Vehicle control system and vehicle control device for autonomous vehicle

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.

Vehicle control system

A vehicle includes an outside sensor configured to acquire information on an outside circumstance of the vehicle, a vehicle height adjusting device configured to adjust a vehicle height, and a control device configured to control the vehicle. The control device is configured to control the vehicle height adjusting device such that the vehicle height becomes a vehicle height corresponding to a platform condition at a predetermined stop position when the vehicle stops at the predetermined stop position. The control device is configured to control the vehicle height adjusting device based on a height of an obstacle such that the obstacle does not interfere with the vehicle when the obstacle is detected at the predetermined stop position by the outside sensor.

Vehicle and vehicle operating method

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.

Disclosed is a vehicle traveling controller that performs emergency evacuation traveling in the case of an emergency for proper traveling control. The vehicle traveling controller determines whether the vehicle traveling in accordance with a normal traveling rule is not dangerous and becomes proper traveling or not on the basis of environmental information around a vehicle (S), when it is determined that the vehicle traveling in accordance with the normal traveling rule becomes proper traveling, executes normal traveling control for instructing the vehicle to travel in accordance with the normal traveling rule (S), and when vehicle traveling in accordance with the normal traveling rule does not become proper traveling, executes emergency evacuation traveling control for instructing the vehicle to perform emergency evacuation traveling which is not in accordance with the normal traveling rule (S). Therefore, emergency evacuation traveling with high safety can be performed, as compared with vehicle traveling in accordance with the normal traveling rule, so the safety of vehicle traveling can be improved.

Vehicle traveling controller

A map information system includes a map database including map information; and a driving assist level determination device. The map information is associated with an evaluation value indicating a certainty of the map information for each location in an absolute coordinate system. Information indicating that the intervention operation is performed is included in driving environment information indicating a driving environment of a vehicle. The driving assist level determination device is configured to acquire, based on the driving environment information, intervention operation information indicating an intervention operation location where the intervention operation is performed, acquire, based on the map information, the evaluation value for each point or section in a target range, and determine, based on the evaluation value and the intervention operation location, an allowable level for each point or section within the target range.

Map information system

The vehicle control system includes a first controller configured to generate a target trajectory for the automated driving, and a second controller configured to execute vehicle travel control such that the vehicle follows the target trajectory. During the automated driving, the second controller controls a travel control amount which is a control amount of the vehicle travel control, acquire driving environment information, and execute preventive safety control for intervening in the travel control amount based on the driving environment information. The first controller includes a memory device in which information of an intervention suppression area is stored. When the vehicle travels in the intervention suppression area during the automated driving, the first controller outputs a suppression instruction for the preventive safety control to the second controller. And the second controller suppresses intervention of the travel control amount by the preventive safety control when the suppression instruction is received.

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.

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.

Vehicle traveling control system and vehicle control system

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.
