PARKING ASSIST SYSTEM

A parking assist system for a vehicle includes an environment information obtainer, a sufficient parking space setter, a parked-vehicle inter-space calculator, a parking capable space setter, and a parking assister. The environment information obtainer obtains environment information around the vehicle. The sufficient parking space setter sets a sufficient parking space for the vehicle by including a parking allowance width on each of left and right sides of the vehicle. The parked-vehicle inter-space calculator calculates a space between parked vehicles, based on the obtained environment information. The parking capable space setter compares the space between the parked vehicles with the sufficient parking space and, when determining the space between the parked vehicles is greater than or equal to the sufficient parking space, sets the space between the parked vehicles to be a parking capable space. The parking assister guides the vehicle to the parking capable space.
