Definitions
- the invention relates to a distance measuring device for motor vehicles, in the further course also abbreviated to motor vehicles, in particular vans and combination cars (station wagons), in which a tailgate in the open state protrudes beyond the rear end of the vehicle.
- Such devices may include the literature, such as "safety and comfort systems” (ed. Robert Bosch GmbH, 3rd edition, 2004, Vieweg Verlag Wiesbaden) are ent ⁇ taken.
- the aforementioned source describes, in particular on pages 276 to 279, the operation of a corresponding Einpark ⁇ help.
- sensors are arranged in the respective bumper of the vehicle, through which ultrasound waves are usually emitted.
- the distance between the sensor and the obstacle is then determined via the so-called echo transit time method.
- the determined distance is displayed to the driver of the car by means of an acoustic and / or optical signal.
- the acoustic signal is usually a sound output at variable intervals; the optical signal is usually transmitted by LEDs or by means of a display to the driver.
- the devices described here are disadvantageously only able to accurately detect the distance between the respective bumper, which forms the front or rear end of the vehicle in the regular driving operation of the vehicle, and a possible obstacle.
- the vehicle may be in a situation in which a tailgate or a corresponding rear door, for example, during a maneuvering, is open and thus change the outer dimensions of the vehicle.
- the obstacle detection is carried out by means of at least one sensor which is connected to a control unit.
- the control unit is further connected to a drive element, which performs the opening operation of the door assembly.
- Another use of a distance measuring device describes DE 198 29 731 AI.
- the system described therein provides, in a tailgate of a vehicle, means for detecting objects during the opening and optionally the closing operation of the tailgate.
- the range of movement of the tailgate is scanned and issued upon detection of an obstacle, a warning signal or interrupted the pivoting operation by an opening brake.
- the distance measuring device is used to control opening and closing operations of vehicle doors or flaps.
- the immediate pivoting range of the vehicle door or the vehicle flap is monitored by means of the distance measuring devices.
- the sensor used in each case is connected to a control unit, which further controls, for example, a drive element of the respective vehicle door or flap.
- a monitoring of the distance between an open, rear door or flap of a moving vehicle and an obstacle, for example during a shunting or parking operation, is not possible with the above-mentioned systems.
- a distance measuring apparatus comprises Minim ⁇ least a distance detecting means for detecting a Abstan of between the motor vehicle and which are being its potential range of movement obstacle on.
- the distance detecting means is arranged on a tailgate ei nes generic motor vehicle.
- tailgate all arrays of pivotable flaps or doors be understood in the present case, which are attached ⁇ introduced at the rear end of the vehicle.
- Such devices may be formed, for example, as upwardly or downwardly opening flaps pivotable about a horizontal axis, or as laterally-openable doors pivotable about a vertical axis.
- the arrangement of the distance detection means to the rear folding of the car is effected such that said Abstandserfas ⁇ solvents is positioned in the area of the tailgate that is located behind the motor vehicle area is open, Stel development of the tailgate is monitored by the distance detecting means on ⁇ .
- the monitoring takes place both in the resting, as well as in the movement state of the vehicle Be.
- the activation or deactivation of the distance detection means preferably takes place as a function of the opening angle of the tailgate.
- a mechanical switch similar to the well-known door contact switches in vehicle doors, or a, within the axis of rotation of the tailgate arranged angle encoder is used.
- the "normal" swivel range here refers to the, provided in commercial combination cars swivel range of about a horizontal axis, pivotable tailgate, which ends at about 90 ° to 135 ° relative to the closed position.
- Such a tailgate is, for example, for loading reasons, arranged on the "normal" pivoting range pivotally mounted on the vehicle, the tailgates are folded in particular by about 270 ° relative to the closed position on the side walls of the vehicle.
- the distance detection means arranged on the tailgate is pivoted out of the rear area of the vehicle and thus is no longer able to monitor it.
- the distance detection means is connected to an evaluation unit.
- the latter converts the signals transmitted by the distance detection means into useful data for a driver of the motor vehicle.
- the data generated by the evaluation unit are transmitted to the driver of the motor vehicle via a signal transmitter connected to said evaluation unit.
