Apparatus for determining vehicle rollover risk
First Claim
1. A control apparatus for a vehicle, comprising a control unit including:
- a resultant acceleration information calculating section configured to calculate a resultant acceleration which is a synthesis of two orthogonal direction accelerations acted upon the vehicle;
a resultant jerk calculating section configured to calculate a resultant jerk of at least one of a change rate of the resultant acceleration with respect to time and of the synthesis of change rates of both of the two orthogonal direction accelerations with respect to time; and
a rollover tendency determining section configured to determine a tendency of rollover of the vehicle using the calculated resultant jerk.

Abstract
A control apparatus for a vehicle, comprising a control unit having: a resultant acceleration information calculating section (100c) configured to calculate a resultant acceleration which is a synthesis of two direction accelerations acted upon the vehicle; a resultant jerk calculating section (100c2) configured to calculate a resultant jerk of at least one of change rates of the two directional accelerations with respect to time and a change rate of the resultant acceleration with respect to time; and a rollover tendency determining section (100e) configured to determine a tendency of rollover of the vehicle using at least one of the calculated resultant acceleration and the calculated resultant jerk.
