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.
Claims5
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.

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.
