Description

Technical Field

[0001] The present invention relates to a system for automatically activating vehicle headlamps in foggy conditions.

[0002] It is an object of the present invention to provide a system for automatically activating the headlamps when the vehicle is operating in foggy conditions. Background Art

[0003] Existing vehicles typically have various forms of automatic headlamp activation systems, although these are typically limited to activating the headlamps when the measured external light intensity is below a predefined threshold level, and subsequently deactivating the headlamps when the measured light intensity exceeds that threshold.

[0004] Additionally, many vehicles are configured to allow automatic activation of the headlights during heavy rain. Many such vehicles are equipped with sensors to determine the amount of rain on the vehicle's windshield and are configured to activate the windshield wipers accordingly. These vehicles may be configured to automatically activate the headlights after the windshield wipers reach a "continuous" operating mode.

[0005] While these features can be used to maintain appropriate vehicle lighting levels in certain weather conditions, they can be problematic when the vehicle is operating in fog, smog or mist conditions. In foggy conditions, although visibility may be significantly reduced, the presence of airborne water droplets means that light intensity remains relatively high. Therefore, a vehicle that relies solely on light intensity measurements to operate automatic headlamps will not cause the headlamps to turn on in foggy conditions, potentially resulting in a dangerous driving situation.

[0006] As a result, drivers of existing vehicles must manually activate the headlights when they become aware of foggy conditions, and because automatic lighting is prevalent in modern vehicles, drivers may mistakenly rely on the automatic system to activate the headlights, potentially resulting in dangerous driving situations.

[0007] Existing systems attempt to provide methods for automatically activating various vehicle components when fog conditions are detected. For example, US2014 / 198213 describes a system for detecting fog conditions through direct imaging, and using this detection to signal that one or more vehicle components (i.e., operating lights) should be activated. However, the use of direct imaging through cameras mounted on the vehicle has been found to be inaccurate when attempting to determine whether fog conditions exist. Specifically, these direct imaging systems can have problems when the vehicle is operating in low light environments. In addition, direct imaging cameras are prone to calibration issues, which can lead to an erroneous assessment of actual weather conditions in the vicinity of the vehicle. Summary of the invention

[0008] The present invention seeks to address problems associated with prior systems by providing a vehicle lighting system that is able to more accurately determine whether a vehicle is operating in foggy conditions and automatically activate the vehicle headlamps.

BRIEF DESCRIPTION OF THE DRAWINGS

[0036] By way of example only, specific embodiments of the present invention will now be described with reference to the accompanying drawings, in which:

[0037] Figure 1 is a schematic diagram of a first embodiment of a vehicle lighting system.

[0038] Figure 2 is a schematic diagram of a second embodiment of a vehicle lighting system.

[0039] Figure 3 is a schematic diagram of a third embodiment of a vehicle lighting system. DETAILED DESCRIPTION

[0040] First reference Figure 1 , a vehicle lighting system 100 of a vehicle includes a computer system 102 that is in operable communication with a vehicle lighting control unit 104 .

[0041] The vehicle lighting control unit 104 is configured to activate and deactivate the headlamp control system 106 and additional vehicle lighting systems, which may include fog lights, tail lights, brake lights, backup lights, and / or indicator light control systems (not shown), as appropriate.

[0042] The computer system 102 is in operative communication with a relative humidity measuring member in the form of a detector 108, wherein the detector 108 is a relative humidity detector comprising a conventional electronic resistance hygrometer and is configured to measure the relative air humidity outside the vehicle. The computer system 102 is also in communication with a temperature sensor 110, a light intensity sensor 112 (which is configured to measure the intensity of light incident on the vehicle), and a geographic location monitoring device 114 (which is configured to monitor and record the geographic location of the vehicle). The geographic location monitoring device 114 comprises a conventional GPS tracking device.

[0043] The computer system 102 is configured to receive and store in its internal memory data from the relative humidity detector 108, the temperature sensor 110, the light intensity sensor 112, and the geographic location monitoring device 114. In operation, the computer system 102 stores measured relative humidity values, measured outside temperature values, measured light intensity incident on the vehicle, and the geographic location and time at which these measurements were made. The computer system 102 is preferably configured to receive and store continuous data entries at time intervals predetermined by the vehicle user or manufacturer.

