Definitions
- the invention relates to a method and a device for controlling the movement process of a hood system, in particular a hood system for a convertible vehicle.
- a system for opening and closing a Faltverdeckes or movable Fahrseugdachs in a convertible vehicle, which also has position sensors is described for example in German Patent Application DE 102 01 871 Al.
- convertible top systems Today known openable vehicle roof systems, hereinafter referred to briefly as convertible top systems, in addition to the actual top at least one controllable drive and an adjustable in position component. Depending on the response of at least one adjustable component, the top of the convertible top system is thus automatically removed from a roof area from a roof area, folds up or folds up and, for an opened state, is transported into a storage space.
- Hard shell systems typically use at least two hardshells to cover the passenger compartment.
- the associated mechanical connections, joints and drives for moving the hood system also require a relatively large storage space.
- Hydraulic coupling in particular the foremost shell, considerably reduces the number of mechanical components required.
- the convertible top system moves between a start position in which the convertible top system is fully deployed and an end position in which the convertible top system is completely accommodated in a storage space. Care must be taken that the movement is carried out in accordance with a predetermined control sequence in order to avoid damage to the individual shells by other shells or elements.
- the individual actuators To move the individual elements of the hood system, the individual actuators must therefore be activated and operated at predetermined times and in a predetermined correct sequence to each other.
- a large number of position sensors are provided which are arranged in the region of the convertible top system of a convertible motor vehicle and which are designed to determine the position of the individual elements of the convertible top system during opening and closing of the convertible top system .
- the analog position sensors may be disposed on the shells and the actuators and drive systems to determine the position of the individual elements during deployment or folding of the hood system.
- the thus determined position data of the individual shells relative to each other and to the body of the vehicle is used by a control device to process the control sequence. It is essential that the determined position data of the individual position sensors are reliable.
- position sensors Since malfunction of these position sensors can lead to damage to the convertible top system or the body of the convertible motor vehicle, a larger number of position sensors is often used, as would be at least required for determining the position.
- These redundant position sensors increase safety in determining the position when opening and closing the hood system. If, however, one or more of the position sensors fail, the safety of the position determination (despite redundancy) is no longer completely guaranteed, so that the risk of damage to the convertible top system or the body of the convertible motor vehicle when opening or closing the hood system ,
- the invention has for its object to provide an improved and in particular for a top system of a motor vehicle safer position determination.
- this object is achieved by a method having the features of patent claim 1 and / or by a device having the features of patent claim 12.
- a method for controlling the movement process of a hood system with the steps:
- a device for controlling the movement process of a hood system in particular by means of a method according to the invention, - with actuators for moving the hood system; a first plurality of position sensors configured to determine a current position of the top system, wherein the first number of position sensors is greater than a second number of position sensors required to at least determine the position of the top system; with a test device that checks whether a respective position sensor is functional and that determines a third number of functional position sensor; - With a comparison means which compares the first number with the third number; and with a control device that controls the actuators such that the convertible top system moves into a defined position, provided that the third number is smaller than the first number.
- the idea underlying the present invention is to move the top system into a defined position if one or a few position sensors are defective. Moving the hood system in this defined position can still be achieved with the help of partially redundant existing position sensors. This will damage the top by further if necessary. no longer defines controllable movements of the top or the corresponding adjustment avoided.
- position sensors all sensors can be used, which are suitable and designed, the position and location of elements of the hood system, so the top of the Drive and linkage, to determine.
- the position determination can be formed optically, acoustically, mechanically, inductively, capacitively and the like.
- the defined position designates the end position of the top system.
- the end position can designate an unfolded (hard shell roof, folding roof) or clamped (folding roof) state of the convertible top system, in which the top system is arranged above a passenger cabin.
- the end position may also designate a folded or folded state of the top system, in which the top system is housed in an at least partially closed storage space, for example in the trunk or in a specially provided for a folding or folding roof space.
- the determination of the functional position sensors is performed by comparing signals of the position sensors with data from predetermined specification tables.
- actuators for moving the top system are provided, which are operated until the top system has been moved to a predetermined, ie desired by the user target position.
- Actuators can work hydraulically, pneumatically and / or electrically. Actuators can also be motors of any kind.
- the top system remains in its current position and the actuators are not actuated when the third number is less than the second number. Since the determined third number of functional position sensors is less than the second number of position sensors required for ensuring proper functioning, the exact position of the hood system could no longer be determined in this case. The risk of damage would be too large in this case, so that then apart from a movement of the hood system. A movement does not take place even if indispensable position sensors, which are thus absolutely necessary for the position determination and which therefore can not be replaced by any existing redundant position sensors, fail. So there is no redundant replacement for these indispensable position sensors.
- the position sensors are subdivided into priority classes.
- the subdivision into priority classes takes place on the basis of the accuracy, the resolution, the quality of the measurement, the susceptibility to errors, etc. of the position sensors.
