For example, object features, interactive behavior features, user information, and the like referred to in this specification are all acquired with sufficient authorization.

In the embodiment of the application, the vehicle performing the vehicle starting method is a hybrid vehicle, that is, a vehicle having a hybrid system and having data processing and transmitting capabilities. As shown in fig. 1, a schematic structural diagram of a hybrid vehicle according to an embodiment of the present application is provided, and the hybrid vehicle 101 includes at least a front axle portion 1011 and a rear axle portion 1012.

Front axle portion 1011 may include an engine 102 and an electric machine 103, with the engine 102 and electric machine 103 being coupled by a clutch and other electrical and/or mechanical devices. The rear axle portion 1012 may include the motor 104, and the vehicle 101 may further include the battery module 105 therein, wherein the battery module 105 includes a storage battery rated at 12V and a power battery rated at 350V to 420V. The motor 102, the motor 103, the motor 104 and the battery module 105 are connected by electrical and/or mechanical means, not shown in fig. 1.

It is to be understood that the configuration of the hybrid vehicle shown in fig. 1 is merely illustrative, and the present application may also include hybrid vehicles of other configurations. For example, the front axle portion 1011 may also include a gearbox, the electric motor 103 being connected to an input shaft of the gearbox, the gearbox 211 may be of the type of an electro-mechanical automatic transmission (Automated Mechanical Transmission, AMT) gearbox, and a synchronizer may be provided therein to effect synchronous shifting of the front axle through the gearbox provided with the synchronizer.

Thus, based on the hybrid powertrain, the vehicle 101 may be configured under different drive strategies. The driving strategy comprises a driving mode and an operating mode, wherein the driving mode at least comprises one of the following modes: the working modes comprise at least one of the following modes: electric only operation, series operation, direct drive operation and electric idle operation EV idle.

Specifically, the different drive modes are different in the portions that provide the driving force to the vehicle. The motor 103 of the front axle portion 1011 of the vehicle 101 provides driving force for the vehicle 101 in the front drive mode, the motor 104 of the rear axle portion 1012 of the vehicle 101 provides driving force for the vehicle 101 in the rear drive mode, and the motor 103 of the front axle portion 1011 and the motor 104 of the rear axle portion 1012 simultaneously provide driving force for the vehicle 101 in the four drive mode. And different modes of operation correspond to different sources of power providing torque. When the vehicle 101 is operating on electric only, a source of power is provided by the electric machine 103 and/or the electric machine 104. When the vehicle 101 is operated based on series, the motor 103 is driven by the engine 102 and the generated electrical energy can charge the power battery. When the vehicle is operated based on direct drive, the engine 102 may directly drive the front axle portion 1011 of the vehicle 101 through the transmission to run the vehicle 101. When the vehicle 101 operates EV idle based on electric idle, the engine is stopped, and the vehicle is driven to run by the motor 103 and/or the motor 104.

While the vehicle is traveling, the engine needs to be started to meet the vehicle traveling demand based on the user's instructions or other sources. For example, when the vehicle passes a special road section (such as snow, water accumulation road section, etc.) and requires more driving stability, or when the user wants the vehicle to perform four-Wheel power output to improve acceleration performance, the user sets the driving strategy to All-Wheel Drive full-time four-Wheel Drive, for the structure of the hybrid vehicle, especially the single clutch vehicle, the engine is started to realize the switching process from the first strategy mode to the second strategy mode, the problem of power delay caused by starting the re-shift Drive operation due to the off-neutral gear exists, and the risk of vehicle slipping during the switching process of the four-Wheel Drive mode to the rear Drive mode may also occur.

Accordingly, the embodiments of the present application provide a vehicle starting method based on the above-mentioned problems to solve some or all of the above-mentioned problems. In one embodiment, as shown in fig. 2, a flow diagram of a vehicle starting method according to an embodiment of the present application is provided, which may be implemented by a computer program and may be executed on a von neumann system-based vehicle starting apparatus. The computer program may be integrated in the application or may run as a stand-alone tool class application.

Specifically, the vehicle starting method includes:

s101, receiving a starting instruction, wherein the starting instruction is used for indicating to switch the vehicle from a first driving strategy to a second driving strategy requiring engine driving.

