Description

The present approach relates to a method and apparatus for preventing occupants from traveling sick of a vehicle and a vehicle having a device.

To increase the comfort of occupants while driving in a vehicle different vehicle systems can be controlled.

The EP 2 343 203 A2 describes a method for controlling the operation of a motor vehicle, wherein at least one vehicle system is controlled in consideration of the respective current operating state, in particular driving state, descriptive data for increasing the comfort of a passenger of the motor vehicle. In this case, in particular decoupling of a seat of the passenger is controlled as the vehicle system.

Against this background, the present approach provides an improved method and apparatus for preventing vehicle occupant travel for a vehicle as well as a vehicle having a corresponding apparatus according to the main claims. Advantageous embodiments will become apparent from the dependent claims and the description below.

The advantages achievable with the presented approach are that a suspension setting of a vehicle can be adjusted depending on a occupant occupancy of the vehicle. This is advantageous since occupants, also referred to as passengers, can be prone to travel sickness, especially in a rear area of the vehicle. This may e.g. occur when steering in addition to the steering on the front and on the rear axle or other settings by active suspension systems influence on vehicle movements. Therefore, different suspension settings can be used, depending on whether only the driver or passenger seat is occupied or the rear of the vehicle is occupied.

A method of preventing passenger inactivity of a vehicle has a step of reading in and a step of providing. In the reading-in step, an occupant signal is read in which represents at least one recognized occupant and in particular its position in the vehicle. In other words, occupant occupancy is represented by the occupant signal. In the providing step, a setting signal is provided for setting at least one characteristic of at least one landing gear setting of at least one chassis system of the vehicle. Here, the adjusting signal is provided which is adapted to set a first characteristic when the occupant signal indicates only a driver as the recognized occupant and / or set a second characteristic when the occupant signal at least one or more passengers, in particular their position in one indicate further area, in particular the rear of the vehicle recognized occupants in the vehicle.

This method can be implemented, for example, in software or hardware or in a mixed form of software and hardware, for example in a control unit.

The vehicle may be a passenger transport vehicle, for example a passenger car. It may also be a small car or microcar, in which due to a small center distance increased travel sickness may arise. The occupant signal may include one or more electrical signals or data. A detected occupant may be understood to mean that an occupant is at a recognized position in the vehicle. Thus, the occupant signal can indicate an occupancy of the seats of the vehicle. In particular, the occupant signal can indicate whether only the driver's seat is occupied or whether at least one seat in the rear area of the vehicle is occupied in addition to the driver's seat. The suspension setting may be a variable adjustment of a suspension system, for example, a steering angle of a rear axle of the vehicle. The rear area can be understood as a rear area of the vehicle, also called the rear, or an area behind a driver's seat. The rear area may include one or more passenger seats. The first characteristic may be a characteristic suitable for ordinary driving operation of the vehicle with only one driver and set. The second characteristic may be a characteristic suitable for driving operation of the vehicle and set when an increased probability of traveling sickness is expected because an occupant is in the rear area. The second characteristic is therefore tuned to increase ride comfort for the occupant in the rear area. The adjustment signal may alternatively or additionally be configured to adjust the second characteristic when the occupant signal indicates an occupant in the vehicle recognized in a passenger seat of the vehicle. Also, a passenger may be associated with increased sensitivity to travel sickness towards a driver. Thus, a range of functions of the chassis system may be limited in the second characteristic compared to the first characteristic.

In the providing step, the setting signal adapted to adjust the suspension system characteristic of the suspension system formed as a front and / or rear axle steering device and / or an electric stabilizer may be provided. Such suspension systems can influence the well-being of the occupants during operation and / or during vehicle operation. In particular, a set steering angle of the Hinterachslenkeinrichtung, which can be controlled while driving to increase agility and / or reduce a turning circle, can negatively impact on a seated in the rear area occupant due to an entering Momentanpolverschiebung the vehicle. In a vehicle with steerable wheels on only one axis (in a car usually the front axle), all wheel axles meet in Momentanpol M. The vehicle moves without sliding of the wheels in the plane and passes through the curve without pushing over the wheels , With additional movement of the vehicle in the plane (sliding) there is a Momentanpolverschiebung (eg in a supplementary steering on another axle or on slippery roads, etc.).

By means of the electric stabilizer tilting and / or rolling of the vehicle can be influenced, for example by driving at least one shock absorber of the vehicle.

