Description

METHOD AND SYSTEM FOR REDUCING DISTRACTION DURING DRIVING Field of the Invention
The present invention relates to a method and system for selectively restricting the operation of vehicular comfort devices during driving. Background of the Invention
It has been shown that use of comfort devices such as mobile (cellular) phones, car radio receiver or other audio entertainment devices, including navigation systems and air conditioning or climate controls while driving, reflects a degree of distraction that may cause accidents. For this reason, permanent installations or phone holders that permit hands-free conversation are required by law in some countries. It was however, further determined that even with such a system installed, the duration of placing the call involved with manual keystrokes and watching the display, may present even greater distraction than holding the phone. The importance of avoiding such distractions becomes more critical during high speed driving or difficult road conditions, where only a second or two of inattention to the road, may lead to a fatal accident.
Voice recognition user interfaces for use with portable phones aim to eliminate the need for dialing numbers by interpreting verbal strings into an automatic dialing sequence. Such systems, with some variants, are commercially available. The performance of voice recognition systems, however, is influenced by several factors such as the environment, the speaking rate and clarity of the speaker, and the context or grammar being used by the system. As a result, speaking to the device and receiving its feedback also requires much attention.
U.S. Patent No. 7,007,118 teaches a central computerized control system for integrating car electronic devices into one standard human interface, easing their use. The proposed integration system, however, is not defined as a safety system, or as a means for improving the driver's attention during high speed driving. Consequently, a need still exists for a device that permits the driver's full concentration, particularly during high speed or difficult driving conditions. Summary of the Invention
It is therefore a broad object of the present invention to provide a method and a system, for eliminating unnecessary distractions during high speed driving or other hazardous conditions, such as foggy or rainy weather, a wet road, darkness or direct sun dazzle.
It is another object of the present invention to provide a microprocessor-based control system, operative according to the defined method, wired or wirelessly coupled to at least one sensor from the list of: speed sensor, fog sensor, rain detector, dazzle detector, darkness sensor, for collecting the car driving conditions, constantly comparing the collected car driving conditions to memory stored corresponding values, announcing and disabling, at least partially, at least one of the comfort devices functionality usage, when at least one of the collected driving conditions is detected to be greater than its preset value, by means of a wired or wireless connection to the device.
In accordance with the present invention there is provided a method for reducing distractions when operating comfort devices during predetermined driving conditions in a motor vehicle, including the steps of: a) collecting information of at least one drive condition; b) detecting when at least one of the collected information drive conditions is above a preset value, and c) temporarily blocking, at least partially, at least one of the installed comfort device's functionality until driving conditions change.
The invention further provides a microprocessor-based control system, coupled to at least one sensor for collecting car driving conditions, comprising: constantly comparing the collected car driving conditions to memory stored corresponding values, and disabling, at least partially, at least one of the comfort device's functionality, when at least one of the collected drive conditions is detected to be greater than its corresponding preset value, by means of wired or wireless connection to the comfort device. In particular, the described method step c) will block at least one of the car installed cellular phone functions, including: SMS editing, number dialing, short key dialing, send key, all keys (key lock). Brief Description of the Drawings
The invention will now be described in connection with certain preferred embodiments with reference to the following illustrative figures so that it may be more fully understood.
With specific reference now to the figures in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of the preferred embodiments of the present invention only, and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the invention. In this regard, no attempt is made to show structural details of the invention in more detail than is necessary for a fundamental understanding of the invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the invention may be embodied in practice.
