[0002] With more and more vehicle models starting to be equipped with air suspensions, the calibration of the height sensor in the air suspension directly affects the adjustment accuracy of the suspension height, and further affects the attitude of the vehicle, the comfort and the control safety.

[0024] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which like or similar elements or components are denoted throughout by like reference characters, and wherein the embodiments described below are illustrative of the principles of the present application, and are not intended to limit the application.

[0025] The method, device, and vehicle for reminding of non-calibration of an air suspension height sensor according to embodiments of the present application are described below with reference to the accompanying drawings. In view of the above background art, the present application provides a method for reminding of non-calibration of an air suspension height sensor, in which the method determines whether the circuit state is an open circuit state, or whether the angle value is less than a first preset working angle value, or whether the angle value is greater than a second preset working angle value. If the circuit state is an open circuit state, or the angle value is less than the first preset working angle value, or the angle value is greater than the second preset working angle value, it is determined that the height sensor is in a calibration state, and a first reminder signal is generated according to the calibration state and sent to a preset terminal. Thus, the vehicle equipped with an air suspension in the after-sales process forgets to calibrate the sensor height due to disassembly and replacement of the height sensor and its associated system components, and timely reminds the after-sales personnel and users to calibrate the sensor height, thereby avoiding the vehicle risk caused by the non-calibration of the height sensor in the after-sales process.

[0026] Specifically, Figure 1 A flowchart of a method for reminding of non-calibration of an air suspension height sensor according to an embodiment of the present application.

[0027] As Figure 1 shown, the air suspension height sensor uncalibrated reminding method comprises the following steps:

[0028] In step S101, the circuit state and angle value of the height sensor are acquired.

[0029] Optionally, in some embodiments, acquiring the circuit state and angle value of the height sensor comprises: acquiring a pulse width modulation (PWM) signal value and a voltage value of the height sensor; converting the PWM signal value of the height sensor based on a preset conversion strategy to obtain the angle value, and obtaining the circuit state according to the voltage value.

[0030] Specifically, as Figure 2 shown, in the hard-wired signal receiving process of the embodiment, the air suspension controller acquires the PWM signal value and voltage value of the height sensor, and converts the PWM signal value of the height sensor into the current angle value based on the preset conversion strategy in the related art.

[0031] In step S102, it is determined whether the circuit state is an open circuit state, or whether the angle value is less than a first preset working angle value, or whether the angle value is greater than a second preset working angle value, wherein the second preset working angle value is greater than the first preset working angle value.

[0032] In some embodiments, determining whether the circuit state of the height sensor is an open circuit state comprises: determining whether the PWM signal value is greater than a preset signal value and whether the voltage value is greater than a preset voltage value; if the PWM signal value is greater than the preset signal value and the voltage value is greater than the preset voltage value, it is determined that the circuit state is an open circuit state.

[0033] The preset signal value and the preset voltage value can be a threshold value preset by a user, a threshold value obtained through a finite number of experiments, or a threshold value obtained through a finite number of computer simulations, and is preferably set to 95%.

[0034] Specifically, the air suspension controller determines whether the circuit state of the height sensor is an open circuit state based on the acquired PWM signal value and voltage value. If the PWM signal value of the height sensor is greater than 95% and the instantaneous voltage exceeds the threshold value of the normal working voltage (i.e., the preset voltage value), it is determined that the height sensor is in an open circuit state.

[0035] In step S103, if the circuit state is an open circuit state, or the angle value is less than the first preset working angle value, or the angle value is greater than the second preset working angle value, it is determined that the height sensor is in a calibration pending state, a first reminding signal is generated according to the calibration pending state, and the first reminding signal is sent to a preset terminal.

[0036] The first preset working angle value can be understood as an angle value when the height sensor is in minimum working state, and the second preset working angle value can be understood as an angle value when the height sensor is in maximum working state.

[0037] The preset terminal includes, but is not limited to, a smart phone, a tablet computer, a PDA, and other terminal devices with a data processing function. Generally, the preset terminal refers to a terminal device with an independent operating system, which can install software, games, and programs provided by a third party service provider by the user, continuously expand the function of the handheld device through such programs, and realize wireless network access through a mobile communication network.

[0038] In the working condition judgment process, if the air suspension controller judges that the circuit state of the height sensor is in an open circuit state, it is determined that the height sensor is in a calibration standby state; if the air suspension controller judges that the angle value of the height sensor is less than the first preset working angle value, it is determined that the height sensor is in a calibration standby state; if the air suspension controller judges that the angle value of the height sensor is greater than the second preset working angle value, it is determined that the height sensor is in a calibration standby state, and a first reminder signal is generated according to the calibration standby state, and the first reminder signal is sent to the preset terminal to remind the user that the height sensor is in an uncalibrated state.

