A primary objective of the present invention is to provide a composite autonomous driving assistant system for making decision and a method of using the same, which efficiently makes a longitudinal-controlling autonomous driving assistant device and a lateral-controlling autonomous driving assistant device coexist and defines a threshold condition for two different autonomous driving assistant devices, and which determines that the longitudinal-controlling autonomous driving assistant device or the lateral-controlling autonomous driving assistant device has to shut at present according to states of a vehicle and an environment, thereby improving autonomous driving safety.
Another objective of the present invention is to provide a composite autonomous driving assistant system for making decision and a method of using the same, which shuts or starts autonomous assistant driving according to the driver’s will, so as to control dominance of driving a vehicle, thereby improving driving safety.
To achieve the abovementioned objectives, the present invention provides a composite autonomous driving assistant system for making decision arranged on a vehicle to automatically assist in driving the vehicle, and the composite autonomous driving assistant system for making decision comprises: a longitudinal-controlling autonomous driving assistant device controlling a moving speed of the vehicle; a lateral-controlling autonomous driving assistant device controlling a rotating angle of the vehicle; a sensing device sensing states of the vehicle and an environment and generating at least one sensing signal comprising a speed signal, a distance signal, a rotation angle signal and a deceleration signal; and a controller electrically connected with the longitudinal-controlling autonomous driving assistant device, the lateral-controlling autonomous driving assistant device and the sensing device, receiving the sensing signal and figuring out a collision period according to the speed signal and the distance signal. When the controller determines that the collision period is less than a preset collision period and that the deceleration signal is larger than a preset deceleration, the controller generates a turn-stopping signal and transmits the turn-stopping signal to the lateral-controlling autonomous driving assistant device to stop controlling the rotating angle of the vehicle. When the controller determines that the rotation angle signal is larger than a preset angle, the controller generates a speed-stopping signal whereby the longitudinal-controlling autonomous driving assistant device stops controlling the moving speed of the vehicle.
