Description

Technical Field

[0001] The invention relates to a system for improving driving safety when driving a two-wheeled motor vehicle and a method for improving driving safety when driving a two-wheeled motor vehicle. Background Art

[0002] In two-wheeled motor vehicles, such as motorcycles, the driver's posture or sitting position occupies an important position. Motorcycle drivers are often prone to driving with a wrong body posture, especially when turning. This can lead to an unfavorable center of gravity distribution and limited maneuverability of the motorcycle. Finally, the wrong driver posture / sitting position leads to a high safety risk. DE 10 2017 200065 A1 discloses a steering assistance method in a two-wheeled vehicle when turning, wherein the steering system of the two-wheeled vehicle is equipped with a servo unit for generating a steering assistance servo torque, wherein the current speed and the current tilt position are determined by a sensor mechanism in the two-wheeled vehicle and the position of the two-wheeled vehicle is determined by a position determination system, and when the current tilt position deviates from the target tilt position corresponding to the curve radius and the current speed, a servo torque is generated in the steering system by the servo unit, and the servo torque is oriented in the opposite direction to the deviation of the current tilt position from the target tilt position. However, this steering intervention may be quite uncomfortable for unskilled motorcycle drivers. DE 10 2019 202 330 A1 relates to a method for determining the position of a motorcycle driver on a vehicle, in which method a sensor signal related to a person is determined by means of at least one person sensor worn by the motorcycle driver and a sensor signal related to the vehicle is determined by means of at least one vehicle sensor arranged on the vehicle, wherein the position of the motorcycle driver on the vehicle is determined based on the sensor signals related to the person and related to the vehicle. Thus, for example, a characteristic curve in an assembly that influences the driving dynamics of the vehicle can be set based on the position of the motorcycle driver. In addition, the motorcycle driver can be warned when his seated position deviates from a target position. The disadvantage is that a critical situation has also occurred. Summary of the invention

[0003] The object of the present invention is therefore to provide a system for increasing driving safety when driving a two-wheeled motor vehicle and a method for increasing driving safety when driving a two-wheeled motor vehicle, wherein the known systems and methods can be expanded and adapted.

[0004] This object is achieved by a system according to claim 1 and by a method according to claim 8. Further advantages and features are revealed in the dependent claims as well as in the description and the drawings.

[0005] According to the present invention, a system for improving driving safety when driving a two-wheeled motor vehicle comprises a detection device, which is designed to detect the actual driver posture and vehicle information and environmental information, wherein the detection device is designed to derive a target driver posture from the vehicle information and environmental information and according to one embodiment from the actual driver posture and display it to the driver. Therefore, it is advantageous to provide a system at present, which allows the optimization of the seating position or the driver posture. Therefore, the system helps to improve the driving skills of the driver. Therefore, dangerous situations can be advantageously avoided or, in an ideal case, dangerous situations do not occur at all. The detection device advantageously allows recording or detecting actual conditions. The actual conditions here include the actual driver posture and vehicle information and environmental information according to one embodiment. In other words, what the vehicle is doing, what the driver is doing, or what the surrounding or environmental situation is.

[0006] According to one embodiment, the detection device is also designed to detect and / or analyze the driver's state, in particular, for example, to detect whether the driver is fit to drive or too tired, inattentive or even unconscious, etc. It is also possible to detect whether the driver is sitting on the motorcycle, whether the motorcycle is lying on the ground, and in particular, whether an accident has occurred or is at least about to occur. In these cases, the system is preferably designed to issue an emergency call or put the vehicle into a safe driving state, in particular automatically or autonomously and, for example, via an IT system (in combination with a mobile terminal device, such as a smartphone, a corresponding application, etc.).

[0007] According to one embodiment, the actual driver posture includes at least one of the following information: head posture, upper body posture, arm posture, shoulder posture, leg posture, sitting position on the driver's seat (eg, front, back, middle), etc.

[0008] According to one specific embodiment, the vehicle information includes at least one of the following information: the tilt angle of the two-wheeled vehicle, the steering wheel position, the speed, the center of gravity (with and without the driver and optionally a passenger), the accelerator pedal position and / or the brake lever / brake pedal position.

[0009] According to one embodiment, the environmental information includes at least one of the following information: route direction, route overview, driving route / ideal route, weather, road conditions and / or hazard notification.

[0010] The system can be used to determine, for example, the driver posture that is optimal for the ideal route. According to one specific embodiment, the system is designed to display to the driver the optimal target driver posture for reaching or following the ideal route.

[0011] In particular, when turning, there is the possibility, for example, of leaning into the bend. This means that the driver and the two-wheeled vehicle have essentially the same inclination angle relative to the driving plane. In addition, the driver can be suspended into the bend, wherein the driver has a significantly smaller inclination angle relative to the driving plane than the two-wheeled vehicle. Alternatively, it can be a so-called "pushing", wherein the two-wheeled vehicle has a smaller inclination angle relative to the driving plane than the driver. Depending on the situation, the system can expediently provide an ideal target driver posture at the moment.

[0012] Furthermore, as an alternative, specific boundary conditions can be predetermined in order to influence the target driver posture within a certain range. Thus, in the case of so-called "super sportsters" they are usually not "pushed". Instead, in the case of this type of machine, the driver is more likely to lean into the bend or hang in the air. Suitably, the system can take different nuances into account.

[0013] Preferably, the system comprises a display which is designed to display one or more instructions for achieving a target driver posture to the driver. Thus, for example, the display can be used to indicate to the driver that he must lean further into a bend. Likewise, for example, it can be indicated to the driver that he must push the two-wheeled vehicle further into a bend. Furthermore, for example, a signal can be given to the driver that he is sitting too far forward, etc.

