<P>PROBLEM TO BE SOLVED: To properly judge whether or not a vehicle stops. <P>SOLUTION: When it is judged that a vehicle stops on a load heater (S500, S510), a predetermined number of revolutions difference N2 which is relatively larger than that when the vehicle is judged not to stop is set as a threshold ΔNm2ref (S530). Then, a number of revolutions difference Δm2 between a detected number of revolutions Nm2det of a motor MG2 which is hardly affected by a magnetic field from the load heater and an estimated number of revolutions Nm2est of the motor MG2 estimated by using a detected number of revolutions Nrdet of a drive axle which is easily affected by the magnetic field and the threshold ΔNm2ref are used to judge whether or both detected number of revolutions Nm2det and Nrdet are normal or not. When it is judged that both of those detected number of revolutions are normal, whether or not the vehicle stops is judged by using the detected number of revolutions Nm2det, and when it is judged that at least one of those detected number of revolutions is not normal, whether or not the vehicle stops is judged by using the detected number of revolutions Nedet of the engine which is easily affected by the magnetic field. <P>COPYRIGHT: (C)2009,JPO&INPIT |
