  • Patent number: 10618368
    Abstract: A vehicle attitude control device includes a controller including a low-pass filter. The controller calculates a manipulated variable of the actuator that allows the roll of the vehicle to be suppressed. The controller processes the roll angle acceleration with the low-pass filter, integrates the roll angle acceleration in which a high-frequency component has been removed by the low-pass filter, and converts a roll angle velocity obtained by the integration, into the manipulated variable. The low-pass filter has a first vehicle speed-cutoff frequency characteristic in which a cutoff frequency becomes higher with increase in the vehicle speed, and the first vehicle speed-cutoff frequency characteristic is designed such that a peak frequency in roll vibration coincides with a local minimum roll frequency in wheelbase filtering, the roll vibration being amplified by a dead time and a phase delay in control by the controller.

  • Patent number: 9008934
    Abstract: When a vehicle travels, due to an input from a road surface to the front wheels and rear wheels of the vehicle, unsprung vertical accelerations are generated in unsprung portions of the vehicle. An electronic control unit detects such unsprung vertical accelerations. The electronic control unit calculates a front-back force generated at each of the wheels by use of the detected unsprung vertical acceleration, and estimates a front-back vibration generated in each of the wheels. The electronic control unit calculates a front-back vibration suppressing force for absorbing the front-back vibration by use of the detected unsprung vertical acceleration. The electronic control unit subtracts the calculated front-back vibration suppressing force from the calculated front-back force, and operates the in-wheel motors via an inverter, while controlling the output torques of the in-wheel motors. Thus, the front-back vibrations of the unsprung portions of the vehicle can be suppressed.

  • Patent number: 8583661
    Abstract: A route searching apparatus includes a travel route accumulation unit, an algorithm selection unit to select route searching algorithms to meet the preference of a user based on the accumulated travel routes, and a route searching unit to perform a route search up to a destination by using the selected algorithms. Preferably, the algorithm searching unit searches for each of the travel routes accumulated in the accumulation unit by means of several algorithms, calculates, for each algorithm, a match rate between the searched route and the actual travel route, and selects an algorithm of the highest match rate. Also, it is preferable that a condition common to roads avoided by the user is extracted from the accumulated travel routes, and a route search is performed by adjusting search costs so as to make such roads less prone to be selected.
