A vehicle apparatus is provided to enable a clutch to be re-engaged without creating
a shock when there is rollback of the wheels, which are driven by an electric motor
via the clutch. The vehicle apparatus comprises a travel direction command determining
section, an electric motor counterelectromotive force detecting section and a wheel
rotational direction determining section. The travel direction command determining
section is configured to determine whether a forward travel command or a reverse
travel command has been issued. The electric motor counterelectromotive force detecting
section is configured to detect a counterelectromotive force of an electric motor
that drives a wheel of a vehicle. The wheel rotational direction determining section
is configured to determine whether the wheel is rotating in an opposite direction
to a vehicle travel direction command determined by the travel direction command
determining section, based on a determination that a polarity of the counterelectromotive
force detected by the electric motor counterelectromotive force detecting section
does not match the vehicle travel direction command determined by the travel direction
command determining section.
