Description

Technical area

The invention relates to belt tensioner systems that can exert a tensile force on a belt applied by a driver. The invention further relates to driving experience adjusting systems by which the driver can set properties of the motor vehicle according to desired driving characteristics.

Technical background

Modern belt tensioner systems can provide that after applying the belt when starting the vehicle, a tensile force is exerted on the applied belt, so that the belt is always optimally applied to the body of the driver and thus increases safety for the driver.

From the publication DE 199 62 800 A1 a belt system for a motor vehicle is known, in which different belt tension can be exercised, in particular a comfort mode, a warning mode and a danger mode, which automatically adjust in a driving situation depending on the situation.

The publication DE 198 11 865 A1 discloses a method for controlling the operation of a pretensioner unit, additionally taking into account the data acquired by vehicle dynamics safety systems.

Furthermore, it is off DE 103 12 104 A1 a device for controlling a belt tensioner known that allows active control in a dangerous situation.

From the DE 10 2005 048991 A1 a belt tensioner system is known which indicates to the driver a corresponding setting process.

The publication DE 10 2009 049195 A1 relates to a method for a dynamic adaptation of a harness system, wherein, taking into account information about a future road course, a time for the activation is determined. The activation is made depending on a steering angle, a start-up information, a road category or a topology of road data. The brief tightening of the seat belt at the beginning of the journey does not cause a permanent increase in the tensile force on the belt, but merely serves to ensure an optimal fit of the belt. However, this does not mean that a driver is held more reliably in a sportier driving style in the seat, feels more tied to the vehicle and feels better integrated into the vehicle and occupies an optimized for vehicle control seating position.

In addition, if necessary, an automatically varying belt pretension can be perceived as disturbing if it apparently changes the pretensioning of the belt during a drive.

It is an object of the present invention to provide an improved belt tensioner system in which a driver can be better kept in the seat in a sportier driving style and perceives a sense of extra safety and vehicle control. Furthermore, it is an object of the present invention, existing Fahrlebniseinstellsysteme that previously only affect the driving dynamics of a vehicle to expand ergonomic aspects.

One idea of the above driving experience adjustment system is to apply a variable belt tensioning force to the applied belt, which can be selected via an operating element by the driver or another user and is thus adjustable. As a result, for a sportier driving the user can increase the contact pressure on the vehicle seat.

Furthermore, the operating element may comprise at least one element comprising a control knob, an operating switch, a menu-guided operation with separate input and display elements and a touch-screen input.

There may be a driver position adjustment system with one or more vehicle seats and / or with a steering wheel, wherein a seat surface and / or a backrest and / or one or more side cheeks of the seat surface and / or the backrest and / or a seat surface extension of the one or more Vehicle seats and / or a steering wheel in certain positions and / or positions are adjustable, wherein the control unit is configured to adjust the positions and positions of the one or more vehicle seats and / or the steering wheel and the biasing force of the belt tensioning device together depending on the selection made

Thus, the control element can simultaneously provide an adjustment of the driver's seat and the steering wheel and thereby a change in the driver's seat position. As a result, by adjusting the operating element once, both the belt tensioning force and the seating position can be adjusted so that it is possible for the driver or another user to adjust the grip in the vehicle seat and the operating options of the steering wheel according to a sportier or more comfortable driving style. In particular, it is advantageous that the driver does not have to select a sportier or more comfortable seat, seat position and safety belt separately each time the driving mode is changed, as a result of which the operating effort is significantly reduced.

By coupling the increase of the belt tensioning force and / or the seat position to the selection of sportier driving characteristics of the motor vehicle, the safety of the driver, who has a much better grip in the seat due to the tight-fitting seat belt, increases. The reduced slack reduces in the event of an accident, the slipping motion of the driver's body in the seat belt and thus actively protects the driver.

In particular, the operating element may be a driving experience switch with which, according to a preselection of the driver, a desired driving dynamics, i. an expression of driving dynamics relevant components of the motor vehicle can be adjusted. In particular, by means of the driving experience switch, the landing gear, i. the suspension characteristics and / or the damping characteristics of the vehicle, the engine response, in vehicles with automated transmissions, the gear shift behavior, the steering behavior of the steering and the engagement behavior of the vehicle stabilization systems are set to a sportier or more comfortable driving. In this way, the driver can simultaneously make several settings in the motor vehicle by operating the driving experience switch so that one or a more comfortable driving is supported.

In particular, the coupling of the belt tension to the driving experience switch has the advantage that the driver receives a direct haptic feedback to the selected driving mode when selecting a sportier driving mode on the firmer belt and / or the adjusted seating position. Further, the belt tension coupled to a drive mode and the seat positions enhance driver's driving feeling and driving feeling. So he can learn, for example, by a firmer pretensioned seat belt and a more upright and closer to the steering wheel seat closer engagement with the vehicle, as the body is better supported in dynamic cornering by seat and belt and fixed in a more favorable for vehicle control seating position.

According to one embodiment, the at least one vehicle system may include a suspension adjusting system, via which a suspension and / or damping behavior of the chassis is adjustable, and / or a motor control, with which an engine response to a change of an accelerator pedal position is adjustable, and / or a transmission control, with a transmission shift behavior can be adjusted in automated transmissions, and / or a steering system with which a steering behavior of the steering is adjustable, and / or a vehicle stabilization system, with which the intervention thresholds for vehicle stabilization are adjustable include.
