Abstract
A parking assistance device according to the present disclosure includes a memory and a processor coupled to the memory. The processor is configured to: record a first path based on teacher traveling in which a vehicle moves from a parking position to a parking-lot-exiting position by manual driving of a driver; generate a second path for causing the vehicle to travel from a first position where the vehicle is positioned to a joining point onto the first path; and cause the vehicle to perform automated traveling from the first position to the parking position based on the first path and the second path.
Claims20
A parking assistance device, comprising:
- a memory;
- and
- a processor coupled to the memory and configured to:
- record a first path based on teacher traveling in which a vehicle moves from a parking position to a parking-lot-exiting position by manual driving of a driver;
- generate a second path for causing the vehicle to travel from a first position where the vehicle is positioned to a joining point onto the first path;
- estimate a first direction of the vehicle at a point on the first path when the vehicle has moved from the first position to the point;
- determine that the second path is generatable when a difference between the first direction and a second direction of the vehicle at the point in the teacher traveling is equal to or less than a prescribed threshold;
- and
- cause the vehicle to perform automated traveling from the first position to the parking position based on the first path and the second path.
A parking assistance method, comprising:
- recording a first path based on teacher traveling in which a vehicle moves from a parking position to a parking-lot-exiting position by manual driving of a driver;
- generating a second path for causing the vehicle to travel from a first position where the vehicle is positioned to a joining point onto the first path;
- estimating a first direction of the vehicle at a point on the first path when the vehicle has moved from the first position to the point;
- determining that the second path is generatable when a difference between the first direction and a second direction of the vehicle at the point in the teacher traveling is equal to or less than a prescribed threshold;
- and
- causing the vehicle to perform automated traveling from the first position to the parking position based on the first path and the second path.
A parking assistance method, comprising:
- recording a first path based on teacher traveling in which a vehicle moves from a parking position to a parking-lot-exiting position by manual driving of a driver;
- generating a second path for causing the vehicle to travel from a first position where the vehicle is positioned to a joining point onto the first path;
- and
- causing the vehicle to perform automated traveling from the first position to the parking position based on the first path and the second path,
- wherein the second path is generated when a difference between a first direction and a second direction is equal to or less than a prescribed threshold, the first direction being a direction of the vehicle at a point on the first path when the vehicle has moved from the first position to the point, the second direction being a direction of the vehicle at the point in the teacher traveling.
A parking assistance method of causing a vehicle to perform automated traveling based on teacher traveling implemented by manual driving of a driver, the parking assistance method comprising:
- recording a travel path based on the teacher traveling by the driver;
- causing the vehicle to perform automated traveling along the travel path from a current position of the vehicle to a parking position of the travel path;
- and
- when the current position of the vehicle is apart from the travel path, and a traveling direction of the vehicle is same as a traveling direction of the vehicle at a start position of the travel path, generating a path along which the vehicle performs the automated traveling from the current position to the parking position through the start position of the travel path.
