Device for determining the length of the "when parking a motor vehicle in a parking space to drive routes,» The invention relates to a device for determining the length of the routes to be driven when parking a motor vehicle in a parking space between two vehicles parked one behind the other. It is known for Many drivers find it difficult to reverse a motor vehicle into a parking space, the length of which is just sufficient or the required minimum length only slightly exceeded

The invention solves the problem of reducing the length of the parking a motor vehicle in a parking space to be driven routes to be determined in such a way that there is no risk of bumping into the turned off There is a vehicle and the vehicle to be parked comes to a short distance parallel to the curb without it being on the curb bumped into

The invention consists in that in front of an indicator disc Pointer according to the distance traveled by the motor vehicle by a drive actuated while driving the motor vehicle ver adjustable and the following identification marks are attached to the indicator disc s

a) Starting position in which the device is to be switched on when the vehicle to be parked is approximately parallel at the usual small distance so next to the vehicle behind the parking space is so that its front edge is in the line of sight of the driver of the vehicle to be parked,

b) identification mark for the position to which the einzuparkende vehicle in the parked vehicles to - drive up approaching parallel direction is _e

c) Identification label for the point up to which the vehicle is to be parked The vehicle is to be driven backwards with the controls turned to the right as far as possible,

d) Identification mark for the point up to which the vehicle to be parked has been turned to the left as far as it will go To drive the control backwards is · The specifications for turning the control to the right and left apply to the parking spaces that are most common in practice on the right-hand side of the street. When a Vehicle ζ · Ββ in a one-way street, to be parked on the left side of the street, are only in the Points c) and d) to swap the directions to the right and to the left

It is a necessary prerequisite for parking a motor vehicle that the parking space is long enough » An advantageous embodiment of the inventive The device is that on the display disc an identification mark for the required minimum length of the Parking space is attached. The pointer must have this identification mark have happened after the vehicle has moved up from the starting position to the point from which from which the driver hai the rear edge of the vehicle parked in front in his line of sight » The line of sight runs perpendicular to the longitudinal axes of the vehicles*

The device according to the invention can of course also be switched off again with its own on-switch. But since the ignition is almost always off when the vehicle is parked · » is switched, it is advantageous to design the device according to the invention so that it is switched off when the Ignition is switched off and can only be switched on again with its own on switch.

The pointer must be on the identification mark for the starting position if the device according to the invention is switched on at the beginning of parking and the vehicle to be parked is at the point indicated under a). For this purpose, the pointer can be manually adjusted to the starting position, for example by means of a friction clutch, as is known in clocks. More advantageous, however, is the design of the device according to the invention that the pointer automatically returns to the starting position when it is switched off has exceeded the identification mark for the end of the route to be driven forward or the identification mark for the end of the route to be driven backwards. The device is automatically switched off in this embodiment, when the driver decides to continue forward and not park the vehicle, for example, because it has determined that the parking gap is too short, or if the parking has ended _e Detachment can be effected, for example, by switching cams, which _# / _e

Because the pointer in this embodiment is only between two can be adjusted to fixed limits, it can easily be returned to the starting position after the device has been switched off - be guided, for example, like a measuring instrument, its pointer is adjusted against a spring force that returns it to its original position after switching off » An advantageous embodiment of the device according to the invention consists in that the drive of the pointer (Z) to the speedometer - meter shaft is coupled »

A further advantageous embodiment of the device according to the invention is that when the marks are reached by identification Audible signals are given in the designated areas ^ Then the driver does not need the display screen while driving to keep an eye on * on the visible display can can even be dispensed with completely #

In the figure it is shown how the vehicle D with the help of the device according to the invention is to be driven into the parking space E between the two parked vehicles B and C « The vehicle D is first driven to a point where it is approximately parallel to the vehicles B and C at a distance h from vehicle B is and the driver F sees the front edge of vehicle B in his line of sight Z, the axes to the longitudinal the vehicle is vertical The indicator disc A is installed on the dashboard of the vehicle D in such a way that it is visible to the driver F. The pointer Z is rotated by a drive, not shown, which is preferably coupled to the speedometer shaft, such that the Angle of rotation of the pointer Z of the Streoke driven by vehicle D.

is proportional. In the starting position 0, the device according to the invention is switched on with its own switch, not shown, it can be coupled to the speedometer shaft, for example, by an electromagnetic coupling, which is released again when the device is switched off »The device can be switched off by its own Switch and the ignition switch of vehicle D take place _o

The pointer Z can be set to the starting position 0 by hand e.g. by a slip clutch, as it is known for watches *

But the inventive device may also be configured so that the pointer Z automatically returns to its initial position 0 when the device is turned off ,, In the figure, the points are located, between which the vehicle is to drive back when Binparken before or ₀ · A dashed reference line and the indicator disc A with the corresponding position of the pointer Z are drawn at the point where the driver is located «Vehicle D is first driven straight ahead« When his driver reaches point 2 and the rear edge of the front parked vehicle C has in its line of sight L, the pointer Z must have passed mark 1 or at least he has reached, because mark 1 indicates the minimum length of the parking space required for vehicle D. The vehicle D must be driven up to position 3 »If the vehicle D continues to drive up, the device according to the invention can be switched off automatically. Then the vehicle D is driven back fcls to position 4. The right front wheel V rolls on the curve KIT 1 and the reohte £ / »

■ Rear wheel H on curve EhI. At the point 4 the control Then, if possible, turn it to the left as far as possible while standing the vehicle D moved further back to the point 5. There it is parallel to the curb at a small distance from this. The last time you reverse, the front wheel V rolls up the curve Kv 2 and the rear wheel H on the curve Kh2. When the parking is finished and the pointer Z crosses the marker 5, the device can be switched off automatically »The distance h between the vehicle D to be parked and the parked vehicle Vehicle C should be as precisely as possible a specified size, e.g. Of5 m »If the parked vehicle O» is significantly wider If the car to be parked is D, point 3 is expediently at the difference in width to the front and point 4 by the same To relocate the route backwards so that the vehicle D is back at point 5 at a small distance from the curb to this parallel stands «In this case, however, the parking space must be longer by the difference in width, i.e. the distance d between the Positions 1 and 2 must be at least equal to this difference in width.

If the driver is certain that the parking space E is long enough, he can also go to the described checking of this prerequisite do without, drive straight to position 2, there the pointer Z between the identification marks 1 and 5 according to a manual estimate and then drive forward until the pointer is on the identification mark 3 stands. Reversing is also carried out in the manner described «

It goes without saying that the location of the identification marks on the Indicator disc of the length and the smallest turning circle of the
