Description

Technical Field

[0001] The present invention relates to the technical field of automotive engineering, and particularly to a convenient getting-on-and-off control method and device based on an air suspension. Background Art

[0002] As a key component of a vehicle chassis, the suspension system plays a crucial role in aspects such as the driving performance, riding comfort, and handling stability of the vehicle. The traditional passive suspension system has been widely used in the automotive industry for a long time due to its advantages such as simple structure, low cost, and high reliability. However, the traditional passive suspension system also has some obvious limitations, and one of them is that its height is not adjustable.

[0003] Since the height of the traditional passive suspension is fixed, it is difficult for the vehicle to adapt flexibly to different usage scenarios. For example, in the getting-on-and-off scenario, when the vehicle is parked by the roadside or in a relatively narrow space, passengers may feel inconvenient when getting on and off the vehicle because the ground clearance of the vehicle body is relatively high. Especially for people with mobility difficulties, the elderly, and children, the relatively high vehicle body height increases the difficulty of getting on and off the vehicle and may even pose a safety hazard. This non-adjustable height characteristic makes the traditional passive suspension have certain deficiencies in enhancing the user experience.

[0004] In contrast, as a new suspension technology, the air suspension system provides a new way to solve the above problems of the traditional passive suspension. The air suspension can flexibly control the height of the vehicle body by adjusting the air pressure in the air spring. When convenient getting on and off is required, the air suspension can lower the vehicle body height so that passengers can get in and out of the vehicle more easily and safely; during vehicle driving, the vehicle body height can be adjusted in a timely manner according to road conditions and driving requirements to optimize the driving performance and riding comfort of the vehicle.

[0005] However, the current convenient getting-on-and-off control methods for air suspensions are relatively scarce, unable to adjust the height of the vehicle air suspension according to different user needs, and it is difficult to meet the actual convenient getting-on-and-off needs of users.

[0032] In step S102, corresponding vehicle status data and the current air suspension height are collected according to the user's convenient getting-on-and-off request.

[0033] In some embodiments, collecting corresponding vehicle status data according to the user's convenient getting-on-and-off request includes:

[0034] When the user's convenient getting-on-and-off request is a manual convenient getting-on request, the current power status, the current air spring system status, the current electronic parking brake system status, and the current air suspension height are collected;

[0035] When the user's convenient getting-on-and-off request is a manual convenient getting-off request, the current power status, the current air spring system status, and the current air suspension height are collected;

[0036] When the user's convenient getting-on-and-off request is an automatic convenient getting-on request, the current power status, the current air spring system status, the current air suspension height, and the current electronic parking brake system status are collected;

[0037] When the user's convenient getting-on-and-off request is a manual convenient getting-off request and an automatic convenient getting-on request, the current power status, the current air spring system status, and the current air suspension height are collected.

[0038] During the actual execution process, when the user's convenient getting on / off request is a manual convenient getting-on request, vehicle status data such as the current power status, the current air spring system status, the current electronic parking brake system status, and the auxiliary passing signal, as well as the current air suspension height, are collected; when the user's convenient getting on / off request is a manual convenient getting-off request, vehicle status data such as the current power status, the current air spring system status, and the auxiliary passing signal, as well as the current air suspension height, are collected; when the user's convenient getting on / off request is an automatic convenient getting-on request, vehicle status data such as the current power status, the current air spring system status, the current electronic parking brake system status, the auxiliary passing signal, the vehicle non-collision signal, and the small battery SOC are collected, as well as the current air suspension height; when the user's convenient getting on / off request is a manual convenient getting-off request and an automatic convenient getting-on request, vehicle status data such as the current power status, the current air spring system status, the auxiliary passing signal, the vehicle non-collision signal, and the small battery SOC are collected, as well as the current air suspension height.

[0039] In step S103, the current air suspension height is adjusted to a preset convenient getting-on height gear or a preset convenient getting-off height gear according to the vehicle status data.

