Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a control method for powering on and off a vehicle and an intelligent driving vehicle. Background Technology

[0002] As the application of intelligent driving vehicles becomes more and more widespread, people's requirements for the safety and reliability of intelligent driving vehicles are also increasing.

[0003] The control logic for power-on or power-off operations of existing intelligent driving vehicles is relatively complex. Furthermore, the power-on or power-off operations of intelligent driving are coupled in both autonomous and non-autonomous driving (i.e., manual driving), making the operation cumbersome and thus failing to guarantee the safety and reliability of vehicle power-on or power-off. Summary of the Invention

[0004] This invention provides a control method for powering on and off a vehicle and an intelligent driving vehicle, enabling the vehicle to independently perform power-on or power-off operations under autonomous or non-autonomous driving conditions, ensuring the safety and reliability of powering on and off the vehicle.

[0005] In a first aspect, embodiments of the present invention provide a method for controlling the power on / off of a vehicle, comprising:

[0006] Obtain a first external command, and determine whether the vehicle should trigger autonomous driving based on the first external command;

[0007] After determining that the vehicle has not triggered autonomous driving and meets the first preset condition, a second external command is obtained, and the vehicle is powered on or off according to the second external command;

[0008] After determining that the vehicle has triggered autonomous driving and met the second preset condition, a third external command is obtained, and the vehicle is powered on or off according to the third external command.

[0009] Optionally, the first preset condition includes:

[0010] Once it is determined that the vehicle has not triggered autonomous driving, a timer is started, and the timer continues until a preset time is reached.

[0011] Optionally, before obtaining a third external command and after determining that the vehicle has triggered autonomous driving, the process includes:

[0012] Obtain driving mode information and determine the current driving mode of the vehicle based on the driving mode information, wherein the driving mode information includes automatic driving and manual driving;

[0013] The second preset condition includes: determining that the current driving mode of the vehicle is automatic driving mode based on the driving mode information.

[0014] Optionally, the control method further includes:

[0015] When the current driving mode of the vehicle is determined to be manual driving mode based on the driving mode information, it is further determined whether the ON relay is closed, wherein the closed ON relay indicates that the vehicle is in a powered-on state;

[0016] When the ON relay is determined to be closed, the vehicle is controlled to remain powered on or off according to the second external command.

[0017] Optionally, the control method further includes:

[0018] If it is determined that the ON relay is not closed, continue to determine whether the vehicle is stationary;

[0019] If the vehicle is stationary, the vehicle is powered off according to the third external command;

[0020] If the vehicle is in motion, the vehicle is powered on according to the second external command.

[0021] Optionally, before obtaining driving mode information, the following may also be included:

[0022] Determine if the vehicle is malfunctioning;

[0023] If the vehicle malfunctions, the second external command is obtained, and the vehicle is powered on according to the second external command;

[0024] If the vehicle is not malfunctioning, continue acquiring driving mode information.

[0025] Optionally, the vehicle malfunction includes the failure of the autonomous driving mode.

[0026] Optionally, before obtaining the first external instruction, the following may be included:

[0027] Determine whether the vehicle is in an emergency stop state;

[0028] If the vehicle is in an emergency stop state, the second external command is obtained, and the vehicle is powered on according to the second external command;

[0029] If the vehicle is not in an emergency stop state, it continues to acquire the first external command.

[0030] Optionally, the first external command includes a switching command for the driving mode switch;

[0031] The second external command includes a key switching command;

[0032] The third external instruction includes control instructions issued by the host computer.

[0033] Secondly, embodiments of the present invention provide an intelligent driving vehicle, including a drive-by-wire chassis device, the drive-by-wire chassis device being used to control the driving of the intelligent driving vehicle;

[0034] The drive-by-wire chassis device includes a body controller for executing the vehicle power-on / off control method as described in the first aspect, so as to perform power-on or power-off operations on the intelligent driving vehicle.

[0035] The technical solution provided in this embodiment obtains a first external command and determines whether the vehicle has triggered autonomous driving. If it is determined that the vehicle has not triggered autonomous driving, the vehicle triggers manual driving. After meeting a first preset condition, a second external command is obtained, and the vehicle is powered on or off according to the second external command to ensure normal operation. When it is determined that the vehicle has triggered autonomous driving and the second preset condition is met, the vehicle can be powered on or off according to the obtained third external command. In this way, the vehicle can independently perform power-on or power-off operations in both autonomous and non-autonomous driving (i.e., manual driving) modes, ensuring the safety and reliability of power-on and power-off.

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this invention. Obviously, the described embodiments are only some embodiments of this invention, not all embodiments. Based on the basic concepts disclosed and indicated in the embodiments of this invention, all other embodiments obtained by those skilled in the art are within the scope of protection of this invention.

