Vehicle automatic deceleration control device
A vehicle automatic deceleration control device includes a driver imaging camera as a driver state detection device that detects a state of a driver and a control unit that automatically decelerates a vehicle at a predetermined deceleration to stop the vehicle by controlling a brake device when the driver is detected to be in a state in which the driver is unsuitable for driving. The control unit is configured to determine whether a road on which the vehicle is traveling is a motorway, set the predetermined deceleration to a first deceleration when the road is determined to be the motorway, and set the predetermined deceleration to a second deceleration that is higher than the first deceleration when the road is determined not to be the motorway.
1 . A vehicle automatic deceleration control device including a driver state detection device that detects a state of a driver and a controller configured to automatically decelerate a vehicle at a predetermined deceleration to stop the vehicle by controlling a brake device when the driver state detection device detects that the driver is in a state in which the driver is unsuitable for driving,
wherein the controller is configured to:
determine whether a road on which the vehicle is traveling is a motorway, set the predetermined deceleration to stop the vehicle to a first deceleration when the road is determined to be the motorway, and set the predetermined deceleration to stop the vehicle to a second deceleration that is higher than the first deceleration when the road is determined not to be the motorway, and
wherein the controller is further configured to:
determine whether a following vehicle is present behind the vehicle when it is determined that the road on which the vehicle is traveling is determined not to be the motorway; and
change a deceleration pattern of an automatic deceleration based on the predetermined deceleration when the following vehicle is determined to be present, compared to when the following vehicle is not present.
2 . The vehicle automatic deceleration control device according to claim 1 , wherein the controller is configured to increase the first deceleration from a minimum value to a maximum value, and the second deceleration is larger than the maximum value.
3 . The vehicle automatic deceleration control device according to claim 1 , wherein the controller is configured to, when the vehicle is automatically decelerated at the first deceleration, start blinking of a hazard lamp after the deceleration is started, and when the vehicle is automatically decelerated at the second deceleration, start the blinking of the hazard lamp at a start of the deceleration or before the start of deceleration.
