Abstract
The present disclosure provides'vehicle operation around an obstacle '. A computer includes a processor and a memory, and the memory stores instructions executable by the processor to: formulate a plurality of constraints; determining a final input modification to the nominal input that minimizes a cost function limited by the constraints; and actuating a component of the vehicle as a function of the nominal input and the final input modification. Each constraint is indicative of a respective obstacle relative to the vehicle. Each constraint is represented as a linear inequality in a two-dimensional space in dimensions of acceleration and steering angle. The nominal input includes a nominal acceleration and a nominal steering angle. The final input modification includes a final change to the nominal acceleration and a final change to the nominal steering angle. The computer determines the final input modification by individually calculating the cost function for a plurality of potential input modifications on the constraints.
