Vehicular acceleration suppression device and vehicular acceleration suppression method
First Claim
1. A vehicular acceleration suppression device for suppressing acceleration of a vehicle which depends on a manipulation amount of a drive force instruction manipulation element manipulated by a driver to instruct a drive force to control suppression of the drive force, the vehicular acceleration suppression device comprising:
- a drive force manipulation amount detection unit configured to detect a drive force manipulation amount which is the manipulation amount of the drive force instruction manipulation element;
an acceleration control unit configured to control the acceleration of the vehicle depending on the drive force manipulation amount detected by the drive force manipulation amount detection unit;
a surrounding environment recognition unit configured to recognize an environment surrounding the vehicle based on detection information of a surrounding environment recognition sensor provided on the vehicle;
a vehicle travel direction detection unit configured to detect a travel direction of the vehicle;
a parking frame certainty degree calculation unit configured to calculate a parking frame certainty degree indicative of a degree of certainty about a presence of a parking frame in the travel direction of the vehicle based on the environment recognized by the surrounding environment recognition unit; and
an acceleration suppression unit configured to suppress the acceleration controlled by the acceleration control unit based on the parking frame certainty degree calculated by the parking frame certainty degree calculation unit and the travel direction detected by the vehicle travel direction detection unit, whereinthe acceleration suppression unit is configured to decrease a suppression degree of the acceleration depending on the travel direction detected by the vehicle travel direction detection unit.

Abstract
Based on a parking frame certainty degree indicative of a degree of certainty about a presence is a parking frame in the travel direction of the vehicle and a parking frame entering certainty degree indicative of a degree of certainty about whether the vehicle enters the parking frame, a total certainty degree indicative of a total degree of the certainty of the parking frame certainty degree and the parking frame entering certainty degree is calculated. Acceleration of the vehicle is controlled depending on a manipulation amount of an accelerator pedal manipulated by a drive to instruct a driving force and is suppressed in a lower suppression degree when the total certainty degree is lower than when the total certainty degree is higher. Furthermore, the acceleration of the vehicle is suppressed in the suppression degree decreased depending on the travel direction of the vehicle.
