[0027] Additional aspects and advantages of the present invention will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present invention. Description of the Drawings

[0028] The above and / or additional aspects and advantages of the present invention will become apparent and be readily understood from the description of the embodiments in conjunction with the following drawings, in which:

[0029] Figure 1 is a flowchart of a control method for vehicle catapult start according to an embodiment of the present invention;

[0030] Figure 2 is a working schematic diagram of a torque oscillation random generator according to an embodiment of the present invention;

[0031] Figure 3 is a block diagram of a control device for vehicle catapult start according to an embodiment of the present invention. Detailed Embodiments

[0032] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0033] The control method for vehicle catapult start according to the embodiments of the present invention will be described below.

[0034] Reference will be made below to Figure 1 and Figure 2 to describe the control method for vehicle catapult start according to the embodiments of the present invention. As Figure 1 shown, the control method for vehicle catapult start according to the embodiments of the present invention includes at least step S1-step S4.

[0035] Step S1, upon receiving a catapult start instruction, determine whether the vehicle meets the conditions for entering the catapult start preparation mode.

[0036] In the embodiment, when the user has a catapult start requirement, a catapult start command is issued. After the vehicle receives the catapult start instruction, the current state of the vehicle is judged. Specifically, the user can issue a catapult start instruction by triggering a dedicated button or switch provided in the vehicle. Alternatively, a catapult start instruction can be issued by inputting specific voice information.

[0037] Specifically, after receiving the launch control instruction, in response to the launch control instruction, it is determined whether the vehicle meets the conditions for entering the launch control preparation mode. For example, it is determined the current driving state of the vehicle, the time since the vehicle last exited the launch control preparation mode, the time since the vehicle last exited the launch control mode, the maximum available torque of the vehicle's powertrain, the maximum available power of the powertrain, the absence of preset types of faults in the powertrain, the vehicle speed, the state of the vehicle's brake pedal, the gear position of the vehicle, the depth of the vehicle's accelerator pedal, the driving mode of the vehicle, and the steering angle of the vehicle's steering wheel. By judging the above conditions, it is determined whether the vehicle meets the conditions for entering the launch control preparation mode.

[0038] Step S2, if so, control the vehicle to enter the launch control preparation mode to activate the vehicle's torque oscillation random generator, and the torque oscillation random generator randomly outputs multiple oscillation torques with random durations within a preset torque range.

[0039] In an embodiment, the torque oscillation random generator can be integrally arranged in the VCU (Vehicle Controller Unit). If the vehicle meets the conditions for entering the launch control preparation mode, it is considered that the launch control preparation mode of the vehicle is activated. At this time, control the vehicle to enter the launch control preparation mode and activate the vehicle's torque oscillation random generator to randomly generate oscillation torques, giving the vehicle a strong personality, so that the vehicle has richer performance in the launch control preparation stage, enhancing the communication between the driver and the vehicle, improving the driving pleasure while enhancing the user experience.

[0040] For example, as Figure 2 shown, it is a working schematic diagram of the torque oscillation random generator according to an embodiment of the present invention. After activating the vehicle's torque oscillation random generator, control the output torque of the torque oscillation random generator to randomly output multiple oscillation torques with random durations within a preset torque range. For example, control the torque oscillation random generator to randomly output multiple oscillation torques with random durations within the torque range between the maximum torque value and the minimum torque value. Thus, a strong personality can be given to the vehicle, enhancing the communication between the user and the vehicle, and further improving the driving pleasure. As Figure 2 known, the maximum torque value is denoted as Tq_Max, and the minimum torque value is denoted as Tq_Min. Control the torque oscillation random generator to randomly output multiple oscillation torques with random durations within a preset range, that is, control the torque oscillation random generator to randomly output multiple oscillation torques with random durations within the torque range of Tq_Max and Tq_Min. It can be understood that the maximum torque value Tq_Max and the minimum torque value Tq_Min of the torque oscillation random generator can be calibrated according to specific torque requirements.

[0041] Step S3: Determine whether the vehicle meets the conditions for entering the launch control mode.

[0042] In the embodiment, after determining that the vehicle enters the launch control preparation mode, the state and braking force of the vehicle's brake pedal are judged, and the launch state of the vehicle is judged according to the state and braking force of the brake pedal, so as to facilitate determining whether the vehicle meets the conditions for entering the launch control mode.

[0043] Step S4: If the vehicle meets the conditions for entering the launch control mode, control the vehicle to enter the launch control mode to control the vehicle's power system to operate at the current maximum output torque.

