A passenger car auxiliary driving adaptive cruise control method and system

Abstract

The application provides a passenger car auxiliary driving adaptive cruise control method and system, and belongs to the technical field of auxiliary driving, and comprises the following steps: acquiring sensing information and vehicle state information around a vehicle; performing main target locking based on the sensing information and target screening; adopting different adaptive control algorithms for cruise according to whether the main target exists; if the main target exists, a double-loop PID acceleration model is adopted for control and a first acceleration is output; the first acceleration is filtered and matched to different main scene control torques and throttle opening degrees, the whole vehicle is controlled to accelerate or decelerate to reach a state of adaptive adjustment of the following vehicle speed; if the main target does not exist, a segmented PID acceleration model is adopted for control and a second acceleration is output, the control torque and the throttle opening degree are controlled to reach the control of the vehicle speed to the set target speed. Through the double-loop proportional correction variable integral PID dynamic adjustment advantage, the application realizes the rapid and accurate control of the vehicle speed.
