[0025] Embodiment 1

[0026] According to an embodiment of the present application, an embodiment of a vehicle control method is provided. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that herein.

[0027] Figure 1 is a schematic diagram of an optional vehicle control method according to an embodiment of the present application, as Figure 1 shown, the method comprises the following steps:

[0028] Step S102, detecting the vehicle state of the target vehicle.

[0029] In step S102, the vehicle state of the target vehicle can be detected by an electronic device, a processor, an application system, etc. In this embodiment, the state of the target vehicle can be detected by a target controller on the target vehicle, wherein the target controller can be a vehicle control unit (VCU), or other controller with certain computing power and capable of analyzing signals and determining and processing faults, and can also be a domain controller. The target vehicle can be a pure electric vehicle loaded with an electronic gear shifter EGSM or a hybrid vehicle loaded with an electronic gear shifter, which can be a car or other types of vehicles such as an electric tricycle, etc. The electronic gear shifter is used to monitor the operation stroke and position signal of the driver dialing the gear handle and send the related signals to the target controller or other actuators to realize electronic gear shifting, wherein the actuator can be at least one of a motor, an engine, a transmission, a P-gear controller, and a brake caliper. The vehicle state can represent the in-vehicle environment of the target vehicle, whether it is charged or not, etc.

[0030] Optionally, the target controller can detect the vehicle state of the target vehicle through at least one sensor preset on the target vehicle, or can collect the surrounding environment and in-vehicle environment of the target vehicle through an image acquisition device.

[0031] In step S104, when the target vehicle is detected to be in the target vehicle state, the communication state between the target controller of the target vehicle and the gear shifter controller of the target vehicle is detected, wherein the target vehicle state is one of the following: wired charging state, wireless charging state, and driver leaving vehicle state.

[0032] In step S104, as shown in Figure 2 When the target controller detects that the target vehicle is in at least one of the wired charging state, the wireless charging state, and the driver leaving vehicle state, i.e., in the target vehicle state, the target controller can detect the communication state between the target controller and the gear shifter controller of the target vehicle. The gear shifter controller can be a P-gear controller or an electronic parking brake (EPB). The P-gear controller locks the gear of the transmission of the target vehicle and prohibits the rotation of the gear to engage the parking gear to achieve parking. The electronic parking brake increases the friction between the brake caliper and the brake disc by clamping the brake caliper of the target vehicle to prevent the tire from rotating to achieve parking.

[0033] Optionally, the target controller preferentially detects the communication state with the P-gear controller. For vehicles without a P-gear controller, the target controller can detect the communication state with the electronic parking brake. In addition, the target controller can also detect the communication state with the aforementioned electronic gear shifter.

[0034] It should be noted that by determining whether to adjust the gear of the target vehicle to the parking gear when the target vehicle is in at least one of the wired charging state, the wireless charging state, and the driver away-from-vehicle state, the judgment accuracy is improved by avoiding the misjudgment of whether to switch the parking gear caused by the lack of recognition of the working condition of the vehicle in the prior art. In addition, by prioritizing the judgment of the vehicle state of the target vehicle, and not performing subsequent judgments when the target vehicle is not in the target vehicle state, invalid judgment work is avoided, thereby improving the work efficiency of the present application.

[0035] In step S106, when it is detected that the target controller and the gear shift controller are in normal communication, the gear type of the current gear of the target vehicle is determined.

[0036] In this case, when the communication between the target controller and the P-gear controller or the electronic parking system is abnormal, the P-gear controller or the electronic parking system will not be able to accurately execute the control instructions of the target controller, and the target controller will not be able to accurately receive the feedback of the state of the P-gear controller or the electronic parking system. Therefore, at this time, it is not necessary to further determine whether to automatically switch the gear of the target vehicle to the parking gear. It should be noted that, as shown in Figure 2 When the communication between the target controller and the P-gear controller or the electronic parking system is abnormal, the target controller can acquire and store relevant communication fault information, and give an alarm prompt for later troubleshooting by maintenance personnel.

[0037] Optionally, when the target controller determines that it is in normal communication with the P-gear controller or the electronic parking system, the target controller can determine the gear type of the current gear of the target vehicle. In addition, the target controller can also determine the gear type of the current gear of the target vehicle when it is determined that it is in normal communication with the P-gear controller or the electronic parking system, and it is determined that it is in normal communication with the electronic gear shifter.

[0038] Optionally, the target controller can determine the gear type of the current gear of the target vehicle through the electronic gear shifter, or the P-gear controller, or the electronic parking system. The target controller can also identify the working state of the relevant devices in the target vehicle through various sensors, and determine the gear type of the current gear of the target vehicle according to the working state of the relevant devices.