[0044] In the embodiment, controlling the vehicle's power system to operate at the current maximum output torque means controlling the vehicle's power system to operate at the maximum output torque at the moment when the vehicle starts to run, so as to achieve the acceleration of the vehicle. It can be understood that when the vehicle is a pure electric vehicle, the power system is a motor, that is, controlling the motor to operate at the maximum output torque. When the vehicle is a fuel-powered vehicle, the power system is an engine, that is, controlling the engine to operate at the maximum output torque. When the vehicle is a hybrid vehicle, the power system is an engine and a motor, that is, controlling the engine and the motor to cooperate with each other to operate at the maximum output torque.

[0045] Specifically, after determining that the vehicle meets the conditions for entering the launch control mode, control the vehicle to enter the launch control mode to control the vehicle's power system to operate at the current maximum output torque, so as to achieve the launch control of the vehicle.

[0046] According to the vehicle launch control method of the embodiment of the present invention, when receiving a launch command, it is judged whether the vehicle meets the conditions for entering the launch control preparation mode. When it is determined that the vehicle meets the conditions for entering the launch control preparation mode, control the vehicle to enter the launch control preparation mode and activate the vehicle's torque oscillation random generator to randomly generate oscillation torque, giving the vehicle a strong personality, so that the vehicle has richer performance during the launch control preparation stage, enhancing the communication between the driver and the vehicle, improving the driving pleasure and at the same time improving the user experience.

[0047] In some embodiments, the torque oscillation random generator randomly outputs multiple oscillation torques with random durations within a preset torque range, including: obtaining the remaining power of the vehicle battery system, and controlling the torque oscillation random generator to randomly output multiple oscillation torques with random durations within the torque range of the maximum oscillation torque and the minimum oscillation torque, wherein when the remaining power is less than the preset power, the maximum oscillation torque and the minimum oscillation torque are respectively less than the preset maximum oscillation torque and the preset minimum oscillation torque corresponding to the preset power. Specifically, when the torque oscillation random generator outputs multiple oscillation torques with random durations, it is necessary to obtain the remaining power of the vehicle battery system. When the remaining power of the vehicle battery system is lower than the preset power, it is considered that the battery power of the vehicle battery system is low. At this time, the torque oscillation random generator is controlled to randomly output multiple oscillation torques with random durations within the torque range of the maximum oscillation torque and the minimum oscillation torque, so as to remind the driver of the low battery power of the vehicle battery system through the sense of vibration.

[0048] In some embodiments, the launch control preparation mode is divided into at least one time stage, and the oscillation frequencies are different in different time stages. It can be understood that the launch control preparation mode can be divided into at least one time stage, such as two or three time stages, and in different time stages, the oscillation frequencies of the oscillation torques output by the torque oscillation random generator are different.

[0049] In some embodiments, the launch control preparation mode is divided into at least one time stage, and the maximum oscillation torque and the minimum oscillation torque are different in different time stages. Specifically, the launch control preparation mode can be divided into at least one time stage. In different time stages, the maximum oscillation torque and the minimum oscillation torque output by the torque oscillation random generator are different. Figure 2 As can be seen, in different time stages, for example, when just entering the launch control preparation mode, the corresponding maximum oscillation torque is torque value 1, and the corresponding minimum oscillation torque is torque value 2; after entering the launch control preparation mode for a period of time, the corresponding maximum oscillation torque is torque value 2, and the corresponding minimum oscillation torque is torque value 3. Thus, it can be seen that in different time stages, the maximum torque of the oscillation torque and the torque of the oscillation torque are significantly different.

[0050] In some embodiments, after the torque oscillation random generator randomly outputs multiple oscillation torques with random durations within the preset torque range, it further includes: after a first preset time, controlling the torque oscillation random generator to continuously output a target oscillation torque, and the target oscillation torque is the average value of the multiple oscillation torques.

[0051] For example, Figure 2It can be known that after the torque oscillation random generator outputs the oscillation torque for the first preset time, for example, after 4S, the torque oscillation random generator is controlled to continuously output the target oscillation torque and keep the target oscillation torque unchanged, so as to facilitate the vehicle to smoothly enter the catapult start stage. Among them, the target oscillation torque is denoted as Tq_Ave for example.

[0052] In some embodiments, the conditions for entering the catapult start preparation mode include: the vehicle is in a state of waiting to drive; and, the time since the vehicle last exited the catapult start preparation mode is greater than or equal to the second preset time; and, the time since the vehicle last exited the catapult start mode is greater than or equal to the third preset time; and, the maximum available torque of the vehicle's power system is greater than the preset torque threshold, and the maximum available power of the power system is greater than the preset power threshold; and, there is no fault of the preset type in the power system; and, the vehicle speed is less than the preset speed threshold; and, the vehicle's brake pedal is depressed and the braking force is greater than the preset braking force threshold; and, the vehicle is in the preset gear; and, the depth of the vehicle's accelerator pedal is greater than the preset depth threshold; and, the vehicle's driving mode is in the set driving mode; and, the steering angle of the vehicle's steering wheel is less than the preset angle threshold.

