Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a vehicle gear shift prompting method, device, vehicle terminal, and storage medium. Background Technology

[0002] With the development of electric and intelligent vehicles, the use of column shifters for gear shifting has become the mainstream gear shifting mode in automobiles.

[0003] In existing technology, to prevent gear shifting failure due to the driver not pressing the brake pedal during gear shifting, a prompt is usually set to remind the driver to "press the brake before shifting" when the brake pedal is detected to be released during the shifting process. However, for column-mounted gearboxes, the brake pedal only needs to be pressed when starting to shift gears, and does not need to be pressed throughout the entire shifting process. Therefore, if the brake pedal is released normally during the shifting process, an incorrect prompt will be issued, affecting the driver's correct judgment and reducing the driving experience. Summary of the Invention

[0004] This invention provides a vehicle gear shifting reminder method, device, vehicle terminal, and storage medium to solve the problem in the prior art where the gear shifting reminder without braking will issue an incorrect prompt, affecting the driver's normal judgment.

[0007] When the first signal is detected to switch to the first preset value, the second signal is switched to the third preset value; when the shift is detected to end or the shift lever is detected to start shifting, the second signal is switched to the fourth preset value.

[0008] When the first signal is detected to be the second preset value, the second signal is detected to be the fourth preset value, and the gear lever is not in the initial position, a gear shift prompt is issued;

[0009] The shift indicator is used to remind users that the brake was not applied when shifting gears.

[0010] Optionally, when the first signal is detected to switch to a first preset value, the second signal switches to a third preset value, including:

[0013] Optionally, when the end of a gear shift is detected, or when the gear lever is detected to begin shifting, the second signal is switched to a fourth preset value, including:

[0014] When the shift ends or the shift lever begins to shift, the latch is reset. After the reset, the second signal output by the latch is switched to the fourth preset value.

[0015] Optionally, detecting that the gear lever has started shifting includes:

[0016] When the position of the gear lever is detected to have changed from its initial position to another position, the gear lever is determined to start shifting gears.

[0017] Optionally, detecting that the gear lever has started shifting includes:

[0018] When the rising edge signal of the column shifter is detected, it is determined that the shift lever has started to shift gears.

[0019] Optionally, when the gear lever is detected to begin shifting gears and the brake pedal is depressed, the first signal switches to a first preset value, including:

[0020] Obtain the brake pedal signal; wherein, if the brake pedal is depressed, the brake pedal signal is the first pedal signal; if the brake pedal is not depressed, the brake pedal signal is the second pedal signal.

[0021] If the rising edge signal of the shift lever is detected, and the brake pedal signal is the first pedal signal, then the first signal is switched to the first preset value.

[0022] Optionally, if the brake pedal signal is the first pedal signal when the rising edge of the shift lever is detected, the first signal is switched to a first preset value, including:

[0023] If the brake pedal signal is the first pedal signal when the rising edge signal of the gear shift is detected, and the brake pedal signal is the first pedal signal during a preset period before the rising edge signal of the gear shift is detected, then the first signal is switched to the first preset value.

[0024] Secondly, embodiments of the present invention provide a vehicle gear shift indicator device, comprising:

[0025] The first signal generation module is used to switch the first signal to a first preset value when it detects that the gear lever has started to shift gears and the brake pedal has been pressed; and to switch the first signal to a second preset value when it detects that the brake pedal has returned to the unpressed state or the gear lever has returned to the initial position.

[0026] The second signal generation module is used to switch the second signal to a third preset value when the first signal is detected to switch to a first preset value; and to switch the second signal to a fourth preset value when the shift is detected to end or the shift lever is detected to start shifting.

[0038] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, specific embodiments will be described below in conjunction with the accompanying drawings.

[0040] There are two types of gear shift levers in cars: floor shift and column shift. A column shifter is located to the lower right of the steering wheel. Column shifters are convenient and safe to operate, allowing the hands to remain on the steering wheel, and they save space, making more usable between the two front seats. They are becoming increasingly widely used.

[0041] Unlike floor-mounted gears, column-mounted vehicles do not require the brake pedal to be pressed for the entire time during gear shifting; the pedal only needs to be pressed at the start of the shift. Therefore, with the existing shift indication technology, when a column-mounted vehicle releases the pedal normally during the shifting process, it will issue an incorrect "shifting without braking" risk warning, causing unnecessary misunderstanding for the driver and affecting the driver's judgment.

