Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a signal control method for a transmission mechanism, a signal control device for a transmission mechanism, a vehicle, and a computer-readable storage medium. Background Art

[0002] The signal control of the transmission mechanism is very important for the driving safety of the vehicle. In related technologies, after the transmission is powered on and initialized, before receiving the neutral signal from the electronic shift controller, the current gear position is an invalid value. After the vehicle's handle is powered on and initialized, it is checked according to the current gear position status of the transmission. If it is an invalid value, a neutral signal is sent, allowing the transmission and the electronic shift controller to "shake hands" successfully, allowing the vehicle to start normally.

[0003] However, the above method will make the signal control of the speed change mechanism unstable. For example, when performing a "handshake", after the vehicle is powered on and off, because the transmission has a power-off delay, the electronic shift controller will receive a non-neutral gear signal when the transmission is powered on when it is powered on, when the transmission has not been successfully powered off. At this time, the electronic shift controller will not send a neutral "handshake" signal, resulting in a "handshake" failure and a handle activation failure. Summary of the Invention

[0025] The embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0026] For vehicle startup safety, automatic transmissions typically include a start interlock function. To prevent accidents caused by the driver accidentally engaging a gear by operating the handle before starting the vehicle, the transmission requires the electronic shift controller to signal neutral within a specified time after power-up before the engine can start normally. Electronic shift controllers can have monostable or multistable structures. For monostable electronic shift controllers without fixed gear positions (such as 360° infinitely variable knobs), the neutral signal issued after power-up requires certain logic checks. If the electronic shift controller consistently signals neutral after initialization, such as during a trip due to a brief circuit failure that causes the electronic shift controller to lose power, and then the handle resets to neutral after power-up, the transmission will shift to neutral, causing the vehicle to become unable to drive normally. Therefore, it is necessary to develop a reasonable signal control strategy for the transmission mechanism of such electronic shift controllers.

[0027] In related technologies, for example, after a transmission is powered on and initialized, but before receiving a neutral signal from the shifter, the current gear is invalid, meaning it's not in a normal gear. After a monostable lever with no gear position is powered on and initialized, it checks the transmission's current gear state. If it's in an abnormal gear, a neutral signal is sent, allowing the transmission and shifter to "shake hands" successfully and allowing the vehicle to start normally. If the current gear is a normal gear (such as P), the shifter does not send a neutral signal.

[0028] However, in some scenarios, the signal control strategy of the above-mentioned transmission mechanism has poor stability and accuracy. For example, if the transmission has a power-off delay strategy and the electronic shift controller is powered by the key (KL15), after the vehicle is powered off and the transmission has not entered the sleep period, the vehicle is quickly powered on again. The transmission is not successfully powered off, and the transmission's current gear signal is still a normal gear (such as P gear). During this period, the electronic shift controller is successfully powered off and stops sending messages. After powering on again, the electronic shift controller receives that the current gear of the transmission is a normal gear. According to the strategy, the electronic shift controller will not send a neutral "handshake" signal. At this time, the transmission will activate a handle fault because it did not receive the "handshake" signal from the electronic shift controller in the middle. The only way to eliminate this fault is to power off the key again, wait for the transmission to go into sleep, and then power on again, so that the electronic shift controller sends a neutral "handshake" signal to eliminate the fault.

[0029] For example, when the vehicle enters neutral and coasts during driving, the gear that actually meets the driver's intention is not neutral. At this time, if the handle is restarted due to wiring problems, the current gear of the transmission is detected to be neutral after startup, and a neutral signal will be sent to the transmission. After receiving the neutral signal, the transmission will control the vehicle to shift to neutral, resulting in the gear shift not matching the driver's intention. The vehicle may not be able to drive normally due to entering neutral, posing a safety hazard.

[0030] Therefore, the signal control method of the transmission mechanism of the embodiment of the present invention is adopted. By obtaining the target gear information when the transmission is powered on and initialized, the gear signal of the electronic shift controller and the transmission state is determined with more stable target gear information, and the vehicle start is controlled according to the state synchronization result to improve the stability and accuracy of the signal control of the transmission mechanism, ensure the correct interaction between the transmission and the electronic shift controller, and ensure the correctness of the gear instructions sent by the electronic shift controller during driving, thereby improving the user's car experience and car safety.

