The signal controller may also be a whole vehicle controller for receiving driving information of the vehicle, such as a vehicle speed, an engine speed, etc. The signal controller can also be a controller integrating the suspension controller and the whole vehicle controller, and belongs to the protection scope of the disclosure. The motor controller 3 is provided with a low-voltage interface 304, the low-voltage interface 304 is used for being connected with a signal controller, the low-voltage interface 304 is used as a controller signal interface circuit, a motor control circuit and a driving circuit are arranged inside the motor controller 3, direct current provided by a high-voltage power supply can be converted into alternating current of a suspension motor or other motors through the control circuit according to the requirements sent by the signal controller, and the suspension motor and other motors are driven to work according to the requirements.
In one embodiment of the present disclosure, the suspension system includes a first signal controller located at the front of the vehicle body and a second signal controller located at the rear of the vehicle body, and a low-pressure interface 304 is provided on the first motor controller 31 for connection with the first signal controller. In this way, the low voltage wiring harness of the motor controller to which the first suspension motor 21 and the second suspension motor 22 are connected can be shared, simplifying the low voltage control circuit. Likewise, the second motor controller 32 is provided with a low voltage interface for connection to a second signal controller. The signal controller can send the received signal to the motor controller, and meanwhile receives the related information of the suspension motor fed back by the motor controller, so that the suspension motor is better controlled, and the damping force of the suspension system is better adjusted.
In the present disclosure, as shown in fig. 3, a reserved port 305 is provided on the first motor controller 31, and the reserved port 305 is connected with the input port 301 to selectively input or output a direct current voltage. The reserved port 305 is connected with the input port 301 inside the motor controller 3, when the arrangement space of the high-voltage wire outside the input port 301 is limited, the reserved port 305 can be used as a standby input port to be connected with a high-voltage power supply, and of course, the reserved port 305 can also be used as a direct-current output port to supply power to other high-voltage devices, and here, as shown in fig. 4, the reserved port 305 can be connected with the air-conditioning compressor 4 to supply power to the air-conditioning compressor, so that the air-conditioning compressor 4 does not need to be connected to the battery pack 6 to take power, the circuit arrangement is saved, and the circuit arrangement is simpler.
As shown in fig. 4, the high-voltage power supply takes a battery pack 6 as an example, and the front end and the rear end of the battery pack 6 are respectively provided with a direct current interface through which power can be supplied to an external high-voltage device. The suspension system provided by the present disclosure includes a front suspension and a rear suspension, and the front suspension and/or the rear suspension may be equipped with a driving motor and a driving motor controller 5 according to a vehicle type, and in an embodiment without the driving motor and the driving motor controller 5, as shown in fig. 1, the motor controller 3 is directly connected with the battery pack 6, that is, the input port 301 is directly connected with the output port of the battery pack 6. In the embodiment in which the drive motor and the drive motor controller 5 are mounted, as shown in fig. 3, the input port 301 of the first motor controller 31 is connected to the output port of the battery pack 6 through the drive motor controller 5, taking the previous suspension as an example. The drive motor controller 5 is provided with a dc output port to which the input port 301 of the first motor controller 31 is connected by a high voltage line. The direct current of the battery pack 6 is supplied to the driving motor controller 5 while being branched and supplied to the first motor controller 31 via the driving motor controller 5.

In this embodiment, the front compartment is also provided with an air conditioning compressor 4, which also requires a battery pack 6 to supply direct current. The reserved port 305 of the first motor controller 31 may be connected to the air conditioner compressor 4, and may supply the dc power to the air conditioner compressor 4 in a split manner. Of course, the driving motor controller 5 may be provided with a power supply port for connection with the air conditioner compressor 4, so that the air conditioner compressor 4 may also take power from the driving motor controller 5. The rear suspension power distribution scheme is similar to that of the front suspension, and when the rear axle is provided with the driving motor and the driving motor controller 5, the second motor controller 32 takes power from the driving motor controller 5 of the rear suspension, and when the driving motor is not provided, the second motor controller takes power from the rear end of the battery pack 6. The second motor controller 32 reserves the port 305, and if the input port 301 is not convenient for external connection of the dc harness, the reserved port 305 can be used as a dc input port. Because the boundaries of the vehicle types are different, the reservation mode can improve the adaptability of the second motor controller 32, has more wiring harness arrangement modes and can be selected according to the needs.
The above-mentioned interfaces can be adjusted and arranged according to the need, and in the present disclosure, the first output port 302 and the second output port 303 are arranged opposite to each other, so as to be connected to the first suspension motor 21 and the second suspension motor 22 on both sides, and the input port 301 and the reserved port 305 are arranged on two adjacent sides of the first motor controller 31, so as to be connected inside the first motor controller 31.

In the present disclosure, as shown in fig. 3, a cooling flow passage is provided in the motor controller 3, and both ends of the cooling flow passage are formed with a cooling medium inlet 306 and a cooling medium outlet 307, respectively. Here, the cooling medium may be a cooling liquid or a cooling gas, which falls within the protection scope of the present disclosure. The motor controller 3 is connected into the whole vehicle cooling loop to cool the whole vehicle, so that the motor controller 3 is ensured to work normally, and meanwhile, a high-voltage wire harness and a cooling pipeline are not required to be connected between the motor controllers, so that the whole vehicle power distribution system and the cooling system are greatly simplified.
