摘要： A method and system for detecting a failure of an automatic transmission for a vehicle employing a speed shift range switch operation signal from a speed shift range switch as one of the control signals to control the automatic transmission. The method is carried out by: detecting a speed shift range from the speed shift range switch; generating a start signal indicating a starting state of a starter for expediting a start of an engine for the vehicle; and automatically controlling the automatic transmission so as to maintain the speed shift range in the case where "P" or "N" range is not detected when the start signal is "ON".

摘要： In case where an engine rotational detection signal from an ignition pulse generator is not appropriately detected even if an amount of induction air and a fuel injection amount are larger than predetermined values, an engine rotational signal failure is decided, and an automatic transmission is controlled in a state before the decision. Therefore, the automatic transmission control based on the engine rotational speed such as, for example, a speed shift control (ordinarily a shift control), a lockup control (ordinarily a lockup control, a smooth control), a line pressure control (ordinarily a line pressure control, a starting time control) can be appropriately controlled. Thus, the automatic transmission control can be executed based on the engine rotational speed. In case where any of the conditions of (1) when the cruise control signal is erroneously turned on in case where a vehicle speed is smaller than a value in the case of non operation of a cruise control, (2) when the cruise control signal which ought to be released is erroneously turned on at the time of turning a brake switch on, (l) when the cruise control signal is erroneously turned on in an "N" or "P" range, (4) when any of the paragraphs (1) to (3) is continued for a predetermined time, are satisfied, a failure of the cruise control set signal line is detected, and the automatic transmission control of the cruise control is prohibited. The normal state is recovered when an off signal of the cruise control set is detected in the above-described conditions. Accordingly, since a failure of the cruise control set signal line is reliably detected, the automatic transmission control is appropriately executed by using the cruise control signal. Thus, the automatic transmission control can be executed based on a cruise control signal.

摘要： A control system of a vehicular continuously variable transmission having a manual transmission mode comprises speed ratio changing when a manual transmission mode is chosen and a speed range is manually selected for changing a speed ratio of the selected speed range in the up-shift direction as the engine speed becomes high on the side of low speed ranges and in the down-shift direction as the vehicle speed becomes high on the side of high speed ranges. Further, in the manual transmission mode, when the engine speed reaches a lower limit value without making a down-shift, the speed ratio is controlled so as to hold the engine speed at the lower limit value. Thus constituted continuously variable transmission provides a vehicle with miscellaneous advantages such as an easy handling, smooth acceleration/deceleration performance, extended maximum speed and the like when the manual transmission mode is selected.
