  • Publication number: 20210146956
    Abstract: A vehicle traveling control system according to the example in the present disclosure communicates with an automatic operation control system which drafts a traveling plan of the vehicle, and performs an automatic traveling control for automatically running the vehicle along the traveling plan received from the automatic operation control system. The vehicle traveling control system predicts a risk based on information about surrounding environment of the vehicle, and performs, when the risk is predicted, a risk avoidance control to intervene in the automatic traveling control in order to avoid the risk. When the risk avoidance control is executed, the vehicle traveling control system transmits information on the risk avoidance control to the automatic operation control system.

  • Publication number: 20210107517
    Abstract: 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.

  • Publication number: 20210107522
    Abstract: 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.

  • Publication number: 20210107516
    Abstract: A vehicle control system generates at least one primary candidate of a target trajectory for an automated driving of a vehicle and executes a primary evaluation. An evaluation index of the primary evaluation includes a travel safety level of a travel to follow the primary candidate. The primary candidate having highest travel safety level is selected as at least one strong candidate of the target trajectory. If only one is selected as the strong candidate, the vehicle control system determines the selected strong candidate as a finalist candidate of the target trajectory. If two or more strong candidates are selected, the vehicle control system executes a secondary evaluation for the strong candidates to determine the finalist candidate. An additional evaluation index is used in the secondary evaluation.
