摘要： A power distribution apparatus for an electric vehicle includes a power distribution mechanism configured to distribute power output from an electric motor to front and rear wheels, and a controller configured to control the power distribution mechanism. The power distribution mechanism includes a first clutch configured to fix a power distribution ratio during straight traveling to a first distribution ratio at which first power distributed to the rear wheels and second power distributed to the front wheels are nearly same, and a second clutch configured to fix the power distribution ratio during straight traveling to a second distribution ratio at which the first power is larger than the second power. The controller is configured set the second clutch to an engaged state and sets the first clutch to a half-engaged state during regenerative braking.

摘要： A vehicle includes a first detector detecting first information related to a condition of a first road surface; a second detector contactlessly detecting second information related to a condition of a second road surface; and a controller controlling a driving force of the vehicle using a friction coefficient estimated based on the first and/or second information. A processor(s) of the controller execute(s) a process including: determining whether the conditions are of a same type based on the first and second information; when the conditions are of different types, controlling the driving force using a friction coefficient estimated based on the second information as a friction coefficient of the second road surface; and based on determining that the conditions are of the same type, controlling the driving force using a friction coefficient estimated based on the first information as the road surface friction coefficient of the second road surface.

摘要： A vehicle control device includes a behavior instability acquirer, an automated driving advisability determination unit, and a switching time setting unit. The behavior instability acquirer acquires behavior instability of a vehicle. The automated driving advisability determination unit determines whether to continue automated driving on the condition that the vehicle is performing the automated driving. On the condition that the automated driving advisability determination unit determines that the automated driving is noncontinuable, the switching time setting unit determines switching time from the automated driving to manual driving on the basis of the behavior instability.

摘要： A vehicle control apparatus to be applied to a vehicle includes a driver state-value detection processor, a road-surface-state detection processor, a threshold setting processor, a dangerous-driving determination processor, and a determination threshold changing processor. The driver state-value detection processor detects a state value of a driver who drives the vehicle. The road-surface-state detection processor detects a road-surface state of a road on which the vehicle is traveling. The threshold setting processor decides, based on the state value, one or more determination thresholds of a state to be determined as occurrence of dangerous driving. The dangerous-driving determination processor determines that the dangerous driving is occurring in a case where the state value is present within a range outside any of the one or more determination thresholds for a predetermined time period or more. The determination threshold changing processor changes the one or more determination thresholds based on the road-surface state.

摘要： A control apparatus for a vehicle includes: a first road surface friction coefficient calculator; a second road surface friction coefficient calculator; and a braking and driving force controller. The first road surface friction coefficient calculator calculates a first road surface friction coefficient that is a friction coefficient of a road surface in a contact with a wheel. The second road surface friction coefficient calculator calculates a second road surface friction coefficient on a basis of a detection value from a contactless sensor that contactlessly detects a road surface state.

摘要： A control device of a vehicle includes a motor controller. The motor controller is capable of controlling a motor configured to generate a driving force of the vehicle, and switching between a first driving mode for driving the motor while using a continuous rated torque as an upper limit and a second driving mode for driving the motor while using a maximum rated torque as an upper limit, the continuous rated torque being lower than the maximum rated torque generatable by the motor. The motor controller drives the motor in the first driving mode in a case where a driver does not specify a driving mode.
