001] The invention relates to a motor vehicle with a passenger compartment for at least one occupant, with at least one sensor device for detecting the occupant's location in the passenger compartment, at least one restraint device for securing the occupant in their location, and with a control device for activating the at least one restraint device based on a signal from at least one impact sensor of the motor vehicle. The invention further relates to a method for operating such a motor vehicle.

[0002] To ensure the restraint of vehicle occupants, current regulations require that each occupant wear a seat belt. Even if the vehicle is equipped with an airbag system, occupants are still required to wear seat belts. Such seat belts are particularly effective in the event of abrupt braking, ensuring the occupant's safety. This braking maneuver can be intentional or unintentional, such as when the vehicle collides with an obstacle.

[0003] German patent DE 10 2018 102 868 A1 describes a restraint system for a vehicle, comprising two vest panels that enclose the torso of a seated occupant and are connected at their free ends by buckles and clamps. The vest panels are coupled to belt retractors mounted on the vehicle seat via webbing straps. The belt retractors allow the detachably connected vest panels to be tightened, thus restraining the occupant in the vehicle seat. The vest panels have inflatable chambers. In the event of a vehicle impact, an impact sensor transmits a corresponding signal to a control unit. Furthermore, an occupancy sensor transmits a signal to the control unit indicating whether the seat is occupied and the size of the occupant. Depending on the size of the occupant, corresponding chambers of the vest panels are inflated by an inflation device controlled by the control unit.

[0004] However, even with such a restraint system, it is necessary for the seat occupant to wear a belt-like restraint device in the form of the interconnected vest strips.

[0005] A disadvantage here is that, to ensure the safety of the vehicle occupant, it is necessary for them to fasten the seatbelt that encompasses both sides of the vest. This results in a restriction of movement for the vehicle occupant.

[0006] In the future, however, automated driving will become increasingly important. Therefore, the focus is shifting more and more towards performing non-driving-related tasks alongside actual driving. This is especially true when operating a vehicle at a level of autonomy. 4 or Level 4 of automated or autonomous driving. At the autonomy level 4This involves a high degree of automation, where the system permanently takes over the control of the vehicle. Only when the system can no longer handle driving tasks can the driver be asked to take over control of the vehicle.

[0007] Particularly in highly automated driving situations, a certain degree of freedom of movement for the vehicle occupant(s) is advantageous. However, it is still essential to ensure the safety of the vehicle occupant(s).

[0008] Seatbelt systems are unable to provide occupants with the desired freedom of movement during autonomous driving. Furthermore, seatbelts can be incorrectly fitted or forgotten. Wearing a seatbelt can also be uncomfortable for the occupant. Finally, seatbelts can limit the overall experience and benefits of autonomous driving if the occupant wants to perform non-driving-related activities while wearing a seatbelt.

[0009] The object of the invention is to create a motor vehicle of the type mentioned above which offers the vehicle user a particularly high degree of freedom of movement and safety, and to provide a corresponding method for operating a motor vehicle.

[0010] This problem is solved according to the invention by a motor vehicle with the features of claim 1 and by a method with the features of claim 10. Advantageous embodiments of the invention are the subject of the dependent claims and the description.

[0011] A motor vehicle according to the invention has a passenger compartment for at least one occupant and at least one sensor device for detecting the occupant's location within the passenger compartment. At least one restraint device of the motor vehicle serves to secure the occupant in their location. The motor vehicle has a control device for activating the at least one restraint device in response to a signal from at least one impact sensor of the motor vehicle. The at least one restraint device is designed to secure the occupant in a location within the passenger compartment that is different from a vehicle seat.

[0012] In other words, activating at least one restraint device allows the vehicle occupant to be restrained and protected from injury even when the occupant is not seated in the vehicle. This means the occupant is not a seated passenger. Instead, the occupant can move freely within the passenger compartment without being restricted by a seatbelt. Specifically, if the at least one impact sensor detects an impending or occurring collision with an obstacle, the control unit activates the at least one restraint device. This restraint device then secures the occupant in their position within the passenger compartment, preventing injury.Consequently, the motor vehicle offers the vehicle user both a particularly high degree of freedom of movement and safety.

[0013] In particular, the passenger compartment provides at least one occupant with freedom of movement, for example, by allowing them to leave one seat and move to another, or to stand in a different location within the passenger compartment than the next seat. Despite this increased freedom of movement, the occupant's safety is guaranteed. This allows the occupant to engage in non-driving-related activities with ease.