[0031] The following combination Figure 1 and Figure 2 A signal control method for a speed change mechanism according to an embodiment of the present invention is described.

[0032] like Figure 1 FIG. 1 is a flow chart of a signal control method for a transmission mechanism according to an embodiment of the present invention. The signal control method for a transmission mechanism according to the embodiment of the present invention comprises at least steps S1 to S3.

[0033] Step S1, obtaining target gear information of the transmission.

[0034] In an embodiment, the target gear information is the target gear position during transmission power-up initialization before the vehicle is powered on and started. For example, after the vehicle is powered on, the default gear position before the ignition is turned off (e.g., P or N) is retained. After the transmission is powered on and initialized, before receiving a neutral signal from the electronic shift controller, the current gear position is an invalid value, i.e., an abnormal gear position. During the initialization process, the transmission shifts from the invalid current gear position to the target gear position. The target gear position is typically initialized to neutral (N) by the transmission control unit as a safety reference. Therefore, before the vehicle is powered on and started, the target gear position information can be considered to be neutral. Obtaining the transmission's target gear information prepares for signal control of the transmission.

[0035] Step S2: determining a gear signal of an electronic gear shift controller according to the target gear information.

[0036] In an embodiment, the gear signal of the electronic shift controller is a gear signal used for state synchronization of the electronic shift controller when the transmission and the electronic shift controller are powered on and initialized. After the electronic shift controller is powered on and initialized, within a specified time after the transmission initialization is completed, when it verifies that the target gear information in the transmission target gear message signal is neutral, it determines that the gear signal of the electronic shift controller is neutral, and the electronic shift controller sends the neutral signal to the transmission as the gear signal for state synchronization between the transmission and the electronic shift controller.

[0037] It can be understood that the target gear information is not affected by the transmission power-off delay. For example, regardless of whether the transmission has a power-off delay, the transmission's target gear information is neutral. If the vehicle is powered off and the transmission has not entered sleep mode, the vehicle is quickly powered on again, and the transmission is not powered off successfully, the transmission's target gear information is neutral. During this period, the electronic shift controller successfully powers off and stops sending messages. After powering on again, the electronic shift controller receives the transmission's target gear information as neutral, then the electronic shift controller will send a neutral "handshake" signal. At this time, the status of the transmission and the electronic shift controller are successfully synchronized, and the handle fault will not be activated by mistake.

[0038] The current gear signal of the transmission is affected by the transmission power-off delay. For example, after the vehicle is powered off and the transmission has not entered the sleep period, the vehicle is quickly powered on again, and the transmission has not been powered off successfully. The current gear signal of the transmission is still a normal gear (such as P gear). During this period, the electronic shift controller is successfully powered off and stops sending messages. After powering on again, the electronic shift controller receives that the current gear of the transmission is a normal gear. In this case, the electronic shift controller will not send a neutral gear "handshake signal". At this time, the transmission will mistakenly activate the handle fault because it did not receive the "handshake signal" from the electronic shift controller.

[0039] Therefore, the target gear information of the transmission is used as the state synchronization signal for verifying the transmission and the electronic shift controller, instead of using the current gear signal of the transmission in the prior art as the state synchronization signal for verifying the transmission and the electronic shift controller. This avoids the problem that the transmission receives a non-neutral gear signal in the current gear signal when the transmission is powered on when it fails to power off due to power-off delay, resulting in failure of the state synchronization between the transmission and the electronic shift controller, i.e., "handshake", and activation handle failure.

[0040] In addition, after the vehicle triggers the transmission to enter neutral and coast during driving, if the electronic shift controller is restarted due to a line failure, the transmission and the electronic shift controller will also synchronize their status after startup, that is, "shake hands", to verify the gear position of the transmission. If the current gear position of the transmission in the prior art is used as a state synchronization signal to verify the transmission and the electronic shift controller, when coasting in neutral, the current gear position of the transmission is neutral. After verifying that the current gear position of the transmission is neutral, the electronic shift controller will mistakenly send a neutral signal. After receiving the neutral signal, the transmission will mistakenly take neutral as the target gear and shift gears by mistake, so that the vehicle is still in neutral after the neutral coasting ends, causing an emergency stop after the neutral coasting ends, etc., causing safety hazards and reducing the user's car experience and safety.

