Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and more specifically, to a vehicle control method, system, device, engineering machinery, and electronic equipment. Background Technology

[0002] An alcohol interlock, also known as an alcohol-sensitive ignition interlock device, is a device installed in a car's ignition system to prevent the driver from starting the car if the alcohol concentration exceeds the safe standard.

[0003] Currently, the application of alcohol locks on engineering vehicles generally involves a hard-wired signal controlling the vehicle's start-up, meaning the vehicle cannot be started until it passes an alcohol test.

[0004] However, because the alcohol lock has a long preheating time, the vehicle waits too long each time it is powered on again. This can lead to the vehicle failing to start in an emergency, posing a safety hazard. Summary of the Invention

[0005] In view of this, the embodiments of this application aim to provide a vehicle control method, system, device, engineering machinery and electronic equipment to solve the problem that the vehicle cannot start before passing the alcohol test, which leads to a safety hazard when the vehicle needs to be moved urgently.

[0006] In a first aspect, the present invention provides a vehicle control method, comprising: Obtain the power-on signal; In response to the power-on signal, the start-up intention signal and the alcohol test result sent by the vehicle's alcohol lock device are acquired respectively; If the start intention signal is received but the alcohol test result is not received, the vehicle is controlled to enter the restricted start mode; The restricted start mode includes limiting the vehicle's speed to no more than a preset speed limit.

[0007] In one possible implementation, the restricted start-up mode further includes: restricting the operation of the vehicle.

[0008] In one possible implementation, the vehicle control method further includes: After receiving the alcohol test result sent by the alcohol lock device, if the alcohol test result is passed, the vehicle is controlled to enter the normal start mode after it is determined that the vehicle has stopped driving.

[0009] In one possible implementation, the vehicle control method further includes: If the alcohol test result is negative, the vehicle is controlled to remain in the restricted start mode.

[0010] In one possible implementation, controlling the vehicle to enter a restricted start mode when the start intention signal is received but the alcohol test result is not received includes: Enter self-test mode; If the self-test passes and the start intention signal is obtained, but the alcohol test result is not obtained, the vehicle is controlled to enter the restricted start mode.

[0011] In a second aspect, the present invention provides a vehicle control system, comprising: The first signal acquisition unit is used to acquire the power-on signal; The second signal acquisition unit is used to acquire the start intention signal and the alcohol test result sent by the vehicle's alcohol lock device in response to the power-on signal. The start control unit is used to control the vehicle to enter a restricted start mode when the start intention signal is received but the alcohol test result is not received. The restricted start mode includes limiting the vehicle's speed to no more than a preset speed limit.

[0012] Thirdly, the present invention provides a vehicle control device, comprising: a vehicle controller and an alcohol lock device; The vehicle controller includes the vehicle control system provided in the second aspect of the present invention; The alcohol lock device is used to collect alcohol data inside the vehicle and send the alcohol test results determined based on the alcohol data to the vehicle controller.

[0013] In one possible implementation, the vehicle control device further includes: a communication module; The alcohol lock device sends the alcohol test results to the vehicle controller via the communication module.

[0014] Fourthly, the present invention provides an engineering machinery, comprising: an engineering machinery body and a vehicle control system provided in the second aspect of the present invention.

[0015] Fifthly, the present invention provides an electronic device, the electronic device comprising: processor; Memory used to store the processor's executable instructions; The processor is used to execute the method provided in the first aspect of the present invention.

[0016] The vehicle control method provided by this invention acquires the vehicle's power-on signal, and then, in response to the power-on signal, acquires both the vehicle's start-up intention signal and the alcohol test result sent by the alcohol lock device. When the start-up intention signal is acquired but the alcohol test result is not, the method controls the vehicle to enter a restricted start-up mode that limits the vehicle's speed to a preset speed limit. This allows the vehicle to start before the alcohol test result is obtained, thus responding to emergencies. Simultaneously, by controlling the vehicle to only travel at the speed limit before the alcohol test result is obtained, driving risks are reduced. Therefore, while ensuring vehicle safety, this method solves the problem of the vehicle being unable to start in an emergency due to the long preheating time of the alcohol lock, posing a safety hazard.