[0014] Furthermore, the vehicle occupant is not required to wear a seatbelt, whether seated in a vehicle seat or located elsewhere. This is because the restraint system, which can be activated by a signal from at least one impact sensor, ensures the occupant's secure restraint even if they are not wearing a seatbelt, for example, in the event of a collision with an obstacle or another vehicle.

[0015] The at least one sensor device for detecting the location of the vehicle occupant in the passenger compartment can, in particular, comprise at least one camera, wherein the vehicle occupant can be identified and their location in the passenger compartment determined by evaluating images captured by the camera. The camera is preferably coupled to the control unit.

[0016] Preferably, the motor vehicle has multiple restraint systems. The control unit is designed to select, depending on the occupant's location, at least one restraint system from among these multiple systems for activation, ensuring that the occupant can be secured in their position. This ensures that not an unnecessarily large number of restraint systems need to be activated.

[0017] On the other hand, this approach ensures a particularly reliable and comprehensive guarantee that the restraint devices used to secure the respective vehicle occupant do not interfere with each other. Consequently, a highly situation-appropriate and targeted restraint of the vehicle occupant at their current location is achievable.

[0018] At least one restraint device can include a gripping arm that can be moved from a stowed position to a functional position by activation. In the functional position, the gripping arm at least partially encircles the vehicle occupant. Activating at least one such gripping arm can reliably prevent the vehicle occupant from colliding with components located in the passenger compartment of the vehicle, for example, in the event of a collision. This significantly reduces the risk of injury to the vehicle occupant.

[0019] Additionally or alternatively, at least one restraint device may include a retaining strap that can be tensioned between a first and a second attachment point by activation. Such a retaining strap also allows the vehicle occupant to be securely fixed or restrained in their current position to prevent injury, particularly from collisions with harder interior components of the passenger compartment. At least one of the attachment points may be equipped with a device for tightening the retaining strap.

[0020] The first attachment point can be located on a side panel of the vehicle, and the second attachment point on a component of the vehicle's seat. By tensioning the strap between these attachment points, a particularly situation-appropriate restraint or fixation of the vehicle occupant can be achieved.

[0021] This also applies if, additionally or alternatively, the attachment points are designed on the respective components of spaced-apart vehicle seats. For example, a safety strap stretched between the backrests of a driver's seat and a front passenger seat can restrain or secure a vehicle occupant who is located in the rear of the vehicle in front of a rear seat. This applies analogously if the stretched safety strap extends from the side wall of the vehicle to, for example, the base of a rear seat.

[0022] Additionally or alternatively, the first attachment point can be located on a first pillar of the vehicle, and the second attachment point on a second pillar opposite the first, in the direction of the vehicle's transverse axis. Such an attachment of the restraint strap is also advantageous for restraining or fixing the vehicle occupant in their position.

[0023] For example, a safety strap can run between the B-pillars of a vehicle when under tension. In its untensioned state, the safety strap can be routed, for instance, along the roof of the vehicle. Specifically, the safety strap can be guided into position through a slot or a predetermined breaking point in the headliner, where it then runs from one B-pillar to the opposite B-pillar and is under tension.

[0024] The tensioned safety strap can also run from one vehicle pillar in the direction of the vehicle's transverse axis to a diagonally opposite vehicle pillar, for example, from one of the B-pillars to a C-pillar. Furthermore, the tensioned safety strap can have attachment points on a vehicle pillar on the one hand and on a component of a vehicle seat on the other.

[0025] Additionally or alternatively, at least one restraint device can include a clamp with a first leg and a second leg. The clamp can be moved from an open position to a closed position by activation. In the closed position, the clamp at least partially encloses the vehicle occupant. Such a restraint device is also particularly well-suited to securing the vehicle occupant in their current position in such a way that, for example, in the event of a collision with an obstacle, injury to the vehicle occupant is largely prevented.

[0026] Additionally or alternatively, at least one restraint system can include an airbag, which can be moved from a stowed position to a deployable position by activation. In the deployable position, the airbag is filled with an inflation medium. Moving the at least one airbag into the deployable position also ensures that the vehicle occupant is restrained in their current location. This is because the at least one airbag prevents the vehicle occupant from moving in the direction in which the airbag provides impact protection to a particularly large extent.

[0027] Preferably, the airbag is attached to the roof of the vehicle and / or to the back of a seat. Such an airbag is particularly effective at securing, restraining, or fixing a vehicle occupant in their location, even if they are not seated in the vehicle.

