  • Patent number: 6344014
    Abstract: In an apparatus for controlling a starting clutch of a vehicle having a function of stopping engine idling so that an engine is automatically stopped, the starting clutch being provided in a transmission of the vehicle in series with a belt type continuously variable transmission mechanism, a load is applied to the transmission mechanism before a rise in a side pressure of the drive pulley and the driven pulley at the time of vehicle start-up from the state of engine stopping, resulting in a slipping of the belt. To avoid such a slipping, at the time of vehicle start-up from the state of engine stopping, the engaging force of the starting clutch is prevented from increasing above the creeping force which gives rise to the creeping of the vehicle until after a lapse of a predetermined time.

  • Patent number: 6344016
    Abstract: At the time of vehicle start-up from the state of engine stopping, a hydraulic oil pressure in a starting clutch sometimes overshoots beyond a creeping pressure as a result of a rise in the hydraulic oil pressure in the hydraulic circuit, resulting in shocks. A hydraulic oil pressure command value to a linear solenoid valve which controls the starting clutch pressure is made smaller than the creeping pressure until the point of time at which the rise in the hydraulic oil pressure in the hydraulic circuit (=the point of time at which a condition of F2=1 is satisfied). Once a discrimination of a rise in the hydraulic oil pressure has been made, the command value is made higher than the creeping pressure for a predetermined period of time (i.e., for the period of YTM3−YTM3B1), and is thereafter made to the creeping pressure.

  • Patent number: 6342928
    Abstract: A receiver includes two input terminals. A VHF broadcast signal over a 6-MHz band channel is inputted through one input terminal, while an FM broadcast signal over an approximate 100-kHz band channel is inputted through the other input terminal. The other input terminal is connected with a trap circuit for band width reduction. This trap circuit causes attenuation in signal components over channels close to a desired channel except that over the desired channel with a band of approximately 100 kHz. An analog switch inputs selectively the VHF broadcast signal and the FM broadcast signal attenuated in the signal components to a tuning circuit having a tuning band width of approximately 6 MHz. When an FM broadcast signal is selected, an FM broadcast signal only over a desired channel is outputted from the tuning circuit.
