A method and a device for influencing the handling characteristics of a vehicle, by increasing the vehicle stability and hence increasing the driving comfort for the driver of the vehicle. This is done by activating at least two systems in the vehicle, which improve the handling characteristics and thus the vehicle stability. The activation of a system occurs in a specified sequence as a function of the activation and/or of the effect of the preceding systems on the handling characteristics achieved by the activation. The sequence provided for this purpose is the initial activation of a chassis system, followed by a steering system and finally by a brake system. |

An estimating unit 7 estimates an element aij of a system matrix based on state quantity including at least a longitudinal force Fx applied to a wheel, a vertical force Fz applied to the wheel and a vehicle speed V. A setting unit 8 sets a target value aij′ regarding the element aij of the system matrix. A processing unit 9 calculates a control value so that the estimated element aij approaches the set target value aij′. Controlling units 10 to 13 control a vehicle based on the calculated control value. Here, the element aij is expressed by a sum of a linear term changing with linearity of the wheel and a nonlinear term changing with nonlinearity of the wheel, and the setting unit 8 sets the linear term of the element aij as the target value aij′. |

The present invention is a vehicle stability system that affords safe turn with higher speed as well as maximum brake performance and resists rollover by using one or more electrical and mechanical modes to shift the center of gravity of the vehicle into a more stable position in the event of a turn condition. A preferred embodiment of the present invention utilizes an active tilt control to tilt the vehicle in the opposite direction to the vehicle's natural inclination to tilt. A second preferred embodiment utilizes a shifting weight, that is a ballast or any heavy part of the vehicle to move the center of gravity toward to side of the vehicle tending to lift up during a tilt condition. The first and second preferred embodiments can be used alone or in combination to create a more dynamic stable condition for the vehicle in turn mode. |

A yaw control system for an automotive drivetrain includes an equal torque differential, an engine-driven hydraulic pump, and hydraulically actuated control brakes operable to apply a resistive torque to either a left or right axle of the driven wheels. An acceleration-responsive control valve actuates one of the control brakes according to the direction of lateral acceleration of the vehicle. The control valve includes an inertial or seismic mass that moves a valve member to connect or disconnect the control brakes from the hydraulic pump. The control brakes are attached to the vehicle chassis so the resistive torque is reacted through the chassis, thereby inducing a yaw moment that coincides with and assists the turning of the vehicle. |

An active actuator is interposed between the unsprung mass and the sprung mass of a vehicle, and a controller selectively extends and retracts the actuator at a prescribed acceleration so as to selectively apply an additional contact load to the wheel by making use of the inertial force of the sprung mass and/or the unsprung mass of the vehicle. A particularly advantageous result can be achieved by increasing the tire contact load when the wheel is about to lock up when braking. The present invention can thus reduce the braking distance for the given road condition. |

A running state control system having running state control means for controlling a running state of a vehicle, in which a control target quantity thereof is set different according to a steering angle, comprises steering angle detecting means for detecting the steering angle, and steering angle changing means for changing the steering angle detected by the steering angle detecting means into a filtered steering angle a decrease of which lags behind a decrease of an actual steering angle. Consequently, an abrupt change in a control condition can be prevented even during a slalom run and counter steering of a vehicle, thus enhancing a running stability of the vehicle. |

A method for detecting a slope of a road on which a vehicle is traveling in at least one spatial direction. The vehicle has a body and a chassis with a plurality of wheels. An inclination of the vehicle body in the spatial direction is determined. For at least one wheel, a vertical distance to the vehicle body is detected. The distance so determined is used to calculate an inclination of the chassis in the spatial direction. The slope of the road in the spatial direction is determined from a difference between the inclination of the vehicle body in the spatial direction and the inclination of the chassis in the spatial direction. |
