Patent ID: 10379004

Abstract:
To obtain vehicle speed deviation data for changeover between accelerator and brake properly with inclination of a standard mode. In technique of calculating a changeover vehicle speed deviation from accelerator to brake in driving vehicle along standard mode (target vehicle speed) of vehicle drive pattern defined by time and vehicle speed within range of predetermined vehicle speed and time deviations from standard mode, an inclination AB of the standard mode is calculated by approximate differentiation of vehicle speed at a judgment standard point A of a current time instant on standard mode, first inclination AB is multiplied by an accelerator-to-brake changeover time deviation preset value Δt−1, and the accelerator-to-brake changeover vehicle speed deviation from the judgment standard point A to a changeover judgment point E for changeover at the current time instant is calculated by addition of the product and an accelerator-to-brake changeover vehicle speed deviation preset value ΔV−1.