[0041] However, if the target gear position of the transmission is used as a status synchronization signal to verify the transmission and the electronic shift controller, the target gear position of the transmission will remain in D gear when coasting in neutral. After verifying that the current target gear position of the transmission is D gear, the electronic shift controller will not mistakenly send a neutral signal, and will not cause an emergency stop after the neutral coasting ends. This ensures the correctness of the gear position instructions sent by the electronic shift controller during driving, and improves the user's car experience and safety.

[0042] Step S3: Controlling the vehicle to start according to the gear position signal of the electronic shift controller.

[0043] In an embodiment, the electronic shift controller sends a neutral signal to the transmission as a gear signal for synchronizing the status of the transmission and the electronic shift controller. After the status of the transmission and the electronic shift controller are successfully synchronized, the subsequent process of controlling the start of the vehicle is entered to ensure the correct interaction between the transmission and the electronic shift controller. According to the signal control method of the transmission mechanism of the embodiment of the present invention, by obtaining the target gear information when the transmission is powered on and initialized, the gear signal of the electronic shift controller and the transmission state is determined with more stable target gear information, and the vehicle start is controlled according to the state synchronization result, so as to improve the stability and accuracy of the signal control of the transmission mechanism, ensure the correct interaction between the transmission and the electronic shift controller, and ensure the correctness of the gear instructions sent by the electronic shift controller during driving, thereby improving the user experience and safety of the vehicle.

[0044] In some embodiments, determining the gear signal of the electronic shift controller according to the target gear information includes: when the target gear signal is a preset gear signal, the electronic shift controller sends the preset gear signal to the transmission.

[0045] In an embodiment, the preset gear signal is a gear signal, i.e., a "handshake" signal, used for state synchronization of the gearbox and the electronic shift controller during power-on initialization. Since the gearbox is usually initialized to neutral as a safety reference during power-on initialization, the gearbox and the electronic shift controller can successfully synchronize their states when the preset gear signal is neutral. When the target gear signal is the preset gear signal, the electronic shift controller sends the preset gear signal to the gearbox. For example, after power-on initialization, the electronic shift controller verifies that the target gear signal in the gearbox target gear message signal is neutral within a specified time after the transmission initialization is completed. Then, the electronic shift controller sends the neutral signal to the gearbox as the gear signal for state synchronization.

[0046] It can be understood that the target gear signal is not affected by the transmission power-off delay. For example, regardless of whether the transmission has a power-off delay, the transmission's target gear signal is neutral. If the vehicle is powered off and the transmission has not entered sleep mode, the vehicle is quickly powered on again, and the transmission is not powered off successfully, the transmission's target gear signal is neutral. During this period, the electronic shift controller successfully powers off and stops sending messages. After powering on again, the electronic shift controller receives the transmission's target gear signal as neutral, then the electronic shift controller will send a neutral "handshake" signal. At this time, the status of the transmission and the electronic shift controller are successfully synchronized, and the handle fault will not be activated by mistake.

[0047] The current gear signal of the transmission is affected by the transmission power-off delay. For example, after the vehicle is powered off and the transmission has not entered the sleep period, the vehicle is quickly powered on again, and the transmission has not been powered off successfully. The current gear signal of the transmission is still a normal gear (such as P gear). During this period, the electronic shift controller is successfully powered off and stops sending messages. After powering on again, the electronic shift controller receives that the current gear of the transmission is a normal gear. In this case, the electronic shift controller will not send a neutral gear "handshake signal". At this time, the transmission will mistakenly activate the handle fault because it did not receive the "handshake signal" from the electronic shift controller.

[0048] Therefore, the target gear signal of the transmission is used as the state synchronization signal for verifying the transmission and the electronic shift controller, instead of using the current gear signal of the transmission in the prior art as the state synchronization signal for verifying the transmission and the electronic shift controller. This avoids the problem that the transmission receives a non-neutral gear signal in the current gear signal when the transmission is powered on when it is not successfully powered off due to power-off delay, resulting in failure of the state synchronization between the transmission and the electronic shift controller, i.e., "handshake", and activation handle failure.

