摘要： Disclosed is a vehicle operation device capable of reducing a sense of discomfort imposed on a driver when the driver carries out a driving operation and suppressing a vehicle behavior not intended by the driver. A vehicle operation ECU determines control amounts of a throttle actuator and a brake actuator in accordance with operation amounts of an accelerator pedal and a brake pedal. When a steering is being operated, a dead zone for a control amount according to an operation of a pedal is adjusted. For example, when the steering is turned to the left, the dead zone of the accelerator pedal disposed on the right side, that is, on a turning outer wheel side of the vehicle is increased.

摘要： A tire wheel structure that avoids the adverse effect of the increase in the unsprung mass associated with the presence of a driving motor at the time of a road surface input to a tire wheel is provided. In the tire wheel structure, the driving motor is disposed near the tire wheel that is supported on a vehicle body. The driving motor drives the tire wheel by transferring driving force to the tire wheel. The output shaft of the driving motor is connected to a wheel of the tire wheel via a flexible coupling. The driving motor is supported by a knuckle member of a suspension via coil springs and absorbers so that the driving motor is relatively displaceable with respect to the tire wheel.

摘要： An unsprung state detection part (140) calculates a variation amount X (=|φ−φ′|), which is a magnitude of a difference between a detected angle φ output from a resolver rotational angle sensor (40) for detecting a rotational angle of an in-wheel motor (30) and an estimated angle φ′ of a motor rotational angle (S11 to S13). The estimated angle φ′ can be calculated by adding an estimated angle of the rotation of the motor (30) in one calculation cycle to a detected angle φn−1 of the previous calculation cycle. When the variation amount X is more than a road surface determination threshold Xref, the unsprung state detection part (140) determines that the travel road on which a vehicle (1) is traveling is a rough road (S14, S15). As a result, the road surface determination can be made by using the rotational angle sensor (40).

摘要： A braking force control apparatus for a vehicle estimates the friction coefficient μ of a road surface as the state of the road surface on which the vehicle travels, and determines an ideal braking force μW by making use of the estimated road surface friction coefficient μ. When μ is equal to or greater than a predetermined friction coefficient μ0, the braking force control apparatus operates an in-wheel motor in a regeneration state to generate a motor braking torque Tmr, and causes a friction brake mechanism to generate a frictional braking force Bf computed by subtracting Tmr from μW. When μ is less than μ0, the braking force control apparatus operates the in-wheel motor in a power running state to generate a motor driving torque Tmc, and causes the friction brake mechanism to generate a Bf computed by adding Tmc to μW.
