Description

  • The present invention relates to an assistance system of a vehicle, which is preferably a novice driver or learner served.
  • The invention also relates to a Support procedures a driver, preferably a novice driver or learner driver, who operates a vehicle.
  • More and more motor vehicles show Systems for observation of the closer and further surroundings of the vehicle. In particular, are increasing Dimensions systems used for the detection of objects or other road users, that are in the lane of your own vehicle. in this connection the distance to the object or vehicle is recorded and evaluated.
  • From the DE 44 37 365 A1 A method is known in which the driver is informed of a potentially dangerous situation on the basis of the evaluation. Taking into account the distance, a “hazard potential” is determined as a measure of the dangerousness of the driving situation or the hazard and is visually communicated to the driver on a display device.
  • The invention is based on the object To create assistance system of a vehicle, preferably a driver novice drivers or learner driver, supported in an assessment to learn the current traffic situation.
  • This object is achieved according to the invention the characteristics of the independent claims solved. Due to the characteristics of the dependent subclaims advantageous developments specified.
  • According to the invention the task solved by an assistance system of a vehicle, which a vehicle driver, preferably Novice driver or a learner driver, operates which assistance system has at least one means of recording the speed of the vehicle, at least one means of detection a front obstacle and / or front vehicle, at least one Means for detecting the distance of the vehicle from the front obstacle and / or the front vehicle and at least one means of transmission at least one driving school-specific information to the driver, preferably Learner the driver, preferably learner drivers, in the assessment the hazard potential of the current driving situation in view supported on the front obstacle and / or front vehicle.
  • The term "frontal obstacle" here means one obstacle in the traffic area in front of the vehicle. The The term is to be interpreted very broadly. It includes everyone in the traffic area objects, such as other road users (Vehicles, cyclists or pedestrians). The term "front vehicle" in the sense of Invention meant a vehicle in front. The term "novice driver" is to be interpreted very broadly. He means a driver the relatively poor driving experience or ability to lead of a vehicle. Likewise, people fall under the term that when running a Vehicle - longer Have practical driving uncertainties or are anxious or general People who are leading a vehicle a presentation of driving school-specific information to wish or need.
  • As a means of measuring speed, to determine a front obstacle and / or front vehicle and for detecting the distance from the front obstacle and / or the All known and conceivable sensors come into consideration in the front vehicle. Preferably, however, a radar system is used with which the distance of the own vehicle to the vehicle in front and the relative speed of the two vehicles can be determined to each other.
  • The determined by the sensors Measured values are processed by a computer or microprocessor. The measurement data of the sensor and the values derived from it are included in the different driving school specific formulas and compared with one System to the driver, preferably novice drivers or learner driver, especially for learning how to assess the hazard potential suitable is.
  • The assistance system is preferred for a Driving school vehicle provided that a learner driver under the supervision of a driving instructor and / or a driving examiner served.
  • According to the invention, that the assistance system has at least one means of transmission at least one driving school specific information about the Distance of the vehicle from the front obstacle and / or front vehicle to the driver, preferably novice drivers or learner driver, having. With the system according to the invention, the vehicle driver can, preferably novice drivers or learner driver, in the practical implementation of theoretical considerations regarding a safety distance supports become.
  • This driving school-specific information can enable the vehicle driver, preferably novice drivers or learner drivers, to assess the potential hazard based on the distance from the front obstacle and / or front vehicle. This greatly improves the feeling of the vehicle driver, preferably the novice driver or learner driver, for the correct distance. There are also advantages for the driving instructor for driving school instruction. Because he is actively supported in his practical teaching. In practical training, he is no longer forced to take the Ab stood to estimate the front vehicle itself. In addition, there is no problem that the learner driver also trusts an estimated driving instructor. A displayed distance value based on measured values is generally accepted as "correct" by a learner driver.
  • According to the invention, it is provided that Vehicle at least one means for determining the relative speed of the vehicle to the front obstacle and / or front vehicle (i.e. related to the front obstacle and / or front vehicle) and that the assistance system has at least one means of transmission at least one driving school specific information about the Relative speed to the front obstacle and / or front vehicle the driver, preferably novice drivers or Learner having. This driving school-specific information should preferably be given to the vehicle driver novice drivers or learner driver, an assessment the hazard potential by own evaluation of the relative speed enable related to the front obstacle and / or front vehicle.
