  • Patent number: 11609312
    Abstract: In a signal processing device, a branch section generates, from an input signal which is a current signal, a plurality of branch signals that are proportional to the input signal and have different signal intensities, and supplies the plurality of branch signals to respective different individual paths. A selection section selects one of the plurality of individual paths and outputs a signal supplied through the selected individual path. A determination section determines whether in each of the plurality of individual paths, a magnitude of a signal supplied to the selection section is in a preset allowable range. A control section causes the selection section to select the individual path having a highest gain among the individual paths in which the magnitude of the signal is determined by the determination section to be in the allowable range.

  • Patent number: 11603927
    Abstract: A shift range control apparatus controls a shift range switching system that switches shift ranges by controlling driving of a motor. This control apparatus calculates a motor angle based on a motor rotation angle signal, acquires an output shaft signal based on a rotation position of an output shaft from an output shaft sensor, sets a target rotation angle based on a target shift range and the output shaft signal, and controls driving of the motor such that the motor angle becomes the target rotation angle. The control apparatus sets the target rotation angle to a target limit value, in response to the target rotation angle that is set based on the output shaft signal being a value at which rotation occurs that is further toward a back side in a rotation direction than the target limit value that is set based on shift ranges before and after switching.

  • Patent number: 11603096
    Abstract: A traveling control apparatus performs a target-following control process on a target to be followed detected by a target detecting unit. Further, the traveling control apparatus calculates a probability that the target to be followed is within an own lane, and determines whether a degree of recognition by the target detecting unit of the target to be followed is in a weakly recognized state where the degree of recognition is weaker than a predetermined degree. The apparatus sets a reliability of the target to be followed on the basis of the probability calculated by a probability calculating process and a determination result by a determining process, and controls acceleration of an own vehicle so that a jerk which is a differential value of the acceleration becomes smaller as the reliability of the target to be followed is lower while the target-following control process is performed.
