Abstract
A roll angular velocity sensor and a lateral velocity sensor are operatively coupled to a processor, which generates a signal for controlling a safety restraint system responsive to measures of roll angular velocity and lateral velocity. In one embodiment, the processor delays or inhibits the deployment of the safety restraint system responsive to a measure responsive to the measure of lateral velocity, either alone or in combination with a measure of longitudinal velocity. In another embodiment, a deployment threshold is responsive to the measure of lateral velocity. The lateral velocity may be measured by a lateral velocity sensor, or estimated responsive to measures of lateral acceleration, vehicle turn radius, and either longitudinal velocity or yaw angular velocity, wherein the turn radius is estimated from either a measure of steering angle, a measure of front tire angle, or measures of forward velocity from separate front wheel speed sensors.
