Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example 1
The scheme provided by the embodiment of the application can be applied to any control system with motor control capability, such as a control module or equipment provided with a processing chip.
With the development of science and technology, vehicles are also widely used in life, which also puts higher demands on functions of the vehicles, and for this reason, more and more electric devices are gradually added to the vehicles to provide more comfort and safety for users, and the provision of these functions also makes more and more high-voltage electric equipment used on the vehicles, especially in recent years, with the environmental protection requirement, purely electric driven vehicles are appeared. In such an electric vehicle, since a motor is used as a driving means, there is an essential difference from a driving means used in a conventional gasoline vehicle. In particular, in electric vehicles, the transmission is no longer required for speed control, so that the processing of the gear signals in electric vehicles also differs considerably from conventional gasoline vehicles.
In particular, in vehicle control, shift control is an important part of whole vehicle running and ensuring safety, and therefore, strict and accurate state jump processing is required to implement the user's driving intention while ensuring the whole vehicle running safety. For example, a conventional gasoline vehicle can trigger a gear box to switch a corresponding gear combination by a user's operation of a gearshift device, and can confirm that the gear change has been completed in the case of switching to the gear combination corresponding to the gear. However, in the control of the electric vehicle, since the electric vehicle uses the motor as a driving means, it is not necessary to provide a plurality of gears for the control of the one-way speed as in the conventional gasoline vehicle, but the rotation speed of the motor and thus the rotation speed of the wheels driven by the motor can be controlled based only on the control of the magnitude of the current supplied to the motor.
For example, a driver of an electric vehicle may operate a gear shift device of the vehicle to initiate a gear shift command after starting the vehicle, which in this embodiment may be a user operating a gear shift device such as a gear shift lever out of a current gear, i.e. a position where the gear shift device is out of the current gear, at which time a gear signal processing scheme according to an embodiment of the present application may be triggered to execute to receive a gear shift signal issued by such an operation by the user, such that such a gear shift signal may indicate that the user wants to switch gears starting from the current gear. The gear information of the current gear before the user triggers the emission of the shift signal can be acquired. For example, the user may perform a shift operation when starting the vehicle, in which case the user operates the shift device while the current gear before the shift operation is triggered should be the park gear (i.e., P gear), and after the user triggers the shift operation, the shift device may leave the park gear, and may be in a stage where other gears have not been reached yet, that is, the user is in a state of moving from the current gear before the transmission of the shift signal to the other gears for a period of time after the shift signal is triggered. Therefore, in the embodiment of the present application, the completion time threshold may be set in advance for the shift operation, so that timing may be started after the shift signal is received and the gear information of the current gear before transmission of the shift signal is acquired, and it is determined whether additional gear information is received within a predetermined period of time from the reception of the shift signal. In the embodiment of the present application, in the case where the second gear information is detected within the set predetermined period of time, it may be considered that the user has completed the shift operation, and the time when the second gear information is received may be further calculated, and whether or not there is an error in the shift operation performed by the user may be determined based on the time, so that the shift operation may be performed according to the current gear information and the time and the final gear information. For example, if the current gear before the user triggers the shift signal is the park gear and the reverse gear is detected within a predetermined period of time, the time from the user performing the operation to the detection of the reverse gear may be further calculated from the detected reverse gear, and if the time is indeed less than a threshold set in advance, the shift operation may be considered to be effective. And the current gear before the user triggers the shift signal is the forward gear, it is necessary to confirm whether the motor has been in a stalled or low-rotation state for the time when the user performs the shift operation even if the reverse gear is detected as the second gear within a predetermined period of time. For example, in the embodiment of the present application, when the gear information of the second gear is acquired, the current state of the motor may be further acquired, so that the gear shifting process may be further performed according to the current state of the motor.
