Patent number: 9236956Abstract: A frequency control apparatus includes: an input operation unit which detects a presence/absence of an input of a predetermined operation by an operator; and a control unit which, when the input of the predetermined operation by the input operation unit is detected, calculates radio frequencies, each of the radio frequencies being where a minimum value of differences with respect to multiplied frequencies of a current drive frequency of a device is less than or equal to a predetermined value, and which changes the current drive frequency of the device so that minimum values of differences between the calculated radio frequencies and multiplied frequencies of the changed drive frequency are greater than or equal to a predetermined value. The control unit changes the drive frequency to lessen a change width before and after the change by either increasing the drive frequency or decreasing the drive frequency.Type: GrantFiled: February 5, 2013Date of Patent: January 12, 2016Assignee: HONDA MOTOR CO., LTD.Inventors: Hirokazu Kanahara, Katsumi Kanasugi, Yoshihiro Mishio, Shinichi Arie

Patent number: 6717386Abstract: A rectifying section 2, and a DCDC converter 3 which lowers an input DC voltage and then outputs the voltage are disposed between an AC generator 1 and a load 4. When the output voltage Vt of the AC generator 1 is gradually lowered with starting from E0, the output power P is increased, and is maximum at Vt=V12. When the output voltage Vt is further lowered, the output power P is reduced. As an operating point at which the same output power P is obtained, there are a point of Vt=V11, and that of Vt=V13. The operation of the DCDC converter 3 is controlled so as to operate at the point of Vt=V13 where the output current I is lower.Type: GrantFiled: May 24, 2000Date of Patent: April 6, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Katsumi Kanasugi, Atsushi Kurauchi, Masaaki Hirose

Patent number: 6427108Abstract: A control system for an automatic vehicle transmission, in which the running resistance acting on the vehicle and the driving force generated by the vehicle are calculated, and a slope of a road on which the vehicle travels is estimated based on at least the calculated running resistance and the driving force. The vehicle running state is then discriminated by comparing the estimated slope with a predetermined value. The maximum driving force to be generated by the vehicle at the current gear ratio is calculated to determine a driving force difference from the calculated driving force and the gear ratio of the transmission is determined such that the driving force difference is a predetermined value in response to the discriminated running state, thereby enhancing the drivability.Type: GrantFiled: July 16, 1999Date of Patent: July 30, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Katsumi Kanasugi, Satoru Hiraki, Shuji Nagatani
