摘要： A vehicle safety system (20) includes a controller (24) that verifies the plausibility of a roll angle indication obtained by processing a roll angular rate sensor (26) output. The controller (24) determines whether an acceleration value corresponding to the roll angle indication is within an expected range. In a disclosed example, the controller (24) utilizes a vertical acceleration value and a first expected range and a lateral acceleration value and a second expected range. When both of the acceleration values are outside of the respective expected range, the controller determines that the roll angle indication is invalid.

摘要： An air bag system (12) provides a central controller (14), a multiple of satellite sensors (16) and a multiple of deployable air bags (18). The central controller (14) runs the impact event algorithms. The number of satellites which are allowed to activate algorithms at any one time is limited. The minimum number of satellites required for full protection is the maximum number of satellite sensors allowed to wake up an impact event algorithm at any one time. An order for algorithm wake is also specified since the number of algorithms allowed is less than the total number of satellite sensors.

摘要： A distributed sensing system and method improves sensing of events that may require restraint deployment in a vehicle by distinguishing between deployment events and non-deployment events using data from more than one sensor.A transmission check process continuously monitors an incoming signal from a sensor and counts the number of data samples that exceed a selected value using a counter. If the counter value exceeds a selected threshold, the system indicates that the transmission check is fulfilled and allows deployment of the restraint.A correlation acceleration difference (CAD) algorithm calculates a CAD term corresponding to a degree of intrusion of a foreign object into a vehicle at a given time. Acceleration data from sensors disposed at supporting sides of the vehicle are checked if they respond to an event, and the absolute values of the acceleration data are subtracted from each other to obtain an absolute difference from which the CAD term is calculated.A method of reducing runtime in a system algorithm prioritizes calculations so that they are conducted on the side having the higher likelihood of having conditions requiring restraint deployment. Prioritizing calculations may also avoid refiring on a side that has already deployed a restraint, reducing the total number of calculations that the system needs to conduct.A method of evaluating a plausibility that a fire decision from a given sensor is the result of an event necessitating deployment of a restraint includes a plausibility check that checking the states of other sensors in the system before issuing a restraint firing request. The specific terms used in the plausibility check can be adjusted to accommodate different vehicle hardware configurations, vehicle setups and requirements.

摘要翻译： 分布式感测系统和方法通过使用来自多个传感器的数据区分部署事件和非部署事件来改善可能需要在车辆中进行限制部署的事件的感测。 传输检查过程连续监测来自传感器的输入信号，并使用计数器对超过选定值的数据采样数进行计数。 如果计数器值超过所选择的阈值，则系统指示传输检查已满足并允许部署约束。 相关加速度差（CAD）算法计算在给定时间对应于异物进入车辆的程度的CAD术语。 检查设置在车辆的支撑侧的传感器的加速度数据是否响应于事件，并且将加速度数据的绝对值相互减去以获得计算CAD项的绝对差。 一种减少系统算法中运行时间的方法对计算进行优先级排序，使得它们在具有需要约束部署的条件的较高可能性的一侧进行。 计算的优先顺序也可以避免在已经部署了约束的一方进行重新计算，减少系统需要进行的计算总数。 评估来自给定传感器的火灾决定是否需要部署约束的事件的结果的可信性的方法包括在发出限制发射请求之前检查系统中其他传感器的状态的合理性检查。 可以调整真实性检查中使用的具体术语，以适应不同的车辆硬件配置，车辆设置和要求。

摘要： A vehicle occupant classification system categorizes vehicle occupants into various classes such as adult, child, infant, etc. to provide variable control for a vehicle restraint system such as an airbag. The classification system utilizes sensors that are installed in various locations in the vehicle. The sensors are used to generate a three-dimensional profile for the vehicle occupant. Various factors can affect the accuracy of this three-dimensional profile. Fuzzy logic is used to reduce some of the inaccuracies by providing multiple decision levels for various stages of the classification. Inaccuracies are also caused by sensors shifting within the system from their original position. This condition creates offset and the system evaluates this offset and generates a correction factor to provide a more accurate three-dimensional profile. Electrically erasable programmable read-only memory is used to reduce complications and inaccuracies associated with seat occupant weight sensors that have mounting configurations that vary depending upon the vehicle.
