Abstract
System and method for determining vehicle speed of a wheel. The system including an electronic stability controller, an occupancy restraint controller, and an actuation controller coupled to a communication bus. The electronic stability controller including a wheel speed sensor to determine a first vehicle speed. The occupancy restraint controller including a vertical acceleration sensor to sense a vertical acceleration of the vehicle and a longitudinal acceleration sensor to sense a longitudinal acceleration of the vehicle. The actuation controller configured to determine a second vehicle speed using the vertical acceleration and the longitudinal acceleration of the vehicle. validate the second vehicle speed when the difference between the first vehicle speed and the second vehicle speed is less than a threshold, and use the first vehicle speed when the difference between the first vehicle and the second vehicle speed is greater than a threshold.
