This invention refers to a control and signaling device developed for use inside automotive vehicles, preferably while fastened onto the user's body. This invention is classified under the “electronics” sector.
The Patent Application BR0500758-5 of Sep. 3, 2005 and the Application priority with protocol No. 015060000986 of Sep. 2, 2006 at the INPI headquarters in Curitiba-PR Brazil, of the same applicant and whose inner priority is herein claimed. Said addition just adds some more technical innovations, which do not change the invention concept.
The technological evolution and innovation in the automotive field, has brought comfort, safety, entertainment, more freedom and resources for both the driver and passengers of automotive vehicles. The complexity of mechanical elements, especially electronic ones, is forever increasing, yet the simplicity added together with the benefits of use is fundamental characteristics for the users.
In most state of the art automobiles, resources and functionalities such as: digital audio and video, satellite navigation systems, on-board computers, electronic adjustable seats, automatic transmission, etc. are included. The great challenge however, seems to be combining the access to all functionalities of the vehicle in one practical and simple control system, thus in turn making the user's interaction easier. Generally, the audio, video, air conditioner and on-board computer controls are located in the central panel, which in turn, makes it necessary for the user to reach out and focus their attention on the controls, causing both a distraction and a risk by having to take their eyes off the road for a moment. Some of these controls are placed on the steering wheel, however they may hinder driving in certain situations. Even though touch screen monitors represent an interesting option, they are placed on the central panel of the vehicle or next to the gear stick, also distracting the driver's attention.
The idea of the current invention is to concentrate the main controls of the vehicle on an easy to access operating device, which is preferably fastened onto the user's body, for instance, having the device fastened onto a user's leg, which enables the user to operate the on-board computer, entertainment system, air conditioner, engine variables, electronic system, among others, and also able to provide signaling to the user, who detects the vibration produced by the device, referred to any warning or a driving aid, depending on the situation. This way the electronic device of the present invention, preferably fastened onto the user's body, prevents lapses of attention, which could be potentially hazardous to both the driver and passengers, as well as permitting practical, comfortable, safe and intelligent interaction with the automobile's electronic systems. Having the option of attaching this device onto one's body, the person in the passenger seat is able to act as a navigator, performing secondary electronic, electrical and mechanical functional tasks. Performed on a daily basis, this would be an unprecedented act in the history of automotive vehicles. Therefore, the vehicle would be controlled by the driver and the passenger (navigator), which would result in a more inclusive control, and also guarantee the safety of the occupants, other vehicles and pedestrians as well.
The purpose of this invention is to provide an automotive vehicle with an electronic device, to be fastened onto the driver's or passenger's body, enabling to control functions and resources of the vehicle, in addition to acting as an signaling of events including an alarm, speed limits, special signals, and the like. Other applications such as the interaction with instrumental and musical devices are also aimed at. It is hoped that the present invention might prevent lapses of attention in situations where the driver wishes to interact with the electronic systems of the vehicle, and make the act of driving and other integrated systems simple, accurate and comfortable. Besides producing easy to identify low noise warnings, the device of this invention may act as a driving aid.
The electronic device is based on the idea of having the main controls of an automotive vehicle 1 on a remote device 8, preferably fastened onto the user's body, aiming towards making interaction with vehicle's systems easier. The remote device 8 is presented in seven modalities 55,65,70,90,106,150,180,210,228 which aim at including all the spectrums of use while attending to the needs of the user. This device has an anatomical shape, providing the user with short cut keys 169,174,172,168, commands, spin disc and roll 205,225, pad 177, alphanumerical keyboard 76, display 32, among other elements. The commands are sent from the remote device 8, through its communication system 29, to the on-board computer 15, portable sound system 13, video game 14 and/or cellular phone 6, which are compatible with the communication system of the device 29. In the same way, information and commands can be sent by the on-board computer 15, and by other compatible devices.
The electronic device referred can be used to control several systems and devices of the vehicle such as the entertainment system 2, which may comprise a CD player, a radio (analog, digital or via satellite), a DVD player, or any other audio or video device. It can also be used to interact with the navigation system of the vehicle 12, also known as GPS (Global System Positioning), aiding in the navigation of maps, routes, selection and marks in general. Controlling specific variables of the vehicle is also possible through the on-board computer 15. In this case, the access is restricted to the driver, since some of those functions may constitute risk to safe driving. Such access is obtained through a password which must be typed on the alphanumerical keyboard 76. That also means that while the other occupants of the vehicle might still make use of the device, they will only have access to specific functions. The remote device 8 can act in the following elements of the vehicle: air conditioner, head lights, brake lights, turn signals, windshield wiper, cruise control, power windows/locks, gear shifting (in semi-automatic transmission), acceleration/traction control, among other controllable elements of the vehicle.
