<P>PROBLEM TO BE SOLVED: To further surely limit the speed of a vehicle at the maximum speed, irrespective of the traveling resistance, in an automobile equipped with a power output device that can output power to a drive shaft which is connected to the vehicle shaft and in the control device of the automobile. <P>SOLUTION: Cruising torque Tcrs, necessary for a vehicle to cruise at a vehicle speed V, is calculated from the relationship between torque outputted to the drive shaft and the acceleration α of the vehicle, when the vehicle speed V from a vehicle speed sensor exceeds a vehicle speed that is lower than the maximum vehicle speed Vmax by a prescribed value K (S110); cruising torque Tcrs0 necessary for the vehicle to cruise at the maximum vehicle speed Vmax is set by adding the difference between traveling resistance R at the vehicle speed V and traveling resistance R0 at the maximum vehicle speed Vmax to the cruising torque Tcrs (S112); a cruising torque limit value Tlim is set so as to approach the cruising torque Tcrs0 as the vehicle speed V approaches the maximum vehicle speed Vmax (S114); and driver request torque Tr* is limited (S116). Since the gradient resistance and the air resistance at the vehicle speed V are contained in the cruising torque Tcrs0, the vehicle speed can further be surely limited, irrespective of the gradient resistance and the air resistance. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
