Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric control lock vehicle, and particularly relates to an engine, a lock vehicle method, a vehicle controller and a vehicle. BACKGROUND

[0002] In the current lock vehicle mode through remote terminal and vehicle controller binding, after the remote terminal receives the binding activation lock vehicle instruction of the remote platform, the remote terminal binds with the vehicle controller. When the vehicle is powered on, the vehicle controller sends a request to the remote terminal through the CAN line. The remote terminal calculates and processes the request, and then sends the processing result to the vehicle controller through the CAN line. After the vehicle controller receives the processing result, it compares the result with the result calculated by itself. If the comparison is consistent, the handshake verification is successful. If the comparison is inconsistent, the handshake verification fails. However, for some customers who buy vehicles, when they need to make installment payments, some customers replace the vehicle controller themselves in order to avoid payment. The replaced vehicle controller cannot be controlled by the remote platform, that is, the customer cannot be prompted to complete the payment through the form of controlling the vehicle to lock the vehicle.

[0046] In view of the problem in the related art that some customers who buy cars by loaning money need to avoid payment when they need to make installment payments, some customers replace the vehicle controller by themselves, and the replaced vehicle controller cannot be controlled by the remote platform, that is, the customer cannot be prompted to complete the repayment by controlling the vehicle to lock it. The present application provides an engine, a locking method, a vehicle controller and a vehicle. Replacing the engine flywheel or the vehicle controller or the remote terminal alone will lock the vehicle, making the locking more reliable.

[0047] Other features and advantages of the present application will be set forth in the following description, and some will become apparent from the description, or will be learned by practice of the present application. The objects and other advantages of the present application can be achieved and obtained by the structures specifically pointed out in the written description, claims, and drawings.

[0048] The engine, locking method, vehicle controller and vehicle in the embodiments of the present application will be described in detail below in conjunction with the drawings.

[0049] Referring to Figure 1 , a schematic diagram of an engine according to an embodiment of the present application.

[0050] The engine includes an engine flywheel 1, a flywheel mounting shell 2 and an engine body; the first through hole 3 and the second through hole 4 are arranged on the circumference of the gear ring at a predetermined distance apart; the flywheel protection shell 2 is provided with a signal sensor 5, the signal sensor 5 is used to monitor the first through hole and the second through hole during the idle rotation of the engine flywheel, and send the monitoring signal of the first through hole or the second through hole to the vehicle controller 6, so that the vehicle controller judges whether to start the locking operation according to the received monitoring signal.

[0051] Specifically, Figure 1 The specific positions of the first through hole and the second through hole on the engine flywheel are not limited in the application. Through the above connection relationship, the signal sensor realizes signal interaction with the vehicle controller by monitoring the signals of the two through holes in real time, so that the vehicle controller can obtain the relevant information of the vehicle bound thereto in real time.

[0052] Referring to Figure 2 , a lock vehicle method flowchart provided by an embodiment of the application is shown, which is applied to the above engine and includes the following steps.

[0053] Step 201: When the engine is in an idle state, the vehicle controller receives the monitoring signal sent by the signal sensor.

[0054] Specifically, when the engine is in an idle state, the engine flywheel is in a uniform rotation state, at which time the signal sensor monitors the signals of the two through holes and sends the monitoring signal to the vehicle controller.

[0055] Step 202: The vehicle controller determines a first time when the monitoring signal is received for the first time, a second time when the monitoring signal is received for the second time, and a third time when the monitoring signal is received for the third time.

[0056] Specifically, since there are two through holes, a first through hole and a second through hole, on the flywheel, the monitoring signal is received for the first time when the flywheel monitors the through hole passing for the first time. The through hole may be the first through hole or the second through hole. The monitoring signal is received for the second time when the flywheel monitors the through hole passing for the second time. If the first monitored through hole is the first through hole, the second monitored through hole is the second through hole, and when the signal sensor monitors the through hole for the third time, it is the same through hole as the first monitored through hole. For example, the first monitored through hole is the first through hole at the first time; the second monitored through hole is the second through hole at the second time, and the third monitored through hole is the first through hole at the third time. However, when the first monitored through hole is the second through hole at the first time, the second monitored through hole is the first through hole at the second time, and the third monitored through hole is the second through hole at the third time.

