  • Publication number: 20210139050
    Abstract: A target trajectory generation device generates and outputs target trajectories each including a target position and a target speed of a vehicle. A first target trajectory is intended to perform at least one of steering, acceleration, and deceleration of the vehicle. A second target trajectory is intended to decelerate and stop the vehicle. When a malfunctioning device does not exist, a vehicle traveling control device executes vehicle traveling control based on the first target trajectory. When the malfunctioning device exists, the vehicle traveling control device stops the vehicle by executing the vehicle traveling control based on the second target trajectory output before the malfunction occurs, or based on the second target trajectory output from the target trajectory generation device other than the malfunctioning device.

  • Patent number: 10991176
    Abstract: A driverless transportation system includes an autonomous driving vehicle and a management server. A check code includes: a vehicle code unique to the autonomous driving vehicle; and a passcode whose value changes each time it is generated. In deactivation processing, the autonomous driving vehicle newly generates the passcode, stores the check code including the newly-generated passcode, as a first check code, and transmits the first check code to the management server. The management server stores the first check code as a stored check code. In order to activate the autonomous driving vehicle, the management server transmits an activation instruction and the stored check code to the autonomous driving vehicle. In response to that, the autonomous driving vehicle reads the check code from its memory device, as a second check code, and determines whether or not the second check code and the stored check code match.

  • Publication number: 20210107528
    Abstract: 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.

  • 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: 20210107478
    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, the vehicle travel control device determines whether or not a cancellation condition is satisfied. When the cancellation condition is satisfied, the vehicle travel control device cancels both the first target trajectory and the second target trajectory, and decelerates the vehicle.
