Description

[0001] Embodiments of the present application relate to the technical field of vehicles, and in particular to a vehicle control method and device, a vehicle body controller, and a vehicle.

[0002] In the process of driving a vehicle, a sudden scenario may occur in which the vehicle needs to be powered off and the hazard warning light needs to be turned on. For a vehicle with a high-voltage system, the ignition button is canceled, and in the process of driving, the vehicle can only be powered off through an additional power-off button or a virtual switch on the vehicle display screen. In the above-mentioned sudden scenario, the user needs to press the power-off button or the virtual switch first to power off the vehicle, and then press the hazard warning light switch to turn on the hazard warning light. The above process has two problems: first, the operation is relatively cumbersome, which is not conducive to safe driving of the user in the above-mentioned sudden scenario; second, the additional power-off button increases the production cost, and when the virtual switch on the vehicle display screen is used to power off the vehicle, the vehicle cannot be reliably powered off if the vehicle display screen is dead.

[0003] Embodiments of the present application provide a vehicle control method and device, a vehicle body controller, and a vehicle. The hazard warning light switch is reused to simultaneously power off the vehicle and turn on the hazard warning light. On the one hand, the operation process is simplified and the safety is improved. On the other hand, no additional power-off button is needed, which reduces the production cost, and the vehicle display screen is not needed to rely on the virtual switch, thereby improving the reliability of the vehicle power-off.

[0004] In a first aspect, embodiments of the present application provide a vehicle control method, which includes:

[0005] When the vehicle is in an ON gear, a pressing operation on a hazard warning light switch is detected.

[0006] If the pressing time of the pressing operation is not less than a first set threshold or the pressing frequency of the pressing operation is not less than a second set threshold, the real-time vehicle speed is obtained.

[0007] If the real-time vehicle speed indicates that the vehicle is in a driving state, the low-voltage electrical equipment in the vehicle is powered off, and the hazard warning light is controlled to enter a working state.

[0008] ​​​In the embodiments of the present application, when the vehicle is in the ON gear driving state, if a sudden scene occurs that requires the vehicle to be powered off and the hazard warning light to be turned on, the user only needs to long press the hazard warning light switch or press the hazard warning light switch multiple times in a unit time, so as to simultaneously realize the vehicle power-off and the hazard warning light turning on. On the one hand, the method simplifies the operation process and improves the safety in the sudden scene; on the other hand, without adding an additional power-off button, the production cost is reduced, and at the same time, the method does not need to rely on the virtual switch in the car display screen, thereby improving the reliability of the vehicle power-off.

[0009] Optionally, if the real-time speed represents that the vehicle is in a stationary state, the low-voltage electrical equipment in the vehicle is controlled to be powered off.

[0010] In the embodiments of the present application, when the vehicle is in the ON gear stationary state, if a scene occurs that requires the vehicle to be powered off, the user only needs to long press the hazard warning light switch or press the hazard warning light switch multiple times in a unit time, so as to realize the vehicle power-off, without adding an additional power-off button, thereby reducing the production cost, and at the same time, the method does not need to rely on the virtual switch in the car display screen, thereby improving the reliability of the vehicle power-off.

[0011] Optionally, the control of the low-voltage electrical equipment in the vehicle to be powered off comprises:

[0012] The target relay is controlled to be in an open state, so as to make the low-voltage electrical equipment in the vehicle be powered off, wherein the target relay comprises an auxiliary power supply relay ACC, an ignition 1 power supply relay IGN1 and an ignition 2 power supply relay IGN2.

[0013] In the embodiments of the present application, the low-voltage electrical equipment can be powered off by respectively controlling the ACC, IGN1 and IGN2 to be in an open state.

[0014] Optionally, after detecting the pressing operation on the hazard warning light switch, the method further comprises:

[0015] If the pressing time of the pressing operation is less than the first set threshold, the hazard warning light is controlled to be in a working state.

[0016] In the embodiments of the present application, when the vehicle is in the ON gear, if a scene occurs that requires the vehicle to turn on the hazard warning light alone, the user only needs to short press the hazard warning light switch, so as to turn on the hazard warning light, that is, the original function of the hazard warning light switch is reserved through the specific pressing design.

[0017] Optionally, the method further comprises:

[0018] When the vehicle is in the OFF gear, it is detected whether the hazard warning light is in a working state;

[0019] If no, and a pressing operation for the hazard warning light switch is detected;

[0020] In response to the pressing operation, the hazard warning light is controlled to enter an active state.

[0021] In the embodiments of the present application, in the case that the vehicle is in the OFF gear and the hazard warning light is not active, a long pressing operation, a short pressing operation, or a plurality of pressing operations in a unit time (i.e., a medium-high frequency pressing operation) on the hazard warning light switch can all control the hazard warning light to enter the active state.