The vehicle is driven or parked based on a first drive strategy, e.g., the first drive strategy is a lead mode and is operating purely electrically. The start command is used to instruct switching the vehicle from the first drive strategy to a second drive strategy requiring engine drive, e.g., the second drive strategy is in a four-drive mode and is operated at electric idle, the second drive strategy requiring engine start.

In one embodiment, the initiation instructions may be from a user. As shown in fig. 3, fig. 3 is a schematic view of a scenario in which a vehicle-mounted display receives a start command according to an embodiment of the present application. The vehicle is provided with a display 201, and the surface of the display 201 is a transparent glass substrate or a transparent flexible substrate and has a function of interacting with a user. For example, the user may input a switching instruction for switching the driving strategy to the display 201 by means of touch, remote control, voice, gesture remote control, or the like, the switching instruction being for instructing to switch the vehicle from the first driving strategy to the second driving strategy requiring engine driving. Further, when the processor determines that the switching instruction is valid based on the running parameter of the vehicle, a start instruction to start the engine is generated in response to the switching instruction. For example, the driving parameters include a gear of the vehicle, a driving environment, a driving state, and the like.

Specifically, as shown in fig. 3, a plurality of display controls such as a map, a music playing, a driving speed, a driving mode, and the like are displayed on the display 201, and a user touches a target control on the display 201 by clicking, sliding, or the like, so that the display 201 receives an instruction corresponding to the target control. In this embodiment, the user touches the display control at the upper right and lower corners of the display 201, so that the processor of the vehicle receives a switching instruction through the display 201, and the content of the switching instruction is that the vehicle switches from the first driving strategy to the second driving strategy requiring engine driving, and the processor determines that the switching instruction is valid based on the driving parameters of the vehicle, and generates a start instruction for starting the engine in response to the switching instruction.

In another embodiment, the start command may also be received by detecting a trigger of a preset condition. For example, the vehicle is determined to be driven into a special road section through the camera device or the radar sensor, the special road section comprises a snow covered road section, a water accumulated road section or a hollow street lamp, or the vehicle is determined to be accelerated to overtake and change the road through the intelligent driving system, a starting instruction in the storage unit is received, and the content of the starting instruction is that the vehicle is switched from a first driving strategy to a second driving strategy needing engine driving.

S102, responding to a starting instruction, and determining a target starting mode of the engine according to the speed of the vehicle, the first driving strategy and the second driving strategy.

The engine is started in at least one of the following modes: the engine is started by a 12V starter, and is driven by a motor to quickly start and slide and rub. The slip start can be understood as the need to start the engine by using the clutch slip action, that is, the actual torque of the clutch is used to boost the motor compensation, so as to ensure the smoothness of the engine starting process.

In the embodiment of the application, a target starting mode of the engine is determined according to the speed of the vehicle, the first driving strategy and the second driving strategy. Specifically, in response to a start instruction, a vehicle speed of the vehicle is acquired; judging whether the vehicle speed is within a preset range or not; and when the vehicle speed is in a preset range, determining a target starting mode of the engine according to the first driving strategy and the second driving strategy. For example, the first driving strategy is in a precursor mode and purely electric operation, the second driving strategy is in a four-drive mode and works in an electric idle speed, the second driving strategy needs to start the engine, the speed of the vehicle, the first driving strategy and the second driving strategy are obtained according to a starting instruction, whether the speed is in a preset range is further judged, and accordingly a target starting mode is primarily determined according to the speed, and further the target starting mode is determined according to contents corresponding to the first driving strategy and the second driving strategy.

S103, starting the engine according to a target starting mode.

And starting the engine of the vehicle according to the target starting mode. For example, the second strategy mode is a four-wheel drive mode and works in direct drive, the target starting mode is a sliding friction starting mode, and the process of starting the engine according to the target starting mode includes: the gearbox controller controls the clutch to be opened according to the torque unloading conditions at the two ends of the clutch, and controls the gearbox to be switched to a target gear corresponding to the direct drive mode; further, the gearbox controller charges the clutch with oil, and sends a clutch slipping state signal to the vehicle controller so that the vehicle controller increases the front axle end torque request, compensates the driving loss caused by starting the engine by slipping of the clutch, and sends the increased front axle end torque request to the gearbox controller; further, the gearbox controller further controls the clutch to be closed according to the rotating speed difference condition of the two ends of the clutch, and sends a torque recovery request to the vehicle controller, so that the vehicle controller responds to the torque recovery request to control the torque recovery of the two ends of the clutch, and the switching process of the direct drive mode is completed.