For example, when the current gear is a parking gear, the user moves the gear away from the parking gear by operating the shift device, and the user's shift is aimed at executing a reverse gear, so that the user can operate the shift device to change to the reverse gear. In this case, since the reverse gear is required at the rotation speed of the motor being zero or at least lower than 20 rotations, it is possible to further acquire the state of the motor upon receiving the user's operation of the gear shift device into the reverse gear, and to confirm whether the state of the motor is the first state in which the rotation speed required for entering the reverse gear is zero or at least lower than 20 rotations, for example. For example, in the case where the first state of the vehicle before the user operates the shift device is the parking gear, the motor rotation speed of the vehicle is zero, and when the first state where the rotation speed is zero is acquired, it can be confirmed that the current state of the motor meets the requirement of executing the shift to the reverse gear, and therefore, the shift operation from the parking gear to the reverse gear can be executed. In addition, in the case where the first state of the vehicle before the user operates the shift device is the forward gear, since the vehicle is in a state in which the drive motor is rotated forward in a state of the forward gear, and when the user wants to perform reverse gear in a state in which the drive motor is rotated forward, the vehicle may be braked first, for example, a braking instruction may be given by stepping on the brake pedal or by releasing the accelerator pedal in the single pedal mode, and the control module of the vehicle may cut off the power supply to the motor according to the braking instruction and may switch it to the braking mode, or may forward the power mode, to rotate the motor by the wheel rotation to convert the rotational kinetic energy into electric energy, to brake the rotation of the wheel during the energy conversion, and thereby reduce the rotational speed of the motor. Therefore, the reduction of the rotation speed of the motor can be achieved in both the braking mode and the forward power mode, so that when the micro signal processing scheme according to the embodiment of the application can receive the gear information of the user switching to the reverse gear, the acquired rotation speed state of the motor may not reach the rotation speed required by the reverse gear, and therefore, in the embodiment of the application, waiting for a predetermined time can be performed when the rotation speed of the motor according to the acquired rotation speed does not reach the rotation speed required by the reverse gear, so that the state information of the motor can be continuously acquired in the waiting period to continuously confirm whether the state of the motor reaches the required state, and when the required rotation speed state is reached, the gear switching process is immediately performed, so that the user can perform reverse on the vehicle. Further, if the state of the motor does not always reach the required rotation speed state within the predetermined waiting period, the gear information processing scheme according to the embodiment of the present application may generate alarm information to prompt the user, and may return the gear to the current gear of the user before performing the shift operation in this state, so that it is possible to avoid switching to the reverse state with the motor still maintained at the high rotation speed, resulting in damage to the motor.
Of course, under the condition that the motor state does not reach the rotating speed required by the reverse gear all the time in the preset waiting time period, the gear can be switched to the neutral gear, a processing scheme can be generated according to the current state of the motor, and the processing scheme is prompted to a user, so that the user can conveniently and timely perform the deceleration processing on the motor state.
According to the gear signal processing scheme, the gear information indicating the intention of gear switching is received, the gear information of the current gear before the gear switching signal is sent is obtained, then whether the second gear signal is received in the first time period from the time of receiving the gear signal is judged, and the second time period for receiving the second gear information is calculated when the second gear information is judged to be received, so that gear switching processing can be executed based on the first gear information, the second time period and the second gear information, and therefore comprehensive processing can be further carried out based on the gear information and the interval time, gear switching conditions of electric vehicles taking a motor as a driving mode are better adapted, and more accurate and more efficient gear switching processing is realized.
The foregoing embodiments are illustrative of the technical principles and exemplary application frameworks of the embodiments of the present application, and the detailed description of specific technical solutions of the embodiments of the present application will be further described below by means of a plurality of embodiments.
Example two
Fig. 1 is a flowchart of an embodiment of a gear signal processing method provided in the present application, where an execution body of the method may be various terminals or devices with signal processing capabilities, or may be devices or chips integrated on these devices. As shown in fig. 1, the gear signal processing method includes the following steps:
s101, receiving a gear shifting signal.
In step S101, a shift signal, which in the present embodiment may be a signal triggered by a user operating a shift device, such as a gear lever or a gear wheel, to move out of a current gear, may be received by a vehicle control module, such as a VCU. For example, a driver of an electric vehicle may operate a gear shift device of the vehicle to initiate a gear shift command after starting the vehicle, which in this embodiment may be a user operating a gear shift device such as a gear shift lever out of a current gear, i.e. a position where the gear shift device is out of the current gear, at which time a gear signal processing scheme according to an embodiment of the present application may be triggered to execute to receive a gear shift signal issued by such an operation by the user, such that such a gear shift signal may indicate that the user wants to switch gears starting from the current gear.
S102, first gear information of a first gear is acquired.
