    摘要: Data on an impending curve, speed, and acceleration of a vehicle are collected. A curve attention output that is a measure of the vehicle speed, the vehicle acceleration, and the curvature of the impending curve is determined based at least in part on the data. An output mechanism in a wearable device is activated at a first intensity when the curve attention output exceeds or is equal to a first threshold and below a second threshold. The output mechanism is activated at a second intensity when the curve attention output exceeds or is equal to the second threshold and below a third threshold.

    摘要: A time to lane crossing that is a measure of a time for a vehicle to cross from a lane to another lane, is determined. A lane negotiation characteristic that is a measure of a mean vehicle offset front the lane, is determined. A first mechanism is actuated in a wearable device when the time to lane crossing is below a first threshold and the lane negotiation characteristic exceeds a second threshold. A second mechanism is actuated in the vehicle when a lane negotiation controller detects an imminent lane departure.
