    摘要: A road surface friction coefficient μ is calculated based on a detected lateral acceleration and a front-rear acceleration, and a roll angle is calculated using a roll rate. Further, a maximum engine torque value that can be applied to a drive wheel without causing slipping thereof is calculated based on the road surface friction coefficient μ and a gear ratio. A torque transmission rate that indicates a reduction rate for engine output is set so as to reduce in accordance with a roll angle, and a target engine torque value is calculated by correcting the maximum engine torque value using the torque transmission rate. Accordingly, adjustment is executed such that the engine output is made smaller as the roll angle increases. Thus, abrupt changes in vehicle behavior are not caused by sudden starting of control, and it is possible to inhibit drive feeling from deteriorating.

    摘要: A system and method for providing a vehicle roll stability indicator that dynamically estimates the probability for vehicle rollover. The system determines vehicle kinematics from various vehicle sensors. From these kinematic values, the system estimates a roll angle of the vehicle and a bank angle of the vehicle. The estimated bank angle is used to correct the roll angle. The system determines a roll energy of the vehicle and a roll energy rate of the vehicle from the corrected roll angle. The system also calculates a tire lateral load transfer of the relative forces on the vehicle tires, and the duration that any of the tires have been off of the ground. From the roll energy, the roll energy rate, the tire lateral load transfer and the wheel airborne duration, the system calculates the roll stability indicator.

    摘要: A roll-over suppressing control apparatus for a vehicle is disclosed which can carry out roll-over suppressing control appropriately in response to the type of turning. Upon turning of the vehicle, if a parameter corresponding to the rolling behavior of the vehicle becomes higher than a control start criterion value set in advance, then roll-over suppressing control of suppressing rolling of the vehicle is started. Then, if the parameter becomes lower than a control end criterion value set in advance, then the roll-over suppressing control is ended. As the control end criterion value, a steady turning control end criterion value is used when the turning of the vehicle is steady turning, but when the turning of the vehicle is non-steady turning such as lane change turning, a non-steady turning control end criterion value set to a value lower than that of the steady turning control end criterion value is used.