In step S102, gear information of a gear before the user operates the shift device to trigger the shift signal may be acquired. For example, the user may perform a shift operation when starting the vehicle, in which case the user operates the shift device while the current gear before the shift operation is triggered should be the park gear (i.e., P gear), and after the user triggers the shift operation, the shift device may leave the park gear, and may be in a stage where other gears have not been reached yet, that is, the user is in a state of moving from the current gear before the transmission of the shift signal to the other gears for a period of time after the shift signal is triggered. Or, after the user first performs the reverse operation and then wants to change to forward running, in step S101, after the user triggers the received shift signal by moving the gear lever or the gear shift wheel away from the reverse gear, in step S102, the reverse gear may be acquired as the first gear information.
S103, judging whether the second gear information is received in a first time period from the moment of receiving the gear shifting signal.
In step S103, it may be determined whether the second gear information is received within a predetermined period of time from the reception of the shift signal in step S101. For example, in the embodiment of the present application, the predetermined period of time may be set according to a general usage specification of the vehicle or according to a shift habit of a user, or may be set according to specifications or performance information of a shift-related component of the vehicle.
And S104, when the second gear information is received in the first time period, calculating a second time period from the time when the gear shifting signal is received to the time when the second gear information is received.
S105, performing gear shifting according to the first gear information, the second time period and the second gear information.
In step S104, it may be checked with the timing processing in step S103 whether or not the gear information of the second gear other than the first gear can be acquired, in this embodiment, the gear information of the gear may be transmitted by contact of a preset trigger member in the shift device with the corresponding gear, and may be received by a vehicle control module such as VCU, so that the second period of time from when the shift signal triggered by the shift operation of the user is received in step S101 to when the gear information of the new gear to which the user shifts the shift device is received in step S104 may be further calculated, and thus, the shift processing may be performed according to the second period of time and the first gear information and the second gear information before and after the shift.
Further, the current gear before the user triggers the shift signal is the park gear, and the reverse gear is detected within a predetermined period of time, then the time from the user performing the operation to the detection of the reverse gear may be further calculated from the detected reverse gear, and if the time is indeed less than a threshold value set in advance, the shift operation may be considered to be effective. And the current gear before the user triggers the shift signal is the forward gear, it is necessary to confirm whether the motor has been in a stalled or low-rotation state for the time when the user performs the shift operation even if the reverse gear is detected as the second gear within a predetermined period of time. For example, in the embodiment of the present application, when the gear information of the second gear is acquired, the current state of the motor may be further acquired, so that the gear shifting process may be further performed according to the current state of the motor.
For example, when the current gear is a parking gear, the user moves the gear away from the parking gear by operating the shift device, and the user's shift is aimed at executing a reverse gear, so that the user can operate the shift device to change to the reverse gear. In this case, since the reverse gear is required at the rotation speed of the motor being zero or at least lower than 20 rotations, it is possible to further acquire the state of the motor upon receiving the user's operation of the gear shift device into the reverse gear, and to confirm whether the state of the motor is the first state in which the rotation speed required for entering the reverse gear is zero or at least lower than 20 rotations, for example. For example, in the case where the first state of the vehicle before the user operates the shift device is the parking gear, the motor rotation speed of the vehicle is zero, and when the first state where the rotation speed is zero is acquired, it can be confirmed that the current state of the motor meets the requirement of executing the shift to the reverse gear, and therefore, the shift operation from the parking gear to the reverse gear can be executed. In addition, in the case where the first state of the vehicle before the user operates the shift device is the forward gear, since the vehicle is in a state in which the drive motor is rotated forward in a state of the forward gear, and when the user wants to perform reverse gear in a state in which the drive motor is rotated forward, the vehicle may be braked first, for example, a braking instruction may be given by stepping on the brake pedal or by releasing the accelerator pedal in the single pedal mode, and the control module of the vehicle may cut off the power supply to the motor according to the braking instruction and may switch it to the braking mode, or may forward the power mode, to rotate the motor by the wheel rotation to convert the rotational kinetic energy into electric energy, to brake the rotation of the wheel during the energy conversion, and thereby reduce the rotational speed of the motor.
Therefore, the reduction of the rotation speed of the motor can be achieved in both the braking mode and the forward power mode, so that when the micro signal processing scheme according to the embodiment of the application can receive the gear information of the user switching to the reverse gear, the acquired rotation speed state of the motor may not reach the rotation speed required by the reverse gear, and therefore, in the embodiment of the application, waiting for a predetermined time can be performed when the rotation speed of the motor according to the acquired rotation speed does not reach the rotation speed required by the reverse gear, so that the state information of the motor can be continuously acquired in the waiting period to continuously confirm whether the state of the motor reaches the required state, and when the required rotation speed state is reached, the gear switching process is immediately performed, so that the user can perform reverse on the vehicle. Further, if the state of the motor does not always reach the required rotation speed state within the predetermined waiting period, the gear information processing scheme according to the embodiment of the present application may generate alarm information to prompt the user, and may return the gear to the current gear of the user before performing the shift operation in this state, so that it is possible to avoid switching to the reverse state with the motor still maintained at the high rotation speed, resulting in damage to the motor.
