Publication number: 20200325867Abstract: A control system includes a controller. The controller estimates the swing-back amount indicating the turning amount of the crankshaft in the reverse rotation direction until the crankshaft stops. The controller calculates a stop-time counter value which is a value of a crank counter at the time when the engine is stopped based on a final counter value which is the value of the crank counter calculated last before the crankshaft stops and the estimated swing-back amount. The controller corrects the swing-back amount used for calculating the stop-time counter value based on a difference between the number of driving times calculated with reference to the map based on the calculated stop-time counter value and the value of the crank counter and the number of driving times calculated by increasing the number of driving times by one each time the high pressure system fuel pressure increases by the threshold or more.Type: ApplicationFiled: April 6, 2020Publication date: October 15, 2020Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Daiki KATO, Ryusuke KURODA, Masanao IDOGAWA

Publication number: 20200325833Abstract: A control system includes a controller. The controller counts the number of driving times of the high pressure fuel pump, which is the number of the reciprocating motions of the plunger based on a crank counter that is counted up at every predetermined crank angle. The controller stores a map in which a top dead center of the plunger is associated with a crank counter value, and store a crank counter value while an engine is stopped as a stop-time counter value. The controller calculates, referring to the map, the number of the crank counter values corresponding to the top dead center of the plunger between a crank counter value and the stop-time counter value, and set a calculated number as the number of driving times.Type: ApplicationFiled: April 7, 2020Publication date: October 15, 2020Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Daiki KATO, Ryusuke KURODA, Masanao IDOGAWA

Publication number: 20200325840Abstract: A control system includes a controller. The controller counts the number of driving times of a high pressure fuel pump, which is the number of reciprocating motions of a plunger based on a crank counter. The controller estimates a high pressure system fuel pressure based on the calculated number of driving times, a fuel temperature detected by a fuel temperature sensor, and a low pressure system fuel pressure detected by a low pressure system fuel pressure sensor when the high pressure system fuel pressure is not able to be acquired from a high pressure system fuel pressure sensor. The controller sets an opening period of an in-cylinder fuel injection valve based on the estimated high pressure system fuel pressure and to perform an engine start by an in-cylinder fuel injection when the high pressure system fuel pressure is not able to be acquired from the high pressure system fuel pressure sensor.Type: ApplicationFiled: April 2, 2020Publication date: October 15, 2020Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Daiki KATO, Ryusuke KURODA, Masanao IDOGAWA
