Definitions
- the invention relates to a method for optimizing a vehicle light and a headlamp device according to the generic features of claim 1.
- DE 197 19 573 AI discloses a static cornering light, wherein the cornering is detected via a Steering Impact Sensor or yaw angle sensor and if the speed of the vehicle is below 60 km / h, the inside fog light is switched as cornering or cornering light.
- the cornering light is coupled to the low beam and / or high beam of the motor vehicle, so that the cornering light only switches on when one of the main lights is turned on.
- EP 0 832 785 B1 discloses a method for adapting a vehicle light when cornering, wherein a cornering light is generated with a light distribution having a larger horizontal scattering range than that of the low beam, wherein a low beam distribution of a fog light is regulated in accordance with the cornering of a low beam with a low beam distribution is switched on.
- the cornering light does not have to be generated by a single reflector of the headlamp unit, but by two reflectors, namely a low beam reflector of a first Headlamps and a fog light reflector of a second headlamp.
- JP 60099737 Al discloses a cornering light which is turned on when a turn signal is activated. Activating the left turn signal activates cornering light on the left side. The cornering light is automatically deactivated again after a certain time after deactivating the turn signal.
- the system is always set very sensitively, so that at each steering wheel angle change, a change of the static cornering light or cornering light takes place.
- the additional light distribution is applied to each mini-curve or too early and every small steering wheel angle change.
- the system can also be set insensitive. The switch is then always relatively late. Both types of engagement, whether sensitive or insensitive, are not optimal for illumination of the turn or turn and cause confusion to the driver through rapid and frequent changes.
- the object of the invention is therefore to improve a vehicle light as a static cornering light or cornering light so that an entrance into a street is optimally illuminated early without causing irritation to the driver.
- a significant advantage of these embodiments is that with the inventive cornering light the junction is illuminated in a street before the actual turning process. Especially with poorly lit streets It is of great advantage if the junction with the turn-off road can already be seen and estimated ahead of time.
- the 'driver is not obliged to curb his normal speed strong, so as not to miss the junction or departure. However, it must fall below the maximum speed of usually 60 km / h, so that the static cornering light is activated. However, this is usually the case when the driver intends to drive on a bend.
- the turn-on curve for the cornering light is lowered by a setpoint with activated direction indicator, so that the static cornering light is activated earlier with the same turn signal with activated turn signal than with non-activated turn signal.
- the system reacts more sensitively when the direction indicator is activated.
- the direction indicator is activated, the static cornering light is activated even at a low steering angle.
- FIG. 1 is a schematic representation of a headlamp device with the arrangement of the Kurvenlicht- or turning 1ichtfunktion,
- FIG. 2 shows diagrams for activating the cornering light
- FIG. 3 shows diagrams for activating and deactivating the additional light in the case of a combination of static cornering light and cornering light
- Fig. 1 shows a schematic representation of a headlamp device with the arrangement of the cornering or cornering light function.
- different light functions such as the low beam 2, the high beam 3, the turn signal 4, and the additional light 5, which is arranged as cornering light and / or static cornering light in the headlight.
- a fog light 6 is arranged separately from the main headlight 1. This fog light 6 is usually arranged in or on the bumper 7 and is actively switched on by the driver in the event of fog.
- the cornering light 5 is separated from the main headlight 1 and separated from the fog light 6, but arranged next to the fog light 6 in the bumper 7.
- the additional light 5 could also be integrated into the fog lamp 6.
- the fog lamp 6 could serve directly as additional light 5, which is then activated as usual as a fog lamp 6 by the driver or as a cornering light and / or static cornering light 5 is switched according to the switch-on.
- it can also be an independent light source or an independent light source with its own reflector integrated as an additional light 5 in the fog lamp 6.
- the cornering light and / or static cornering light has its own light distribution. This light distribution is switched on as cornering light and / or static cornering light of the low beam distribution.
- an additional light 5 is provided with a horizontally broader light distribution, wherein for the activation of the cornering and / or cornering light the cornering or Abbiegelichtverver connection of the low beam distribution is switched on.
- the cornering light is a static cornering light, since the Headlight not moved along the curve, but only by connecting the additional light, the new light distribution is realized.
- the fog lights have a right and left fog lights, with a steering angle to the left only the left auxiliary light is activated, while at a steering angle to the right only the right auxiliary light is activated.
- auxiliary headlight 5 itself does not move, but there is only one connection of the cornering and / or cornering light, with a static cornering light at a maximum speed of usually 70 km / h (between 60 and 80 km / h festlegbar) or a cornering light at a maximum speed of 40 km / h is realized.
- Fig. 2 shows graphs for activating the cornering and cornering light. It is a turn-on and off characteristic for the vehicle shown. It shows the steering angle impact over the speed of the vehicle. An intervention of the cornering light takes place only when falling below a maximum speed v max . Above this speed v max , the additional light is always switched off.
- the switch-on characteristic curve is lowered by an offset, so that the turning-on of the cornering light takes place even if the steering wheel angle LRW is smaller.
- the diagram on the right shows the regulation of the turn-on of the cornering light. The status of the direction indicator above the speed V is shown.
- v maxF RA is usually set at 40 km / h and v max at 70 km / h.
- v maxF RA is usually set at 40 km / h and v max at 70 km / h.
- cornering light is activated.
- the cornering light is switched on and off as a function of the steering angle.
- the activation takes place in accordance with the steering angle.
- the cornering light is deactivated.
- the switching off of the cornering light is controlled via the steering wheel angle, analogous to the switch-off characteristic in the left diagram.
- FIG. 3 shows diagrams for activating and deactivating the additional light in the case of a combination of static cornering light and cornering light.
- the cornering light is active below a maximum speed v maxFRA .
- the direction indicator is activated and below the maximum speed v maxFRA .
- the cornering light is always switched on.
- the direction indicator is deactivated, the turning on and off of the cornering light is analogous to the characteristic curves in the associated left diagram as a function of the steering wheel angle.
- the static cornering light is switched off analogously to the switch-off characteristic curve in the left-hand diagram as a function of the steering wheel angle.
- FIG. 4 shows a diagram for activating and deactivating the static cornering light.
- An activated turn signal below v maxF RA will make the system more sensitive.
- the switch-on characteristic for the static cornering light is reduced by a specific setpoint, so that the turning-on light is already switched on when the steering wheel angle is low.
- the switch-off characteristic is lowered by a specific setpoint, so that the turning off of the cornering light takes place later with a smaller steering wheel angle.
- the direction indicator has directional priority over the steering wheel angle. For example, if the left steering wheel is activated in a roundabout and the right direction indicator is activated, the left cornering light goes off and the right cornering light goes on.
- the switch-on and switch-off characteristics correspond to a constant radius of curvature over the entire speed range. By understeering the vehicle with increasing speed and constant radius of curvature, the required steering wheel angle increases so that the cornering light is activated.
- the switch-on line is 80m without the direction indicator being activated, and with the direction indicator switched on it is 450m.
- the switch-off line without activated direction indicator is 250m. There, the turning off the cornering light.
- the switch-off line with activated direction indicator is on the other hand 500m.
- The; Approach and AbsehaltVorgang the cornering light via a ramp function.
