  • Publication number: 20190128161
    Abstract: An exhaust purification system comprises an air-fuel ratio control device. If the air-fuel ratio detected by the downstream side air-fuel ratio sensor 41 reaches a second judged air-fuel ratio, the air-fuel ratio control device sets the target air-fuel ratio to a third set air-fuel ratio when the air-fuel ratio reaches the second judged air-fuel ratio, and switch the target air-fuel ratio from the third set air-fuel ratio to the second set air-fuel ratio when the air-fuel ratio becomes a value at the stoichiometric air-fuel ratio side from the second judged air-fuel ratio. The first set air-fuel ratio, the first judged air-fuel ratio and the second judged air-fuel ratio are an air-fuel ratio in the first region. The second set air-fuel ratio and the third set air-fuel ratio are an air-fuel ratio in a second region at an opposite side from the first region.

    Abstract: An exhaust purification system comprises a catalyst 20, an upstream side air-fuel ratio sensor 40, a downstream side air-fuel ratio sensor 41, and an air-fuel ratio control device. The air-fuel ratio control device alternately switches a target air-fuel ratio between a rich set air-fuel ratio and a lean set air-fuel ratio, calculates an oxygen storage amount and an oxygen discharge amount, updates a learning value, and corrects an air-fuel ratio-related parameter based on the learning value. The air-fuel ratio control device changes a condition for switching the target air-fuel, stores the learning value at the time when the operating state of the internal combustion engine changes from the first state to the second state as a first state value, and updates the learning value to the first state value when the operating state of the internal combustion engine returns from the second state to the first state.

  • Patent number: 10152935
    Abstract: R, G, and B are corrected according to a one-dimensional lookup table R_LUT, a one-dimensional lookup table G_LUT, and a one-dimensional lookup table B_LUT, respectively. W is corrected according to one-dimensional lookup tables W_LUT (R), W_LUT (G), and W_LUT (B). The extent of a contribution to post-correction tone values Rout, Gout, and Bout of each of tone values obtained from the former correction and tone values obtained from the latter correction is modified according to a color expressed by a group of pre-correction tone values Rin, Gin, and Bin. As the above-mentioned color is closer to white, the contribution to the tone values obtained from the latter correction increases.

  • Patent number: 10056853
    Abstract: Basic current commands of a d-axis and a q-axis are set based on a torque command of a motor. Subsequently, when the rotation speed of the motor is high, an electric angle compensation amount is set to be larger than that when the rotation speed of the motor is low, and a corrected predicted electric angle is set by adding the electric angle compensation amount to a predicted electric angle predicted from an electric angle based on a rotation position of a rotor of the motor from a rotation position detection sensor. Then, current commands of the d-axis and the q-axis are set by multiplying the basic current commands of the d-axis and the q-axis by a correction coefficient based on the corrected predicted electric angle, and an inverter is controlled using the current commands.

  • Patent number: 9815478
    Abstract: A driving assistance system includes a history storage unit, a behavior detecting unit, a state determining unit, and a notifying unit. The history storage unit stores a behavior history which is a past behavior history of a driver. The behavior detecting unit detects a current behavior of the driver. The state determining unit determines an unsafe state by comparing the transition of the behavior detected by the behavior detecting unit with the behavior history of the driver corresponding to a current driving path. If the state determining unit determines the unsafe state, the notifying unit gives notification to the driver.

  • Publication number: 20170274894
    Abstract: With a motor in rotation, 0 is set as each of a d-axis current command and a q-axis current command, and offset learning is carried out. Then, in carrying out offset learning, a transmission is controlled such that a shift stage of the transmission falls within a low vehicle speed-side predetermined shift stage range. Thus, the rotational speed of the motor can be more reliably made high to a certain extent, and offset learning can be carried out. As a result, the accuracy of offset learning can be restrained from decreasing.
