Abstract
In accordance with the present invention, a position of a vehicle is detected by a receiver at the vehicle from a global positioning system. A speed limit associated with the position is determined from a centralized database accessible via a wireless network. An actual speed of the vehicle at the detected position is compared with the determined speed limit for the detected position, such that if it is determined that the actual speed exceeds the determined speed limit at the detected position, the driver may be alerted.
Description
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates in general to a vehicle speed detection system and, in particular, to a method, system and program for auditing driver compliance to a current speed limit range. Still more particularly, the present invention relates to a method, system and program for determining whether the vehicle's actual speed is within a current position-dependent speed limit range without the use of local speed transmitters.
2. Description of the Related Art
Speed limits and driving conditions along any given route may change frequently, particularly in urban settings. In addition, along a given route speed limits may change according to the time of day, such as during school hours or rush hours.
The current and accepted method of informing the driver of the speed limit is through posted speed limit signs on the side of the road. However, it is easy for drivers to become distracted and not notice changes in speed limit sign postings. In addition, drivers may intentionally or unintentionally exceed the posted speed limit. Exceeding a posted speed limit can have negative consequences such as personal injury, property damage, and fines from speeding tickets. Moreover, when multiple speed limit signs are posted for a single section of road (e.g. a day speed limit and a night speed limit), a driver must determine which speed is applicable.
In order to aid drivers with information about changing speed limits, several systems in addition to posted speed limit signs have been developed. For example, U.S. Pat. No. 6,008,740 ('740) describes a system for placing local transmitters near roadsides that are set to broadcast the speed limit for that range of road within a particular range and frequency. According to '740, vehicles equipped with receivers tuned to the broadcast frequency can detect speed limit broadcasts when within the broadcast range in order to provide an on-board alert to drivers exceeding the broadcast speed limit.
However, while '740 does provide an alternate system to posting speed limit signs, '740 requires placing a locally broadcasting transmitter for each speed limit designation along a roadway and in each vehicle utilizing the system. The cost of implementing such a system of multiple local transmitters is undesirable in that it would be costly to place as many local transmitters as would be needed for the system to be effective.
For example, consider an urban area with a dense network of roads, each with unique speed limits. A speed limit system would have to correctly identify current street locations and speed limits, and not be confused with an adjacent street with a potentially different speed limit. This differentiation would be difficult for a system using radio transmission. Inconsistencies in broadcast range would most likely require a tight web of low power transmitters. Purchase and maintenance costs for this type of system with a large number of units would typically be prohibitive.
Therefore, in view of the foregoing, it would be desirable to provide a method, system and program for alerting a driver of current speed limits which does not require an excessive number of transmitters and which would not present transmission difficulties in areas with multiple speed limits in a small range. In particular, it would be advantageous to provide such a centralized database of position-dependent speed limits wherein designations according to type of car, time of day, weather conditions, etc. are included.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a vehicle speed detection system.
It is another object of the present invention to provide a method, system, and program for auditing driver compliance to current speed limits.
It is yet another object of the present invention to provide a method, system and program for determining whether the vehicle's actual speed is within a current position-dependent speed limit range without the use of local speed transmitters.
In accordance with the present invention, a position of a vehicle is detected by a receiver at the vehicle from a global positioning system. A speed limit associated with the position is determined from a centralized database accessible via a wireless network. An actual speed of the vehicle at the detected position is compared with the determined speed limit for the detected position, such that if it is determined that the actual speed exceeds the determined speed limit at the detected position, the driver may be alerted.
All objects, features, and advantages of the present invention will become apparent in the following detailed written description.

Referring now to
FIG. 2
, there is illustrated a pictorial illustration of a vehicle speed auditing system in accordance with the method, system, and program of the present invention. As illustrated, computer system
10
is incorporated within vehicle
50
. In particular, there is a hardware interface between computer system
10
and components of vehicle
50
, such as the car's speedometer and cruise control device.
Computer system
10
includes a speed comparison software application
40
and speed controller software application
42
that execute within computer system
10
. Speed comparison application
40
preferably determines whether or not vehicle

is exceeding the current speed limit and alerts the driver of speed violations and other road conditions that may be useful to the driver. Speed controller application
42
preferably determines a signal for automatically adjusting the speed of vehicle
50
if in excess of the current speed limit.
A GPS position of vehicle
50
is preferably passively detected by GPS receiver
44
. In particular, GPS receiver
44
may passively detect a position according to the GPS subscription or service utilized. For example, GPS receiver
44
may passively detect a position by detecting satellite transmissions and/or a base broadcasting location.
Speed comparison application
40
utilizes a GPS position, speed limit for the current GPS position, and actual speed of vehicle
50
to determine whether or not vehicle

