Patent JP-H0739002-A (JP)
Title: Electric car controller
Inventor: WATAYA SEISHI
IPC: H02P29/00
Filed: 1993-12-20
Abstract: PURPOSE:To prevent a car runaway by stopping a motor drive through conversion and control of the power of a power source according to an accelerator opening degree while judging that something has failed, when a drive current fed to the drive motor of an electric car is larger than a current predetermined according to the accelerator opening degree. CONSTITUTION:An accelerator opening degree signal is input from a sensor 7 to an opening-degree-torque conversion memory 8 and opening-degree-current, conversion memory 11. A torque command is input to a function generator 9 from the conversion memory 8 to drive an inverter main circuit 2, which drives a motor 3 by converting a DC power source 1 into a three-phase VVVF. The conversion memory 11 stores an output current corresponding to an opening-degree signal. An output of the DC power source 1 is detected with a DC output sensor 10 and compared with an output of the conversion memory 11. When it is larger than the output of the conversion memory 11, a comparator 12 will issue a failure signal to an arithmetic circuit 13, which will stop the operation of the inverter main circuit 2 to de-energize an exciting coil 4a for a contactor 4, thereby preventing car runaway.
