VEHICLE CONTROL SYSTEM

Abstract:

A vehicle control system includes a controller comprising one or more processors. The controller is configured to determine a respective force exerted on a route segment by a first wheel of a plurality of wheels of a vehicle and obtain a respective available adhesion value for the first wheel at an interface with the route segment. The controller is configured to determine a respective effective adhesion value to utilize for driving rotation of the first wheel. The effective adhesion value is within a designated wheelslip margin relative to the available adhesion value for the first wheel without exceeding the available adhesion value. The controller is further configured to assign a torque setting to rotate the first wheel based at least in part on the respective force exerted on the route segment by the first wheel and the effective adhesion value for the first wheel.
