Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, an embodiment of the present invention discloses a vehicle control method, including:
step S01: a state parameter of the vehicle is obtained.
Step S02: and controlling a radio frequency signal receiving module on the vehicle to enter a corresponding working mode according to the state parameter.
Specifically, the embodiment of the invention defines a plurality of working modes for the radio frequency signal receiving module, so that the radio frequency signal receiving module has at least one low-power-consumption mode besides a normal mode, namely a normal mode, and then the radio frequency signal receiving module is prevented from being continuously kept in the normal mode with high power consumption by switching the working modes of the radio frequency signal receiving module, the power consumption of a vehicle is reduced, and the power feeding prevention capability of the vehicle is improved.
The embodiment of the invention is applied to the vehicle body controller, and the vehicle body controller controls the radio frequency signal receiving module to enter corresponding working modes according to the state parameters of the vehicle based on a preset program and controls which functions of the radio frequency signal receiving module are started in different working modes.
The radio frequency signal receiving module supports various functions, and common functions include a remote unlocking function, a keyless entry function, a one-key starting function, a tire pressure receiving function and the like. The remote unlocking function refers to that a key of a vehicle is pressed to unlock the vehicle, namely, the vehicle key is pressed to send a radio frequency signal (carrying authentication information) with a certain frequency band to prove validity, so that normal unlocking of the vehicle is completed. The keyless entry function is to carry a vehicle key (without pressing the key of the vehicle), and when a vehicle enters an area after calibration, the vehicle enters by touching a door handle unlocking sensor. The one-key starting function is to carry a vehicle key (without pressing the key of the vehicle), and press an ignition switch in a calibrated vehicle starting area (in-vehicle area) to realize vehicle starting. The tire pressure receiving function is used for receiving and analyzing radio frequency signals transmitted by the four-wheel tire pressure sensor of the vehicle.
When the radio frequency signal receiving module is in the normal mode, all functions supported by the radio frequency signal receiving module are all started, and radio frequency signals are periodically received. For example, for a certain test vehicle a, the radio frequency signal receiving module is set to support the remote unlocking function, the keyless entry function, the one-key starting function and the tire pressure receiving function in the normal mode, and the radio frequency signal receiving module is set to receive a signal frame every 3ms in the normal mode, and at this time, the static current of the radio frequency signal receiving module in the normal mode is measured to be about 30mA.
One low power mode of the rf signal receiving module is a polling (polling) mode. When the vehicle body controller detects that the state parameters of the vehicle meet a first preset condition (the state parameters of the vehicle comprise a vehicle lock state, for example, and when the vehicle lock state is a vehicle fortification state, the state parameters of the vehicle are judged to meet the first preset condition, and the fortification state is a state that the vehicle is completely locked, the vehicle is in a security state and the property in the vehicle is protected), the radio frequency signal receiving module is controlled to be switched from a normal mode to a polling mode. When the radio frequency signal receiving module is in the polling mode, all functions supported by the radio frequency signal receiving module are all periodically turned on and off. For example, for the test vehicle a, four functions of the radio frequency signal receiving module may be set to be turned on at intervals of 30ms (configured according to a front end code of the RKE radio frequency protocol) in the polling mode, the turn-on time is 3ms, whether a radio frequency signal needs to be received is determined during the turn-on time, and after the radio frequency signal receiving module enters the polling mode, the TPMS (Tire Pressure Monitoring System, tire air pressure monitoring system) sends a radio frequency signal every 1 hour, and at this time, the static current of the radio frequency signal receiving module in the polling mode is measured to be less than 3mA.
The static current of the radio frequency signal receiving module in the polling mode is obviously smaller than that of the radio frequency signal receiving module in the normal mode, so that the power consumption of the radio frequency signal receiving module in the polling mode is obviously smaller than that of the radio frequency signal receiving module in the normal mode, the total electric quantity consumption of a vehicle can be reduced by switching the working modes of the radio frequency signal receiving module, and the power-preventing capability of the vehicle is improved. When the vehicle enters the anti-theft state, the radio frequency signal receiving module is controlled to exit the polling mode and restore to the normal mode.
In one example, a method flowchart of a vehicle body controller controlling a radio frequency signal receiving module to switch between a normal mode and a polling mode is shown in fig. 2, including:
step S11: the state parameters of the vehicle are acquired, and then the process proceeds to step S12.
