Abstract
Techniques for managing wheel slip in a through-the-road hybrid vehicle comprise detecting a front wheel slip event based on measured rotational speeds of front wheels, determining a likelihood of a subsequent rear wheel slip event, when the front wheel slip event has ended and the likelihood of the subsequent rear wheel slip event satisfies a calibratable threshold, adjusting a front/rear axle torque split and pre-loading at least one of an engine and a belt-driven starter generator (BSG) unit coupled to a crankshaft of the engine to compensate for a torque drop that is predicted to occur during the rear wheel slip event, and re-adjusting the front/rear axle torque split and pre-unloading at least one of the engine and the BSG unit such that a drop in torque output at a front axle aligns with an end of the rear wheel slip event.