[0044] Relative humidity detector 108 and temperature sensor 110 are located in the housing of the vehicle rearview mirror to accurately measure the relative air humidity and air temperature outside the vehicle. However, it is conceivable that relative humidity detector 108 and temperature sensor 110 can be located at any suitable position outside the vehicle.

[0045] The computer system 102 is configured to analyze the data received from the relative humidity detector 108 to determine a relative air humidity value outside the vehicle. The measured relative air humidity value is compared to a predetermined threshold relative humidity value that may be defined by a user or manufacturer to determine whether fog, smoke, or mist is present in the vicinity of the vehicle. If it is determined that the measured relative air humidity value is greater than the predetermined threshold, the computer system 102 will determine the state of the headlight system 106 (i.e., activated or deactivated). If the headlight system 106 is observed to be deactivated, the computer system 102 is configured to send a signal to the vehicle lighting control unit 104 to activate the headlight system 106. If the headlight system 106 is observed to be already activated (e.g., in a low light setting), the computer system 102 will not send a signal to the vehicle lighting control unit 104.

[0046] In the event that it is determined that the measured relative air humidity value is below a predetermined threshold, the computer system will again determine the state of the headlight system 106. If it is observed that the headlight system 106 has been deactivated, the computer system 102 will not send a signal to the vehicle lighting control unit 104. In the event that it is observed that the headlight system 106 has been activated, the computer system 102 will analyze the data received from the light intensity sensor 112 to determine the external light intensity. If it is determined that the light intensity is below a predetermined threshold (i.e., the vehicle is operating in a low light setting), the computer system 102 will not send a signal to the vehicle lighting control unit 104 to deactivate the headlight system 106. If it is determined that the light intensity is greater than a predetermined threshold, the computer system 102 is configured to send a signal to the vehicle lighting control unit 104 to deactivate the headlight system 106.

[0047] The vehicle lighting system 100 also includes an internal control unit 116 that is in operative communication with the computer system 102 and the vehicle lighting control unit 104. The internal control unit 116 includes conventional vehicle user controls, including a steering wheel, pedals, a gear lever, light and windshield wiper controls, and any other suitable controls. The internal control unit 116 also includes an instrument panel 118 and an interactive display unit 120 that are configured to provide status information to the user related to various driving parameters (e.g., vehicle speed, light status, and current vehicle position).

[0048] The internal control unit 116 is configured to allow a user to manually activate or deactivate various vehicle lights, including the headlight system 106 , via the vehicle lighting control unit 104 .

[0049] In a second embodiment of the present invention, Figure 2 As shown, the vehicle lighting system 100 also includes an external data management system 122 in operable communication with the computer system 102. The external data management system 122 is configured to receive and store data from the computer system 102, and in turn, the computer system is configured to receive and store data sent from the external data management system 122.

[0050] The external data management system 122 is configured to send a weather map to the computer system 102, wherein the weather map indicates one or more geographic areas where predetermined weather conditions have been observed. For example, the external data management system 122 may be configured to send a weather map to the computer system 102 that indicates one or more geographic areas where fog, smog, or mist has been observed. The weather map sent by the external data management system 122 is stored in the internal memory of the computer system 102. The external data management system 122 is configured to periodically send updated weather maps to the computer system 102, wherein the time interval between consecutive map updates is defined by a user or manufacturer.

[0051] In the present embodiment, the external data management system 122 is configured to obtain weather maps from the external weather data source 124. In operation, the external data management system 122 may generate weather maps using conventional computer programs from raw data received from the external weather data source 124, or the external data management system may receive and store weather maps created by the external weather data source 124 itself.

[0052] Computer system 102 is configured to compare geographic location data received from geographic location monitoring device 114 to stored weather maps to determine whether the vehicle location is within a defined geographic area.

[0053] In response to determining that the vehicle is within a defined geographic area (eg, an area experiencing foggy conditions), the computer system 102 sends a signal to the vehicle lighting control unit 104 to activate the headlamp system 106 .

