Robotic driving system

摘要

A system that enables a vehicle to follow a traffic rule when traveling in a road network includes a database that stores data relating to at least one feature of the road network, a location detector that detects a location of the vehicle relative to the road network, a sensor that senses at least one object in a vicinity of the vehicle, and a processing system that controls the vehicle to autonomously obey at least one traffic rule, or provides a notification to a driver of the vehicle to enable the driver to obey at least one traffic rule, based on the detected location of the vehicle, data retrieved from the database relating to at least one feature of the road network, and data relating to at least one object sensed by the sensor.

1. A system that enables a vehicle to follow a traffic rule while traveling in a road network, comprising:
a database that stores data relating to at least one feature of the road network; a location detector that detects a location of the vehicle relative to the road network; a plurality of sensors, including at least one sensor that senses at least one object in a vicinity of the vehicle; and a processing system that controls the vehicle to autonomously obey at least one traffic rule, or provides a notification to a driver of the vehicle to enable the driver to obey at least one traffic rule, based on the detected location of the vehicle, data retrieved from the database relating to at least one feature of the road network, and data relating to at least one object sensed by the sensors, wherein the object sensed is an obstruction, the processing system includes a memory which stores a plurality of lookup tables, each of the lookup tables receive different data from a corresponding and different one of the plurality of sensors representing a corresponding condition local to the vehicle, where at least one corresponding condition represents data of the obstruction, and outputs a maximum safe speed, for each lookup table, based on the received data from each of the different sensors, the plurality of lookup tables comprises at least one of a vehicle congestion speed lookup table, a weather condition lookup table, and a road condition lookup table; and the processing system selects the minimum of all of the maximum safe speeds outputted by the lookup tables, and controls the vehicle speed not to exceed the selected minimum speed and to avoid the obstruction based upon data from the lookup tables and the sensed distance of the vehicle from the obstruction.
