Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a slope sensor calibration method, device, equipment and storage medium. Background Art

[0002] A slope sensor is a sensor that measures the tilt angle of an object. It is usually composed of two sensitive elements, each of which measures the tilt angle of the object in the x and y axes. These elements can be capacitors, resistors, piezoelectric bodies or MEMS (Micro-Electro-Mechanical System). When an object tilts, gravity will cause the sensitive element in one direction to be compressed and the sensitive element in the other direction to be stretched, which results in a difference in capacitance, resistance, voltage or current between the two elements. By measuring these differences, the tilt angle of the object can be determined; the slope sensor has high accuracy and sensitivity and can be used in a variety of environments.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The current vehicle slope sensor calibration method has the problem that the calibration process is cumbersome and it is easy to miss the calibration of the slope sensors of some vehicles. To this end, the present application provides a slope sensor calibration method that can complete the slope sensor calibration by operating the accelerator and brake, thereby improving the calibration efficiency.

[0038] See also Figure 1 As shown, an embodiment of the present invention discloses a slope sensor calibration method, including:

[0039] Step S11, placing a target vehicle on a target plane with a zero slope, and making the target vehicle powered on and the engine of the target vehicle not started, so as to obtain a target calibration state corresponding to the target vehicle.

[0040] In this embodiment, Figure 2 As shown, when a new vehicle rolls off the production line, the target vehicle, such as an electric heavy truck, needs to be placed on a target horizontal plane with zero slope first, and the key of the target vehicle needs to be turned to the non-READY state of the ON gear (i.e., the target vehicle is powered on and the engine of the target vehicle is not started), so that the target vehicle is powered on and the engine in the target vehicle is not started. It is understandable that after the new vehicle rolls off the production line, the slope sensor of the target vehicle is still in an uncalibrated state, and the slope sensor needs to be calibrated; and the initial calibration of the slope sensor must set the slope sensor to zero, so the target vehicle needs to be placed on a target plane with zero slope. It should be noted that the above target state also includes the gear position of the target vehicle being in neutral, and the handbrake of the target vehicle being in the pulled-up state; it is understandable that the operation of making the engine of the target vehicle in the off state, the handbrake in the pulled-up state, and the gear position in the neutral gear is to prevent the dangerous situation of the target vehicle moving uncontrollably after the sensor calibration personnel step on the brake. Before calibrating the slope sensor of the target vehicle, the gear position of the target vehicle is placed in neutral and the handbrake of the target vehicle is pulled up, thereby avoiding the dangerous situation of sudden movement of the vehicle and improving the safety of the slope sensor calibration process.

[0041] Step S12: When the target vehicle is in the target calibration state, read the dashboard of the target vehicle to obtain the current vehicle state displayed on the dashboard, and judge whether the current vehicle state displayed on the dashboard is correct based on the actual vehicle state of the target vehicle to obtain a corresponding first judgment result.

[0042] In this embodiment, it is necessary to determine whether the current vehicle loading displayed on the vehicle's instrument panel is correct. For example, in one specific embodiment, if the current state of the handbrake is pulled up, and the instrument panel shows that the handbrake of the current vehicle is not pulled up, it is determined that the current vehicle state displayed on the instrument panel is wrong, and accordingly, a first judgment result indicating that the current vehicle state is displayed incorrectly is obtained; in another specific embodiment, if the gear of the current vehicle has been placed in neutral, and the instrument panel shows that the gear of the current vehicle has not been placed in neutral, it is determined that the current vehicle state displayed on the instrument panel is wrong, and accordingly, a first judgment result indicating that the current vehicle state is displayed incorrectly is obtained; in a third specific embodiment, if the current vehicle state displayed on the instrument panel is consistent with the actual vehicle state, it is determined that the current vehicle state displayed on the instrument panel is correct, and accordingly, a first judgment result indicating that the current vehicle state is displayed correctly is obtained. In this embodiment, by determining the vehicle state displayed on the vehicle's instrument panel, it is ensured that the vehicle state is consistent with the actual state, thereby ensuring that the vehicle does not have an abnormal state before the vehicle's slope sensor is calibrated, thereby improving the reliability of the sensor calibration process.

[0043] Step S13: according to the first judgment result, the accelerator and the brake of the target vehicle are placed at the target position and maintained for a preset time period to calibrate the slope sensor of the target vehicle.