[0054] As each new data input is received from the geographic location monitoring device 122, the computer system 102 compares the received location data to the most recent weather map stored on the system 102 to determine whether the vehicle is still within the defined geographic area, or whether the vehicle has left the defined geographic area. If the computer system 102 determines that the vehicle remains within the defined geographic area, no further signals are sent to the vehicle lighting control unit 104, and the headlight system 106 remains activated. If the computer system 102 determines that the vehicle has left the defined geographic area, the computer system 102 will analyze the data received from the light intensity sensor 112 to determine the external light intensity. If it is determined that the light intensity is below a predetermined threshold (i.e., the vehicle is operating in a low light setting), the computer system 102 will not send a signal to the vehicle lighting control unit 104 to deactivate the headlight system 106. If it is determined that the light intensity is greater than the predetermined threshold, the computer system 102 is configured to send a signal to the vehicle lighting control unit 104 to deactivate the headlight system 106.

[0055] In operation, the computer system 102 will determine whether the vehicle is within a defined geographic area by utilizing the raw latitude and longitude data and a suitable algorithm (eg, a conventional even-odd intersection algorithm or a winding algorithm).

[0056] In a third embodiment of the present invention, Figure 3 As shown, the external data management system 122 is in communication with the computer system 102 of the vehicle as the primary computer system 102. The external data management system 122 is additionally in communication with one or more auxiliary computer systems 102a-102n of the auxiliary vehicles. The auxiliary computer systems 102a-102n are substantially identical to the primary computer system 102, each of which is in operable communication with its respective relative humidity detector 108a-108n, temperature sensor 110a-110n, light intensity sensor 112a-112n, and geographic location monitoring device 114a-114n (not shown herein), and is configured to receive and store data from its respective relative humidity detector 108a-108n, temperature sensor 110a-110n, light intensity sensor 112a-112n, and geographic location monitoring device 114a-114n.

[0057] The external data management system 122 is configured to analyze data received from the primary computer system 102 and the secondary computer systems 102a-102n to generate a map including one or more geographic areas where defined weather conditions (eg, fog, smog, or mist) have been recorded.

[0058] In operation, the external data management system 122 is configured to generate a weather map indicating one or more areas in which fog has been detected by plotting on the map a series of location points where one or more of the primary computer system 102 and the secondary computer systems 102a-102n have indicated that relative air humidity has exceeded a predetermined threshold. The external data management system 122 is configured to plot and periodically update the one or more weather areas on the weather map using the received data using conventional computer programs.

[0059] Specifically, the external data management system 122 is configured to utilize the received latitude and longitude data to create one or more weather region boundaries on a weather map indicating the extent of the geographic area where a given weather condition is recorded (ie, fog, smog, or mist boundaries).

[0060] The weather map is sent to the primary computer system 102 and the auxiliary computer systems 102a-102n by the external data management system 122, where the weather map is received and stored in the system internal memory. The external data management system 122 is configured to periodically send updated weather maps to the primary computer system 102 and the auxiliary computer systems 102a-102n, where the time interval between consecutive map updates is defined by the user or the manufacturer.

[0061] The host computer system 102 is configured to compare the geographic location data received from its geographic location monitoring device 114 with stored weather maps to determine whether the vehicle location is within a defined geographic area.

[0062] In response to determining that the vehicle is within a defined geographic area (eg, an area experiencing foggy conditions), the host computer system 102 sends a signal to the vehicle lighting control unit 104 to activate the headlamp system 106 .

[0063] As each new data input is received from the geographic location monitoring device, the host computer system 102 compares the received location data to the most recent weather map stored on the system 102 to determine whether the vehicle is still within the defined geographic area, or whether the vehicle has left the defined geographic area. If the host computer system 102 determines that the vehicle remains within the defined geographic area, no further signals are sent to the vehicle lighting control unit 104, and the headlight system 106 remains activated. If the host computer system 102 determines that the vehicle has left the defined geographic area, the host computer system 102 will analyze the data received from the light intensity sensor 112 to determine the external light intensity. If the light intensity is determined to be below a predetermined threshold (i.e., the vehicle is operating in a low light setting), the host computer system 102 will not send a signal to the vehicle lighting control unit 104 to deactivate the headlight system 106. If the light intensity is determined to be greater than the predetermined threshold, the host computer system 102 is configured to send a signal to the vehicle lighting control unit 104 to deactivate the headlight system 106.

[0064] In operation, the host computer system 102 will determine whether the vehicle is within a defined geographic area by utilizing the raw latitude and longitude data and a suitable algorithm (eg, a conventional even-odd intersection algorithm or a winding algorithm).

[0065] In each of the described embodiments, the computer system is configured to determine the presence of fog and smoke conditions.

