IPC: B60L3/00
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To provide a highly safe controller for driving electric vehicle which can stop motor drive by surely detecting the turning-off of an ignition key. SOLUTION: When an ignition key is 'OFF' at the logic level inputted to a microcomputer, the increment of an IGOFF(ignition off) counter is made and, when the key is 'ON' at the logic level, the increment of an IGON(ignition on) counter is made. Set values for discriminating the 'ON' and 'OFF' are set in advance in the counters and the 'ON' and 'OFF' of the ignition key are decided at the logic levels matching the set values. In this case, the ratio between the set values becomes a condition for discriminating the 'OFF' and, when it is discriminated that the ignition key is 'ON', both the IGON and IGOFF counters are cleared and the 'ON/OFF' level is decided in the shortest time.

Title: Method and device for controlling concentration of nitrogen oxide and for denitration
Inventor: WATANABE KO
IPC: B01D53/56
Filed: 1993-12-14
Abstract: PURPOSE:To prevent a frequently occurring abnormal alarm of NOx concentration and to control NOx concentration of mean value per unit time after denitration reaction of gas to be treated at the value not exceeding the regulatory value. CONSTITUTION:An NOx concentration signal inputted to an alarm 7 corresponds to the transit means NOx concentration D of (y) minute (y<60). Therefore, instantaneous peak NOx concentration measured by an NOx analyzer 2 is lowered and the frequency of generating an alarm is lowered. Further NOx concentration-controlling set value C for the remaining (60<x) minute is obtained from the transit means NOx concentration B for (x) minute (x<60). Since a device is operated at control value in which the transit mean NOx concentration for 60 minutes does not over control value A, operation for strictly keeping the regulatory value of the mean NOx concentration for 60 minutes is enabled. When the transit mean NOx concentration for (x) minute overs the control value A, calculation is performed by a computing element 10 and an excess amount of ammonia is temporarily injected. The NOx concentration after denitrating treatment of gas to be treated is avoided from being abnormally increased.
