This application claims priority to Taiwanese Patent Application No. 106136180 filed on Oct. 20, 2017.
The disclosure relates to a headlamp system for a vehicle, more particularly to a headlamp system controllable by a portable electronic device.
Generally, a conventional headlamp of a vehicle is configured to emit various light beam patterns, such as a low beam pattern and a high beam pattern. However, each of the light beam patterns emitted by the conventional headlamp cannot be further adjusted by a user. Further, neither luminous intensity of light emitted by each lamp of the conventional headlamp nor orientation of the conventional headlamp is adjustable.
Therefore, an object of the disclosure is to provide a headlamp system capable of being controlled by a portable electronic device.
According to one aspect of the disclosure, a headlamp system includes a headlamp device and a machine-readable storage medium. The headlamp device is to be mounted on a vehicle and includes a light-emitting set, a control module, and a wireless communication module electrically connected to the control module. The machine-readable storage medium stores instructions that, when executed by a portable electronic device, cause the portable electronic device to display a control interface that includes a plurality of beam pattern options related respectively to a plurality of headlamp parameter sets, and, in response to user selection of one of the beam pattern options, output, to the wireless communication module, a corresponding one of the headlamp parameter sets that is related to said one of the beam pattern options. The control module is configured to, in response to receipt of the corresponding one of the headlamp parameter sets through the wireless communication module, control the light-emitting set to emit light based on the corresponding one of the headlamp parameter sets.
According to another aspect of the disclosure, a machine-readable storage medium stores instructions that, when executed by a portable electronic device, cause the portable electronic device to:
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiments with reference to the accompanying drawings, of which:
Referring to
The portable electronic device 4 includes a processor 41, storage medium 42, a communication module 43 and a display 44. In this embodiment, the portable electronic device 4 is a mobile phone (e.g., a smartphone) and can be, for example, a personal digital assistant (PDA), a tablet computer or a smart watch in other embodiments of the present disclosure. The storage medium 42 stores an application program (App) 421 which is downloaded from, for example, a cloud server (not shown). The storage medium 42 may include any non-transitory memory mechanism, such as read-only memory (ROM), random-access memory (RAM), magnetic disk storage media, optical storage media, flash memory, solid state devices (SSDs), and other storage devices and media.
Each of the wireless communication module 35 and the communication module 43 may include a short-range wireless communication module supporting a short-range wireless communication network using a wireless technology of Bluetooth® and/or Wi-Fi, etc., and a mobile communication module supporting telecommunication using Long-Term Evolution (LTE), the third generation (3G) and/or fourth generation (4G) of wireless mobile telecommunications technology, and/or the like.
The App 421 includes instructions that, when executed by the processor 41 of the portable electronic device 4, cause the processor 41 to control the display 44 to display a control interface 440. The control interface 440 includes a beam pattern selecting function 5 that includes a plurality of beam pattern options 51 related respectively to a plurality of headlamp parameter sets. In this embodiment, the display 44 includes a touchscreen. The headlamp parameter sets are related respectively to a plurality of beam patterns to be emitted by the light-emitting set 32. In this embodiment, each of the headlamp parameter sets is associated with at least one of the lamp assemblies 321.
In response to a user selection of one of the beam pattern options 51, the processor 41 outputs a corresponding one of the headlamp parameter sets that is related to said one of the beam pattern options 51 to the wireless communication module 35 of the headlamp device 3 via the communication module 43. Upon receipt of the corresponding one of the headlamp parameter sets by the wireless communication module 35, the control module 34 controls, based on the corresponding one of the headlamp parameter sets, each lamp assembly 321 that is associated with the corresponding one of the headlamp parameter sets to emit light in order to form a corresponding one of the beam patterns related to the corresponding one of the headlamp parameter sets. Note that the lamp assemblies 321 may emit light having a default luminous intensity or having a last-recorded luminous intensity.
