A method is provided which determines a time to a collision and a field of safe travel, and which selects one of a first and a second haptic output based on the field of safe travel and a predetermined time threshold (for example three seconds). A first haptic output is delivered via a steering wheel when the time to collision is greater than the threshold and a second haptic output is delivered via the steering wheel when the time to collision is less than or equal to the threshold. The method may be used to assist with vehicle lane changes. The haptic outputs may have different levels of torque and/or different patterns based on the time to collision. The time to collision and a field of safe travel may optionally be displayed.
