CONTROLLER AND CONTROL METHOD

The present invention obtains a control apparatus and a control method capable of appropriately executing speed control based on positional relation information between a leaning vehicle and a target vehicle. [0002] In a control apparatus (20) and a control method according to the present invention, an executing section of the control apparatus (20) executes speed control in which a speed of a leaning vehicle (1) is controlled based on positional relation information between the leaning vehicle (1) and a target vehicle, a specifying section of the control apparatus (20) executes specifying processing in which the target vehicle is specified based on a detection result by a surrounding environment sensor (14) mounted to the leaning vehicle (1), and the specifying section changes the specifying processing based on speed information on the leaning vehicle (1).
