It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of a shift reminding method according to an exemplary embodiment of the present application is shown, where the shift reminding method can be applied to a controller installed in a Vehicle, such as a Vehicle Control Unit (VCU). As shown in fig. 1, the method comprises the steps of:
s102, responding to a gear shifting request for the vehicle, acquiring the running state information of the vehicle.
Wherein the shift request is for requesting a shift of a gear of the vehicle from a current gear to a target gear.
The driving state information of the vehicle refers to information capable of representing the driving state of the vehicle, and may specifically include, but is not limited to, a driving speed, brake pedal state information, an operating mode, and charging information, wherein the brake pedal state information is used for indicating whether a brake pedal is pressed, and the charging information is used for reflecting the charging state of the vehicle.
In specific implementation, the driving state information of the vehicle may be collected through a driving monitoring device disposed on the vehicle, where the driving monitoring device may include, but is not limited to, a displacement sensor, a speed sensor, a charging management module, and other modules or sensors capable of monitoring the driving state information of the vehicle, the displacement sensor may monitor an opening degree of a brake pedal and identify whether the brake pedal is pressed based on the monitored opening degree, the speed sensor may monitor a driving speed of the vehicle, and the charging management module may monitor whether a charging wire of the vehicle is connected to an external charging device, and so on.
When a driver needs to shift gears, the driver can operate a gear shifter of the vehicle to shift gears, the gear shifter can identify current gear information of the vehicle and target gear information to which the driver wants to switch according to the operation of the driver, and accordingly a corresponding gear shifting request is generated and sent to a controller of the vehicle, wherein the gear shifting request carries the current gear information and the target gear information of the vehicle. The controller receives a gear shifting request from the gear shifter, responds to the gear shifting request, and acquires the driving state information of the vehicle, which is acquired by a driving monitoring device of the vehicle.
And S104, determining whether to execute the gear shifting operation corresponding to the gear shifting request or not based on the running state information of the vehicle and the gear shifting condition corresponding to the gear shifting request.
The gear shifting conditions are conditions required to be met by executing gear shifting operation, and the conditions required to be met by different gear shifting operations are different and can be specifically preset according to actual needs. In an optional embodiment, because the current gear information and the target gear information carried in the shift request can represent the shift operation requested to be executed by the shift request, based on this, in order to improve the efficiency and accuracy of executing the shift identification arbitration, a shift condition corresponding to the shift request can be determined, and whether the driving state information of the vehicle meets the shift condition is further detected, if so, the shift operation corresponding to the shift request is executed; otherwise, execution of the shift operation corresponding to the shift request is denied.
More specifically, the controller may previously store therein the correspondence between different shift operations indicating the initial gear and the target gear and the shift conditions. Further, after receiving the shift request, the corresponding relationship may be queried based on the current gear information and the target gear information carried in the shift request, so as to determine the shift condition corresponding to the shift request.
And S106, if not, outputting gear shifting prompt information corresponding to the gear shifting request based on the driving state information of the vehicle and the gear shifting condition corresponding to the gear shifting request, wherein the gear shifting prompt information is used for prompting the reason of the failure execution of the gear shifting operation.
When the gear shifting operation corresponding to the gear shifting request is refused to be executed, the information that the gear shifting condition is not met in the running state information is determined by analyzing the running state information and the gear shifting condition corresponding to the gear shifting request, the failure reason of the gear shifting operation is determined based on the information, and gear shifting prompt information used for prompting the failure reason of the gear shifting operation is further output, so that a driver can timely know the gear shifting failure reason, and corresponding improvement measures are taken to shift gears again. The form of the prompting message may include, but is not limited to, one or more of voice, text, light, and the like.
According to the gear shifting reminding method provided by the embodiment of the application, whether the gear shifting operation corresponding to the gear shifting request is executed or not is determined based on the driving state information of the vehicle and the gear shifting condition corresponding to the received gear shifting request, so that damage to a driver or the vehicle due to mistaken gear shifting or improper gear shifting operation can be avoided, and the safety of the vehicle is ensured; when the gear shifting operation corresponding to the gear shifting request is refused to be executed, the gear shifting prompt information corresponding to the gear shifting request is output based on the driving state of the vehicle and the gear shifting operation corresponding to the gear shifting request, so that a driver can timely know the gear shifting failure reason and take corresponding improvement measures, the effect of assisting the driver in gear shifting is achieved, the probability of gear shifting failure can be reduced, and the reliability of the gear shifting operation is improved.