[0046] Figure 1 A flowchart of a vehicle power-on / off control method provided in an embodiment of the present invention is shown below. Figure 1 As shown, the control method includes:

[0047] S101. Obtain the first external command and determine whether the vehicle has triggered autonomous driving based on the first external command.

[0048] The first external command includes a driving mode switching command. It's understood that a driving mode switching button is typically located in the vehicle's driver's compartment. Pressing this button triggers the vehicle to enter autonomous driving mode, while pressing it puts the vehicle into manual driving mode. Thus, upon receiving the first external command, the vehicle's body controller within the drive-by-wire chassis can determine whether the vehicle has activated autonomous driving based on the specific status value (e.g., a digital signal value) corresponding to the command.

[0049] S102. After determining that the vehicle has not triggered autonomous driving and the first preset condition is met, a second external command is obtained, and the vehicle is powered on or off according to the second external command.

[0050] Among them, the second external command includes the key switch command. It is understood that the power-on mode of existing vehicles all include key power-on, and its priority is often higher than other power-on modes (such as voice control power-on or remote power-on). Key power-on is safer and more reliable than other power-on modes, thus ensuring the reliability of vehicle power-on.

[0051] Specifically, if it is determined that the vehicle has not triggered autonomous driving, it can be considered that the vehicle has triggered manual driving. After the vehicle enters manual driving, the power on or off of the vehicle can be controlled by obtaining the key's switch command to ensure the normal power on and off of the vehicle.

[0052] S103. After determining that the vehicle has triggered autonomous driving and met the second preset conditions, obtain the third external command and control the vehicle to power on or off according to the third external command.

[0053] Among them, the third external command includes control commands issued by the host computer. It can be understood that the host computer and the body controller in the drive-by-wire chassis can communicate, which can be wired or wireless communication, without specific limitations. In this way, the host computer can issue power-on or power-off control commands according to actual needs to control the vehicle to perform power-on or power-off operations.

[0054] In this embodiment, by acquiring a first external command, it can be determined whether the vehicle has triggered autonomous driving. If it is determined that the vehicle has not triggered autonomous driving, the vehicle will engage manual driving. After meeting a first preset condition, a second external command will be acquired, and the vehicle will be powered on or off according to the second external command to ensure normal operation of the vehicle. When it is determined that the vehicle has triggered autonomous driving and the second preset condition is met, the vehicle can be powered on or off according to the acquired third external command. In this way, the vehicle can independently perform power-on or power-off operations in both autonomous and non-autonomous driving (i.e., manual driving) modes, ensuring the reliability of vehicle power-on and power-off.

[0055] Optional, Figure 2 A flowchart of the second vehicle power-on / off control method provided in the embodiments of the present invention is shown below. Figure 2 As shown, the first preset condition includes: after determining that the vehicle has not triggered autonomous driving, timing begins and the timing time reaches the preset time.

[0056] The specific value of the preset time can be set according to actual needs, and the embodiments of the present invention do not impose specific limitations on it.

[0057] refer to Figure 2 As shown, in Figure 1 Based on this, step S102 specifically includes the following steps:

[0058] S1021. After determining that the vehicle has not triggered autonomous driving, start timing and keep timing until the preset time is reached.

[0059] S1022. Obtain a second external command and control the vehicle to power on or off according to the second external command.

[0060] Specifically, after the vehicle's autonomous driving function is not activated, the timing module in the body controller begins timing. Once the preset time has elapsed, a second external command is received, and the vehicle's power is switched on or off based on this command. This avoids the first external command being caused by a false trigger or interference signal, allowing the driver to make timely corrections before powering the vehicle on or off, thus ensuring the vehicle's safety and reliability.

[0061] Optional, Figure 3 A flowchart of the third vehicle power-on / off control method provided in the embodiments of the present invention is shown below. Figure 3 As shown, in Figure 1 Based on this, before obtaining a third external command and after determining that the vehicle has triggered autonomous driving, the method includes: before obtaining the third external command, obtaining driving mode information and determining the current driving mode of the vehicle based on the driving mode information, whereby the driving mode information includes autonomous driving and manual driving; the second preset condition includes: determining that the current driving mode of the vehicle is autonomous driving mode based on the driving mode information. Therefore, this control method specifically includes the following steps:

[0062] S301. Obtain the first external command and determine whether the vehicle has triggered autonomous driving based on the first external command.

[0063] S302. After determining that the vehicle has not triggered autonomous driving and the first preset condition is met, a second external command is obtained, and the vehicle is powered on or off according to the second external command.

[0064] S303. After determining that the vehicle has triggered autonomous driving, obtain driving mode information and determine the current driving mode of the vehicle based on the driving mode information.

[0065] The driving mode information includes both automatic and manual driving.