- a current position of the convertible top system is determined based on position information of a higher-priority position sensor and without taking into account corresponding position information of a lower-priority position sensor if the first position information determined by the higher-priority position sensor is different from the corresponding one determined by the lower-priority position sensor second position information.
- the position signals of the various position sensors are usually different significant or meaningful. Furthermore, the accuracy of individual position sensors can surpass the other position sensors. Therefore, it is advantageous to have this more accurate and therefore h Prioritized position sensors pay more attention.
- a mechanical model of the hood system is created. Based on the created mechanical model, the first position information is compared with the second position information using a mechanical model of the top system.
- a position sensor is determined to be functional if the position information determined by this position sensor coincides with the position information determined by the vast majority of the remaining position sensors.
- This refinement is based on the knowledge that one or more position sensors can have a defect which is not immediately apparent.
- this position sensor then generates position information deviating from the other position sensors and should advantageously not be taken into account for the position determination.
- a plausibility check of the different position information takes place among each other.
- Matching position information means that they are all to be assigned to the identical position of the hood system.
- At least one position sensor is designed to detect a distance, a change in distance, a length, a relative position, an angle, an angle change, a contact closure and / or a lock.
- Fig. 1 is a side view of a convertible vehicle with an embodiment of the device according to the invention
- Fig. 2 shows an embodiment of the method according to the invention.
- Figure 1 shows a side view of a convertible, in the trunk of a hard cover system is housed.
- the top system has a front shell 3, a middle shell 2 and a rear shell 1.
- a rear window can be integrated.
- a drive device 14 in the trunk actuates a linkage with a main four-bar linkage 11. This is connected to the middle shell 2 and connected via a pivot lever 12 with the rear shell 1.
- the middle shell 2 and the front shell 3 are connected to one another via a plurality of hydraulic actuators 13.
- the drive device 14 moves the primary linkage 11, so that the three shells 1, 2, 3 are lifted out of the boot. From a certain position of the linkage 11 and the hood system, the hydraulic actuators 13 are actuated so that the front shell 3 is pushed forward.
- a control device 10 controls the drive device 14 and the actuators 13 in accordance with a predetermined sequence or schedule. In this case, the drive must be synchronized between the various drive devices and the actuators 13 in accordance with this flowchart.
- the top system has a plurality of sensors 20-26.
- the sensors 20, 21 are arranged on the vehicle body, the sensors 22, 25 on the shells and the sensors 26 on the linkage or the drive device.
- the sensors include motion or position sensors 25, 26 which measure an angle, an angle change, a movement or a distance.
- the sensors 20, 21, 22 may be formed as contact sensors, which detect the support of the shells at certain points.
- the sensors are connected to an evaluation device 15 for transmitting the signals. The transmission can be wired or wireless. Expediently, the evaluation device 15 is integrated in the control device 10.
- the function of all of the described sensors 20-26 is to determine the position of the hood and its moving components, therefore they are also referred to as position sensors.
- the hood is moved by a drive means and one or more actuators 13 along a predetermined path, ie unfolded or folded.
- the position signals are continuously evaluated by a plurality of sensors 20-26. From the position signals, the position of the top is determined at each time. This encloses the individual position of the individual shells 1, 2, 3 with respect to the vehicle and with respect to each other.
- the sensors determine the position, angle, speed and / or contact with other components, such. B. the windscreen.
- the control commands determine for the actuators and the drive means to move them synchronously to each other.
- an emergency routine should be ensured to close the hood above the passenger compartment.
- a test device 17 S2
- An electronic failure of a sensor can be detected centrally by the control device 10 or possibly detected by the sensor itself and transmitted to the control device.
- the position signals are evaluated by an evaluation device.
- a kinematic model of the top system can be used.
- the determined position information is compared with each other (S3).
- S3 the position information is checked for plausibility. From this it can be concluded that a defective sensor is present.
- a protective function is triggered (S4). In this case, at least one defective sensor exists. If a comparator 16 determines that the number of operational sensors is above a minimum number, the top is closed, i. brought into the final position above the passenger cabin.
- the functionality of a sensor can be determined by specifications of the associated position signals or by test signals.
- the sensors and the associated position signals can also be checked for their plausibility.
- z. B. a contact sensor of the storage space report that it is closed.
- a position sensor of a shell reports that it is outside the storage space.
- Such a constellation is not possible due to the mechanical structure of the top.
- Such a contradiction can thus be determined on the basis of a mechanical model of the hood system.
- the corresponding truth table would z. B. received an entry that a contact closure of the endpoint sensor 20 is not possible at the same time closed storage space.
- individual sensors and their position signals can be assigned a higher priority.
- these priorities can be used to resolve the contradictions.
- the higher priority position signal is used to determine the position and the lower priority position signal is ignored.
