[0052] Optionally, as shown in Figure 5 and Figure 6 The controller 2 comprises a fastener; the controller 2 is provided with at least one mounting foot 21; and the fastener passes through the mounting foot 21 and is adapted to be connected to the first cover plate 3.

[0053] In the embodiment of the present application, at least one mounting foot 21 is arranged on the side of the controller 2 close to the first cover plate 3; and the fastener is connected with the first cover plate 3 through the mounting foot 21. In this way, the controller 2 is stably connected on the first cover plate 3 through the mounting foot 21, so as to ensure the stable operation of the controller 2.

[0054] In some embodiments, as shown in Figure 5 and Figure 6 , two mounting feet 21 can be arranged on both sides of the controller 2. In this way, the connection strength between the controller 2 and the first cover plate 3 can be ensured.

[0057] Optionally, the present application provides a suspension system, which comprises the controller in the above-mentioned embodiments.

[0058] In the embodiment of the present application, the controller 2 is arranged in the mounting cavity formed by the front wall 1, the first cover plate 3 and the second cover plate 4, and is detachably connected to the first cover plate 3. In this way, on the one hand, the controller 2 is installed in the space in the mounting cavity, so as to avoid occupying the space of the axle, which is beneficial to the arrangement of other structures on the axle; on the other hand, the controller 2 can be protected by the first cover plate 3 and the second cover plate 4, so as to avoid the problem that the controller 2 is damaged due to no protection when arranged on the axle.

[0059] Optionally, as shown in Figure 1 and Figure 2 , the present application further comprises a low-voltage wire harness 7; one end of the low-voltage wire harness is electrically connected with the controller 2, and the other end of the low-voltage wire harness 7 is adapted to be electrically connected with the vehicle master controller.

[0079] Optionally, as shown in Figure 7 , the high-voltage wire harness and the electromagnetic damping suspension are further included; at least part of the high-voltage wire harness is arranged in the mounting cavity; one end of the high-voltage wire harness is electrically connected with the controller 2, and the other end of the high-voltage wire harness is electrically connected with the electromagnetic damping suspension.

[0083] It should be noted that the electromagnetic damping suspension suppresses vibration in milliseconds through electromagnetic reaction to realize the stability and comfort of the vehicle. The electromagnetic damping suspension controls the up-down movement of the wheel by using the attractive force and repulsive force of the magnet to realize fast response and stable damping performance. Compared with the ordinary suspension, the electromagnetic damping suspension can make the vehicle run more stably on the rough road.

[0084] In the embodiment of the application, the number of high-voltage wire harnesses is at least two, the number of electromagnetic damping suspensions is at least two, the high-voltage wire harnesses correspond to the electromagnetic damping suspensions one by one; each electromagnetic damping suspension corresponds to at least one wheel; one end of the high-voltage wire harness is electrically connected with the controller, and the other end of the high-voltage wire harness is electrically connected with the corresponding electromagnetic damping suspension. In this way, one controller 2 can control the operation of at least two electromagnetic damping suspensions through at least two high-voltage wire harnesses respectively.

[0085] Exemplarily, when the number of high-voltage wire harnesses is two and the number of electromagnetic damping suspensions is two; the two high-voltage wire harnesses include a first high-voltage wire harness 14 and a second high-voltage wire harness 15, and the two electromagnetic damping suspensions include a first electromagnetic damping suspension 16 and a second electromagnetic damping suspension 17; the first electromagnetic damping suspension 16 corresponds to one wheel, and the second electromagnetic damping suspension 17 corresponds to another wheel; one end of the first high-voltage wire harness 14 is electrically connected to the controller 2, and the other end of the first high-voltage wire harness 14 is electrically connected to the first electromagnetic damping suspension 16; one end of the second high-voltage wire harness 15 is electrically connected to the controller 2, and the other end of the second high-voltage wire harness 15 is electrically connected to the second electromagnetic damping suspension 17.

[0086] It should be noted that the number of high-voltage wire harnesses can also be set to three, four, etc., and the number of electromagnetic damping suspensions can also be set to three, four, etc., which are not limited in the embodiments of the present application.
