Patent number: 11724715Abstract: A vehicle control system generates a first target trajectory, which is a target trajectory for an automated driving of a vehicle, and executes vehicle travel control based on the first target trajectory. The vehicle control system generates a second target trajectory which is a target trajectory which does not conflict with a restrict condition, when the travel based on the first target trajectory conflicts with a safety restrict condition, and executes travel assist control by using the second target trajectory. The vehicle control system judges whether or not a resurgence condition is satisfied by using the first target trajectory that is generated during the execution of the travel assist control. If it is judged that the resurgence condition is satisfied, the vehicle control system returns to the execution of the vehicle travel control from that of the travel assist control.Type: GrantFiled: October 13, 2020Date of Patent: August 15, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yoshinori Watanabe, Kazuyuki Fujita, Takayuki Goto, Masahiro Harada, Nobuhide Kamata

Publication number: 20230148202Abstract: A vehicle travel control device executes vehicle travel control such that a vehicle follows a target trajectory. An automated driving control device generates a first target trajectory that is the target trajectory for automated driving of the vehicle. The vehicle travel control device further determines whether or not an activation condition of travel assist control is satisfied.