  • [15] According to the invention provided that the vehicle has at least one means of evaluation the distance of the vehicle from the front obstacle and / or front vehicle dependent on from the determined relative speed to the front obstacle and / or front vehicle and that the assistance system at least a means of transmission at least one driving school specific information about the Assessment of the distance depending from the relative speed to the vehicle driver, preferably novice driver or Learner having. This allows the driver, preferably novice drivers or Learner his own assessment of the relative speed to the front obstacle and / or compare the front vehicle with the value displayed by the system, for his assessment to improve.
  • According to the invention, it is provided that Assistance system at least one means of transmitting at least one has further driving school-specific information selected from the group:
    • - stopping distance, e.g. as an absolute indication of the due to the vehicle speed determined distance in meters,
    • - Risk of impact on the front obstacle and / or front vehicle, e.g. in form of a relative impact risk (%),
    • - Estimated impact speed on the front obstacle or front vehicle based on an estimate Based on average novice driver response time or learner and in the event of the front vehicle braking hard,
    • - criminal liability due to an insufficient distance from the front vehicle, e.g. by Disclosure due to an insufficient safety margin
    • - covered Distance in meters per second (m / sec) due to current vehicle speed,
    • - Influence the visibility the driver on the response time or the braking distance, especially extension of the total braking distance in the event of a longer reaction time due to lack of visibility, such as. in rain, snow, fog or at dusk or night,
    • - Influence additional Parameters such as road condition, brake system status and / or status the vehicle tires, on the braking distance, in particular an extension the braking distance in the event of reduced static friction between the road and tires, such as in the rain, snow-covered road or icy conditions or due to insufficient tire pressure, and
    • - Rating the risk of impact in the event of the driver braking his own vehicle, in the event of a dodge of your own vehicle by operating a steering wheel and in the case of a combination of full braking and simultaneous Dodge.
  • In particular, the vehicle driver should prefer here novice drivers or learner driver, an aid to learning the effects of additional conditions, such as bad ones Visibility or bad road conditions, be presented on the hazard potential and it should preferably the driver novice drivers or learner driver, the relevant physical laws in road traffic be made clear so that he is able to meet his Adjust the distance to the front obstacle and / or front vehicle accordingly.
  • According to the invention, it is provided that the at least one means of transmitting at least one driving school-specific information at least one visual display having. Preferably at least one means is provided with which the distance, the relative speed and a minimum distance (Safety distance) is displayed visually.
  • According to the invention, it is provided that the optical display is provided for a color representation of at least one driving school-specific information item, the color being changed in color in accordance with the hazard potential. In this way, the visual representation of the distance, the relative speed and / or the minimum distance (safety distance) is preferably changed in accordance with the hazard potential. For example, a color is selected as the basic color that signals correct behavior to the novice driver or learner driver, such as a green hue. If a distance and a relative speed fall below a first limit value, a second color, for example a yellow hue, is selected which has a "medium" Represents potential danger. For the vehicle driver, preferably novice driver or learner driver, this situation means that he is asked to maintain a sufficient safety distance. If he does not comply with this and the appropriate safety distance is clearly undershot, then the vehicle driver, preferably novice driver or learner driver, is made aware of a high risk potential by means of a "signal color", such as a red color.
  • It is provided that by means of a Control element individual driving school-specific information for display on the visual display from the vehicle driver, preferably novice driver or Learner are available. Accordingly, not all information is available at the same time shown on the display, but they can be called up one after the other.
  • According to the invention, it is provided that at least one additional optical and / or acoustic means is provided for the purpose of warning the Driver, preferably novice driver or Learner, if the vehicle has a critical threshold, especially one Safety distance from a front obstacle and / or front vehicle, below.
  • According to the invention, that the at least one means of transmitting at least one driving school-specific information at least one acoustic means for the transmission of information having. The information is preferably linguistic Comments and / or instructions submitted.
