Abstract
In a driving assistance device for a vehicle provided with an automatic driving mode and a manual driving mode, a standby member is provided to allow a driver seated at a seat to rest an arm. A sensor senses that a hand of a driver is placed at a position where the driver can reach the sensor while the driver rests the arm on the standby member. The sensor senses that a finger of the driver is in contact with the sensor. The sensor is provided in an arm rest.
Claims5
A driving assistance device for a vehicle provided with an automatic driving mode and a manual driving mode, the device comprising:
- an arm rest on which a driver seated at a seat rests an arm;
- a posture monitoring sensor including a hand sensor that senses whether a hand of the driver is placed at a position where the driver can reach the hand sensor while the driver rests the arm on the arm rest, the hand sensor being provided in the arm rest, the posture monitoring sensor being configured to determine whether the driver is in a predetermined posture defined by the hand of the driver being placed at the position;
- an information presentation interface including at least one of a speaker and a display, the information presentation interface being configured to
- in response to the hand sensor not sensing the hand at the position, start a timer that measures a period of time during which the hand sensor does not sense the hand in the automatic driving mode, and
- present alert information only in response to the period of time measured by the timer indicating a predefined period of time has elapsed, the alert information including a prompt for the driver to change a current posture of the driver to the predetermined posture;
- and
- a user control input device capable of changing a traveling track in the automatic driving mode, the user control input device being provided in the vicinity of the hand sensor, wherein
- the hand sensor surrounds the user control input device.
