The invention discloses a suspension front wheel toe-in angle control system and method combined with an automatic driving module in the field of vehicle suspension control. An information processingmodule judges whether the vehicle speed, the acceleration and the steering wheel angle information at the next moment sent by an automatic driving module are received or not; a target toe-in judgmentmodule firstly calculates a first toe-in angle, and then calculates a second toe-in angle on the basis of the first toe-in angle; if the information processing module does not receive the informationof the automatic driving module, the target toe-in judgment module takes the second toe-in angle as a target toe-in angle; if the information is received, a third toe-in angle is calculated firstly, then a fourth toe-in angle is calculated on the basis of the third toe-in angle, and the fourth toe-in angle serves as a target toe-in angle. The vehicle toe-in angle can be adjusted according to the sprung mass and the tire tem
