VEHICLE ROLLOVER PREVENTION CONTROL APPARATUS AND VEHICLE ROLLOVER PREVENTION CONTROL METHOD
First Claim
1. A vehicle rollover prevention control apparatus comprising:
- an actuator configured to control a dynamic behavior of a vehicle;
a rollover prediction section configured to make a rollover prediction, based on a driver-applied steering input, whether a predetermined level of roll motion for the vehicle occurs;
a steering-back detection section configured to detect a driver-applied steering-back action;
a rollover decision section configured to make a rollover decision about rollover of the vehicle when the driver-applied steering-back action has been detected; and
a rollover prevention control section configured to execute rollover prevention control by controlling the actuator, when it is predicted for the predetermined level of roll motion to occur by the rollover prediction section and the rollover decision that rollover will occur has been made by the rollover decision section.

Abstract
In a vehicle rollover prevention control apparatus employing a brake system serving as an actuator configured to control a dynamic behavior of a vehicle, a steering-input decision section is provided to make a rollover prediction, based on a driver-applied steering input, whether a predetermined level of roll motion for the vehicle occurs, and also to detect a driver-applied steering-back action. Also provided is an active rollover prevention control intervention decision section configured to make a rollover decision about rollover of the vehicle when the driver-applied steering-back action has been detected. An active rollover prevention control section is configured to execute rollover prevention control by controlling the actuator, when it is predicted for the predetermined level of roll motion to occur by the steering-input decision section and the rollover decision that rollover will occur has been made by the active rollover prevention control section.

9. A vehicle rollover prevention control apparatus comprising:
-
an actuator configured to control a dynamic behavior of a vehicle; a steering angular velocity detection section configured to detect a steering angular velocity during a driver-applied further steering action; a steering angle sensor configured to detect a steering angle; a yaw rate sensor configured to detect a yaw rate of the vehicle; an acceleration sensor configured to detect a lateral acceleration exerted on the vehicle; a rollover prediction section configured to make a prediction, based on at least a signal from the steering angular velocity detection section and a signal from the steering angle sensor, whether a predetermined level of roll motion for the vehicle occurs; a vehicle behavior detection section configured to detect the vehicle dynamic behavior based on information from at least the yaw rate sensor and the acceleration sensor; a rollover decision section configured to make a rollover decision about rollover of the vehicle when a driver-applied steering-back action has been detected for a period of time during which the vehicle behavior detection section determines that a specified vehicle behavior occurs; and a rollover prevention control section configured to execute rollover prevention control by controlling the actuator, when the rollover decision that rollover will occur has been made by the rollover decision section. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A vehicle rollover prevention control method comprising:
-
executing a rollover prediction, based on a steering angular velocity of a vehicle during a driver-applied further steering action, whether a high level of roll motion for the vehicle occurs; and executing rollover prevention control when a driver-applied steering-back action has been detected after the rollover prediction has been satisfied. - View Dependent Claims (18, 19, 20)
