Roll-over suppressing control apparatus for a vehicle
First Claim
1. A roll-over suppressing control apparatus for a vehicle, comprising:
- a braking mechanism for braking wheels of said vehicle;
parameter value detection means for detecting a value of a parameter corresponding to a rolling state of said vehicle; and
roll-over suppressing control means for controlling said braking mechanism,wherein if the parameter value detected by said parameter value detection means upon turning of said vehicle becomes equal to or higher than a control starting threshold value, then said roll-over supressing control means determines that said vehicle is in an excessively rolling state and controls said braking mechanism to apply a braking force to said wheels,wherein the control starting threshold value is set to different values depending upon whether a steering wheel of said vehicle is rotated in one direction or multiple directions.

Abstract
The invention provides a roll-over suppressing control apparatus for a vehicle which can make a decision of a start of roll suppressing control appropriately in response to the degree of the possibility of turning over on its side of the vehicle. The roll-over suppressing control apparatus includes a braking mechanism for braking wheels of the vehicle, a roll rate sensor for detecting a roll rate of the vehicle, and a roll-over suppressing control section for controlling the braking mechanism so that, if the roll rate detected upon turning of the vehicle becomes equal to or higher than a control starting threshold value, then it is decided that the vehicle is in an excessively rolling state and braking force is applied to the wheels. The control starting threshold value is set to different values depending upon different types of turning of the vehicle (depending upon whether the turning is sudden steering back turning, moderate steering back turning or one-directional turning).

4. A roll-over suppressing control apparatus for a vehicle, comprising:
-
a braking mechanism for braking wheels of said vehicle; parameter value detection means for detecting a value of parameter corresponding to a rolling state of said vehicle; and roll-over suppressing control means for controlling said braking mechanism, wherein if the parameter value detected by said parameter value detection means upon turning of said vehicle becomes equal to or higher than a control starting threshold value, then said roll-over suppressing control means determines that said vehicle is in an excessively rolling state and controls said braking mechanism to apply a braking force to said wheels, wherein the control starting threshold value is set to different values depending upon different types of turning of said vehicle, and wherein the types of turning of said vehicle include one-directional turning where said vehicle turns only in one direction and steering back turning where the turning direction is changed over halfway. - View Dependent Claims (5, 6, 7, 8, 9)
