Patent number: 11548530Abstract: 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. When the activation condition is satisfied, the vehicle travel control device generates a second target trajectory that is the target trajectory for the travel assist control. When the second target trajectory is generated during the automated driving, or when the second target trajectory is generated during the automated driving and a priority condition for giving priority to the second target trajectory is satisfied, the vehicle travel control device executes the vehicle travel control by giving more weight to the second target trajectory than to the first target trajectory.Type: GrantFiled: September 15, 2020Date of Patent: January 10, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takayuki Goto, Yoshinori Watanabe, Nobuhide Kamata, Kazuyuki Fujita, Masahiro Harada
