Vehicle control system
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.
1. A vehicle control system that controls a vehicle performing automated driving,
the vehicle control system comprising:
a vehicle travel control device configured to execute vehicle travel control that controls steering, acceleration, and deceleration of the vehicle such that the vehicle follows a target trajectory; and
an automated driving control device configured to generate a first target trajectory being the target trajectory for the automated driving of the vehicle, wherein
the vehicle travel control device is further configured to:
determine whether or not an activation condition of travel assist control is satisfied, wherein the travel assist control controls at least one of the steering, the acceleration, and the deceleration for at least one of improving safety or comfort of travel of the vehicle, and stabilizing behavior of the vehicle; and
when the activation condition is satisfied, calculate a travel assist control amount that is a control amount of at least one of the steering, the acceleration, and the deceleration required for the travel assist control,
when the activation condition is satisfied and the travel assist control amount is calculated in addition to the first target trajectory during the automated driving, the vehicle travel control device compares the first target trajectory and the travel assist control amount to determine, based on a relationship between the first target trajectory and the travel assist control amount, whether or not a cancellation condition for cancelling both the first target trajectory and the travel assist control amount is satisfied, and
when the cancellation condition is satisfied, the vehicle travel control device cancels both the first target trajectory and the travel assist control amount, and decelerates the vehicle.
