Problems solved by technology

[0004] At present, the adaptive cruise system will frequently shift gears in the process of controlling the acceleration of the vehicle, and the shifting will cause the vehicle to falter, especially in dual-clutch transmission vehicles, which greatly affects the steering control of the automatic lane change system on the steering wheel. Stability and vehicle driving experience

Abstract

The present invention relates to a control method, system, control device, and storage medium for automatic lane change of a vehicle. The method includes: when the vehicle enters an adaptive cruise acceleration state, obtaining the corresponding first target demand torque T according to the target acceleration 0 and the virtual throttle opening; determine whether the vehicle will perform an automatic lane change according to the virtual throttle opening, the current vehicle speed and the current gear position, and if so, the first target demand torque T according to the shift information 0 Adjust to obtain the second target demand torque T 1 , and the second target demand torque T 1 sent to the engine control unit, if not, the first target demand torque T 0 Sent to the engine control unit. The system corresponds to the method, the control device and the storage medium include a program for executing the method, and the implementation of the present invention can avoid frequent gear shifting during the automatic lane change process of the vehicle.

Description

technical field [0001] The invention relates to the technical field of parking control, in particular to a control method and system for automatic lane change of a vehicle, a control device, and a storage medium. Background technique [0002] Adaptive Cruise Control (ACC for short) means that after the driver sets the target speed, the system will control the vehicle to accelerate to reach the target speed; at the same time, the sensor will monitor the driving conditions ahead in real time, if there is a target vehicle in front When the vehicle is running, the system will send a control command to the engine or braking system after calculation and judgment to reduce the speed of the vehicle so that the vehicle and the vehicle in front can maintain a safe driving distance and realize the function of following the vehicle. The existing adaptive cruise system will calculate the target acceleration and required torque according to the driver's set speed, and then send the requir...