[0024] Unless otherwise defined, the technical or scientific terms used in the embodiments of this specification shall have the ordinary meaning understood by one of ordinary skill in the art to which this specification pertains. The terms "first," "second," and similar terms used in the embodiments of this specification do not indicate any order, quantity, or importance, but are merely used to avoid confusion of constituent elements.

[0025] Unless the context otherwise requires, throughout this specification, "a plurality of" means "at least two," and "including" is interpreted as open-ended or encompassing, that is, "including, but not limited to." In the description of this specification, terms such as "one embodiment," "some embodiments," "exemplary embodiment," "example," "specific example," or "some examples" are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this specification. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example.

[0026] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this specification.

[0027] Understandably, for construction machinery equipped with alcohol interlock devices, the current standard is to control the vehicle's start via a hard-wired signal controlled by the alcohol interlock. This means the vehicle can only start after a passing alcohol test. This process requires the vehicle to be powered on, the alcohol interlock to preheat, and alcohol data to be collected. The alcohol test result is then derived from this data, and the vehicle can only be started if the test is passed. Therefore, in emergency situations such as needing to move the vehicle, this method cannot start the vehicle quickly, posing a safety hazard.

[0028] The present invention aims to solve the above problems. By directly controlling the vehicle to enter the limited start mode that restricts driving speed after the vehicle is powered on normally and the start intention signal is obtained, the vehicle can start and drive before the alcohol test results are obtained, which effectively avoids the problem of excessive vehicle start time and facilitates the response to emergency situations.

[0029] The present invention provides a vehicle control method executed on an electronic device, which may be a vehicle control unit (VCU), a smart terminal device such as a laptop, mobile phone, or tablet connected to the VCU, or a server remotely connected to the VCU.

[0030] See Figure 1 , Figure 1 This is a flowchart of a vehicle control method provided in an embodiment of the present invention, such as... Figure 1 As shown, the process of a vehicle control method provided in this embodiment of the invention mainly includes the following steps: S100, Obtain the power-on signal.

[0031] Specifically, the power-on signal is usually a low-voltage hard-wired signal, generated when the key is in the ON position, or when the one-button start function of a vehicle with keyless entry is triggered.

[0032] In some possible embodiments, when the key is in the ON position or the one-button start function is triggered, the VCU is woken up by the power-on signal and controls the power module to supply power to low-voltage components such as the battery management system (BMS) and motor controller (MCU), thereby completing the low-voltage power-on wake-up.

[0033] S110, in response to the power-on signal, acquire the start-up intention signal and the alcohol test result sent by the vehicle's alcohol lock device.

[0034] Understandably, after the low-voltage power-on is completed, the vehicle still needs a high-voltage power-on before it can start and drive normally. Specifically, the start intention signal is a high-voltage power-on trigger signal, which in some possible embodiments is generated when the brake is applied and the vehicle is in P / N gear.

[0035] Currently, for vehicles equipped with an alcohol lock device, the vehicle can only be powered on and started normally when a start-intention signal is received and the alcohol test result is passed. Therefore, in response to the power-on signal, the alcohol test result sent by the alcohol lock device must be obtained simultaneously with the start-intention signal.

[0036] S120. When a start intention signal is received but no alcohol test result is received, the vehicle is controlled to enter the restricted start mode.

[0037] Among them, the restricted start mode includes: limiting the vehicle's speed to no more than a preset speed limit.

[0038] Understandably, after the vehicle is powered on at low voltage, the alcohol lock is activated and requires a relatively long preheating period before alcohol data is collected from inside the vehicle to determine the alcohol test results.

[0039] Specifically, by receiving a start-up intention signal, such as when the driver applies the brakes, the system controls the vehicle to enter a restricted start-up mode that limits the vehicle's speed to a preset speed limit. This allows the vehicle to start and travel within the speed limit, avoiding the long start-up time required due to the time needed to obtain alcohol test results. This solves the safety hazard posed by the vehicle's inability to start in emergency situations where it needs to be moved.

[0040] It should be noted that the preset speed limit is a speed limit set based on driving safety considerations. Its specific value can be determined through experiments, experience, etc., for example, set to 20km / h, 15km / h, etc., and is not specifically limited here.

