Abstract
A parking assistance system includes a vehicle control unit, a parking information storage unit, and a wheel stop position estimation unit. The vehicle control unit sets a contact assumption area (A) based on an estimated wheel stop position (Pc) estimated by the wheel stop position estimation unit, and performs pre-stop control for causing a vehicle to travel at a contact preparation speed in the contact assumption area (A). In a case where a parking space (E) in which the vehicle is to be parked is a registered parking space (Er), the vehicle control unit reduces the contact assumption area (A) to be smaller than in a case where the parking space (E) is not the registered parking space (Er).
Claims6
A parking assistance system that includes a vehicle control unit configured to control a driving force and a braking force acting on a wheel to perform vehicle control for moving a vehicle including the wheel to a parking space;
- the parking assistance system further comprising:
- a parking information storage unit configured to store information on a registered parking space that is a specified parking space registered in advance;
- and
- a wheel stop position estimation unit configured to estimate a position of a wheel stop in the parking space, wherein
- based on an estimated wheel stop position which is the position of the wheel stop estimated by the wheel stop position estimation unit, the vehicle control unit sets a contact assumption area, which is an area where the wheel is allowed to come into contact with the wheel stop, on a side of the vehicle relative to the estimated wheel stop position, and performs pre-stop control for causing the vehicle to travel at a preset contact preparation speed in the contact assumption area,
- the wheel stop position estimation unit estimates the position of the wheel stop using the information stored in the parking information storage unit when a target parking space that is the parking space in which the vehicle is to be parked is the registered parking space, and
- the vehicle control unit reduces the contact assumption area to be smaller in a case where the target parking space is the registered parking space than in a case where the target parking space is not the registered parking space.
