Acceleration suppression apparatus
Provided is an acceleration suppression apparatus having improved practicality. The acceleration suppression apparatus includes: an in-vehicle sensor ( 20 ) configured to acquire information relating to a position of an own vehicle and information relating to an operation of an operating element of the own vehicle to output the acquired information; and a parking assist ECU ( 10 ) configured to execute, based on the information acquired from the in-vehicle sensor ( 20 ), acceleration suppression control for suppressing acceleration of the own vehicle by controlling at least one of a drive device ( 30 ) or a braking device ( 40 ) mounted on the own vehicle. The parking assist ECU ( 10 ) is configured to execute the acceleration suppression control when, in a situation in which the own vehicle is positioned in a predetermined region including a parking space, a traveling mode of the own vehicle matches a predetermined mode defined in advance as a traveling mode when the own vehicle is being parked in the parking space.
1. An acceleration suppression apparatus, comprising:
an in-vehicle sensor configured to acquire information relating to a position of an own vehicle and information relating to an operation of an operating element of the own vehicle to output the acquired information; and
a processor configured to:
execute, based on the information acquired from the in-vehicle sensor, acceleration suppression control for suppressing acceleration of the own vehicle by controlling at least one of an actuator or a brake mounted on the own vehicle;
execute the acceleration suppression control when, in a situation in which the own vehicle is positioned in a predetermined region including a parking space, a traveling mode of the own vehicle matches a predetermined mode defined in advance as a traveling mode when the own vehicle is being parked in the parking space;
store a distribution map of a direction in which the own vehicle is advancing when the own vehicle is being parked in the predetermined region and a speed of the own vehicle in the predetermined region, the distribution map being a map indicating the direction and the speed of the own vehicle at predetermined time points;
execute the acceleration suppression control when at least one of a current direction in which the own vehicle is advancing and a current speed of the own vehicle which are acquired from the in-vehicle sensor are included in a predetermined range of the distribution map; and
generate the distribution map based on a history of the direction in which the own vehicle is advancing in the predetermined region and the speed of the own vehicle traveling in the predetermined region.
2. The acceleration suppression apparatus according to claim 1 , wherein the distribution map is a map in which a vertical axis corresponds to a north-south direction, a horizontal axis corresponds to an east-west direction, and a distance from an origin corresponds to the speed of the own vehicle.
3. The acceleration suppression apparatus according to claim 1 , wherein the in-vehicle sensor is further configured to acquire the information relating to the operation of the direction and the speed of the own vehicle when the own vehicle is advancing in a forward direction.
4. An acceleration suppression method, comprising:
acquiring information relating to a position of an own vehicle and information relating to an operation of an operating element of the own vehicle; and
permitting, based on the information acquired, suppression of acceleration of the own vehicle by controlling at least one of an actuator or a brake mounted on the own vehicle, the permitting of suppression of acceleration being executed when, in a situation in which the own vehicle is positioned in a predetermined region including a parking space, a traveling mode of the own vehicle matches a predetermined mode defined in advance as a traveling mode when the own vehicle is being parked in the parking space;
storing a distribution map of a direction in which the own vehicle is advancing when the own vehicle is being parked in the predetermined region and a speed of the own vehicle in the predetermined region, the distribution map being a map indicating the direction and the speed of the own vehicle at predetermined time points;
executing the acceleration suppression control when at least one of a current direction in which the own vehicle is advancing and a current speed of the own vehicle which are acquired from the in-vehicle sensor are included in a predetermined range of the distribution map; and
generating the distribution map based on a history of the direction in which the own vehicle is advancing in the predetermined region and the speed of the own vehicle traveling in the predetermined region.
5. A non-transitory computer-readable storage medium having stored thereon a computer program which, when executed, implements a method comprising:
acquiring information relating to a position of an own vehicle and information relating to an operation of an operating element of the own vehicle; and
permitting, based on the information acquired, suppression of acceleration of the own vehicle by controlling at least one of an actuator or a brake mounted on the own vehicle, the permitting of suppression of acceleration being executed when, in a situation in which the own vehicle is positioned in a predetermined region including a parking space, a traveling mode of the own vehicle matches a predetermined mode defined in advance as a traveling mode when the own vehicle is being parked in the parking space;
storing a distribution map of a direction in which the own vehicle is advancing when the own vehicle is being parked in the predetermined region and a speed of the own vehicle in the predetermined region, the distribution map being a map indicating the direction and the speed of the own vehicle at predetermined time points;
executing the acceleration suppression control when at least one of a current direction in which the own vehicle is advancing and a current speed of the own vehicle which are acquired from the in-vehicle sensor are included in a predetermined range of the distribution map; and
generating the distribution map based on a history of the direction in which the own vehicle is advancing in the predetermined region and the speed of the own vehicle traveling in the predetermined region.
