Technical Field

The invention relates to the technical field of vehicle body control, in particular to a method, a device and equipment for remotely adjusting the height of a vehicle body and a readable storage medium.

Background

Modern automobiles pay more and more attention to the riding experience of users, and the riding comfort of vehicles can be guaranteed through research and design of vehicle suspension systems. With the development of the electronic control air suspension technology, the function of the air suspension for controlling the height of the vehicle body by lifting the chassis is improved, and the comfort of the vehicle is further improved. The electronic control air suspension system is a complete pneumatic control system and comprises an air source device, a sensor, a control unit ECU, an execution element and a control element. The air source element generally comprises a compressor driven by a motor and used for compressing air to an air storage tank and inflating an air spring in the driving process, and the air storage tank stores dry air and is used for inflating the air spring to lift the height of the vehicle when the vehicle is static; the control element comprises a distribution valve, the distribution valve is a combined valve body, electromagnetic valves connected with the four air springs and the air storage tank through pipelines can be independently opened, and the air springs can be directly inflated and deflated by opening and closing the electromagnetic valves; the sensors generally include pressure and temperature sensors for detecting the state of the air supply, a vehicle height sensor for detecting the level of the vehicle body, and other vehicle state and control information such as ignition of an engine, acceleration of the vehicle, braking or steering, etc., which are generally obtained through a vehicle body controller via a CAN bus; the control unit ECU, namely the air suspension control unit, receives input information such as a motion mode and vehicle height selection from each sensor, a CAN bus and a driver, and controls the air storage tank and the air spring to be inflated and deflated after the information is processed.

The height adjustment of the vehicle body is a common function of an air suspension, when the height of the vehicle body needs to be increased, an inflation solenoid valve and a solenoid valve of an air spring are opened, high-pressure gas in a gas storage tank enters the air spring, and the volume of the air spring is enlarged, so that the height of the vehicle body is increased. When the height needs to be reduced, the air bleeding electromagnetic valve and the air spring electromagnetic valve are opened, air in the air spring is directly exhausted into the atmosphere, and the volume of the air spring is reduced, so that the height of the vehicle body is reduced. With the selection of more and more big off-road vehicles or SUV vehicles by users, and due to the fact that the chassis of the off-road vehicle is high and the threshold of getting on the vehicle is high, inconvenience is brought to drivers, old people or children with low height when getting on the vehicle. The air suspension of the existing vehicle can only adjust the height of the vehicle body of the whole vehicle by manually operating a driving mode key after a driver enters the vehicle, cannot adjust the height of the vehicle when the driver does not enter the vehicle, does not have the function of remotely adjusting the height of the vehicle body, and cannot improve the convenience of a user entering the vehicle for a large-scale SUV.

In a second aspect, the embodiment of the invention provides a method for remotely adjusting the height of a vehicle body.

Referring to fig. 2, fig. 2 is a schematic flow chart of an embodiment of a method for remotely adjusting the height of a vehicle body according to the present invention.

In an embodiment of the method for remotely adjusting the height of the vehicle body, the method for remotely adjusting the height of the vehicle body comprises the following steps:

step S10, when establishing Bluetooth connection with legal terminal, judging whether the vehicle satisfies the height descending condition;

in the embodiment, when the user is bound with the vehicle through the mobile phone APP and is successfully paired and connected with the vehicle through the mobile phone Bluetooth for the first time, the vehicle recognizes that the mobile phone, which is successfully connected with the vehicle through Bluetooth binding, of the user is a legal terminal. After the first pairing connection is completed, every time the user approaches an identification area of the vehicle bluetooth controller through the successfully paired mobile phone, for example, within a radius R of the vehicle, the vehicle bluetooth controller may be directly connected with the successfully paired mobile phone, i.e., bluetooth of a legal terminal. After the Bluetooth connection with the legal terminal is carried out, the vehicle-mounted Bluetooth controller sends a vehicle height descending request to the air suspension control unit through the CAN bus, and after the air suspension control unit receives the vehicle height descending request of the vehicle-mounted Bluetooth controller, the vehicle state is comprehensively judged whether to meet the vehicle height descending condition or not according to the received vehicle information sent by the vehicle controller through the CAN bus.

Further, in an embodiment, the step of determining whether the vehicle satisfies the altitude decrease condition includes:

judging whether the gas pressure value of the gas storage tank is larger than a preset pressure value, whether the vehicle is in a flameout and locked state and whether the vehicle is on a horizontal road surface;

if the gas pressure value of the gas storage tank is larger than the preset pressure value, the vehicle is in a flameout and locked state, and the vehicle is on a horizontal road surface, the vehicle meets the height descending condition;

if the gas pressure value of the gas storage tank is smaller than the preset pressure value, or the vehicle is not in a flameout state and is locked, or the vehicle is not in a horizontal road surface, the vehicle does not meet the height descending condition.

