1. A system, comprising:
one or more processors and memory to:
detect an amount of torque requested for a vehicle;
determine a friction level associated with a surface on which the vehicle traverses;
select, based on the amount of torque requested for the vehicle and the friction level, a first slip target modifier for a first non-zero slip target for wheel slip corresponding to a first electric motor and a second slip target modifier for a second non-zero slip target for wheel slip corresponding to a second electric motor;
perform, using the amount of torque and the friction level, a lookup in a data structure stored in the memory to select the first slip target modifier and the second slip target modifier; and
adjust, based on the first slip target modifier, the first non-zero slip target corresponding to the first electric motor used by a traction control system of the vehicle, and adjust, based on the second slip target modifier, the second non-zero slip target corresponding to the second electric motor used by the traction control system.
