摘要： A vehicle behavior control apparatus is divided into three major parts, sensors for detecting engine and vehicle operating conditions, a target yaw rate establishing section for establishing the rate and differential limiting apparatuses for selectively varying distribution ratios of driving force between front and rear wheels and/or between left and right wheels. The target yaw rate establishing section calculates a target yaw rate based on a vehicle mass, a mass distribution ratio between front and rear axles, front and rear axle mass, distances between front and rear axles and a center of gravity, a steering angle of a front wheel, and front and rear wheels equivalent cornering powers. A steady state yaw rate gain is separately calculated for left and right steering, respectively. A reference yaw rate is calculated by correcting a time constant of lag of yaw rate with respect to steering based on estimated road friction coefficient.

摘要： PROBLEM TO BE SOLVED: To provide a estimating device for a road surface friction coefficient capable of enhancing the presuming accuracy of the road surface friction coefficient by using an initial value of high reliability in autonomous estimation of the road surface friction coefficient. SOLUTION: The road surface μ is estimated by updating the road surface μ from time to time using the current value of the estimated road surface μ (estimated value E) as the reference. In case road surface information in the vehicle advancing direction sensed by the road side infrastructure is acquired, a specific part 11 specifies the the road surface friction coefficient on the basis of the road surface information. A estimation part 12 sets the specified road surface μ (μinf) as the initial value and starts estimating the road surface friction coefficient using this initial value as the reference upon resetting the current value of the road surface μ to the initial value.

摘要： A road surface μ is updated with time on the basis of a present value (an estimation value E) of the road surface μ estimated to estimate the road surface μ. In this case, if there is acquired road-surface information in a vehicle travel direction that is detected by a road-side infrastructure, a specifying unit 11 specifies a road-surface friction coefficient based on the road-surface information. An estimating unit 12 sets the road surface μ (μinf) thus specified as an initial value, resets the present value of the road surface μ to the initial value, and then starts estimation of the road-surface friction coefficient based on this initial value. Accordingly, estimation precision of a road-surface friction coefficient is enhanced by using an initial value having high reliability in autonomous estimation of the road-surface friction coefficient.

摘要： A system and method are provided for controlling or automatically controlling the driving dynamics of a two-track, two-axle motor vehicle having only one driven axle, which, for the rolling moment support, has a system for changing the distribution of the wheel contact forces to the left and right wheel respectively of each axle. The fractions of the rolling moment support taken over by the front axle and by the rear axle are changeable as a function of the drive torque provided by the drive assembly of the motor vehicle. For this purpose, a desired wheel contact force for the driven wheels can be determined from the drive torque, and by way of this desired wheel contact force, the distribution of the rolling torque support can be determined. A change of the distribution of the rolling moment support as a function of the drive torque of the drive assembly is preferably carried out only if the otherwise available contact force would otherwise not be sufficient for the transmission of the drive torque to the road. A slip control may be superimposed on this pilot control, which slip control seeks to minimize the deviation between the determined rotational speed difference of the driven wheels and the rotational speed difference corresponding to the respective driving condition.

摘要： A stability control system includes a sensor for measuring the position of the suspension system. Alternatively, the sensor may directly detect the load on the suspension system. With this information, the system calculates a vehicle loading condition. A yaw rate model is selected based on the calculated vehicle loading condition. Preferably, a number of loading condition values are stored and a controller selects the best fitting loading condition value to serve as the yaw rate model.
