Definitions
- the invention relates to a method for switching high beam in a road vehicle, especially in cars and trucks, wherein the high beam can be switched both automatically according to a sensor device by an automatic function with an activated and a deactivated state and manually by operator actions and an operator a manual switching of the high beam overrides the automatic function, at least temporarily.
- the invention relates to a high beam circuit for a road vehicle, especially in cars and trucks, with a switchable between high beam and low beam illumination device, a sensor device for determining at least one optical environment parameter, a control unit with an activatable and deactivatable automatic function for automatically switching the illumination device in dependence the environmental parameter and a control unit for generating switching signals by an operator, which can be used to prioritize the manual switching of the lighting device.
- DE 196 22 493 C5 discloses a generic automatic high beam circuit, in which a light sensor sends a control signal (activation, deactivation signal) to an associated electronic unit, according to which the high beam is automatically switched on and off.
- a manual switching on and off of the high beam by means of a steering column lever which is pivotable in the direction of travel or against this.
- a slight pivoting in the direction of travel corresponds to a light horn function, while continuous operation is possible by overcoming a pressure point.
- By subsequent pivoting against the direction of travel occurs manual shutdown.
- the cited document is particularly not removable, as and with what kind of controls, the automatic function of the prior art high beam circuit can be activated and deactivated, for which usually its own additional actuator will be provided, which reduces the ease of use and increases the design effort.
- DE 41 11 210 A1 describes an automatic on / off switch for the lighting system of a motor vehicle using a light sensor, by which the low beam can be switched on and off when the high beam is switched on at twilight. Other automatic switching functions are not provided. Each time the car is turned on or off automatically, a warning light comes on to alert the driver of the malfunction.
- DE 44 03 937 A1 discloses an automatic lighting circuit for motor vehicles, in which light sensors are combined with a device for recognizing the road type.
- the proposed lighting circuit has a first fully automatic operating mode and a second operating mode in which the circuit only indicates to the driver a lighting suggestion. The modes are switched manually.
- This lighting circuit is combined with a conventional lighting control and can be switched on and off by an operator - by means of an additional control element.
- the invention has the object of providing a method and a high beam circuit of each type mentioned while avoiding the disadvantages listed above to the effect that in principle without additional controls a fully automatic high beam circuit can be realized, with an expected manual operation, in particular the Lichthupen function (eg by pulling a steering column lever against the direction of travel when the main beam is switched off), even when the automatic function is activated should remain unchanged.
- an expected manual operation in particular the Lichthupen function (eg by pulling a steering column lever against the direction of travel when the main beam is switched off), even when the automatic function is activated should remain unchanged.
- the object is achieved in a method of the type mentioned in that by a first operation to turn on a given at the time of the control action continuous operation of the high beam and by a second operation to turn off at the time of the control action given continuous operation of the high beam each at least one state change the automatic function is initiated.
- the automatic function of the proposed high-beam circuit is switched on or off solely by the actuation of devices (change between activated and deactivated state, hereinafter referred to as state transition), which also in a conventional manner for manually switching on and off the high beam be used. Since, according to the invention, only the two actuation processes are used for this purpose which, when the (main) high beam is switched on, cause the same to be switched off and, when the main beam is switched off, to switch it on permanently, e.g.
- the typical flare function switch-off motion when the high beam is switched off
- the typical flare function remains unaffected and can continue to be available, which has a very positive effect on operating convenience since the operation remains in line with expectations. ie the operator - usually the driver - is not confronted with variable operations depending on the state of the automatic function.
- the first and second operator actions are different operator actions, such as preferably pressing and pulling a suitably trained Facility.
- a preferred embodiment of the high-beam circuit according to the invention is characterized in that the second switching signal at the time of its generation off main beam is independent of a current state of the automatic function to a limited duration limited switching of the high beam in the manner of a flasher available.
- the operating unit has a single operating element for generating the switching signals.
- care is taken in a comparable manner that the operator actions are performed on a single operating element.
- the first and second operator actions may be different operator actions.
- the operating unit - as already mentioned - a shift lever in particular a known steering column lever, have as a control element.
- the shift lever preferably has a monostable neutral position and a first shift position and a second shift position, from which the shift lever automatically springs back into the neutral position, which is advantageously arranged centrally between the first and second shift positions.
- the first switching position such as pivoting of the lever in driving position, direction (pressing)
- the first switching signal and in the second switching position such as a pivoting counter to the direction of travel (pulling)
- the second switching signal to be generated.
- an automatic function activated at the time of the operator's action i. Automatic "On” in addition to the high beam in accordance with the operator actions are switched on or off.
- the manual control action overrides the automatic mode by switching the high beam directly on or off due to the operator action.
- the high beam in the automatic mode can be switched on and off at any time by the operator when the light or road conditions require it.
- a state change of the automatic function causes, i. Automatic "off".
- a high-beam circuit according to the invention can be provided in a corresponding manner that at the time of the generation of the switching signal activated automatic function this in addition to deactivating the automatic function and for switching the illumination device is available.
- a corresponding operation does not directly affect the lighting device, but initially only the automatic function is activated or can be activated (automatic "on"), which then then according to specification the sensor device performs the switching on or off of the high beam.
- the display device for displaying the activation state of the automatic function in signal-operative connection with the control unit, by means of which the current state of the automatic function of the operator is indicated by the method.
- the display device is advantageously designed as an optical display device, for example in the form of a status light (status LED), and can both represent a separate unit and be combined with the above-mentioned high beam display.
