A parking assistance apparatus comprising: an interface unit configured to receive at least one of brake operation input information, accelerator operation input information, or steering operation input information; and a processor configured to: set a target parking space based on information on the vehicle surroundings sensed by a sensor unit; design a parking path for directing a vehicle to the set target parking space; and perform the automatic parking function by performing control such that the vehicle follows the parking path, characterized in that the processor is further configured to: determine, when it is detected that there is an operation input through the interface unit, whether to release, pause or resume the automatic parking function by reflecting the detected operation input, and perform, if it is determined to resume the automatic parking function by reflecting the detected operation input and if the detected operation input is a brake operation input or an accelerator operation input, the automatic parking function by continuously correcting an automatic steering control value in consideration of the detected operation input such that the vehicle follows the parking path without changing the parking path. an interface unit configured to receive at least one of brake operation input information, accelerator operation input information, or steering operation input information; and a processor configured to: set a target parking space based on information on the vehicle surroundings sensed by a sensor unit; design a parking path for directing a vehicle to the set target parking space; and perform the automatic parking function by performing control such that the vehicle follows the parking path, set a target parking space based on information on the vehicle surroundings sensed by a sensor unit; design a parking path for directing a vehicle to the set target parking space; and perform the automatic parking function by performing control such that the vehicle follows the parking path, characterized in that the processor is further configured to: determine, when it is detected that there is an operation input through the interface unit, whether to release, pause or resume the automatic parking function by reflecting the detected operation input, and perform, if it is determined to resume the automatic parking function by reflecting the detected operation input and if the detected operation input is a brake operation input or an accelerator operation input, the automatic parking function by continuously correcting an automatic steering control value in consideration of the detected operation input such that the vehicle follows the parking path without changing the parking path. determine, when it is detected that there is an operation input through the interface unit, whether to release, pause or resume the automatic parking function by reflecting the detected operation input, and perform, if it is determined to resume the automatic parking function by reflecting the detected operation input and if the detected operation input is a brake operation input or an accelerator operation input, the automatic parking function by continuously correcting an automatic steering control value in consideration of the detected operation input such that the vehicle follows the parking path without changing the parking path.