In the example depicted in Table 1, GPS position ranges Area 1, Area 2, Area 3 and Area 4 are included. In particular, each of these areas preferably includes a range of multiple GPS locations indicated in a standard GPS protocol including latitude, longitude, and elevation.
In the example of Area 1, maximum speed limits (MX) are provided for cars and trucks dependent upon whether it is day time or night time. In addition, a road condition warning that the flow of traffic is currently reduced to 50 MPH at GPS Position 1 is provided, such that a driver may prepare to slow down according to the speed of traffic. In particular, some roadways may include sensors that determine the average speed of the flow of traffic and report that speed to vehicular speed limit database
46
.
In the example of Area 2, a posted speed limit of 75 MPH is designated for any vehicle at any time. A road condition warning about the flow of traffic is provided.
In the example of Area 3, a minimum (MN) and maximum speed limit are designated for a left lane of the highway. In addition, a conditional maximum speed limit is designated if the temperature is at freezing temperatures or below, which would negate the minimum speed. Moreover, a road condition warning of a wreck at Position 2 of Area 3 is provided such that a driver is alerted to possible slowdowns in traffic.
In the example of Area 4, maximum speed limits are designated according to time of day. For example, between 2-4 the maximum speed limit is 20 MPH while all other times the maximum is 40 MPH.
According to a preferred embodiment of the present invention, computer system
10
may transmit the current GPS position of vehicle
50
as detected by GPS receiver
44
and the vehicle type to server
47
. Server
47
would then search vehicular speed limit database
46
to determine the speed limit associated with the GPS position, vehicle type, and time of day. In an alternate embodiment, computer system
10
accesses vehicular speed limit database
46
, or portions thereof, and searches vehicular speed limit database
46
according to the detected GPS position of vehicle
50
. In particular, it may be advantageous to transmit portions of vehicular speed limit database
46
for expected GPS position ranges to computer system
10
such that computer system
10
does not need to remain constantly connected to wireless network
48
in order to determine current speed limits.
In particular, speed comparison application
40
is preferably enabled to determine a speed and direction of travel of vehicle
50
from multiple detected GPS positions. The velocity of travel may also be determined utilizing standard speed detection instrumentation coupled to vehicle
50
. By detecting a speed and direction of travel of vehicle
50
and searching vehicular speed limit database
46
utilizing the speed and direction of travel, server
47
is preferably enabled to also transmit upcoming speed limits and road conditions for GPS position areas anticipated by the direction of travel and offer alternative routes where applicable.
In addition, where there are varying speed limits and road conditions for a particular section of road-way, by determining which direction vehicle
50
is traveling, the speed limit and road condition for that particular section of road-way in the direction traveled can be determined from searching speed limit database
46
. Moreover, if there are road conditions that may become more dangerous with increased or decreased speed according to the make of the car, then by searching speed limit database
46
according to the direction and speed of travel, the effects of road conditions may be specified according to the speed of vehicle
50
, direction of travel, and the make of vehicle
50
. For example, a car that is heavier and has snow tires may be able to travel at a faster speed uphill in snow conditions than a smaller, lighter car without the aid of specialized tires.
Speed limit database
46
preferably includes road condition details, as depicted in Table 1. Road condition details may be accumulated via multiple methods including, but not limited to, multiple types of sensors positioned at roadsides, information called in by drivers, satellite monitoring, and other such methods. For example, satellites may monitor the traffic flow of roads. Weather sensors positioned near roads may detect the light levels, fog levels, temperature levels, precipitation levels, wind levels, etc.
In response to determining that a vehicle is not within a posted speed limit range and/or receiving road condition signals, speed comparison application
40
preferably outputs indicators to a driver according to driver output preferences. A driver may designate preferences for outputs including, but not limited to, audio outputs, text outputs, visual outputs, etc. In particular, a driver's output preferences may be stored on computer system
10
according to an identifier for the driver and therefore subsequently retrieved. Identifiers for output preferences may include, but are not limited to, vocal identifiers, alphanumeric identifiers, and biometric identifiers.
Speed controller application
42
preferably provides for adjusting a speed governor for vehicle
50
according to current speed limits. In particular, a driver may include a preference for speed controller application
42
to automatically govern the speed of vehicle
50
or prompt the driver to select speed governing when excessive speeds are detected. In addition, a driver may request speed governing within a particular range of the speed limit. For example, a driver may request that on highways speed controller application
42
govern speeds to no more than five miles below the posted speed limit.

84
illustrates adjusting the actual speed to within the designated speed limits, minimum or maximum; and the process passes to block
