Problems solved by technology

[0003] At present, the gear shifting control methods mostly use TCU (Transmission Control Unit, automatic transmission control unit) to control the gear shifting of vehicles with multi-way valves. Poor coordination between gear actuators, frequent misoperations of shift forks, poor work efficiency and execution accuracy, and lack of effective fault detection methods during the operation of multi-way valves, which is not conducive to the improvement of driving safety

Embodiment 1

[0040] figure 1 It is a flow chart of a vehicle gear shift control method in Embodiment 1 of the present invention. This embodiment is applicable to the situation where the automatic transmission control unit shifts gears of the vehicle through a multi-way valve. The method can be executed by the vehicle gear shift control device, which can be implemented in the form of software and / or hardware, and can be configured in electronic equipment. Such as figure 1 As shown, the method specifically includes:

[0041] S110. In response to the shift command including the target gear, set the multi-way valve control state as the target state according to the shift command and the preset gear multi-way valve control relationship table, for passing through the The multi-way valve performs a set operation.

[0042] Wherein, the shift instruction is input by the user through the input device or automatically generated by the electronic device based on the analysis of the road conditions....

Embodiment 2

[0066] figure 2 It is a flow chart of the vehicle gear shift control method in Embodiment 2 of the present invention. This embodiment is further optimized on the basis of the above Embodiment 1. Optionally, the method further includes: faulting the multi-way valve detection to obtain a fault detection result; if the multi-way valve is faulty, the control state of the multi-way valve is set to a prohibited control state, and the fault of the multi-way valve is processed in the prohibited control state.

[0067] Such as figure 2 As shown, the method includes:

[0068] S210. Perform fault detection on the multi-way valve to obtain a fault detection result;

[0069] In the process of TCU controlling the multi-way valve, the influence of factors such as electrical conditions, temperature conditions, main oil circuit pressure and execution status on the multi-way valve is fully considered. The TCU also performs real-time detection of the effective state of the multi-way valve. A...

Embodiment 3

[0081] image 3 It is a structural schematic diagram of a vehicle shift control device in Embodiment 3 of the present invention. This embodiment is applicable to the situation where the automatic transmission control unit shifts the gear of the vehicle through a multi-way valve. The device can be implemented by software and / or hardware, and can be configured in electronic equipment.

[0082] Such as image 3 As shown, the device may include: a multi-way valve target state setting module 310 , a multi-way valve setting judgment module 320 , a first multi-way valve control state keeping module 330 and a second multi-way valve control state keeping module 340 .

[0083] The multi-way valve target state setting module 310 is configured to set the multi-way valve control state as the target state according to the shift command and the preset gear multi-way valve control relationship table in response to the shift command including the target gear , for performing a setting operat...

Abstract

The embodiment of the invention discloses a vehicle gear shift control method, device, equipment and storage medium. The vehicle gear shift control method includes: in response to a gear shift instruction including a target gear, according to the gear shift instruction and the preset gear multi-way valve control relationship table, setting the multi-way valve control state as the target state, for The state is set through the multi-way valve; judge whether the multi-way valve is set; if the multi-way valve is set, keep the multi-way valve control state unchanged during the shift execution time to make the transmission shift; When it is detected that the gear shifting of the transmission is completed, the control state of the multi-way valve is kept unchanged within the first preset time period to keep the multi-way valve stable. The embodiment of the present invention introduces control strategies such as the multi-way valve switching state control mechanism and delayed closing, which realizes effective coordination between the gear selection multi-way valve and the gear shift actuator, avoids the wrong action of the shift fork, and improves the Work efficiency and execution accuracy.

Description

technical field [0001] The present invention relates to the technical field of vehicle transmissions, in particular to a vehicle gear shift control method, device, equipment and storage medium. Background technique [0002] With the development of automobile industry technology, more and more automatic transmissions are used in passenger cars. Among many types of automatic transmissions, dual-clutch automatic transmission stands out among many automatic transmissions due to its advantages of high transmission efficiency, quick shifting, and low cost, and has become a research hotspot for many manufacturers. In the dual-clutch automatic transmission electronic control system, the shift control is the most important, which determines the driving quality of the dual-clutch automatic transmission. [0003] At present, the gear shifting control methods mostly use TCU (Transmission Control Unit, automatic transmission control unit) to control the gear shifting of vehicles with mu...