- the signal generator emits an acoustic and / or optical signal.
- an acoustic signal is emitted by the signal generator, for example, issued at variable intervals tone, which converts when reaching a defined minimum distance between the car and obstacle in a continuous tone.
- an optical signal is advantageously transmitted to the driver of the motor vehicle.
- the evaluation unit is connected to a device for controlling the motor vehicle, whereby the evaluation unit is able to intervene in the vehicle control.
- Brake pulse to be triggered which also signals to the driver in addition, that the minimum distance is reached, or the car decelerates to a standstill in case of non-engagement of the driver.
- a distance sensor as an ultrasonic sensor.
- This echo is received by the ultrasonic sensor and the duration of the pulse is determined.
- the duration of the ultrasonic pulse is then in turn converted by the, connected to the ultrasonic sensor evaluation unit in the usable for the driver of the vehicle distance signal.
- a distance measuring device of the type mentioned is in a further preferred embodiment with at least a further distance detecting means, preferably attached to the rear bumper of the vehicle combined.
- the further distance detecting means is either to an existing already in the car distance ⁇ detection means of a commercially available parking aid or a, together with an inventive Abstandsmessvor- direction, mounted to the car distance detecting means on the rear bumper.
- At least one additional distance detection means may be arranged in the front bumper of the vehicle.
- the evaluation unit of a device according to the invention Abstandsmessvor- is programmed in this further so that each of the distance detection means is regarded as relevant by which an echo of an obstacle is registered ⁇ trated first.
- a distance measuring device of the type mentioned above such that a plurality of distance detection means are arranged in the manner within the tailgate such that different monitoring areas are covered depending on the opening angle of the tailgate.
- the individual distance detection means are placed ⁇ each in a defined orientation angle on the tailgate.
- the tailgate in question is so arranged on the vehicle such that a plurality of Ar ⁇ retismes. are provided in different opening angles by a suitable device.
- the alignment angle and number of Abstandser supervisedsmit ⁇ tel are chosen so that each locking position of the tailgate is assigned at least one distance detection means which detects the rear area behind the vehicle.
- a generic distance measuring device is further not limited to the tailgate of a car but can also be used in any other vehicle door. In particular, in one or more accidentally not closed vehicle doors so the risk of collision is signaled in a vehicle movement.
- a distance measuring device of a motor vehicle 1 has a plurality of distance detecting means 4.1 and 4.2, which are arranged on the one hand in the tailgate 2 and the other in the rear bumper 5 so that obstacles in the area behind the vehicle 1 are detected by the distance detection means 4.1 and 4.2.
- the Abstandser In the tailgate 2, the Abstandser shockedsmi ttel 4.1 in the lock side Klappenfalz (not shown) are arranged.
- the tailgate 2 is attached to a horizontal (horizontal) axis of rotation 3, pivotally mounted on the vehicle 1 above.
- the activation of the distance detection means 4.1 in the tailgate 2 takes place when, in addition to the engagement of the reverse gear by the angle sensor, a previously defined value of the opening angle 6 of the tailgate 2 is detected and output.
- the angle encoder is connected to an evaluation unit ⁇ not shown).
- the evaluation unit takes over both the activation and deactivation of the distance detection means 4.1 and 4.2 in the tailgate 2 and in the rear bumper 5, as well as the evaluation of, by all distance detection means 4, over-. averaged signals and the conversion of these into a, for the driver of the car 1, usable distance signal.
- the distance signal is transmitted as an acoustic signal in the form of a tone output at variable time intervals to the driver of the motor vehicle 1 by means of an acoustic signal generator (not shown).
- This continuous tone signals to the driver of the vehicle 1 that the minimum distance to an obstacle has been reached.
- an optical distance signal is transmitted to the driver by display (not shown).
- the display has a plurality of differently colored LEDs, which light up depending on the distance of the vehicle 1 to the obstacle.
- the evaluation unit is also particularly advantageous in being able to differentiate by which distance detection means 4 an echo of an obstacle located in the movement area of the motor vehicle 1 is first received.
