Occupant restraint system and control method with variable sensor rate and/or sample rate

摘要

An occupant restraint system (10), and an associated control method, for a vehicle (16). The system (10) includes an actuatable occupant restraint device (18). An ultrasound sensor (34) senses an occupant condition and provides a signal (38) indicative thereof. An ultrasound signal sampler function (46) of a controller (26) samples the signal (38) at a sample rate. A restraint control determination function (50) of the controller (26) makes determinations regarding control of the restraint device (18) using the signal samples. A rate determination function (52) determines the sensor and sample rates using the signal samples.
