摘要： A vehicle-behavior detecting apparatus including a first-yaw-moment calculating unit, a second-yaw-moment calculating unit, and an indication-value calculating unit. Based on a linear bicycle model, the first-yaw-moment calculating unit calculates a first-yaw-moment during constant-speed turning. The second-yaw-moment calculating unit reads the longitudinal acceleration detected by an acceleration sensor in addition to the parameters read in the first-yaw-moment calculating unit, and calculates a second yaw moment during acceleration or deceleration. The indication-value calculating unit calculates a variation value in the yaw moment showing the vehicle behavior from the difference between the first yaw moment during constant-speed turning and the second yaw moment during accelerated or decelerated turning. The variation in the yaw moment due to the vehicle-load shift during accelerated or decelerated turning is compensated for by the variation value.

摘要： A yaw stability control system (18) is enhanced to include roll stability control function for an automotive vehicle and includes a plurality of sensors (28–39) sensing the dynamic conditions of the vehicle. The sensors may include a speed sensor (20), a lateral acceleration sensor (32), a yaw rate sensor (28) and a longitudinal acceleration sensor (36). The controller (26) is coupled to the speed sensor (20), the lateral acceleration sensor (32), the yaw rate sensor (28) and a longitudinal acceleration sensor (36). The controller (26) generates both a yaw stability feedback control signal and a roll stability feedback control signal. The priority of achieving yaw stability control or roll stability control is determined through priority determination logic. If a potential rollover event is detected, the roll stability control will take the priority. The controller for roll stability control function determines a roll angle of the vehicle from the lateral acceleration sensor signal and calculates the feedback control signal based on the roll angle.

摘要： An active suspension system for an automotive vehicle is provided which regulates relative displacement between a vehicle body and wheels. This suspension system includes first and second gain controllers associated with hydraulic cylinders for supressing vehicular rolling based on lateral acceleration acting on the vehicle body. The first and second gain controllers amplify the level of the lateral acceleration, monitored by a sensor, by first and second gains respectively to vary pressure of the hydraulic cylinders. The suspension system further includes a low-pass filter which restricts a frequency of a signal output from the acceleration sensor high than a preselected cutoff frequency to decrease the second gain relative to the first gain to reduce the degree of load shift for the rear wheels relative to that of the front wheels.

摘要： In a hydraulic active suspension system, a plurality of actuators having working fluid chambers are provided corresponding to vehicle wheels. Each actuator is adapted to increase and decrease vehicle height as the results of the supply and the discharge of working fluid to and from its working fluid chamber, respectively. Supplying and discharging devices supply working fluid to and discharge from the working fluid chamber. Vehicle height sensors detect the vehicle heights at the locations corresponding to the vehicle wheels. A control device is further provided. The control device controls the supplying and discharging devices so that the pressure within the working fluid chamber in each actuator may be a value corresponding to the sum of a basic pressure determined according to the running conditions of the vehicle and a compensating pressure determined based upon the integral value of the difference between a standard vehicle height and an actual vehicle height. When the integral value of the difference is larger in magnitude than a predeterminate value, it is reduced in magnitude by the control device so as to prevent the control with the compensating pressure from overriding the control with the basic pressure.

摘要： An improved vehicle suspension system capable of providing at all times a desirable maneuvering characteristic variable in response to changes in the angle of steering. The suspension system includes front wheel suspension assemblies for resiliently suspending the front wheels of the vehicle and rear wheel suspension assemblies for resiliently suspending the rear wheels of the vehicle. The front wheel suspension assemblies and/or the rear wheel suspension assemblies have a variable suspension characteristic which is controlled to vary in response to a steering angle exceeding a predetermined level in a manner such that the steering characteristic of the vehicle during steering operation is changed in a direction toward an oversteer characteristic as compared with the steering characteristic during non-steering operation. Specifically, the suspension characteristic of the front wheel suspension assemblies and/or the rear wheel suspension assemblies is changed to make the ratio of the suspension rate of each front wheel suspension assembly to that of each rear wheel suspension assembly smaller during steering operation than during non-steering operation. Also, the steering characteristic of the vehicle may be further controlled such that the understeer characteristic of the vehicle is stronger at high speed than at low speed.

摘要： A method of controlling drivability of a vehicle detects an overall load acting on the vehicle. A mass of the vehicle or an estimate thereof is obtained. A controller determines whether the vehicle is negotiating a curve during a driving situation. If the vehicle is negotiating a curve during the driving situation, the controller determines whether the vehicle has a tendency to oversteer or to understeer. The load acting on the vehicle is dynamically changed or a suspension stiffness of the vehicle is dynamically adjusted to reduce the tendency of the vehicle to oversteer or to understeer.
