摘要： A drive force control method for a four-wheel drive vehicle including a torque distributing mechanism capable of changing a drive force distribution ratio between front and rear wheels and a drive force distribution ratio between right and left front wheels or between right and left rear wheels. This method includes the steps of increasing the drive force distribution ratio of the rear wheels to the front wheels according to an increase in absolute value of a lateral G signal, and increasing the drive force distribution ratio of a turning outer wheel as one of the right and left front wheels or one of the right and left rear wheels to a turning inner wheel as the other. A lateral G sensor signal is corrected by an estimated lateral G signal calculated according to a steering angle and a vehicle speed to obtain a control lateral G signal, which is used as the lateral G signal.

摘要： Provided are a method and system for computing a vehicle body slip angle in the vehicle movement control so as to allow the vehicle movement to be controlled with an adequate response and stability for practical purposes even without directly detecting or accurately estimating the frictional coefficient between the road surface and the tire. A tire slip angle is computed from a yaw rate, a vehicle speed, a vehicle body slip angle and a road wheel steering angle; a cornering force is computed from a dynamic model of the tire by taking into account at least the tire slip angle; and a hypothetical vehicle body slip angle is computed from the cornering force, the vehicle speed and the yaw rate; the tire slip angle being computed by feeding back the hypothetical vehicle body slip angle in a recursive manner.

摘要： A suspension system for the steered wheels of a vehicle include knuckles, the lower portions of which are pivotally supported at tip ends of a lower arm and a radius rod through two ball joints. Each of the steered wheels is steered about a phantom king pin axis passing through an intersection a of extensions of the lower arm and the radius rod so that, during clockwise turning of the vehicle, the point a of an outer wheel during turning of the vehicle is little moved, but the point a of an inner wheel during turning of the vehicle is moved inwards of a vehicle body through a distance .alpha..sub.R whereby a distance between a ground point of the inner wheel and the phantom king pin axis is larger than a distance between a ground point of the outer wheel and the phantom king pin axis and, hence, left and right steering moments generated by driving forces of the left and right steered wheels are countervailed with each other, whereby the generation of unnecessary steering moments is prevented as a whole.

摘要： A driving force distributing device is provided for distributing a driving force of an engine to the left and right wheels of a vehicle by bringing a pair of hydraulic clutches into and out of their engaged states. The distributing device includes a hydraulic pump mounted within a casing thereof and driven through gears by a half shaft connected to one of the wheels. An oil passage interconnects the hydraulic pump and the hydraulic clutches, the oil passage being defined in a casing. A valve block is coupled to an upper surface of the casing. Thus, the oil passages interconnecting the hydraulic pump and the hydraulic clutches of the driving force distributing device can be compactly formed.

摘要： A torque distributing mechanism includes a first and a second planetary gear mechanism. Among pairs of planetary carriers, ring gears and sun gears in these planetary gear mechanisms, one of the pairs are coupled to two output elements of a differential; another pair are relatively non-rotatably connected to each other, and one of the components of the remaining pair is fixed, while the other is connected to a driving source. Thus, it is possible to reduce the diametrical dimension and weight of the torque distributing mechanism and to improve the degree of freedom in design.

摘要： A wheeled vehicle is equipped with a feedforward steering control system which steers the vehicle through front or rear road wheels in accordance with a driver's steering input such as an angular displacement of a steering wheel, and a negative feedback system which senses a turning behavior of the vehicle such as a yaw rate or a lateral acceleration, and steers the vehicle through the front or rear wheels in such a negative direction as to reduce the turning behavior. The feedforward system may control the angular direction of the front or rear wheels in accordance with a linear combination of the steering input and the time derivative of the steering input, or may control the angular directions of both of the front and rear wheels in accordance with different transfer functions between the steering input and the front and rear wheel angles. The negative feedback system is combined with the feedforward system in various ways to provide desired characteristics of the turning behavior. The negative feedback quantity determined by the negative feedback system may be proportional to the sensed turning behavior, or may be determined in accordance with the difference between the sensed turning behavior, and the reference turning behavior calculated from the vehicle speed and steering input.

摘要： A vehicle is equipped with a rear wheel control device including hydraulic actuators for controllably turning rear wheels under influence of hydraulic fluid supplied thereto from a hydraulic pump. Turning the rear wheels is made in one of first and second directions which are opposite to each other, in response to steering effort applied to a steering wheel. The change-over operation of the rear wheel turning between the first and second directions takes place upon substantially stopping supply of the hydraulic fluid to the actuators, thereby preventing shock during the turning direction change-over operation.
