Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of vehicle remote control, and particularly relates to a method for predicting in advance the failure of vehicle remote control, a vehicle control unit and a remote controller. Background Art
[0002] The existing logic for the loss of remote control signal of a skateboard chassis is that the remote control command is sent to the receiver through a wireless signal. The receiver converts the wireless signal into a CAN signal and then transmits it to the vehicle control unit (VCU). When the receiver fails to receive the remote control command, the receiver will send an identification signal indicating the loss of the remote control signal to the VCU. When the vehicle remote control signal is weak and the remote controller is disconnected, after continuously losing the signal for 2 seconds, the remote control receiver will report the loss of the remote control signal. If the VCU receives this signal within 1 second continuously, it will control the vehicle to perform an emergency brake to stop the vehicle. At this time, the vehicle control unit VCU will take emergency braking according to the identification bit of the remote control loss signal.
[0003] The existing method has the following disadvantages: it is very difficult to ensure the time consistency of the reported identification bit of the disconnection of the remote controller; there are great potential safety hazards in the delay after the disconnection of the remote controller when the vehicle speed is too high. When remotely controlling, as the distance between the vehicle and the operator becomes farther and farther, it is very difficult for the human eye to quickly and accurately judge whether the vehicle is about to exceed the remote control distance range, which is likely to cause the vehicle to get out of control due to the long distance; in addition, within the effective range of the remote control distance, it is impossible to effectively judge that the poor remote control signal caused by environmental interference leads to the vehicle getting out of control. There is a certain delay in the transmission of the operation instruction from the wireless signal to the CAN signal to the VCU, and at the same time, the signal fed back by the VCU to the remote controller will also be delayed. Therefore, it is often only after the vehicle has been out of control for a period of time that it can be known from the remote controller display. And the accumulation of this delay will increase the emergency braking reaction time after the vehicle gets out of control, which will cause very serious out-of-control accidents when the vehicle speed is too fast.
[0004] Therefore, a new solution is needed to monitor the remote control signal in real time, inform the operator in advance before the remote controller is about to be disconnected, and at the same time, the VCU takes effective braking in time to reduce the potential safety hazards caused by the loss of the remote control signal of the vehicle in the remote control mode.

[0026] To make the objectives, technical solutions, and advantages of the present disclosure more clear and understandable, the following further elaborates on the present disclosure in detail with reference to specific embodiments and the accompanying drawings.
[0027] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present invention should have the ordinary meanings understood by those of ordinary skill in the field to which the present disclosure pertains.

The terms such as "upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.
[0028] The embodiments of the present invention provide a vehicle remote control system. As shown in the Figure 1 accompanying drawings, the vehicle remote control system includes: a remote controller, a receiver, and a vehicle controller. The remote controller is wirelessly communicatively connected to the receiver and uses a frequency of 433Mhz for wireless communication. The receiver is connected to the vehicle controller via a CAN bus. The remote controller transmits a 433Mhz remote control signal and the remote controller received signal strength to the receiver. The receiver detects the heartbeat signal between the receiver and the remote controller, determines the remote control signal strength according to the received remote control signal, and converts the remote controller received signal strength, the remote control signal strength, and the heartbeat signal into CAN signals, and then transmits them to the vehicle controller via the CAN bus. The vehicle controller detects whether the remote controller received signal strength and the remote control signal strength meet a first preset condition; if it is detected that the remote controller received signal strength and the remote control signal strength meet the first preset condition, then the vehicle controller detects whether the heartbeat signal meets a second preset condition; if the heartbeat signal meets the second preset condition, then the vehicle controller controls the vehicle to decelerate and brake.
[0029] In an embodiment of the present invention, the receiver also feeds back the receiver feedback signal corresponding to the received remote control signal and the remote control signal strength to the remote controller. The remote controller determines the remote controller received signal strength according to the received receiver feedback signal, and the remote controller received signal strength is the signal strength of the receiver feedback signal. The remote controller performs remote control failure judgment according to the remote controller received signal strength and the remote control signal strength, and gives an alarm prompt according to the judgment result. If it is judged that the remote controller received signal strength or the remote control signal strength is less than the first threshold and greater than the second threshold, the buzzer set in the remote controller is controlled to give an alarm prompt at a preset frequency, where the first threshold is the signal strength warning threshold, the second threshold is the emergency braking threshold, and the second threshold is less than the first threshold. If it is judged that the remote controller received signal strength or the remote control signal strength is less than the second threshold, the buzzer is controlled to sound continuously.
[0030] The vehicle remote control system according to an embodiment of the present invention predicts the vehicle remote control failure in advance according to Figure 2 the process shown, including:
[0031] Step 100: Perform normal remote control.
