[0025] The present application is further described in detail below in conjunction with the embodiments and drawings. It is to be understood that the specific embodiments described herein are only used to explain the relevant application, rather than to limit the application. It is also necessary to explain that, for ease of description, only the parts related to the application are shown in the drawings.

[0026] It should be noted that, in the absence of conflict, the embodiments of the present application, that is, the features of the embodiments, can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] The following describes in detail the smart key of a vehicle and the vehicle according to an embodiment of the present application in conjunction with the accompanying drawings.

[0028] Figure 1 FIG. 1 is a schematic diagram of a smart key for a vehicle according to an embodiment of the present application. Figure 1 As shown, the smart key of the vehicle according to the embodiment of the present application includes: a front housing 110, a rear housing 120, an ECAS function button 130 and a Bluetooth chip ( Figure 1 ). Where:

[0029] The front housing 110 and the rear housing 120 form the housing of the smart key. The front housing 110 is provided with a key function area and an ECAS function area. The key function area is provided with a key function button 140. The ECAS function button 130 is provided in the ECAS function area. A Bluetooth chip is provided in the housing to send trigger signals from the key function button 140 and the ECAS function button 130 to the vehicle end.

[0030] Combination Figure 1 and Figure 2As shown, the ECAS function area includes an ECAS function button area and an ECAS indicator area, the ECAS function button 130 is located in the ECAS function button area, and the ECAS indicator area is provided with an ECAS indicator light 150. The ECAS indicator area, the key function area and the ECAS function button area are sequentially distributed from top to bottom on the front housing.

[0031] In this example, the ECAS function buttons include at least a first user memory mode (ie, user memory 1), an up button, a second user memory mode (ie, user memory 2), a mode selection left button, a stop button, a mode selection right button, and a down button.

[0032] Specifically, the vehicle is, for example, a bus or a truck, etc. The vehicle is equipped with a PEPS system (Passive Entry Passive Start) and an ECAS system (electronic-controlled air suspension for buses / trucks).

[0033] In other words, the ECAS remote control button is integrated into the smart key. Figure 2 As shown, the ECAS function button area on the smart key is provided with a plurality of buttons (i.e., ECAS function button 130) and a key function button 140. The key function button 140 generally refers to a traditional door unlocking, locking, and car search button on a key. In addition, the smart key of the embodiment of the present application is also integrated with a key function button 140, such as Figure 2 As shown, the key function button 140 may specifically include but is not limited to: user memory 1, up, user memory 2, mode selection left, stop, mode selection right, down, etc. Of course, it may also include an ECAS indicator light 150. Figure 2 As shown, from left to right and from top to bottom, they are: unlock, lock, find car, user memory 1, rise, user memory 2, mode selection left, stop, mode selection right, and lowering button.

[0034] Combination Figures 1 to 3 As shown, the smart key of the vehicle further includes: a sliding cover 160, the sliding cover 160 is arranged on the front housing 110, and the sliding cover 160 can slide up and down along the front housing 110 to a first position and a second position. When the sliding cover 160 slides to the first position, the sliding cover 160 covers the ECAS function button, and when the sliding cover 160 slides to the second position, the ECAS function button is exposed. When the sliding cover 160 slides to the first position, the schematic diagram of the smart key is as shown in FIG. Figure 3 As shown, when the sliding cover 160 slides to the second position, the schematic diagram of the smart key is as shown in Figure 2 shown.

[0035] In this example, if Figure 1 As shown, a sliding mechanism is provided on the front housing 110, and the sliding cover 160 is mounted on the sliding mechanism to slide up and down along the sliding mechanism. Figure 1 The slide cover 160 is buckled on the front housing 110 and slides up and down through the slide groove 170 on the front housing 110. When the slide cover 160 slides to the upper side (i.e., the first position), the ECAS function button 130 is blocked, thereby preventing the relevant functions of the ECAS system from being opened by mistake through the smart key; when the slide cover 160 slides to the lower side, the ECAS function button is exposed, and the ECAS function button 130 can be operated at this time to achieve the relevant function adjustment of the ECAS system.

