Patent number: 9821802Abstract: 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 turn angle signal of the sensing signal is larger than a preset angle, the controller generates a speed-stopping signal. The system establishes a switching threshold condition when the plurality autonomous driving assistant devices coexist.Type: GrantFiled: April 29, 2016Date of Patent: November 21, 2017Assignee: Automotive Research & Test CenterInventors: Po-Kai Tseng, Shun-Hung Chen
