Claim 2:
3. The vehicle turn-over determination apparatus according to claim 1,
wherein, in the case where the road-surface detector has detected that the road surface which is present in the traveling direction of the vehicle descends leftward, the determination processor is configured to:
calculate a first value so that the first value increases as an inclination angle of the road surface with respect to a horizontal plane increases;
calculate a second value so that the second value increases as the inclination angle of the road surface with respect to the horizontal plane increases;
decrease the absolute value of the first roll angle threshold (D1) and the absolute value of the second roll angle threshold (D2) by the first value;
decrease the absolute value of the first roll velocity threshold (V1) and the absolute value of the second roll velocity threshold (V2) by the second value;
increase the absolute value of the third roll angle threshold (D3) and the absolute value of the fourth roll angle threshold (D4) by the first value; and
increase the absolute value of the third roll velocity threshold (V3) and the absolute value of the fourth roll velocity threshold (V4) by the second value, and

wherein, in the case where the road-surface detector has detected that the road surface which is present in the traveling direction of the vehicle descends rightward, the determination processor is configured to:
calculate a third value so that the third value increases as an inclination angle of the road surface with respect to the horizontal plane increases;
calculate a fourth value so that the fourth value increases as the inclination angle of the road surface with respect to the horizontal plane increases;
increase the absolute value of the first roll angle threshold (D1) and the absolute value of the second roll angle threshold (D2) by the third value;
increase the absolute value of the first roll velocity threshold (V1) and the absolute value of the second roll velocity threshold (V2) by the fourth value;
decrease the absolute value of the third roll angle threshold (D3) and the absolute value of the fourth roll angle threshold (D4) by the third value; and
decrease the absolute value of the third roll velocity threshold (V3) and the absolute value of the fourth roll velocity threshold (V4) by the fourth value.
