摘要： PURPOSE:To prevent malfunctioning of a window which detects if it has caught something in it outside a detectable range by detecting the opening/closing position of the window from a count of pulse outputs for detecting the rotary angle of a motor, and controlling the detection of anything caught in the window within a predetermined range. CONSTITUTION:The position of a window pane 12 and the rotational frequency of a motor 3 are detected from the rotary pulse signal of a motor 3. In this case, when the gap H2 between the upper end of the window pane 12 and a window frame 14 is about 4 to 200mm and the window is being closed, it is determined whether or not anything is caught in the window according to change in the rotational frequency of the motor 3. When the window is being closed, i.e., when an ON signal is outputted from a first output terminal to turn on a relay, a main control circuit determines that something has been caught in the window. In that case, an ON signal is outputted also from a second output terminal to turn on the relay to operate a dynamic brake. Then an OFF signal is outputted from the first output terminal to stop the closing movement of the window pane 12. Then an ON signal is outputted from the second output terminal for a predetermined time even after the stopping of the closing motion, so as to cause the opening movement of the window pane 12 for a predetermined period.

摘要： PURPOSE:To enable the intermittent operation of a wiper at an appropriate intermittent time interval in traveling in a rainy weather in a daytime and night time respectively. CONSTITUTION:The vehicle signal, the intermittent operation signal from a wiper switch 3, and the headlight operation signal from a headlight switch 4 are received by a main control circuit 1, and a wiper motor 6 is selectively driven according to the output of the main control circuit 1. An intermittent time setting map for the daytime and that for the night time which is shorter than that for the daytime are prepared in the main control circuit 1, the day or the night is judged by the ON/OFF of the headlight switch 4, and the map is selected, and the wiper is intermittently operated by obtaining the intermittent time according to the vehicle speed. This constitution shortens the intermittent time preferably without using the manual operation against the interruption of the visibility due to the headlight by the other vehicle at night, and the intermittent operation of the wiper can be executed.

摘要： PURPOSE:To prevent the change of a control signal value by means of detection voltage from a potentiometer as against the difference of voltage inputted to the potentiometer. CONSTITUTION:The input terminal A1 of CPU 7 detects voltage Vo impressed on the resistance body VR of a throttle sensor 10, and detection voltage Vr fetched from the slider 10a of the throttle sensor 10 is detected by the input terminal A2 of CPU 7. CPU 7 calculates and obtains a control value theta by the throttle sensor 10 with a Vr to Vo ratio. A motor 1 is driven and controlled by using the control value theta. When input voltage Vo fluctuates, Vr is changed in proportional to said input voltage. Thus, effective control is realized without being affected by the fluctuation of input voltage Vo for the control value thetaobtained by the ratio of both values.

摘要： PURPOSE:To detect constant overload at all times without depending upon the magnitude of applied voltage in the detection of the overload of a motor. CONSTITUTION:A period tn is measured from pulses continuously generated with the revolution of a motor (ST1), and the next period tn+1 is measured when the next pulses are generated. A cycle is continued while the period tn+1 is used as a new one tn when the period tn+1 is smaller than a discrimination value consisting of the sum of the period tn and a value obtained by multiplying the square of the period tn by a constant B, and load is discriminated as overload and the motor is stopped when the period tn+1 is larger than the discrimination value (ST2-ST5). The constant B is acquired by multiplying each constant determined by the used motor by a coefficient correcting a delay by a mechanical time constant. Accordingly, overload can be discriminated by formula using the period without being converted into the number of revolution, thus simplifying processing, then allowing discrimination without being subject to the effect of voltage fluctuation.

摘要： PURPOSE:To bring an opening-closing body to a closed state without complicate operation by enabling the continuation of closing driving as it is even when the load of an actuator is to some extent increased. CONSTITUTION:The signals of the two systems of both Hall ICs 4, 5 are converted into motor rotational pulses by a motor rotational-pulse conversion circuit 6, and used for deciding the holding of a foreign matter by a main control circuit 1 as the rotary load of a motor. The signals of the two systems are input directly to the main control circuit 1, and the direction of rotation of the motor 3, the direction of the opening and closing of a window glass, is discriminated. When an opening-closing body is closed. a threshold and the load of an actuator are compared, and the opening-closing body is stopped and further opened and driven when the load of the actuator is larger than the threshold. When the opening-closing body is closed and operated by the working of a user, the threshold is to some extent increased, and closing driving can be continued as it is even when the load of the actuator is to some extent augmented, thus preventing the unnecessary stoppage of a body of revolution under an open state.

摘要： PURPOSE:To detect a constant overload at all times without being subject to the effect of the magnitude of applied voltage by discriminating load as overload when pulses are not generated next before a timer interrupt time passes after the time of the preceding generation of pulses. CONSTITUTION:When an interrupt signal is generated at an earlier time than pulses are generated, a period tn+1 based on the current generation of pulses is measured at the step ST6, and a step ST7 is returned to a step ST3 while using the period tn+1 as a pre-period tn in the next cycle at the step ST7. When current pulses are not generated when the interrupt signal is generated, load fluctuation reaches an overload level, and a step ST5 proceeds to a step ST8. Accordingly, the measured period is compared with a discriminating value multiplied by a coefficient read on the basis of a pre-period measured at a time before by one step and the pre-period from prepared map data, and overload is discriminated, thus allowing the detection of overload not affected by the fluctuation of the applied voltage of a motor.

摘要： PURPOSE:To prevent a motor driving level from becoming unstable at the time of starting a motor-driven vehicle. CONSTITUTION:The driver for a motor-driven vehicle of the type for outputting a drive duty signal to drive a motor only when the duty signal exceeds a certain predetermined value sets the predetermined value to a level of an upper limit predetermined value 22 when the signal is in a rising step and to a level of a lower limit predetermined value 23 when the signal is in a falling step. Accordingly, since hysteresis can be set to a predetermined value, even if the signal is varied within a hysteresis region 24, a motor does not repeat starting, slipping, etc.

摘要： PURPOSE:To indicate the residual capacity of a battery without being affected by a changed-over voltage of the battery, when the residual capacity of the battery of a device which conducts control by changing over the voltage of the battery in a plurality of stages in accordance with the state of operation is indicated by using a map. CONSTITUTION:In regard to a map for determining an output value for moving a pointer of a meter of the residual capacity of a battery in accordance with the residual capacity of the battery, a curve used at the time of running made by a relatively high battery voltage and shown by a solid line is changed over to a curve shown by an imaginary line of which the full scale is raised in relation to the one at the time of the running, when stopping is made by a relatively low battery voltage. Even when the battery voltage is changed over and varied, the meter of the residual capacity is made to conduct indication with the map changing for each battery voltage, and therefore proper indication can always be executed.