[0036] like Figure 1 As shown, in the smart key of the vehicle, a mechanical key hole is formed on the housing, and the smart key of the vehicle further comprises: a mechanical key 180, and the mechanical key 180 is pluggable and disposed in the mechanical key hole. Figure 1 and Figure 4 As shown, the smart key of the vehicle further includes: a key hanging hole 190, and the key hanging hole 190 is arranged on the shell.

[0037] The smart key of the embodiment of the utility model has an ECAS indicator light on the top of the front shell, a door unlocking, locking and car search button in the middle, and an ECAS function button on the bottom, and the ECAS function button area can be covered by a sliding cover to achieve the function of preventing the ECAS function button from being accidentally touched. The mechanical key can be inserted into the mechanical key hole formed by the front and rear shells. If the mechanical key is needed to open or lock the door, the mechanical key can be pulled out of the mechanical key hole to open or lock the door. The sliding cover is buckled on the front shell and slides up and down through the sliding groove on the front shell. When the sliding cover slides to the top, the ECAS function button is blocked to prevent the ECAS system related functions from being accidentally touched and turned on, that is, it can block the key button and greatly reduce the accidental touch rate of the remote control button; when the sliding cover slides to the bottom, the ECAS function button is exposed, and the related buttons can be operated at this time to achieve the function adjustment related to the ECAS system. The smart key combines the car remote control key and the ECAS remote control into one, so that the overall volume and cost are greatly reduced. In addition, the wired ECAS remote control is changed to a wireless remote control, the operating range is increased, and it is not limited by space. Improve the user experience of ECAS system control.

[0038] The following is a detailed description of the way in which the smart key of the embodiment of the utility model controls the ECAS system function of the vehicle. For example:

[0039] (1) The PEPS system receives the key signal sent by the smart key.

[0040] The smart key is also called the remote control key. The PEPS system includes a PEPS controller. When a button of the remote control key is pressed, the key signal is sent to the PEPS controller via Bluetooth.

[0041] (2) Identify the signal type of the key signal.

[0042] In one embodiment of the present application, identifying the signal type of the key signal includes: obtaining a signal number carried by the key signal; determining the signal type according to the signal number, wherein a plurality of different signal numbers may correspond to the same signal type.

[0043] For example, the signal numbers include 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The meanings of these signal numbers are predefined, such as: 0 is a non-ECAS function key (i.e., a signal sent by a traditional key); 1 is for the front axle, 2 is for the rear axle, 3 is for the lifting axle, 4 is for the front axle and the rear axle, 5 is for the front axle and the lifting axle, 6 is for the rear axle and the lifting axle, and 7 is for the front axle, the rear axle, and the lifting axle.

[0044] In this way, the signal type can be determined according to the signal number, for example, if the signal number is 0, it means it is a signal type of a traditional key signal, and if it is any one of 1-9, it means it is a signal type for controlling the ECAS system. In other words, the PEPS controller can determine whether the key signal is an ECAS controller signal according to the signal number.

[0045] (3) When the signal type is an ECAS system control signal, the key signal is sent to the ECAS system, so that the ECAS system controls the air suspension of the vehicle according to the key signal.

[0046] That is to say, when the PEPS controller determines that the key signal is an ECAS controller signal, it sends the key signal to the ECAS system, so that the ECAS system controls the vehicle's air suspension action according to the key signal, such as the ECAS controller selects different bridges for lifting and lowering control according to the received key signal.

[0047] In a specific example, the key signal is sent to the ECAS system so that the ECAS system controls the air suspension action of the vehicle according to the key signal, including: sending the key signal to the ECAS system via a CAN message at a predetermined time period, so that the ECAS system determines the target bridge to be adjusted in the air suspension according to the signal number, and determines the adjustment action of the target bridge according to the key value corresponding to the key signal, so as to control the target bridge to rise or fall according to the adjustment action.