[0066] S304. Based on the driving mode information, determine that the current driving mode of the vehicle is automatic driving mode, obtain third external commands, and control the vehicle to power on or off according to the third external commands.

[0067] Specifically, after the vehicle controller triggers autonomous driving based on the first external command received, the vehicle is allowed to drive autonomously. However, this does not mean that the controllers in the entire vehicle have been adjusted to the autonomous driving control mode. The vehicle controller needs to further obtain driving mode information and determine whether the current driving mode of the vehicle is autonomous driving based on the driving information. Only when the current driving mode of the vehicle is autonomous driving will it continue to obtain a third external command, such as a control command received from the host computer in autonomous driving mode. Then, the vehicle is powered on or off according to the third external command. This allows the vehicle to be powered on or off through the control commands of the host computer or remote terminal devices while in autonomous driving mode, thereby improving the vehicle's intelligence.

[0068] Optional, Figure 4 A flowchart of the fourth vehicle power-on / off control method provided in the embodiments of the present invention is shown below. Figure 4 As shown, in Figure 3 Based on this, the method further includes: when determining that the vehicle's current driving mode is manual driving mode based on driving mode information, further determining whether the ON relay is closed, wherein a closed ON relay indicates that the vehicle is powered on; when the ON relay is determined to be closed, then controlling the vehicle to maintain the powered-on state or de-energize it according to a second external command. Therefore, this control method specifically includes the following steps:

[0069] S401. Obtain the first external command and determine whether the vehicle has triggered autonomous driving based on the first external command.

[0070] S402. After determining that the vehicle has not triggered autonomous driving and the first preset condition is met, a second external command is obtained, and the vehicle is powered on or off according to the second external command.

[0071] S403. After determining that the vehicle has triggered autonomous driving, obtain driving mode information and determine the current driving mode of the vehicle based on the driving mode information.

[0072] The driving mode information includes both automatic and manual driving.

[0073] S404. Based on the driving mode information, determine that the current driving mode of the vehicle is automatic driving mode, obtain third external commands, and control the vehicle to power on or off according to the third external commands.

[0074] S405. When the current driving mode of the vehicle is determined to be manual driving mode based on the driving mode information, continue to determine whether the ON relay is closed.

[0075] The ON relay being closed indicates that the vehicle is powered on.

[0076] S405. When it is determined that the ON relay is closed, the vehicle is controlled to remain powered on or powered off according to the second external command.

[0077] Specifically, when the driving mode is determined to be manual driving mode based on the driving mode information, the vehicle cannot be powered on or off according to the third control command. Furthermore, the body controller can obtain the current state of the ON relay and determine whether it is closed. If the ON relay is closed, the vehicle is considered to be powered on. At this point, as long as a second external command is received that changes the state of the ON relay, if the second external command is a power-on command, the ON relay remains closed, meaning the vehicle remains powered on. If the second external command is a power-off command, the body controller can control the ON relay to open upon receiving the command, thereby powering off the vehicle. This ensures that the power-on / off control schemes in manual and automatic driving modes are decoupled and independent, guaranteeing the reliability and safety of vehicle power-on / off.

[0078] Optional, continue to refer to Figure 4 As shown, the control method further includes the following steps:

[0079] S406. If it is determined that the ON relay is not closed, continue to determine whether the vehicle is stationary.

[0080] S407. If the vehicle is stationary, the vehicle is powered off according to a third external command.

[0081] S408. If the vehicle is in motion, control the vehicle to power on according to the second external command.

[0082] Specifically, if the ON relay is not closed (i.e., it is in an open state), and the vehicle is already determined to be in manual driving mode, this could be because the driver switched from automatic driving mode to manual driving mode while the vehicle was in motion, or it could be because the vehicle has been in manual driving mode without any power-on operation. In this case, the actual power-on status of the vehicle can be further determined by checking whether the vehicle is stationary. If the vehicle is stationary, the body controller will directly receive a third external command and control the vehicle to shut down according to the third external command. Conversely, if the vehicle is not stationary, to ensure safe driving, the vehicle needs to be kept powered on. That is, the body controller will directly receive a second external command and control the vehicle to power on according to the second external command, causing the ON relay to close. This ensures that the vehicle can maintain a powered state in the event of an emergency, allowing for timely handling and thus ensuring the reliability and safety of the vehicle.

[0083] Optional, Figure 5A flowchart of the fifth vehicle power-on / off control method provided in the embodiments of the present invention is shown below. Figure 5 As shown, before acquiring driving mode information, the method further includes: determining whether the vehicle is malfunctioning; if the vehicle is malfunctioning, acquiring a second external command and controlling the vehicle to power on according to the second external command; if the vehicle is not malfunctioning, continuing to acquire driving mode information. Therefore, this control method includes the following steps:

[0084] S501. Obtain the first external command and determine whether the vehicle has triggered autonomous driving based on the first external command.

