Driving force control system and saddled vehicle

A driving force control system including: an absolute bank angle detector (51) configured to detect an absolute bank angle (¸a) that is the absolute value of a bank angle of a vehicle (1); a calculation circuit (51) configured to calculate a relative bank angle (¸r) that is the vehicle's relative angle with respect to a maximum absolute bank angle (¸m) that is a recently acquired maximum value of the absolute bank angle (¸a); and a controller (31) configured to control the driving force of the vehicle based on the relative bank angle (¸r).
