To make it possible, in a suspension controlling apparatus for a vehicle which includes a suspension whose damping force is variably settable and a control unit capable of controlling the damping force of the suspension on the basis of a target damping force, to control the damping force of the suspension with a desired control amount and a high responsibility. [Solving Means] A control unit 28 includes acceleration calculation means 45A for calculating an acceleration in a forward and rearward direction of a vehicle on the basis of an operation input amount to the vehicle and target damping force setting means 47 for determining a target value of damping force on the basis of a damping force map determined in advance in response to the acceleration and a differentiation value of the acceleration.
摘要:
Methods and systems are described for monitoring a determined wheel speed of a wheel. A three wheel speed values—each indicative of a measured wheel speed of a different wheel—are each received from a different wheel speed sensor. An estimated wheel speed value for a fourth wheel is determined based on at least one of the three wheel speed values. A calculated wheel speed value is determined based on information received from a vehicle system. A fault condition is detected based on deviations between the estimated wheel speed value for the fourth wheel and the calculated wheel speed value for the fourth wheel.

Die Erfindung betrifft ein Verfahren und eine Einrichtung zur Steigerung des Fahrkomforts sowie zur Verkürzung der Schaltzeit beim Gangwechsel eines Stufengetriebes in einem Kraftfahrzeug, insbesondere bei einem Nutzfahrzeug mit einem Auflieger, wobei zum Zeitpunkt einer Last-Rücknahme im Zuge einer Einleitung eines Gangwechsels die Dämpfung zwischen dem Fahrzeugrahmen und der Vorderachse derart gesteuert wird, dass die Lage des Fahrzeugrahmens im wesentlichen beibehalten wird, wodurch der Fahrkomfort gesteigert wird und die Schaltzeit beim Gangwechsel verkürzt wird.
摘要:
A suspension control system for controlling a suspension having a shock absorber (M1) provided for a wheel of a vehicle includes a damping force detector (M2) which generates a damping force detection signal which indicates a change of a damping force of the shock absorber based on a condition of a road surface on which the vehicle is running. The system also includes a sprung resonance component extraction unit (M3, M3a) which extracts a sprung resonance component signal (PR, P, Psp) from the damping force detection signal. The sprung resonance component signal includes components having frequencies around a sprung resonance frequency of the shock absorber. Further, the system includes a determining part (M4, M4a, M4b, M4c) which determines whether or not the sprung resonance component signal exceeds a first level range provided for detecting a sign of the occurrence of a long-term vehicle vibration and which outputs a determination result. Moreover, the system includes a damping force controller (M4, M4a, M4b, M4c) which controls the shock absorber so that when the determining part determines that the sprung resonance component signal exceeds the first level range, the damping force of the shock absorber is altered to and maintained at an increased level and thus the suspension is maintained at a state which corresponds to the increased level and which is harder than before.

A suspension control system for controlling an suspension (S0) having a shock absorber (M1) provided for each wheel of a vehicle includes a damping force change rate detector (M2) which detects a damping force change rate (V) indicating a rate of change of a damping force of the shock absorber, and a damping force controller (M3) which alters the setting of the damping force on the basis of a relationship between the damping force change rate and an adjustment reference value (Vref). The system also includes a road surface condition detector (M4) which detects a condition of a road surface on which the vehicle is running on the basis of a change of the damping force of the shock absorber. Further, the system includes a damping force adjustment correcting unit (M5) which corrects the adjustment reference value by learning the adjustment reference value on the basis of a parameter (N) related to the damping force of the shock absorber which reflects the condition of the road surface.

摘要:
[Object] To make it possible, in a suspension controlling apparatus for a vehicle which includes a suspension whose damping force is variably settable and a control unit capable of controlling the damping force of the suspension, to appropriately obtain a pitch behavior. [Solving Means] When a vibration state of a vehicle in a vertical direction exceeds a given vibration state, a control unit 28 controls damping force of suspensions 22F and 22R on the basis of a target damping force in order to execute skyhook control, but when acceleration in a forward and rearward direction of the vehicle is outside a given range, a decision condition for the given vibration state is changed to a condition on the side on which skyhook controlling damping force control of the suspensions 22F and 22R is less likely to be started.
摘要:
To provide a new vehicle control technique, a calculation section calculates a cornering power ka using the detected longitudinal force Fx, lateral force Fy, and vertical force Fz, and the identified friction coefficient µ. This calculation is made based on the correlation between a slip angle β of the wheels and the lateral force Fy. Based on thus calculated cornering power ka and a target cornering power ka' required for the wheels, a processing section determines a change amount for changing at least one action force out of the longitudinal force Fx, the lateral force Fy, and the vertical force Fz, all acting on the wheels. Based on thus determined change amount, a control section controls at least one action force out of the longitudinal force Fx, the lateral force Fy, and the vertical force Fz, all acting on the wheels.