[0044] In this embodiment, the process of placing the throttle and brake of the target vehicle at the target position and maintaining them for a preset time period according to the first judgment result specifically includes: if the first judgment result indicates that the current vehicle state displayed on the instrument panel is correct, then directly placing the throttle and brake of the target vehicle at the target position and maintaining them for the preset time period, for example, the throttle and brake can be pressed to the bottom at the same time and maintained in this state for 30 seconds; if the first judgment result indicates that the current vehicle state displayed on the instrument panel is incorrect, then jumping to the step of placing the target vehicle on a target plane with zero slope, and making the target vehicle in a powered-on state and the engine of the target vehicle in an unstarted state to obtain a target calibration state corresponding to the target vehicle, so as to obtain a new vehicle state corresponding to the target vehicle, and based on the new vehicle state, placing the throttle and brake of the target vehicle at the target position and maintaining them for the preset time period. It can be understood that if the first judgment result indicates that the current vehicle status displayed on the instrument panel is incorrect, then the target vehicle currently has a system failure, which may affect the subsequent calibration process of the slope sensor. In this case, the target vehicle needs to be re-placed on a horizontal plane with zero slope and the target vehicle needs to be adjusted again so that the target vehicle is in the above-mentioned target calibration state. After the target vehicle is in the above-mentioned target calibration state, it is determined again whether the current vehicle status displayed on the instrument panel is correct. If the current vehicle status displayed on the instrument panel is correct, it means that the target vehicle does not have a system failure that will affect the calibration process.

[0045] In this embodiment, after the accelerator and brake of the target vehicle are placed in the target position and maintained for a preset time period, it also includes: stopping the target vehicle, and restarting the target vehicle after a preset time interval, so as to update the display data of the instrument panel of the target vehicle. It should be noted that after the accelerator and brake of the target vehicle are placed in the preset position for a target time period, the automatic calibration function of the vehicle's slope sensor has been activated. At this time, the slope sensor begins to automatically calibrate. To ensure that the slope sensor reading on the instrument panel has been updated, it is necessary to stop the target vehicle and restart the target vehicle after a preset time period, for example, 20 seconds. By restarting the target vehicle, it is ensured that the vehicle's instrument panel reading has been updated, avoiding the problem of misidentifying the slope sensor calibration failure due to the instrument panel reading not being updated even though the slope sensor has been calibrated, thereby improving the reliability of the slope sensor calibration process.

[0046] Step S14: using the instrument panel to determine whether the uncalibrated fault of the slope sensor disappears, and completing the calibration of the slope sensor of the target vehicle based on the corresponding second judgment result.

[0047] In this embodiment, the process of completing the calibration of the slope sensor of the target vehicle using the second judgment result specifically includes: if the second judgment result indicates that the uncalibrated fault of the slope sensor has not disappeared, jumping to the step of placing the throttle and brake of the target vehicle at the target position and maintaining them for a preset time period to calibrate the slope sensor of the target vehicle to complete the calibration of the slope sensor of the target vehicle; if the second judgment result indicates that the uncalibrated fault of the slope sensor has disappeared, it is determined that the calibration of the slope sensor of the target vehicle has been completed. It is understandable that after the slope sensor calibration is completed, under normal circumstances, the dashboard will display that the slope sensor is not calibrated fault has disappeared. If the accelerator and brake are placed in the target position at the same time and maintained for a preset time period, and the French dashboard still displays the vehicle's uncalibrated fault after the vehicle is restarted, it proves that the vehicle's slope sensor has not been calibrated successfully. Accordingly, the accelerator and brake are placed in the target position at the same time and maintained for a preset time period, and it is determined again whether the vehicle slope sensor uncalibrated fault displayed on the dashboard has disappeared, until the dashboard displays that the slope sensor is not calibrated fault has disappeared. At this time, it can be determined that the vehicle's slope sensor has been calibrated. By checking whether the slope uncalibrated fault displayed on the dashboard still exists, it is ensured that the slope sensor can eventually complete the calibration, avoiding the occurrence of missed calibration, and improving the reliability of the calibration process.

[0048] It can be seen that the embodiment of the present application avoids the dangerous situation of sudden movement of the vehicle by putting the gear position of the target vehicle in neutral and pulling up the handbrake of the target vehicle, thereby improving the safety of the slope sensor calibration process; by judging the vehicle status displayed on the vehicle's dashboard, it ensures that the vehicle status is consistent with the actual status, thereby ensuring that there is no abnormal state of the vehicle before the slope sensor of the vehicle is calibrated, thereby improving the reliability of the sensor calibration process; by checking whether the slope uncalibrated fault displayed on the dashboard still exists, it is ensured that the slope sensor can eventually complete the calibration, avoiding the occurrence of missed calibration, and improving the reliability of the calibration process.
