Abstract
Methods and systems are provided for launching a vehicle from rest in order to maximize performance for the vehicle launch event. In one example, a method comprises, in preparation of a launch of the vehicle driven by an engine from a resting state, rotating a set of vehicle tires via a controller by adjusting a torque of the engine while vehicle brakes are applied for a duration that is a function of real-time pressure sensor readings of the set of tires. In this way, tire temperature may be determined based on the real-time pressure sensor readings in order to control tire temperature to an optimal tire temperature for the launch event, where the optimal tire temperature is based on a coefficient of friction of the road surface the vehicle is launching from, and where the optimal tire temperature provides for optimal grip for the vehicle launch.