It is advantageous if, in the step of providing, the setting signal is provided which is designed to set as the characteristic a characteristic curve and / or a limit value of the chassis adjustment of the chassis system. Here, for example, a limitation of a possible steering angle of the front and / or Hinterachslenkeinrichtung changed, for example, increased or reduced. So it can be specified a maximum steering angle. As the characteristic, for example, a gear ratio between a driver's steering request or a controller and a steering angle of the front and / or rear steering device to be set can be changed. Such measures can for example be increased in a curve of the ride comfort for the occupants in the rear area.

In the providing step, the adjusting signal adapted to set, as the first characteristic, a first threshold and / or a first characteristic, or to set a second threshold and / or a second characteristic as the second characteristic may be provided. In this case, the first limit value may differ from the second limit value and / or the first characteristic curve may differ from the second characteristic curve. For example, the first limit value can release a larger functional range of the chassis system, for example a larger maximum steering angle or a greater maximum steering speed, than the second limit value. This allows a modified driving operation, advantageously a more comfortable driving operation, when an occupant has been detected in the rear area, compared to a driving operation with only one against travel sickness insensitive driver occupied vehicle.

For example, in the step of providing, the adjusting signal may be provided, which is designed to set the characteristic of the suspension system of the chassis system that is shaped as a steering angle and / or a stroke and / or a speed. Also set strokes and / or speeds, such as adjustment speeds of the steering angle or stroke, can affect the well-being of the occupant in the rear area negative. For example, in this case the second characteristic can be set in order to limit a possible stroke to be set, for example to reduce or increase it and / or limit a speed at a setting, for example to reduce it, in order to ensure increased ride comfort for the occupant in the rear area, for example in cornering situations.

In the step of reading in, the occupant signal can be read in, in which the detected occupant was detected using a seat occupancy recognition, in particular a seat contact switch. Seat contact switches allow, for example, a quick and easy and reliable detection and assignment of occupants. It can be used on usually already installed in the vehicle seat contact switch. This makes it possible to recognize at which position the respective passenger (s) are located.

It is furthermore advantageous if, in the step of providing, the setting signal is provided which is configured to set the second characteristic, which is designed to prevent or minimize an instantaneous displacement of the vehicle during a steering situation. In particular, a superimposition of adjusted steering angles of the front axle and the rear axle of the vehicle, wherein these two steering angles may differ from one another, may cause such instantaneous displacement of the vehicle, which may cause or increase the rear passenger's travel sickness. It is thus helpful to prevent or minimize the expected instantaneous pole displacement of the vehicle.

The method may include a step of receiving in which a situation signal is received, representing a boundary situation. At this time, by using the situation signal, the adjusting signal adapted to set the first characteristic or a third characteristic different from the second characteristic may be provided. In this case, the situation signal may be assigned a higher relevance than the occupant signal. Thus, the first or third characteristics can be adjusted even when an occupant is in the rear area. Under the limiting situation, for example, an unstable driving behavior of the vehicle may indicate an evasive maneuver and / or an entry or exit parking situation of the vehicle. In such a limit situation, it may be advantageous to completely or at least substantially remove restrictions with regard to the functional scope of the chassis system. For example, the third characteristic can release a full range of functions of the chassis system. As a result, the suspension system can be optimally used to safely guide the vehicle in critical driving situations. Also, the full range of functions for solving special tasks, such as parking, can be provided. Thus, the limit situation can be understood as a dangerous situation in which a full range of functions of the chassis system of the vehicle should be usable and should not have any limits or characteristics specially set for driving comfort. A driving safety can therefore be given a higher relevance, as a prevention of travel sickness. As the third characteristic, a characteristic suitable specifically for such a border situation or danger situation and / or evasive maneuvers and / or a parking or Ausparkituation situation and / or predetermined characteristic can be understood. Even when parked or parked is a full range of functions of the chassis system, in particular the steering angle settings, advantageous.

The approach presented here also provides a device which is designed to perform, to control or to implement the steps of at least one variant of a method presented here in corresponding devices. Also by this embodiment of the approach in the form of a device, the approach underlying the approach can be solved quickly and efficiently.

A device may be an electrical device that processes electrical signals, such as sensor signals, and outputs control signals in response thereto. The device may have one or more suitable interfaces, which may be formed in hardware and / or software. For example, in a hardware configuration, the interfaces may be part of an integrated circuit in which functions of the device are implemented. The interfaces may also be their own integrated circuits or at least partially consist of discrete components. In a software training, the interfaces may be software modules that are present, for example, on a microcontroller in addition to other software modules.