[0028] In particular, a gas supplied by a gas generator and / or a gas stored under high pressure in a gas storage tank can be used as the filling medium for filling the at least one airbag or gas bag.

[0029] In the inventive method for operating a motor vehicle, the location of a vehicle occupant within the passenger compartment is detected by means of at least one sensor device of the vehicle. The vehicle occupant is then secured at their location by means of at least one restraint device of the vehicle. For this purpose, a control unit of the vehicle activates the at least one restraint device in response to a signal from at least one impact sensor of the vehicle. The at least one restraint device secures the vehicle occupant at a location within the passenger compartment other than a vehicle seat. In this way, a particularly high level of safety can be ensured even for a vehicle occupant moving freely within the passenger compartment, i.e., for a vehicle occupant not seated in a vehicle seat.Nevertheless, the vehicle user is afforded a very large freedom of movement in the passenger compartment.

[0030] The advantages and preferred embodiments described for the motor vehicle according to the invention also apply to the method according to the invention and vice versa.

[0031] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own.

[0032] The invention will now be explained in more detail with reference to preferred embodiments and the drawings. The drawings show: Fig. 1. In a schematic representation, a motor vehicle which collides with an obstacle, wherein vehicle occupants located in a passenger compartment of the motor vehicle are secured in their respective positions by means of various restraint devices; and Fig. 2. In a highly schematic way, another situation is described in which vehicle users standing in the passenger compartment of the motor vehicle or car are restrained at their respective locations by means of respective restraint devices in such a way that the occurrence of injuries to the vehicle users is avoided.

[0033] Fig. Figure 1 shows a highly schematic representation of a motor vehicle designed as a passenger car in the exemplary embodiment. 1 with a passenger compartment 2 The motor vehicle 1 is shown in a situation in which the motor vehicle 1 an obstacle 3impacts. A corresponding direction of travel of the motor vehicle. 1 is in Fig. 1 by an arrow 4 illustrated. The motor vehicle 1 is equipped with multiple impact sensors, one of which is an impact sensor 5 shown in an exemplary and schematic way.

[0034] Such impact sensors 5 Accelerometers and / or pressure sensors or similar devices can be used. In particular, at least one such impact sensor can be used. 5 It will be determined whether there is a negative acceleration of the motor vehicle. 1 exceeds or will exceed a threshold value at which, without taking appropriate measures, there is a risk of impairment to the safety of vehicle occupants or vehicle users 6 to be assumed.

[0035] In Fig. 1 are exemplary and schematic vehicle users 6or occupants in the passenger compartment 2 of the motor vehicle 1 shown. The vehicle users 6 include a driver who is seated in what is designated as a driver's seat 7 trained vehicle seat of the motor vehicle 1 sits. Furthermore, as a vehicle user 6 a child schematically depicted sitting in a rear vehicle seat 8 of the motor vehicle 1 sits. In an area between the driver's seat 7 and the rear vehicle seat 8 of the motor vehicle 1 is located in the passenger compartment 2 of the motor vehicle 1 another vehicle user 6 , who kneels in front of the child and occupies the child, who is in the rear vehicle seat 8 sits.

[0036] In Fig. Figure 1 shows a situation in which the control device or control unit 9a signal from at least one impact sensor 5 It receives a signal and then activates a number of restraint systems. These restraint systems ensure the safety of the respective vehicle occupants. 6 to fix them at their respective locations in such a way that in the event of the impact of the motor vehicle 1 on the obstacle 3 no injury to vehicle users 6 comes.

[0037] For example, in Fig. 1 airbag each 10 shown which are filled with a filling medium and thus brought into their functional position. These airbags 10 are on a roof 11 of the motor vehicle and protect the respective vehicle user 6 before an impact on hard components inside the passenger compartment 2 The control unit 9 This ensures that those airbags 10 be activated, i.e., from a storage position into the Fig. 1. Functional position shown, which are capable of assisting the respective vehicle user 6 at his respective location in the passenger compartment 2 to protect against injuries.

[0038] To determine the respective location of the vehicle users 6 in the passenger compartment 2 to detect, the motor vehicle 1 at least one sensor device 12 on, which in Fig. Figure 1 is shown schematically. For example, the sensor device 12 be designed as a camera, by means of which the location or position of the respective vehicle user can be determined. 6 in the passenger compartment 2 can be recorded.