In this embodiment, after the air suspension control unit receives the vehicle height descending request from the vehicle-mounted bluetooth controller, it is comprehensively determined whether the vehicle state satisfies the vehicle height descending condition according to the received vehicle information sent by the vehicle controller through the CAN bus. The method comprises the steps of judging whether a vehicle meets a descending condition or not, and comprehensively judging whether the gas pressure value of a gas storage tank is larger than a preset pressure value or not, whether the vehicle is in a flameout and locked state or not and whether the vehicle is on a horizontal road surface or not. The air pressure in the air storage tank is collected by controlling a pressure sensor integrated in a distribution valve through a vehicle body controller, at the moment, the pressure value of the air pressure collected by the pressure sensor is greater than a preset pressure value, the fact that the air in the air storage tank is enough to inflate an air spring to support the height of the vehicle to rise from the height of the vehicle body to the original height is shown, and if the pressure value of the air pressure collected by the pressure sensor is smaller than the preset pressure value, the fact that the air in the air storage tank is not enough to inflate the air spring to support the height of the vehicle to rise from the height of the vehicle body to the original height is shown; meanwhile, whether the vehicle is in a flameout and locked state and whether the vehicle is on a horizontal road surface is judged according to the information of whether the vehicle door is locked state or not, the information of whether the vehicle is ignited and started state or not and the information of whether the vehicle is on the horizontal road surface or not in the vehicle body controller, if the condition that the height of the vehicle body is reduced needs to be met, the vehicle must be in a flameout and locked state, and the vehicle needs to be on the horizontal road surface so as to prevent the bottom knocking situation caused by the vehicle on the non-horizontal road surface. Therefore, when the air suspension control unit comprehensively judges that the air pressure value of the air storage tank is greater than the preset pressure value, the vehicle is in a flameout and locked state and the vehicle is in a horizontal road surface, the vehicle meets the height descending condition; when the air suspension control unit comprehensively judges that the air pressure value of the air storage tank is smaller than the preset pressure value, or the vehicle is not in a flameout state and is locked, or the vehicle is not in a horizontal road surface, the vehicle does not meet the height descending condition.

Further, in an embodiment, the step of determining whether the vehicle satisfies the altitude decrease condition further includes:

if the vehicle does not meet the height descending condition, keeping the height of the vehicle body unchanged;

and when the ignition start of the vehicle is recognized, outputting prompt information that the vehicle state does not meet the height descending condition.

In this embodiment, if the vehicle does not satisfy the height lowering condition after the air suspension control unit comprehensively determines that the vehicle does not satisfy the height lowering condition, the vehicle height is kept unchanged, and when it is recognized that the ignition of the vehicle is started, prompt information that the vehicle state does not satisfy the height lowering condition is output to prompt the user that the current vehicle state is not enough to lower the vehicle height to the target height set by the user.

Further, in an embodiment, the step of determining whether the vehicle is on a horizontal road surface includes:

acquiring transverse and longitudinal acceleration data of a vehicle through an acceleration sensor, and judging whether the acceleration data is smaller than a preset threshold value;

and if the acceleration data is smaller than a preset threshold value, judging that the vehicle is on a horizontal road surface.

In this embodiment, whether the vehicle is on a horizontal road surface can be judged by acquiring the transverse and longitudinal acceleration data of the vehicle through the acceleration sensor, for example, when the vehicle is on a slope road surface, or front and rear wheels of the vehicle are not on the same horizontal plane, the vehicle has a certain inclination relative to the horizontal plane, at this time, the horizontal and vertical components of the gravity acceleration of the vehicle exist in the transverse direction relative to the horizontal plane of the vehicle bottom and in the longitudinal direction relative to the vertical plane of the vehicle bottom, the preset threshold value is calculated and determined relative to the gravity acceleration of the vehicle and the preset inclination, when the transverse and longitudinal acceleration data of the vehicle are smaller than the preset threshold value, the air suspension control unit can judge that the vehicle is on the horizontal road surface, and the possibility of a bottom-knocking situation caused by the vehicle on a non-horizontal road surface does not exist.

Step S20, if the vehicle meets the height descending condition, controlling the air suspension to descend the height of the vehicle body from the original height to the target height;

in this embodiment, if the air suspension control unit comprehensively determines that the vehicle meets the height reduction condition, the air suspension control unit controls to open the air spring electromagnetic valve to deflate the air spring to reduce the height of the vehicle body from the original height to the target height corresponding to the legal terminal, and when the air suspension control unit identifies that the vehicle has fallen to the target height corresponding to the legal terminal through the vehicle body height sensor, the air suspension control unit closes the corresponding electromagnetic valve to stop deflating the air spring.

Further, in one embodiment, the step of controlling the air suspension to lower the vehicle body height from the original height to the target height comprises:

and controlling the air suspension to reduce the height of the vehicle body from the original height to the target height corresponding to the legal terminal.

