Patent number: 11702063Abstract: Since a maximum rotation speed of a second rotary machine is set to a lower value when a supercharging pressure is high than when the supercharging pressure is low, an engine torque decreases with an rotation speed of the second rotary machine which is relatively low and the rotation speed is less likely to fall into a high-rotation state. When the supercharging pressure is relatively low and the rotation speed is less likely to reach an upper-limit rotation speed of the second rotary machine, the maximum rotation speed is set to a relatively high value. Accordingly, the engine torque does not decrease to the rotation speed which is relatively high and power performance can be easily secured. As a result, it is possible to prevent a decrease in power performance due to the decrease in the engine torque and to prevent the rotation speed from falling into a high-rotation state.Type: GrantFiled: July 9, 2020Date of Patent: July 18, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Atsushi Tabata, Koichi Okuda, Tooru Matsubara, Yasuhiro Hiasa, Yasutaka Tsuchida

The first energy storage unit is controllable under a generator regime or a receiver regime. The supply voltage is adjusted, in the generator regime, by applying an algebraically additive supply voltage originating from the first electrical storage unit to the distribution, to maintain a supply voltage above a minimum threshold. In the receiver regime, if a surplus of supply voltage originating at least partially from a second storage unit in the generator regime is detected above the minimum threshold, this surplus is channeled energetically to the first energy storage unit of the vehicle if it is required for operating the vehicle and enables maintaining the supply voltage below a maximum threshold and above the minimum threshold.Type: GrantFiled: September 15, 2011Date of Patent: May 26, 2015Assignee: Siemens S.A.S.Inventors: Xavier Bavard, Eric Chattot, Jean-Noël Verhille

METHOD FOR DRIVING A HYBRID VEHICLE IN CONNECTION WITH START OF THE COMBUSTION ENGINE OF THE VEHICLE
Publication number: 20150142239Abstract: A method for driving a hybrid vehicle with a propulsion system including a combustion engine, an electric machine with a rotor and a stator and a planetary gear with three components including a sun gear, a ring gear and a planet wheel carrier, where an output shaft of the combustion engine is connected to a first component, an input shaft of a gearbox is connected to a second component and the rotor of the electric machine is connected to a third component. The vehicle is driven forward by the electric machine. The reverse gear engaged in the gearbox drives the third component of the planetary gear to rotate with a negative rotational speed while a brake brakes the first component. Thereafter, move the component brake to an open position, so that the output shaft of the combustion engine rotates with a positive rotational speed so that the combustion engine may be started.Type: ApplicationFiled: June 26, 2013Publication date: May 21, 2015Inventors: Niklas Pettersson, Mikael Bergquist, Johan Lindström, Anders Kjell, Mathias Björkman -

Publication number: 20150142229Abstract: Apparatuses, methods and systems for hybrid powertrain control are disclosed. Certain example embodiments control an internal combustion engine and a motor/generator of a hybrid electric powertrain. Example controls may determine a total output demanded of a powertrain based at least in part upon an operator input, a battery output target based upon a battery state of charge and independent of the operator input, and an engine output target based upon the total output demanded and the battery output target. Such example controls may further determine a constrained engine output target, a modified battery output target based upon the total output demanded and the constrained engine output target, and a constrained battery output target based upon the modified battery output target and a battery constraint. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and figures.Type: ApplicationFiled: November 21, 2013Publication date: May 21, 2015Applicant: CUMMINS INC.Inventors: Martin T.

Patent number: 9037330Abstract: A method for operating a hybrid vehicle comprises conducting unfire operation in an internal-combustion engine in a fuel cut-off mode during a hybrid-mode ride in deceleration of the internal-combustion engine, disconnecting the internal-combustion engine from an output while maintaining the fuel cut-off mode, and reducing a transmission capacity of a clutch configured to couple the internal-combustion engine and an electric motor. During a hybrid-mode ride in deceleration of the internal-combustion engine for transition to the purely electric drive, the internal-combustion engine may be disconnected from the output and shut down. When the internal-combustion engine is operated unfired in a fuel cut-off mode, the internal-combustion engine may be disconnected from the output and shut down by reducing the transmission capacity of the clutch that is connected between the internal-combustion engine and the electric motor.Type: GrantFiled: April 12, 2013Date of Patent: May 19, 2015Assignee: ZF Friedrichshafen AGInventors: Bernd Allgaier, Michael Gromus, Friedrich Tenbrock, Thomas Lemp
