Abstract
A driving support device includes a determiner that determines that a driver of a mobile body is to be prompted to avoid contact with an object detected by an object detection device whose detection range includes at least an area toward which the mobile body advances by steering and determines a preferred steering direction for avoiding contact with the object and a controller that causes an actuator configured to be able to output a force to a steering operator to vibrate in the preferred steering direction at a frequency of 10 hertz or more and 30 hertz or less upon determining that the driver of the mobile body is to be prompted to avoid contact with the object by steering.
Claims7
A driving support device comprising:
- a storage medium configured to store computer-readable instructions;
- and
- a processor connected to the storage medium, the processor executing the computer-readable instructions to:
- determine that a driver of a mobile body is to be prompted to avoid contact with an object detected by an object detection device whose detection range includes at least an area toward which the mobile body advances by steering and determine a preferred steering direction for avoiding contact with the object;
- and
- cause an actuator configured to be able to output a force to a steering operator to vibrate in the preferred steering direction at a frequency of 10 hertz or more and 30 hertz or less by oscillating current flowing through the actuator between a first current value and a second current value upon determining that the driver of the mobile body is to be prompted to avoid contact with the object by steering, the first current value being determined based on a rating of the actuator, and the second current value being current for outputting a reactive force at a level that does not cause automatic steering by itself.
A driving support method comprising:
- by a driving support device, determining that a driver of a mobile body is to be prompted to avoid contact with an object detected by an object detection device whose detection range includes at least an area toward which the mobile body advances by steering and determining a preferred steering direction for avoiding contact with the object;
- and
- causing an actuator configured to be able to output a force to a steering operator to vibrate in the preferred steering direction at a frequency of 10 hertz or more and 30 hertz or less by oscillating current flowing through the actuator between a first current value and a second current value upon determining that the driver of the mobile body is to be prompted to avoid contact with the object by steering, the first current value being determined based on a rating of the actuator, and the second current value being current for outputting a reactive force at a level that does not cause automatic steering by itself.
A computer-readable non-transitory storage medium storing a program causing a processor of a driving support device to:
- determine that a driver of a mobile body is to be prompted to avoid contact with an object detected by an object detection device whose detection range includes at least an area toward which the mobile body advances by steering and determine a preferred steering direction for avoiding contact with the object;
- and
- cause an actuator configured to be able to output a force to a steering operator to vibrate in the preferred steering direction at a frequency of 10 hertz or more and 30 hertz or less by oscillating current flowing through the actuator between a first current value and a second current value upon determining that the driver of the mobile body is to be prompted to avoid contact with the object by steering, the first current value being determined based on a rating of the actuator, and the second current value being current for outputting a reactive force at a level that does not cause automatic steering by itself.