A vehicle has the presented device. The device may for example represent a control unit or be integrated into an existing control unit. The vehicle may be configured to adjust a suspension setting of the vehicle depending on a occupant occupancy of a rear area or a driver's seat of the vehicle, in order to prevent or reduce rear passenger's travel sickness.

1 shows a schematic side view of a vehicle 100 with a device 105 for preventing passenger sickness from occupants 110 of the vehicle 100 according to an embodiment.

The device 105 is designed to reduce the travel sickness of inmates 110 to prevent or at least minimize a likelihood of the occurrence of travel sickness. For this is the contraption 105 designed to be an occupant signal 115 to read in, the recognized inmates 110 in the vehicle 100 represents. Furthermore, the device 105 adapted to a setting signal 120 for adjusting at least one characteristic of at least one landing gear setting of at least one landing gear system 125 to provide the vehicle. Here is the device 105 designed to be the setting signal 120 adapted to set a first characteristic when the occupant signal 115 only one driver 130 as a recognized occupant 110 displays. Accordingly, the device 105 designed to be the setting signal 120 adapted to set a second characteristic when the occupant signal 115 one in a rear area 135 of the vehicle 100 recognized inmates 110 in the vehicle 100 displays. According to this embodiment, the device provides 105 the adjustment signal 120 ready to set the second characteristic, since the occupant signal 115 according to this embodiment one in the rear area 135 of the vehicle 100 recognized inmates 110 in the vehicle 100 displays. To set the different characteristics, the setting signal 120 For example, transmit different control data or settings.

According to this embodiment, the suspension system 125 as a rear axle steering device 140 formed. The rear axle steering device 140 allows the rear wheels of the vehicle 100 when cornering the vehicle 100 usually in addition to driving the front wheels of the vehicle 100 , According to an alternative embodiment, the landing gear system comprises 125 additionally or alternatively a Vorderachslenkeinrichtung 145 and / or an electric stabilizer 150 , By the electric stabilizer 150 For example, a roll behavior during cornering or a pitching behavior during a braking operation of the vehicle 100 to be influenced.

The adjustment signal 120 According to one embodiment, in order to provide as the characteristic a characteristic curve and additionally or alternatively a limit value of the chassis adjustment of the chassis system 125 adjust. According to this embodiment, the device provides 105 the adjustment signal 120 ready to set as the second characteristic a second limit and additionally or alternatively a second characteristic. The second limit value is used, for example, to a maximum steering angle or a maximum steering speed of the Hinterachslenkeinrichtung 140 adjust. The second characteristic is used, for example, to a responsiveness of the Hinterachslenkeinrichtung 140 adjust.

If, according to an alternative embodiment, no occupant 110 in the rear area 135 is arranged and therefore not recognized and the occupant signal 115 therefore only the driver 130 as the detected occupant indicates, so does the device 105 according to the alternative embodiment, the setting signal 120 which is configured to set a first limit value and / or a first characteristic as the first characteristic, wherein according to this exemplary embodiment the first limit value differs from the second limit value and / or the first characteristic curve is different from the second characteristic curve. In this case, the setting signal 120 used to a range of functions of the chassis system 125 set, which is greater than the range of functions, which is set when in addition to the occupant 110 in the vehicle 100 located. For example, in the first characteristic, a larger maximum steering angle of the rear axle steering device 140 approved as the second characteristic. Also, in the first characteristic, a relationship between the steering angles of the Hinterachslenkeinrichtung 140 and the front axle steering device 145 be set differently than the second characteristic. Thus, the Hinterachslenkeinrichtung 140 For example, be more used for steering assistance, if no occupant 110 sitting in the rear area.

The device presented here 105 advantageously allows occupant-dependent use of active suspension systems 125 , Here is a location where the occupant in the vehicle 100 is detected, crucial for controlling a dependent setting the suspension system 125 , The location becomes the occupant signal according to one embodiment 115 transmitted.

Through active suspension systems 125 like the rear axle steering 140 , here in the form of an active rear-axle steering, become reactions of the vehicle 100 caused in part by inmates 110 in the rear of the vehicle 100 be perceived as unpleasant. This can lead to travel sickness, which is triggered or amplified in particular by a Momentanpolverschiebung, which by a superposition of the steering angle of Vorderachslenkung the Vorderachslenkeinrichtung 145 and rear axle steering of the rear axle steering device 140 is caused.