[0040] In some embodiments, adjusting the current air suspension height to a preset convenient getting-on / off height gear according to the vehicle status data includes:

[0041] When the user's convenient getting on / off request is a manual convenient getting-on request, if the current power status is a power-off state and the current electronic parking brake system status is on, the current air suspension height is adjusted to a preset convenient getting-on height gear according to the current air spring system status;

[0042] When the user's convenient getting on / off request is a manual convenient getting-off request, if the current power status is a low-voltage power status, the current air suspension height is adjusted to a preset convenient getting-off height gear according to the current air spring system status;

[0043] When the user's convenient getting on / off request is an automatic convenient getting-on request, if the current power status is a low-voltage power status, the current electronic parking brake system status is on, and a Bluetooth welcome activation signal or a Bluetooth proximity unlock request signal is received from the mobile device via Bluetooth, the current air suspension height is adjusted to a preset convenient getting-on height gear according to the current air spring system status;

[0044] In the case where the user's convenient getting on and off request is a manual convenient getting off request and an automatic convenient getting on request, the manual convenient getting off request is preferentially responded to. If the current power state is the power-off state and the current electronic parking brake system state is on, the current air suspension height is adjusted to the preset convenient getting on height gear according to the current air spring system state, and then the automatic convenient getting on request is responded to. If the current power state is the low-voltage power state, the current electronic parking brake system state is on, and a Bluetooth welcome activation signal or a Bluetooth proximity unlock request signal is received from the mobile terminal Bluetooth, the current air suspension height is adjusted to the preset convenient getting on height gear according to the current air spring system state.

[0045] In the actual execution process, in the case where the user's convenient getting on and off request is a manual convenient getting on request, if the current power state is the power-off state and the current electronic parking brake system state is on, it indicates that the vehicle is in the power-off and locked state. It is judged whether the current air suspension height is equal to the preset convenient getting on height gear. If the current air suspension height is equal to the preset convenient getting on height gear, the vehicle body height is maintained and the height state is continuously monitored. Otherwise, a solenoid valve drive signal is sent to the air suspension system according to the current air spring system state and the vehicle auxiliary passage signal, and the solenoid valves of the left front axle, left rear axle, right front axle, and right rear axle in the air spring are adjusted according to the solenoid valve drive signal, so that the current air suspension height is adjusted to the preset convenient getting on height gear to facilitate the user to get on the vehicle.

[0046] In the case where the user's convenient getting on and off request is a manual convenient getting off request, if the current power state is the low-voltage power state, it indicates that the vehicle is in a stationary state. It is judged whether the current air suspension height is equal to the preset convenient getting off height gear. If the current air suspension height is equal to the preset convenient getting off height gear, the vehicle body height is maintained and the height state is continuously monitored. Otherwise, a solenoid valve drive signal is sent to the air suspension system according to the current air spring system state and the vehicle auxiliary passage signal, and the solenoid valves of the left front axle, left rear axle, right front axle, and right rear axle in the air spring are adjusted according to the solenoid valve drive signal, so that the current air suspension height is adjusted to the preset convenient getting off height gear to facilitate the user to get off the vehicle.

[0047] When the user's convenient getting on and off request is an automatic convenient getting on request, if the low-voltage power supply state of the current power supply state, the current electronic parking brake system state is on, and a Bluetooth welcome activation signal or a Bluetooth proximity unlock request signal sent by the mobile terminal Bluetooth is received, it is determined whether the current air suspension height is equal to the preset convenient getting on height gear. If the current air suspension height is equal to the preset convenient getting on height gear, the vehicle body height is maintained and the height state is continuously monitored. Otherwise, according to the current air spring system state, the vehicle auxiliary passage signal, the vehicle non-collision signal, and the small battery SOC signal, an electromagnetic valve drive signal is sent to the air suspension system, and the electromagnetic valves of the left front axle, the left rear axle, the right front axle, and the right rear axle in the air spring are adjusted according to the electromagnetic valve drive signal, so that the current air suspension height is adjusted to the preset convenient getting on height gear to facilitate the user to get on the vehicle. And after the vehicle is at the convenient getting on height, it will simultaneously wait to execute the manual convenient getting off request.

