Publication number: 20160230821Abstract: In a coasting control process, an ECU increases line pressure PL of a hydraulic path to predetermined pressure P1 such that discharge pressure of an MOP becomes higher than that before a C1 clutch is disengaged at timing when an executing condition of coasting control is satisfied (time t=t1). According to such coasting control process, driving torque of the MOP increases, so that deceleration (deceleration G) caused by driving of the MOP by a drive wheel becomes larger than that in conventional coasting control in which the discharge pressure of the MOP is not increased. As a result, it is possible to inhibit a driver from feeling discomfort due to free-running feeling generated during the coasting control.Type: ApplicationFiled: February 5, 2016Publication date: August 11, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takuro MORINO, Yoshio ITO, Tomoaki YANAGIDA, Kenta KIMURA, Yu NAGASATO, Takuya HIRATA, Tomoe OSADA