Step S12: judging whether the vehicle enters a fortification state according to the state parameters, if so, entering a step S13; if not, return to step S11.
Step S13: the radio frequency signal receiving module is controlled to switch from the normal mode to the polling mode, and then step S14 is entered.
Step S14: judging whether the vehicle enters a disarmed state, if so, entering a step S15; if not, return to step S14.
Step S15: and (5) returning to the normal mode, and ending the control of the present wheel.
Optionally, based on any embodiment disclosed above, the further low power mode of the radio frequency signal receiving module is a transport mode.
Specifically, when the state parameter meets a second preset condition, the radio frequency signal receiving module is controlled to be switched from the normal mode to the transportation mode. When the radio frequency signal receiving module is in a transportation mode, the radio frequency signal receiving module only keeps the basic functions to be started, and the rest functions are all closed. For example, when the vehicle is in a transportation process from the production line, in the first preset mileage, the vehicle power supply is in the ON gear, and the vehicle can be controlled to enter the transportation mode by long-pressing preset keys ON the steering wheel (for example, long-pressing a steering wheel switch "volume down" and a "next curve" key for more than 5 s). For example, for the test vehicle a, only the one-key start function of the rf signal receiving module is kept on in the transport mode, and the quiescent current of the rf signal receiving module in the transport mode is measured to be less than 2mA.
After the transportation process is finished, triggering the radio frequency signal receiving module to exit the transportation mode, and recovering to the normal mode, wherein the exit conditions are as follows: the automatic exit is performed when a preset button on the steering wheel is pressed again for longer than a preset time (e.g., by manually triggering the long-press steering wheel switch "volume down" and "next curve" button for longer than 5 s) or when the vehicle mileage exceeds a second preset mileage (e.g., 50 Km).
In one example, a method flowchart of a vehicle body controller controlling a radio frequency signal receiving module to switch between a normal mode and a transport mode is shown in fig. 3, including:
step S21: the state parameters of the vehicle are acquired, and then the process proceeds to step S22.
Step S22: judging whether the condition parameters meet the following conditions: the vehicle mileage is less than the first preset mileage, and the duration of pressing a preset button on the steering wheel exceeds the preset duration; if yes, go to step S23; if not, return to step S21.
Step S23: the radio frequency signal receiving module is controlled to switch from the normal mode to the transport mode, and then step S24 is entered.
Step S24: judging whether the following conditions are satisfied: the duration that the preset key on the steering wheel is pressed again exceeds the preset duration, or the driving mileage of the vehicle exceeds the second preset mileage; if yes, go to step S25; if not, return to step S24.
Step S25: and (5) returning to the normal mode, and ending the control of the present wheel.
Optionally, based on any embodiment disclosed above, the further low power mode of the radio frequency signal receiving module is a marine mode.
Specifically, as part of vehicles have maritime requirements and the maritime time period is generally longer, the embodiment of the invention also defines the maritime mode for safety in consideration of the fact that the transportation mode still has certain power consumption. When the vehicle is in a third preset state (for example, a first trigger instruction issued by diagnostic equipment of the vehicle is received), the vehicle body controller executes a preset action, the radio frequency signal receiving module is switched from a normal mode to a marine mode after detecting that the preset action is executed successfully, namely, all functions supported by the radio frequency signal receiving module are closed, and only a main control unit, namely a main MCU, of the radio frequency signal receiving module is reserved to work. The preset actions include, for example: the standby power supply of the radio frequency signal receiving module is disconnected (the radio frequency signal receiving module adopts a dual-power supply design, one path is common power, the other path is standby power, the system reliability is ensured), and an enabling signal is sent to the radio frequency signal receiving module. For the test vehicle A, the static current of the radio frequency signal receiving module is small and can be basically ignored when the test vehicle A is measured in the marine mode. After the vehicle is transported to a destination by sea, the vehicle can exit the sea mode again through the diagnosis equipment, and the normal working mode is restored.
In one example, a method flowchart of a vehicle body controller controlling a radio frequency signal receiving module to switch between a normal mode and a polling mode is shown in fig. 4, including:
step S31: the state parameters of the vehicle are acquired, and then the process proceeds to step S32.
Step S32: judging whether a first trigger instruction issued by diagnostic equipment of the vehicle is received or not according to the state parameters, if so, entering step S33; if not, return to step S31.