In order to enable the driver to obtain more accurate gear shift failure reasons in time so as to further improve the reliability of the gear shift operation, in an optional implementation manner, when the driving state information of the vehicle does not meet the gear shift condition corresponding to the gear shift request, the failure reasons of the gear shift operation may be analyzed based on the difference between the driving state information and the gear shift condition, and gear shift prompt information corresponding to the gear shift request is further output.
Through analysis of a large amount of existing gear shifting operation information, the reasons for failure of gear shifting operation mainly include that the vehicle speed is over-limit, the vehicle is not in a driving state, the brake pedal is not pressed down, the connection with the external charging device is not disconnected, and the like, and accordingly, the gear shifting prompt information may include, but is not limited to, at least one of the following prompt information: the system comprises a first gear shifting prompt message used for prompting that the vehicle speed exceeds the limit, a second gear shifting prompt message used for prompting that the vehicle is not in a driving state, a third gear shifting prompt message used for prompting that a brake pedal is not stepped down, a fourth gear shifting prompt message used for prompting that the connection between the vehicle and external charging equipment is not disconnected, and the like.
Further, considering that the vehicle may be in different situations under different gear shifting operations, in order to ensure the safety of the vehicle under the situation of the gear shifting operation, the gear shifting condition corresponding to the gear shifting operation may be set according to the initial gear and the target gear indicated by the gear shifting operation, and accordingly, the reason causing the failure of the gear shifting operation may also be different.
Alternatively, when the shift position of the vehicle is switched from the forward gear (D gear) to the reverse gear (R gear) or from the reverse gear to the forward gear, that is, when the current shift position of the vehicle is the forward gear and the target shift position is the reverse gear, or when the current shift position of the vehicle is the reverse gear and the target shift position is the forward gear, since the shift operation usually occurs during the running of the vehicle, if the vehicle speed is too fast or the vehicle is not in a driving state and a shift is forced, a safety accident may be caused and damage may be caused to the driver or even the vehicle, and based on this, the shift condition corresponding to the shift operation may include: the running speed does not exceed a preset speed threshold value, and the working mode of the vehicle is a driving mode.
Accordingly, in the above S104, if the running speed of the vehicle does not exceed the preset speed threshold and the operating mode of the vehicle is the driving mode, a shift operation corresponding to the shift request is performed to switch the gear of the vehicle from the current gear to the target gear; if the running state information of the vehicle does not satisfy any of the above-described shift conditions, execution of a shift operation corresponding to the shift request is denied.
Correspondingly, in the step S106, if the running speed of the vehicle exceeds the preset speed threshold, the first gear shift prompting message is output to prompt the driver that the reason for the failed execution of the current gear shift operation is that the vehicle speed of the vehicle is over-limit; and if the working mode of the vehicle is a non-driving mode, outputting the second gear shifting prompt information to prompt the driver that the reason for the failure in executing the current gear shifting operation is that the vehicle is not in a driving state.
Alternatively, when the shift position of the vehicle is switched from the neutral position (i.e., N-range) to the reverse position or the forward position, i.e., the current shift position of the vehicle is the neutral position, and the target shift position is the reverse position or the forward position, considering that this process usually occurs when the vehicle starts or the driver mistakenly triggers the shift device, in this case, not only may the vehicle speed be too fast or the vehicle is not in a driving state, but also the forced shift may cause damage to the driver or the vehicle, and the driver may mistakenly trigger the shift device during driving, which may cause damage to the driver or the vehicle, the shift conditions corresponding to the above-mentioned shift operation may include: the running speed does not exceed a preset speed threshold value, the working mode is a driving mode, and the brake pedal is pressed down.
Accordingly, in the above S104, if the traveling speed of the vehicle does not exceed the preset speed threshold, the operation mode is the driving mode, and the brake pedal state information indicates that the brake pedal is depressed, a shift operation corresponding to the shift request is performed to switch the gear of the vehicle from the current gear to the target gear; if the running state information of the vehicle does not satisfy any of the above-described shift conditions, execution of a shift operation corresponding to the shift request is denied.
Accordingly, in the above S106, if the running speed of the vehicle exceeds the preset speed threshold, the first gear shift prompting message is output to prompt the driver that the reason for the failed execution of the current gear shift operation is that the vehicle speed of the vehicle is over-limit; if the working mode of the vehicle is a non-driving mode, outputting second gear shifting prompt information to prompt the driver that the reason for the failure in executing the current gear shifting operation is that the vehicle is not in a driving state; and if the running speed of the vehicle does not exceed the preset speed threshold value and the brake pedal state information of the vehicle indicates that the brake pedal of the vehicle is not pressed, outputting third gear shifting prompt information to prompt the driver that the reason for the failure in executing the current gear shifting operation is that the brake pedal of the vehicle is not pressed.