[0048] In this example, before sending the key signal to the ECAS system, the process also includes: obtaining the running state of the vehicle; determining whether an air suspension adjustment condition is met according to the running state of the vehicle; and prohibiting sending the key signal to the ECAS system if the air suspension adjustment condition is not met.

[0049] Specifically, if Figure 1 As shown, combined with Figure 5 When the remote control key is used to select a mode, the remote control key can record the currently selected mode and flash the indicator light according to the selected mode, but generally, it will not immediately send a signal to the PEPS controller via Bluetooth, thereby reducing communication power consumption as much as possible. Of course, after selecting a mode, such as selecting the front axle mode, it means that the height of the front axle needs to be adjusted. At this time, when the key signal for controlling the lifting is triggered, the remote control key immediately sends a key signal to the PEPS controller.

[0050] In the above description, the ECAS modes of the remote control key include the following: front axle, rear axle, lifting axle, front axle and rear axle, front axle and lifting axle, rear axle and lifting axle, front axle, rear axle and lifting axle.

[0051] In order to improve the service life of the remote control key, after the remote control key triggers an ECAS function key, it can be released immediately without continuously pressing the key. After the PEPS controller receives the ECAS key signal, it sends it to the ECAS controller via a CAN message, for example, at a cycle of 10ms.

[0052] In order to reduce the CAN bus load rate between the PEPS controller and the ECAS controller, the PEPS controller will determine whether the conditions for controlling the ECAS controller to lift the axle are met. For example, if the vehicle is running and the lift axle is not running, the PEPS controller will not send a CAN message to the ECAS controller even if it receives the ECAS function button sent by the remote control key. In this way, the CAN bus load rate between the PEPS controller and the ECAS controller is reduced.

[0053] In one embodiment of the present application, the vehicle's smart key also includes: after the ECAS system receives the memory function button sent by the smart key and forwarded by the PEPS system, if the current air suspension position is not recorded, it is recorded, and after receiving the memory function button again, the position of the air suspension is automatically adjusted to the recorded air suspension position.

[0054] Furthermore, it also includes: during the process of adjusting the air suspension, if the position of the air suspension reaches the limit position, the adjustment of the air suspension is automatically stopped, and an alarm message is fed back to the PEPS system so that the PEPS system forwards the alarm message to the smart key to give a prompt through the smart key.

[0055] Specifically, after the user memory button is pressed for a long time with the remote control key, the ECAS controller is responsible for recording the current position information of each bridge. When the user memory button is pressed for a long time with the remote control key, the ECAS controller automatically raises and lowers each bridge to the memory position.

[0056] When the bridge reaches the maximum or minimum height, the ECAS controller controls each bridge to stop automatically and sends an over-limit alarm message to the PEPS controller. The PEPS controller forwards the over-limit alarm message to the remote control key, and the remote control key prompts the user by quickly flashing the ECAS indicator light above.

[0057] According to the smart key of the vehicle in the embodiment of the present application, an ECAS remote control button is integrated on the smart key. When the ECAS function button is triggered, the button signal is sent to the ECAS system in a wireless manner, so that the ECAS system controls the air suspension action of the vehicle. The traditional ECAS remote control is eliminated, and the car remote control key and the ECAS remote control are combined into one, which facilitates the operation of the ECAS function and has the advantage of convenient operation. In addition, the smart key can relatively remotely control the ECAS function of the vehicle through wireless technology, which improves the use distance and regional range of the ECAS function and improves the control experience of the ECAS function.

[0058] In one embodiment, a vehicle is provided, comprising: a smart key for the vehicle according to the above embodiment, wherein the vehicle cancels the traditional ECAS remote control, combines the vehicle remote control key and the ECAS remote control into one, facilitates the operation of the ECAS function, has the advantage of convenient operation, and the smart key can relatively remotely control the ECAS function of the vehicle through wireless technology, thereby improving the use distance and regional range of the ECAS function and improving the control experience of the ECAS function.
