Description

Cornering light system Field of the invention The present invention relates to a cornering light system, and a method in relation to such a system, according to the preambles of the independent claims.
Background of the invention The main headlamps of a vehicle are mainly pointing along the vehicle's main axis - which will not be the driving direction when cornering, i.e. when the vehicle turns left or right. When the vehicle changes directions, there are sometimes less illuminated parts of the road, in particular when turning around a corner where buildings block the sight for the driver. Pedestrians and other vehicle may then be less visible.
In order to obviate the above situation so-called "cornering lamps" are arranged at the vehicle in order to illuminate the driving path (curve) of the vehicle. The cornering lamps are mounted at the left and right front corner of the vehicle, e.g. at the respective ends of the vehicle's front bumper. When the vehicle is cornering to the right, the right lamp will be lit and vice versa and then illuminate a diagonally front area of the vehicle which increases the area lit up and thus increases the possibility for the driver to identify any object (e.g. pedestrian or vehicle) around the corner.
Generally, such cornering lights can be configured to be turned on or off in association with the turning-on or off of a directional signal switch or the steering angle of a handle (steering wheel) of the vehicle, and in addition related to the speed of the vehicle, and preferably only applied when the speed is below a preset speed limit, e.g. 40 km/h.
US-2009/0196061 discloses a vehicle cornering light arranged to improve the visibility in a diagonally front area of the vehicle. The cornering light is provided at or near a front corner of the vehicle and is configured to emit light for illuminating a diagonally front area of the vehicle.
US-2002/0015308 relates to a vehicle cornering lamp capable of broadly irradiating a road surface ahead of and in an oblique direction of a vehicle while the vehicle is moving around a curve. The lamp has multiple bulbs each with reflector at selected angle for wide viewing area.
WO-2008/156430 relates to a device and a process of cornering lights in motor vehicles. The device includes a processing unit to receive data of angular velocity of inward and outward wheels of turning vehicle, from antiskid unit in addition to signals of direction indicators.
US-2010/0213872 discloses a system and a method that relates to electronic adaptive front-lighting of a vehicle. The system comprises a fixed solid state light source that includes at least one light emitting diode, and a control unit configured to control the light source by varying the intensity in dependence of various parameters, e.g. the vehicle speed and a steering wheel angle.
US-5876113 discloses a head lamp device for a vehicle, where the head lamps are mechanically swingable in order to be capable of changing a lightning region in front of the vehicle in rightward and leftward directions. In one alternative, only the head light on the turning side may be swung or the right and left head lights may be swung by respective angles different from each other.
The inventors have identified a drawback with the presently used cornering light solutions. This drawback is present in particular when the vehicle is cornering around bigger objects (walls, buildings, etc.), and is that the light beam of the conventional cornering light (e.g. the right cornering light when turning to the right) may be partly blocked by the object and then not be able to illuminate all of driver's visual field. This situation is illustrated in figure 1 where a vehicle 2 is turning around a corner where a building 4 blocks the conventional cornering light 6 to illuminate all of the driver's visual field; in this case the field 8 is then less illuminated.
The object of the present invention is to achieve an improved system for improving the driver's visual field during cornering, and that in particular increases the driver visibility when cornering bigger objects.
Summary of the invention The above-mentioned object is achieved by the present invention according to the independent claims.
Preferred embodiments are set forth in the dependent claims.
According to a first aspect the invention relates to a cornering light system comprising a left light unit and a right light unit. The left light unit is configured, when activated, to illuminate an area to the right of the vehicle in its driving direction, and that the right light unit is configured when activated to illuminate an area to the left of the vehicle in its driving direction. A control unit is provided and is configured to control the light units by at least one control signal to be activated such that when travel conditions indicate that the vehicle is turning in one direction the oppositely located light unit will be activated.
According to a second aspect the invention relates to a method in relation to a cornering light system. Method comprises the step of controlling the light units to be activated such that when the travel conditions indicate that the vehicle is turning to the right the left light unit is activated illuminating an area to the right of the vehicle in its driving direction, and such that when the travel conditions indicate that the vehicle is turning to the left said right light unit is activated illuminating an area to the left of the vehicle in its driving direction.