[0066] Meteorological organizations generally define fog as a weather phenomenon that occurs when the difference between the outside air temperature and the dew point temperature is less than 2.5 degrees Celsius and the relative humidity of the air reaches (or approaches) 100%. In order to ensure the correct operation of the vehicle lighting system 100, the computer system 102 determines that fog exists when the measured relative humidity exceeds a threshold value of 98% relative humidity.

[0067] The present invention is also capable of determining if smoke is present in the vicinity of the vehicle. In some cases, the exterior light intensity will be below a defined threshold level at which the headlights will automatically activate due to smoke, although this is not always the case. To ensure that the headlights are activated when needed, the computer system 102 determines that smoke is present when the measured exterior light intensity reaches a predetermined threshold of 105% and the measured relative humidity exceeds a predetermined threshold of 97%.

[0068] In addition, the vehicle lighting system 100 of each described embodiment also includes a noise generator 126, which is configured to generate a continuous audible tone or sound when the computer system 102 determines that fog or smog conditions exist. The computer system 102 is configured to activate the noise generator 126 when it is determined that the vehicle is running in fog conditions (by determining the relative humidity). When sending a signal to activate the headlamp system 106 in fog conditions, the computer system 102 is also configured to send a signal to activate the noise generator 126. The provision of a noise generator is particularly useful for electric vehicles or hybrid vehicles operating in fog conditions, because the presence of fog causes the attenuation of natural noise generated by the vehicle to be small. The increased noise level due to the noise generator 126 can ensure that pedestrians are alerted to the presence of the vehicle.

[0069] In each of the embodiments described herein, the vehicle may be a conventional user-operated vehicle, or the vehicle may be an autonomous or unmanned vehicle.

[0070] In the case of a normal user operating the vehicle, the user will typically have access to all of the control range of the internal control unit 116. Thus, the user will be allowed to manually override the automatic activation or deactivation of any lighting control system of the vehicle lighting control unit 104. If the computer system 102 determines that the vehicle is operating in foggy conditions, and the user has manually overridden the command to automatically activate the headlamp system 106, the computer system is additionally configured to communicate with the internal control unit 116 to activate a visual or audible warning signal, wherein the visual signal may include a warning light displayed on the instrument panel 118 and / or an audible or visual message displayed on the interactive display unit 120.

[0071] It is contemplated that alternative methods of determining relative humidity may be applied to the present invention, depending on the needs of the user or manufacturer. Various measurement means for determining relative humidity are known in the art, such as by capacitive hygrometers, resistive hygrometers, thermal hygrometers, or gravimetric hygrometers, and may be used interchangeably in the present vehicle lighting system 100.

[0072] Additionally, the relative humidity measurement system may alternatively include various sensors or detectors that allow the relative air humidity to be measured indirectly through a suitable formula. For example, the relative humidity measurement means may include a sensor for determining the dry bulb temperature, a barometer for determining the atmospheric pressure, and an altimeter for determining the altitude, wherein the altimeter may alternatively be built into the vehicle's geographic location monitoring device. The measured parameters may be used in a suitable formula to calculate the relative humidity value. It is conceivable that the relative humidity measurement means may include any suitable sensor or detector that allows the relative humidity calculation to be achieved.

[0073] Furthermore, although thresholds of 98% and 97% relative air humidity are preferred for the detection of fog and smoke conditions, it is envisioned that the exact thresholds may vary, depending on the specific requirements of the manufacturer and / or user.

[0074] It is also contemplated that various other vehicle lights may be activated and deactivated in addition to the headlight system 106. For example, the vehicle fog lights (if not already activated) may be configured to activate via a signal from the computer system 102 when fog is detected.

[0075] Furthermore, it is envisioned that the interactive display unit 120 may be configured to display a weather map stored on the computer system 102 in addition to or in lieu of a conventional satellite navigation map. This provides the user with a visual indication of the weather area observed in the vicinity of the vehicle.

[0076] It is conceivable that the first embodiment of the invention may be used in conjunction with the second and third embodiments in that the standard method of operation is the relative humidity determined by the vehicle's own relative humidity detector 108, however, operation as a result of determining the vehicle's geographic location may supplement that operation or may be used in the event that the vehicle's relative humidity detector 108 fails or is miscalibrated.

[0077] Various other changes and modifications may be made to the present invention without departing from the scope of the invention.
