<p><P>PROBLEM TO BE SOLVED: To provide a method for regulating the sliding speed of a vehicle when a slip occurs on an ascent slope. <P>SOLUTION: The method for regulating the vehicle includes a step of setting a brake torque Tb<SP>*</SP>so that the slip down speed of the vehicle becomes a predetermined vehicle speed by multiplying a torque insufficient, in a limited time motor torque Tm<SP>*</SP>to a balanced torque Tgrad corresponding to a road surface gradient guided from the relationship between an acceleration of the vehicle, and a torque output to the drive shaft by a ratio (reflecting ratioβ) responding to a vehicle speed V of a reverse direction (S118) when a slip occurs due to idling of the drive wheels on the ascent slope for limiting the motor torque Tm<SP>*</SP>required for the drive shaft connected to the drive wheel; and a step of operating the brake torque Tb<SP>*</SP>by a hydraulic brake mounted on a non-drive wheel different from the drive wheel (S130). As a result, the speed of the vehicle slipping down on a gradient by the limit of the motor torque Tm<SP>*</SP>can be regulated. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