[0048] When the user's convenient getting on and off request is a manual convenient getting off request and an automatic convenient getting on request, the manual convenient getting off request is preferentially responded to. If the current power supply state is a power-off state and the current electronic parking brake system state is on, an electromagnetic valve drive signal is sent to the air suspension system according to the current air spring system state and the vehicle auxiliary passage signal, and the electromagnetic valves of the left front axle, the left rear axle, the right front axle, and the right rear axle in the air spring are adjusted according to the electromagnetic valve drive signal, so that the current air suspension height is adjusted to the preset convenient getting on height gear; then the automatic convenient getting on request is considered. If the low-voltage power supply state of the current power supply state, the current electronic parking brake system state is on, and a Bluetooth welcome activation signal or a Bluetooth proximity unlock request signal sent by the mobile terminal Bluetooth is received, it is determined whether the current air suspension height is equal to the preset convenient getting on height gear. If the current air suspension height is equal to the preset convenient getting on height gear, the vehicle body height is maintained and the height state is continuously monitored. Otherwise, according to the current air spring system state, the vehicle auxiliary passage signal, the vehicle non-collision signal, and the small battery SOC signal, an electromagnetic valve drive signal is sent to the air suspension system, and the electromagnetic valves of the left front axle, the left rear axle, the right front axle, and the right rear axle in the air spring are adjusted according to the electromagnetic valve drive signal, so that the current air suspension height is adjusted to the preset convenient getting on height gear to facilitate the user to get on the vehicle. And after the vehicle is at the convenient getting on height, it will simultaneously wait to execute the manual convenient getting off request.

[0049] It should be noted that if the vehicle non-collision signal is no and / or the small battery SOC signal is insufficient in power, the air suspension height adjustment process cannot be executed, but a suspension man-machine interaction failure feedback signal is sent to the central control display screen or the mobile phone APP to issue a warning of inability to execute to the driver.

[0050] In some embodiments, it further includes:

[0051] Obtain the current vehicle speed and the adjusted air suspension height;

[0052] Adjust the adjusted air suspension height to the vehicle driving air suspension height according to the current vehicle speed or the difference between the current air suspension height and the adjusted air suspension height.

[0053] In the actual execution process, after the manual convenient boarding request is completed, obtain the current vehicle speed and the adjusted air suspension height. If the current vehicle speed > 5 km / h or the difference between the current air suspension height and the adjusted air suspension height is not equal to 0, the air suspension supply unit of the vehicle sends a manual convenient boarding feedback signal to the vehicle driving assistance system, and then the vehicle driving assistance system forwards it to the central control display screen or the mobile phone APP. After receiving the feedback signal, restore the manual convenient boarding soft switch to the state before activation, and adjust the adjusted air suspension height to the vehicle driving air suspension height.

[0054] After the manual convenient alighting request is completed, obtain the current vehicle speed and the adjusted air suspension height. If the current vehicle speed > 3 km / h or the difference between the current air suspension height and the adjusted air suspension height is not equal to 0, the air suspension supply unit of the vehicle sends a manual convenient alighting feedback signal to the vehicle driving assistance system, and then the vehicle driving assistance system forwards it to the central control display screen or the mobile phone APP. After receiving the feedback signal, restore the manual convenient alighting soft switch to the state before activation, and adjust the adjusted air suspension height to the vehicle driving air suspension height.

[0055] After the automatic convenient boarding request is completed, obtain the current vehicle speed and the adjusted air suspension height. If the current vehicle speed > 5 km / h or the difference between the current air suspension height and the adjusted air suspension height is not equal to 0, the air suspension supply unit of the vehicle sends an automatic convenient boarding feedback signal to the vehicle driving assistance system, and then the vehicle driving assistance system forwards it to the central control display screen or the mobile phone APP. After receiving the feedback signal, restore the automatic convenient boarding soft switch to the state before activation, and adjust the adjusted air suspension height to the vehicle driving air suspension height.

[0056] After the manual convenient alighting request and the automatic convenient boarding request are successively completed, obtain the current vehicle speed and the adjusted air suspension height. If the current vehicle speed > 5 km / h or the difference between the current air suspension height and the adjusted air suspension height is not equal to 0, the air suspension supply unit of the vehicle sends an automatic convenient boarding feedback signal to the vehicle driving assistance system, and then the vehicle driving assistance system forwards it to the central control display screen or the mobile phone APP. After receiving the feedback signal, restore the automatic convenient boarding soft switch to the state before activation, and adjust the adjusted air suspension height to the vehicle driving air suspension height.
