Abstract

A combination radar/laser detector with environmental sensors is programmed to provide a range of functions, including weather information, road conditions and the like, and in some cases to incorporate road-specific information in functionality. The road-specific information may be provided by roadside RF broadcast terminals. In a preferred embodiment the system monitors characteristics that indicate a driver'"'"'s state of awareness, and audio alerts are provides when the system determines a driver is dozing or drifting toward a dozing state. In various embodiments a broad range of functionality is provided based on received and sensed parameters.

Claims

1. An enhanced Radar/Lidar detector for a vehicle, comprising:

a detector for sensing one or both of radar or laser signals directed on the vehicle to track vehicle speed;

an input from one or more sensors mounted on or in the vehicle for sensing one or more physical characteristics in the immediate vicinity of the vehicle;

a microcontroller for managing system functions;

an electronic memory for storing data, algorithms, and operating routines; and

a display for reporting to a user;

wherein the system monitors for the radar or laser signals, alerts the user if and when such signals are detected, and displays results of the sensor input in real time to the user.

2. The system of claim 1 wherein the one or more physical sensors include sensors for one or more of inside temperature, outside temperature, acceleration/deceleration, wind velocity, wind direction, air pressure, humidity, or the Earth'"'"'s magnetic field.

3. The system of claim 2 wherein one of the physical sensors is a magnetometer for sensing the Earth'"'"'s magnetic field, and the system additionally comprises circuitry and software enabling the microprocessor to display vehicle compass direction derived from readings from the magnetometer.

4. The system of claim 2 wherein the user is a driver of the vehicle, and further comprising an audio system and doze-alert software executed in the background at times the vehicle is in motion, the system, via the doze-alert software, gathering sensor data and processing same, and comparing with stored data to make a determination as to the driver'"'"'s state of awareness, and, in the event of determining the driver may doze or is dozing, sounding an audible warning alert to the driver.

5. The system of claim 4 wherein the doze-alert software operates on an escalating scheme, wherein separate determinations are made based on sensor inputs as to a level of danger, and separate alerts are made, each one more urgent than the last as determined danger increases.

6. The system of claim 1 further comprising an interactive user interface enabling the user to at least select alternative functions for the system.

7. The system of claim 1 further comprising an RF receiver enabled to receive and decode data transmitted from extra-vehicular sources.

8. The system of claim 7 further comprising one or more roadside RF transmitters transmitting data and messages to the RF receiver in the vehicle.

9. The system of claim 8 wherein messages transmitted by roadside transmitters include data on road characteristics to be soon encountered by the vehicle.

10. The system of claim 9 wherein the road characteristics include one or more of curve characteristics for the roadway and incline characteristics for the roadway.

11. An enhanced laser detector for a vehicle, comprising:

a detector for identifying laser signals directed on the vehicle to track vehicle speed;

an input from one or more physical sensors mounted on or in the vehicle for sensing one or more physical characteristics in the immediate vicinity of the vehicle;

a microcontroller for managing system functions;

an electronic memory for storing data, algorithms, and operating routines; and

a display for reporting to a user;

wherein the system monitors for the laser signals, alerts the user if such signals are detected, and displays results of the sensor input in real time to the user.

12. The system of claim 11 wherein the one or more physical sensors include sensors for one or more of inside temperature, outside temperature, acceleration/deceleration, wind velocity, wind direction, air pressure, humidity, or the Earth'"'"'s magnetic field.

14. The system of claim 12, wherein the user is a driver of the vehicle, and further comprising an audio system and doze-alert software executed in the background at times the vehicle is in motion, the system, via the doze-alert software, gathering sensor data and processing same, and comparing with stored data to make a determination as to the driver'"'"'s state of awareness, and, in the event of determining the driver may doze or is dozing, sounding an audible warning alert to the driver.

15. The system of claim 14 wherein the doze-alert software operates on an escalating scheme, wherein separate determinations are made based on sensor inputs as to a level of danger, and separate alerts are made, each one more urgent than the last as determined danger increases.

16. The system of claim 11 further comprising an interactive user interface enabling the user to at least select alternative functions for the system.

17. The system of claim 11 further comprising an RE receiver enabled to receive and decode data transmitted from extra-vehicular sources.