[0014] Therefore, the system can advantageously improve driving skills.Ideally, the deviation between the actual driver posture and the target driver posture becomes smaller and smaller over time.

[0015] According to one embodiment, the detection device comprises one or more detection devices. Such detection devices may include sensors, such as image sensors, pressure sensors, tilt sensors, etc., which are designed to detect, in particular, actual driver posture, vehicle information, and environmental information. In particular, sensors and data already present in the vehicle's electronic equipment may also be used to detect vehicle information.

[0016] According to one embodiment, the system comprises a database, wherein the database comprises additional information for influencing the target driver's posture. Such additional information may be, for example, the above-mentioned type of motorcycle, i.e., information relating to, for example, a touring motorcycle, a sports motorcycle or a moped. The additional information may also be historical data including the driver's driving style. Furthermore, driver data such as gender, height, weight, etc. may also be included.

[0017] The invention also relates to a method for improving driving safety when driving a two-wheeled motor vehicle, the method comprising the following steps:

[0018] - Detect actual driver posture;

[0019] - Analyze vehicle information and environmental information;

[0020] - deriving a target driver posture from vehicle information and environment information and, according to one embodiment, from an actual driver posture;

[0021] - Display target driver posture to the driver.

[0022] The method can advantageously enable the driver to assume an optimal driving position on a two-wheeled motor vehicle. The driver is assisted in driving. For example, the system or method assists the driver in driving an ideal curve line and ensures safe operation of the vehicle during acceleration and deceleration. The analysis / assistance for the optimal driver position / driver posture including head posture can be combined with an analysis and suggestions for driving on straight roads and in curves based on the ideal curve line. The ideal curve line can be created with the help of a simple model based on the curve length / curve angle or can be enriched with the help of a lane camera and a detailed environment model.

[0023] Preferably, the method comprises the following steps:

[0024] - Boundary conditions are predefined for influencing the target driver posture. In this method, the driver's training level, whether he likes to drive fast or slow, etc. can be advantageously taken into account. For example, a track mode can be set for safe sections. In this case, driving as fast as possible with a corresponding driver posture is a possible target variable. According to one embodiment, the speed adjustment (to be increased or decreased) and the target driver posture can also be displayed to the driver.

[0025] According to one embodiment, the method comprises the following steps:

[0026] - Record actual driver posture.

[0027] Suitably, recording the actual driver's posture allows for later analysis and evaluation. Thus, for example, the actual driver's posture can be compared with the target driver's posture afterwards. The driver can draw possible conclusions therefrom and can further improve his driving style.

[0028] The advantages and features mentioned in conjunction with the method also apply correspondingly to the system and vice versa. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Additional advantages and features are derived from the following description of embodiments of the system or method with reference to the accompanying drawings. The accompanying drawings are as follows:

[0030] Figure 1 A schematic diagram showing a two-wheeled motor vehicle with a driver is provided to illustrate the working method of one embodiment of the system or method;

[0031] Figure 2 A flow chart is shown to illustrate the mode of operation of one specific embodiment of the system or method. DETAILED DESCRIPTION

[0032] Figure 1 A driver 1 driving on a two-wheeled motor vehicle 2 is shown. The two-wheeled motor vehicle 2 includes a system for improving driving safety. The system includes a detection device, which is currently indicated by reference numeral 70. The detection device 70 includes a plurality of detection devices 72, such as sensors. Some detection devices 72 are oriented toward the driver 1 to detect the actual driver posture 10. It is also shown that at least one detection device 72 is oriented forward along the driving direction of the two-wheeled motor vehicle 2 to detect, for example, environmental information 30, such as the direction of the route, etc. Reference numeral 20 indicates and represents vehicle information, such as tilt angle, speed, current center of gravity position, presence or absence of driver 1, etc., which is detected by vehicle electronics. The system works, for example, so that a target driver posture 40 can be calculated or derived from the vehicle information 20 and the environmental information 30 and the optional actual driver posture 10. Suitably, the target driver posture is displayed to the driver 1, wherein a display 60 is currently provided for this purpose. Therefore, the driver 1 is informed by the display 60 how he must adjust his body posture in order to achieve, for example, an ideal line of a curve. According to one embodiment, at least one camera analyzes the driver 1 and his body posture or head posture. Another sensor analyzes, for example, the sitting position of the driver 1 on the seat, the center of gravity (of a motorcycle with a driver). The optional lane camera recognizes the road, for example. According to one embodiment, the system includes a road and curve model, which is designed to calculate the ideal line of the curve. The driver's posture / driver position is compared and analyzed with the road curve model. Through the display 60, the driver 1 continuously or also after driving obtains suggestions for improving his driver's posture / driver position. Suitably, the system is also designed to communicate with a mobile terminal device, such as a smartphone, and transmit data accordingly. According to one embodiment, communication with a networked (IT) system can be achieved via a smartphone. Therefore, it is suitable to detect the driver's state, the presence of an accident, and to issue an emergency call.

[0033] Figure 2The flow of the method is schematically shown, wherein it is particularly clear that the method is an iterative process. In the detection device 70, a target driver posture 40 is calculated from the actual driver posture 10, the vehicle information 20 and the environmental information 30. The target driver posture can be informed to the driver 1 by the display 60, and then the driver can correct his actual driver posture 10 if necessary. The actual driver posture will be detected again, etc. A new target driver posture 40 is calculated from the vehicle information 20 and the environmental information 30 that change during this period. Reference numeral 50 indicates that the detection device 70 can be parameterized with corresponding boundary conditions or take these boundary conditions into account. In this case, for example, it can be predetermined which type of motorcycle is involved, whether it is a primary driver or a senior driver, etc.
