  • 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.

The ground contact section is determined with the use of the above thresholds, thereby being capable of performing the determination with high accuracy. Therefore, the road surface condition can be detected with high accuracy based on the ground contact section determined with high accuracy.

    Abstract: A method of controlling a ground vehicle includes providing the vehicle with a first sensor configured to detect a vehicle position, a second sensor configured to detect a driven path of the vehicle, and a controller. The method also includes obtaining, via the first sensor, a plurality of vehicle position coordinates during a time interval of a drive cycle, and calculating, via the controller, a first path curvature parameter based on the plurality of vehicle position coordinates. The method additionally includes obtaining, via the second sensor, a second path curvature parameter based on the driven path during the time interval. The method further includes comparing, via the controller, the first path curvature parameter to the second path curvature parameter, and in response to a difference between the second path curvature and the first path curvature exceeding a threshold, automatically operating the controller according to a diagnostic mode.

  • Patent number: 10501084
    Abstract: A vehicle control system includes an external recognition means, a limit-distance calculation means, a relative-speed calculation means, and a required detection distance calculation means. When it is determined that the detectable limit distance is smaller than the required detection distance, the driver is notified that the lane change cannot be performed. When it is determined that the detectable limit distance is larger than the required detection distance, an automatic lane change of the vehicle is performed. The limit-distance calculation means detects a plurality of objects, which are sequentially detectable from the vehicle, and, based on the objects, the detectable limit distance is set in a vicinity of a farthest object.

  • Patent number: 10479343
    Abstract: Methods and systems are provided for launching a vehicle in an electric-only mode of operation. In one example, a driveline operating method comprises engaging a parking pawl to an output shaft of a dual clutch transmission in response to a request to engine a vehicle into a parked state, and disengaging the parking pawl via rotating an engine via an integrated starter/generator in response to a request to propel the vehicle solely via power of an electric machine positioned downstream of the dual clutch transmission. In this way, the vehicle may be launched in the electric-only mode without activating the engine in a fueled mode of operation and then deactivating the engine, which may increase vehicle operator satisfaction and which may improve fuel economy.

  • Patent number: 10465614
    Abstract: Disclosed is a vehicle control device which is applied to a vehicle equipped with an engine (10) and an engine torque adjustment mechanism for adjusting an output torque (engine torque) of the engine (10). The vehicle control device comprises a PCM (50) configured, upon satisfaction of a condition that the vehicle is traveling and a steering angle-related value relevant to a steering angle of a steering device is increasing, to control the engine torque adjustment mechanism to reduce the engine torque so as to generate vehicle deceleration to control vehicle attitude. The PCM (50) is further configured to gradually ease the condition, as the number of times of combustion per unit time in the engine (10) becomes smaller.
