Composite autonomous driving assistant system for making decision and method of using the same

Abstract

A composite autonomous driving assistant system for making decision and a method of using the same is provided. A longitudinal-controlling autonomous driving assistant device and a lateral-controlling autonomous driving assistant device start to automatically assist in driving a vehicle. Then, a sensing device senses states of the vehicle and an environment and generates one sensing signal. When a controller determines that the collision period is less than a preset collision period and that a deceleration signal of the sensing signal is larger than a preset deceleration, the controller generates a turn-stopping signal. When the controller determines that a rotation angle signal of the sensing signal is larger than a preset angle, the controller generates a speed-stopping signal. The present invention establishes an excellent switching threshold condition when the plurality autonomous driving assistant device coexist.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates to an autonomous driving assistant technology, particularly to a composite autonomous driving assistant system for making decision and a method of using the same. The system switches autonomous assistant driving required according to an environment.Description of the Related Art[0002]An autonomous driving assistant system can use distance or image sensing devices to sense an external environment of a vehicle body so that a processor generates a control vehicle body signal according to the external environment, so as to control the state that the vehicle body moves on. As a result, the autonomous driving assistant system can assist in driving the vehicle, thereby improving driving and road safety and reducing workload for long-term driving.[0003]In the United States, the National Highway Traffic Safety Administration (NHTSA) of Department of Transportation (DOT) has proposed a formal classification s...

AI Technical Summary

Benefits of technology

This patent describes a system and method for making decisions for an autonomous driving vehicle. The system can decide to control the vehicle in two directions, either longitudinally or laterally. The decision is based on the vehicle's circumstances and the surrounding environment. The system can also determine which direction to control the vehicle based on the driver's intentions, improving safety and allowing for better control of the vehicle. Overall, the system aims to make autonomous driving safer and more efficient.

Problems solved by technology

However, when only one autonomous assistant system is installed on the vehicle, the autonomous assistant system is shut as long as a steering wheel, a throttle or a brake is driven.

When a longitudinal-controlling autonomous assistant system and a lateral-controlling autonomous assistant system are installed on a vehicle, the vehicle is in the following dangerous situation without using conversion mechanism between the longitudinal-controlling autonomous assistant system and the lateral-controlling autonomous assistant system.

When the vehicle corners too much, the longitudinal-controlling autonomous assistant system and the lateral-controlling autonomous assistant system simultaneously start whereby the vehicle turns over and deviates from the lane to cause greater damage.