According to this embodiment, the device is 105 adapted to the occupant signal 115 in which the recognized inmate 110 and / or driver 130 using at least one seat contact switch 160 . 165 was detected. By using one or more signals the seat contact switch 160 . 165 , which for airbag, seat belt warnings, seat heating or the like in many vehicles 100 already exist the occupant-dependent use of the suspension systems 125 respectively.

The device 105 According to one embodiment, it is designed to optionally a situation signal 170 to receive, that is a limit situation and / or an evasive maneuver and / or a parking or Ausparkituationituation of the vehicle 100 displays. Here is the device 105 trained to adjust the adjustment signal 120 using the situation signal 170 which is adapted to set the first characteristic or a third characteristic different from the second characteristic. This setting also occurs when the occupant signal 115 indicates that the occupant 110 in the rear area 135 located. According to one embodiment, in this case by means of the adjustment signal 120 the third characteristic is set, which represents a characteristic suitable for such a border situation or danger situation and / or avoidance maneuver and / or parking or Ausparkituation and / or predetermined characteristic. According to one embodiment, using the third characteristic becomes a full functional scope of the suspension system 125 harnessed. The situation signal 170 is for example via an interface to a sensor device or a control unit of the vehicle 100 receive.

Thanks to the device 105 can therefore advantageously on the one hand the ride comfort in "normal" driving situations in which an occupant 110 in the rear area 135 On the other hand, advantages of the active suspension systems can be realized 125 be used in borderline situations or in evasive maneuvers or when parking.

Are like in 1 shown several suspension systems 125 in the vehicle 100 present, so is the device 105 optionally adapted to by means of the adjustment signal 120 a vote of the characteristics and / or characteristics to be set for the respective suspension systems 125 to effect. Such a vote is carried out according to an embodiment depending on a driving situation of the vehicle 100 , According to one embodiment depending on a vehicle speed and / or a set steering angle of the steering wheel and / or a front axle of the vehicle 100 ,

2 shows a schematic plan view of a vehicle 100 with a device 105 for preventing a passenger's travel sickness 110 of the vehicle 100 according to an embodiment. This may be the in 1 described vehicle 100 with the device 105 act.

In this embodiment, it is in 2 around the in 1 shown and described driving situation in which the occupant signal one in the rear area 135 of the vehicle 100 recognized inmates in the vehicle 100 indicates and thus of the device 105 the adjustment signal 120 is provided, which is adapted to adjust the second characteristic.

According to this embodiment, the device provides 105 the adjustment signal 120 ready, which is adapted to adjust the characteristics of the formed as a steering angle and / or a hub and / or speed suspension adjustment of the suspension system. Here, the device provides 105 according to this embodiment, the setting signal 120 ready, which is designed to set as the second characteristic, the second characteristic and / or the second limit, according to this embodiment, a limitation of an adjustable steering angle of the rear axle 200 of the vehicle 100 and / or a limitation of a speed when adjusting the steering angle of the rear axle 200 represents.

According to an alternative embodiment, the device provides 105 in a different driving situation with an occupant 110 in the rear area 135 the adjustment signal 120 prepared, which is alternatively or additionally adapted to set as the second characteristic, the second characteristic and / or the second limit, the limit of at least one adjustable stroke of at least one shock absorber of the vehicle 100 and / or represents a limitation of a speed in adjusting the shock absorber. According to the alternative embodiment, the adjustment signal 120 here to the electric stabilizer 150 provided.

The device 105 here according to this embodiment and / or according to the alternative embodiment, the setting signal 120 configured to adjust the second characteristic adapted to prevent or minimize momentum shift during a steering situation 205 of the vehicle 100 to effect. The instantaneous poles of the vehicle shown here 100 are just examples.

In 5 can be seen how it behaves in a vehicle with respect to the instantaneous pole in principle. It is a vehicle without a rear axle steering shown. The front wheels are turned to the right with a specific wheel steering angle. The chassis is usually designed so that the respective verticals of the individual wheels intersect in one point - the instantaneous pole M. Significant changes in the Momentanpols arise from slip angles, which occur at individual wheels, when the wheel or the tire no longer unrolls slipping (in extreme situations, for example, in a drift). A Momentanpolverschiebung can also occur when steering with the rear wheels, since the vertical do not cut as usual - it comes to a Momentanpolverschiebung. This shift is perceptible by the occupants, especially at the rear seats in the vehicle. Rolling and / or spring movements also have a comparatively smaller influence on the displacement of the instantaneous pole, if the respective toe angles of the wheel change as a result of these essentially vertical wheel movements.

