摘要： An electronic control unit (26) determines that a vehicle is traveling in a straight line if a state in which the steering torque (T) is less than a predetermined steering torque (To) and an amount of change (Δθ) in the steering angle (θ) is less than a predetermined steering angle (θo) continues for a predetermined period of time (to) when the vehicle speed (V) is greater than a predetermined vehicle speed (Vo). Also, if the steering angle (θ) of the steering wheel (11) is not 0, while the vehicle is traveling in a straight line, the electronic control unit (26) calculates the steering amount (S) of rear wheels (RW1, RW2) that matches the steering amount of front wheels (FW1, FW2), using the steering angle (θ) of the steering wheel (11). Then the electronic control unit (26) steers the rear wheels (RW1, RW2) by driving an electric motor (14) until a controlled neutral steering position of the rear wheels (RW1, RW2) that corresponds to the steering amount (S) matches an absolute neutral steering position.

摘要： The invention relates to a device and to a method for distributing a yaw disturbance to be rejected acting on a vehicle, between a four-wheel steering system and a controlled braking system with which said vehicle is equipped, said method involving the following steps: - estimating said yaw disturbance to be rejected as a function of data relating to said vehicle; - determining a range of angles that apply to said four-wheel steering system as a function of a used four-wheel steering angle (111) and of a limit four-wheel steering angle (121); - as a function of said range of angles and of a disturbance rejection gain of said four-wheel steering system, determining a minimum yaw moment and a maximum yaw moment that can be generated by said four-wheel steering system; and - as a function of said minimum and maximum yaw moments and of said estimate of the disturbance to be rejected, distributing said estimated disturbance between said four-wheel steering system and said controlled braking system.

摘要： The invention relates to a system for controlling the turn of a pair of steering wheels (22, 24) of an automobile (10) in a braking situation with asymmetrical adhesion, said system including a means (44) for controlling the turning angle of the pair of steering wheels (22, 24) in order to minimise the difference between the braking torques applied on the right (12) and left (14) wheels of the vehicle. According to the invention, the control means (44) is capable of implementing a control rule with a dynamic variable.

摘要： A forklift truck comprises two driven front wheels 12L, 12R and a single driven central rear wheel 14. The truck is operable in a sideways mode (Figures 2A-2C) in which the rear wheel is fixed at an angle substantially- parallel to an axis passing through the two front wheels and the two front wheels are steered in synchronism in opposite directions of rotation. The truck is further operable in a rotational mode in which the centre of rotation C of the truck is disposed inside a notional circle 200 passing through all three wheels. The truck enters the rotational mode from the sideways mode by automatic reversal of the drive direction of the rear wheel, by actuating a changeover valve 40, when the centre of rotation moves from outside to inside the notional circle.

摘要： Die Erfindung betrifft ein Kraftfahrzeug mit zusätzlich zu den Vorderrädern aktiv lenkbaren Hinterrädern, deren Radaufhängung ein passiv untersteuerndes Eigenlenkverhalten hervorruft und die in Abhängigkeit vom aktuellen Fahrerwunsch und aktuellen dynamischen Betriebsparametern des Fahrzeugs eingeschlagen werden, wobei die Hinterräder im Grenzbereich des progressiven Untersteuerns aktiv derart gelenkt werden, dass deren Lenkeinschlag bei Gleichsinnigkeit mit demjenigen der Vorderräder geringer als der durch das Eigenlenkverhalten hervorgerufene wird oder sogar demjenigen der Vorderräder entgegengerichtet wird. Alternativ oder zusätzlich können die Hinterrädern auch dann solchermaßen aktiv gelenkt werden, wenn der Fahrer das Fahrzeug bei Kurvenfahrt beschleunigt. Bevorzugt wird der Übergang von einem mit den gelenkten Vorderrädern gleichsinnigen Radeinschlag der Hinterräder zu einem dem Eigenlenkverhalten entgegengerichteten Lenken im Grenzbereich des progressiven Untersteuerns dann durchgeführt, wenn die Differenz zwischen dem aus dem Fahrerwunsch abgeleiteten und dem tatsächlichen Fahrdynamik-Verhalten des Fahrzeugs einen Schwellwert überschreitet. Das Kraftfahrzeug kann mit einer Gierratenregelung und mit einer Lenkfunktion für die Vorderräder ausgerüstet sein, die dem Fahrerwunsch einen das Fahrdynamik-Verhalten des Fahrzeugs stabilisierenden Lenkwinkel überlagert.

摘要： Method of eliminating a yaw disturbance (6) in a vehicle equipped with a managed braking system, said method comprising the following steps: estimating said yaw disturbance (6) in said vehicle as a function of a plurality of parameters, said plurality of parameters comprising a speed (3) of said vehicle, a yaw speed (1) of said vehicle, an angle of the front wheels (2) of said vehicle, an angle of the rear wheels of said vehicle, a maximum lateral acceleration (4) of said vehicle, and a yaw moment (5) caused by braking; and asymptotic elimination of said estimated disturbance (6) as a function of said speed (3) of said vehicle, said elimination consisting in making said estimated disturbance (6) inobservable with respect to the yaw speed (1) of said vehicle.
