  • RPM calculating apparatus for controlling engine, capable of expanding high rpm region without changing calculation period
    Patent number: 6701275
    Abstract: In an engine-controlling rpm calculating apparatus, there are provided a rotary sensor for producing a detection pulse in response to an rpm related to the engine, and a microcomputer for calculating the rpm based upon the detection pulse so as to control the engine. The detection pulse contains a plurality of pulse series, and the microcomputer selects one pulse series from the plurality of pulse series in response to a drive region of the engine, and calculates the rpm related to the engine based upon both a detection time instant and the pulse number of the selected pulse series. As a result, the calculable high rpm region is expanded without changing the calculation time period, while the calculation capability of this rpm calculating apparatus with respect to the low rpm region is not deteriorated.

  • Automatic transmission controller having automatic-shifting-to-neutral control
    Patent number: 6542804
    Abstract: An automatic transmission controller having automatic-shifting-to-neutral control is provided, wherein automatic-shifting-to-neutral control is notified to a driver so as not give him a sense of incongruity and it is prohibited on a slope so as to prevent backward moving of a vehicle. In an automatic transmission controller having automatic-shifting-to-neutral control for shifting the automatic transmission to neutral when a vehicle is continuously stopped in an idling state for a predetermined time, the automatic transmission controller comprises automatic-shifting-to-neutral notifying/warning means for notifying the automatic-shifting-to-neutral state, slope detecting means for detecting that the vehicle is on a slope, and automatic-shifting-to-neutral control prohibiting means for prohibiting the automatic-shifting-to-neutral control when it is detected that the vehicle is on the slope.
