Vehicle control system

Abstract

To provide a vehicle control device enabling vehicle control to be easily permitted thereby enabling collision risk to be reduced when at least one of the condition of a driver and the travel state of a vehicle is in an abnormal state.SOLUTION: A vehicle control device performs vehicle control for reducing collision risk when an object having the collision risk of colliding with a vehicle is present. The vehicle control device prohibits execution of vehicle control when the operation of the driver related to the vehicle behavior satisfies predetermined prohibition conditions, permits execution of the vehicle control even if the prohibition conditions are satisfied when an acceleration operation to accelerate the vehicle satisfies predetermined permission conditions, and facilitates satisfaction of the permission conditions when both the condition of the driver and the travel state of the vehicle are in a normal state in a case where at least one of the condition of the driver and the travel state of the vehicle is in an abnormal state.SELECTED DRAWING: Figure 2

Claims

1. In a vehicle control device that performs vehicle control to reduce the risk of collision when there is an object that poses a collision risk with the vehicle, The aforementioned vehicle control device is If the driver's actions regarding the vehicle's behavior meet predetermined prohibition conditions, the execution of the vehicle control is prohibited. If the permit condition is met, and the duration of the state in which the amount of operation for acceleration to accelerate the vehicle is equal to or greater than a predetermined permit threshold operation amount is equal to or greater than a predetermined threshold time, then even if the prohibition condition is met, the execution of the vehicle control is permitted. If the mitigation condition is met, which is that at least one of the driver's condition and the vehicle's driving condition is abnormal, the permit condition is made more likely to be met than when the mitigation condition is not met. A vehicle control device configured as follows.

2. In the vehicle control device according to claim 1, The aforementioned vehicle control device is If the aforementioned simplification condition is met, the threshold time is made smaller than when the aforementioned simplification condition is not met. A vehicle control device configured as follows.

3. In the vehicle control device according to claim 2, The vehicle control device is configured to determine that the prohibition condition is met if the amount of operation is greater than or equal to a predetermined prohibition threshold amount, which is set to a value less than or equal to the permitted threshold amount of operation. Vehicle control device.

4. In the vehicle control device according to claim 1, The vehicle control device is configured such that when both the driver's condition and the vehicle's driving condition are abnormal, the permission condition is more likely to be met than when either the driver's condition or the vehicle's driving condition is abnormal. Vehicle control device.

5. In the vehicle control device according to claim 1, The aforementioned vehicle control device is If the driver is drowsy, unconscious, or having a seizure, it will be determined that the driver's condition is abnormal. If the vehicle is traveling outside its lane, traveling in the wrong direction in its lane, or traveling at a speed exceeding the speed limit, the driving condition is determined to be abnormal. A vehicle control device configured as follows.