In one embodiment, as shown in fig. 4, a flow diagram of a vehicle starting method according to an embodiment of the present application is provided, which may be implemented by a computer program and may be executed on a von neumann system-based vehicle starting apparatus. The computer program may be integrated in the application or may run as a stand-alone tool class application.

Specifically, the vehicle starting method includes:

s201, receiving a starting instruction, wherein the starting instruction is used for indicating to switch the vehicle from a first driving strategy to a second driving strategy requiring engine driving.

See S101 above, and will not be described here again.

S202, responding to a starting instruction, and acquiring the speed of the vehicle.

The start instruction may be from a user, or may be triggered by detecting a preset condition. As shown in fig. 3, fig. 3 is a schematic view of a scenario in which a vehicle-mounted display receives a start command according to an embodiment of the present application.

And responding to the starting instruction, and acquiring the speed of the vehicle through a speed acquisition module of the vehicle. The speed acquisition module can be a module formed by at least one component such as a gyroscope, a pulse sensor, a radar, a brake control unit and the like, and the controller acquires the current speed of the vehicle through the speed acquisition module, wherein the unit of the speed can be km/h.

S203, judging whether the vehicle speed is within the preset range?

The preset range is a vehicle speed protection range corresponding to the first driving strategy in the precursor mode and the pure electric operation and the second driving mode in the direct driving operation. In other words, when the vehicle is switched from the front drive mode and the electric-only operation, that is, the driving state in which the drive force is supplied from the front axle portion and the power source is supplied from the electric-only motor, to the driving state in which the engine directly supplies the power source to the vehicle through the transmission, the corresponding protection vehicle speed range is switched. For example, the preset range is 30km/h to 80km/h. Of course, the set values in the preset range may also be other values, for example, 20km/h to 80km/h, 30km/h to 90km/h, 30km/h to 100km/h, etc., and are set as required, which is not limited in any way in the embodiment of the present application.

S204, when the vehicle speed is within the preset range, judging whether the vehicle meets the condition that the second driving strategy is direct driving operation?

The direct drive operating condition may be a load condition and a road condition of the vehicle. For example, when the vehicle is in a running state of a large angle hill climbing, or the load of the vehicle approaches a load threshold value, the vehicle does not satisfy the condition of the direct-drive operation. When the vehicle does not meet the condition of direct drive operation, the second driving strategy is electric idle operation or series operation, namely, the vehicle is driven by the transmitter and the motor in a coordinated manner to run based on the second driving strategy. In other embodiments, the conditions of the direct drive operation may be other, as set by the driver or associated technician as desired.

S205, if the vehicle speed is in a preset range and the vehicle meets the condition that the second driving strategy is direct-drive operation, determining a target starting mode of the engine according to the first driving strategy.

When the vehicle meets the condition of direct-drive operation, namely, the vehicle can run based on the second drive strategy of the direct-drive operation, the target starting mode of the engine is further determined according to the specific content of the first drive strategy. For example, when the second driving strategy is in the direct-drive mode and the four-drive mode, an appropriate target start mode is selected to start the engine according to the states of the clutches corresponding to the first driving strategy in the forward-drive mode or the rear-drive mode and the pure electric mode, respectively.

For example, the clutch may be initially activated in a slip-on manner to avoid engine stall or rapid vehicle speed rise caused by direct clutch closure. Further, when the clutch is started and operated in the slip state, the vehicle speed and the rotational speed of the engine may be controlled to gradually increase to a proper range, and then the clutch may be closed until the vehicle runs based on the second driving strategy.

S206, when the vehicle speed is not in the preset range, determining that the target starting mode of the engine is 12V starter starting.