Another innovative functional characteristic of the device is its capability of vibration signaling. This kind of signaling enables the user to feel the vibrations produced by the device on the part of the body where it is attached. The advantages are obvious, compared to the sound signal systems found in most vehicles, which are either unnecessary or unpleasant to the other occupants of the vehicle, and should only concern the driver. Vibration signals may function as a warning system when an abnormal condition is detected, or in the case of danger, for instance, as in a sudden drop of tire pressure, lack of fuel, low engine oil levels, critical problems in a particular device, etc. Each type of signal can be configured in frequency, amplitude, and/or shape of mechanical wave, in a way that the detected signals can be easily distinguished by the user. A call to the user of the cellular phone 6 may produce a vibration signal on the remote device 8, through direct communication with the device 8 or though the vehicle's on-board computer 15. The device's alphanumerical keyboard 76 also allows the user make phone calls using his cellular phone 6, yet another innovation of the electronic device of this invention.
Another important feature which the vibration signaling 24 provides is the capability of assisting the driver in parking his car. Back up sensors, installed in the bumpers, can transmit the relative proximity of objects to the device 8. This information is then interpreted, and a vibration is produced according to the proximity, proportionally to amplitude, frequency, and/or interval between the mechanical vibrations emitted. This way, the driver can have an idea of the distance between the vehicles, thus making parking easier.
Vibration signaling 24 may also be useful to indicate that a particular speed limit has been reached. Once the remote device 8 interacts with the on-board computer 15, the information relating to the speed of the vehicle 1 can be sent to the device 8. Therefore, the remote device 8 is also capable of working as a speed controller, constantly monitoring the speed of the vehicle 1, informing through a vibration signal that a pre-set limit has been reached or exceeded. Let us suppose, for example, that the speed limit on a highway is 110 km/h (kilometers per hour). The driver sets this limit on the remote device 8. When the vehicle 1 nears this mark, the device 8 starts, gradually, producing vibrations, which can be felt by the user. As the speed limit is reached or exceeded, the vibrations become more intense. Several forms of vibration signaling 24 may be used, with the possibility of controlling its intensity, frequency and/or duration.
The adjustable elastic strap 82, which is part of the device 8, makes it possible for the user to fasten and adjust it to their body in the most suitable way. It comes with Velcro™ strips or adhesive portions 83,84,85,86. Another suggested kind of strap is comprised of an adjustable retractable elastic strap 251,252, which retracts automatically into the device 250, making it possible to fit the device 8,250 in a support 258 located inside the vehicle.

The device acts as an extension of the commands offered by the electronic system or the on-board computer of an automotive vehicle. Assuming a vehicle with several kinds of features, as shown in
Keyboards 4 for entering data are arranged on the panel of the vehicle, and also on the steering wheel, and dials or displays 3 are located in suitable places. The on-board computer usually acts on the command of the electrical system 5, which is comprised of the essential devices of visual signaling, lighting, ignition, alarm, windshield wipers, among others. The cruise control and the access to engine variables make it demand that the on-board computer and/or other subsystems should control and obtain information from the engine 11, as well as the sensors 10 of the air conditioning, alarm, doors, etc. The control of the electrical and mechanical elements such as air conditioning valves, power door locks, power seats, among others, can be performed through actuators 9.
Digital entertainment technology has taken resources which were once used only at home or in computers, to automotive vehicles, for instance, DVD players, MP3 players, 3D surround audio systems, next generation video games, besides allowing audio and video to be picked up anywhere inside the vehicle. Satellite navigation systems (GPS—Global Positioning System), are also becoming more prominent. Thus, the on-board computer 15 may interact with the automotive entertainment system 2, and the vehicle navigation system 12, making it even easier to operate them. The user's cellular phone 6 may also be controlled by the on-board computer 15, through a compatible communication system 7, making use of the vehicle sound system so that the user may be able to make or receive phone calls, listen and talk at a distance through this device.
The remote device 8, object of the present invention, communicates with the on-board computer of the vehicle 15, through the communication system 7, making it possible to control, receive commands and/or information, indirectly, from the entertainment system 2, navigation system 12, engine parameters 11, actuators 9, electrical system 5, and cellular phone. It is important to point out that the cellular phone 6 can be operated and/or send commands or information directly to the remote device 8, as well as to a portable sound system 13, or a video game 14, which also send audio/video signals to the inputs of the entertainment system of the vehicle 2.
