A vehicle lane keeping control system calculates a feedforward control amount on the basis of a vehicle traveling path, calculates a first positional deviation amount between a vehicle and a target course at a first forward attention point when the vehicle travels in a straight line to the first forward attention point if a steering torque exceeds a threshold value, calculates a first lateral position feedback control amount, calculates an amount of deviation between an estimated vehicle traveling path and the target course at a second forward attention point remote from the first forward attention point if the first lateral position feedback control amount is lower than the threshold value, calculates a second lateral position feedback control amount, and calculates an electric motor current value by using at least the feedforward control amount and one of the first and second lateral position feedback amounts.
