Abstract

A method and system for controlling a vehicle includes receiving vehicle position information from a positioning system and combining the position information with information from a map database and a driver behavior model to control the vehicle'"'"'s speed and braking for not only the current roadway the vehicle is operating on but also on upcoming road sections.

Claims

1. A method for controlling a vehicle comprising:

receiving an approximate vehicle position from a positioning system;

retrieving a plurality of map information comprising at least road attributes, from a map database, said plurality of map information being related to said approximate vehicle position;

retrieving a plurality of driver behavior information from a driver behavior database, said plurality of driver behavior information being related to said plurality of map information;

generating a driver behavior model by relating said plurality of road attributes to said plurality of driver behavior information by using a neural network device;

generating a speed plan based on said plurality of map information and said driver behavior model;

outputting said speed plan to a vehicle control module comprising an engine control device and a brake system control device; and

using said engine control device and said brake system control device to control the speed of the vehicle autonomously on said speed plan.

2. The method of claim 1, further comprising a step of inputting to said driver behavior database a driver identification signal, wherein said retrieved plurality of driver behavior information is related to said driver identification signal.

3. The method of claim 1, wherein said vehicle control module comprises a driver display unit, wherein said driver display unit presents to a driver of said vehicle at least one instruction related to said speed plan.

4. A system for controlling a vehicle comprising:

a positioning device, said positioning device being capable of determining an approximate position of said vehicle;

a map database, said map database being capable of determining a plurality of map information, said plurality of map information being related to said approximate position of said vehicle;

a driver behavior database, said driver behavior database being capable of determining a plurality of driver behavior information, said plurality of driver behavior information being related to said plurality of map information;

a driver behavior model determined by a neural network device which relates said plurality of map information with said plurality of driver behavior information;

a computing device, said computing device being capable of generating a speed plan based on said plurality of map information and said driver behavior model; and

a vehicle control module, comprising a speed control device and a brake system control device, for controlling said vehicle autonomously based on said speed plan.

5. The system of claim 4, wherein said vehicle control module comprises a driver display unit.
