Detailed Description
To further clarify the above and other features and advantages of the present application, a further description of the application will be rendered by reference to the appended drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not limiting, as to those skilled in the art.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the specific details need not be employed to practice the present application. In other instances, well-known steps or operations have not been described in detail in order to avoid obscuring the application.
The gear control method of the vehicle provided by the embodiment of the application can be executed by the gear control device of the vehicle provided by the embodiment of the application, and the device can be configured in electronic equipment.
Referring to fig. 1, the application provides a gear control method of a vehicle, which is applied to a vehicle control unit VCU, and includes:
step 101, determining a first target gear according to the driver gear shifting operation information and the vehicle state information.
The shift operation information of the driver may be a control instruction received by the vehicle controller when the driver wants to switch the gear of the vehicle, where the control instruction may be a trigger operation performed by the driver on a control, a button, an operation lever, etc. in the vehicle, or may be shift operation information determined by the vehicle controller based on current state information of the vehicle, etc. the present application is not limited thereto.
The vehicle state information may be the vehicle speed, whether the accelerator pedal is depressed, the opening degree of the accelerator pedal, whether the brake pedal is depressed, the opening degree of the brake pedal, or the like, and the application is not limited thereto.
It will be appreciated that the determined first target gear may be different when the driver shift operation information is different and the vehicle state information is different.
For example, the determined first target gear may have various situations, for example, it may be a parking gear (P gear), a forward gear (D gear), a reverse gear (R gear), or a neutral gear (N gear), which is not limited in the present application.
For example, in the case where the current gear of the vehicle is the parking gear and the driver depresses the brake pedal to switch the forward gear, then the first target gear may be determined to be the forward gear. Alternatively, in the case where the vehicle front range is the low forward range and the driver shifts to the park range, the first target range may be determined to be the park range. Alternatively, in the case where the current gear of the vehicle is the forward gear at low speed and the driver shifts to the reverse gear, then the first target gear may be determined to be the reverse gear, or the like, to which the present application is not limited.
Optionally, the vehicle controller VCU may include a plurality of controllers, control software or processors, and in order to ensure reliability of data acquisition and transmission, a plurality of different processors may be provided to determine the target gear based on the detected driver shift operation information and the detected vehicle state information, respectively, and the application is not limited thereto.
Step 102, determining a target gear based on the first target gear and the received second target gear.
The second target gear information may be other controllers, or a processor, or a first processor in a whole vehicle controller, application layer software L1, or the like, and corresponds to the determined gear information based on the determined driver shift operation information and vehicle state information.
For example, the safety function software L2 in the current vehicle controller may determine the first target gear based on the determined driver shift operation information and the vehicle state information, the application layer software L1 in the vehicle controller may determine the second target gear based on the determined driver shift operation information and the vehicle state information, and the like, which is not limited in this application.
It will be appreciated that, generally, when a shift of a vehicle is required, the L1 in the overall vehicle controller may directly shift the shift of the vehicle after receiving the driver shift operation information. If the L1 is abnormal, for example, the gear operation information is determined to be wrong, the data transmission is abnormal, etc., the gear switching of the vehicle may be problematic, and the safety of the vehicle may be affected. Therefore, in the embodiment of the application, in order to ensure the safety of the vehicle, after determining the second target gear based on the driver gear shifting operation information and the vehicle state information, the second target gear may be sent to L2, then the L2 may determine the first target gear based on the driver gear shifting operation information and the vehicle state information acquired by itself, determine the target gear based on the first target gear and the received second target gear, and then perform subsequent processing based on the target gear.
Optionally, after receiving the second target gear, it may be determined whether the first target gear is consistent with the received second target gear, where the first target gear and the second target gear are arbitrated to determine the target gear if the first target gear is inconsistent with the second target gear, and where the second target gear is determined to be the target gear if the first target gear is consistent with the second target gear.
It will be appreciated that if the second target gear is consistent with the first target gear, the second target gear may be deemed to be judged as correct, and then the second target gear may be determined to be the target gear. If the second target gear is inconsistent with the first target gear, it can be determined that the second target gear may be abnormal in the determining process, and in this case, in order to ensure the safety of the vehicle, the second target gear and the first target gear may be arbitrated to determine the target gear.
When the first target gear is inconsistent with the second target gear, the different first target gear and the different second target gear may also have different corresponding arbitration results, so that the determined target gear may also be different, for example, a parking gear, or a non-parking gear such as a neutral gear (N gear), or other gears may also be possible, and the application is not limited to this.