The without the device presented here 105 possible travel sickness or the discomfort of inmates 110 may result if instead of the low current pole shift 205 a larger current pole shift would occur, as exemplified in 3 is shown (the vertical, as in 5 have been omitted, for clarity). A rather smaller current pole shift 205 results, for example, by a lower steering angle on the rear axle 200 compared to the steering angles on a front axle 210 of the vehicle 100 , In 3 on the other hand, another situation is shown in which the steering angle at the rear axle 200 is less severely limited. The rear axle steering as additional steering to increase agility or reduce the turning circle of the vehicle 100 can steer, for example, with little steering angles of a maximum of about three degrees. The Hinterachskekung can be designed as steer-by-wire steering.

3 shows a schematic plan view of a vehicle 100 with a device 105 for preventing travel sickness of an occupant of the vehicle 100 according to an embodiment. This may be the in 1 or 2 described vehicle 100 with the device 105 and act in the driving situation, with the difference that according to this embodiment no occupant in the rear area 135 is arranged.

Shown is the in 1 described alternative embodiment in which the occupant signal exclusively the driver 130 as the recognized occupant in the vehicle 100 indicates and thus of the device 105 the adjustment signal 120 is provided, which is adapted to set the first characteristic, which is different from the second characteristic.

According to this embodiment, the device provides 105 here the setting signal 120 ready, which is designed to set as the first characteristic, the first characteristic and / or the first limit, according to this embodiment, no limitation of an adjustable steering angle of the rear axle 200 of the vehicle 100 and / or not limiting a speed when adjusting the steering angle of the rear axle 200 represents. The set steering angle of the rear axle shown here 200 is thus opposite to in 2 shown steering angle of the rear axle 200 greater.

A relatively large current pole shift 205 of the vehicle 100 is allowed according to this embodiment, since it is expected that the driver 130 not sensitive to this. The instantaneous poles of the vehicle shown here 100 are placed as examples.

According to an alternative embodiment, the device provides 105 additionally or alternatively the adjustment signal 120 which is adapted to set, as the first characteristic, the first characteristic and / or the first limit which does not limit the adjustable stroke of at least one shock absorber of the vehicle 100 and / or represents no limit to speed in adjusting the shock absorber. According to the alternative embodiment, the adjustment signal 120 here additionally or alternatively to the electric stabilizer 150 provided.

4 shows a flowchart of a method 400 for preventing travel sickness of an occupant for a vehicle according to an embodiment. This may be a method that can be controlled and / or carried out by the device described in one of the preceding figures.

The procedure 400 has a step 405 of reading in and one step 410. of providing. Optionally, the method includes 400 according to this embodiment also a step 415 of receiving.

In step 405 In reading, an occupant signal representing a recognized occupant in the vehicle is read. In step 410. the provision of a setting signal for adjusting at least one characteristic of at least one suspension adjustment of at least one suspension system of the vehicle is provided. This is in the step 410. providing the setting signal that is configured to set a first characteristic when the occupant signal indicates only a driver as the recognized occupant or sets a second characteristic when the occupant signal indicates an occupant detected in a rear area of the vehicle in the vehicle. At least one further characteristic can be adjustable, for example if Although a passenger in the vehicle but no occupant sitting in the rear of the vehicle. Such a further characteristic is provided, for example, to set a functional range of the chassis system, which is located between a first feature associated with the first characteristic and a feature set associated with the second feature.

In the optional step 415 Receiving a situation signal is received, indicating a border situation such as an evasive maneuver or Ein- or Ausparkituation the vehicle. In this case, using the situation signal in step 410. providing the adjusting signal adapted to set the first characteristic or a third characteristic different from the first and second characteristics.

According to one embodiment, the situation signal is assigned a higher relevance than the occupant signal.

The steering and / or roll stabilization systems discussed herein may be implemented as an x-by-wire system (e.g., steer-by-wire). X-by-wire systems are mechanically decoupled devices in which e.g. a mechanical adjusting movement is converted into an electrical actuating signal and supplied to a control unit, which then controls the actual system component (adjusting actuator for steering or roll stabilization) purely electrically. By means of an electrical connection between the evaluation unit and the control units of the x-by-wire systems, it is therefore very easy to realize an intervention in the driving dynamics by means of the suspension adjustment by the systems shown.