The App 421 also includes instructions that, when executed by the processor 41 of the portable electronic device 4, cause the processor 41 to control the display 44 to display the control interface 440 to further include a luminous adjusting function 6 for adjusting luminous intensities of the lamp assemblies 321. Specifically, after one of the beam pattern options 51 is selected, the luminous adjusting function 6 of the control interface 440 includes, for each lamp assembly 321 that is associated with one of the headlamp parameter sets related to the selected one of the beam pattern options 51, a lamp-assembly option 61 related to the lamp assembly 321, and a plurality of luminous options 62 related respectively to a plurality of luminous parameter sets that are related respectively to a plurality of beam luminous intensities to be emitted by the light-emitting set 32. For example, the headlamp parameter set corresponding to the selected one of the beam pattern options 51 is associated with two lamp assemblies 321, and the luminous adjusting function 6 of the control interface 440 includes two lamp-assembly options 61 related to the two lamp assemblies 321, respectively. In response to a user selection of the lamp-assembly option 61 related to one of the two lamp assemblies 321 and one of the luminous options 62, the processor 41 outputs a corresponding one of the luminous parameter sets related to the selected one of the luminous options 62 to the wireless communication module 35 via the communication module 43 to control said one of the two lamp assemblies 321. In response to receipt of the corresponding one of the luminous parameter sets through the wireless communication module 35, the control module 34 adjusts luminous intensity of light emitted by said one of the two lamp assemblies 321 based on the corresponding one of the luminous parameter sets. That is, the selected lamp assembly 321 is controlled to emit light having one of the beam luminous intensities related to the corresponding one of the luminous parameter sets.
In one embodiment, the luminous adjusting function 6 of the control interface 440 includes a plurality of lamp-assembly options 61 related respectively to the lamp assemblies 321 of the light-emitting set 32, and a plurality of luminous options 62 related respectively to a plurality of luminous parameter sets that are related respectively to a plurality of beam luminous intensities to be emitted by the light-emitting set 32. When it is desired to adjust luminous intensity of any one of the lamp assemblies 321, one of the lamp-assembly options 61 is first selected, then one of the luminous options 62 is selected, and the processor 41 outputs the respective one of the luminous parameter sets to the wireless communication module 35 to thereby adjust luminous intensity of light outputted by the lamp assembly 321 related to the selected lamp-assembly option 61. That is to say, the luminous intensity of each of the lamp assemblies 321 can be adjusted independently as desired and the present disclosure is not limited to this respect.
The App 421 also includes instructions that, when executed by the processor 41 of the portable electronic device 4, cause the processor 41 to control the display 44 to display the control interface 440 to further include a rotation function 7 allowing user operation to set a pitch angle of a pitch rotation of the light-emitting set 32 relative to the housing 31 and a yaw angle of a yaw rotation of the light-emitting set 32 relative to the housing 31. In response to a user input related to the pitch angle and/or the yaw angle, the processor 41 outputs an angle parameter related to the user input to the wireless communication module 35 via the communication module 43. In response to receipt of the angle parameter through the wireless communication module 35, the control module 34 controls the driving module 33 to drive pitch rotation and/or yaw rotation of the light-emitting set 32 relative to the housing 31 so as to set the pitch angle and/or the yaw angle based on the angle parameter.
In this example, the rotation function 7 includes a pitch adjusting element 71 for the pitch rotation and a yaw adjusting element 72 for the yaw rotation. Each of the pitch adjusting element 71 and the yaw adjusting element 72 is, for example, a slider or a track bar allowing a user to adjust the pitch/yaw angle by moving an indicator of the slider, or a text entry box or a text field allowing a user to directly input a value of the pitch/yaw angle.
The term “processor” as used throughout the specification may refer to any device or portion of a device that processes electronic data from registers and/or memory to transform that electronic data into other electronic data. For example, the processor 41 may include, but not limited to, a single core processor, a multi-core processor, a dual-core mobile processor, a microprocessor, a microcontroller, a digital signal processor (DSP), a field-programmable gate array (FPGA), an application specific integrated circuit (ASIC), a radio-frequency integrated circuit (RFIC), etc.
To use the headlamp system of the present disclosure, the headlamp device 3 is first mounted onto a vehicle and then the user operates the portable electronic device 4 to pair the communication module 43 with the wireless communication module 35. Hereafter, the user intending to control operation of the headlamp device 3 can select a desired one of the beam patterns, adjust the luminous intensities of each (associated) lamp assembly 321 and adjust orientation of the light-emitting set 32 relative to the housing 31 through operating the control interface 440. By using the headlamp system of the present disclosure, the user is capable of controlling operation of the headlamp device 3 without replacing an electronic control unit on a vehicle and thus is relatively cost effective.