  • Through a voice output of the driving school specific Information is achieved that the driver, preferably novice driver or Learner is less distracted from traffic. In practical Driving school education or a learning phase for driving a vehicle is the novice drivers or learner driver already so strong with observing the surrounding traffic, the steering and actuation the brake and accelerator pedals as well as other activities such as coupling and Switching, busy, that attention to a visual display distracts him greatly. acoustic Information is better and safer to perceive in such Situations.
  • The underlying task is also by a method for assisting a vehicle driver, preferably novice driver or learner driver, solved, which method records the speed of the vehicle, a front obstacle and / or a front vehicle is determined and the Distance of the vehicle from the front obstacle and / or the front vehicle is detected, and in which the driver, preferably novice driver or Learner Driving school-specific information is presented to the danger the current driving situation with regard to the front obstacle and / or estimate front vehicle can.
  • The method is used in particular support of a learner driver used under the supervision of a driving instructor and / or a driving examiner Vehicle operated to improve learning a safe driving style.
  • In the method according to the invention the driving school specific information is preferably on acoustic way of spoken comments or instructions presented.
  • According to the invention, that the transmission the driver-specific information to the driver, preferably novice drivers or learner driver, are presented as part of a learning program. The tutorial serves to learn to lead of a vehicle, in particular for learning a traffic situation adjusted distance to the front obstacle and / or front vehicle.
  • The transmission of driving school-specific information is in view of a reaction of the driver, preferably novice driver or learner driver the respective traffic situation, especially with regard to a Brake and accelerator pedal actuation and steering if necessary, customized. For example, in a "stressful situation" for the vehicle driver, it is preferred Novice driver or Learner very little, essential or no information or instructions taught. Is the driver preferably novice drivers or learner driver, on the other hand, less strongly due to the current traffic situation encumbered, e.g. when driving straight ahead with relative steady speed, then can advantageous to him Information and tips are conveyed. It is also intended that the tutorial or its flow by manual entry the driver, preferably novice driver or learner driver, or another person, such as a driving instructor who can be influenced or is adjustable.
  • The underlying task is also by a method for learning to drive a vehicle, in particular for one Novice driver or Learner solved, which method values for determined at least one dynamic variable be the movement of the vehicle as a whole and / or Describes object in a traffic situation, and being based a leader of the determined values information or instructions are presented to the vehicle learning to lead support a vehicle or enable.
  • The learning process gives a vehicle driver, preferably a novice driver or learner driver, optically and / or acoustically, preferably at least verbally, according to a specific learning program, the information or instructions that lead to an improvement in his assessment of the traffic situation, so that the driver driver, preferably novice drivers or learner drivers who can adapt to the situation and react appropriately. It can also be used to convey relationships between various factors influencing the risk of an accident. This is how he learns to correctly assess the driving and traffic situation.
  • As a dynamic variable, at least are preferred taking into account the sizes those already based on existing sensors and control and regulation systems is present in a vehicle. In particular, come through brake control systems, e.g. ABS, ASR or ESP systems, determined variables, such as vehicle speed, Vehicle acceleration, vehicle deceleration and vehicle lateral acceleration into consideration. In addition, other Sizes like Brake and traction slip and road condition variables (e.g. Stiction) become. Weather conditions already determined by existing systems, like rain, snow or fog, and vehicle conditions like Tire pressures, tire wear or brake wear can be considered. In addition, in modern vehicles, sizes of vehicle drive, such as Engine speed, accelerator pedal position and engine drag torque, and if necessary the steering wheel actuation, like a steering wheel rotation angle. These are also preferred Sizes by takes into account the tutorial. Especially the learning program is preferably used in the vehicles, the one above a system for determining the distance to a front obstacle or have front vehicle. Because in this case, Tutorial to maintain an appropriate safety distance objects to be learned.
  • The invention is described in the following description with reference to the attached figures ( 1 to 3 ) explained in more detail by way of example.
  • The 1 schematically shows an embodiment of the assistance system.
  • In the 2 One embodiment of a display for the assistance system is shown schematically.
  • In the 3 is a way of displaying driving school-specific information is shown schematically on a display.
