Abstract
A vehicle steering intervention system and method prevents a loss of vehicle control condition or a vehicle rollover condition. The system includes a driver input torque sensor for sensing torque applied by a driver to a steering wheel, a steering angle sensor for sensing a steering angle, and a speed determination device for determining a vehicle speed. An electronic power steering unit includes an electronic processor and a memory. The electronic power steering unit determines a vehicle steering intervention threshold based on the torque sensed, the steering angle, and the vehicle speed. The electronic power steering unit predicts whether the vehicle steering intervention threshold will be exceeded within a predetermined time based on a torque gradient and/or a steering angle gradient. When the vehicle steering intervention threshold is predicted to be exceeded, the electronic power steering unit reduces a power steering assist and/or provides a counter steer force.
