Definitions
- the objective of! system is that the driver can not perform most of the activities that generate lack of attention while driving, since it is required that both hands are holding the steering wheel simultaneously while driving.
- shock absorbers better brakes, etc.
- REPLACEMENT SHEET (RULE 26) warning beep when we have not fastened the seat belt.
- the beep is so annoying that the occupants prefer to tie their seat belts to drive listening.
- REPLACEMENT SHEET (RULE 26) Some of these devices are currently in testing processes.
- One of the first systems developed consisted of a helmet with multiple electrodes, capable of controlling brain activity and detecting driver fatigue or sleep.
- the system worked reasonably, but it was so cumbersome, that it was not a device that could be used regularly, every time someone got behind the wheel of a vehicle.
- the Jaguar / Land Rover company has developed a system capable of detecting brain activity through specialized sensors located on the steering wheel. With these sensors, and through the hands, they are able to detect tiredness and sleep in the driver. As it has been published, it seems that the system is about to be applied in series vehicles.
- Hoffman and Krippner have developed a fatigue detection system based on hand pressure on the steering wheel. They have designed a system of pressure detectors, which, connected to a switchboard and following certain custom patterns, are able to detect fatigue and / or sleep in the driver. Some other initiatives have tried to control the position and movements of the driver's eyes to, again, using certain custom patterns, detect fatigue and / or sleep in the driver. They have even developed portable systems with this technology. Other initiatives have been directed, through artificial vision, patterns
- REPLACEMENT SHEET (RULE 26) Let us then explain the "System of detection of” risk activities while driving "based on the control of the position of both hands holding e! steering wheel".
- the system consists of a series of capacitive sensors, without exciting others of any other type, located around the steering wheel and on the back side of the steering wheel, intended to verify that both hands are located around the steering wheel, which will guarantee that we detect the fingers of the driver grabbing the steering wheel, around it.
- the gear lever or the center console control can also be equipped with these sensors. This can help to ignore part of the steering wheel signals in the event that the driver needs to change speed, in vehicles with manual transmission, or type of driving, in vehicles with automatic transmission. We will do the same with the button on the center console, for example, to be able to operate the “Hands-free” device or other devices.
- the fault indicators will be activated simultaneously to the beep inside the vehicle, which will inform the other users of the road, so that they can be prevented from improper maneuvering and / or
- Window Parameters As indicated, the detection system will have a series of “Window Parameters”, which will allow to inhibit the alarm signals in certain circumstances. These are some of the “Parameters window” with which the system will have:
- the system will start operating from a certain speed, for example, 15 km / h. It could also be active all e! time while the car is in circulation.
- the system will allow a time of inhibition of the same in the event that the driver is doing some work of adjusting auxiliary elements to driving, for example, 3 seconds.
- the system will control the rotation position of the steering wheel, so that a turn greater than certain degrees will also inhibit the system for a certain time. It is that in moments of driving in more or less complicated situations, the system does not generate distractions to the driver. For example, we will set an operating sector within 15 or more of the steering wheel position in its centered position, in this case, we will inhibit the system for, for example, 10 seconds.
- detectors in said console will also be enabled, allowing the handling of these controls for a maximum of time. For example, 5 seconds.
- a soft sound warning will be activated every certain time, for example, every 45 seconds, activating the "Dead Man” control. This system will work similarly to how it works on trains. This control
- REPLACEMENT SHEET (RULE 26) it will require that the hands be released and repositioned on the steering wheel in a certain sequence and in a certain order. Open the left hand slightly, place the left hand around the steering wheel, open the right hand slightly, place the right hand around the steering wheel, within a certain period of time, for example 300 ms. In this way the Dead Man will be deactivated again for another period of time.
- the system may consider, in addition to the previous ones, a period of waiting for the activation of notices, for example, 2 seconds, for the realization of some activity not included among those contemplated in this text.
- Window parameters will be configurable from the manufacturer's own software! vehicle and / or device, in this way, to be able to adapt to the new needs that may arise, and be able to adapt to different legislations of the different places and to the possible changes that in any of these legislations could have over time .
- REPLACEMENT SHEET (RULE 26) high-risk. If you are thirsty, you must stop the vehicle in a safe area and then drink.
- the device may be used in combination with any other device to aid in the detection of fatigue or lack of attention had or had. It is that with this device, driving is safer, and the sum of any other system or technology, could bring an increase to such safety.
- REPLACEMENT SHEET (RULE 26) We will have at least two units as described above, one located on the steering wheel itself and which will be connected to the spiral of the CAN Bus on the steering wheel and the second will be installed on the vehicle dashboard to detect both the location of the hands on the lever of changes as on the central command of the vehicle console.
- the control unit will be in charge of processing the signals received from the two units described above and acting on the warning signals described in previous chapters.
- the application of the system and the integration with CAN Bus will be done by connecting the output of the MCP 2551 chip or similar and transmitting the messages with a specific identifier to CAN Bus.
- the two auxiliary switchboards by means of specific shipping identifiers, will induce data to CAN Bus, which will be received in the control unit, dedicated or not, of the hand detection system on the steering wheel.
- data such as vehicle speed, steering wheel rotation and any other, capable of providing necessary data for the system, will also be processed by it. From there, said switchboard will activate the necessary signals to alert both the driver and other users of the route of the risk situation detected in the vehicle.
- the system can be incorporated into new models, with specific designs, as well as existing ones by means of portable devices with simple installation on portable elements, including electrodes, duly protected and attached to the back of the steering wheel.
- the detectors in this case capacitive, will be located on the back of the steering wheel, on the gearshift, adapting to the shape that it could have and on the center steering wheel of the console on vehicles that have this device.
- Fig. 1 Schematic image of the steering wheel on the back, in which the possible location of capacitive or other sensing electrodes, which will be located after a protection of plastic, leather or other material, are displayed in shading. can be hidden from view of the user. You can also appreciate the location