Of course, under the condition that the motor state does not reach the rotating speed required by the reverse gear all the time in the preset waiting time period, the gear can be switched to the neutral gear, a processing scheme can be generated according to the current state of the motor, and the processing scheme is prompted to a user, so that the user can conveniently and timely perform the deceleration processing on the motor state.
According to the gear signal processing method, the gear information of the current gear before the gear is sent is obtained by receiving the gear shifting signal indicating the intention of gear switching, then whether the second gear signal is received in the first time period from the time of receiving the gear shifting signal is judged, and the second time period for receiving the second gear information is calculated when the second gear information is judged to be received, so that gear shifting processing can be executed based on the first gear information, the second time period and the second gear information, comprehensive processing can be further carried out based on the gear information and the interval time, gear shifting conditions of an electric vehicle taking a motor as a driving mode are better adapted, and more accurate and more efficient gear shifting processing is realized.
Example III
Fig. 2 is a schematic structural diagram of an embodiment of a gear signal processing device provided in the present application, which may be used to perform the method steps shown in fig. 1. As shown in fig. 2, the gear signal processing device may include: the device comprises a receiving module 21, an acquiring module 22, a judging module 23, a calculating module 24 and an executing module 25.
The receiving module 21 may be used to receive a shift signal.
The receiving module 21 may be a receiving module in a vehicle control module, such as a VCU, and may be used to receive a shift signal, which in this embodiment may be a user operated shift device, such as a gear lever or a gear
The shift wheel shifts out the triggered signal from the current gear. For example, after starting the vehicle, the driver of the electric vehicle may 5 operate the gear shifting device of the vehicle to initiate a gear shifting instruction, which in the embodiment of the present application may be a user operating the gear shifting device, such as a gear shift lever, out of the current gear, i.e. out of position of the current gear, at which time the gear signal processing scheme according to the embodiment of the present application may be triggered to be executed to receive a gear shifting signal issued by such an operation by the user, such that such a gear shifting signal may indicate that the user wants to switch gears starting from the current gear.
The acquisition module 22 may be configured to acquire first gear information for a first gear.
The 0 acquisition module 22 may acquire gear information for a gear prior to a user operating the shift device to trigger a shift signal.
For example, the user may perform a shift operation when starting the vehicle, in which case the user operates the shift device such that the current gear before the shift operation is triggered should be the park gear (i.e., P gear), and after the user triggers the shift operation, the shift device leaves the park gear and may be in a stage where other gears have not been reached, that is, the user is in a stage where
The shifting device is in a state of being moved from the current gear to 5 other gears before the transmission of the shift signal for a period of time after the shift signal is triggered. Or after the user performs the reversing operation, the user wants to change to forward running,
the acquisition module 22 may acquire the reverse gear as the first gear information after the receiving module 21 receives the shift signal that the user has triggered to receive by moving the shift lever or the shift wheel away from the reverse gear.
The determination module 23 may be configured to determine whether the second gear information is received within a first period of time from the time the shift signal is received.
The 0 determination module 23 may determine whether the second gear information is received within a predetermined period of time from when the reception module 21 receives the shift signal. For example, in the embodiment of the present application, the predetermined period of time may be set according to a general usage specification of the vehicle or according to a shift habit of a user, or may be set according to specifications or performance information of a shift-related component of the vehicle.
The calculation module 24 may be configured to calculate a second time period from receipt of the 5 shift signal to receipt of the second gear information when the second gear information is received within the first time period.
The execution module 25 may be configured to execute a shift process according to the first gear information, the second period of time, and the second gear information.
The calculation module 24 may check whether or not the gear information of the second gear other than the first gear can be acquired along with the timing process in the judgment module 23, in the present embodiment, the gear information of the gear may be transmitted through the contact of the preset touch 0 transmitting part in the shift device with the corresponding gear, and may be received by the calculation module 24 in the vehicle control module, for example, the VCU, so that the second period of time from when the reception module 21 receives the shift signal triggered by the shift operation of the user to when the calculation module 24 receives the gear information of the new gear to which the user shifts the shift device may be further calculated, and thus, the shift process may be performed according to the second period of time and the first gear information and the second gear information before and after the shift.