Therefore, in the embodiment of the application, in order to avoid the error of the second target gear caused by the abnormality of the L1, the first target gear can be used for verifying the second target gear, when the second target gear is consistent with the first target gear, the second target gear can be determined as the target gear, and when the second target gear is inconsistent with the first target gear, the arbitration can be performed, so that the safety of the vehicle is not influenced when the vehicle performs subsequent processing based on the arbitrated target gear, and the safety of the vehicle is ensured.
Step 103, controlling a motor parking lock of the vehicle based on the target gear.
It will be appreciated that to further ensure the safety of the vehicle, the control of the motor park lock of the vehicle may also be different for different target gear positions.
Alternatively, the locking instruction may be sent to the motor parking lock when the target gear is the parking gear, and the unlocking instruction may be sent to the motor parking lock when the target gear is the non-parking gear.
The non-parking gear may be R gear, N gear, D gear, etc., which is not limited in the present application.
It will be appreciated that during parking of the vehicle, the motor of the vehicle no longer outputs torque in order to allow the vehicle to come to rest at a reduced speed. Therefore, in the embodiment of the application, if the target gear is the parking gear, a locking instruction can be sent to the motor parking lock, so that the motor parking lock can be locked based on the locking instruction.
Or, in a process that the vehicle needs to travel, in order to enable the vehicle to perform corresponding acceleration traveling or the like, the motor of the vehicle needs to output corresponding torque. Therefore, in the embodiment of the application, if the target gear is a non-parking gear, in order to ensure that the motor can normally output torque, an unlocking instruction can be sent to the motor parking lock, so that the motor parking lock can be in an unlocking state based on the unlocking instruction, and the torque output is ensured.
The non-parking gear may be R gear, N gear, D gear, etc., which is not limited in the present application. Therefore, in the embodiment of the application, in order to improve the accuracy of vehicle control, a corresponding control instruction can be sent to the motor parking lock of the vehicle based on the non-parking gear, so that the accuracy of vehicle control can be improved as much as possible, and conditions are provided for guaranteeing the safety of the vehicle.
Step 104, determining a first actual gear based on the target gear and the current state of the motor parking lock of the vehicle.
After the motor parking lock of the vehicle is controlled based on the target gear, the current state of the motor parking lock can be detected again to determine whether the current state of the motor parking lock is matched with the target state, and further, based on the matched state, the corresponding first actual state is determined.
Step 105, determining the current actual gear based on the first actual gear and the received second actual gear.
It will be appreciated that after receiving the second actual gear, the second actual gear may be matched with the determined first actual gear, and then the current actual gear is determined according to a result of matching between the first actual gear and the received second actual gear. For example, when the first actual gear is consistent with the second actual gear, any one of the first actual gear and the second actual gear can be determined to be the current actual gear, and when the first actual gear and the second actual gear are inconsistent, the current actual state can be further determined based on the first actual gear and the second actual gear in order to ensure the safety of the vehicle.
And 106, controlling the vehicle based on the current actual gear.
It will be appreciated that in order to improve the safety of the vehicle, the first actual gear may be matched with the second actual gear, and when the two gears are identical, the current first actual gear and the second actual gear may be considered as reliable gears, the second actual gear may be determined as the current actual gear, and the first actual gear may be determined as the current actual gear. When the two gears are inconsistent, the vehicle can arbitrate again, so that the vehicle is controlled based on the current actual gear obtained after arbitration, the safety of the vehicle is not influenced, and the safety of the vehicle is ensured.
For example, when the current actual state is a parking gear, it may be determined that the current output torque of the vehicle motor may be zero, or the like, which is not limited by the present application.
According to the embodiment of the application, the first target gear can be determined according to the gear shifting operation information of the driver and the vehicle state information, then the target gear can be determined based on the first target gear and the received second target gear, the motor parking lock of the vehicle is controlled based on the target gear, then the first actual gear can be determined based on the target gear and the current state of the motor parking lock of the vehicle, and the current actual gear is determined based on the first actual gear and the received second actual gear, and then the vehicle is controlled based on the current actual gear. Therefore, in the process of switching the gear of the vehicle, the received second target gear can be verified based on the determined first target gear to determine the target gear, then the current actual gear is determined based on the determined first actual gear and the received second actual gear, and then the vehicle is controlled, so that the gear control of the vehicle is more reliable, and the safety and reliability of the running of the vehicle are improved.
As shown in fig. 2, the gear control method of the vehicle may include the steps of:
step 201, determining a first target gear according to driver shift operation information and vehicle state information.
Step 202, determining a target gear based on the first target gear and the received second target gear.
