Description

Technical Field

[0001] The present invention relates to the technical field of vehicle electronic control system development, and in particular to an intelligent driving gear arbitration method based on a non-self-resetting gear shifting mechanism. Background Art

[0002] A non-self-resetting shift mechanism is an operating mechanism that is fixed in the current gear position after manual operation. Common ones include traditional gear lever shift mechanisms, mechanical knob switches, paddle shift switches, etc. In the automotive industry, especially the commercial vehicle industry, paddle shift switches or knob shift switches are still relatively popular.

[0003] But now the development of intelligent driving is very rapid. The intelligent driving control signal is an intelligent driving enable and activation signal issued by the intelligent driving system. Usually 0 means inactive (enabled) and 1 means active (enabled).

[0004] When the above two are combined, there will be a problem. Since the gear shifting mechanism is mechanical, it will always stay in a certain gear, resulting in inconsistent gears when switching between manual and intelligent modes.

[0005] Although this problem can be solved by using a self-resetting shift mechanism, it requires changes in the design of the OEM and the operation method of the car owner.

[0006] A Chinese patent (publication date: November 15, 2022, publication number: CN115339457A) discloses a vehicle self-resetting torque adjustment method, which relates to automobile power control technology. The vehicle's load status is obtained in real time through the tire pressure calibration method, and the torque gear is automatically switched according to the vehicle's load status, and the torque gear after automatic switching is used as the target gear; if the target gear is not manually switched, the target gear is used as the current torque gear; if the target gear is manually switched, the gear after manual switching is used as the current torque gear. The present invention also discloses a vehicle self-resetting torque adjustment switch system. The present invention has automatic and manual torque gear switching functions, and is more intelligent, which not only ensures the vehicle's power performance, but also is beneficial to fuel consumption. However, the invention still requires the use of a self-resetting torque adjustment switch.

[0007] A Chinese patent (publication date: January 11, 2019, publication number: CN109177965A) discloses an intelligent vehicle auxiliary brake control system and a control method thereof. The system includes a vehicle controller, an engine controller, an automatic transmission controller, a hydraulic retarder controller, an instrument, a vehicle speed sensor, a self-resetting auxiliary brake graded control switch handle and an accelerator pedal on an automatic transmission vehicle; there is no automatic transmission controller on a manual transmission vehicle, but a clutch pedal micro switch and a transmission neutral switch are included. The control method includes: when the state requirements are met, the vehicle controller actively requests the engine controller to activate the engine brake; the vehicle controller sends a hydraulic retarder request activation signal corresponding to the gear, and the hydraulic retarder controller controls the hydraulic retarder to work; the real-time gear information is transmitted to the instrument, and the gear information is displayed to the driver in a graphical manner on the instrument; and the auxiliary brake control function is exited. The working efficiency of the auxiliary brake system is improved and the safety of vehicle driving is increased. However, the invention cannot solve the problem of gear inconsistency when switching between manual and intelligent modes. Summary of the invention

[0008] The purpose of the present invention is to address the deficiencies of the above-mentioned technology and to provide an intelligent driving gear arbitration method based on a non-self-resetting gear shift mechanism, which can safely decide and execute the switching between manual and intelligent driving modes, realize the system's operation requests regarding gears, and make abnormal judgments and reminders.

[0009] To achieve the above-mentioned purpose, the intelligent driving gear arbitration method based on the non-self-resetting gear shift mechanism designed by the present invention enters the intelligent driving mode when the intelligent driving enable signal changes from 0 to 1 and remains at 1, and only responds to the intelligent driving gear request; otherwise, the intelligent driving mode is exited, and only the manual gear request is responded to, and the manual operation mode is entered.

[0010] Preferably, when the intelligent driving enable signal is not activated, the system responds to the mechanical switch level signal output by the manual shift mechanism as an input signal of the shift actuator.