  • In the 1 the assistance system and its integration into the vehicle electronics is shown schematically.
  • From the data of an ABS or ESP control unit 1 of the vehicle are via a vehicle bus system, such as CAN bus 2 , the wheel speeds as an input signal 3 an evaluation and control unit 4 of the assistance system. From the input signal 3 the vehicle's own speed is determined. As an alternative or in addition, a self-speed (vehicle reference speed of the brake control) of the evaluation and control unit that has already been determined by the ABS or ESP control unit can also be used 4 be transmitted.
  • A distance or distance sensor 5 provides a current distance signal 6 , which indicates the distance to a preceding object, in particular a front vehicle. This will be the evaluation and control unit 4 also via the vehicle bus system 2 transmitted. On the basis of the vehicle's own speed and its distance and changes in distance to the object in front as input signals, the relative speed between the vehicle and the object is determined using the evaluation and control unit 4 determined. The measurement data and the values determined or derived from them are converted into representable signals for display 7 , preferably a color display.
  • By means of the evaluation and control unit 4 Driving school-specific information is obtained from the current measurement data, which allows an assessment of the danger of the current driving situation (danger potential) with regard to the front obstacle and / or front vehicle, and this information is made available to the learner driver via the display 7 transmitted. In particular, it is provided that the display enables a comparison of the current distance with different rule of thumb from driving school theory.
  • 2 schematically shows an embodiment of a display for the assistance system. The ad 10 has a color display here 11 for the visual representation of information for the driver, preferably learner drivers. There are also control units 12 . 13 arranged. Here is a control for turning the display on and off 12 and an operating element for selecting the desired information 13 intended. The system can be switched on and off at the push of a button. The display variants can be selected using a selection button 13 can be called up one after the other.
  • In the 3 are different options ( 3a to 3e ) to display driving school-specific information on a display, for example that in 2 shown color display 11 , shown.
  • It is envisaged that at least the distance from the front obstacle or front vehicle ( 3a ) can be called up on the display or is always displayed. The distance display enables the driver, preferably the learner driver, to drive at a safe distance. The current distance and a determined minimum distance or safety distance can also be displayed simultaneously or alternatively. In this way, the vehicle driver, preferably the learner driver, can learn to keep the safety distance at different speeds over longer distances. In doing so, he gets a better feeling for the correct distances at different speeds. By driving hours during driver's license training, the system therefore learns a feeling for the safety distance, which means that road traffic hazards are better assessed and the risk potential is reduced.
  • It is envisaged that the relative speed, i.e. the speed difference between the front obstacle or front vehicle and vehicle ( 3b ) can be called up on the display or is always displayed. By ascertaining and clarifying the relative speed, the vehicle driver, preferably the learner driver, is shown that at a relative speed of, for example, 50 km / h, a possible impact on the vehicle in front corresponds to an impact on a stationary vehicle at a speed of 50 km / h. Furthermore, the vehicle driver, preferably the learner driver, is enabled to maintain a constant relative speed of approximately 0 km / h. It is therefore possible to learn how to drive smoothly, adapted to the vehicle in front.
  • It is envisaged that the stopping distance ( 3c ) can be called up on the display or is always displayed. In order to clarify the relationships between the stopping distance at different speeds and the respective distance from the vehicle in front, the driver, preferably the learner driver, is given a display in practice. According to an approximation [v / 10 ∙ 3 + (v / 10) Z], the stopping distance is approx. 130 m at a vehicle speed of 100 km / h. This shows that higher vehicle speeds result in a large increase in stopping distance. The driver can be taught the effects of excessive vehicle speed.
  • It is envisaged that the risk of impact ( 3d ) can be called up on the display or is always displayed.