At least the following advantages are achieved by the present invention. The security is increased in that there will be less dark areas behind objects when turning around corners; in addition the front of the vehicle is also better illuminated. Thus, the cornering light system according to the invention will significantly increase road safety as previously less illuminated areas will be better illuminated when the vehicle is turning.

Figure 5 is a flow diagram illustrating the method according to the present invention.
Detailed description of preferred embodiments of the invention The present invention will now be described with references to the appended figures.
Throughout the figures the same or similar items have the same reference signs.
Figure 2 is a schematic illustration of a situation for a vehicle 12 provided with cornering lights 16, 18 functioning in accordance with the present invention. In the figure it is clearly illustrated the advantage obtained by the present invention in that an area which was obscured when using the conventional technique, illustrated by figure 1, now is illuminated.
With references to figures 3 and 4 the cornering light system 10 according to the present invention will be described.
The cornering light system 10 for a vehicle 12, comprises a control unit 14, a left light unit 16 arranged in connection to the vehicle's left front corner, and a right light unit 18 arranged in connection to the vehicle's right front corner.
The light units are mounted e.g. at the respective ends of the vehicle's front bumper.
The control unit 14 is configured to receive one or many vehicle travel condition signals 20, including representations of one or many values of a vehicle travel condition(s). The vehicle travel conditions comprise values representing conditional quantities regarding the travel of the vehicle and include one or many of the vehicle speed, the steering wheel angle, the rotational speed of front wheels, the directional signal switch, navigation data; and the like.
The control unit 14 is configured to determine if the light units 16, 18 should be activated by analysing the values of vehicle travel condition(s).
Conditions for activation may e.g. be that the steering wheel angle exceeds a predetermined angle, that the directional signal switch is activated, and that the speed is below a pre-set speed limit, e.g. 40 km/h.
The left light unit 16 is configured, when activated, to illuminate an area 26 to the right of the vehicle 12 in its driving direction. This situation is illustrated in figure 4. In the figure the dashed curved line 31 indicates the projected trajectory of the vehicle.
The right light unit 18 is configured, when activated, to illuminate an area 28 to the left of the vehicle 12 in its driving direction. This situation is illustrated in figure 3. In the figure the dashed curved line 33 indicates the projected trajectory of the vehicle.
The control unit 14 is configured to control the light units 16, 18 by control signals 22, 24 to be activated such that when the travel conditions indicate that the vehicle is turning in one direction the oppositely located light unit 16, 18 will be activated. More specifically, when the vehicle 12 is turning right the left light unit 16 is activated (see figure 4) and when the vehicle 12 is turning left the right light unit 18 is activated (see figure 3).
The control signals 22, 24 are preferably supplied to the light units via a standard communication network of the vehicle, e.g. a CAN (Controller Area Network).
By activation of a light unit is meant that the light unit is set in an active mode and starts emitting light. The light might be ramped up to a maximal level or be set at a maximal light level directly.
The active mode exists as long as it is determined that the vehicle is turning; when it is determined that the vehicle no longer is turning the light unit is set in a passive mode. The light is then gradually decreased, or be turned off directly.
More specifically, in order to determine that the vehicle no longer is turning, the travel conditions are analysed, e.g. it is determined if the steering wheel angle is essentially zero, if the directional signal switch is not activated, and if the speed is above a pre-set speed limit, e.g. 40 km/h. If preferably all these conditions are fulfilled it is determined that the vehicle no longer is turning and the light unit is set in a passive mode. In addition, it may be advantageous, in particular for longer vehicles, to keep the active mode during a pre-set time period (some seconds) or distance (in the range of 10-50 meter) after the turning in order to allow the vehicle to straighten out.
Furthermore, it may also be possible to vary the intensity of the light in the illuminated area during the active mode, i.e. to achieve a time-dependent intensity. It may also be possible to vary the intensity in dependence of the angle of the emitted light in relation to a line L1 perpendicular to a longitudinal axis A of the vehicle 12. For example, the smaller angle the higher intensity.
The illuminated area is defined in relation to a line L1 perpendicular to a longitudinal axis A of the vehicle 12, and running through the left and right light units 16, 18.
