  • Patent number: 8738229
    Abstract: A current command value computing section includes an integration control computing section. Based on an integration of the steering torque ?, the integration control computing section computes a steering torque integration control amount Iint*, which is a compensation component for increasing the assist force. The integration control computing section functions as a determining device that determines whether the vehicle is traveling forward in a straight line. When the determining device determines that the vehicle is traveling forward in a straight line, the integration control computing section outputs the steering torque integration control amount Iint* to an adder. The current command value computing section superimposes the steering torque integration control amount Iint* on a basic assist control amount Ias* computed by a basic assist control section, and outputs the obtained value, as a current command value Iq* corresponding to a target assist force, to an output section.

    Abstract: A steering torque shift control amount calculation unit (31) calculates the steering torque shift control amount (?ts) by multiplying the basic shift amount (?ts_b) used as the basic compensation component by the transition coefficient (Kss). Then, the steering torque shift control amount (?ts) is subjected to the low-pass filter process in an abrupt change prevention processing unit (32). An abrupt change prevention processing unit (40) is provided in the steering torque shift control amount calculation unit (31). The transition coefficient (Kss) is subjected to the low-pass filter process in the abrupt change prevention processing unit (40). The cutoff frequency of the low-pass filter that forms the abrupt change prevention processing unit (40) is set to a value lower than the cutoff frequency of the low-pass filter that forms the abrupt change prevention processing unit (32) that executes the low-pass filter process on the torque shift control amount (?ts).

  • Patent number: 8362405
    Abstract: A reference heater energization delay time is established according to an engine conditions (shift range, cooling water temperature, intake-air temperature, ambient temperature, and oil temperature) during starting period. An extension delay time is established according to an engine condition after starting period. A final heater energization delay time is established by adding the extension delay time to the reference heater energization delay time. Until an elapsed time after starting period of engine reaches the final heater energization delay time, an energization of a heater of an exhaust gas sensor is inhibited. When the elapsed time after starting period of engine reaches the final heater energization delay time, the energization of the heater is started to heat a sensor element.
