摘要: A support system includes a primary actuator that transfers force between a sprung mass and an unsprung mass. A control system operates the primary actuator to provide additional control when a damper exceeds a capacity threshold. The control system changes the capacity threshold according to the environmental condition.

摘要: A vehicle includes a vehicle body, a wheel, a suspension system that supports the wheel relative to the vehicle body, a sensing system for determining an environmental condition ahead of the vehicle and a control system. The suspension system includes a primary actuator that transfers force between the wheel and the vehicle body, and a wheel hop damper that includes a moving mass and that transfers force between the wheel and the moving mass independent of the vehicle body to inhibit resonance of an unsprung mass formed by the wheel and a portion of the suspension system coupled thereto. The control system operates the primary actuator to provide additional secondary ride control when the wheel hop damper exceeds a capacity threshold. The control system changes the capacity threshold according to the environmental condition. The wheel hop damper may be a reaction mass actuator or a tuned mass damper.

摘要: A method includes determining temperature values for roadway areas ahead of a vehicle, determining lubricant state values for the roadway areas, and determining lubricant thickness values for the roadway areas. The method also includes determining a tire-road friction estimate for each of the roadway areas using the temperature values, the lubricant state values, and the lubricant thickness values, and defining a friction map that relates the tire-road friction estimates to the roadway areas. The method also includes determining a motion plan based at least in part on the friction map, and controlling the vehicle based on the motion plan.
