摘要： A roll angular velocity sensor (20) and a lateral velocity sensor (42) are operatively coupled to a processor (26), which generates a signal for controlling a safety restraint system (30, 32, 36, 38, 39, 40) responsive to measures of roll angular velocity and lateral velocity. In one embodiment, the processor (26) delays or inhibits the deployment of the safety restraint system (30) 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 (42), 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 separate front wheel speed sensors.

摘要： A roll angular velocity sensor (20) and an occupant sensor (42, 56.1, 56.2, 60.1, 60.2) are operatively coupled to a processor (26), which provides for detecting a rollover condition responsive to a measure of roll angular velocity and controlling a safety restraint system (30, 30.1, 30.2, 32.1, 32.2, 36.1, 36.2, 38.1, 38.2, 39.1, 39.2, 40.1, 40.2) responsive thereto, wherein a detection criteria associated with the rollover detection process is responsive to a signal from the occupant sensor. In one embodiment, a closure time is estimated from estimates or measurements of occupant velocity or acceleration, and the estimated closure time is compared with a threshold. If the estimated closure time is less than the threshold, activation of the safety restraint system is either inhibited or advanced relative to that otherwise provided by the rollover detection process alone. Otherwise, the activation may be delayed to provide additional time for the rollover detection.
