A vehicle comprising: a first driving source and a second driving source (130, 135, 160) configured to generate driving power for running the vehicle (100, 100A); and a control device configured to control the first and second driving sources (130, 135, 160), the control device configured to: cause the vehicle (100, 100A) to run while (i) causing driving power variation operation to be performed on the first driving source in which the first driving source is switched between a first state where the first driving source generates driving power of a first level and a second state where the first driving source generates driving power larger than the driving power in the first state, and (ii) causing driving power variation operation to be performed on the second driving source in which the second driving source is switched between a third state where the second driving source generates driving power of a second level and a fourth state where the second driving source generates driving power larger than the driving power in the third state, characterized in that the control device is further configured to cause the first driving source to be switched between the first state and the second state so as to maintain a speed of the vehicle (100, 100A) within an acceptable range, while the driving power variation operation is performed on the first and second driving sources. a first driving source and a second driving source (130, 135, 160) configured to generate driving power for running the vehicle (100, 100A); and a control device configured to control the first and second driving sources (130, 135, 160), the control device configured to: cause the vehicle (100, 100A) to run while (i) causing driving power variation operation to be performed on the first driving source in which the first driving source is switched between a first state where the first driving source generates driving power of a first level and a second state where the first driving source generates driving power larger than the driving power in the first state, and (ii) causing driving power variation operation to be performed on the second driving source in which the second driving source is switched between a third state where the second driving source generates driving power of a second level and a fourth state where the second driving source generates driving power larger than the driving power in the third state, characterized in that the control device is further configured to cause the first driving source to be switched between the first state and the second state so as to maintain a speed of the vehicle (100, 100A) within an acceptable range, while the driving power variation operation is performed on the first and second driving sources. cause the vehicle (100, 100A) to run while (i) causing driving power variation operation to be performed on the first driving source in which the first driving source is switched between a first state where the first driving source generates driving power of a first level and a second state where the first driving source generates driving power larger than the driving power in the first state, and (ii) causing driving power variation operation to be performed on the second driving source in which the second driving source is switched between a third state where the second driving source generates driving power of a second level and a fourth state where the second driving source generates driving power larger than the driving power in the third state, characterized in that the control device is further configured to cause the first driving source to be switched between the first state and the second state so as to maintain a speed of the vehicle (100, 100A) within an acceptable range, while the driving power variation operation is performed on the first and second driving sources.
