Alternatively, the output characteristic may be changed by, for example, multiplying the control arithmetic expression by a predetermined coefficient according to the seat position.
When the seat position is in the front position, a small occupant is assumed, so the output torque is made smaller than when the seat position is in an intermediate position behind the front position.
When the seat position is forward of a small occupant's sitting position L1 (first position), the controller 24 controls the vehicle output to be smaller than when the seat position is rearward of the seat position L1. .
In this embodiment, assuming that a small-sized passenger rides in the vehicle, the output of the vehicle is weakened, so that the passenger's sense of security can be increased.

Furthermore, another embodiment is described.
When the seat position is further rearward than the position where a large rider rides, the output torque is reduced in a rear-wheel drive vehicle.
In a rear-wheel-drive vehicle, when the seat position is behind the seating position L2 (second position) of a large passenger, the controller 24 controls the output of the vehicle to be greater than when the seat position is in front of the seating position L2. controlled to be small.
This is because, when the output is high with the occupant's center of gravity in the rear, the front wheels 13 tend to float, resulting in poor drivability.
