Automatic driving vehicle longitudinal control method and system considering multiple factors

The invention provides an automatic driving vehicle longitudinal control method considering multiple factors. The method comprises the steps that S1, control state information needed by automatic driving vehicle longitudinal control is obtained through a vehicle-mounted sensing device; s2, selecting corresponding longitudinal control strategies under different working conditions based on the acquired control state information and the motion state of the other vehicle; s3, considering the driving comfort, the weather condition and the road vehicle speed limit value, and setting conditional constraints for the acceleration and the target cruising vehicle speed; and S4, aiming at different control strategies, calculating a target acceleration (deceleration) speed for longitudinal control of the automatic driving vehicle by utilizing a control algorithm, and outputting the target acceleration (deceleration) speed for controlling acceleration (deceleration) of the vehicle to finish longitudinal control.