[0049] In addition, after the vehicle triggers the transmission to enter neutral and coast during driving, if the electronic shift controller is restarted due to a line failure, the transmission and the electronic shift controller will also synchronize their status after startup, that is, "shake hands", to verify the gear position of the transmission. If the current gear position of the transmission in the prior art is used as a state synchronization signal to verify the transmission and the electronic shift controller, when coasting in neutral, the current gear position of the transmission is neutral. After verifying that the current gear position of the transmission is neutral, the electronic shift controller will mistakenly send a neutral signal. After receiving the neutral signal, the transmission will mistakenly take neutral as the target gear and shift gears by mistake, so that the vehicle is still in neutral after the neutral coasting ends, causing an emergency stop after the neutral coasting ends, etc., causing safety hazards and reducing the user's car experience and safety.

[0050] However, if the target gear position of the transmission is used as a status synchronization signal to verify the transmission and the electronic shift controller, the target gear position of the transmission will remain in D gear when coasting in neutral. After verifying that the current target gear position of the transmission is D gear, the electronic shift controller will not mistakenly send a neutral signal, and will not cause an emergency stop after the neutral coasting ends. This ensures the correctness of the gear position instructions sent by the electronic shift controller during driving, and improves the user's car experience and safety.

[0051] In some embodiments, determining the gear signal of the electronic shift controller according to the target gear information includes: when the target gear signal is not a preset gear signal, the electronic shift controller does not send the preset gear signal to the transmission.

[0052] In an embodiment, when the target gear position signal is not a preset gear position signal, the electronic shift controller does not send the preset gear position signal to the transmission. For example, after the electronic shift controller is powered on and initialized, within a specified time after the transmission initialization is completed, if the target gear position signal in the transmission target gear position message signal is not neutral, the electronic shift controller does not send the neutral signal to the transmission as a gear position signal for state synchronization, so as to ensure the correctness of the state verification between the electronic shift controller and the transmission during power-on and initialization.

[0053] In some embodiments, controlling vehicle startup according to a gear signal of an electronic shift controller includes: when the gear signal is a preset gear signal, determining that the electronic shift controller and the transmission have successfully shaken hands, and controlling the vehicle startup.

[0054] In an embodiment, when the gear signal is a preset gear signal, it is determined that the electronic shift controller and the transmission have successfully shaken hands, and the vehicle is controlled to start. For example, when the gear signal of the electronic shift controller is neutral, the electronic shift controller sends a neutral "handshake" signal, and the target gear signal of the transmission is also neutral. In this case, the electronic shift controller and the transmission have successfully shaken hands, and the subsequent process of controlling the vehicle to start can be entered to ensure the correct interaction between the transmission and the electronic shift controller.

[0055] In some embodiments, before obtaining the target gear information of the transmission, the method further includes: determining that the electronic shift controller is powered on.

[0056] In an embodiment, it is determined that the electronic shift controller is powered on. For example, a shift control unit or a vehicle controller on a vehicle determines that the electronic shift controller is powered on, so as to complete initialization after power-on.

[0059] Step S10: Determine whether the electronic shift controller is powered on.

[0060] Step S11, obtaining target gear information of the transmission.

[0061] Step S12: Determine whether the target gear signal is a preset gear signal. If so, execute step S14; otherwise, execute step S13.

[0062] In step S13, the electronic shift controller does not send a preset gear signal to the transmission.

[0063] Step S14: The electronic shift controller sends a preset gear signal to the transmission.

[0064] Step S15: Determine that the electronic shift controller and the transmission have successfully completed handshake, and control the vehicle to start.

[0065] According to an embodiment of the present invention, it is determined that the electronic shift controller and the transmission have successfully shaken hands, and the vehicle is controlled to start. By obtaining the target gear information when the transmission is powered on and initialized, the gear signal of the electronic shift controller and the transmission is determined with more stable target gear information. The vehicle is controlled to start according to the status synchronization result, so as to improve the stability and accuracy of the signal control of the speed change mechanism, ensure the correct interaction between the transmission and the electronic shift controller, and ensure the correctness of the gear instructions sent by the electronic shift controller during driving, thereby improving the user's car experience and car safety.
