1. A system, comprising:
one or more processors coupled with memory to:
determine, for a first time interval, a difference between an expected acceleration of a vehicle and an actual acceleration of the vehicle measured via one or more sensors of the vehicle;
detect, for the first time interval, a condition for the vehicle to increase a first slip target set for the vehicle;
increase the first slip target set for the vehicle to a second slip target responsive to the difference greater than or equal to a threshold and the detection of the condition; and
generate a control signal to cause a motor to increase a torque applied during a second time interval subsequent to the first time interval, responsive to the increase from the first slip target to the second slip target.