Alternatively, when the gear of the vehicle is switched from the parking gear (P gear) to the forward gear or the reverse gear, or is switched from the neutral state to the forward gear or the reverse gear, that is, the current gear of the vehicle is the forward gear or the gear error, and the target gear is the forward gear or the reverse gear, considering that this shift operation usually occurs during the vehicle starting process or the vehicle stopping process, in order to ensure that the vehicle can have a certain power and avoid the driver from mistakenly triggering the gear shifter and directly shifting gears when the charging is not completed to cause damage to the driver or the vehicle, the shift conditions corresponding to the shift operation may include: the charging request signal is not received, the brake pedal is pressed down and the working mode is the driving mode. The charging request signal is sent by the vehicle charging management module when the vehicle is detected to be connected to the external charging equipment, and if the charging request signal is not received, the vehicle can be determined not to be in a charging state, and the connection between the vehicle and the external charging equipment is disconnected.
Accordingly, in the above S104, if the controller does not receive the charging request signal, the acquired brake pedal state information indicates that the brake pedal is pressed, and the operating mode of the vehicle is the driving mode, the shift operation corresponding to the shift request is performed to switch the gear of the vehicle from the current gear to the target gear; if the running state information of the vehicle does not satisfy any of the above-described shift conditions, execution of a shift operation corresponding to the shift request is denied.
Accordingly, in the above S106, if the operating mode of the vehicle is the non-driving mode, the second gear shift prompting message is output to prompt the driver that the reason for the failed execution of the current gear shift operation is that the vehicle is not in the driving state;
if the brake pedal state information of the vehicle indicates that the brake pedal of the vehicle is not pressed, outputting the third gear shifting prompt information to prompt the driver that the reason for the execution failure of the current gear shifting operation is that the brake pedal of the vehicle is not pressed;
and if the charging information of the vehicle indicates that the charging request signal is received, outputting the fourth gear shifting prompt information to prompt the driver that the reason for the failure in executing the current gear shifting operation is that the connection between the vehicle and the external charging equipment is not disconnected.
Alternatively, when the gear of the vehicle is switched from the parking gear to the neutral gear, or is switched from the neutral gear state to the neutral gear state, that is, the current gear of the vehicle is the parking gear or the gear error, and the target gear is the neutral gear, considering that this gear shift operation usually occurs in the situations of vehicle starting, driver mistakenly triggering the gear shifter, etc., in order to avoid damage to the driver and the vehicle due to the mistaken gear shift, the safety of the vehicle starting stage is ensured, and the gear shift condition corresponding to the gear shift operation may include: the brake pedal is depressed and no charge request signal is received.
Accordingly, in the above S104, if the acquired brake pedal state information indicates that the brake pedal of the vehicle is stepped on and the charging request signal is not received, it may be determined that the received shift request is not caused by the driver' S false trigger and the currently executed shift operation is safe, and then the shift operation corresponding to the shift request may be executed; if the running state information of the vehicle does not satisfy any of the above-described shift conditions, execution of a shift operation corresponding to the shift request is denied.
Accordingly, in the above S106, if the brake pedal state information of the vehicle indicates that the brake pedal of the vehicle is not pressed, the above third gear shift prompting information is output to prompt the driver that the reason for the failure in executing the current gear shift operation is that the brake pedal of the vehicle is not pressed; and if the charging information of the vehicle indicates that the charging request signal is received, outputting the fourth gear shifting prompt information to prompt the driver that the reason for the failure in executing the current gear shifting operation is that the connection between the vehicle and the external charging equipment is not disconnected.
In order to ensure normal execution of the shift request, further, after the shift prompt information corresponding to the shift request is output, the shift prompt method provided in the embodiment of the present application may further include: and when the running state information of the vehicle is monitored to meet the gear shifting condition corresponding to the gear shifting request, stopping outputting the gear shifting prompt information and executing the gear shifting operation corresponding to the gear shifting request.
It should be noted that, a specific implementation manner of monitoring whether the driving state information of the vehicle satisfies the shift condition corresponding to the shift request is similar to the related implementation manner in S104, and specific reference may be made to the description of S104, which is not described herein again.