[0041] Understandably, it's impossible to determine whether a driver is driving under the influence of alcohol before obtaining the breathalyzer test results. For construction machinery and other work vehicles, such as excavators, operations are primarily performed by the driver operating the workpiece. Construction machinery is typically large, and the workpiece covers a wide area during operation. Therefore, the risk of operating such machinery while in an impaired state is extremely high.

[0042] Based on this, in a preferred embodiment, the restricted start-up mode further includes: restricting vehicle operation.

[0043] Specifically, by including restrictions on vehicle operation in the restricted start mode, the safety of starting the vehicle before obtaining alcohol test results is further improved.

[0044] In a preferred embodiment, the vehicle control method further includes: After receiving the alcohol test result from the alcohol lock device, if the alcohol test result is passed, the vehicle will be controlled to enter the normal start mode after the vehicle has been stopped.

[0045] Specifically, the restricted start mode limits the vehicle's speed to a preset speed limit and prohibits operation; while the normal start mode removes both speed and operation restrictions. Therefore, the same driver operation of the accelerator pedal can result in significant differences in vehicle speed. For example, assuming a preset speed limit of 20 km / h, in restricted start mode, a 50% accelerator pedal opening might correspond to a speed of 10 km / h, while in normal start mode, the same 50% accelerator pedal opening might correspond to a speed of 40 km / h. If, after receiving a passing alcohol test result from the alcohol lock device, the vehicle is immediately switched from restricted start mode to normal start mode, the sudden change in speed could easily lead to a dangerous situation.

[0046] Therefore, in this embodiment, when driving in the restricted start mode and receiving a passing alcohol test result from the alcohol lock device, the vehicle is switched to the normal start mode only after the vehicle stops (i.e., the driver operates the brake pedal to reduce the vehicle speed to zero). This removes the speed limit (not exceeding the preset speed limit) before the vehicle restarts, allowing normal driving and operation. This ensures that the driver can operate the vehicle normally after confirming there is no risk of drunk driving. Furthermore, it effectively guarantees the safety of mode switching, avoiding the sudden speed changes that can occur when switching directly from the restricted start mode to the normal start mode, thus improving vehicle control safety.

[0047] In a preferred embodiment, the vehicle control method further includes: If the alcohol test result is negative, the vehicle will be kept in restricted start mode.

[0048] In this embodiment, by keeping the vehicle at the speed limit when the alcohol test result is negative, the potential trouble caused by the vehicle failing to start is avoided, and driving safety is improved.

[0049] In a preferred embodiment, when a start-intention signal is received but no alcohol test result is received, controlling the vehicle to enter a restricted-start mode includes: Enter self-test mode; If the self-test passes and the start intention signal is received, but the alcohol test result is not obtained, the vehicle is controlled to enter the restricted start mode.

[0050] In this embodiment, by controlling the low voltage power supply to the vehicle and entering a self-test mode, such as detecting the status of the high voltage battery pack and the high voltage interlock circuit, the safety of high voltage power supply is ensured.

[0051] See Figure 2 This is a flowchart illustrating an example of vehicle start-up control using the vehicle control method provided in the above embodiments of the present invention, taking the VCU as an example. Figure 2 As shown, after receiving the power-on signal, the vehicle's VCU first performs a power-on self-test. After passing the self-test, it applies the brakes to the "Ready" position, limiting the vehicle speed to 20 km / h and restricting vehicle operation. Simultaneously, the vehicle's alcohol lock side preheats to prepare for alcohol data collection. After preheating, it collects alcohol data to obtain the alcohol test result, which is then sent to the VCU. Upon receiving the alcohol test result, the VCU determines whether the test is passed. If it fails, it continues to acquire the alcohol test result while maintaining the speed and operation restrictions. If it passes, it acquires the vehicle's speed, and when the speed reaches 0, it releases the speed and operation restrictions, allowing the vehicle to officially power on and enter normal driving mode.

[0052] As can be seen, the vehicle control method provided by the above embodiments of the present invention effectively solves the problem that the vehicle cannot be started in emergency situations due to the excessively long preheating time of the alcohol lock, posing a safety hazard. Furthermore, by setting a preset speed limit and restricting vehicle operation, the safety of starting the vehicle before obtaining the alcohol test results is effectively ensured.