[0042] Based on this, embodiments of the present invention provide a vehicle gear shift prompt method, see [link to relevant documentation]. Figure 1 The diagram illustrates a flowchart of the vehicle gear shift prompting method provided in this embodiment of the invention. The method is applied to vehicles with column shifters, and the executing entity of the vehicle gear shift prompting method can be an on-board terminal. Specifically, the on-board terminal can be a vehicle controller, such as a PDCU (Powertrain Domain Control Unit) or VCU (Vehicle Control Unit), or other terminals within the vehicle capable of prompting gear shifts; no limitation is made here.

[0043] The above methods include:

[0044] S101: When it is detected that the gear lever has started to shift gears and the brake pedal has been pressed, the first signal is switched to the first preset value; when it is detected that the brake pedal has returned to the unpressed state, or the gear lever has returned to the initial position, the first signal is switched to the second preset value.

[0045] For vehicles with column shifters, shifting gears can be completed simply by pressing the brake pedal when shifting gears.

[0046] refer to Figure 2 For column shifters, the middle position is N (Neutral), and shifting up or down corresponds to D (Drive) or R (Reverse). When a column shifter vehicle is engaged in D / R while driving, it will automatically return to the middle position (defined as the initial position). Therefore, under normal circumstances, the shift lever has only two states: starting to shift gears (the shift lever position changes from the initial position to another position) or the shift lever returning to its initial position.

[0047] Based on this, in this embodiment of the invention, when the gear lever is detected to be shifting and the brake pedal is depressed, it indicates that the shift can be completed, and at this time, the first signal is set to a first preset value. If the above two conditions cannot be met simultaneously (the brake pedal returns to the undepressed state, or the gear lever returns to the initial position), the first signal is set to a second preset value, indicating that the shift conditions are not met and the shift cannot be completed.

[0048] In one possible implementation, detecting that the gear lever has started to shift gears may include: determining that the gear lever has started to shift gears when the position of the gear lever is detected to have changed from the initial position to another position.

[0049] When the position of the gear lever is detected to have changed from its initial position to another position, the gear lever is determined to start shifting gears.

[0050] In another possible implementation, detecting that the gear lever has started to shift gears may include determining that the gear lever has started to shift gears when the rising edge signal of the column shifter is detected.

[0051] When the gear lever is moved, a rising edge is generated in the gear lever signal, and a falling edge is generated when the gear lever is reset. Therefore, it can be used to determine whether the gear lever has started to shift gears.

[0052] For example, refer to Figure 3 When the brake pedal is depressed, the brake pedal signal is high; when the brake pedal returns to its undepressed state, the brake pedal signal is low. When the brake pedal signal is high at the rising edge of the gear lever signal, the first signal is set to the first preset value (high level). In all other cases, the first signal is the second preset value (low level). For example, when the brake pedal is released, the brake pedal signal drops to low, and the first signal switches to the second preset value (low level). As another example, when the brake pedal is depressed but the gear lever returns to its original position, the first signal is also the second preset value. Based on different vehicle states, the first signal switches between the first and second preset values.

[0053] The brake pedal state includes both depressed and undepressed states, which can be determined by pedal opening or pedal pressure. For example, when the pedal opening is less than a preset angle, it is defined as the pedal not being depressed; when the pedal opening is not less than the preset angle, it is defined as the pedal being depressed. Alternatively, the brake pedal state can be determined based on pedal pressure.

[0054] Specifically, the brake pedal opening signal is a signal in the vehicle's braking system that indicates the pressure or pedal opening applied by the driver on the brake pedal. When the driver presses the brake pedal, the vehicle's braking system detects the brake pedal opening through sensors and transmits the signal to the vehicle's ECU. Therefore, in this embodiment of the invention, the brake pedal opening signal can be directly acquired, and the determination of whether the pedal has been pressed can be based on the brake pedal opening signal.

[0055] S102: When the first signal is detected to switch to the first preset value, the second signal is switched to the third preset value; when the shift is detected to end or the shift lever is detected to start shifting, the second signal is switched to the fourth preset value.

[0056] When the first signal is detected to switch to the first preset value, the second signal is set to the third preset value to indicate that the vehicle may be in the current shift process. When the shift ends or the gear lever is detected to start shifting again, it means that the vehicle is about to or is entering the next shift process and is ready to shift, so the second signal is set to the fourth preset value.

[0057] For example, if the gear lever is not reset after being moved to the target gear due to the driver's hand blocking it, but the actual gear shift has been completed, then a second gear shift can be initiated; or, for another example, if the gear lever is reset and then detected to be shifting again, it indicates that a second gear shift is being initiated.

[0058] It should be noted that detecting the end of gear shift means detecting the end of the actual gear shifting process of the vehicle, that is, the vehicle's gear has been switched, not that the gear lever has been switched.

