Rollover suppression control apparatus and rollover suppression control method

A rollover suppression control apparatus comprising:

• a rollover state value detection unit which detects a rollover state value indicating that a vehicle is under rollover tendency;
• a comparison unit which compares the detected rollover state value with a control threshold value;
• a braking force applying unit which performs a rollover suppression control of applying braking force to a wheel of the vehicle to suppress the rollover of the vehicle when the detected rollover state value is greater than the control threshold value;
• a understeer state detection unit which detects whether a traveling state of the vehicle is a understeer state or a non-understeer state;
• and
• a control threshold value setting unit which sets a first control threshold value as the control threshold value when the traveling state is detected as the non-understeer state, and which sets a second control threshold value greater than the first control threshold value as the control threshold value when the traveling state is detected as the understeer state.
