Problems solved by technology

It should be understood that at the same time that the gap closes when torque is transferred from the engine to the wheels, more gaps (eg, larger gaps) may also delay the vehicle's ability to accelerate

Abstract

A vehicle and method are provided. The vehicle includes a system and method for limiting the slip of the wheels. In an embodiment, the system holds the brakes based on an acceleration characteristic measured by a sensor. In another embodiment, the system includes a transmission controller that applies an adjustment to limit an amount of clutch slip as the clutch temperature changes to change in clutch performance to reduce wheel slip. In another embodiment, the system monitors a wheel slip signal from a sensor and compares the wheel slip to a target slip value and controls clutch slip of the transmission clutch to maintain engine output torque during acceleration. In another embodiment, in response to an anticipated vehicle launch event, a drive motor applies a first torque to the input shaft to adjust a gear backlash of the differential unit.