[0039] It should be noted that by determining the gear type of the current gear of the target vehicle when the normal communication between the target controller and the gear controller is determined, the error gear information obtained by the target controller when the abnormal communication between the target controller and the gear controller is avoided, thereby causing the misjudgment of whether to switch the parking gear, thereby improving the judgment accuracy. In addition, since the effective adjustment of the gear cannot be realized when the abnormal communication between the target controller and the gear controller is realized, the subsequent judgment is no longer performed under the condition of abnormal communication, and the invalid judgment work is also avoided, thereby improving the work efficiency of the present application.

[0040] Step S108, when it is determined that the current gear is a non-parking gear, the gear controller is controlled to adjust the current gear to the parking gear.

[0041] In step S108, as shown in Figure 2 When the target controller determines that the current gear is a non-parking gear, the target controller can send a control instruction to the gear controller to adjust the current gear to the parking gear. Thus, the effect of automatic parking is realized.

[0042] Based on the scheme defined in steps S102 to S108, it can be known that in the embodiment of the present application, the way of sequentially detecting the vehicle state, the communication state and the gear type of the target vehicle to determine whether to switch the current gear to the parking gear is adopted. By detecting the vehicle state of the target vehicle, and detecting the communication state between the target controller and the gear controller of the target vehicle when the target vehicle is in the target vehicle state, and then determining the gear type of the current gear of the target vehicle when the normal communication between the target controller and the gear controller is detected, the current gear is adjusted to the parking gear by the gear controller when it is determined that the current gear is a non-parking gear. The target vehicle state is one of the following: wired charging state, wireless charging state, and driver leaving vehicle state.

[0043] It is easy to note that in the above process, by judging the communication state of the target vehicle again when the target vehicle is in at least one of the wired charging state, the wireless charging state, and the driver leaving the vehicle state, the misjudgment of whether to switch the parking gear caused by the lack of identification of the working condition of the vehicle in the prior art is avoided. Further, by determining the gear type of the current gear of the target vehicle again when the normal communication between the target controller and the gear controller is determined, the misjudgment of whether to switch the parking gear caused by the target controller obtaining incorrect gear information when the communication between the target controller and the gear controller is not normal is avoided, thereby improving the accuracy of the judgment of whether to switch to the parking gear. In addition, by performing subsequent judgment again when the target vehicle is in the target vehicle state and the communication is normal, or performing gear switching again when it is determined that the current gear is not the parking gear, invalid judgment work or gear switching work is avoided, thereby improving the work efficiency of the present application.

[0044] Therefore, the scheme provided by the present application achieves the purpose of determining whether to switch the current gear to the parking gear by sequentially detecting the vehicle state, the communication state, and the gear type of the target vehicle, thereby achieving the technical effect of improving the accuracy of the judgment of whether to switch to the parking gear, and further solving the technical problem of low accuracy of the related method in the prior art for judging whether to switch the gear of the vehicle to the parking gear.

[0045] In an optional embodiment, in the process of detecting the vehicle state of the target vehicle, the target controller can detect the current authority of the target controller.

[0046] Among them, the target vehicle is provided with an entertainment host controller (IVI, in-Vehicle Infotainment), and the entertainment host controller can receive an authority adjustment instruction and adjust the current authority of the target controller to allow the target controller to control the parking gear or adjust the current authority to prohibit the target controller from controlling the parking gear in response to the authority adjustment instruction.

[0047] Specifically, the entertainment host controller can receive a permission adjustment instruction input by an occupant in the vehicle or a permission adjustment instruction sent by the vehicle owner through a mobile terminal, and adjust the current permission of the target controller based on the permission adjustment instruction, wherein the current permission is used to represent whether the target vehicle has enabled the function of automatically switching to the parking gear, and when the current permission is to prohibit the target controller from controlling the parking gear, even if the target controller sends a control instruction, the gear controller cannot switch the current gear to the parking gear. And after the function of automatically switching to the parking gear is turned off, the driver can manually switch to N gear. Thus, when the premise condition is met, the phenomenon that the parking gear hinders the towing repair or even damages the vehicle parts when the target controller is always allowed to control the parking gear if the vehicle is stranded and needs to be towed is avoided, so that the application is more in line with the actual demand and the applicability of the application is improved.

[0048] Further, as shown in Figure 2 The target controller can send a permission reading instruction to the entertainment host controller to determine the current permission of the target controller, and the target controller can also receive the permission information sent by the entertainment host controller in real time to determine the current permission, that is, to determine whether the target vehicle has enabled the function of automatically switching to the parking gear.

[0049] Further, when it is detected that the current permission represents that the target controller is allowed to control the parking gear, the target controller can detect the working state of the target controller, and when it is detected that the target controller is in a normal working state, the vehicle state of the target vehicle is detected.

