PROBLEM TO BE SOLVED: To perform control with the same operation feeling always independently of an environmental change and so forth, by performing automatic correction of the change of an output value of a current sensor by a working temperature and adjustment against the vibration of the current sensor by software. SOLUTION: In a processing under a normal working environment, whether a car body is at a stop is examined (#41), and if the car is at a stop, a corrected level value is computed (#42). Though the output of a current sensor is about 1V in an atmosphere controlled to a temperature 25 deg.C when a car is at a stop i.e., when a current is 0(A) it changes with the temperature in reality. Here, the difference between input values of the sensor under the normal working condition and at a state of 25 deg.C is computed to obtain a corrected level value. Whether this corrected level value is within a permissible range is examined (#43), and if it is not within the range, it is judged as unadjustable, and considered as an error of the current sensor. If it is within the range, the corrected level value is set in a memory (#44). |