[0039] For example, the control unit activates 9 the airbag 10 , which is located in the area of ​​the roof 11 above the rear vehicle seat 8 is arranged to protect the vehicle user6 in the form of the rear vehicle seat 8 to protect a seated child from injury. It is not necessary, for example, that the child sitting in the rear vehicle seat... 8 Once seated, fasten a seatbelt. Rather, the control unit ensures 9 activated restraint systems ensure that, depending on the respective location in the passenger compartment 2 and depending on the situation of the respective vehicle user 6 is appropriately restrained or detained at his respective place of residence.

[0040] For example, the control unit activates 9 in addition to or as an alternative to the airbag 10 a tether 13 , which is located in the area of ​​a backrest 14 of the rear vehicle seat 8 at the respective attachment points 15 is fixed. One of the attachment points 15 is in Fig. 1 shown schematically. By tensioning the retaining strap. 13 between the areas in the backrest 14 trained fastening points 15 is used to restrain the person sitting in the rear vehicle seat 8 vehicle occupants or vehicle users present 6 in the form of the child. As in Fig. As shown in 1, the tether strap can 13 the vehicle user 6 to secure or fix the child, particularly in the area of ​​its torso.

[0041] Additionally or alternatively, a bracket is schematically shown here. 16 shown which the legs of the person sitting on the rear vehicle seat 8 grabs the child in the rear vehicle seat 8 to fix. The clamp 16 or such a gripping mechanism could, for example, consist of a component of the rear vehicle seat 8to be deployed in order to detect the child's location on the vehicle seat 8 upon impact with the obstacle 3 to ensure the child is properly restrained.

[0042] The vehicle user as well 6 , which has its back to the driver's seat 7 has turned towards and is turned towards the child, on the one hand by means of a storage position in the roof 11 of the motor vehicle 1 integrated airbags 10 and on the other hand by means of a clamp or a gripping arm 17 fixed to his location, which was previously determined by means of the sensor device 12 was recorded.

[0043] The gripper arm 17 For example, it can be stored in a backrest. 18 the driver's seat 7 be accommodated and in its Fig. 1. The schematically shown functional position depicts the vehicle user kneeling in front of the child.6 grasp the torso area. Furthermore, it is possible to use the gripper arm 17 in its storage position in the area of ​​a side wall 19 of the motor vehicle 1 (compare Fig. 2) to accommodate.

[0044] The vehicle user as well 6 in the form of the driver, who is in the driver's seat 7 Once seated, it is secured, on the one hand, by means of a roof-mounted device. 11 of the motor vehicle 1 held airbags 10 and furthermore by means of a driver's airbag 20 He is restrained at his location. Furthermore, the driver is also secured torso using a gripping arm. 17 fixed in his seated position. Additionally or alternatively, in the area of ​​the legs or lower legs of the vehicle user. 6 in the shape of the driver a bracket 16 to ensure it is fixed in place.

[0045] Even the one in the driver's seat7 seated vehicle users 6 There is no need to wear a seatbelt. Rather, the restraint system in the form of the roof-mounted restraint system ensures safety. 11 held airbags 10 , of the driver's airbag 20 , of the gripper arm 17 and the bracket 16 for the fact that in the event of the impact of the motor vehicle 1 on the obstacle 3 the driver is restrained in such a way that injury to the driver as a result of the impact with the obstacle is prevented. 3 is avoided particularly extensively.

[0046] Regarding the motor vehicle 1 is therefore available to vehicle users 6 the opportunity was offered to sit in the passenger compartment 2 of the motor vehicle 1 to move freely and without wearing a seatbelt, without being confined to a position. Despite this freedom of movement, the necessary safety of the vehicle occupants is ensured. 6 for example in the case of a vehicle collision 1on the obstacle 3 This is ensured by the restraint systems described here as examples.

[0047] Especially using the example of the vehicle user kneeling in front of the child 6 It is evident that there is something in the motor vehicle 1 the vehicle users 6 or that occupants are able to move freely in the passenger compartment 2 to move without being subject to any restriction regarding posture and / or position.

[0048] This is particularly advantageous when the motor vehicle 1 is designed for autonomous or automated driving. In such an autonomous driving mode, preferably at least one control unit of the motor vehicle takes over. 1 independently performs accelerations and decelerations, lane changes, changes of direction, and the like.