[0050] Optionally, in this embodiment, the normal working state at least includes the case that the target controller is in an IgON state or a READY state, wherein the IgON state at least represents that the target controller can control the electrical equipment in the target vehicle to work normally at this time, and the READY state represents that the target controller can control the target vehicle to start normally. When the target controller determines that it is in a normal working state, the vehicle state of the target vehicle is detected.

[0051] It should be noted that by sequentially detecting the current permission and the working state of the target controller, the judgment condition for judging whether to adjust the current gear to the parking gear is enriched, so that the judgment accuracy can be further improved.

[0052] In an optional embodiment, in the process of detecting the vehicle state of the target vehicle, the target controller determines that the target vehicle is in a wired charging state if it detects that the charging port of the target vehicle is connected with the charging device; determines that the target vehicle is in a wireless charging state if it detects a wireless charging signal; and determines that the target vehicle is in a driver leaving state if it detects that the strokes of the brake pedal and the accelerator pedal of the target vehicle are preset values and detects that the seat state of the driver seat switches from a person state to an empty state.

[0053] Optionally, the target controller can detect whether the charging port of the target vehicle is connected with the charging device through a charging gun type identification sensor on the target vehicle, so as to determine whether the target vehicle is in a wired charging state, wherein the charging gun type identification sensor is used to monitor and report the resistance value of the inserted charging and discharging gun to the target controller. The target controller can detect a wireless charging signal through a wireless on-board charger (WOBC) to determine whether the target vehicle is in a wireless charging state, wherein the wireless on-board charger is used to monitor and report the alignment state of the target vehicle and the charging base to the target controller, and the wireless charging signal is used to represent that the alignment state of the target vehicle and the charging base is a successful alignment state.

[0054] Optionally, the target controller can at least determine whether the target vehicle is in a driver leaving state through a brake pedal position sensor, a throttle pedal position sensor and a body control module (BCM). Specifically, the brake pedal position sensor is used to monitor and report the position signal of the current brake pedal, and the throttle pedal position sensor is used to monitor and report the position signal of the current throttle pedal, so that the target controller can determine the strokes of the brake pedal and the accelerator pedal of the target vehicle; and the body control module is at least used to realize driver seat pressure sensing, and can also be used to identify and report the key door position action state, the vehicle door opening and closing action state and the driver seat belt insertion and extraction action state to the target controller.

[0055] Further, when the target controller determines that the strokes of the brake pedal and the accelerator pedal of the target vehicle are preset values, and the seat state of the driver seat switches from a person state to an empty state, it can be determined that the target vehicle is in a driver leaving state. In this embodiment, the preset value is preferably 0.

[0056] Further, the target controller can further determine that the target vehicle is in a driver leaving state when it determines that the strokes of the brake pedal and the accelerator pedal of the target vehicle are preset values, the seat state of the driver seat switches from a person state to an empty state, and it identifies that the seat belt switches from insertion to extraction and the vehicle door switches from closing to opening.

[0057] Optionally, in another embodiment of the present application, the target controller can also achieve the detection of the vehicle state of the target vehicle by setting image acquisition devices near the charging port, near the brake pedal and the accelerator pedal, and near the driver's seat of the vehicle, and controlling the image acquisition devices to acquire the surrounding pictures in real time.

[0058] It should be noted that by detecting the charging port of the target vehicle, the wireless charging signal, and the brake pedal, the accelerator pedal, and the seat state of the target vehicle, the effective detection of the vehicle state of the target vehicle can be achieved.

[0059] In an optional embodiment, in the process of determining the gear type of the current gear of the target vehicle, the target controller can obtain the current speed of the target vehicle, so as to determine the gear type when the current speed is less than a preset speed.

[0060] Optionally, as shown in Figure 2 After determining that the target controller and the gear shift controller are in normal communication, the target controller can obtain the current speed through the electronic stability program (ESP) and determine the gear type when the current speed is less than a preset speed. Preferably, the preset speed is 2 km / h, and optionally, the preset speed can also be set to different values according to different use scenarios or vehicles. Conversely, if the current speed is greater than or equal to the preset speed, the speed is reduced to meet the condition.

[0061] In the comparison between the current speed and the preset speed, the absolute value of the current speed can be compared with the preset speed. Since the forced engagement of the parking gear at a high speed can damage the vehicle parts, and the negative acceleration suddenly added to the vehicle body at this time can also greatly reduce the driving experience, by first determining whether the speed meets the condition and then determining whether to switch the current gear to the parking gear, the driving safety is improved.

[0062] In an optional embodiment, after controlling the gear shift controller to adjust the current gear to the parking gear, the target controller can detect the gear shift state of the gear shift controller, and in the case that the gear shift state represents a gear shift failure, obtain gear shift failure information, then store the gear shift failure information, and generate prompt information for prompting the gear shift failure.