[0011] Preferably, when the smart driving enable signal is activated, the timeout status of the smart driving related message is continuously judged. When there is no timeout and the enable signal continues to be 1, it is judged to shift gears to enter the smart driving mode.

[0012] Preferably, after entering the intelligent driving mode, the manual shift mechanism is in the switch state before entering the intelligent driving mode, and maintains the output of the mechanical switch level signal.

[0013] Preferably, when the mechanical switch level signal of the manual shift mechanism and the gear request signal of the intelligent driving system are input simultaneously, only the intelligent driving gear request signal is responded to, and the mechanical switch level signal of the manual shift mechanism is not responded to.

[0014] Preferably, the current gear position of the manual gear shift mechanism is fed back to the outside in real time.

[0015] Preferably, when exiting the intelligent driving mode, the shift controller does not receive an intelligent driving gear request and determines to enter the manual control mode.

[0016] Preferably, when entering the manual operation mode, the rising edge signal of the mechanical switch level signal is identified as a valid gear request signal.

[0017] Preferably, when exiting the intelligent driving mode, the actual gear position of the shift mechanism is detected to see if it is consistent with the current actual gear position of the transmission. If they are inconsistent, a reminder signal is issued, and the instrument makes a text reminder to remind the driver to restore the shift mechanism to the corresponding gear position. Only after the driver operates the manual shift mechanism can the manual shift mechanism issue a real shift request.

[0018] Preferably, in the intelligent driving mode, if a brake pedal signal is received, the intelligent driving is forced to exit, and after the brake signal returns to 0 and the rising edge of the intelligent driving enable signal is received, the intelligent driving mode is re-entered.

[0019] Compared with the prior art, the present invention has the following advantages: it can safely decide and execute the switching between manual and intelligent driving modes, realize the system's operation request on gear position, and make abnormal judgments and reminders.

Claims

1. An intelligent driving gear arbitration method based on a non-self-resetting gear shift mechanism, characterized in that: When the smart driving enable signal changes from 0 to 1 and remains at 1, the system enters the smart driving mode and responds only to smart driving gear requests. Otherwise, the system exits the smart driving mode and responds only to manual gear requests, entering the manual control mode. When the intelligent driving enable signal is not activated, the system responds to the mechanical switch level signal output by the manual shift mechanism as the input signal of the shift actuator. When the intelligent driving enable signal is activated, the system continuously judges the timeout status of the intelligent driving related message. When there is no timeout and the enable signal is continuously 1, it is judged that the gear shift enters the intelligent driving mode. After entering the intelligent driving mode, the manual shift mechanism is in the switch state before entering the intelligent driving mode, and maintains the output of the mechanical switch level signal. When the mechanical switch level signal of the manual shift mechanism and the gear position request signal of the intelligent driving system are input at the same time, it only responds to the intelligent driving gear position request signal, and does not respond to the mechanical switch level signal of the manual shift mechanism; When exiting the intelligent driving mode, the shift controller does not receive the intelligent driving gear request, and determines to enter the manual operation mode. When entering the manual operation mode, the rising edge signal of the mechanical switch level signal is identified as a valid gear request signal. When exiting the intelligent driving mode, it detects whether the actual gear position of the shift mechanism and the current actual gear position of the transmission are consistent. If they are inconsistent, a reminder signal is issued, and the instrument makes a text reminder to remind the driver to restore the shift mechanism to the corresponding gear. After the driver operates the manual shift mechanism, the manual shift mechanism can issue a real shift request.

2. The intelligent driving gear arbitration method based on the non-self-resetting gear shift mechanism according to claim 1, characterized in that: The current gear position of the manual shift mechanism is fed back to the outside in real time.

3. The intelligent driving gear arbitration method based on the non-self-resetting gear shift mechanism according to claim 1, characterized in that: In the smart driving mode, if the brake pedal signal is received, the smart driving will be forced to exit. After the brake signal returns to 0 and the rising edge of the smart driving enable signal is received, the smart driving mode will be re-entered.