[0057] Step 203: The vehicle controller determines whether to start the lock vehicle operation according to the first time, the second time, the third time, and the initial angle.

[0058] Specifically, the preset angle is an initial angle of an included angle between a first target line and a second target line, which is measured in advance when the engine is tested during factory trial, the first target line is a line connecting the center of the first through hole and the center of the flywheel of the engine, and the second target line is a line connecting the center of the second through hole and the center of the flywheel of the engine. The initial angle is stored in the vehicle controller of the tested vehicle.

[0059] When the customer purchases the vehicle, the vehicle controller can obtain the first time, the second time and the third time through the signal interaction with the signal sensor in step 202 once the vehicle is in an idle state.

[0060] The target angle formed between the first target line and the second target line in real time is calculated according to the first time, the second time and the third time in the following manner.

[0061] The vehicle controller calculates the time difference between the first time and the second time, determines a target ratio of the time difference to a period, wherein the period is the difference between the third time and the first time, determines the target angle based on the product of the target ratio and 360 degrees, and judges whether to start the lock operation based on the target angle and the initial angle stored in the vehicle controller in advance.

[0062] Specifically, for example, the first time is the time when the first through hole is monitored, the second time is the time when the second through hole is monitored, and the third time is the time when the third through hole is monitored. The target angle is obtained by multiplying the target ratio by 360 degrees, that is, the ratio of the time difference between the first through hole and the second through hole passing through the signal sensor to the period of one revolution of the first through hole is converted into the angle ratio of the target angle between the first target line and the second target line to 360 degrees. As an optional embodiment, in order to make the measured target angle more accurate, the signal sensor monitors a plurality of first times, second times and third times to obtain a plurality of calculated angles, and the vehicle controller finally obtains the target angle by averaging the plurality of calculated angles.

[0063] As an optional implementation, the target angle is compared with an initial angle pre-stored in the vehicle controller to determine whether to start the locking operation. Specifically, after the target angle is determined, the target angle is compared with the initial angle. When the target angle is different from the initial angle, it is determined that the angle between the first target line and the second target line monitored in real time is different from the initial angle pre-stored, that is, the vehicle controller is possibly replaced by the customer, and then the locking operation is started. It should be noted that the vehicle controller includes the vehicle controller when it is shipped or the vehicle controller replaced by the customer, and the vehicle controller is pre-compiled with the steps of the application.

[0064] As an optional implementation, the target angle is compared with an initial angle pre-stored in the vehicle controller to determine whether to start the locking operation. Specifically, after the target angle is determined, the target angle is compared with the initial angle. When the target angle is different from the initial angle, it is determined that the angle between the first target line and the second target line monitored in real time is different from the initial angle pre-stored, that is, the vehicle controller is possibly replaced by the customer, and then the locking operation is started. It should be noted that the vehicle controller includes the vehicle controller when it is shipped or the vehicle controller replaced by the customer, and the vehicle controller is pre-compiled with the steps of the application.

[0065] Specifically, in order to exclude the real-time error caused by the engine operation or other reasons, a preset threshold is set in the application. When the difference between the target angle and the initial angle is greater than the preset threshold, it is further determined that the vehicle controller with the other initial angle is replaced by the customer, and the locking operation is started.

[0066] As an optional implementation, the initial angle includes a first initial angle and a second initial angle, and the sum of the first initial angle and the second initial angle is 360 degrees.

[0067] Specifically, the target angle measured by the signal sensor is different due to different positions of the signal sensor. For example, referring to Figure 3 When the first through hole and the second through hole are arranged as shown in Figure 3 When the signal sensor is arranged at a position far from the first through hole and to the right of the second through hole, when the flywheel rotates clockwise, the signal sensor first monitors the second through hole at the first time, second monitors the first through hole at the second time, and third monitors the second through hole at the third time. At this time, the product of the target ratio and 360 is an acute angle. However, referring to Figure 4The signal sensor is arranged between the first through hole and the second through hole. When the flywheel rotates clockwise, the first through hole is monitored by the signal sensor for the first time, the first time point is the first time, the second through hole is monitored by the signal sensor for the second time, the second time point is the second time, and the first through hole is monitored by the signal sensor for the third time, the third time point is the third time. At this time, the product of the target ratio and 360 is an obtuse angle. The initial angle includes two angles, and the sum of the first angle and the second angle is 360 degrees. The two initial angles are arranged to avoid that the friction between the components slightly displaces the signal sensor during the operation of the flywheel, or the flywheel is reversed due to other conditions during the rotation. It should be noted that although the signal sensor is not fixedly arranged in the application, it must be ensured that the signal sensor can receive the signals sent by the first through hole and the second through hole.

