Description

  • The invention relates to a device for parking space measurement according to the preamble of the main claim. From the DE 38 13 083 A1 A parking system is already known, which misses a parking space during a pass and then supports the driver during a parking operation. The page to be parked on is selected by the driver by manual input. From the DE 102 58 310 A1 A method is known for determining a suitable parking space, in which a vehicle side is automatically selected on which a parking space measurement is carried out to search for a parking space suitable for parking.
  • Lead the invention
  • The inventive device for parking space measurement with the features of the main claim has the opposite Advantage that the driver automatically, without requiring a directional input required by the driver, the result of a parking space measurement is displayed on a preferred side of the vehicle. This requires the driver only request the display of a parking space measurement. A Page selection is not required. This automatically becomes a result a parking space measurement for the common Einparkvariante specified, namely for right-hand traffic on the right side of the vehicle or for left-hand traffic on the left side of the vehicle. This will make the use of a parking space measurement for one Driver relieved.
  • By in the subclaims listed activities are advantageous developments and improvements in the main claim specified device for parking space measurement possible. Especially It is advantageous to provide an operating element with which instead the result of the preference page or, in addition, the result of a Parking space measurement for the other vehicle side is displayed. Although in this case a Page input is required, however, this input may be from the user be made in a simple way, since not one page specified must be, but only an ad of another page at all must be initiated. Advantageously, such an output of a Note on another side then, if either the parking space on the preferred side is quite narrow and the driver on the opposite side another parking space sees. Another application exists for the case when parking is possible on both sides, e.g. in a one-way street.
  • In a particular embodiment is the measurement of the parking space only with the operation the control unit for triggering triggered the display of the result. This can be one of not desired by a driver Measurement be prevented. In another embodiment but it is also possible that the measurement is made silently, and as prompted by the user only comes to a result for display. One of one User wanted Result can be displayed very quickly after the request become.
  • In a further embodiment It is advantageous that compared with a particularly low parking space to a parking space on the preferential side of the driver in addition to or instead of the parking lot on the preferential side on the parking possibility on the preferential side opposite Page is pointed out.
  • Farther it is beneficial for the display of parking space measurement to use the display of a distance warning unit. Especially intuitive the length a parking space then be detected when the length the parking space is shown in color.
  • Further it is advantageous to provide a switching unit on the device for parking space measurement, with which the preferred side can be adjusted. This is e.g. then advantageous if a vehicle type in countries with left-hand traffic and with right-hand traffic is delivered to a country-specific Adjustment to make. Furthermore, a switching unit is advantageous when a vehicle operate in a country with a different traffic direction should. If e.g. a vehicle from a country with right-hand traffic in a country with left-hand traffic brought, so can with the switching unit the preferred page can be changed from right to left.

In particular, it is advantageous for motor vehicles that are move in a road network. Therefore, the invention is further exemplified by a motor vehicle explained.
  • In the 1 is a motor vehicle 1 shown in which both in the area of a front 2 , as well as in the area of a back 3 of the vehicle 1 Ultrasonic sensors are arranged. Instead of ultrasonic sensors, any other suitable distance sensors can also be used. In the sensor configuration shown here are four ultrasonic sensors 4 on the front side 2 arranged so that they point forward in the direction of travel. Another sensor 5 points to the left side of the vehicle 11 and another sensor 6 points to the right side of the vehicle 12 , At the vehicle rear 3 a corresponding sensor configuration is provided, with four sensors 7 in the reverse direction, while also a sensor 8th on the left side of the vehicle 11 and another sensor 9 on the right side of the vehicle 12 shows. The sensors 4 . 5 . 6 . 7 . 8th . 9 are over a data bus 13 with an evaluation unit 10 connected. The ultrasonic sensors are from the evaluation unit 10 also controlled. They each emit ultrasonic signals from obstacles in the vicinity of the vehicle 1 be reflected. From the transit time of the ultrasonic signals, a distance between the vehicle and the obstacle is calculated taking into account the speed of sound. For this purpose, the evaluation unit 10 an arithmetic unit 14 on. If there is a distance to an obstacle, an acoustic warning can be given via a loudspeaker 24 be issued. In a message 16 also visual warnings can be issued. The ultrasonic sensors are arranged on the vehicle such that the parking space or the obstacle can preferably be spatially detected by the sensors arranged respectively on the corresponding vehicle side when driving past a parking space or an obstacle, and the result of the detection by the computing unit 14 can be evaluated. In a store 15 are the dimensions of the vehicle 1 stored. By comparing the measured parking space with those in the memory 15 stored vehicle dimensions, the arithmetic unit 14 decide whether the parking space is suitable for the vehicle. In a preferred embodiment, the arithmetic unit can subsequently via the display 16 or the speaker 24 provide the driver with driving instructions on how best to park in the parking space. In a further embodiment, one in the 1 not shown adjusting unit automatically the steering and / or the drive unit of the vehicle are controlled for an automatic parking operation.
