[0065] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0066] The embodiment of the present application provides a vehicle controller and a vehicle including the vehicle controller, wherein the vehicle may be a car, a bus, or a truck. For example, the vehicle may be any one of an electric vehicle / electric vehicle (EV), a pure electric vehicle / battery electric vehicle (PEV / BEV), a hybrid electric vehicle (HEV), a range extended electric vehicle (REEV), a plug-in hybrid electric vehicle (PHEV), and a new energy vehicle (NEV).

[0067] The controller can be electrically connected to the battery and motor in the vehicle to distribute the power of the battery so that part of the battery power is used to power the low-voltage electrical equipment in the vehicle and part of the battery power is used to power the drive motor. The vehicle usually also includes devices such as the vehicle controller, gateway controller and air conditioning manager. Currently, the vehicle controller, gateway controller and air conditioning manager are usually installed separately in other parts of the vehicle.

[0068] As described in the above background technology, the above-mentioned devices are arranged in a relatively dispersed manner and have a low degree of integration, which increases the space occupied by the devices in the vehicle and increases the overall cost of the vehicle.

[0069] In order to solve the above problems, an embodiment of the present application provides a vehicle controller, which integrates seven modules including an on-board charger, a DC converter, a power distribution unit, a vehicle controller module, a gateway controller module, an air-conditioning manager module and a motor controller module into the vehicle controller. In this way, the vehicle controller module, the gateway controller module, the air-conditioning manager module and the vehicle controller share a circuit control board and a housing, and there is no need to reserve space for the above modules in other positions of the vehicle. The integration level of each module in the vehicle can be effectively improved, and the compactness of the overall layout of the vehicle can be improved, thereby effectively reducing the space occupied by each module in the vehicle and achieving the effect of reducing weight and cost.

[0070] The vehicle controller provided in the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0071] Figure 1 A schematic diagram of the structure of a vehicle controller provided in an embodiment of the present application is shown in FIG. Figure 2 This is a front view of a vehicle controller provided by an embodiment of the present application with part of the housing removed. Figure 3A schematic diagram of the structure of a vehicle controller provided in an embodiment of the present application with part of the shell removed.

[0072] The vehicle controller 100 provided in the embodiment of the present application is shown in FIG. Figure 1 and Figure 2 As shown, the vehicle controller 100 may include a housing 110 and an on-board charger 120 (OBC), a DC-DC Converter 130 (DC-DC Converter), a power distribution unit 140 (PDU), and a first circuit control board 150 disposed in the housing 110. The first circuit control board 150 may include a vehicle control unit (VCU), a gateway controller (GW), an air conditioning manager, and an intergrated power unit (IPU).

[0073] The onboard charger 120 can be used to charge the battery of the vehicle. For example, the onboard charger 120 can be electrically connected to the battery, and the onboard charger 120 can be electrically connected to an external charging device to charge the battery. The DC converter 130 can be electrically connected to the onboard charger 120, and the DC converter 130 can adjust the voltage of the DC power. For example, it can convert high-voltage DC into low-voltage DC, or it can convert low-voltage DC into high-voltage DC to meet the power demand of the vehicle.

[0074] The power distribution unit 140 can distribute the power of the battery so that the battery can power various electrical devices in the vehicle. The function of the vehicle controller is to collect the accelerator pedal signal, brake pedal signal and other component signals, and after making corresponding judgments, control the actions of the lower-level component controllers to drive the car to run normally.

[0075] The gateway controller module is responsible for coordinating data exchange and fault diagnosis between data networks with different structures and characteristics. For example, it can be used to coordinate information transmission between various modules, and for the data sent by each computer module, it can be given priority according to the importance of the data. The air conditioning manager can control the air conditioning in the vehicle so that the air conditioning can adjust the temperature in the passenger compartment of the vehicle according to user needs to improve the comfort of the user in the vehicle. The motor controller module can control the drive motor of the vehicle. For example, the motor controller module can convert the electric energy stored in the power battery into the electric energy required by the drive motor according to the gear position, throttle, brake and other instructions to control the start-up, forward and backward speed, climbing strength and other driving states of the electric vehicle, or help the electric vehicle brake and store part of the braking energy in the power battery.

[0076] Among them, combined Figure 3 As shown, the housing 110 may include a first housing 111 and a second housing 112, the first housing 111 may have a first cavity 1111, the second housing 112 may have a second cavity 1121, and the on-board charger 120 and the DC converter 130 may be located in the first cavity 1111 of the first housing 111. The power distribution unit 140 and the first circuit controller may be located in the second cavity 1121 of the second housing 112. Furthermore, the first housing 111 and the second housing 112 may be arranged in parallel.