Although there is a display on the remote device 8, the user may prefer only to handle this device and visualize the correspondent events on graphic display or monitor located on the instrument panel. Head-up displays consist of a system which projects a visual screen on the windshield of the vehicle, typically on the central or lower left part, making it easier to visualize keys, windows, menus and other graphic objects that may be projected. Through a Head-up display the driver can visualize a graphic screen in an appropriate place on the windshield, and perform selections, menu browsing, adjustments, among other options, making use of the remote device 8. Therefore, the driver or passenger will handle the remote device 8 fastened onto their body and visualize the display with the commands on the windshield, what allows them to keep focused on the traffic and also makes it easier to move the hand, which is dealing with the device, to the steering wheel, gear shift or hand brake.
The microprocessor 30 controls all the internal devices and circuits. It directly accesses the following kinds of memories: Flash memory 22, which stores the embedded software or the system's firmware and data; RAM (Random Access Memory) 21, which temporally stores processing data. The readout of all press-keys of the keyboard 26 is carried out by the microprocessor 30, which also controls the display 32. Through the keys found in the device, it is possible to select functions, adjust parameters, directly access the systems of the vehicle, among other possibilities which will be dealt with later on. The display 32 shows the user the most relevant information, such as: entertainment system 2 audio and video adjustments, graphic equalizer, air conditioning parameters, fuel level, menus, submenus, symbols, adjust options, the status of several elements of the vehicle that can be monitored, and is also capable of acting as a display extension for a cellular phone 6, an on-board computer 15, a GPS 12, a portable sound system 13, and a video game 14.
The scroll sensors 28 are associated to a wheel called scroll 75, similar to the ones used in computer mouse. Those sensors, preferably optical, can detect the rotation steps performed on this disc/wheel, helping in the selection of functions, icons, symbols, intensity adjustment of several types of parameters, and in the browsing of menus and submenus. LEDs (light-emitting diodes) 31 are placed below the semitransparent or transparent surface of the keys and of the scroll wheel 75, in order to provide luminous indication to the user, in reference to the action that needs to be taken, a key to be pressed, an abnormal condition alert, indicating when a parameter has reached its maximum or minimum, among other possible functionalities.
The vibratory signaling 24 consists of a component, attached to the structure of the device 8,20, with the purpose of producing mechanical vibrations on its structure, which will be transmitted to the user when in contact with their body. The element which is responsible for emitting mechanical vibrations may be a micromotor, a solenoid, or any other eletromechanical device capable of producing proper mechanical vibrations to attract the user's attention. The vibratory signaling 24 is controlled by the microprocessor 30, which acts on the control of the intensity, frequency and duration of the emitted vibrations. Through this resource, it is possible to provide the user with vibratory signals, such as any kind of alert, indication of functions, signaling a phone call, text message or photograph received on the cellular phone, among other possible kinds of signaling and indication. This innovative idea represents an alternative mean for the user of the remote device 8,20 perceive this kind of indication, without disturbing the other occupants of the vehicle with unwanted sound or luminous signals.
The communication between the remote device 8,20 and the vehicle 1 is performed through the communication system 29, which is compatible with the communication system of the vehicle 7. This system 29 allows for data communication in a bidirectional way (two-way), which may be done through radio frequency (RF), ultra sound, infrared light and/or electric wiring/cabling. In addition to that, communication system 29 also establishes communication with other compatible devices such as cellular phone 6, portable sound system 13, or video game 14. If the on-board computer 15 is connected to a wireless communication system 7, with Bluetooth™ technology (RF), the remote device 8,20 with compatible system will be able to act on the functions and resources made available by the vehicle 1.
The display 32 may be linked to the pad 177, showing keys or selection options. It can recognize the touch as it aggregates the pad 177 right under its surface just like a touch screen display. In case display 32 is not linked to the pad 177, leds 44 are arranged under the transparent or semitransparent surface of pad 177 providing visual indication regarding places to touch, signaling, visual alarms, and also form geometric figures such as arrows, circles, rectangles, symbols, icons, characters, numbers, among other figures. The information in order to command the lighting of the leds 44, as well as the control of the vibratory signaling 24 and other devices, comes from the vehicle's on-board computer 15, or the compatible equipment connected by means of the communication system 29.
