ACCELERATION RESTRICTION DEVICE FOR VEHICLE AND ACCELERATION RESTRICTION METHOD FOR VEHICLE

摘要

Provided are an acceleration restriction device for a vehicle and an acceleration restriction method for a vehicle that minimize decreases in drivability during the parking of a vehicle while making it possible to restrict acceleration during erroneous acceleration operation. An overall degree of certainty indicating the overall degree of certainty for the degree of certainty for a parking space and the degree of certainty for entry into the parking space is calculated on the basis of a degree of certainty for a parking space indicating the degree of certainty that a parking space is present in the travel direction of a vehicle and a degree of certainty for entry into the parking space indicating the degree of certainty that the vehicle will enter into the parking space. The higher the degree of overall certainty, the more the acceleration of the vehicle is restricted, said acceleration being controlled in accordance with the operation amount of an acceleration pedal that is operated by the driver and that indicates drive force. When detecting the degree of certainty for a parking space, processing is performed on the basis of an overhead image (environment) of the area surrounding the vehicle (V) and the vehicle speed (travel state) of the vehicle (V) in order to determine whether a line that is included in the overhead image and that is determined as possibly forming a parking space conforms to a condition for a line that forms an H-shaped parking space.