[0053] In an embodiment, it is determined whether the vehicle meets the conditions for the launch control ready mode, that is, it is determined whether the driving state of the vehicle is in a state of waiting to drive, and it is determined whether the time since the vehicle last exited the launch control ready mode is greater than or equal to a second preset time. For example, it is determined whether the time since the vehicle last exited the launch control ready mode is greater than or equal to 10 seconds; and it is determined whether the time since the vehicle last exited the launch mode is greater than or equal to a third preset time. For example, it is determined whether the time since the vehicle last exited the launch mode is greater than or equal to 10 seconds, where the time since the vehicle last exited the launch control ready mode and the time since the vehicle last exited the launch mode can be calibrated according to the actual situation; and it is determined whether the maximum available torque of the vehicle's power system is greater than a preset torque threshold, and whether the maximum available power of the power system is greater than a preset power threshold, where the preset torque threshold is denoted as Ta for example, and the preset power threshold is denoted as Pa for example; and it is determined whether there is no fault of a preset type in the power system. For example, it is determined whether there is no fault that affects the power output ability in the power system; and it is determined whether the vehicle speed is less than a preset speed threshold. For example, it is determined whether the vehicle speed value is less than 100 Kph; and it is determined whether the brake pedal of the vehicle is depressed and the braking force is greater than a preset braking force threshold; and it is determined whether the vehicle is in a preset gear. For example, it is determined whether the vehicle gear is in the forward gear; and it is determined whether the depth of the accelerator pedal of the vehicle is greater than a preset depth threshold, and it is determined whether the driving mode of the vehicle is in a set driving mode. For example, it is in the sports mode or a mode with sports attributes; and it is determined whether the steering angle of the vehicle's steering wheel is less than a preset angle threshold. If all the above conditions are met, it is considered that the vehicle meets the conditions for entering the launch control ready mode, and the vehicle is controlled to enter the launch control ready mode. By setting multiple conditions to determine the conditions for the vehicle to enter the launch control ready mode, it is possible to prevent the vehicle from mistakenly entering the launch control ready mode, so as to improve the accuracy of the vehicle entering the launch control ready mode.

[0054] In some embodiments, the vehicle launch control method further includes: when it is confirmed that the vehicle meets the conditions for exiting the launch control ready mode, controlling the vehicle to exit the launch control ready mode.

[0055] In an embodiment, by determining whether the vehicle meets the conditions for exiting the launch control ready mode, the running state of the vehicle during the exit is controlled. When it is determined that the vehicle meets the conditions for exiting the launch control ready mode, the vehicle is controlled to exit the launch control ready mode.

[0056] In some embodiments, the conditions for exiting the launch control ready mode include: the vehicle is not in a ready-to-drive state; or, the time for the vehicle to enter the launch control ready mode is greater than or equal to a fourth preset time; or, the maximum available torque of the vehicle's powertrain is less than or equal to a preset torque threshold, and the maximum available power of the powertrain is less than or equal to a preset power threshold; or, there is a preset type of fault in the vehicle's powertrain; or, the vehicle speed is greater than or equal to a preset speed threshold; or, the vehicle is not in a preset gear; or, the depth of the vehicle's accelerator pedal is less than or equal to a preset depth threshold; or, the vehicle's driving mode is not in a set driving mode; or, the vehicle's brake pedal is not depressed and the braking force is less than a preset braking force threshold.

[0057] In an embodiment, when determining whether the vehicle meets the conditions for the launch control ready mode, it is necessary to determine whether the vehicle is in a ready-to-drive state, or determine whether the time for the vehicle to enter the launch control ready mode is greater than or equal to a fourth preset time, for example, determine whether the time for the vehicle to enter the launch control ready mode is greater than or equal to 10 seconds; or, determine whether the maximum available torque of the vehicle's powertrain is less than or equal to a preset torque threshold Ta and whether the maximum available power of the powertrain is less than or equal to a preset power threshold Pa, or determine whether there is a preset type of fault in the vehicle's powertrain, or determine whether the vehicle speed is greater than or equal to a preset speed threshold of 100 kph, or determine whether the vehicle is not in a preset gear, for example, whether it is not in the forward gear; or, determine whether the depth of the vehicle's accelerator pedal is less than or equal to a preset depth threshold, for example, less than or equal to a preset depth threshold Aa; or, determine whether the vehicle's driving mode is not in a set driving mode, or determine whether the vehicle's brake pedal is not depressed and the braking force is less than a preset braking force threshold Ba. It can be understood that the above-mentioned preset time, preset torque threshold, preset depth threshold, and preset braking force threshold can all be calibrated according to the actual situation. If one or several of the above conditions are met, it is considered that the vehicle meets the conditions for exiting the launch control ready mode. By setting multiple conditions to determine the conditions for the vehicle to exit the launch control ready mode, the accuracy of the vehicle exiting the launch control ready mode can be improved.