When the vehicle is lower than the preset range or higher than the preset range, the target starting mode of the transmitter is determined to be 12V starter starting. For example, the preset range is 30km/h to 80km/h, and when the vehicle speed is lower than the preset range or higher than the preset range, the engine is started by means of a 12V starter in response to a start command.

In one embodiment, as shown in fig. 5, a flow diagram of a vehicle starting method according to an embodiment of the present application is provided, which may be implemented by a computer program and may be executed on a von neumann system-based vehicle starting apparatus. The computer program may be integrated in the application or may run as a stand-alone tool class application.

Specifically, the vehicle starting method includes:

s301, receiving a starting instruction, wherein the starting instruction is used for indicating to switch the vehicle from a first driving strategy to a second driving strategy requiring engine driving.

See S101 above, and will not be described here again.

S302, responding to a starting instruction, and acquiring the speed of the vehicle.

See S202 above, and will not be described here again.

S303, judging whether the vehicle speed is within a preset range?

See S203 above, and will not be described here again.

S304, when the vehicle speed is within the preset range, judging whether the vehicle meets the condition that the second driving strategy is direct driving operation?

See S204 above, and will not be described again here.

S305, if the vehicle speed is in a preset range and the vehicle meets the condition that the second driving strategy is in direct driving operation, determining that the target starting mode of the engine is sliding friction starting according to the fact that the first driving strategy is in a four-wheel driving mode and in pure electric operation.

If the vehicle speed is within the preset range, the specific content of the first driving strategy is obtained in response to the starting instruction, and when the first driving strategy is in a four-drive mode and operated in a pure electric mode and the second driving strategy is operated in a direct drive mode, for example, the second driving strategy is in the four-drive mode and operated in the direct drive mode, the target starting mode of the engine is determined to be the sliding friction starting mode. The controller of the vehicle can send a signal for starting the sliding friction to the clutch and the engine so as to control the sliding friction of the engine to start until the engine becomes a power source of the vehicle, and the requirement of the vehicle on the basis of the second driving strategy is met.

S306, if the vehicle speed is within a preset range, but the vehicle does not meet the condition that the second driving strategy is in direct driving operation, determining that the target starting mode of the engine is 12V starter starting according to the fact that the first driving strategy is in a four-drive mode or a rear-drive mode and the first driving strategy is in pure electric operation.

The conditions of the direct drive operation may be the load condition and road condition of the vehicle. For example, when the vehicle is in a running state of a large angle hill climbing, or the load of the vehicle approaches a load threshold value, the vehicle does not satisfy the condition of the direct-drive operation. When the first driving strategy is in the four-wheel drive mode or the rear-wheel drive mode and is in the pure electric operation, the first driving strategy is switched to the second driving strategy in the four-wheel drive mode and the direct-wheel drive mode, and only the front axle part and the engine of the vehicle are required to be started, so that a target starting mode of starting the 12V starter is adopted.

In this embodiment, the first driving strategy is a rear-drive mode and a pure electric mode, and to switch to the front-drive mode and the direct-drive mode, the gear shifting of the front axle portion and the starting of the engine can be performed synchronously, so that the switching efficiency from the first driving mode to the second driving mode is improved, and the switching time is saved.

S307, when the vehicle speed is not in the preset range, determining that the target starting mode of the engine is 12V starter starting.

See S206 above, and will not be described here again.

S308, determining whether the vehicle satisfies the condition that the second driving strategy is the electric idle operation?

After the target starting mode of the engine is determined, the engine is started according to the target starting mode, so that the vehicle runs based on the second driving strategy. The start instruction of the user may set the driving mode of the second driving strategy, for example, the driving mode of the second driving strategy is a four-wheel-drive mode, and the working mode of the second driving strategy is determined by the state of the vehicle.

