Parking assist system

1. A parking assist system configured to execute automatic parking for autonomously moving a vehicle to a target position, the parking assist system comprising:

an acquiring unit configured to acquire surrounding information about surroundings of the vehicle;

a display unit configured to display the surrounding information acquired by the acquiring unit; and

a control unit configured to calculate a first target route to the target position based on the surrounding information acquired by the acquiring unit and to cause the vehicle to travel along the first target route,

wherein in a case where the acquiring unit acquires information about an obstacle on the first target route during traveling of the vehicle along the first target route and thus the vehicle stops traveling along the first target route, the control unit tries to calculate a second target route to the target position from a position where the vehicle stops traveling along the first target route, and

upon the control unit failing to calculate the second target route, in the case where the acquiring unit acquires the information about the obstacle on the first target route, and while a user is performing a brake operation of the vehicle, the control unit prohibits a notification about presence of the obstacle on the first target route.

2. The parking assist system according to claim 1 , wherein upon failing to calculate the second target route, the control unit gives the notification about the presence of the obstacle on the first target route at least on condition that the user is not performing the brake operation of the vehicle.

3. A parking assist system configured to execute automatic parking for autonomously moving a vehicle to a target position, the parking assist system comprising:

an acquiring unit configured to acquire surrounding information about surroundings of the vehicle;

a display unit configured to display the surrounding information acquired by the acquiring unit; and

a control unit configured to calculate a first target route to the target position based on the surrounding information acquired by the acquiring unit and to cause the vehicle to travel along the first target route,

wherein in a case where the acquiring unit acquires information about an obstacle on the first target route during traveling of the vehicle along the first target route and thus the vehicle stops traveling along the first target route, the control unit tries to calculate a second target route to the target position from a position where the vehicle stops traveling along the first target route,

upon failing to calculate the second target route, the control unit prohibits a notification about the automatic parking while a user is performing a brake operation of the vehicle and gives the notification about the automatic parking at least on condition that the user is not performing the brake operation of the vehicle,

upon failing to calculate the second target route, the control unit determines whether a non-performance period during which the user does not perform the brake operation of the vehicle continues for a prescribed period or more, and

upon determining that the non-performance period continues for the prescribed period or more, the control unit gives the notification about the automatic parking.

4. The parking assist system according to claim 3 , wherein upon determining that the non-performance period continues for the prescribed period or more, the control unit gives a promotion notification as the notification about the automatic parking, the promotion notification promoting the brake operation of the vehicle.

5. The parking assist system according to claim 4 , wherein in a case where the user performs the brake operation of the vehicle in response to the promotion notification, the control unit gives a resumption selection notification in which the user can select resumption of the automatic parking.

6. A parking assist system configured to execute automatic parking for autonomously moving a vehicle to a target position, the parking assist system comprising:

an acquiring unit configured to acquire surrounding information about surroundings of the vehicle;

a display unit configured to display the surrounding information acquired by the acquiring unit; and

a control unit configured to calculate a first target route to the target position based on the surrounding information acquired by the acquiring unit and to cause the vehicle to travel along the first target route,

wherein in a case where the acquiring unit acquires information about an obstacle on the first target route during traveling of the vehicle along the first target route and thus the vehicle stops traveling along the first target route, the control unit tries to calculate a second target route to the target position from a position where the vehicle stops traveling along the first target route,

upon failing to calculate the second target route, the control unit prohibits a notification about the automatic parking while a user is performing a brake operation of the vehicle,

upon failing to calculate the second target route, the control unit determines whether a non-performance period during which the user does not perform the brake operation of the vehicle continues for a prescribed period or more, and

in a case where the control unit determines that the non-performance period does not continue for the prescribed period or more and the acquiring unit stops acquiring the information about the obstacle on the first target route, the control unit resumes the automatic parking at least on condition that the user stops performing the brake operation of the vehicle.

7. The parking assist system according to claim 1 , wherein even if the control unit fails to calculate the second target route and the acquiring unit keeps on acquiring the information about the obstacle on the first target route, the control unit prohibits the notification about the presence of the obstacle on the first target route while the user is performing the brake operation of the vehicle.
