PURPOSE:To prevent the slip of a clutch and a belt by starting a timer without renewing the aimed value, judging the sensor trouble after the lapse of a prescribed time and controlling the line pressure, when ths anomaly output of a throttle sensor is outputted when the throttle opening degree is outside the upper and lower limit value range. CONSTITUTION:An ECU 82 calculates the aimed value of the line pressure from the signal of a throttle sensor 83, and memorizes the value as the aimed value in the preceding time. When the throttle sensor 83 outputs an anomaly signal in the case when the throttle opening degree is outside the upper and lower limit value range, the aimed value in the preceding time is used without renewing the aimed value, and a timer 84 is started. When the prescribed time lapses on the timer 84, ths sensor trouble is judged, and the line pressure is controlled with a previously set value, and the generation of slip of a clutch 62 and the belt 2A on a belt drive type continuously variable transmission 2 is prevented. Accordingly, the stable traveling feeling can be secured even if the throttle sensor is in anomaly. |
