Device and method for controlling vehicle based on passage of bump of road

A device for controlling a vehicle, comprising:

• an acquirement unit configured to acquire accelerations of front and rear wheels of the vehicle;
• a determination unit configured to:
• determine whether (1) the acceleration of the front wheel is outside an acceleration range and (2) the acceleration of the front wheel fluctuates in a range wider than the acceleration range within a first maximum time period starting from a time at which the acceleration of the front wheel departs from the acceleration range;
• determine that the front wheel is passing a bump of a road in response to determining that (1) the acceleration of the front wheel is outside the acceleration range and (2) the acceleration of the front wheel fluctuates in the range wider than the acceleration range within the first maximum time period;
• and
• determine whether (1) the acceleration of the rear wheel is outside the acceleration range and (2) the acceleration of the rear wheel fluctuates in a range wider than the acceleration range within a second maximum time period starting from a time at which the acceleration of the rear wheel departs from the acceleration range;
• and
• determine that the rear wheel is passing the bump in response to determining that (1) the acceleration of the rear wheel is outside the acceleration range and (2) the acceleration of the rear wheel fluctuates in the range wider than the acceleration range within the second maximum time period;
• and
• a control unit configured to control, in response to the determination unit determining that the front wheel has passed the bump and the rear wheel is passing the bump, a drive unit of the vehicle to control a power source of the vehicle,
• wherein, to control the power source of the vehicle, the control unit is configured to restrain an output of the power source of the vehicle from being reduced.
