Abstract
Steering a vehicle in an electronic steering mode of operation that includes a front axle steering system, a rear axle steering system, one or more vehicle environment sensors, and a controller operatively coupled with the front axle steering system, the rear axle steering system, and the vehicle environment sensors. Commanding the vehicle to operate at a desired vehicle speed, detecting a lateral force acting on the vehicle in response to input from the vehicle environment sensors, and determining an actual lateral acceleration of the vehicle and a predicted lateral acceleration of the vehicle from the desired vehicle speed. Determining a lateral acceleration error by comparing the predicted lateral acceleration to the actual lateral acceleration, and determining if the lateral acceleration error exceeds a lateral acceleration limit, then turning both of the front axle steering system and the rear axle steering system to a crab steering correction angle.
