摘要： A drive control circuit sends out pulse signals of various pulse signals so as to control the light emission amount and luminance of LEDs by gradually increasing and decreasing the pulse width in predetermined cycles during predetermined periods based on parameters supplied from an LED drive controller that determine a first emission control processing period, a second emission control processing period, first to fourth slope periods and the like. The tone of an emitted color realized by a plurality of LEDs is controlled by synchronizing the periods of time of light emission control processings.

摘要： A power supply apparatus switchably operates an LDO regulator and a DC/DC converter connected in parallel so as to control a battery voltage Vbat from a power supply at a constant output voltage VO. A detected voltage Vs at a shared output terminal shared by the LDO regulator and the DC/DC converter is input to a feedback input terminal and fed back to the LDO regulator and the DC/DC converter. In order to suppress an undershoot occurring when switching from the LDO regulator to the DC/DC converter, a timing signal generating unit supplies a capability switching timing signal to a pre-drive circuit and switches the control capability of the DC/DC converter from a low capability mode at startup to a high capability mode.

In the disclosed embodiment, the judging unit judges that the present communication mode corresponds to the normal communication mode and sets operation conditions of the child station and the parent station to normal operation conditions so as to perform a communication between the child station and the parent station. Alternatively, the judging unit judges that the present communication mode corresponds to the low-power-consumption communication mode and sets operation conditions of the child station to a low-power-consumption operation condition.

摘要： A system and method for automatically controlling a vehicle speed to a desired cruise speed are disclosed in which in addition to a control unit and a throttle actuator through which an opening angle of an engine throttle valve is adjusted so that the vehicle speed detected by a vehicle speed sensor coincides with a target cruise speed set by a vehicle driver through a set switch, a vehicle speed determining circuit is provided for determining whether the vehicle speed detected by the vehicle speed sensor exceeds a lowest speed limit above which the cruse control by the control unit and throttle actuator becomes effective. When the vehicle speed is below the lowest speed limit, the power supply to the throttle actuator is interrupted so that the cruise control by means of the throttle actuator is cancelled.

摘要： A structure of a system for automatically controlling a vehicle speed to a desired cruise speed is disclosed in which, when a signal generated by a cancel switch provided for halting a control operation of the system, is generated by a turning on of the cancel switch, a voltage applying portion, intervened between the cancel switch and each signal lines connected between one of set/coast switch and acceleration/resume switch and a corresponding input end of a control circuit, generates a voltage whose level is different from that generated when either set/coast or acceleration/resume switch is operated, the voltage being supplied to each of the signal lines. A signal generating portion provides a third signal in response to the applied voltage from the voltage applying portion to another input end of the control circuit. Thus, the cancel switch signal can be distinguished and identified from the other switch signals derived from the set/coast and acceleration/resume switches even if one or all of the signal lines has failed.

摘要： A cruise control system for an automotive vehicle with a manual or automatic transmission, includes an inhibition circuit. The inhibiting circuit blocks communication between a power supply and an actuator and/or a controller when the manual transmission is set in a predetermined gear or when the automatic transmission is set in a driving range other than the drive range, so as to inhibit the controller from operating in the cruise control mode. When the vehicle is provided with an automatic transmission which is selectively set in first, second, third or fourth gear while the shift lever is set in the drive range position, the cruise control system includes a first inhibiting circuit which blocks the communication when the shift lever is set in a position other than the drive range position, and a second inhibiting circuit which blocks the communication when the automatic transmission is set in either the first or second range while the shift lever is set in the drive range position.
