摘要： A target sideslip angle computing unit calculates a target sideslip angle used when a vehicle makes a turn, based on a steering angle and a vehicle speed. A target sideslip angle correcting unit corrects the target sideslip angle calculated by the target sideslip angle computing unit using a sideslip angle correction amount calculated based on at least one of a steering angular velocity, a depression amount of an accelerator pedal, a depression velocity of the accelerator pedal and a depression amount of a brake pedal. Vehicle attitude control is executed using the target sideslip angle corrected by the target sideslip angle correcting unit.

摘要： A steering system includes: an operation mechanism that includes an operation member; and a steered mechanism that is not mechanically coupled to the operation mechanism and that steers a wheel on the basis of a steering operation of the operation member. The operation mechanism includes a steering angle sensor that detects a steering angle of the operation member and a steering direction detection unit that detects a steering direction of the operation member. The steering direction detection unit includes a threaded shaft that is rotatable in the steering direction of the operation member, a nut that is screwed to the threaded shaft, a nut guide that causes the nut to move in an axial direction of the threaded shaft in accordance with rotation of the threaded shaft, and a force detection sensor that detects a force that the nut guide receives from the nut.

摘要： An apparatus for controlling a four-wheel drive vehicle includes a tire friction circle calculator that calculates the size of a tire friction circle of each wheel on the basis of vehicle information including a tire vertical load, a resultant force calculator that calculates the magnitude of a resultant force of tire lateral and longitudinal forces for each wheel, a tire-friction-force usage rate calculator that calculates a tire-friction-force usage rate of each wheel that is the ratio of the magnitude of the resultant force to the size of the tire friction circle, and a driving-braking force adjustment controller that adjusts driving force or braking force applied to each wheel. When the tire-friction-force usage rate of any wheel exceeds a predetermined threshold of less than one, the driving-braking force adjustment controller restrains an increase in the driving force or the braking force of the wheel while increasing the driving force or the braking force of at least one of the other wheels that is selected on the basis of driving operation information indicative of the state of a driving operation by a driver.