It will be appreciated that it may be determined whether the first target gear is consistent with the received second target gear, and if the first target gear is inconsistent with the second target gear, the first target gear and the second target gear may be arbitrated to determine the target gear, and if the first target gear is consistent with the second target gear, the second target gear may be determined to be the target gear.
Optionally, when the first target gear is inconsistent with the second target gear, if the first target gear is a parking gear or the second target gear is a parking gear, the target gear may be determined to be the parking gear, and if the first target gear and the second target gear are both non-parking gears, the target gear may be determined to be the non-parking gear.
For example, if the first target gear is a parking gear and the second target gear is a non-parking gear such as a forward gear, the first target gear and the second target gear are inconsistent, so as to ensure safety of the vehicle, the target gear may be determined to be the parking gear; if the first target gear is a non-parking gear, such as a climbing gear, and the second target gear is a parking gear, the first target gear is inconsistent with the second target gear, so that the target gear can be determined to be the parking gear in order to ensure the safety of the vehicle, and the like, which is not limited in the application.
Step 203, controlling a motor parking lock of the vehicle based on the target gear.
It can be appreciated that, when the target gear is the parking gear, a locking instruction may be sent to the motor parking lock, so that the motor parking lock is locked based on the locking instruction; or, if the target gear is a non-parking gear, an unlocking instruction may be sent to the motor parking lock, so that the motor parking lock is in an unlocking state based on the unlocking instruction, which is not limited in the present application.
Step 204, determining that the first actual gear is the parking gear when the target gear is the parking gear and the current state of the motor parking lock is the locking state.
In step 205, when the target gear is the parking gear and the current state of the motor parking lock is the unlocked state, the first actual gear is determined to be the neutral gear.
It will be appreciated that when the target gear is in park, the vehicle may be considered to be currently parked, and in so doing, in order to allow the vehicle to come to rest at a reduced speed, the motor of the vehicle should not be subject to torque output, and the motor parking lock should be in a locked state. Therefore, in the embodiment of the application, the current state of the motor parking lock of the vehicle can be detected to determine whether the motor parking lock is matched with the target state.
When the target gear is the parking gear, if the motor parking lock is in the locking state currently, the target gear can be determined to be matched with the current motor parking lock state, and at the moment, the first actual gear can be determined to be the parking gear. When the target gear is the parking gear, if the motor parking lock is in the unlocking state currently, the target gear and the current motor parking lock state can be determined to be not matched, and at the moment, in order to ensure the safety of the vehicle, the first actual gear can be determined to be the neutral gear.
In step 206, in the case that the target gear is the non-parking gear, the first actual gear is determined to be the non-parking gear.
The non-parking gear can be a neutral gear or other gears, if the target gear is a non-parking gear, the non-parking gear can be determined to be a first actual gear in order to ensure the safety of the vehicle, so that accidents caused by gear switching of the vehicle are avoided.
Step 207, determining whether the first actual gear is consistent with the received second actual gear.
The second actual gear may be understood as an actual gear of the vehicle determined by L1 based on the current target gear and the current state of the motor parking lock of the vehicle, and may be transmitted to L2, or the like, which is not limited in the present application.
In step 208, in case the first actual gear is consistent with the second actual gear, the first actual gear is determined as the current actual gear.
If the first actual gear is consistent with the second actual gear, the determination of the current actual gear may be considered to be correct, at this time, the first actual gear may be determined as the current actual gear, or the second actual gear may be determined as the current actual gear, or the like, and then the vehicle may be controlled based on the determined current actual gear, so that the safety of the vehicle may be improved as much as possible.
For example, if the first actual gear and the second actual gear are both parking gears, and the first actual gear and the second actual gear are the same, then the current actual gear may be determined to be the parking gear; alternatively, if the first actual gear and the second actual gear are both neutral, and both are consistent, then the current actual gear may be determined to be neutral, and the application is not limited thereto.
Step 209, arbitrating the first actual gear and the second actual gear to determine the current actual gear in case the first actual gear is inconsistent with the second actual gear.
If the first actual gear is inconsistent with the second actual gear, the accuracy of the judgment of the current actual gear may not be considered to be high enough, and at this time, in order to ensure the safety of the vehicle, the first actual gear and the second actual gear may be arbitrated to determine the current actual gear.
Alternatively, in case the first actual gear does not coincide with the second actual gear, the neutral gear may be determined as the current actual gear.
For example, if the first actual gear is a parking gear and the second actual gear is a neutral gear, the neutral gear may be determined to be the current actual gear, and the like, which is not limited in the present application.
Step 210, controlling the vehicle based on the current actual gear.
Optionally, after determining the current actual gear, the corresponding output torque may be determined based on the current actual gear, and then the vehicle may be controlled according to the determined output torque.
