Abstract
Disclosed are systems and methods for driver performance assessment and improvement. The systems and methods may be: active for warning purposes only; passive for monitoring purposes only; and active and passive. Any of the foregoing system and methods may be cooperative as well.
Claims20
A driver performance assessment and improvement method comprising:
- inputting, via an on-board global positioning satellite (GPS) tracking computer, information on vehicle configuration and load parameters;
- automatically, via the on-board GPS tracking computer, locating the vehicle and determining its direction of travel and speed once driving is underway;
- automatically, via the on-board GPS tracking computer, selecting a road segment that the vehicle is traversing from a linked map data base that contains accurate three dimensional characterizations of road centerlines, curve radii and slopes, and pre-calculated recommended safe speeds for various vehicle types, loads and trailer configurations;
- automatically, via the on-board GPS tracking computer, predicting the path of the vehicle;
- automatically, via the on-board GPS tracking computer:
- selecting the recommended safe speed (RSS) from the database;
- and
- calculating the RSS that the vehicle can use to transit a next road segment from the information on vehicle configuration and load parameters along with the curve radii and slopes;
- automatically, via the on-board GPS tracking computer, recording actions of a driver as well as actual speed and accelerations as the vehicle traverses a particular road segment;
- automatically, via the on-board GPS tracking computer, transmitting the recorded driver behavior and other information to a server for storage and analysis;
- and
- automatically, via the server, analyzing the recorded driver behavior and other information to score driver performance.

- automatically, via the on-board GPS tracking computer, calculating a look-ahead distance sufficient for the vehicle to be slowed to a safe speed for upcoming road segments;
- and
- automatically, via the on-board GPS tracking computer, providing a safe speed and warnings to the driver and a point at which the vehicle must begin braking for upcoming road segments.