In the embodiment, when different users approach the identification area of the vehicle Bluetooth controller through the mobile phone successfully paired, different users may like different boarding heights, the target height of the vehicle body CAN be customized through the users, different users CAN be paired and bound with the same vehicle through different mobile phone Bluetooth keys, and the users set the convenient boarding vehicle body target height on the mobile phone APP, so that the target heights corresponding to different legal terminals may be different, therefore, when the vehicle Bluetooth controller identifies different legal terminals, the vehicle Bluetooth controller CAN send different vehicle body height descending requests to the air suspension control unit through the CAN bus, and at this time, after the air suspension control unit receives the vehicle body height descending requests of the vehicle Bluetooth controller, according to the received vehicle information sent by the vehicle controller through the CAN bus, and comprehensively judging whether the vehicle state meets the vehicle body height descending condition or not. If the user 1 and the user 2 simultaneously carry the legal terminal 1 and the legal terminal 2 to enter the identification area of the vehicle Bluetooth controller, the vehicle is preferentially connected with the legal terminal 1 with the first priority according to the priority options of the legal terminals connected in a matched mode on the mobile phone APP, and if the legal terminal 1 is in the first priority and the legal terminal 2 is in the second priority, the vehicle is determined whether the vehicle meets the vehicle height reduction condition or not according to the vehicle target height 1 set by the legal terminal 1; and when the vehicle meets the condition of the height of the vehicle body to be lowered, controlling to open an air spring electromagnetic valve to deflate an air spring so as to lower the height of the vehicle body from the original height to the target height 1 corresponding to the legal terminal 1.

Step S30, determining whether the vehicle satisfies a height increasing condition;

in this embodiment, when it is determined that the vehicle meets the vehicle height descending condition, the vehicle is in a flameout and vehicle locking state and a horizontal road surface, at this time, the vehicle body has descended to a target height through the air suspension control unit, and then the vehicle body is at the target height at which the vehicle is conveniently loaded, and when all users who take the vehicle are loaded at the target height at which the vehicle is conveniently loaded, it is necessary to determine whether the vehicle meets the height ascending condition at this time.

Further, in an embodiment, the step of determining whether the vehicle satisfies the altitude rise condition includes:

judging whether the vehicle door is closed and whether the vehicle is ignited to start;

if the vehicle door is closed and the vehicle is ignited to start, the vehicle meets the height rising condition;

if the door is not closed or the vehicle is not ignited to start, the vehicle does not meet the height increasing condition.

In this embodiment, the determining whether the vehicle meets the height increasing condition includes determining whether a door of the vehicle is closed and whether the vehicle is ignited to start; if the vehicle door is closed and the vehicle is ignited and started, it is indicated that all users taking the vehicle get on the vehicle and the vehicle is in an ignition starting and departure state at the moment, and the vehicle meets the height rising condition; if the vehicle door is not closed or the vehicle is not ignited to start, the fact that the user who rides does not get on the vehicle at the moment is indicated, or the vehicle is not ignited to start currently, and the vehicle does not meet the height rising condition.

And step S40, if the vehicle meets the height rising condition, controlling the air suspension to restore the height of the vehicle body from the target height to the original height.

In this embodiment, if the vehicle meets the height increasing condition that the vehicle door is closed and the vehicle is ignited to start, the air suspension control unit controls to open the corresponding air storage tank and the corresponding electromagnetic valve to inflate the air spring, and controls the air suspension to restore the height of the vehicle body from the target height to the original height. The original height to which the vehicle is running while the vehicle is running on the road surface is restored at this time.

In the embodiment, when the Bluetooth connection is established with a legal terminal, whether the vehicle meets the height descending condition is judged; if the vehicle meets the height descending condition, controlling the air suspension to descend the height of the vehicle body from the original height to the target height; judging whether the vehicle meets a height rising condition or not; and if the vehicle meets the height rising condition, controlling the air suspension to restore the height of the vehicle body from the target height to the original height. When the vehicle is not powered on and started, the vehicle identifies a legal terminal through the vehicle-mounted Bluetooth controller, then according to a target height set by the legal terminal, whether the current pressure value of the air storage tank meets the condition that the height is recovered to the original height after the height is reduced to the target height is judged through the pressure sensor, whether the vehicle meets the information of flameout and vehicle locking states and whether the current vehicle is on a horizontal road surface is obtained through the vehicle body sensor received by the CAN bus, whether the height reduction condition is met is comprehensively judged according to the condition, when the height reduction condition is judged to be met, the air suspension control unit opens the air spring electromagnetic valve to deflate the air spring through control, so that the vehicle body height is reduced, the requirement of remotely adjusting the vehicle body height is met, and a user CAN conveniently set different vehicle body heights after the Bluetooth legal connection, so as to improve the convenience of getting on and taking by the user.
