Abstract
A target turn vehicle speed setting device for setting a target turn vehicle speed according to the corner radii obtained from external information. A reference radius used for setting the target turn vehicle speed is set to a minimum value of the corner radii of points included in a corner successively obtained from the external information. When the values of the corner radii of the points decrease, the update of the reference radii is started. When the values of the corner radii increase, the update of the reference radii is ended. The target turn vehicle speed can be more appropriately determined.
Claims12
A target turning vehicle speed setting apparatus for setting a target turning vehicle speed based on a corner radius obtained from external information, the apparatus comprising:
- an input unit that receives external information including a corner radius in front of a vehicle from an outside;
- and
- a control unit that sets a target turning vehicle speed based on the corner radius received by the input unit, wherein
- when the control unit sets the target turning vehicle speed a reference radius is set to a minimum value of values of the corner radius at a plurality of points included in a corner obtained from the external information at any time,
- the control unit starts an update of the reference radius when the value of the corner radius at the plurality of points included in the corner obtained from the external information at any time decreases, and
- the control unit finishes the update of the reference radius when the value of the corner radius at the plurality of points included in the corner obtained from the external information at any time increases.
A target turning vehicle speed setting method for setting a target turning vehicle speed based on a corner radius obtained from external information, the method comprising:
- receiving external information including a corner radius in front of a vehicle from an outside;
- and
- setting a target turning vehicle speed based on the received corner radius, wherein
- a reference radius when setting the target turning vehicle speed is set to a minimum value of values of the corner radius at a plurality of points included in a corner obtained from the external information at any time,
- wherein an update of the reference radius is started when the value of the corner radius at the plurality of points included in the corner obtained from the external information at any time decreases, and
- the update of the reference radius is finished when the value of the corner radius at the plurality of points included in the corner obtained from the external information at any time increases.
