Patent number: 11628835Abstract: A vehicle control system includes a first unit configured to generate a target trajectory based on a travel plan of the vehicle, and a second unit configured to execute vehicle travel control such that the vehicle follows the target trajectory. During the automated driving, the first unit transmits automated driving information to the second unit. The system includes a memory device in which driving environment information is stored, and a processor for controlling a travel control amount. During the automated driving, the processor executes preventive safety control for intervening in the travel control amount so as to prevent or avoid a collision between the vehicle and an obstacle based on the driving environment information. In the preventive safety control, the processor changes an intervention degree to the travel control amount based on the automated driving information.Type: GrantFiled: October 13, 2020Date of Patent: April 18, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kazuyuki Fujita, Yoshinori Watanabe, Takayuki Goto, Masahiro Harada, Nobuhide Kamata

Patent number: 11618473Abstract: 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. Even 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 first target trajectory is satisfied, the vehicle travel control device executes the vehicle travel control by giving more weight to the first target trajectory than to the second target trajectory.Type: GrantFiled: September 14, 2020Date of Patent: April 4, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takayuki Goto, Yoshinori Watanabe, Nobuhide Kamata, Kazuyuki Fujita, Masahiro Harada
