Embodiment 1

[0058] This embodiment 1 is used to illustrate dangerous situations such as rear-end collision or collision caused by excessive speed-up of the vehicle due to the driver still stepping on the accelerator when shifting gears in a traffic jam environment. In this embodiment, the logic processing unit 302 judges the gear and the speed of the vehicle on the current road according to the average driving speed and the current speed of the current road where the vehicle is located.

[0059] When the driver makes a misoperation and the current vehicle speed exceeds the average driving speed by a large amount in a short period of time, and the target gear judging module 2023 judges that the target gear is a high-speed gear according to the vehicle speed and the motor speed, it exceeds the average driving speed by 1.5 times within 1 second. The speed and vehicle condition correction module 3024 corrects the current vehicle speed to the average driving speed, the motor correction module 3...

Embodiment 2

[0061] This embodiment 2 is used to illustrate the dangerous situation that the vehicle speed is too fast due to the negligence or misoperation of the driver when the vehicle passes through an intersection or a pedestrian crosswalk. In this embodiment, the logic processing unit 302 judges the gear position and speed of the vehicle on the current road according to the intersection information and pedestrian crossing line information of the current road where the vehicle is located, and the current vehicle speed.

[0062] When the driver makes a misoperation or negligence, and the vehicle is still running at a high speed when approaching an intersection or a crosswalk line, the vehicle condition correction module 3024 reduces the current vehicle speed, the motor correction module 3025 motor outputs power, and the gear position correction module 3026 corrects the target gear position for low gear. The logic processing unit 302 of Embodiment 2 can significantly reduce the speed of...

Embodiment 3

[0064] This embodiment 3 is used to illustrate dangerous situations such as overspeeding due to drivers on roads with traffic signs and speed limits. In this embodiment, the logic processing unit 302 judges the gear and the speed of the vehicle on the current road according to the average driving speed and the current speed of the current road where the vehicle is located.

[0065] When the driver makes a misoperation and the current vehicle speed exceeds the limited speed in a short time, and the target gear judging module 2023 judges that the target gear is a high gear according to the vehicle speed and the motor speed, the vehicle condition correction module 3024 corrects the current vehicle speed to the average driving speed. Speed, the motor output power of the motor correction module 3025, and the gear position correction module 3026 correct the target gear position to a low gear position. The logic processing unit 302 of the third embodiment corrects accident-prone erro...

Abstract

The invention provides an adaptive automatic speed changing and gear shifting intelligent control system. The adaptive automatic speed changing and gear shifting intelligent control system comprises amain driving motor, a gear shifting actuator, an intelligent controller and a gearbox, wherein the main driving motor and the gearbox are connected through splines, and the gear shifting operation ofthe gear shifting actuator is controlled by the intelligent controller; the intelligent controller comprises an information acquisition unit, a logical processing unit, a gear shifting driving circuit and a main motor driving circuit; vehicle driving data, power supply data and traffic data are input into the logical processing unit through the information acquisition unit, and information is processed by the logical processing unit so as to obtain a target gear suitable for the current main driving motor; the gear shifting driving circuit is connected with the gear shifting actuator, and a gear shifting associative ring in the gear shifting actuator is adaptively adjusted to move to the position of the target gear by the gear shifting driving circuit; and the main motor driving circuit is connected with the main driving motor, and the rotating speed of the main driving motor is adaptively controlled to match with the gear shifting associative ring to switch in the target gear by themain motor driving circuit according to the target gear.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and relates to a vehicle shift control technology, in particular to an adaptive automatic transmission control system and a control method thereof. Background technique [0002] Electric vehicles are increasingly favored by consumers, and in response to the national environmental protection policy of energy conservation, emission reduction, and green environmental protection, the market share of electric vehicles has gradually increased. The gearbox is an important part of the vehicle transmission system, and its performance directly affects the performance of the transmission system as well as the driving experience and safety performance of the vehicle. [0003] The transmission systems of the original fuel vehicles can be classified into manual transmission systems and automatic transmission systems. In a classic manual transmission system, the shift lever is directly connected to the transm...
