Abstract: <P>PROBLEM TO BE SOLVED: To provide a signal generating circuit capable of generating a signal in response to a state of multiple kinds of received pulse signals without increasing the circuit scale and to provide a fail-safe circuit.  <P>SOLUTION: When the fail-safe circuit receives a vehicle-speed pulse from a vehicle speed detection section 3 or a periodic pulse from a microcomputer 5, a transistor Tr 31 is turned on every occasion, electric charges in a capacitor C31 are all discharged via a resistor R33 and the transistor Tr 31. When the transistor Tr 31 is turned off, electric charges are charged to the capacitor C31 via resistors R31, R32. When the charging continues for a permissible period or over, a voltage charged in the capacitor C31 reaches a switching voltage to change a state signal led to an IG cancel circuit 9 into an active level. The permitting period is set according to the vehicle-speed pulse whose normal maximum pulse interval is greater to allow a charge / discharge circuit 13 to be able to accept the vehicle-speed pulse and the periodic pulse in common.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Device for detecting fault of electric power steering device

IPC: H02P29/00
Filed: 2003-08-25
Abstract: <P>PROBLEM TO BE SOLVED: To surely detect the ON fault of the switching circuit of the H bridge of an electric power steering device.  <P>SOLUTION: If any of first to fourth switching elements 46a-46d of the H bridge circuit 41 has an ON fault, a high-voltage terminal TH and a low-voltage terminal TL short-circuit during a drive of a motor M, and a real current detected by a shunt resistor 42 is increased, and the real current hunts by the feedback control to bring this real current into conformity with a target current. So, this fault detector accumulates times, when the real current became larger than its upper limit value within a specified time and times when it became its lower limit value, and decides the occurrence of hunting, in short, the ON fault of the switching element, based on both accumulated times. Hereby, even in case the hunting real current within the ripple range of the real current at normal times, this discriminates between the ripple of the real current at normal times and the ripple of the real current at ON fault, whereby this can detect the ON fault of the switching element without fail.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
