Publication number: 20100057309Abstract: A control device for a vehicular automatic transmission which can realize a shifting with quickened response with suppressing a turbine blow-up during the shifting is provided. When a response in hydraulic pressure control by a hydraulic pressure control circuit 42 fails to satisfy a preset predetermined determining criterion, a shifting response is prevented from improving, in comparison to a case where the determining criterion is satisfied. Under a relatively low response of the hydraulic pressure control by the hydraulic pressure control circuit 42 due to air mixture to working oil, a control to inhibit a high-response shifting or the like is performed, so that a turbine blow-up caused by a delayed response of hydraulic pressure can be prevented. Thus, the control device for the vehicular automatic transmission can be provided, which can realize the shifting with quickened response, with suppressing the turbine blow-up during the shifting.Type: ApplicationFiled: September 2, 2009Publication date: March 4, 2010Applicant: Toyota Jidosha Kabushiki KaishaInventors: Keisuke OTA, Hitoshi MATSUNAGA, Koji OSHIMA

Publication number: 20100049411Abstract: A downshift allowable vehicle speed is variably set according to a torque converter slippage amount. Specifically, a downshift allowable vehicle speed is variably set by, using a reference downshift allowable vehicle speed when the torque converter slippage amount is 0 and a gear ratio of the automatic transmission after a downshift, calculating an allowable vehicle speed correction amount based on the present torque converter slippage amount and the gear ratio after the downshift, and setting a value obtained by subtracting the allowable vehicle speed correction amount from the reference downshift allowable vehicle speed as the downshift allowable vehicle speed. By such setting, it is possible to set a higher downshift allowable vehicle speed as the torque converter slippage amount becomes smaller, so it is possible to expand a downshift allowable region when the manual gearshift mode is selected.Type: ApplicationFiled: October 29, 2009Publication date: February 25, 2010Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hitoshi MATSUNAGA, Kei Kitajima