[0059] In this embodiment of the invention, when the first signal is detected to switch to the first preset value, the second signal is switched to the third preset value and remains at the third preset value until the end of the shift is detected or the shift lever is detected to start shifting. This is equivalent to latching the switching state of the first signal, while the end of the shift or the shift lever is detected to start shifting is equivalent to a reset condition.

[0060] Based on the above, in one possible implementation, S102 may include:

[0061] S1021: Input the first signal into the latch, and the latch outputs the second signal;

[0062] When the first signal switches to the first preset value, it is latched by the latch, and the second signal output by the latch switches to the third preset value.

[0063] In one possible implementation, S102 may include:

[0064] S1022: When the end of gear shift is detected or the gear lever is detected to start shifting, the latch is reset. After the reset, the second signal output by the latch is switched to the fourth preset value.

[0065] In this embodiment of the invention, a latch is used to latch the state of the first signal, and the end of shifting or the start of shifting is used as a reset condition to reset, thereby realizing the latching and reset of the state of the first signal by the second signal.

[0066] In one possible implementation, the first preset value is 1, the second preset value is 0, the third preset value is 1, and the fourth preset value is 0.

[0067] That is, when the brake pedal is pressed when the gear lever is detected to start shifting gears, the first signal is 1; otherwise, it is 0.

[0068] When the first signal switches from 0 to 1, the second signal latches and outputs 1, and is reset when the shift ends or the gear lever starts shifting, at which point the second signal resets and outputs 0.

[0069] It should be noted that the first to fourth preset values ​​can be set according to actual application needs and are not limited to the values ​​mentioned above.

[0070] S103: When the first signal is detected to be the second preset value, the second signal is detected to be the fourth preset value, and the gear lever is not in the initial position, a gear shift prompt is issued;

[0071] The shift indicator is used to remind users that the brake was not applied when shifting gears.

[0072] In this embodiment of the invention, when the first signal is the second preset value, it indicates that the shifting conditions are not met; when the second signal is the fourth preset value, it indicates that the vehicle is about to enter the next shifting process. If the gear is not in the initial position at this time, it indicates that the vehicle is shifting gears and the brake is not applied. A shifting prompt is issued to prompt the driver to apply the brake.

[0073] When shifting from neutral (N) to other gears without applying the brakes, the first signal is the second preset value because the brakes are not applied. Simultaneously, the gear lever has been reset from the previous shift, so the second signal is the fourth preset value. Since the gear lever is not in its initial position, a correct shift prompt is issued.

[0074] For gear shifts without applying the brakes when shifting from neutral (N) to other gears, the first signal is the second preset value because the brakes are not applied. Although the gear lever is not reset, the shift is completed, and the second signal is the fourth preset value. Even though the gear lever is not in its initial position, the correct shift prompt can still be issued.

[0075] Based on the above, it is difficult to define gear shifts that do not involve switching from neutral (N) to other gears. Therefore, it is impossible to directly judge based on the gear lever position and brake pedal status. In this embodiment of the invention, the second signal is generated based on the first signal. Combining the first and second signals can simultaneously and accurately prompt the driver about the situation where the brake is not applied during the above two gear shifting processes. This effectively improves the accuracy of the prompts, avoids misleading the driver with incorrect prompts, and enhances the driving experience and vehicle intelligence.

[0076] In one possible implementation, S101 may include:

[0077] S1011: Obtain the brake pedal signal; wherein, if the brake pedal is depressed, the brake pedal signal is the first pedal signal; if the brake pedal is not depressed, the brake pedal signal is the second pedal signal.

[0078] S1012: If the rising edge signal of the column shifter is detected and the brake pedal signal is the first pedal signal, then the first signal is switched to the first preset value.

[0079] In this embodiment of the invention, a brake pedal signal is generated based on whether the brake pedal is depressed. When the shift lever rises, the brake pedal signal is the first pedal signal. When both conditions are met, the first signal is switched to the first preset value.

[0080] In one possible implementation, S1012 may include: if the brake pedal signal is the first pedal signal when the rising edge signal of the gear shift is detected, and the brake pedal signal is the first pedal signal during a preset period before the rising edge signal of the gear shift is detected, then the first signal is switched to the first preset value.

[0081] For safety reasons, it is usually necessary to depress the brake pedal before shifting gears to complete a safe and stable gear shift. Therefore, this embodiment of the invention requires that the brake pedal signal be the first pedal signal before the column shifter rise edge signal is detected, before switching the first signal to the first preset value, thus ensuring the safety and stability of gear shifting.

[0082] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0086] The second signal generation module 22 is used to switch the second signal to a third preset value when the first signal is detected to switch to a first preset value; and to switch the second signal to a fourth preset value when the shift is detected to end or the shift lever is detected to start shifting.