[0068] As an optional implementation, based on the target angle and the initial angle pre-stored in the vehicle controller, it is determined whether to start the lock operation, comprising:

[0069] The vehicle controller determines a first difference value between the target angle and the first initial angle, and a second difference value between the target angle and the second initial angle;

[0070] For the first difference value, if the first difference value is greater than a first preset threshold or a second preset threshold, or if the second difference value is greater than the first preset threshold or the second preset threshold, the vehicle controller determines to start the lock operation;

[0071] The first preset threshold is pre-stored in the vehicle controller, and is used to represent the deviation value of the target angle and the first initial angle.

[0072] The second preset threshold is pre-stored in the vehicle controller, and is used to represent the deviation value of the target angle and the second initial angle.

[0073] Specifically, for the above two initial angles: the first initial angle and the second initial angle, the first preset threshold is pre-set for the first initial angle, and the second preset threshold is pre-set for the second initial angle. When the vehicle controller calculates the target angle, the difference value between the target angle and any initial angle is compared with the first preset threshold and the second preset threshold respectively. Finally, it is determined whether to start the lock operation.

[0074] The application provides a more complex anti-disassembly lock vehicle method, two through holes, a first through hole and a second through hole, are randomly punched on an engine flywheel when the engine is assembled at a factory, and an initial angle value between the first through hole and the second through hole is measured and calculated by a signal sensor when an idle speed is stable during engine trial running. Specifically, a signal convexity of the first through hole and the second through hole is detected when the flywheel rotates one circle, and the time difference between the first time and the second time and the time difference between the third time and the first time can be detected when the flywheel rotates one circle, and the initial angle is calculated according to the two time differences; after a remote terminal is bound to a vehicle controller, the vehicle controller ECU is powered on, the remote terminal and the ECU perform MD5 lock handshake verification through a CAN line, and the ECU performs lock vehicle operation with limited torque and speed after the verification fails; then, vehicle controller self-checking is performed, the target angle of the flywheel is detected after the vehicle controller receives a remote binding instruction, and then the target angle is compared with the initial angle stored when the vehicle controller is shipped from the factory, the comparison value is considered consistent within a preset threshold range, the remote terminal can bind the vehicle controller when the comparison value is consistent, and the binding fails when the comparison value is inconsistent. After the remote terminal binds the vehicle controller, the vehicle controller is provided with the above determination logic, and the engine flywheel, the vehicle controller or the remote terminal is replaced alone, and the lock vehicle operation is performed, so that the lock vehicle operation is more reliable.

[0075] Reference Figure 5 A detailed lock vehicle method is provided in the application.

[0076] Step 501: When the engine is in an idle state, the vehicle controller receives a monitoring signal sent by a signal sensor.

[0077] Step 502: The vehicle controller determines a first time when the monitoring signal is received for the first time, a second time when the monitoring signal is received for the second time, and a third time when the monitoring signal is received for the third time.

[0078] Step 503: The vehicle controller calculates the time difference between the first time and the second time.

[0079] Step 504: The vehicle controller determines a target ratio of the time difference to a circle length.

[0080] Step 505: The vehicle controller determines a target angle based on the product of the target ratio and 360 degrees of a circle.

[0081] Step 506: The vehicle controller determines a first difference between the target angle and a first initial angle, and a second difference between the target angle and a second initial angle.

[0082] Step 507: For the first difference, if the first difference is greater than a first preset threshold or a second preset threshold, or if the second difference is greater than the first preset threshold or the second preset threshold, the vehicle controller determines to start the lock vehicle operation.
