Abstract
An automatic driving vehicle is running in an automatic driving mode effected by a driving control device. An operator is able to instruct via a SLOW DOWN button on a touch panel that the automatic driving vehicle is to be decelerated or stopped. Should any anomaly occur to the SLOW DOWN button, a message or the like is displayed on a touch panel to encourage operation of an emergency stop switch. When the operator operates the emergency stop switch, emergency stop control is executed.
Claims5
An automatic driving control system, comprising:
- an automatic driving control device for controlling running of an automatic driving vehicle in an automatic driving mode;
- a deceleration operation device for receiving an operation from an operator while the automatic driving vehicle is running in the automatic driving mode to instruct the automatic driving control device to decelerate or stop the automatic driving vehicle;
- an emergency stop operation device provided separately from the deceleration operation device to receive an operation by the operator to instruct an emergency stop;
- and
- a transmission device for conducting a transmission for encouraging the operator to operate the emergency stop operation device when an anomaly occurs to the deceleration operation device,
- wherein:
- running control by the automatic driving control device is invalidated and control for an emergency stop is conducted when the emergency stop operation device instructs an emergency stop;
- when the emergency stop operation device is operated, running control by the automatic driving control device is invalidated after elapse of a first period of time when a behavioral stability of the automatic driving vehicle during deceleration is a first stability;
- the running control by the automatic driving control device is invalidated after elapse of a second period of time that is shorter than the first period of time when the behavioral stability of the automatic driving vehicle during deceleration is a second stability;
- and
- an error in a speed, a posture and a position of the automatic driving vehicle during a process of stopping the automatic driving vehicle in the second stability is less than the error in the speed, the posture and the position of the automatic driving vehicle during the process of stopping the automatic driving vehicle in the first stability.