[0032] The remote controller performs normal remote control on the vehicle.
[0033] Step 101: Determine whether one of the remote controller received signal strength and the remote control signal strength is less than the first threshold. If so, execute step 102; otherwise, return to step 100.
[0034] According to the obtained remote controller received signal strength and the remote control signal strength, determine whether one of them is less than the first threshold. If so, execute step 102; otherwise, it means that the remote controller is normal and normal remote control can be performed, and return to step 100. The first threshold is the warning threshold and can be set as needed. For example, it can be set as the signal strength value 15 s before out of control. The first threshold is preferably 110.
[0035] Step 102: Give an alarm prompt at a preset frequency.
[0036] If the remote controller received signal strength or the remote control signal strength is less than the first threshold, the buzzer set in the remote controller is controlled to emit an alarm sound at a preset frequency to give an alarm prompt. The preset frequency is preferably once per second.
[0037] Step 103: Determine whether both the remote controller received signal strength and the remote control signal strength are less than the second threshold. If so, execute step 104; otherwise, return to step 102.
[0038] Among them, the second threshold is the emergency braking threshold, preferably 95.
[0039] Step 104: The warning sound sounds continuously.
[0040] If both the remote control receiving signal strength and the remote control signal strength are less than the second threshold, it indicates that the remote control has failed, and the buzzer warning sound set in the remote control sounds continuously.
[0041] Step 105: Determine whether the heart rate is less than the third threshold. If so, execute Step 106; otherwise, return to Step 104.
[0042] Judge whether the heart rate is less than the third threshold according to the obtained heart rate signal. Among them, the value range of the heart rate is 0-1, and the third threshold is preferably 0.5.
[0043] Step 106: Control the vehicle to decelerate and brake.
[0044] If the heart rate is less than the third threshold, it indicates that the remote control has failed, and control the vehicle to decelerate and brake emergently. In this way, it is possible to predict in advance whether the remote control has failed, and then perform effective emergency braking in time, reducing the safety hazard caused by the loss of the remote control signal when the vehicle is in the remote control mode.
[0045] In the embodiment of the present invention, by proposing to digitalize the quality of the remote control signal strength data, the signal strength changes caused by the remote control distance and the spatial environment interference to the remote control can be obtained in real time. This signal strength value is inversely proportional to the remote control failure probability. The smaller the value, the higher the remote control failure probability. Then, through the method of test calibration, the signal strength warning threshold and the emergency braking threshold before failure of the actual vehicle are measured. On this basis, heart rate protection detection is added, and double-reliable judgment is used to guide the vehicle controller VCU to give a warning and emergency braking before the remote control fails, thus greatly reducing the driving distance after the vehicle gets out of control.
[0046] The embodiment of the present invention also provides a method for predicting in advance the failure of vehicle remote control. The method for predicting in advance the failure of vehicle remote control in the embodiment of the present invention is applied to the vehicle controller. As shown in the appendix Figure 3 The method for predicting in advance the failure of vehicle remote control includes:
[0047] Step S11: The vehicle controller acquires the remote control receiving signal strength, the remote control signal strength, and the heart rate signal in real time.
[0048] In an embodiment of the present invention, the receiver wirelessly receives the control signal of the remote controller and the remote controller received signal strength returned by the remote controller, and determines the remote control signal strength according to the remote control signal. Among them, the remote controller received signal strength mainly monitors the signal quality of the receiver feedback signal forwarded by the receiver received by the remote controller. When the signal quality is weak, it will cause a transmission delay or even interruption of the signal received by the remote controller from the vehicle controller. The remote control signal strength mainly monitors the signal quality of the signal transmitted from the remote controller received by the receiver. When the signal quality is weak, it will cause a transmission delay or even interruption of the remote controller command signal received by the VCU.
[0049] The receiver filters the original signals of the remote controller received signal strength and the remote control signal strength by means of mean filtering, so that the numerical fluctuations of the signals are stronger and the stability is stronger. The remote controller received signal strength and the remote control signal strength after filtering each occupy one byte in the CAN message, with a minimum value of 0 and a maximum value of 255. 0-255 represents the signal strength from weak to strong. The receiver also detects the heartbeat signal between the receiver and the remote controller. The heartbeat signal is used to monitor the normal signal fluctuations of the remote controller and the receiver sent to the VCU in real time. The signal period is 1s, and the value increases periodically from 0-15 cycles. When the signal fluctuations are chaotic, the period will change irregularly.
[0050] The vehicle controller receives the remote controller received signal strength, the remote control signal strength, and the heartbeat signal transmitted from the receiver in real time through the CAN method.