[0022] Optionally, after detecting whether the hazard warning light is in the active state, the method further includes:

[0023] If yes, and a pressing operation for the hazard warning light switch is detected;

[0024] In response to the pressing operation, the hazard warning light is controlled to exit the active state.

[0025] In the embodiments of the present application, in the case that the vehicle is in the OFF gear and the hazard warning light is active, a long pressing operation, a short pressing operation, or a plurality of pressing operations in a unit time (i.e., a medium-high frequency pressing operation) on the hazard warning light switch can all control the hazard warning light to exit the active state.

[0026] Optionally, the first set threshold is 5s, and the second set threshold is 1 time / s.

[0027] In the embodiments of the present application, the first set threshold is 5s, and the second set threshold is 1 time / s. By reasonably setting the thresholds, the vehicle can accurately identify different types of pressing operations of the user, so as to accurately perform the actions. At the same time, the pressing time is prevented from being too long or the pressing frequency from being too high, thereby ensuring the user experience.

Detailed Implementation Methods

[0061] To better understand the technical solutions in this specification, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0062] It should be noted that the described embodiments are merely a part of the embodiments of the present specification, rather than all the embodiments. Based on the embodiments in the present specification, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present specification.

[0063] The terms used in the embodiments of the present application are merely for the purpose of describing specific embodiments, and are not intended to limit the present specification. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0064] At present, in the process of driving a vehicle by a user, a sudden scene may occur in which the vehicle needs to be powered off and the hazard warning light needs to be turned on. For example, during the driving of a new energy vehicle on a highway, a battery self-ignition problem occurs. In order to avoid the further spread of the battery combustion and to remind surrounding vehicles to pay attention to safety, the vehicle needs to be powered off and the hazard warning light needs to be turned on.

[0065] For a vehicle with a high-voltage door opening, the ignition button is cancelled, and during driving, the vehicle can only be powered off through an additional power-off button or a virtual switch on the vehicle machine display screen. Then in the above-mentioned sudden scene, the user needs to press the power-off button or the virtual switch first to perform the power-off operation, and then press the hazard warning light switch to turn on the hazard warning light.

[0066] The above process has two problems: first, the operation is relatively cumbersome, which is not conducive to safe driving by the user in the above-mentioned sudden scene; second, the additional power-off button for powering off the vehicle increases production costs, and when the virtual switch on the vehicle machine display screen is used to power off the vehicle, reliable vehicle power-off cannot be achieved once the vehicle machine is dead.

[0067] In view of this, the embodiments of the present application provide a control method of a vehicle. In the method, when the vehicle is in an ON gear driving state, if a sudden scene occurs in which the vehicle needs to be powered off and the hazard warning light needs to be turned on, the user only needs to long press the hazard warning light switch or press the hazard warning light switch multiple times in a unit time, so as to simultaneously achieve the vehicle power-off and the hazard warning light turning on. The method, on the one hand, simplifies the operation process and improves the driving safety in the sudden scene; on the other hand, without the need to add an additional power-off button, the production cost is reduced, and at the same time, the vehicle does not need to rely on the virtual switch in the vehicle machine display screen, thereby improving the reliability of the vehicle power-off.

[0068] The technical solutions provided by the embodiments of the present application will be described below with reference to the drawings.

[0069] Please refer to Figure 1A flowchart of a control method of a vehicle is provided in the embodiments of the present application. The method can be applied to a body control module (BCM). The flow of the method is described as follows:

[0070] In step 101, a press operation on the hazard warning light switch is detected when the vehicle is in the ON gear.

[0071] In the embodiments of the present application, when the vehicle is in the ON gear, the vehicle has provided power support for all electronic devices in the vehicle. These electronic devices include, but are not limited to, a sound system, an air conditioning system, a navigation system, and a vehicle control unit, etc. At this time, it can be detected whether there is a relevant operation of the user, for example, whether there is a press operation on the hazard warning light switch, so that the relevant operation of the user can be responded to in a timely manner subsequently.

[0072] In step 102, the real-time vehicle speed is obtained if the press duration of the press operation is not less than a first set threshold or the press frequency of the press operation is not less than a second set threshold.

[0073] In the embodiments of the present application, after detecting the press operation of the user, the press operation type can be determined in combination with the press duration or the press frequency of the press operation.

[0074] For example, if the press duration of the press operation is not less than the first set threshold, it can be considered that the press operation on the hazard warning light switch by the user is a long press operation. Conversely, if the press duration of the press operation is less than the first set threshold, it can be considered that the press operation on the hazard warning light switch by the user is a short press operation. Here, the first set threshold can be 3s, 4s, or 5s, as long as the vehicle can accurately distinguish between the short press operation and the long press operation of the user, so as to accurately respond, while avoiding too long press time and ensuring user experience. The present application does not particularly limit the first set threshold.