- the display device preferably displays the (activation) state of the automatic function permanently.
- the operator can be informed by the instrument cluster, for example by means of a text message or a corresponding icon on the state of the automatic function, where supportive color codings can be used.
- the automatic function is advantageously activated by default, i. before the first operation of the intended controls by the operator after successful - possibly automatic - commissioning of the vehicle lighting system set such that initially takes place at appropriate light and traffic conditions automatic fade.
- FIG. 1 shows a schematic block diagram of a high-beam circuit according to the invention
- FIG. 2 shows a preferred embodiment of an operating element of the high beam circuit according to FIG. 1;
- Fig. 3 is a flow / state diagram for the representation of
- FIG. 4 shows a display device used in a high-beam circuit according to the invention.
- Fig. 1 shows schematically a high-beam circuit 1 according to the invention, as used in a road vehicle, not shown, in particular a passenger car (PKW) or truck (truck) or the like, is used.
- the high-beam circuit 1 has a sensor device 3, which serves to determine at least one environmental parameter UP, which is symbolized by a drawing pointing to the sensor device 3 arrow.
- the lighting device 2 and the sensor device 3 are connected to an electronic control unit 4 in signal-technical operative connection, which is shown in Fig.
- the environmental parameter (s) determined by the sensor are preferably optical parameters, such as the ambient brightness.
- the optical environment parameters can usefully be supplemented or replaced by non-optical parameters, such as navigation data, radio signals via the infrastructure - for example, a radio marking of entrance or exit, tunnel entrance and exit.
- the high beam circuit 1 still has an operating unit 5, which is also in signal communication with the control unit 4.
- the operating unit 5 is designed to generate switching signals D, Z (see below) by an operator, not shown, for the purpose of prioritized manual initiation of the switching of the lighting device 2 and / or for activating / deactivating the automatic function AF, hereinafter also referred to as "automatic” designated by the control unit 4 can be used.
- the high beam FL is manually switched on and off by the operator via the control unit 5), which is also in operative signaling connection with the control unit 4.
- the operator receives information as to whether the automatic is currently on or off.
- the operating unit 5 of the high beam circuit 1 shown in FIG. 1 in plan view is shown in more detail.
- the operating unit has in the embodiment shown a single control element 7, which is designed in a conventional manner as a steering column lever. This cooperates with a switching unit 8, via the signal output 9 corresponding operating signals in the form of switching signals D, Z to the control unit 4 (Fig. 1) are available.
- the operating element 7 and thus the switching unit 8 have three switching positions N, D, Z, which each have a corresponding (switching) signal of the switching unit 8 and thus the entire operating unit 5 is assigned.
- these signals are designated below by the same reference numerals as the assigned positions N, D, Z of the pitman arm.
- the latter is formed in the embodiment shown as a monostable lever that springs back after actuation in one of the directions of the double arrow in Fig. 2 in the middle neutral position N, in which the switching unit 8 generates no switching signal.
- Switching signals are generated when the operator pivots the operating element 7 in the forward direction FR of the road vehicle or against it ("pushes", D or "pulls", Z).
- These states ST1-ST4 also represent logical control states of the suitably embodied electronic control unit 4 (FIG. 1), which has a corresponding operating and display logic.
- the high beam FL is then switched in accordance with the sensor device 3 by the control unit 4, see. FIG. 1.
- the properties of each state are displayed to the operator, cf. FIG. 4.
- the automatic mode is also independent of the activation state, as with conventional manual switching a light horn function LH available, each of which can be actuated by pulling Z, without causing it to affect the automatic.
- a readiness display for automatic operation is provided.
- Fig. 4 The figure shows schematically a typical combination instrument 10 of a car, in which different instruments, such as speed or tachometer, integrated, which is known in the art and is not detailed here.
- the combination instrument 10 has a first display device 11, which indicates when the high beam is switched on, for example, by lighting up blue.
- 4 additionally has a second display device 6 (see FIG. 1) which is connected to the control unit 4 or a display logic contained therein and indicates whether the automatic system is switched on or off.
- the display devices 6, 11 may also be combined in the form of a single display device.
- the automatic function is basically in standby, and is selected or deselected only depending on the operation of the shift lever 7, for the description of another preferred embodiment, the basic readiness of the automatic function of the operator via a separate control can be optionally switched on or off.
- Fig. 5 corresponds to the lower part of Fig. 3 with respect to the states ST3 and ST4; the states ST1 and ST2 are no longer available due to the switched off readiness of the automatic function.
- the circuit In the off state of the high beam circuit ST4, the circuit is converted by pressing D on the control element 7 in the on state ST3 and by pulling Z the flasher LH is triggered.
- the high beam circuit ST3 When the high beam circuit ST3 is switched on, the circuit is switched to the switched-off state ST4 by pulling Z on the control element.
- the separate control element may be an existing rotary light switch, in which an additional stage is integrated for switching on and off the readiness of the high-beam automatic function, so that four levels can be switched with this switch, for example:
- the 4th stage can be carried out non-latching, so that the knob with which such rotary switches are usually provided, after operation back to the position 3.
- a light-emitting diode may be provided in the light rotary switch.
- the readiness of the high-beam automatic light system can alternatively also be linked to the setting of the automatic driving light, that is to say to the third stage.
- Another alternative to set or deselect the readiness of the high-beam automatic is to make appropriate settings by a menu-driven operation recordable example of the instrument cluster.