[0063] Optionally, as shown in Figure 2 When the gear shift controller receives the control instruction sent by the target controller to adjust the current gear to the parking gear, the gear shift controller performs the work of adjusting the gear, and sends information representing the successful gear shift to the target controller after the adjustment is successful. If the target controller does not receive the information representing the successful gear shift within a preset feedback time (i.e. Figure 2If the target controller does not receive the information indicating the shift success within the preset feedback time, the shift state of the shift controller is determined as a shift failure state, otherwise, if the target controller receives the information indicating the shift success within the preset feedback time, the shift state of the shift controller is determined as a shift success state. In the embodiment, the preset feedback time is preferably 1 s, and the preset feedback time can also be different according to different application scenarios or vehicles.

[0064] The target vehicle is further provided with an instrument controller and an instrument display IC. When the target controller is waiting for the shift controller to adjust the gear, the target controller can control the instrument display to display relevant information through the instrument controller. For example, the instrument display mode of the current gear is changed to: current gear "(N / D / R)→P", and the whole is flickered with a frequency of 3 Hz. After the gear adjustment is successful, the current gear is displayed as the parking gear and is always on, so as to realize rich prompt information.

[0065] Further, if the shift state of the shift controller is determined as the shift failure state, the target controller can obtain the shift failure information sent by the shift controller, such as the fault code generated by the shift controller during the shift process, and store the fault code in a storage area such as a database, a memory, a cloud server, etc. At the same time, the target controller can also control the instrument display to display relevant information through the instrument controller. For example, the instrument displays the prompt text "Gear automatic return P fails, please repair", the text is displayed for 5 seconds, accompanied by an alarm prompt sound, and the current gear is still displayed as the gear before returning P, so as to realize rich prompt information.

[0066] It should be noted that the shift state of the shift controller is detected to ensure the authenticity of the determined gear of the target vehicle at all times. In addition, the fault code generated during the automatic switching of the parking gear is stored, which is convenient for fault analysis by the operator.

[0067] Therefore, the scheme provided in the present application achieves the purpose of sequentially detecting the vehicle state, the communication state and the gear type of the target vehicle to determine whether to switch the current gear to the parking gear, thereby achieving the technical effect of improving the judgment accuracy of whether to switch to the parking gear, and further solving the technical problem of low judgment accuracy of whether to switch the vehicle gear to the parking gear in the prior art.

[0069] According to the embodiments of the present application, a vehicle is provided, in which the vehicle control method described above is applied.

[0070] Optionally, the foregoing vehicle can comprise a target controller, an electronic gear shifter, a P-gear controller, an electronic parking system, a vehicle body stability system, a vehicle body controller, a wireless charging machine, a charging gun type identification sensor, a brake pedal position sensor, a throttle pedal position sensor, an entertainment host controller, an instrument controller and an instrument display, and a storage unit.

[0071] The target controller is configured to receive, identify and analyze signals from various controllers and sensors, such as identifying whether a charging and discharging gun is inserted and its type, analyzing the opening degree of the accelerator pedal and the brake pedal, and analyzing the target gear of the driver.

The storage unit is also configured to store the setting state of the automatic return to parking gear function, which at least includes the current permission, to ensure that the driver can maintain the final setting state of the last driving cycle when the next power is turned on.

[0077] It is easy to note that the vehicle provided in the present application avoids the misjudgment of whether to switch the parking gear caused by the lack of recognition of the working condition of the vehicle by judging the communication state of the target vehicle when the target vehicle is in at least one of the wired charging state, the wireless charging state, and the driver leaving the vehicle state. Further, by determining the gear type of the current gear of the target vehicle when normal communication is determined between the target controller and the gear shift controller, the misjudgment of whether to switch the parking gear caused by the target controller obtaining incorrect gear information when abnormal communication occurs between the target controller and the gear shift controller is avoided, thereby improving the accuracy of the judgment of whether to switch to the parking gear. In addition, by performing subsequent judgment when the target vehicle is in the target vehicle state and the communication is normal, or performing gear switching when it is determined that the current gear is not the parking gear, invalid judgment work or gear switching work is avoided, thereby improving the work efficiency of the present application.

[0078] Therefore, the scheme provided in the present application achieves the purpose of determining whether to switch the current gear to the parking gear by sequentially detecting the vehicle state, the communication state, and the gear type of the target vehicle, thereby achieving the technical effect of improving the accuracy of the judgment of whether to switch to the parking gear, and further solving the technical problem of low accuracy of the related method in the prior art for judging whether to switch the gear of the vehicle to the parking gear.