[0085] S502. After determining that the vehicle has not triggered autonomous driving and the first preset condition is met, a second external command is obtained, and the vehicle is powered on or off according to the second external command.

[0086] S503. After determining that the vehicle has triggered autonomous driving, determine whether the vehicle is malfunctioning.

[0087] S504. If the vehicle malfunctions, a second external command is obtained, and the vehicle is powered on according to the second external command.

[0088] S505: Obtain driving mode information and determine the current driving mode of the vehicle based on the driving mode information.

[0089] S506. Based on the driving mode information, determine that the current driving mode of the vehicle is automatic driving mode, obtain a third external command, and control the vehicle to power on or off according to the third external command.

[0090] Specifically, once the vehicle triggers autonomous driving, it is permitted to operate autonomously. Further assessment is needed to determine if a malfunction exists, ensuring the reliability and safety of subsequent autonomous driving. Optionally, vehicle malfunctions include autonomous driving mode failure. Understandably, an autonomous driving mode failure will prevent the vehicle from operating autonomously. There are many reasons for this failure, such as bus off, brake malfunction, or others; specific limitations are not listed here, and settings can be configured according to actual needs. In this case, the body controller can obtain a second external command to power on the vehicle for fault handling, ensuring vehicle safety. Conversely, if the vehicle is not faulty, the next step can be performed: continuing to acquire the vehicle's driving mode information and determining the current driving mode based on this information to ensure vehicle safety.

[0091] Optional, Figure 6 A flowchart of the sixth vehicle power-on / off control method provided in the embodiments of the present invention is shown below. Figure 6As shown, based on any of the above embodiments, before obtaining the first external command, the process includes: determining whether the vehicle is in an emergency stop state; if the vehicle is in an emergency stop state, obtaining a second external command and controlling the vehicle to power on according to the second external command; if the vehicle is not in an emergency stop state, continuing to obtain the first external command. For example, using... Figure 1 Based on the flowchart shown, the control method may further include the following steps:

[0092] S601. Determine if the vehicle is in an emergency stop state;

[0093] S602. If the vehicle is in an emergency stop state, obtain a second external command and control the vehicle to power on according to the second external command;

[0094] S603. If the vehicle is not in an emergency stop state, obtain the first external command and determine whether the vehicle has triggered autonomous driving based on the first external command.

[0095] S604. After determining that the vehicle has not triggered autonomous driving and the first preset condition is met, a second external command is obtained, and the vehicle is powered on or off according to the second external command.

[0096] S605. After determining that the vehicle has triggered autonomous driving and met the second preset conditions, obtain a third external command and control the vehicle to power on or off according to the third external command.

[0097] Specifically, before controlling the vehicle to power on or off, the body controller needs to determine if the vehicle is in an emergency stop state. Understandably, a serious malfunction typically triggers an emergency stop to ensure vehicle safety. Once in an emergency stop state, the body controller can no longer control the vehicle for driving or other operations. In this case, the body controller needs to obtain a second external command from the vehicle to control the vehicle to power on, ensuring the vehicle remains powered on and can handle the corresponding malfunction in an emergency, thus guaranteeing vehicle safety. Conversely, when the vehicle is not in an emergency stop state, it can continue to obtain the first external command to execute subsequent operations, further ensuring the safety and reliability of powering on or off the vehicle.

[0098] Based on the same inventive concept, embodiments of the present invention also provide an intelligent driving vehicle. Figure 7 This is a structural schematic diagram of an intelligent driving vehicle provided in an embodiment of the present invention, such as... Figure 7 As shown, the intelligent driving vehicle 100 includes a drive-by-wire chassis device 10, which is used to control the driving of the intelligent driving vehicle 100. The drive-by-wire chassis device 10 includes a body controller 11, which is used to execute the vehicle power-on / off control method in any of the above embodiments to complete the power-on or power-off operation of the intelligent driving vehicle 100.

[0099] Understandably, a drive-by-wire chassis typically includes five basic modules: drive-by-wire, steering-by-wire, brake-by-wire, parking-by-wire, and a body controller. These modules usually communicate via a CAN bus, which offers relatively high transmission speeds. Figure 7 The drive-by-wire chassis device 10 in the intelligent driving vehicle 100 is shown as an example only, and does not represent all examples. The body controller 11 can realize on-board power control (e.g., controlling the power-on or power-off operation of the intelligent driving vehicle), gateway, headlight control system, and windshield wiper control system, etc. In addition, the body controller is electrically connected to the vehicle controller (not shown) of the intelligent driving vehicle to realize data interaction and realize safe driving of the vehicle.
