Vehicle and control method

A vehicle comprising:

• a driving source;
• a rotation sensor that detects a rotational speed of the driving source;
• control circuitry configured to control the driving source;
• and
• an actuator that operates the driving source in accordance with a command given from the control circuitry, wherein:
• in response to the rotational speed of the driving source exceeding a preset upper threshold, the control circuitry executes suppression control that suppresses an outlet power of the driving source in comparison with before the rotational speed of the driving source exceeds the upper threshold;
• and
• in the suppression control, the control circuitry gives to the actuator a command that makes the power of the driving source suppressed in comparison with before the suppression control is executed, in accordance with an excess degree set in relation to an excess time period that is a time period in which the rotational speed of the driving source has exceeded the upper threshold.