The illuminated area 28 to the left of the vehicle 12 (see figure 3), which is illuminated by the right light unit 18, is defined by an angle u1, delimited by the line L1 to the left of the vehicle and a line L2 running obliquely to the left, in relation to line L1, from the right light unit 18.
The angle u1 is preferably in the range of 30-45 degrees.
In some occasions it is not possible to illuminate the entire area up to the line L1, e.g. due to limitations of the light unit. In that case the illuminated area is defined by line L3 and line L5, being separated from L1 by a small angle v1, e.g. in the range of 0-10 degrees.
And similarly, the illuminated area 26 to the right of the vehicle 12, (see figure 4) which is illuminated by the left light unit 16, is defined by an angle u2, delimited by the line L1 to the right of the vehicle 12 and a line L3 running obliquely to the right, in relation to line L1, from the left light unit 16.
The angle u2 is preferably in the range of 30-45 degrees.
In some occasions it is not possible to illuminate the entire area up to the line L1, e.g. due to limitations of the light unit. In that case the illuminated area is defined by line L2 and line L4, being separated from L1 by a small angle v2, e.g. in the range of 0-10 degrees.
A light unit comprises one or many light sources, e.g. light emitting diodes, conventional lamps, etc.
According to one embodiment the light units 16, 18 are separate cornering light units.
As an alternative the light units 16, 18 are integrated with other light units of the vehicle, e.g. main light units, parking light units or fog light units of the vehicle.
Thus, the cornering light units according to the present invention are configured to illuminate in the "wrong" direction. Within the scope of the present invention as it is defined by the appended claims it is also possible to configure and control the light unit such that when the travel conditions indicate that the vehicle is turning in one direction the light unit at the same side as the vehicle's turning direction will be activated in order to illuminate an area at said same side, i.e. to include the conventional cornering light function into the system according to the present invention. In that regard the light units 16, 18 are used in combination with one or many conventionally functioning cornering light units. The control unit 14 is then configured to control the one or many conventionally functioning cornering light units to be activated in combination with the light units 16, 18. These conventional cornering light units may be an integral part of the cornering light units 16, 18.
The present invention also relates to a method in relation to a cornering light system 10 for a vehicle 12.
The method is schematically illustrated by the flow chart in figure 5.
The cornering light system has been described above with references to figures 3 and 4, and comprises a control unit 14, a left light unit 16 arranged in connection to the vehicle's left front corner, and a right light unit 18 arranged in connection to the vehicle's right front corner.
The method comprises: - receiving, by the control unit, one or many vehicle travel condition signals (20), including representations of one or many values of a vehicle travel condition(s). Different vehicle travel conditions have been discussed above. The method in addition comprises: - determining if the light units 16, 18 should be activated by analysing the values of the vehicle travel conditions. The analysis of the values are made e.g. by comparing the values to predetermined thresholds.
The method further comprises the step of: - controlling the light units 16, 18 to be activated such that when the travel conditions indicate that the vehicle is turning to the right said left light unit 16 is activated illuminating an area 26 to the right of the vehicle 12 in its driving direction. And when the travel conditions indicate that the vehicle is turning to the left the right light unit 18 is activated illuminating an area 28 to the left of the vehicle in its driving direction.
When it is determined that the vehicle no longer is turning the light units are controlled to go back to the passive mode as discussed above.
As described above the illuminated area is defined in relation to a line L1 perpendicular to a longitudinal axis A of the vehicle 12, and running through said left and right light units 16, 18. It is herein referred to the discussion above in relation to the detailed description of the cornering light system and with the references to figures 3 and 4.
The present invention also relates to a computer program P, see figures 3 and 4.
The computer program P comprises a computer program code to cause the control unit 14, or a computer connected to control unit, to perform the method steps described in detail above. The control unit 14 includes the necessary circuitry required to execute the computer program, e.g. a processer and a memory.
The present invention also relates to a computer program product comprising a computer program code stored at non-transitory computer-readable medium, e.g. a memory, to perform the method steps described above, when the computer program code is executed by the control unit or by a computer connected to the control unit.
The present invention is not limited to the above-described preferred embodiments. Various alternatives, modifications and equivalents may be used. Therefore, the above embodiments should not be taken as limiting the scope of the invention, which is defined by the appending claims.
