Lateral undulation Operation for Four Wheel Steered Vehicles with Vertical Suspension Control
The weigh of a vehicle body may be shifted onto selected wheels using the adjustable suspension systems of the vehicle to induce an undulating motion sequence of the vehicle. This may aid the vehicle to regain traction when a wheel is stuck. A first wheel may be turned in a first direction and more of the vehicle weight may be shifted onto the first wheel, while spinning one or more wheels, then this may be repeated for each wheel of the vehicle sequentially. More or less torque may be applied to the wheel onto which more of the vehicle's weight is shifted. The four-wheel sequence may be done at a predefined cadence and repeated as necessary. Also, based on terrain depth sensor signaling, an optimal weight distribution of the vehicle may be determined to aid vehicle movement on a hilly or off-road terrain.
