  • Patent number: 11958471
    Abstract: A four-wheel drive vehicle includes: a drive-power distribution device for distributing a drive power from an engine to main and auxiliary drive wheels with a drive-power distribution ratio between the main drive wheels and auxiliary drive wheels; and a control apparatus for controlling an electric motor such that the drive-power distribution ratio becomes a target distribution ratio value, by setting an electric-current command value for driving an electric motor. The control apparatus is configured, in a drive-power transmitted state in which the drive power is transmitted to the drive-power distribution device, to execute a command-value reduction control operation for causing the electric motor to be driven with the electric-current command value being set to a value smaller than in a drive-power non-transmitted state in which the drive power is not being transmitted to the drive-power distribution device.

  • Patent number: 11959448
    Abstract: Systems and methods for determining whether to use engine start-stop systems during trail or other off-road driving are provided. Systems and methods may utilize various vehicle sensors (e.g., lidar, forward-facing cameras, accelerometers, sonar sensors, etc.) to detect when it is appropriate to command engine stop for fuel economy while driving off-road. To determine appropriateness, the vehicle may evaluate obstacles, ground clearance, and/or vehicle inclination. A method may include measuring accelerations/inclinations of a vehicle, comparing an acceleration value of each acceleration to an acceleration threshold, and disabling a start-stop system of the vehicle based on at least one acceleration value exceeding the acceleration threshold.
