Abstract
A vehicle drive control apparatus is provided for detecting clutch trouble early and alert the driver to the need for clutch repair. The vehicle drive control apparatus is provided in a vehicle having a clutch disposed between an electric motor and a wheel driven by the electric motor. The drive control apparatus comprises a clutch control section and a diagnosis section. The clutch control section is configured to control engagement of the clutch to selectively drive the wheel by the electric motor. The diagnosis section is configured to diagnose whether or not the clutch can be operated by controlling the clutch control section to turn on and off the clutch, when the diagnosis section determines that the wheel is not being driven by the electric motor.