[0077] The embodiment of the present application integrates seven modules, namely, an on-board charger 120, a DC converter 130, a power distribution unit 140, a vehicle controller module, a gateway controller module, an air-conditioning manager module and a motor controller module, into a vehicle controller 100. In this way, the vehicle controller module, the gateway controller module, the air-conditioning manager module and the vehicle controller 100 can share a circuit control board and a housing 110, without the need to reserve space for the above modules in other locations of the vehicle. This can effectively improve the integration of each module in the vehicle and improve the compactness of the overall layout of the vehicle, thereby effectively reducing the space occupied by each module in the vehicle and achieving the effect of reducing weight and cost.

[0078] Moreover, by arranging the first shell 111 and the second shell 112 side by side, the space occupied by the shell 110 in the height direction can be reduced, which can facilitate the arrangement of the motor and the motor in the vehicle and help improve the rationality of the overall layout of the vehicle.

[0079] In an embodiment of the present application, the vehicle controller 100 may also include a second circuit control board (not shown in the figure), the second circuit control board may be located in the first cavity 1111 of the first shell 111, the on-board charger 120 and the DC converter 130 may be located on a second circuit board, and the on-board charger 120 and the DC converter 130 may both be electrically connected to the second circuit control board, and the on-board charger 120 and the DC converter 130 may be electrically connected through the second circuit control board.

[0080] Continue to see Figure 2 and Figure 3 As shown, the vehicle controller 100 may also include an AC charging interface 160, which may be located on the first housing 111. One end of the AC charging interface 160 may be electrically connected to the onboard charger 120, and the other end may be used to be electrically connected to an AC slow charging charger. The onboard charger 120 in the vehicle controller 100 may be electrically connected to an external charger through the AC charging interface 160 to charge the battery. For example, the onboard charger 120 may be electrically connected to the battery of the vehicle, so that the electric energy in the charger may enter the onboard charger 120 through the AC charging interface 160, and then enter the battery from the onboard charger 120 to charge the battery.

[0081] For example, see Figure 2 and Figure 3 As shown, the vehicle controller 100 may also include a battery plug interface 161, which may be located on the second housing 112, one end of the battery plug interface 161 may be electrically connected to the onboard charger 120, and the other end may be electrically connected to the battery of the vehicle. In this way, in the process of charging the battery through AC slow charging, the electric energy in the charger may first enter the onboard charger 120 from the AC charging plug interface 160, and then be transmitted from the onboard charger 120 to the battery plug interface 161, and finally enter the battery from the battery plug interface 161 to realize charging of the battery.

[0082] Continue to see Figure 2 and Figure 3 As shown, the vehicle controller 100 may also include a DC output socket 162, one end of which may be electrically connected to the DC converter 130, and the other end of which may be electrically connected to an electrical device in the vehicle to supply power to the electrical device in the vehicle. For example, the DC output socket 162 may provide low-voltage DC power to low-voltage electrical devices in the vehicle, the DC output socket 162 may be electrically connected to the battery socket 161, the battery may transmit high-voltage DC power to the DC converter 130, and the DC converter 130 may convert the high-voltage DC power into low-voltage DC power to meet the voltage requirements of the electrical devices.

[0083] Continue to see Figure 2 and Figure 3 As shown, the power distribution unit 140 may include a fast charging relay 141, one end of which may be electrically connected to the battery plug interface 161, and the vehicle controller 100 may also include a fast charging plug interface 163, which may be located on the second shell 112, one end of which may be electrically connected to the other end of the fast charging relay 141, and the other end of which may be used to be electrically connected to a fast charging charger.

[0084] For example, the fast charging charger can be a DC fast charging charger. When the vehicle needs to be charged by fast charging, the charging gun of the fast charging charger can be inserted into the fast charging interface 163 to be electrically connected to the fast charging relay 141 in the vehicle control. The electric energy in the fast charging charger can first enter the fast charging relay 141 through the fast charging interface 163, and then be transmitted from the fast charging relay 141 to the battery interface 161, and finally enter the battery from the battery interface 161 to enable fast charging of the battery.

[0085] Continue to see Figure 2 and Figure 3 As shown, the vehicle controller 100 may also include an AC output socket 164, which may be located on the second housing 112, one end of which may be electrically connected to the battery socket 161, and the other end of which may be used to be electrically connected to the battery heater and the air conditioning compressor. In this way, the battery can supply power to the battery heater and the air conditioning compressor, so that the battery heater and the air conditioning compressor can work normally.

[0086] Figure 4 A cross-sectional view of a vehicle controller provided in an embodiment of the present application, Figure 5 A partial view of a vehicle controller provided in an embodiment of the present application.

[0087] Continue to see Figure 4 As shown, the vehicle controller 100 may also include a filter device 170 and an AC-DC converter 130 electrically connected to the filter, the filter device 170 may be electrically connected to the battery plug interface 161, and the DC-AC converter 180 may be used to be electrically connected to the motor of the vehicle. For example, the DC power in the battery may first enter the filter, and the filter may filter the current. Then, the current after filtering by the filter may enter the bus capacitor, and then pass through the DC-AC converter 180, and the DC-AC converter 180 may convert the DC power into AC power to power the motor, so that the motor can rotate under the AC power supply.

