Abstract
A method for vehicular control includes providing a forward viewing camera, a yaw rate sensor, a longitudinal accelerometer, a speed sensor and a control system at the vehicle. While the vehicle is moving, an angular rotational velocity of the vehicle about a local vertical axis is determined, a yaw rate offset is determined, and a longitudinal acceleration is determined. A corrected yaw rate is determined responsive to the determined yaw rate offset of the yaw rate sensor and the determined longitudinal acceleration of the vehicle. The control system determines a projected driving path of the vehicle based at least in part on the determined corrected yaw rate. A hazard condition ahead of the vehicle in the projected driving path is determined at least in part responsive to detecting an object and to the projected driving path. The system automatically applies the brakes of the vehicle responsive to the determined hazard condition.
