摘要： A cruise control system for maintaining the speed of a vehicle at a fixed, set speed, comprising an actuator including an electric motor which actuates a speed control member via an electromagnetic clutch. To ensure the capability of the cruise control system to decelerate the vehicle even when it is traveling a steep and long downhill, and the normal operation of the cruise control system becomes inadequate for curbing the excessive increase of the vehicle speed, the electromagnetic clutch is disengaged whereby the speed control member is returned to the position for maximum deceleration. Since the operation of the cruise control system is not canceled even when the vehicle speed is increased substantially beyond the set speed, the cruise control system can readily return to its normal operation even after the vehicle is accelerated from the state of cruise control by stepping on the accelerator pedal, for instance for passing another car. To avoid frequent activation of the electromagnetic clutch, there may be defined an intermediate speed range in which a boosted deceleration signal is supplied to the electric motor for a deceleration action which is more boosted than a normal deceleration signal.

摘要： A vehicle cruise control system, comprising a control circuit for producing a control signal for maintaining a speed of a vehicle at a fixed level according to a difference between an actual vehicle speed and a target vehicle speed, and a drive circuit for producing a drive signal for selectively driving an actuator in a direction either to accelerate the vehicle or to decelerate the vehicle according to the control signal from the control circuit. The drive circuit is provided with a transistor bridge circuit comprising four drive transistors for producing the drive signal. The control circuit is provided with a detection means for detecting an abnormal state of the system and an inhibiting means which brings at least one of the drive transistors into an non-conductive state when any abnormal state is detected by the detecting means. The control circuit may be programmed to perform a certain diagnostic procedure for testing the soundness of the drive transistors. Thus, erratic behavior of the cruise control system and destruction of the drive transistors can be effectively prevented.

摘要： A vehicle cruise control system having an electric actuator for acting upon a throttle valve of a vehicle, a clutch for disconnecting the actuator from the throttle valve, a spring or the like for returning the output end of the clutch to a neutral state and a limit switch for detecting the limit of the motion of the output end of the clutch and discontinuing the supply of electric current to the actuator upon detection of the limit. Since the detection of the lower limit of the stroke of the actuator for decelerating the vehicle is necessary for preventing unnecessary supply of electric current to the actuator and overloading of the actuator, the closed state of the limit switch is tested by supplying an electric current to the actuator so as to decelerate the vehicle prior to starting the normal operation of the vehicle cruise control and determining if the electric current is indeed conducted through the actuator or not.

摘要： The present invention relates to a control system for an engine driven generator, and more specifically, to a control system for controlling the field current to the field coil of the generator to prevent a rapid decrease in the engine rotational speed throughout a transient period when an electric load, such as a head light or an air conditioner, is switched on and begins to draw current.In one embodiment of the invention, the control system comprises digital control means for repeatedly alternating throughout the transient period between calculating an on period and switching the field current on for the on period, and then calculating an off period and switching the field current off for the off period. The digital control means also detects a high output torque operating condition of the engine, and when such a condition is present, switches the field current on throughout the entire transient period.In a second embodiment of the invention, the control system comprises analog or "hard-wired" control means for performing the same functions as the digital control means.

摘要： An idling speed control system for controlling idling rotational speed of an internal combustion engine. A vacuum-operated actuator having a diaphragm defining a vacuum chamber controls opening and closing of a throttle valve in response to pressures supplied from a change-over control valve to the vacuum chamber. The change-over control valve selectively supplies the vacuum chamber with a first control pressure for opening the throttle valve and a second control pressure for closing same. An electronic control unit generates an on-off control pulse signal having a pulse repetition period corresponding to rotational speed of the engine, one of on-period or off-period of the on-off control pulse signal having a predetermined constant value, and supplies the change-over control valve with the on-off control pulse signal. A valve opening-correcting device is operatively connected to the throttle valve and responsive to at least one predetermined external load applied on the engine for correcting to a larger opening the opening of the throttle valve which is determined by the change-over control valve in response to the on-off control pulse signal.

摘要： An idling speed control system for controlling idling rotational speed of an internal combustion engine. A vacuum-operated actuator having a diaphragm defining a vacuum chamber controls opening and closing of a throttle valve in response to first and second control pressures supplied from a change-over control valve to the vacuum chamber. An electronic control unit generates, in response to an on-off control pulse signal having a period corresponding to rotational speed of the engine, one of on-period and off-period of the on-off control pulse signal having a predetermined constant value, and supplies the change-over control valve with the control pulse signal. Preferably, a detector is connected to the electronic control unit for detecting a change in the magnitude of a load on the engine and supplying the electronic control unit with an output signal indicative of the detected change in the load magnitude. The electronic control unit is responsive to the output signal for setting the pulse duration of the on-off control pulse signal to a value different from the above predetermined constant pulse duration. A delay valve provided across a passage connecting between the vacuum chamber and the change-over control valve sets the feeding speed of the first control pressure and that of the second control pressure fed through the passage to different values from each other.

摘要： Method for controlling an oxygen concentration sensor for sensing an oxygen concentration in an exhaust gas of an internal combustion engine, which sensor includes an oxygen pump element and a heater element, comprises steps for controlling a pump current and a heat current control in response to a result of a detection of engine load. When the engine is operating in a predetermined high load range, the supply of the pump current to the oxygen pump element is stopped, and the heat current to the heater element is reduced when the engine operation in the high load range has continued for more than a predetermined time period. The heater current to the heater element is stopped when the engine load is in a first predetermined load range, and when the engine operation in a second load range which is lighter than the first load range has continued for a predetermined time period.