[0058] In some embodiments, the vehicle launch control method further includes: when it is confirmed that the vehicle meets the conditions for exiting the launch control mode, controlling the vehicle to exit the launch control mode.

[0059] In some embodiments, the conditions for exiting the launch control ready mode include: the vehicle is not in a ready-to-drive state; or, there is a preset type of fault in the vehicle's powertrain; or, the vehicle speed is greater than or equal to a preset speed threshold; or, the vehicle is not in a preset gear; or, the depth of the vehicle's accelerator pedal is less than or equal to a preset depth threshold; or, the vehicle's driving mode is not in a set driving mode.

[0060] For example, by determining whether the vehicle is in a standby driving state, or determining whether there is a preset type of fault in the vehicle's power system, or determining whether the vehicle speed is greater than or equal to a preset speed threshold, or determining whether the vehicle is not in a preset gear, or determining whether the depth of the vehicle's accelerator pedal is less than or equal to a preset depth threshold, or determining whether the vehicle's driving mode is not in a set driving state, if any of the above conditions is met, the vehicle is controlled to exit the launch control mode.

[0061] In some embodiments, the conditions for entering the launch control mode include: the vehicle has entered the launch control preparation mode, and the vehicle's brake pedal is not depressed and the braking force is less than a preset braking force threshold. Specifically, after determining that the vehicle has entered the launch control preparation mode, the state and braking force of the vehicle's brake pedal are detected. If the vehicle's brake pedal is not depressed and the braking force is less than the preset braking force threshold, the vehicle is controlled to enter the launch control mode.

[0062] In some embodiments, after the vehicle exits the launch control preparation mode, it further includes: turning off the torque oscillation random generator. It can be understood that after the vehicle exits the launch control preparation mode, the torque oscillation random generator is controlled to turn off so that the vehicle can normally enter the launch control mode.

[0063] In some embodiments, after activating the vehicle's torque oscillation random generator, it further includes: sending a prompt message indicating that the torque oscillation random generator has been activated. Specifically, after the launch control preparation mode is activated, a display window or an icon pops up on the instrument panel to remind the driver that the torque random generator has been activated.

[0064] According to the vehicle launch control method of the embodiments of the present invention, when a launch command is received, it is determined whether the vehicle meets the conditions for entering the launch control preparation mode. When it is determined that the vehicle meets the conditions for entering the launch control preparation mode, the vehicle is controlled to enter the launch control preparation mode, and the vehicle's torque oscillation random generator is activated to randomly generate oscillating torque, giving the vehicle a strong personality, so that the vehicle has richer performance during the launch control preparation stage, enhancing the communication between the driver and the vehicle, improving the driving pleasure, and at the same time improving the user experience.

[0065] The following describes a vehicle launch control device according to an embodiment of the present invention in conjunction with the accompanying drawings.

Among them, the first judgment module 20 is used to judge whether the vehicle meets the conditions for entering the catapult start preparation mode when receiving a catapult start instruction; the activation module 21 is used to control the vehicle to enter the catapult start preparation mode when the vehicle meets the conditions for entering the catapult start preparation mode, so as to activate the torque oscillation random generator of the vehicle, and the torque oscillation random generator randomly outputs a plurality of oscillation torques with random durations within a preset torque range; the second judgment module 22 is used to judge whether the vehicle meets the conditions for entering the catapult start mode; the control module 23 is used to control the vehicle to enter the catapult start mode when the vehicle meets the conditions for entering the catapult start mode, so as to control the power system of the vehicle to operate at the current maximum output torque.

[0068] In some embodiments, the activation module 21 is specifically used to obtain the remaining power of the vehicle battery system, and control the torque oscillation random generator to randomly output a plurality of oscillation torques with random durations within the torque range of the maximum oscillation torque and the minimum oscillation torque. Among them, when the remaining power is less than the preset power, the maximum oscillation torque and the minimum oscillation torque are respectively less than the preset maximum oscillation torque and the preset minimum oscillation torque corresponding to the preset power.