Further, the current gear before the user triggers the shift signal is the park gear, and the reverse gear is detected within a predetermined period of time, then the time from the user performing the operation to the detection of the reverse gear may be further calculated from the detected reverse gear, and if the time is indeed less than a threshold value set in advance, the shift operation may be considered to be effective. And the current gear before the user triggers the shift signal is the forward gear, it is necessary to confirm whether the motor has been in a stalled or low-rotation state for the time when the user performs the shift operation even if the reverse gear is detected as the second gear within a predetermined period of time. For example, in the embodiment of the present application, when the gear information of the second gear is acquired, the current state of the motor may be further acquired, so that the gear shifting process may be further performed according to the current state of the motor.
For example, when the current gear is a parking gear, the user moves the gear away from the parking gear by operating the shift device, and the user's shift is aimed at executing a reverse gear, so that the user can operate the shift device to change to the reverse gear. In this case, since the reverse gear is required at the rotation speed of the motor being zero or at least lower than 20 rotations, it is possible to further acquire the state of the motor upon receiving the user's operation of the gear shift device into the reverse gear, and to confirm whether the state of the motor is the first state in which the rotation speed required for entering the reverse gear is zero or at least lower than 20 rotations, for example. For example, in the case where the first state of the vehicle before the user operates the shift device is the parking gear, the motor rotation speed of the vehicle is zero, and when the first state where the rotation speed is zero is acquired, it can be confirmed that the current state of the motor meets the requirement of executing the shift to the reverse gear, and therefore, the shift operation from the parking gear to the reverse gear can be executed. In addition, in the case where the first state of the vehicle before the user operates the shift device is the forward gear, since the vehicle is in a state in which the drive motor is rotated forward in a state of the forward gear, and when the user wants to perform reverse gear in a state in which the drive motor is rotated forward, the vehicle may be braked first, for example, a braking instruction may be given by stepping on the brake pedal or by releasing the accelerator pedal in the single pedal mode, and the control module of the vehicle may cut off the power supply to the motor according to the braking instruction and may switch it to the braking mode, or may forward the power mode, to rotate the motor by the wheel rotation to convert the rotational kinetic energy into electric energy, to brake the rotation of the wheel during the energy conversion, and thereby reduce the rotational speed of the motor.
Therefore, the reduction of the rotation speed of the motor can be achieved in both the braking mode and the forward power mode, so that when the micro signal processing scheme according to the embodiment of the application can receive the gear information of the user switching to the reverse gear, the acquired rotation speed state of the motor may not reach the rotation speed required by the reverse gear, and therefore, in the embodiment of the application, waiting for a predetermined time can be performed when the rotation speed of the motor according to the acquired rotation speed does not reach the rotation speed required by the reverse gear, so that the state information of the motor can be continuously acquired in the waiting period to continuously confirm whether the state of the motor reaches the required state, and when the required rotation speed state is reached, the gear switching process is immediately performed, so that the user can perform reverse on the vehicle. Further, if the state of the motor does not always reach the required rotation speed state within the predetermined waiting period, the gear information processing scheme according to the embodiment of the present application may generate alarm information to prompt the user, and may return the gear to the current gear of the user before performing the shift operation in this state, so that it is possible to avoid switching to the reverse state with the motor still maintained at the high rotation speed, resulting in damage to the motor.
Of course, under the condition that the motor state does not reach the rotating speed required by the reverse gear all the time in the preset waiting time period, the gear can be switched to the neutral gear, a processing scheme can be generated according to the current state of the motor, and the processing scheme is prompted to a user, so that the user can conveniently and timely perform the deceleration processing on the motor state.
The gear signal processing device provided by the embodiment of the application, by receiving the 5-gear shift signal indicating the intention to perform gear shift and acquiring the gear information of the current gear before the gear shift signal is sent, then judging whether the second gear signal is received in the first time period from the time of receiving the gear shift signal, and calculating the second time period for receiving the second gear information when judging that the second gear information is received, the gear shift processing can be performed based on the first gear information, the second time period and the second gear information, and therefore, the comprehensive processing can be further performed based on the gear information and the interval time
The combination processing is performed, so that the gear shifting situation of the electric vehicle adopting the motor as a driving mode is better adapted, and the gear shifting processing with accuracy and high efficiency is realized.
