Abstract: PROBLEM TO BE SOLVED: To control a rolling state of a vehicle optimally irrespective of the travel state of the vehicle by controlling the braking force of each wheel so as to bring the rolling angle at a target rolling angle. SOLUTION: When rolling behavior control is required over a vehicle, a target rolling angle θrt of the vehicle is set depending on the rolling direction of the vehicle (S20 to 40). Target yaw moment Nt1 for feedforward control and target yaw moment Nt2 for feedback control used to bring a rolling angle θr at the target rolling angle θrt are computed (S50 and 60). Final target yaw moment Nt is calculated as the sum of the target yaw moments (S70). Target deceleration Gxt of the vehicle is computed corresponding to the final target yaw moment Nt (S80). Controlling a braking pressure Pbi of each wheel on the basis of the target deceleration Gxt applies yaw moment corresponding to the final target yaw moment Nt to the vehicle (S100).

Abstract: PROBLEM TO BE SOLVED: To reduce the memory capacity of a memory means, and to reduce the time required for recording information data in the memory means. SOLUTION: When the magnitude of a lateral acceleration Gy of a vehicle is large (S10), a steering angle θ, a movement control quantity and the lateral acceleration Gy of several tens cycles of movement control are recorded by superscribing on a recording area together with a identification number 1 for showing to be a record of running data based on determination of the lateral acceleration Gy (S100-130).

Abstract: PURPOSE: To improve reliability in an emergency without narrowing the movable range of an oscillation table to be used in ordinary control. CONSTITUTION: An upper base plate 52 constituting the oscillation table on which a vehicle model is installed and a lower base plate 58 as a foundation base are parted from the base plate at a prescribed distance. The respective top ends of six pieces of hydraulic cylinders 36 are mounted on the rear surface of this base plate 52 and the bottom ends of the respective hydraulic cylinders 36 are mounted on the front surface of the base plate 58 in a manner as to form a triangular shape peaking at the respective mounting positions. Holders 86, 92 holding the outer peripheries of poles 82, 86 mounted respectively at the bottom ends and top ends of a freely expandable and retractable cylinder 80 are mounted on the base plate 58 and base plate 52. The inclination angle of the cylinder 80 with the base plate 58 and the inclination angle of the cylinder 80 with the base plate 52 are limited respectively to prescribed angles or below by these holders 86, 92.

Abstract: PURPOSE:To provide a power steering device to increase the steering resistance in a case quick steerings are repeated frequently more than in a case no such a quick steering is repeated, so as to prevent an excessive steering by a driver when quick steerings are repeated frequently. CONSTITUTION:A severity coefficient alpha to show the severity level of variation of the steering angle deltasw from a steering angular verocity omegasw of a steering wheel in a standard time is decided (S2 and S4). When the severity coefficient alphais less than a threshold value alphath (S5 decides as YES), a normal true solenoid current I is output (S6 to S8) to generate a normal steering resistance. On the other hand, when the severity coefficient alpha is more than the threshold value alphath, (S5 decides as NO), a true solenoid current I smaller than a normal value is output (S9, S7, and S8), so as to generate a steering resistance larger than a normal value, and thereby, an excessive steering by a driver is suppressed.

Abstract: PURPOSE:To enable the simple disconnection of an automatic steering control system at the time of switching from automatic steering to manual operation by interposing a detent mechanism between an automatic steering drive mechanism and an input shaft for a power steering mechanism. CONSTITUTION:When a driver rotates a handwheel 14 during automatic steering, rotation of a steering shaft 13b is transmitted to each fo pins 18i1, 18i2, but since a piston sleeve 31 is stopped, these pins 18i1, 18i2 are pressed to the side wall of a recess 31a and shifted toward the center of a turning shaft, whereby a contact area between a wall of the recess 31a and these pins 18i1, 18i2 is gradually reducing. When each tip of these pins 18i1, 18i2 is reached to an interval between recesses 31a, the piston sleeve 31 is shifted downward by a spring 34. With this constritution, even if the piston sleeve 31 is rotated by an automatic steering control part 24, its rotation is not transmitted to an input shaft for a control valve 18.

Abstract: PURPOSE:To prevent a burden of steering operation by a driver from increasing by releasing the connection between an automatic steering drive mechanism and an input shaft through a safety mechanism at a time when something goes wrong with an automatic steering control system and thereby such a reaction as more than the specified one has occurred in an interval between the automatic steering drive mechanism and the input shaft of a power steering mechanism. CONSTITUTION:When something goes wrong with an automatic steering control part, a servomotor 30 fails to generate driving force utterly and thereby it has become free of rotation, this trouble is inferred and if a handwheel is rotated for operation, an upper steering shaft 13b is rotated as well, and this rotation is transmitted to the upper end of an inner spool 18g via pins 18i1, 18i2. With this, a hydraulic mechanism works likewise in the case where a sleeve 31 is rotated by the servomotor 30, thus steerage by a driver is being assisted. On the other hand, when the servomotor 30 is subjected to seizure or binding at time of trouble, if a handwheel 14 is rotated for operation, some reaction occurs in space between the upper steering shaft 13b and the sleeve 31, and these pins 18i1, 18i2 separate from recess parts 31a1, 31a2, whereby the driver is released from the seizure of the servomotor 30, thereby enabling him to handle a steering wheel.

Abstract: PURPOSE:To prevent deterioration in accuracy of updating a zero estimated value so as to contrive the high speed of updating the zero estimated value by using an update limit steering angle updating the zero estimated value used outputting vehicle condition quantity information, when a steering gain is increased following changing a car speed. CONSTITUTION:A vehicle condition observing device 30 uses an update limit steering angle delta0 set by an update limit setting means 38 updating a zero estimated value and outputting vehicle condition quantity information with an updated zero estimated value a0 serving as the reference. The update limit steering angle delta0, being a function of a car speed V, is set by reading it by a car speed detecting means 40 and referred to a map. The update limit steering angle delta0(V) stored in the inside of a means 42 is a value predetermined in accordance with a steering gain of a vehicle condition quantity detecting means 32, and by using this update limit steering angle delta0(V) determining a range of a steering angle deltaSW worthy of updating, even when the steering gain is increased, the zero estimated value can be updated without deteriorating accuracy.

Abstract: PURPOSE:To improve short turning performance of a vehicle and to ensure stable turning performance by a method wherein only when the steering angle of front wheels exceeds a given value, steering is controlled so that the steering angle of rear wheels is increased in an opposite phase proportionally to that of the front wheels. CONSTITUTION:When a rear wheel steering cancel switch 52 is, for example, turned OFF, since a solenoid switching valve 51 is in a first state, working oil is fed through a flow dividing valve 23 to a spool valve 42 with the aid of a hydraulic pump 22, and left and right rear wheels RW1 and RW2 are steered in linkage with steering of left and right front wheels FW1 and FW2. When a steering handle 14 is rotated, for example, rightward, left and right front wheels FW1 and FW2 are steered rightward through a rack bar 11, a cable 68 is pulled, and left and right rear wheels RW1 and RW2 are steered leftward through a relay rod 31. In this case, when a front wheel steering angle, for example, exceeds a given value, rear wheels are controlled in an opposite phase proportionally to front wheels.