In the drawings:
Fig. 1 is a flow chart describing the method steps of the present invention;
Fig. 2 is a schematic diagram of the system components and their connectivity, according to the present invention, and
Fig. 3 is a schematic diagram of a minimal system, according to the present invention. Detailed Description
With reference to the drawings and specifically to Fig. 1, the steps of the proposed method are described. Sensor device 10 transmits speed or another vehicle condition value to a control unit 12. A preset corresponding comparative value 14 is fed to the control unit 12 by an input device 16 and stored internally in non- volatile memory module 18. The input device 16 may preferably not be available to the driver or the comparative value may be factory set into memory module 18. A comparator 20 within the control unit 12 constantly compares the sensor 10 reading and the preset value 14, stored in memory module 18. If the sensor 10 reading becomes higher than the preset value 14, an output signal 22 is activated performing sequence 24 of: preferably first informing the driver that some comfort devices will not be available due to the instant driving conditions, followed by disabling some functionality of the comfort devices 26 such as, for example, disabling the number of dialing functions of the mobile phone. When the car slows down or the relevant driving condition decreases back below the preset value 14, the output signal 22 is deactivated performing the reverse sequence 24 of: enabling the disabled comfort devices' functionality, followed by preferably informing the driver that the comfort devices 26 are available. The change of state of output signal 22 may be postponed for a short delay period, in order to avoid unnecessary device blocking during short acceleration.
The sequence 24 of operations following the output signal 22 change of state, may take different order or different steps than suggested above, for instance the controller may inform the driver about disability of some functions, only if the driver tries to activate an actually limited function. Informing the driver is preferably made by a recorded voice message, transmitted to the vehicle's audio system or to a wireless headset, if available, however, a clear LED array may optionally be used.
According to indications advertised by law regulations, or in large organizations, by the transportation manager, blocking certain functionality of the comfort devices may gradually be performed, with respect to the degree of risk involved. For example, the phone system may be related to a certain speed limit, such that, for instance, at a speed of above of 60 km/h, only number dialing will be disabled, permitting short key dialing or receiving a call; at a speed of about 80 km/h all dialing of calls will be blocked, yet allowing reply to incoming calls, and at a speed of above 100 km/h, for instance, all phone functions will be blocked.
With reference to Fig.2, the system is composed of a microprocessor-based control unit 30, having a plurality of input and output ports 32, 34. Input ports are preferably wired to several digital or analog sensors 36, such as the car speedometer. Car speed can also be calculated by reading the TDC (top dead center) sensor signal and the current drive ratio, which inputs are available on most modern cars. Other optionally installed sensors may include rain sensors, fog sensors, darkness sensors and dazzle sensors.
The output ports 34 may be of the wired or wireless type, optionally using one of the standard communication protocols such as USB, wireless LAN or BlueTooth short range wireless connectivity standards. On the device side, the function disabling the circuits may be embedded into the device, for example, the phone electronic circuits can make use of the integral phone BlueTooth wireless connectivity to receive and execute the controller's instructions. Phones without such ability may be positioned in a phone holder, preferably using a wired connection to the controller operating the phone through its data connector. In both cases, while the phone is operative, the driver will be able to use the wireless headset, equipped with the phone or use the vehicle's audio loudspeakers, as is common practice with fixed installations.
While the above-described embodiment makes use of the idea behind the proposed invention, to an extent, it is still possible to utilize the embodiment of the present invention as shown in Fig. 3, to take control only over a cellular phone 50 with reference to only vehicle speed. Such a control system can be embedded into the phone electronic circuits, requiring one interface to the vehicle's speed sensor, or preferably to an external speed detecting system, such as a GPS. Readings of the speed sensor could be wired to the phone holder 58 and fed to the phone through its data connector, or if the phone is equipped with wireless connectivity, such as the BlueTooth standard, the speed sensor 56 may transmit the speed value directly to the phone 50. The phone's internal controller will permit operation functions according to a corresponding speed value. In particular, the controller may block part of the cellular phone's functions, related to risk of usage, preferably in the following order: SMS editing (high risk), number dialing, short key dialing, send key, all keys (key lock). Alternatively, any ground position system or a like system which includes provision of speed calculations and indications, built-in in a portable or stationary communication device, e.g., a telephone or cell phone, could be utilized to control the allowed operations of the telephone and cell phone in accordance with the speed detected, as described above.
Advantageously, the internal controller will be rendered functional upon placing the phone 50 in or on the phone holder 58 and its connection to an external voltage, as indicated by the broken line 60.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrated embodiments and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
