摘要： PURPOSE:To rapidly calculate the lateral acceleration of a vehicle by performing predetermined operation on the basis of the first lateral acceleration calculated from steering power and the second lateral acceleration calculated from a car speed and a steering angle. CONSTITUTION:A steering power detection means 2 for detecting steering power, a car speed detection means 3 for detecting a car speed and a sterring angle detection means 4 for detecting a steering angle are provided and, further, the first lateral acceleration calculation means 5 for calculating the first lateral acceleration from the steering power and the second lateral acceleration calculation means 6 for calculating the second lateral acceleration from the car speed and the steering angle are provided. Then, the first lateral acceleration calculated by the means 5 to which the function of the steering power and lateral acceleration in the high friction coefficient (mu) of a road surface is preset and the second lateral acceleration calculated by the means 6 to which the function of the steering angle and lateral acceleration are preset in the same way are subjected to predetermined operation so as to set off the error of the heteropolarity with real lateral acceleration by the lateral acceleration calculation means 7 of a vehicle. By this method, the real lateral acceleration of the vehicle can be always calculated without receiving the effect of the friction coefficient (mu) of the road surface.

摘要： PURPOSE:To control pressures to a number of fluid machines with a single valve body by disposing a variable throttle which changes its opening according to the displacement of a valve body between a fluid inlet and an outlet for the control pressure, and a back pressure generating throttle between the outlet and a fluid discharge port, and urge-driving the valve body by means of controller. CONSTITUTION:One of solenoids 31L and 31R is energized with a current from a controller 27 commensurate with the steering angle, steering force, etc. of a steering wheel, and urges a valve body 30 of a pressure control valve 26 with an urging force in proportion to the energizing current. The valve body 30 displaces according to the urging force. Variable throttles 32L and 32R changes their openings according to the displacement of the valve body 30 to change the flow rate of fluid through back pressure generating throttles 37L and 37R. Pressures commensurate with the flow rates are outputted as control pressures from outlets 36L and 36R. Thus the control pressure can be determined with the displacement of a single valve body to accurately perform proportional control, etc.

摘要： PURPOSE:To easily perform the pressure rise, decompression and anti-roll of respective fluid chambers by respectively arranging orifices for generating damping force and one-way valves in parallel on respective supply/drainage passages which connect one control valve to respective upper and lower fluid chambers in plural cylinders. CONSTITUTION:Respective snubbers D1-D4 have pistons 6 which partitions respective cylinders 1 into upper and lower fluid chambers 2, 4. Respective fluid chambers 2, 4 are connected to a fluid pressure source through respective supply/drainage passages 8, 9 which have a control valve 21 on the way. In this case, on respective supply/drainage passages 8, 9, plural orifices 11, 14 for generating damping force and one-way valves 12, 15 which open when working fluid flows from the fluid pressure source into respective fluid chambers 2, 4 are arranged in parallel. With this arrangement, one of fluid chambers 2, 4 is decompressed and the pressure of the other is raised by the control valve 21. In addition, the control valve 21 is changed over by the fluid pressure of a power steering device so as to function as a suspension device for anti-roll.

摘要： PURPOSE:To improve the kinetic performance of a vehicle by providing a torque transmission gear which transmits power to right and left wheels without transiting a differential gear, a torque transmission clutch which makes the amount of transmission torque variable, and a controller which controls the amount of torque transmission according to the kinetic situation of the vehicle. CONSTITUTION:When a load is applied to the hydraulic multiple disk clutch 25 (torque transmission clutch) by a controller during the turning run of a vehicle in the low to middle speed range, for example, the clutch is brought into the engagement state so that the rotation of an intermediate shaft 15 is transmitted to a right wheel output shaft 7 via gears 18 and 14. At this time, since the relation between both the numbers N1 and N2 of the teeth of the acceleration gears 12 and 16 which transmit the rotation from a power transmission shaft 8 to the intermediate shaft 15 and the numbers N3 of the teeth of the deceleration gears 18 and 14 which transmits the rotation from the intermediate shaft 15 to the output shafts 6 and 7 is N4/N3>N1/N2, the revolution speed of the left wheel output shaft 6 turning together with a differential case 2 becomes higher than that of the right wheel output shaft 7. Accordingly, the turning performance in the low to middle speed range may be improved.

摘要： PROBLEM TO BE SOLVED: To simply realize the steering stability compatible with initial turnability by controlling the steering angle so as to be an opposite phase at the initial time of the steering and so as to be the same phase at the intermediate time of the turning and so as to be neutral in the steady turning condition. SOLUTION: Rise of a yaw rate is delayed in relation to rise of the steering angle speed of a steering wheel 9 at the initial time of turning. An absolute value of a dδh/dt is larger than an absolute value of dγ/dt. Since a rear wheel target steering angle has a negative value, rear wheels 7R, 7L are steered to the opposite phase in relation to front wheels 8R, 8L. At the intermediate time of turning, an absolute value of the steering angle of the steering wheel 9 is smaller than an absolute value of the yaw angle acceleration. The rear wheel target steering angle δr becomes a positive value, and the rear wheels 7R, 7L are steered to the same phase in relation to the front wheels 8R, 8L. In steady turning condition, both of the steering angle δh and the yaw rate γdo not change. Both of the steering angle speed dδh/dt and the yaw angle acceleration dγ/dt become zero, and the rear wheel target steering angle δr becomes zero.

摘要： PROBLEM TO BE SOLVED: To dissolve a lowering of steering wheel stability when a steering angle is large by generating self-alighting torque for restoring a steering wheel into a neutral position in a control means for controlling the operation of a motor-driven power steering for applying steering assist torque to a parallel geometry type steering system. SOLUTION: A target current setting means M1 of an electronic control unit U computes a target current IMS for driving a motor 27 of a motor-driven power steering S on the basis of steering torque T detected by a steering torque detecting means S1, a steering angle θ detected by a steering angle detecting means S2, vehicle speed V detected by a vehicle speed detecting means S3 and steering rotating speed N computed by a steering rotating speed computing means M2. A driving control means M3 converts the target current IMS into motor control voltage V0 and drives the motor 27 through a motor driver 32. At this time, a lowering of steering wheel stability is compensated by generating larger steering assist torque to the motor-driven power steering S in proportion to the increase of the steering angle and the decrease in the vehicle speed.

摘要： PROBLEM TO BE SOLVED: To increase driving force by preventing idle rotation in a turning inner side rear wheel at turning time by setting suspension geometry so as to become large to the toe-in side by generating a difference not less than a specific degree between a toe angle and a toe angle at maximum bump time by the toe angle at maximum rebound time caused by turning. SOLUTION: A difference between a toe angle (a) at maximum rebound time of a rear suspension at vehicle turning time and a toe angle (b) at maximum bump time of the rear suspension at vehicle turning time is determined. Suspension geometry of the rear suspension is set so that the difference (a-b) becomes large. Particularly, the suspension geometry is set so that a value by subtracting the toe angle (b) at maximum bump time from the toe angle (a) at maximum rebound time becomes 0.5 degree or more. Thus, a wheel speed of a turning inner ring becomes a value closer to a wheel speed of a turning outer ring to restrain the occurrence of idle rotation in a turning inner side driving wheel to the possible minimum level to increase driving force.