[0075] For example, if the first set threshold is 5s, if the press duration of the press operation of the user is detected to be 6s, i.e., the press duration of the press operation of the user is greater than the first set threshold, it can be considered that the press operation of the current user is a long press operation. If the press duration of the press operation of the user is detected to be 2s, i.e., the press duration of the press operation of the user is less than the first set threshold, it can be considered that the press operation of the current user is a short press operation.

[0076] For example, if the pressing frequency of the pressing operation is not less than the second set threshold, the pressing operation of the user on the hazard warning light switch can be considered as a medium-high frequency pressing operation; otherwise, if the pressing frequency of the pressing operation is less than the second set threshold, the pressing operation of the user on the hazard warning light switch can be considered as a low frequency pressing operation. Here, the second set threshold can be 1 time / s, as long as the vehicle can accurately distinguish the short pressing operation of the user from the long pressing operation, so as to accurately respond, and at the same time, avoid too long pressing time, so as to ensure the user experience. The first set threshold is not particularly limited in the present application.

[0077] For example, if the second set threshold is 1 time / s, if it is detected that the pressing operation of the user is pressed 3 times within 2 seconds, i.e., the pressing frequency is 1.5 times / s, at this time, it is determined that the pressing frequency of the pressing operation of the user is greater than the second set threshold, and the pressing operation of the current user can be considered as a medium-high frequency pressing operation. If it is detected that the pressing operation of the user is pressed 1 time within 2 seconds, i.e., the pressing frequency is 0.5 times / s, at this time, it is determined that the pressing frequency of the pressing operation of the user is less than the second set threshold, and the pressing operation of the current user can be considered as a low frequency pressing operation.

[0078] After determining the type of the pressing operation of the user, it is considered that the response demand of the user can be different in different vehicle running states. Therefore, how to respond to the pressing operation of the user can be determined in combination with the running state of the current vehicle.

[0079] For example, the real-time vehicle speed can be obtained, and it is determined whether the current vehicle is in a stationary state or a driving state according to the obtained real-time vehicle speed. Then, the pressing operation of the user is responded to according to the different running states of the vehicle.

[0080] Step 103: If the real-time vehicle speed represents that the vehicle is in a driving state, the low-voltage electrical equipment in the vehicle is powered off, and the hazard warning light is controlled to enter a working state.

[0081] In the embodiment of the present application, if it is determined that the pressing operation of the user on the hazard warning light switch is a long pressing operation or a medium-high frequency pressing operation, and the real-time vehicle speed represents that the vehicle is currently in a driving state, it can be considered that the current demand of the user is a first response demand, i.e., the vehicle needs to be powered off, and the hazard warning light needs to be turned on. At this time, the low-voltage electrical equipment in the vehicle can be controlled to be powered off, and the hazard warning light can be controlled to enter a working state.

[0082] For example, when the user drives the vehicle on a highway, at this time the vehicle is in the ON gear driving state, if the battery self-ignition problem occurs, in order to avoid the further spread of battery combustion, and at the same time to remind the surrounding vehicles to pay attention to safety, the vehicle needs to be powered off, and the hazard warning light is turned on. Then the user can control the vehicle to be powered off and the hazard warning light to be turned on at the same time by long pressing or high-frequency pressing the hazard warning light switch.

[0083] In some embodiments, it is considered that the user's desired demand may only be to power off the vehicle. Therefore, in the embodiments of the present application, the user's pressing operation type and the current running state of the vehicle can be combined to make a response of powering off the vehicle alone.

[0084] Please refer to Figure 2 A flowchart of a method for controlling the vehicle to be powered off only is provided in the embodiments of the present application. After step 102 is executed, step 104 can also be continued to be executed.

[0085] Step 104: If the real-time speed represents that the vehicle is in a stationary state, control the low-voltage electrical equipment in the vehicle to be powered off.

[0086] In the embodiments of the present application, when the vehicle is in the ON gear stationary state, if the user implements the long pressing operation or the high-frequency pressing operation on the hazard warning light switch, it can be considered that the user's current demand is the second response demand, that is, only the vehicle needs to be powered off, at this time the low-voltage electrical equipment in the vehicle can be controlled to be powered off.

[0087] For example, if the vehicle needs to be repaired, the user drives the vehicle to the repair shop, at this time the vehicle is in the ON gear stationary state, in order to facilitate the repair, the vehicle needs to be powered off. Then the user can control the low-voltage electrical equipment in the vehicle to be powered off alone by long pressing or high-frequency pressing the hazard warning light switch.

[0088] The method for controlling the low-voltage electrical equipment in the vehicle to be powered off is described below.

[0089] Please refer to Figure 3 A flowchart of a method for controlling the low-voltage electrical equipment in the vehicle to be powered off is provided in the embodiments of the present application. The control of the low-voltage electrical equipment in the vehicle to be powered off in step 103 or step 104 can be realized by executing sub-step 201:

[0090] Step 201: Control the target relay to be in an open state, so as to make the low-voltage electrical equipment in the vehicle to be powered off.

