摘要： A suspension ECU (13) calculates a target characteristic variable coefficient (a_new) for changing target characteristics expressed in a quadratic function, by using both the maximum real roll angle (Φ_max) having occurred in a car body in a present turning state and such a turning pitch angle (Θ_fy_max) of a real pitch angle (Θ) as to occur according to a turning motion, and changes the target characteristics by using the coefficient (a_new). On the basis of the changed target characteristics, moreover, the suspension ECU (13) calculates a difference value (ΔΘ) between a target pitch angle (Θh) corresponding to a real roll angle (Φ) and the real pitch angle (Θ), and calculates a demanded total damping force (F) which has to be so generated by the coaction of a shock absorber as to reduce the value (ΔΘ) to 'zero'. In proportion to the magnitude of a lateral acceleration (Gl), moreover, the suspension ECU (13) distributes the demanded total damping force (F) into a demanded damping force (Fi) on the turning inner side and a demanded damping force (Fo) on the turning outer side.

摘要： A damping force control apparatus for a vehicle computes an actual roll angle Φ and an actual pitch angle ϑ in step S11, and computes a difference Δϑ between a target pitch angle ϑa and the actual pitch angle ϑ in step S12. In step 13, the apparatus computes a total demanded damping force F which must be cooperatively generated by shock absorbers so as to decrease the computed Δϑ to zero. In step S14, the apparatus distributes the total demanded damping force F in proportion to the magnitude of a lateral acceleration G such that a demanded damping force Fi on the turn-locus inner side becomes greater than a demanded damping force Fo on the turn-locus outer side. In step S15, the apparatus controls the damping force of each of the shock absorbers to the damping force Fi or the damping force Fo. Thus, throughout a turn, a posture changing behavior in which the turn-locus inner side serves as a fulcrum can be maintained.

摘要： A suspension ECU 13 calculates a target characteristic changing coefficient a_new for changing a target characteristic, which is represented by a quadratic function, by use of the maximum actual roll angle Φ_max generated in a vehicle body during the current turning state and a turning pitch angle Θ_fy_max which is a fraction of an actual pitch angle Θ generated as a result of turning, and changes the target characteristic by use of the coefficient a_new. Subsequently, the suspension ECU 13 calculates the difference ΔΘ between the actual pitch angle Θ and a target pitch angle Θh corresponding to the actual roll angle Φ on the basis of the changed target characteristic, and calculates a total demanded damping force F to be cooperatively generated by the shock absorbers so as to reduce the difference ΔΘ to zero. Furthermore, in proportion to the magnitude of a lateral acceleration Gl, the suspension ECU 13 distributes the total demanded damping force F into a demanded damping force Fi on the turning-locus inner side and a demanded damping force Fo on the turning-locus outer side.

摘要： In a steering apparatus, in accordance with a grip limit control process (30b'), it is determined whether or not a grip degree ε estimated by a grip degree estimation arithmetically operating process (30a) is less than a predetermined grip degree ( ε'), and in the case that it is determined that an estimated grip degree (ε) is less than the predetermined grip degree (ε'), the process applies such a feeling that a steering operation by a steering wheel suddenly becomes light to a driver, by suddenly increasing an assist quantity by a motor (M) , thereby notifying the driver of the matter that the grip degree of a steered wheel is close to a limit. Therefore, it is possible to transmit to the driver a probability that a side slip is generated by further turning the steering wheel 21 in the same direction as the current direction, thereby calling the driver's attention for steering. Accordingly, there is an effect that a stability of a vehicle behavior can be improved without applying any fear of insecurity to the driver.

摘要： A steering device, wherein a grip limit control processing (30b') judges whether or not a grip level ɛ estimated by grip level estimation processing (30a) is less than a specified grip level ɛ', and if judged to be less than ɛ', an assist power by the motor (M) is quickly increased to thereby let a driver feel a suddenly lightened steering by a steering wheel and inform the driver that the grip level of the steering wheel is nearing its limit. Accordingly, the probability of skidding to be caused by turning the steering wheel further in the same direction is informed to the driver to call a steering attention to the driver. Therefore, the stability of vehicle behavior can be enhanced without getting the driver feel uneasiness.
