Abstract:
1. A vehicle, comprising: a power source arranged to output driving power to a driveshaft linked with a drive wheel; a rotation speed detector structured to obtain a rotation speed of the driveshaft as a driveshaft rotation speed; an angular acceleration computation module configured to compute an angular acceleration of the drive wheel as a computed drive wheel angular acceleration from the obtained driveshaft rotation speed; a drive wheel rotation speed computation module configured to compute a rotation speed of the drive wheel as a computed drive wheel rotation speed from the obtained driveshaft rotation speed; an estimated vehicle body speed computation module configured to compute an estimated speed of a vehicle body as an estimated vehicle body speed by integration of an actual driving force actually used for driving the vehicle and the computed drive wheel angular acceleration; a slip detection module configured to detect occurrence or non-occurrence of a certain slip of the drive wheel, based on a rotation speed of the drive wheel expected from the estimated vehicle body speed and the computed drive wheel rotation speed; and a control module configured, in response to detection of non-occurrence of the certain slip by the slip detection module, to control the power source to output a driving force corresponding to a driving force demand required for driving and drive the vehicle with the output driving force, and in response to detection of the occurrence of the certain slip by the slip detection module, to control the power source to output a driving force corresponding to the driving force demand with drive restriction of the power source and drive the vehicle with the restricted output driving force.
