Parking assist apparatus

1. A parking assist apparatus for a vehicle, comprising:

a sensor configured to acquire vehicle peripheral information including information on an object present in a peripheral region of the vehicle;

an electronic control unit configured to, when an assist request is generated,

set a target position which is a position of the vehicle at a point in time at which the vehicle completes parking in a parking space or exiting from the parking space based on the vehicle peripheral information,

set, as a movement path, a path along which the vehicle is movable from a current position of the vehicle to the target position, and

determine movement assist information including steering angle information representing changes in a steering angle of the vehicle when the vehicle moves along the movement path; and

the electronic control unit configured to execute parking assist control such that the vehicle moves in accordance with the determined movement assist information, the parking assist control including steering angle control for changing the steering angle of the vehicle, driving force control for controlling a driving force of the vehicle, and braking force control for controlling a braking force of the vehicle,

wherein the electronic control unit is further configured to, when an occupant performs a predetermined first operation that is an operation to one of an accelerator pedal and a shift lever in a first time period,

apply the braking force to the vehicle to stop the vehicle, and

execute pause processing for maintaining the movement assist information, the first time period being a period from a first point in time at which the movement assist information is determined to a second point in time immediately before the vehicle has reached the target position.

2. The parking assist apparatus according to claim 1 , wherein the electronic control unit is configured to, when executing the pause processing, notify the occupant of a predetermined resume operation to be performed by the occupant for resuming the parking assist control, and

wherein the electronic control unit is configured to,

when the occupant performs the resume operation, resume the parking assist control in accordance with the movement assist information which has been maintained since the pause processing is started, and

when the occupant does not perform the resume operation in a time period from the notification of the resume operation until a predetermined time threshold elapses, erase the movement assist information which has been maintained since the pause processing is started, and terminate the parking assist control.

3. The parking assist apparatus according to claim 1 , wherein the electronic control unit is configured to, when the occupant performs a predetermined second operation in a second time period from a point in time at which the vehicle has reached the target position until a predetermined time has elapsed, terminate the parking assist control at a point in time at which the occupant performs the second operation, and

wherein the electronic control unit is configured to, when the occupant does not perform the second operation in the second time period, terminate the parking assist control at a point in time at which the second time period has elapsed.

4. The parking assist apparatus according to claim 3 , wherein the electronic control unit is configured to, when the occupant operates the accelerator pedal in the first time period, determine that the occupant performs the first operation, and

wherein the electronic control unit is configured to, when the occupant operates the accelerator pedal or the brake pedal in the second time period, determine that the occupant performs the second operation.

5. A parking assist apparatus for a vehicle, comprising:

a sensor configured to acquire vehicle peripheral information including information on an object present in a peripheral region of the vehicle;

an electronic control unit configured to, when an assist request is generated,

set a target position which is a position of the vehicle at a point in time at which the vehicle completes parking in a parking space or exiting from the parking space based on the vehicle peripheral information,

set, as a movement path, a path along which the vehicle is movable from a current position of the vehicle to the target position, and

determine movement assist information including steering angle information representing changes in a steering angle of the vehicle when the vehicle moves along the movement path; and

execute parking assist control such that the vehicle moves in accordance with the determined movement assist information, the parking assist control including steering angle control for changing the steering angle of the vehicle, driving force control for controlling a driving force of the vehicle, and braking force control for controlling a braking force of the vehicle,

wherein the electronic control unit is further configured to, when an occupant performs a predetermined operation that is an operation to one of an accelerator pedal and a shift lever before the vehicle reaches the target position, apply the braking force to the vehicle to stop the vehicle and pause the parking assist control.

6. The parking assist apparatus according to claim 5 , wherein the electronic control unit is configured to, when an occupant performs the predetermined operation serving as a first operation in a first time period, execute pause processing for maintaining the movement assist information, the first time period being a period from a first point in time at which the movement assist information is determined to a second point in time immediately before the vehicle has reached the target position.

7. The parking assist apparatus according to claim 6 , wherein the electronic control unit is configured to, when executing the pause processing, notify the occupant of a predetermined resume operation to be performed by the occupant for resuming the parking assist control, and

wherein the electronic control unit is configured to

when the occupant performs the resume operation, resume the parking assist control in accordance with the movement assist information which has been maintained since the pause processing is started, and

when the occupant does not perform the resume operation in a time period from the notification of the resume operation until a predetermined time threshold elapses, erase the movement assist information which has been maintained since the pause processing is started, and terminate the parking assist control.

8. The parking assist apparatus according to claim 6 , wherein the electronic control unit is configured to, when the occupant performs a predetermined second operation in a second time period from a point in time at which the vehicle has reached the target position until a predetermined time has elapsed, terminate the parking assist control at a point in time at which the occupant performs the second operation, and

wherein the electronic control unit is configured to, when the occupant does not perform the second operation in the second time period, terminate the parking assist control at a point in time at which the second time period has elapsed.

9. The parking assist apparatus according to claim 8 , wherein the electronic control unit is configured to, when the occupant operates the accelerator pedal in the first time period, determine that the occupant performs the first operation, and

wherein the electronic control unit is configured to, when the occupant operates the accelerator pedal or the brake pedal in the second time period, determine that the occupant performs the second operation.