[0049] Even if the respective vehicle user6 in such an autonomous driving mode of the motor vehicle 1 dedicated to activities unrelated to driving, in the event of an accident or if the body of the respective vehicle user needs to be restrained for other reasons 6 the respective vehicle user 6 or occupant adequately protected. Because the control unit 9 Activated restraint systems help prevent injuries. The first step in this process is to determine whether at least one vehicle occupant is present. 6 in the passenger compartment 2 is located, and the position or whereabouts of the vehicle user is determined. 6 This is detected by at least one sensor device. 12 accomplished.

[0050] In the next step, the vehicle user will be identified. 6by using the restraint devices mentioned above as examples, or by activating these restraint devices as appropriate in the passenger compartment 2 of the motor vehicle 1 fixed, ensuring that injury is avoided as much as possible.

[0051] Therefore, the data relevant to the vehicle user's location will be used. 6 and those belonging to the respective vehicle user 6 Appropriate measures were applied or taken in response to the position adopted. In any case, however, the restraint of the vehicle user is essential. 6 in the passenger compartment 2 regardless of whether the vehicle user 6 on a vehicle seat such as the driver's seat 7 or the rear vehicle seat 8 is located or at a location different from such a vehicle seat.

[0052] Also in Fig. 2 is the passenger compartment 2of the motor vehicle 1 schematically represented, with a first vehicle user 6 for example, in the form of an adult person in front of a back seat 21 of the motor vehicle 1 and behind a backrest 18 the driver's seat 7 is stationary. In the event of a collision of the motor vehicle. 1 on a (in Fig. 2 (obstacle not shown) 3 will this vehicle user 6 on the one hand by an airbag 10 fixed in its location, which is on the back of the backrest 18 the driver's seat 7 is held.

[0053] Furthermore, an airbag ensures 10 , which is located at a (in Fig. 2 (not shown) roof 11 of the motor vehicle 1 may be considered to be for the protection of the head of this vehicle user 6 Furthermore, in Fig. 2 schematically a gripping arm 17shown, which, for example, is from the backrest 18 the driver's seat 7 can extend to accommodate this stationary vehicle user 6 to at least partially grasp it and thus fix it in its location.

[0054] Very schematic is in Fig. 2. Furthermore, a restraint device in the form of a clamp. 16 shown which had a first leg 22 and a second thigh 23 includes end areas or free ends of the legs. 22 , 23 can in an opening of the bracket 16 be spaced apart from each other and in a closed position of the bracket 16 moved further towards each other. This allows the clamp to... 16 for securing at least one part of the vehicle user's body 6 to ensure this, for example by at least partially clasping this body part.

[0055] If the ends or free end areas of the legs22 , 23 in the closed position of the bracket 16 Contacting the vehicle also requires completely enclosing at least one part of the vehicle user's body. 6 using the clamp 16 possible.

[0056] As another vehicle user 6 is in Fig. 2. A child was shown sitting in front of a cushion. 24 the back seat 21 This vehicle user is standing. 6 Firstly, it is equipped with an airbag. 10 fixed to his location, which consists of one of the side walls 19 of the motor vehicle 1 has been released.

[0057] Furthermore, the passenger compartment is described below. 2 Child shown standing, secured by means of a tether 13 secured to his location. The tether 13 extends from the side wall 19 is the motor vehicle 1 towards a supporting structure of the seat cushion24 the back seat 21 . At appropriate attachment points 15 on the side wall 19 on the one hand, and on the supporting structure of the seat cushion 24 On the other hand, the tether strap 13 defined. Accordingly, fastening points can be determined. 15 of the tether 13 on the side wall 19 and approximately in the middle of the seat cushion 24 the back seat 21 be trained. By tensioning such a safety strap. 13 Can this be done in front of the seat cushion? 24 the back seat 21 The standing child must be restrained in their place of residence.

[0058] Furthermore, in Fig. 2 schematic sections of vehicle pillars, present in the form of B-pillars 25 , 26 of the motor vehicle 1 shown. For example, a (in Fig. 2 (not shown) tether 13It is planned that it will extend from the first B-pillar. 25 to the direction of the vehicle's transverse axis 1 opposite B-pillar 26 extends. At the B-pillars 25 , 26 This allows for the respective attachment points to be used. 15 of the tether 13 must be trained. This also includes the tensioning of such a device, for example between the B-pillars. 25 , 26 of the motor vehicle 1 The running retaining strap can fix or restrain the respective vehicle user. 6 to support or effect change at his place of residence.
