1. Field of the Invention
The present invention represents a significant step forward in the field of vehicle safety. Vehicular safety is a function of the vehicle speed, road conditions, driver experience, driver exerting control, driver alertness, driver distractions and elapsed driving time. The speedometer is the traditional safety indicator for the driver. The steering wheel has been proposed in known technology for use to detect the sobriety or sleepiness of the driver. Known steering wheel systems ignore current opportunities to improve operation by limiting themselves to detecting only a single unsafe driving practice like driving while drowsy. Thus missing additional driver caused unsafe conditions and ignoring the fact that multiple drivers with differing driving habits may drive a single vehicle and that more parties than the driver may be made safer by receiving a indication of the unsafe driving practice. The instant invention contains a unique combination of features that addresses present and future driver caused hazards by utilizing state of the art wireless, sensing and recording technology, programmability and introduces ways of preventing the unsafe condition from occurring in the first place.

None of the above Patents or Published Patent Applications singly or in combination is seen to describe the present invention as claimed.
The present invention is a driver safety system for vehicles. Generally, the instant invention solves the problem of texting and other driver distractions, driver control, driver alertness, driver fatigue as a function of driver experience, vehicle speed and road conditions. In addition to solving these problems added features that alert parents, drivers of nearby vehicles and authorities as well as alleviating driver discomfort and fatigue are also provided.
The preferred embodiment of the present invention provides additional unique features by use of GPS for determining vehicle speed, controlling the drivers hand positions depending on vehicle speed, driver experience and road conditions, providing gloves to facilitate sensing hand position when contact conductive sensors are used on the steering wheel and other features that will become apparent in the body of the specification and claims of this patent application.
The primary objective of the present invention is to provide the driver with an indication that safe driving principles are being broken.
An objective of the present invention is to sense the position of two hands on the steering wheel as a measure of practicing safe driving practices.
A further objective of the present invention is to detect and indicate driver inattentiveness or fatigue,
A further objective of the present invention is to allow brief periods of single hand on the steering wheel for changing of hand position the time period being a function of driver experience, vehicle speed and road conditions.
A further objective of the present invention is to change the positions for the two hands to what are considered safe practices as the vehicle speed and driving conditions change.
A further objective of the present invention is to receive speed and road condition information over wireless sources including GPS and automatically react to changes in speed or driving conditions.
A further objective of the present invention is to identify the driver and set the criteria for safe driving practices based on driver experience level.
A further objective of the present invention is to escalate the indication that unsafe driving practices are in practice by flashing external lights or the horn to warn nearby drivers and attract the attention of authorities.
A further objective of the present invention is to further discourage the practice of unsafe driving principles by recording occurrences for parental, owner or rental agency review.
Still a further objective of the present invention is to change what are considered safe practices depending on the experience of the driver and the elapsed driving time since the driver has had a break.
A further objective of the present invention is to alert the driver of the positions to hold the steering wheel that are considered safe at the current driving speed and road conditions.
Still a further objective of the present invention is to alleviate driver fatigue or discomfort by physical changes in the steering wheel.
A final objective of the current invention is to provide a system meeting all of the aforementioned objectives in an aftermarket, steering wheel cover.
a: is a table of hand positions considered safe as a function of controller inputs.
b: is a table of controller outputs as a function of drivers being absent from the steering wheel segments considered safe.
a is a table showing a preferred set of criteria the system controller 20 uses to determine which steering wheel indicators 1 and steering wheel sensors 2 to activate. The table is broken into two major sections marked Novice Driver and Expert driver. With both expert and novice drivers all of the sensors 1 and indicators 2 are activated when the vehicle is moving at below a pre-determined low speed. However, the range of hand positions that is activated is reduced at a higher pre-determined speed and reduced further depending on good road or poor road conditions. The same is true of the expert driver except that the expert driver is given more leeway to rest one hand in sectors 14 or 15 on a good road or during a long drive.
b is a table of the system controller 20 responses to unsafe driving practices indicated by exceptions to keeping the drivers hands in the indicated steering wheel sectors 11-18. The first line of the table shows that is only one hand is sensed for a short time that the driver will be reminded by an in car alarm. If only one hand is sensed by the activated steering wheel sensor 2 an external alarm which could include flashing the headlights or blowing the horn externally to warn nearby drivers or authorities of unsafe driving practices. A recorder 7 may also be included so that a drivers parent or mentor is aware that unsafe practices are resulting in external alarms and placing the driver and passengers in danger. The absence of any hands on the steering wheel 1 while the vehicle is moving results in immediate activation of the internal alarm 8, external alarm 9 and recorder 7.
The second embodiment of the present invention of