[0039] Further, in some embodiments, after determining that the height sensor is in a calibration standby state, it includes: generating a second reminder signal according to the calibration standby state, wherein the second reminder signal includes an optical reminder signal and / or an acoustic reminder signal; based on the optical reminder signal and / or the acoustic reminder signal, controlling the current vehicle to perform optical reminding and / or acoustic reminding.

[0040] Specifically, in the human-computer interaction reminding process, the air suspension controller generates a second reminder signal according to the calibration standby state and sends it to the current vehicle. After the instrument of the current vehicle receives the second reminder signal, a text pop-up window "please confirm that the height sensor has been calibrated" is generated based on the optical reminder signal, and a "drip-drip-drip" simulation prompt sound is emitted based on the acoustic reminder signal, thereby reminding or reminding the after-sales personnel that the height sensor is in a calibration standby state.

[0041] Further, in some embodiments, after sending the first reminder signal to the preset terminal, it further includes: judging whether a calibration instruction of the user is received; if the calibration instruction is received, the reminder signal is cleared.

[0042] The reminder signal includes the first reminder signal and the second reminder signal.

[0043] Specifically, in the elimination process of the human-computer interaction reminder, if the after-sales personnel has calibrated the height sensor, a calibration instruction is sent to a preset terminal, and if the calibration instruction is received, the after-sales personnel eliminates the first reminder signal and the second reminder signal through a diagnostic instrument, so that the vehicle returns to a normal driving state.

[0044] The air suspension height sensor uncalibration reminding method provided in the embodiments of the present application solves the problems of vehicle driving risks caused by forgetting to calibrate the height sensor during the after-sales process due to disassembly and replacement of the height sensor and its associated system components, reminds the after-sales personnel and the user to calibrate the height sensor in a timely manner, thereby avoiding the vehicle driving risks caused by the uncalibration of the height sensor during the after-sales process, does not need to increase additional hardware costs, the identification factors can cover all sensor replacement scenarios, the false positive probability is low, the feedback to the human-computer interaction interface can be timely, and the response is more timely.

[0045] Secondly, the air suspension height sensor uncalibration reminding device provided in the embodiments of the present application is described with reference to the accompanying drawings.

[0046] Figure 3 FIG. 1 is a block schematic diagram of the air suspension height sensor uncalibration reminding device according to the embodiments of the present application.

[0048] The acquisition module 100 is configured to acquire the circuit state and the angle value of the height sensor.The judgment module 200 is configured to judge whether the circuit state is in an open circuit state, or whether the angle value is less than a first preset working angle value, or whether the angle value is greater than a second preset working angle value. The reminding module 300 is configured to determine that the height sensor is in a calibration pending state if the circuit state is in the open circuit state, or the angle value is less than the first preset working angle value, or the angle value is greater than the second preset working angle value, generate a first reminder signal according to the calibration pending state, and send the first reminder signal to a preset terminal.

[0049] Optionally, in some embodiments, after determining that the height sensor is in the calibration pending state, the reminding module 300 is further configured to: generate a second reminding signal according to the calibration pending state, wherein the second reminding signal comprises an optical reminding signal and / or an acoustic reminding signal; and control the current vehicle to perform optical reminding and / or acoustic reminding based on the optical reminding signal and / or the acoustic reminding signal.

[0050] Optionally, in some embodiments, the acquisition module 100 is further configured to: acquire a pulse width modulation (PWM) signal value and a voltage value of the height sensor; and convert the PWM signal value of the height sensor to obtain an angle value and a circuit state according to the voltage value based on a preset conversion strategy.

[0051] Optionally, in some embodiments, the determination module 200 is further configured to: determine whether the PWM signal value is greater than a preset signal value and whether the voltage value is greater than a preset voltage value; and determine that the circuit state is in an open circuit state if the PWM signal value is greater than the preset signal value and the voltage value is greater than the preset voltage value.

[0052] Optionally, in some embodiments, after sending the first reminding signal to the preset terminal, the reminding module 300 is further configured to: determine whether a calibration instruction of a user is received; and clear the reminding signal if the calibration instruction of the user is received.

[0053] It should be noted that the foregoing explanation and description of the air suspension height sensor calibration pending reminding method embodiments are also applicable to the air suspension height sensor calibration pending reminding device of this embodiment, which will not be described herein again.
