Patent number: 10618512Abstract: System and methods are provided for improving fuel economy of a hybrid vehicle. A hybrid vehicle may include an EV driving mode, where the motor alone powers the hybrid vehicle. However, use of such a driving mode may be limited to conditions involving low drive force and power requests due to motor and battery power specifications. In some circumstances, the conditions during which the motor can be used to power the hybrid vehicle can be expanded. Such conditions may include instances where the driver only seeks light accelerations for a short period of time. Such an expanded EV mode may be triggered when the hybrid vehicle is travelling a downhill grade.Type: GrantFiled: August 4, 2017Date of Patent: April 14, 2020Assignee: TOYOTA MOTOR ENGINEERING & MANUFACTURING NORTH AMERICA, INC.Inventors: Thomas S.

Patent number: 9457667Abstract: A vehicle control device includes: an engine and a first motor generator from both of which a driving force for traveling is output to drive wheels; and an electricity storage device that storages electric power for driving the first motor generator. When a vehicle weight is in a reference state at a time of deceleration braking, the first motor generator is mainly caused, out of the first motor generator and the engine, to generate a braking force, and when the vehicle weight is greater than that in the reference state, the engine is mainly caused, out of the first motor generator and the engine, to generate the braking force. Thus, a sufficient braking force can be obtained while an input limit of the electricity storage device is prevented from being reached.Type: GrantFiled: December 14, 2011Date of Patent: October 4, 2016Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yukihiko Ideshio, Terufumi Miyazaki, Yuji Inoue, Shingo Eto, Yousuke Michikoshi, Akihiro Sato
