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 invention relates to a vehicle automatic lane changing control method and system, control equipment and a storage medium, and the method comprises the steps: obtaining a corresponding first targetdemand torque T0 and a virtual accelerator opening degree according to a target acceleration when a vehicle enters an adaptive cruise acceleration state; according to the virtual accelerator openingdegree, the current vehicle speed and the current gear, judging whether gear shifting is carried out when the vehicle executes automatic lane changing, if yes, adjusting the first target required torque T0 according to gear shifting information to obtain second target required torque T1, sending the second target required torque T1 to an engine control unit, and if not, sending the first target required torque T0 to an engine control unit. The system corresponds to the method, the control equipment and the storage medium comprise programs used for executing the method, and frequent gear shifting in the automatic lane changing process of the vehicle can be avoided.

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...
