Autonomous driver assistance system and autonomous driving method thereof
First Claim
1. An autonomous driving method performed by an autonomous driver assistance system mounted in a vehicle, the method comprising steps of:
- generating a planned route to a destination;
performing road detection of the planned route to obtain roadway information in front of the vehicle including an image of lane markings, a distance to a vehicle ahead, a signal of direction indicators of the vehicle ahead, and a collision alert;
performing positioning detection to obtain an actual position of the vehicle compared with the planned route to determine if a driving route of the vehicle matches the planned route;
integrating driving safety of the vehicle to detect and determine a driving condition of a driver of the vehicle and actively control a travelling condition of the vehicle upon autonomous driving; and
performing the autonomous driving to determine if the image of the lane markings has lane markings, if the lane markings are available, controlling the vehicle to drive along the lane markings to the destination by the autonomous driving according to the steps of generating the planned route and performing road detection of the planned route, if the lane markings are not available, detecting if the vehicle ahead is driving along the same planned route, and if determining that the vehicle ahead follows the same planned route, combining the autonomous driving and the positioning detection to drive the vehicle and follow the vehicle ahead to the destination.

Abstract
An autonomous driver assistance system is integrated with a vehicular control system to constantly detect ambient road environment of the vehicle, identify a vehicle ahead with same driving route to a destination, and follow the vehicle ahead by autonomous driving to the destination. Signals of direction indicators of the vehicle ahead can be recognized to determine a driving direction and driving state of the vehicle ahead beforehand, thereby reducing the chances of emergency brake and collision and increasing driving efficiency. Without expensive radar detection equipment, the present invention can be easily integrated with a vehicular control system to tackle the high installation cost and integration difficulty of conventional autonomous driver assistance apparatuses.

7. An autonomous driver assistance system mounted on a vehicle and comprising:
-
an autonomous driving control device adapted to connect to a vehicle control system of the vehicle for issuing an alert or controlling a travelling condition of the vehicle; a road detection device connected to the autonomous driving control device for acquiring a roadway image in front of the vehicle and detecting a distance to a vehicle ahead and a signal of direction indicators of the vehicle ahead; a telemetic device connected to the autonomous driving control device for transmitting radio signals out or receiving external radio signals, planning a driving route of the vehicle and positioning the vehicle; and a vehicle safety integration device connected to the autonomous driving control device for detecting a driving condition of a driver of the vehicle; wherein the road detection device determines if the roadway image has lane markings, if the lane markings are available, the telemetic device controls the vehicle to drive along the lane markings to the destination by autonomous driving according to the planned driving route and the positioning of the vehicle, if the lane markings are not available, the telemetic device detects if the vehicle ahead is driving along the same planned route, and if determining that the vehicle ahead follows the same planned route, the telemetic device combines the autonomous driving and the positioning to drive the vehicle and follow the vehicle ahead to the destination. - View Dependent Claims (8, 9)