The fifth and sixth modalities of the remote device 50 are shown in detail by the block diagram of
The third modality 60 stands out for its audio adjustment sliding keys 62 which may consist of resistive potentiometers, optical displacement sensors, or any other kind of sliding adjustment. The microprocessor 30 performs the analog or digital readout of these devices, resulting in a particular value in the adjustment scale, being sent to the entertainment system of the vehicle 2, which interprets and carries out the parameter adjustment. Sounds coming from the entertainment system 2 can also be sent to the remote device 60, through the communication system 29, so that the user is able to listen to them through the use of headphones which are connected to the device. The data received through the communication system 29, referred to the sounds received by the remote device 60, is decoded by the microprocessor 30, which sends it to the digital-to-analog converter or D/A converter 63. The analog signals resulting from the D/A converter 63 pass through an active filter 64, which eliminates noise and limits the output frequency range, and are amplified by the audio amplifier 65. The entertainment system 2 signal is then recomposed in the remote device 60 and sent to the external headphones. The leds 61 indicate the audio channels in such a way, so that when a led is lit up, the respective channel is on.
The seventh modality of the remote device 55 also allows for sounds to be received, processed and sent to the entertainment system 2 or another sound system as the block diagram of
The remote device 55 features a Digital Signal Processor (DSP) 68 which can mix sounds, perform several kinds of digital audio processing (filter, distortions, equalization, mixing, instrumental sound production, sound effects, etc.) and interact with peripherals. Two types of memory are associated to the DSP 68: RAM memory 53, which stores temporary data referring to variables, sounds, etc. and; Flash Memory 54, which stores the firmware or the embedded software so that this device can perform its tasks. Songs or sound samples may be coded, zipped, or encrypted. In case the DSP 68 cannot perform the processing of this kind of data, the decoder 57 has resources to decode, unzip, or decrypt data, resulting in intelligible data to the DSP 68. As with the synthesizer 58, it works on the production of instrumental sounds (percussive, keyboard, string or wind), from musical parameter input, working with the DSP 68.
The flash memory 59 is intended to store songs, sounds, samples, files, among other information which can be accessed through the DSP 68 or the microprocessor 30. The computer interface 66 offers a communication port, compatible to any computer, enabling access to all the resources of the device, data reading and writing in the flash memory 59, besides facilitating firmware update. The device's memory capacity can be expanded through a memory card. In this case, the memory card interface 67 provides connection means to several kinds of cards, permitting the device to perform all the necessary functions.
A selected sound source or the resulting sound of the remote device 55 can be heard in external headphones. In that case, the digitalized sound is turned into corresponding analog signals through the D/A converter 63, passing through filter circuit and amplifier 69, which perform the signal conditioning in order to stimulate external headphones, via headphones connector 132.
The microprocessor 30, which also interacts with the DSP 68, is responsible for the controlling and reading of peripherals, such as sliding keys 62, vibratorion signaling 24, keyboard 26, display 32, and leds 61, containing an associated flash memory 56 by way of storing the firmware of this subsystem. The communication system 29; volume control on the active filter and amplifier 69; and also memory card and computer interfaces 67,66, can be controlled by the microprocessor 30 as well.

Another way of attaching the second modality of the device 90 to the adjustable elastic strap 82 is shown in
The MENU key 143 and browsing arrows 144,142 permit the access and browsing in menus, submenus, icons, sound adjustments, audio function operation, besides granting access to the vehicle's systems 12,5,2, etc. The channels 126,127,128,129,130 may also be used to make adjustments in the air conditioning, electric system 5, engine 11, GPS 12, among others. All the possible visualizations for the user are shown on the graphic display 32. The ON/OFF key 131 turns the device 120 on or off, being that there is a visual indication through the led 140 next to this key 131. The headphone connector 132 makes it possible for the user to connect an external headphone in order to monitor the processed or adjusted sounds.
The output sound, referring to one of the input channels or to the mixing of two or more channels, is selected through the Output Select key 137. The output channels 138,133,134 comprise sliding adjustments of intensity 125, and leds 124 for the selection indication. The AUX1133, and AUX2134 channels select two output options which may be formed by the selection of input channels 126,127,128,129,130 or any audio source. The RADIO channel 139 controls the audio volume input referred to the entertainment system 2, be it from the radio, CD player, MP3, or DVD player, which will come out of the remote device 120. The MIXER channel 138 corresponds to the intensity adjustment of a personalized output, which refers to the mixing of two or more audio signals. At last, the resulting audio signal or from a selected audio source can be recorded through the REC key 145. In the seventh modality of the remote device 55, the recording is carried out digitally in the form of data which are stored in the Flash memory 59, or in a memory card, with or without codification, operation of zipping and/or cryptography of this data.