[0088] Continue to see Figure 4As shown, the DC-AC converter 180 may be located below the first circuit control board 150, and combined with Figure 5 As shown, the vehicle controller 100 may further include a shielding plate 190, and the shielding plate 190 may be located between the DC-AC converter 180 and the first circuit control board 150. The DC-AC converter 180 is a high-voltage electrical device, and the first circuit control board 150 is a low-voltage electrical device. The shielding plate 190 may isolate the low-voltage area from the high-voltage area, so that the high-voltage and low-voltage areas are divided into zones, which may improve the anti-electromagnetic interference capability of the vehicle controller 100 and help improve the reliability of the vehicle controller 100.

[0089] Figure 6 A schematic diagram of the structure of a filtering device provided in an embodiment of the present application.

[0090] See also Figure 6 As shown, the filter device 170 may include an inner housing 171, a filter 172 and a capacitor 173, and the filter 172 and the capacitor 173 may be integrated in the inner housing 171. One end of the filter 172 may be electrically connected to one end of the capacitor 173, the other end of the filter 172 may be used to be electrically connected to the battery of the vehicle, and the other end of the capacitor 173 may be used to be electrically connected to the motor of the vehicle, and the electric energy in the battery may pass through the filter 172 and the capacitor 173 in sequence to supply power to the motor.

[0091] The filter 172 can filter the electric energy in the battery to remove impurity waves. The capacitor 173 can store the electric energy of the battery and then smoothly input it into the motor to play a role in smoothing the voltage. For example, the capacitor 173 can be a thin film capacitor.

[0092] By integrating the filter 172 and the capacitor 173 in an inner housing 171, the number of inner housings 171 and fixings in the vehicle controller 100 can be reduced, thereby reducing the cost of the vehicle controller 100. Moreover, it is also helpful to improve the integration of the internal components of the vehicle controller 100, and can effectively improve the rationality of the layout of the internal components of the vehicle controller 100, thereby effectively improving the miniaturization design of the vehicle controller 100.

[0093] In the embodiment of the present application, the vehicle controller 100 may further include a filling glue (not shown in the figure), which may be filled in the inner shell and wrap the filter 172 and the capacitor 173, for example, see Figure 3As shown, the inner housing 171 may have a housing cavity 1711, and a filling glue may be filled in the housing cavity 1711. For example, the filling glue may be an epoxy glue, and the filling glue may fix the filter 172 and the capacitor 173 to reduce or avoid the filter 172 and the capacitor 173 from moving in the inner housing 171, which is beneficial to improving the reliability and stability of the filter 172 and the capacitor 173 in the inner housing 171.

[0094] Moreover, the filling glue can also play an insulating and heat-conducting role, which can prevent the components in the inner shell 171 from short-circuiting, and also help to dissipate heat and cool the filter 172 and the capacitor 173.

The electrical energy in the battery may be transmitted to the filter device 170 through the battery connector 1611, and then transmitted to the motor through the filter device 170 to power the motor.

[0097] The battery connector 1611 and the filter device 170 can be electrically connected by screw connection. For example, the battery connector 1611 and the filter can be fastened by bolt fasteners to achieve circuit conduction between the battery connector 1611 and the filter. By electrically connecting the battery connector 1611 and the filter device 170 by screw connection, the bolt connection structure is simple and low in cost, which can effectively reduce the cost of the vehicle controller 100. Moreover, there is no need to set a plug-in seat on the housing 110, which can effectively reduce the overall size of the vehicle controller 100 and improve the miniaturization design of the vehicle controller 100.

[0098] Moreover, the bolt fasteners are firmly and reliably connected, which can effectively improve the firmness and reliability of the connection between the battery connector 1611 and the vehicle controller 100 .

The electric energy in the fast charging charger can be transmitted to the fast charging relay 141 through the fast charging connector 1631, and then transmitted to the battery through the fast charging relay 141 to charge the battery.

[0100] The fast charging connector 1631 and the fast charging relay 141 can be electrically connected by screw connection. Correspondingly, the fast charging connector 1631 and the fast charging relay 141 can be fastened by bolt fasteners to achieve circuit conduction between the fast charging connector 1631 and the fast charging relay 141.

[0101] By electrically connecting the fast charging connector 1631 and the fast charging relay 141 by screw connection, the bolt connection structure is simple and low in cost, which can effectively reduce the cost of the vehicle controller 100. Moreover, there is no need to set a plug-in socket on the housing 110, which can effectively reduce the overall size of the vehicle controller 100 and improve the miniaturization design of the vehicle controller 100.