[0051] Step S12: The vehicle controller detects whether the remote controller received signal strength and the remote control signal strength meet a first preset condition.
[0052] In an embodiment of the present invention, the vehicle controller detects whether the remote controller received signal strength is less than a second threshold, and detects whether the remote control signal strength is less than the second threshold; if it is detected that both the remote controller received signal strength and the remote control signal strength are less than the second threshold, it is determined that the remote controller received signal strength and the remote control signal strength meet the first preset condition. The second threshold can be set as needed, preferably 95.
[0053] Step S13: If it is detected that the remote controller received signal strength and the remote control signal strength meet the first preset condition, the vehicle controller detects whether the heartbeat signal meets a second preset condition.
[0054] In an embodiment of the present invention, the vehicle controller determines whether the heartbeat frequency is less than a third threshold according to the heartbeat signal; if it is determined that the heartbeat frequency is less than the third threshold, it is determined that the heartbeat signal meets the second preset condition. The third threshold can be set as needed, and is preferably 0.5.
[0055] Step S14: If the heartbeat signal meets the second preset condition, the vehicle controller controls the vehicle to decelerate and brake.
[0056] In an embodiment of the present invention, if the remote control receiver signal strength and the remote control signal strength meet the first preset condition, and the heartbeat signal meets the second preset condition, that is, both the remote control receiver signal strength and the remote control signal strength are less than the second threshold, and whether the heartbeat frequency is less than the third threshold, it indicates that the remote control is far from the vehicle at this time, or the surrounding environment seriously interferes with the signal, and the remote control has failed. The vehicle controller controls the vehicle to decelerate and brake. Figure 4 It is a relationship diagram of signal strength and remote control distance. From Figure 4 it can be seen that as the distance between the vehicle remote control and the receiver increases, the signal strength fluctuates accordingly. When the distance exceeds the range, the signal strength is lower than the second threshold, and the remote control will be out of control, and emergency braking needs to be taken to prevent potential safety hazards.
[0057] The method for predicting in advance the failure of the vehicle remote control in the embodiment of the present invention includes the vehicle controller obtaining in real time the remote control receiver signal strength, the remote control signal strength, and the heartbeat signal; the vehicle controller detecting whether the remote control receiver signal strength and the remote control signal strength meet the first preset condition; if it is detected that the remote control receiver signal strength and the remote control signal strength meet the first preset condition, the vehicle controller detects whether the heartbeat signal meets the second preset condition; if the heartbeat signal meets the second preset condition, the vehicle controller controls the vehicle to decelerate and brake, which can give a warning and perform emergency braking before the remote control fails, greatly reducing the safety hazards caused by the loss of the remote control signal of the vehicle.
[0058] The embodiment of the present invention also provides a method for predicting in advance the failure of the vehicle remote control. The method for predicting in advance the failure of the vehicle remote control in the embodiment of the present invention is applied to the remote control. As shown in the appendix Figure 5 The method for predicting in advance the failure of the vehicle remote control includes:
[0059] Step S21: The remote control obtains in real time the remote control receiver signal strength and the remote control signal strength.
[0060] In an embodiment of the present invention, the remote controller receives the receiver feedback signal and the remote control signal strength sent by the receiver; the remote controller determines the remote controller received signal strength according to the receiver feedback signal, and the remote controller received signal strength is the signal strength of the receiver feedback signal.
[0061] Step S22: The remote controller determines whether the remote control fails according to the remote controller received signal strength and the remote control signal strength, and gives an alarm prompt according to the judgment result.
[0062] In an embodiment of the present invention, the remote controller respectively makes signal strength judgments on the remote controller received signal strength and the remote control signal strength; if it is judged that the remote controller received signal strength or the remote control signal strength is less than the first threshold and greater than the second threshold, the buzzer is controlled to give an alarm prompt at a preset frequency, where the second threshold is less than the first threshold. The preset frequency is preferably once per second, and of course it can also be set to other frequencies, which is not limited here. If it is judged that the remote controller received signal strength or the remote control signal strength is less than the second threshold, the buzzer is controlled to sound continuously. Both the first threshold and the second threshold can be set as needed. Preferably, the first threshold is 110 and the second threshold is 95.
[0063] In an embodiment of the present invention, the remote controller obtains the remote controller received signal strength and the remote control signal strength in real time; the remote controller determines whether the remote control fails according to the remote controller received signal strength and the remote control signal strength, and gives an alarm prompt according to the judgment result, which can give a warning and emergency braking before the remote controller fails, greatly reducing the safety hazards caused by the loss of the remote controller signal of the vehicle.