  • For a parking space measurement, all ultrasonic sensors can be used. However, a parking space measurement is preferably carried out in the case of a lateral passage past the parking space. The parking space is then either on the right side of the vehicle 12 or on the left side of the vehicle 11 , Accordingly, only the sensors will be used for the parking space measurement 6 . 9 or 5 . 8th operated on the vehicle sides. In a preferred embodiment, the sensors are thereby from the evaluation unit 10 controlled so that they can safely detect obstacles at a higher pass speed at a parking space obstacles. For this purpose, the measuring intervals of the ultrasonic sensors and / or the intensity of the emitted signal can be varied.
  • In a first embodiment, a parking space measurement by an operation of a control unit 17 started, eg by pressing a button 18 the control unit 17 , As soon as a suitable parking space has been found, it will be shown on the display 16 shown. For the measurement is in the memory 15 a preferred page filed.
  • By way of example, the following is based on a left-hand drive vehicle which is controlled in a traffic system with right-hand traffic. The preferred side is the right side of the vehicle 12 provided, as is generally parked in right-hand traffic on the right side of the vehicle. By pressing the button 18 So are the ultrasonic sensors 6 . 9 on the right side of the vehicle 12 activates and measures a parking space on this page. As soon as a parking space is found, it will be displayed 16 shown. A selection of the preferred page itself does not have to be done, since these are already in the memory 15 was determined. In one embodiment, a measurement of possible parking spaces is performed only on the preferred side and a result is displayed. In a further embodiment, measurements can also be carried out on the opposite side, wherein according to the invention at least initially only one result is displayed on the preferred side.
  • If a driver nevertheless wishes to park on the left-hand side of the vehicle, whether he recognizes a more suitable parking space there or if he is in a one-way street on which parking is permitted on both sides of the vehicle, the driver can actuate another operating element also request an indication of a parking space on the left side of the vehicle. In a first embodiment, the driver can make this selection by operating another control element 19 the control unit 17 Request. In another This embodiment can also be a position of a turn signal lever 20 be evaluated. If, for example, the driver flashes briefly to the left, possibly without even emitting a turn signal, the display changes to an indication of a parking space on the left side of the vehicle. In a further embodiment, parking spaces on the left side of the vehicle in this selection also in addition to parking spaces on the right side of the vehicle in the display 16 being represented.
  • In a further embodiment, it is also possible that a parking space measurement is automatically activated when falling below a certain speed of the vehicle. This speed is preferably in a range of 20 km / h-50 km / h. To determine the speed of the vehicle, the evaluation unit 10 connected to a corresponding motion sensor on the vehicle, such as a wheel speed sensor 21 , If the speed falls below 40 km / h, for example, a parking space measurement may possibly be on both sides of the vehicle 11 . 12 in another embodiment, but only on the preferred side, the right side of the vehicle activated. An indication of found parking spaces in the display 16 stops first. However, a user presses the button 18 , so found parking spaces on the festged preferred side of the vehicle in the display 16 displayed.
  • The evaluation unit 10 has an interface in a preferred embodiment 22 on, with which the preferential side can be changed. If, for example, a vehicle is moved from a right-hand traffic area to a traffic area on the left, it can be accessed via the interface 22 or via the control unit 17 the preferred page will be changed. About the interface 22 can also be a factory setting of a device according to the invention for parking space measurement in the vehicle manufacture done.
  • In a further embodiment, in a mutual measurement of possible parking spaces by means of the ultrasonic sensors on both sides of the vehicle 11 . 12 Even then hints are issued to a parking space on the opposite side, if the evaluation unit on the preferred side only detects a parking space that is unfavorable by a predetermined amount for parking, as on the opposite side. If there is a parking space on the preferred side which, due to its extent, is only scarcely sufficient for parking in relation to the vehicle dimensions, but a sufficiently adequate parking space is available on the opposite side, this is also indicated to the user in a preferred embodiment 16 shown. A parking operation, the user can then by another, in the 1 trigger operation not shown.
  • In a further embodiment, it may also be provided for a reconciliation of the proposed preferred side, a steering angle sensor 23 evaluate. If a driver steers contrary to the preferred direction, this is expressed as a desire, if necessary, to park on the opposite side.
