Inventor: UECHI KENSUKE
IPC: B60L50/16
Filed: 2003-04-22
Abstract: <P>PROBLEM TO BE SOLVED: To drive a motor within the range of output limit on the supply side even at idling of a drive shaft caused by slippage or the like.  <P>SOLUTION: A future rotational number Nm2* of a motor MG2 is calculated using a phase advance element for taking detection delay in the rotation number of the motor MG2 into consideration (S170). A difference between an output limit Wout of a battery and a motor generation power Pm1* is divided with the calculated future rotational number Nm2*, to obtain a motor torque limit value Tmax (S180). The motor torque limit value Tmax is used to limit a torque command Tm2* of the motor MG2 (S190). Overdischarging of a battery is suppressed because the motor torque limit value Tmax is calculated based on the future rotational number Nm2* and the battery output limit Wout even if a drive wheel idles due to slippage or the like.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
