Parking assist system
First Claim
1. A parking assist system which, after a vehicle has passed the side of a parking area formed between parked vehicles, assists parking of the vehicle from a stopped position of the vehicle to the parking area, the parking assist system comprising:
- a distance sensor that emits radio waves or ultrasonic waves and detects a distance to the parked vehicles based on reflected waves;
parking area detecting means that measures, when the vehicle passes the parked vehicles and a side of the parking area, the distance to the parked vehicles with the distance sensor and detects, after the vehicle has passed the side of the parking area, the parking area based on a measurement result from the distance sensor;
parking target position calculating means that calculates a parking target position of the vehicle based on the parking area that has been detected by the parking area detecting means; and
vehicle trajectory calculating means that calculates, based on the parking target position of the vehicle that has been calculated by the parking target position calculating means, vehicle trajectories from a stopped position where the vehicle has stopped to the parking target position.

Abstract
A parking assist system which, after a vehicle has passed the side of a parking area formed between parked vehicles, assists parking of the vehicle from a stopped position of the vehicle to the parking area, the parking assist system comprising: a distance sensor that emits radio waves or ultrasonic waves and detects the distance to the parked vehicles on the basis of the reflected waves; parking area detecting apparatus that measures, when the vehicle passes the parked vehicles and the side of the parking area, the distance to the parked vehicles with the distance sensor and detects, after the vehicle has passed the side of the parking area, the parking area on the basis of the measurement result; parking target position calculating apparatus that calculates a parking target position of the vehicle on the basis of the parking area that has been detected by the parking area detecting apparatus; and vehicle trajectory calculating apparatus that calculates, on the basis of the parking target position of the vehicle that has been calculated by the parking target position calculating apparatus, vehicle trajectories from a stopped position where the vehicle has stopped to the parking target position.

10. A parking assist system which, while a vehicle is passing or after the vehicle has passed a side of a parking area formed between parked vehicles, assists parking of the vehicle from a stopped position of the vehicle to the parking area, the parking assist system comprising:
-
parking area detecting means that detects, while the vehicle is passing the parking area, the parking area by receiving from a driver a position of at least one of first and second corner portions positioned on inner sides of two parked vehicles located on both sides of the parking area; parking target position calculating means that calculates a parking target position of the vehicle based on the parking area that has been detected by the parking area detecting means; and vehicle trajectory calculating means that calculates, based on the parking target position of the vehicle that has been calculated by the parking target position calculating means , vehicle trajectories on which the vehicle is moved directly backward from a stopped position where the vehicle has stopped and is then guided to the parking target position. - View Dependent Claims (11, 12, 13, 14, 15)
