Title: Running controller for vehicle and method therefor
Inventor: WATANABE TAKAYUKI
IPC: B60W40/105
Filed: 2007-08-03
Abstract: <P>PROBLEM TO BE SOLVED: To achieve optimum running control even when a sensor of wheel speed or the like fails.  <P>SOLUTION: This running controller for vehicle calculates (a value of a solid line in (a)) front wheel average wheel speed larger than rear wheel average wheel speed as actual vehicle speed V<SB>ΔV</SB>for calculating a vehicle speed difference equivalent driving force instruction value α<SB>ΔV</SB>on and after a point A wherein a right rear wheel speed sensor falsely outputs a smaller value than a true value. The running controller for vehicle calculates (a value of the dotted line in (b)) actual vehicle speed V<SB>S</SB>for calculating a running resistance equivalent driving force instruction value α<SB>S</SB>from the rear wheel average wheel speed smaller than a front wheel average wheel speed. As a result, a total driving force instruction value α is reduced (a value of the dashed line in (e)) only by reduction of the running resistance equivalent driving force instruction value α<SB>S</SB>from the true value.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Title: Motor current reconstruction via dc bus current measurement
Inventor: HO EDDY YING YIN
IPC: H02P7/00
Filed: 2007-08-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a technology for reconstructing phase currents based on the measurement of a DC bus current.  <P>SOLUTION: Non-observable regions of DC bus current samples to reconstruct phase currents are reduced in size by using two phase space vector modulation. The non-observable regions can be further reduced by omitting dead time insertion for switch actuation when an output current is higher than a given threshold. Voltage command vectors in the non-observable regions can be formed of two additive vectors of different phases and magnitudes, to obtain a phase current which reflects an observable DC bus current. The additive vectors have the same combined time average value as that of the voltage command vector.  <P>COPYRIGHT: (C)2008,JPO&INPIT
