Patent number: 9413525Abstract: A frequency tracking loop receives a result from a phase detector that detects an advance and a retard of a phase between input data and an extracted clock signal, and conducts a control to reduce a frequency deviation between the input data and the extracted clock signal. A phase interpolator adjusts a phase of the clock signal subjected to spread-spectrum frequency modulation on the basis result of the frequency deviation in the frequency tracking loop, and outputs the extracted clock signal. In the frequency tracking loop, the frequency deviation between the data signal and the clock signal is corrected to offset a variation of the frequency of the clock signal, on the basis of the frequency modulation information related to the clock signal subjected to the spread-spectrum frequency modulation which is input to the phase interpolator. The frequency of the clock signal seemingly follows the frequency of the data signal.Type: GrantFiled: May 29, 2015Date of Patent: August 9, 2016Assignee: Renesas Electronics CorporationInventor: Masahiro Takeuchi

Publication number: 20160052511Abstract: A control device for a hybrid vehicle includes a push-start mode and a motor start mode. The push-start mode transmits a driving force from driving wheels to the engine via a first transmission route at a speed detected by a speed detection means equal to or more than a predetermined speed to start the engine. The motor start mode starts the engine using a driving force of the motor at a speed equal to or less than the predetermined speed as well as in a stopped state. At a speed outside a speed range that either mode is executable when a start command of the engine occurs in driving only using the electric motor as the driving source, a control means performs the driving force reduction control for reducing a driving force transmitted from the electric motor to the driving wheels of the vehicle.Type: ApplicationFiled: April 11, 2014Publication date: February 25, 2016Applicant: HONDA MOTOR CO., LTD.Inventors: Masahiro TAKEUCHI, Atsushi IZUMIURA, Masanori MATSUSHITA
