Abstract:
Grade resistance Ri is calculated based on a driving force, an acceleration degree and rolling/air resistance. When a brake switch is OFF, a down-slope is judged using the grade resistance Ri directly as a value Rif for down-slope judgment. On the contrary, when braking is performed where the brake switch is ON, a minimum value of the grade resistance Ri is peak held, to set the peak held value as the value Rif for down-slope judgment.
