Patent number: 9523339Abstract: An engine starting apparatus includes a starter and a starter control unit configured to control driving of the starter. The starter control unit operates a motor with a pinion engaged with a ring gear to thereby crank an engine, and de-engage the pinion from the ring gear or de-energize the motor to thereby terminate the cranking of the engine. A cranking time from when cranking of the engine is initiated to when a predetermined engine speed equal to or greater than 450 rpm is reached is equal to or less than an acceptable limit of cranking time that does not provide, to a user of a vehicle, noticeable discomfort caused by cranking noise generated during the cranking of the engine.Type: GrantFiled: December 18, 2014Date of Patent: December 20, 2016Assignee: DENSO CORPORATIONInventors: Tatsuya Fujita, Mitsuhiro Murata

Patent number: 9488153Abstract: A method for operating a glow plug by means of pulse-width-modulated voltage pulses which are generated by controlling a load transistor, wherein a heating current flowing through the glow plug is measured and the duty cycle of the pulse-width-modulated voltage pulses is changed in accordance with values of the heating current. The heating current can be measured by means of a current measurement circuit, through which a sense current flows parallel to the load transistor, and the value of the heating current is calculated by multiplying a measured value of the sense current by a kILIS factor, wherein the temperature of the current measurement circuit is measured and the kILIS factor is defined in accordance with the measured circuit temperature. A glow plug control device is also disclosed.Type: GrantFiled: March 7, 2014Date of Patent: November 8, 2016Assignee: BorgWarner Ludwigsburg GmbHInventors: Andreas Bleil, Yasar Güncar, Markus Pados, Ralf Müller, Clemens Rinkert

Patent number: 9487208Abstract: A travel support device includes a mode planner that plans a travel mode that is to be one of an EV mode and an HV mode that uses at least an internal combustion engine as a drive source, for each of a plurality of sections, and an execution determiner that determines to execute a travel mode planning with the mode planner on condition that the total amount of consumption energy required for traveling the travel route is larger than an energy equivalent value that is obtained by adding a first allowance value to a remaining charge of the battery. In executing a planning based on the determination by the execution determiner, the mode planner executes the travel mode planning while assuming that energy from which energy corresponding to a second allowance value, which is smaller than the first allowance value is excluded is energy required for travelling the travel route.Type: GrantFiled: October 7, 2014Date of Patent: November 8, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yuki Ogawa

Patent number: 9481358Abstract: A starting method for starting an internal combustion engine of a hybrid vehicle involves detecting at least one engine related parameter to determine whether an electric machine is to be used for cranking the engine and opening the clutch to separate the electric machine from the engine. Subsequently, the at least one detected engine related parameter is used to select rotatable components to be used for assisting engine start. The selected components are rotated by connecting the countershaft to the clutch. The electric machine is operated. The clutch is then closed in order to start the engine.Type: GrantFiled: December 7, 2012Date of Patent: November 1, 2016Assignee: Volvo Truck CorporationInventor: Mattias Hansson