In the embodiment of the application, the condition of the electric idle operation is that the electric quantity of the vehicle is higher than the electric quantity threshold value. The charge level may refer to a feed state of the vehicle, i.e., a battery under-charge characteristic of the vehicle when the charge level of the vehicle is below a charge level threshold. When the vehicle is in a running state, if the battery electric quantity is smaller than or equal to the electric quantity threshold value, the battery electric quantity is indicated to be incapable of meeting the running requirement of the electric idle operation. For example, the charge threshold may refer to 20% of the battery charge, 30% of the battery charge, or the like. The power threshold may also be set according to the capacity of the battery, for example, when the capacity of the battery is relatively large, the power threshold may refer to 10% of the battery power, even 5% of the battery capacity, and when the capacity of the battery is relatively small, the power threshold may refer to 30% or 40% of the battery power, or the like. It will be appreciated that the above description of "power threshold" is merely illustrative, and the present embodiment is not limited in any way.

S309, when the vehicle meets the condition that the second driving strategy is the electric idle operation, starting the engine according to the target starting mode, and controlling the vehicle to run based on the second driving strategy of the electric idle operation.

When the vehicle meets the condition that the second driving strategy is electric idle operation, the controller starts the engine according to a target starting mode of starting or sliding friction starting of the 12V starter, and sends working instructions of the electric idle operation to the engine and the motor respectively so that the vehicle runs based on the second driving strategy of the electric idle operation.

And S310, when the vehicle does not meet the condition that the second driving strategy is the electric idle operation, starting the engine according to the target starting mode, and controlling the vehicle to run based on the second driving strategy of the series operation or the direct driving operation.

When the vehicle does not meet the condition that the second driving strategy is the electric idle operation, for example, the battery level of the vehicle is lower than a battery level threshold, the controller sends a charging instruction to the motor and sends a driving instruction to the engine so as to realize the control of the vehicle to run based on the second driving strategy of the series operation. Or, the controller sends a driving instruction to the engine to control the cutoff member and the gear shifting member of the hybrid power device to be disconnected so as to control the vehicle to run in a second strategy mode based on the direct driving operation of the engine direct driving vehicle.

The start-stop task includes a plurality of timings including starting the engine, and specifically, the start-stop process should be run at a start-up preparation-drag phase-request ignition-torque architecture activation-normal operation-stop preparation-stop command-stop completion timing. In other words, the start-stop task includes a plurality of timings, and the start of the engine is completed in the target timing of the start-stop task. It is understood that the following timing does not include the timing of the shutdown preparation and the timings after the timing.

When the vehicle meets the condition that the second driving strategy is electric idle operation, starting the engine according to a target starting mode in a target time sequence of a start-stop task, and after the time for starting the engine reaches a preset time length, continuing to execute the next time sequence from the target time sequence, and controlling the vehicle to run based on the second driving strategy of the electric idle operation until all time sequences of the start-stop task are completed. In other words, when the vehicle is switched to the second driving strategy of the electric idle operation for driving, whether the clutch is closed or not is not needed to be detected in the target time sequence of the start-stop task, and when the time for starting the engine only reaches the preset time length, the target time sequence for activating the torque framework is determined to be completed, the next time sequence is continuously executed, and the start-stop task is finally completed.

When the vehicle does not meet the condition that the second driving strategy is the electric idle operation, starting the engine according to a target starting mode in a target time sequence, and detecting whether a clutch of the vehicle is closed or not; and after the clutch is closed, continuously executing the next time sequence from the target time sequence, and controlling the vehicle to run based on a second driving strategy of series operation or direct driving operation until all time sequences of start-stop tasks are completed. In other words, when the vehicle is switched to run with the second driving strategy of the series operation or the direct driving operation, whether the clutch is closed needs to be detected in the target time sequence of the start-stop task, and only when the clutch is closed, the clutch is considered to normally transmit torque to the front axle part or the rear axle part, the target time sequence of the activation of the torque framework is determined to be completed, the next time sequence is continuously executed, and the start-stop task is finally completed.

According to the embodiment, based on the difference of the working modes in the second driving strategy, the execution contents of different target time sequences are respectively set in the start-stop tasks of the engine, so that time is saved, and the execution efficiency of the start-stop tasks is improved.

In one embodiment, as shown in fig. 6, a flow diagram of a vehicle starting method according to an embodiment of the present application is provided, which may be implemented by a computer program and may be executed on a von neumann system-based vehicle starting apparatus. The computer program may be integrated in the application or may run as a stand-alone tool class application.

Specifically, the vehicle starting method includes:
