PARKING ASSISTANCE DEVICE
First Claim
1. A parking assistance device that assists an operation of steerable wheels for causing a vehicle to enter or exit a parking space by automatic control of a steering device, the parking assistance device comprising:
- a path calculating section configured to calculate a moving path along which the vehicle moves to a target position;
a steered angle calculating section configured to calculate a target steered angle of the steerable wheels required for causing the vehicle to move along the moving path;
a steered angle detecting section configured to detect an actual steered angle of the steerable wheels; and
a control section configured to stop the operation of the steerable wheels under the automatic control when the target steered angle is an angle closer to a neutral angle than the actual steered angle and to perform the operation of the steerable wheels under the automatic control when the target steered angle is not an angle closer to the neutral angle than the actual steered angle.

Abstract
A parking assistance device assists the operation of steerable wheels for the entry of a vehicle into a parking space by the automatic control of a steering device. Upon execution of the automatic control, an entry path for moving the vehicle to the parking position is calculated, and also, a target steered angle for moving the vehicle along the entry path is calculated, and the actual steered angle is detected. If the target steered angle is an angle closer to the neutral angle than the actual steered angle, then the operation of the steering wheel through the automatic control is stopped. If the target steered angle is not at an angle closer to the neutral angle than the actual steered angle, then the operation of the steering wheel through the automatic control is executed.

5. A parking assistance device that assists an operation of steerable wheels for causing a vehicle to enter or exit a parking space by automatic control of a steering device, the parking assistance device comprising:
-
an angle sensor configured to detect an actual steered angle of the steerable wheels; and an electronic control unit, wherein the electronic control unit is configured to calculate a moving path along which the vehicle moves to a target position, calculate a target steered angle of the steerable wheels required for causing the vehicle to move along the moving path, stop the operation of the steerable wheels under the automatic control when the target steered angle is an angle closer to a neutral angle than the actual steered angle, and perform the operation of the steerable wheels under the automatic control when the target steered angle is not an angle closer to the neutral angle than the actual steered angle.
