Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A control method and apparatus of an EPB, a key of a vehicle, an electronic device, and a computer-readable storage medium according to an embodiment of the present invention are described below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a control method of an EPB according to an embodiment of the present invention.

As shown in fig. 1, the control method of the EPB according to the embodiment of the present invention includes the following steps:

S101, acquiring a first control signal aiming at the EPB.

The main execution body of the EPB control method according to the embodiment of the present invention is a Body Control Module (BCM).

S102, identifying the source of the first control signal, and if the source is the key of the vehicle, detecting whether the switch of the EPB has a fault.

Optionally, identifying the source of the first control signal may include obtaining an attribute parameter of the first control signal, and identifying the source of the first control signal according to the attribute parameter.

The attribute parameters may include identification information of a transmitting end of the signal, a signal type, a value type, and the like. For example, the identification information may include a name, a number, etc., the signal type may include an analog signal, a digital signal, etc., and the value type may include a binary value, a current, a voltage, etc., without being limited thereto.

And S103, if the switch of the EPB has a fault, sending an execution command to the ESP, and controlling the EPB to be powered on and executing the action matched with the first control signal by the ESP according to the execution command.

In an embodiment of the present invention, the EPB may be controlled by combining a switch of the EPB and a key of the vehicle.

When the switch signals of the switch of the EPB and the switch of the EPB are not in fault, the EPB can be controlled through the switch of the EPB at the moment, the key of the vehicle does not control the EPB, the switch of the EPB can directly send the switch signal to an Electronic Stability Program (ESP), and the ESP controls the power-on of the EPB according to the switch signal and executes the action matched with the switch signal.

When at least one of the switch signals of the switch of the EPB and the switch of the EPB has a fault, the ESP can detect a parking fault code, the EPB can be controlled by a key of the vehicle, the switch of the EPB does not work on the EPB, the key of the vehicle can send a first control signal aiming at the EPB to the BCM, the BCM can send an execution command to the ESP after identifying that the source of the first control signal is the key of the vehicle, and the ESP controls the power-on of the EPB and executes the action matched with the first control signal according to the execution command.

Therefore, when the source of the first control signal is identified as the key of the vehicle, the method needs to detect whether the switch of the EPB is in failure at the moment so as to further judge whether the EPB needs to be controlled by the key of the vehicle. If the switch of the EPB has a fault, which indicates that the EPB needs to be controlled by a key of the vehicle at the moment, an execution command can be sent to the ESP, and the ESP controls the EPB to be powered on according to the execution command and executes the action matched with the first control signal, so that the normal use of the EPB function is realized when the switch of the EPB has a fault.

In summary, according to the control method of the EPB of the embodiment of the present invention, when it is identified that the source of the first control signal is the key of the vehicle and the switch of the EPB has a fault, the execution instruction may be sent to the ESP, the ESP controls the EPB to be powered on and executes the action matched with the first control signal according to the execution instruction, and the EPB can be controlled by the key when the switch of the EPB has the fault, so as to implement normal use of the EPB function, improve reliability of the EPB function, and effectively avoid a safety risk that the vehicle cannot be parked due to the failure of the EPB function.

As another possible embodiment, if the switch of the EPB is not faulty, which indicates that the EPB does not need to be controlled by the key of the vehicle at this time, the execution command is not sent to the ESP. The method can avoid the misoperation of the ESP under the conditions that a user touches a key unintentionally and a child plays, and has high reliability.

Optionally, if the switch of the EPB has no fault, a reminding message may be sent to the user to remind the user to control the EPB through the switch of the EPB. For example, a text message "please operate the switch of the EPB" may be displayed on a display area of a dashboard of the vehicle.

On the basis of the above embodiment, the step S102 of detecting whether the switch of the EPB has a fault may include, as shown in fig. 2:

s201, acquiring a signal sent by a switch of the EPB. Wherein the signals comprise voltage and current signals of the switch of the EPB.

S202, recognizing that the signal is not in the preset range, and determining that the switch of the EPB has a fault.

It can be understood that if the signal sent by the switch of the EPB is within the preset range, it can be determined that there is no fault with the switch of the EPB; if the signal sent by the switch of the EPB is not in the preset range, the switch of the EPB can be determined to have a fault. The preset range can be calibrated according to actual conditions and can be preset in the storage space of the BCM.

For example, if the EPB is controlled to be clamped by the switch of the EPB, the current of the switch of the EPB is increased to a preset first range, and if the current signal identifying the switch of the EPB is not in the preset first range, it may be determined that the switch of the EPB has a fault. The preset first range can be calibrated according to actual conditions and can be preset in a storage space of the BCM.

Thus, the method can determine whether there is a failure in the switch of the EPB by identifying whether the signal transmitted by the switch of the EPB is within a preset range.

On the basis of the above embodiment, the step S103 of sending the execution instruction to the ESP may include identifying that the first control signal is a control signal indicating EPB clamping, and then generating and sending to the ESP an execution instruction indicating clamping of the actuator of the EPB, and may further include identifying that the first control signal is a control signal indicating EPB release, and then generating and sending to the ESP an execution instruction indicating release of the actuator of the EPB.

Thus, the method may generate an execution instruction for indicating clamping of the actuator of the EPB when the first control signal indicates EPB clamping, and generate an execution instruction for indicating release of the actuator of the EPB when the first control signal indicates EPB release.

A control method of the EPB according to another embodiment of the present invention is described below with reference to fig. 3.

As shown in fig. 3, the control method of the EPB according to the embodiment of the present invention includes the following steps:

s301, monitoring the first operation, and acquiring the operation position of the monitored first operation.

The main execution subject of the EPB control method according to the embodiment of the present invention is a key of the vehicle.

The first operation refers to an operation performed by a user on a key of the vehicle.

S302, if the operation position is a target operation area on a key of the vehicle, a first control signal aiming at the EPB is generated, wherein the target operation area is an operation area configured on the key aiming at the EPB.

It will be appreciated that the target operating region may be preset on the key.

Optionally, if the operation position is a target operation area on the key, the number of times of the first operation is 1, and the corresponding operation duration is less than or equal to a preset duration, the generated first control signal may be a control signal indicating EPB clamping; if the number of times of the first operation is 1 and the corresponding operation duration is greater than the preset duration, the generated first control signal may be a control signal indicating EPB release. The preset time length may be calibrated according to actual conditions, for example, may be calibrated to be 2 seconds.

S303, sending the first control signal to the BCM.

It is understood that, if the operation position is a target operation region on a key of the vehicle, indicating that the user has an operation intention for the EPB, the first control signal for the EPB may be generated and transmitted to the BCM.

It should be noted that details that are not disclosed in the EPB control method according to the embodiment of the present invention refer to details disclosed in the above embodiments of the present invention, and are not described herein again.