  • In addition, it is also possible to display information on the extent to which the current distance represents an administrative offense or a criminal offense and how high the amount of a fine would be ( 3e ). For example, with a vehicle speed of 100 km / h and a distance to the vehicle in front of less than 25 m (rule of thumb speedometer / 4 in m), a police distance measurement would impose fines and an entry in the traffic central register in Flensburg would be the consequence. If a situation arises in the driving lesson, in which the current distance in the event of a police check would result in a punishment, the vehicle driver, preferably the learner driver, can be expressly warned by the driving instructor and advised of the misconduct, e.g. by a "charge warning lamp" that Such an event indicates that the time period, how long the distance is so small that an administrative offense or criminal offense is given, is taken into account, because at the moment the limit is only considered to fall below the limit values for 2 to 3 seconds recognized and prosecuted by the police, so that the driving instructor can have a positive impact on the driver's traffic education.
  • It is envisaged that a fictitious reaction path of the driver, preferably the learner the display is available or is always displayed. By comparison with the reaction path in practical driving training is the learner illustrates how long reaction paths can be. The distance often seems according to the driver's judgment, to be sufficient and harmless, the comparison with the reaction path shows how risky a small one is Distance to the person in front can be. For example, at 100 km / h the reaction path 30 m. As the reality in road traffic often shows the reaction path underestimated by many drivers.
  • Extensions to the display with additional information are possible, in particular a comparison of the current distance to the safety distance, a comparison of the current distance to the stopping distance, a comparison the current distance to the reaction path and a comparison of the speeds of the own vehicle with the speed of a front vehicle is advantageously possible here.
  • The information mentioned represents snapshots of a driving situation of the vehicle. They are preferably on a round or linear scale, here by means of an approximately horizontal, analog scale 20 shown. Several of these representations can be on the display at the same time 11 respectively. But it can also only be one scale at a time 20 are shown, their scaling 21 . 22 . 23 . 24 . 25 , then changes according to the information retrieved.
  • The current value of the information retrieved is preferably displayed using a bar 28 . 29 . 30 . 31 . 32 . 33 on the scale 20 indicated and can by symbols, such as a schematic representation of two vehicles 26 . 27 advantageous to be clarified visually. So that the information can be clearly assigned, the respective information displayed can also be written 33 . 34 . 35 . 36 . 37 to be discribed.
  • A significant improvement with regard to estimating and learning the danger of current driving situations for the learner driver is through their visualization by changing the color of the bar display 28 . 29 . 30 . 31 . 32 reached. For example, the bar color changes from "green" to "yellow" or "red". If certain safety-relevant threshold values are exceeded, the vehicle driver, preferably a learner driver, can additionally receive additional visual warnings, such as flashing of text fields and / or symbols or additional text fields , for example with a lettering "Caution !!!" 38 , and / or symbols are pointed out. In addition, acoustic signals enable a further warning. When falling below At a certain distance (eg threshold "reaction path"), an acoustic warning signal can sound, for example. If the driver, preferably the learner driver, maintains the distance for a defined time, the frequency of the warning tones increases, for example.
  • example
  • A learner driver approaches a vehicle in front at a speed of 100 km / h. The distance sensor detects the vehicle in front. For example, the distance when detected by the sensor is 100 m. the display 10 shows the current distance of 100 m by a green bar 28 between those in front 27 and own vehicle 26 on. The learner further approaches the vehicle in front. The bar 28 shrinking. If the distance falls below 50 m (safety distance at 100 km / h according to the formula speedometer / 2 in m), the bar will color 28 yellow on. Above the bar 28 a red text field appears with the yellow blinking inscription "Caution !!!" (cf. e.g. 3d ). In addition, an acoustic signal sounds once, which warns the learner driver (and driving instructor). If the learner approaches the vehicle in front, the bar changes color 28 if the distance is less than 30 m (reaction path at 100 km / h according to formula V / 10 ∙ 3) red on (cf. 3a ). In addition, the red text field now shows a flashing yellow lettering "Too late !!!" and an acoustic signal sounds repeatedly. The learner driver (and driving instructor) is warned. The distance to the front vehicle is less than the reaction path at the appropriate speed the great danger that if the front vehicle brakes fully, it will hit this vehicle. The other displays ( 3b to 3e ) work in a similar way with a color change of the display bar 29 . 30 . 31 . 32 , The color changes of the bars are essential 28 . 29 . 30 . 31 . 32 and an additional visual and / or acoustic warning when there is a high risk potential.