[0091] In the embodiments of the present application, the target relay can be controlled to switch from the closed state to the open state, so as to power off the low-voltage devices in the vehicle. For example, when the target relay is the auxiliary power supply relay ACC, if the ACC is in the open state, the devices such as the car machine system and the cigarette lighter will be powered off; when the target relay is the ignition 1 power supply relay IGN1, if the IGN1 is in the open state, all the controllers will be powered off; when the target relay is the ignition 2 power supply relay IGN2, if the IGN2 is in the open state, the devices such as the windscreen wiper will be powered off.

[0092] In some embodiments, it is considered that the demand that the user wants to be only to turn on the hazard warning light. Therefore, in the embodiments of the present application, the response of turning on the hazard warning light alone can be made in combination with the pressing operation type of the user.

[0093] Please refer to Figure 4 A flowchart of a method for controlling the turning on of the hazard warning light is provided in the embodiments of the present application. After step 101 is executed, step 105 can also be executed:

[0094] Step 105: If the pressing duration of the pressing operation is less than the first set threshold, the hazard warning light is controlled to enter the working state.

[0095] In the embodiments of the present application, when the vehicle is in the ON gear, if the pressing duration of the pressing operation performed by the user on the hazard warning light switch is less than the first set threshold, that is, the pressing operation performed by the user is a short pressing operation, at this time, whether the vehicle is in the stationary state or the driving state, the hazard warning light is controlled to enter the working state.

[0096] For example, when the user drives the vehicle on the highway at this time, the vehicle is in the ON gear driving state, if the vehicle prompts a fault, but the vehicle can still drive, at this time, the user needs to drive the vehicle to the repair shop. In order to remind the surrounding vehicles to pay attention to safety, the vehicle needs to turn on the hazard warning light. Then the user can control the vehicle to turn on the hazard warning light by short pressing the hazard warning light switch.

[0097] For another example, the user drives the vehicle to temporarily park on the roadside, and does not power off the vehicle by other means, at this time, the vehicle is in the ON gear stationary state, in order to remind the surrounding vehicles and pedestrians to pay attention to safety, the vehicle needs to turn on the hazard warning light. Then the user can control the vehicle to turn on the hazard warning light by short pressing the hazard warning light switch.

[0098] In some embodiments, it is considered that there is also a demand of turning on or off the hazard warning light when the vehicle is in the off gear (OFF gear). Therefore, how to turn on and off the hazard warning light when the vehicle is in the OFF gear is described below.

[0099] Please refer to Figure 5A flowchart of a method for turning on and off a hazard warning light when the vehicle is in OFF gear is provided in the embodiments of the present application. The flow of the method is described as follows:

[0100] Step 301: When the vehicle is in OFF gear, it is detected whether the hazard warning light is in the working state.

[0101] Step 302: If not, and the pressing operation on the hazard warning light switch is detected.

[0102] Step 303: In response to the pressing operation, the hazard warning light is controlled to enter the working state.

[0103] In the embodiments of the present application, when the vehicle is in OFF gear and the hazard warning light is not working, the hazard warning light can be controlled to enter the working state by implementing the long pressing operation, the short pressing operation, or the multiple pressing operations in a unit time on the hazard warning light switch.

[0104] For example, the user drives the vehicle to temporarily park on the roadside, and the vehicle is powered off by other means, at this time the vehicle is in OFF gear, in order to remind the surrounding vehicles and pedestrians to pay attention to safety, the vehicle needs to turn on the hazard warning light. Then the user can control the vehicle to turn on the hazard warning light by short pressing, long pressing or high-frequency pressing the hazard warning light switch.

[0105] Step 304: If it is detected that the hazard warning light is already in the working state, and the pressing operation on the hazard warning light switch is detected.

[0106] Step 305: In response to the pressing operation, the hazard warning light is controlled to exit the working state.

[0107] In the embodiments of the present application, when the vehicle is in OFF gear and the hazard warning light is already working, the hazard warning light can be controlled to exit the working state by implementing the long pressing operation, the short pressing operation, or the multiple pressing operations in a unit time (i.e. high-frequency pressing operation) on the hazard warning light switch.

[0108] For example, the user drives the vehicle to temporarily park on the roadside, and the vehicle is powered off by other means, at this time the vehicle is in OFF gear, and the hazard warning light has been turned on by pressing the hazard warning light switch. If the user temporarily stops the vehicle, the user needs to control the vehicle to drive again, and needs to turn off the hazard warning light of the vehicle. Then the user can control the vehicle to turn off the hazard warning light by short pressing, long pressing or high-frequency pressing the hazard warning light switch.