Step S33: the standby power supply in the dual power supply of the radio frequency signal receiving module is disconnected, and an enabling signal is sent to the radio frequency signal receiving module, at this time, the radio frequency signal receiving module is switched from the normal mode to the marine mode, and then step S34 is performed.
Step S34: judging whether a second trigger instruction issued by the diagnostic equipment is received, if so, entering step S35; if not, return to step S34.
Step S35: and switching on the standby power supply in the dual-power supply of the radio frequency signal receiving module, stopping sending the enabling signal to the radio frequency signal receiving module, and recovering the radio frequency signal receiving module to the normal mode at the moment, so that the control of the round is finished.
The radio frequency signal receiving module on a vehicle can integrate a normal mode, a polling mode, a transportation mode and a marine mode at the same time, for example: the method shown in fig. 2, 3 and 4 can be included simultaneously, and in the system architecture, as shown in fig. 5, the vehicle body controller is respectively connected with the radio frequency signal receiving module, the diagnosis device, the steering wheel switch and the radio frequency signal receiving module standby electric switch BAT. The vehicle body controller is also connected to the enabling signal end of the radio frequency receiving module. The vehicle body controller CAN realize the switching between a normal mode and a polling mode and the switching between the normal mode and a transportation mode by carrying out CAN bus communication with the radio frequency signal receiving module; the vehicle body controller can disconnect the standby electric switch BAT and send an enabling signal to the radio frequency signal receiving module when receiving a first trigger instruction issued by the diagnostic equipment so as to trigger the radio frequency signal receiving module to realize switching from a normal mode to a marine mode. The switching condition from the normal mode to the marine mode is designed more complicated, mainly to avoid false triggering of the marine mode.
In addition, considering that the radio frequency signal receiving module generally works at the fixed frequency 433.92MHz, the possibility of functional failure caused by interference of signals in the same frequency band of the external environment exists, so that the anti-interference capability of the radio frequency signal receiving module is improved. Based on any embodiment disclosed above, the embodiment of the invention sets the radio frequency transmission and reception to adopt the frequency hopping technology (in the radio communication process, the radio frequency is within a certain range, and the transmission mode of hopping is polled according to a certain rule), so that the occurrence of the interference of radio frequency signals in the same frequency band in the external environment can be greatly reduced, the occurrence of the problems of remote control failure, tire pressure non-display and the like caused by the same frequency interference is reduced, and the reliability of the vehicle is improved.
For example, the radio frequency signal adopts micro frequency hopping technology, for example, cycle hopping is performed among 433.42MHz, 433.92MHz and 434.42MHz, and each time the key of the vehicle is pressed, the cycle hopping is completed, 6 frames of data are transmitted in total, and when the key is always effective, the remote control signal is continuously transmitted in the manner. The longest sending time of the key high-frequency signal is 20s (configurable), and after the longest sending time exceeds 20s, the built-in software of the key can automatically turn off high-frequency emission, so that the conditions of abnormal power consumption and the like caused by key locking are prevented. Under the micro-hopping technique, the transmission format of the radio frequency signal is shown in table 1 below:
TABLE 1
| Frequency band | Message number |
| 433.42 |
2 frames |
| 433.92 |
2 frames |
| 434.42 |
2 frames |
The corresponding diagram of table 1 is shown in fig. 6 (T in fig. 6 represents one micro-hop period).
Correspondingly, under the micro-hopping technique, the rf signal receiving channels are all open, as shown in table 2 below.
TABLE 2
| Receiving channel | Receiving channel A | Receiving channel B | Receiving channel C |
| Reception frequency | 433.42MHz | 433.92MHz | 434.42MHz |
In addition, the embodiment of the invention also discloses a vehicle body controller, which comprises: a processor and a memory having stored thereon a program which when executed by the processor implements any of the vehicle control methods as disclosed above.
In addition, the embodiment of the invention also discloses a vehicle, which comprises the following components: such as any of the vehicle body controllers disclosed above.
Optionally, for the vehicle, the vehicle key and a radio frequency signal receiving module on the vehicle adopt a micro-tuning technology to perform radio frequency communication, and when the duration of the radio frequency signal sent by the vehicle key exceeds a threshold value, the vehicle key automatically turns off the emission of the radio frequency signal.
