Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

Fig. 1 is a block diagram of a body area controller provided according to one embodiment of the present disclosure. As shown in fig. 1, the body area controller 100 may be integrated with a secure network controller 101, an ethernet switching module 102, an MCU chip 103, a CAN bus module 104, and a body control module 105.

The MCU (Microcontroller Unit) chip 103 is connected to the ethernet exchange module 102, the CAN bus module 104, and the body control module 105, respectively. The secure network controller 101 includes an SOC chip 1011, and the SOC chip 1011 is connected to the MCU chip 103 via the ethernet switch module 102, so as to realize bidirectional communication between the secure network controller 101 and the MCU chip 103. The MCU chip 103 is configured to control at least one device of the body area controller 100 to power down when the entire vehicle meets a preset condition, so that the entire vehicle is in a low power consumption state.

The secure network controller 101 is configured to implement a cloud interaction function, and support 4G, 5G, and the like. The SOC chip 1011 in the secure network controller 101 may be provided with an SOC storage unit for storing data related to the SOC chip 1011, wherein the SOC storage unit may be an emmc (embedded Multi Media card). The ethernet switching module 102 is used to implement an ethernet switching function. The CAN bus module 104 is configured to record messages on the multiple CAN buses, so as to store the messages in the MCU chip 103 or transmit the messages to the cloud through the secure network controller 101. Illustratively, the MCU chip 103 may be provided with an MCU storage unit for storing data transmitted by the CAN bus module 104, wherein the MCU storage unit may be an eMMC. The body control module 105 may be a BCM for controlling the body, such as controlling the vehicle lights, doors, etc., and for collecting vehicle data via sensors, which may include, but are not limited to, light sensors, temperature sensors, etc.

The MCU chip 103 determines that the entire vehicle needs to be adjusted to a low power consumption state by identifying whether the entire vehicle meets a preset condition, i.e., determines how to switch the entire vehicle between the low power consumption state and a normal operating state (i.e., an awake state). The preset conditions are used for judging whether the whole vehicle can be in a low power consumption state or not, and can be set according to actual demand adaptability. Therefore, the MCU chip 103 can control at least one device of the body area controller 100 to be powered off when the entire vehicle meets the preset conditions, so that the entire vehicle is in a low power consumption state.

Optionally, the SOC chip 1011 is configured to determine whether the entire vehicle meets a preset condition, and send a first notification signal to the MCU chip 103 to trigger the MCU chip 103 to control at least one device of the vehicle body area controller 100 to power down when the entire vehicle meets the preset condition. That is to say, the SOC chip 1011 determines whether the entire vehicle meets the predetermined condition, and the SOC chip 1011 synchronizes the determination result to the MCU chip 103 through the first notification signal, so as to assist the MCU chip 103 to control the entire vehicle to enter the low power consumption state.

Alternatively, the SOC chip 1011 may be connected with a plurality of peripheral devices. Wherein, the peripheral device may include at least one wireless network module. Fig. 2 shows a schematic diagram of a body area controller provided by another embodiment of the present disclosure. As shown in fig. 2, only a schematic structural diagram of the peripheral device including 1 wireless network module is shown, and for a case that the peripheral device includes two or more wireless network modules, a connection manner of each wireless network module may refer to a connection manner of the wireless network module in this drawing. As can be seen from fig. 2, each wireless network module is used to assist the SOC chip 1011 in network data transmission. Accordingly, the SOC chip 1011 may place the target peripheral device in a reset state when the entire vehicle meets the preset condition, and then transmit the first notification signal to the MCU chip 103. The target peripheral component is a peripheral component of the SOC chip 1011 except for the wireless network module.

That is, when the entire vehicle meets the preset condition, the SOC chip 1011 resets all the other components except the wireless network module in the external components thereof, so as to power down the vehicle. And after success, a first notification signal is sent to the MCU chip 103 to notify the MCU chip 103 that the above-mentioned peripheral components have been powered down.

After that, the MCU chip 103 sets the peripheral devices of the MCU chip 103 in a reset state when receiving the first notification signal and the entire vehicle is not woken up, and then sends a first feedback signal to the SOC chip 1011 to notify the SOC chip 1011 of the situation.

The MCU chip 103 may be connected to an SBC (System base Chips) chip, where the SBC chip is configured to receive a wake-up event, and the wake-up event is configured to wake up the entire vehicle from a low power consumption state. Therefore, the MCU chip 103 can determine whether the whole vehicle is woken up by determining whether the SBC chip receives a wake-up event. If the SBC chip receives the wake-up event, the whole vehicle is determined to be awakened, and if the SBC chip does not receive the wake-up event, the whole vehicle is determined not to be awakened.

The SOC chip 1011 stores identification information of at least one wireless network module that should be kept in a sleep state when the entire vehicle is in a low power consumption state. In general, when the entire vehicle is in a low power consumption state, all wireless network modules are not powered off in consideration of the remote wake-up function of the entire vehicle, but one or more of the wireless network modules are kept in a sleep state to meet the remote wake-up requirement. Wherein, which one or more of the wireless network modules is/are not powered off is reserved, and the setting can be performed in advance according to the actual requirement.

Therefore, after receiving the first feedback signal, the SOC chip 1011 may further put the target wireless network module indicated by the identification information into a sleep state, shut down other wireless network modules except the target wireless network module, and then send a second notification signal to the MCU chip 103. Meanwhile, after the SOC chip 1011 sends the second notification signal, the current chip parameters of the SOC chip 1011 are saved, and a third notification signal is sent to the MCU chip 103.

Optionally, the body area controller 100 may further include a first power supply for supplying power to the wireless network module and a second power supply for supplying power to the SOC chip 1011. The plurality of wireless network modules can be respectively supplied with power through the plurality of first power supplies.

The MCU chip 103 may also turn off the first power corresponding to the target wireless network module when receiving the second notification signal and the entire vehicle is not awakened, thereby implementing power-down of part of the first power.

The MCU chip 103 may further put the SOC chip 1011 to a reset state and turn off the second power supply when receiving the third notification signal and the entire vehicle is not woken up, thereby powering off the second power supply.

Optionally, after the second power supply is turned off, the MCU chip 103 may also store current chip parameters of the MCU chip 103, and power down the MCU chip 103, so that the entire vehicle is in a low power consumption state.

In addition, if the MCU chip 103 determines that the wake-up event is received through the SBC chip in the process of controlling the entire vehicle to enter the low power consumption state, it indicates that the entire vehicle needs to be woken up at present, and the entire vehicle should not continue to enter the low power consumption state. At this time, the MCU chip 103 may sequentially control the powered-off devices to be powered on according to a preset power-on sequence, so as to stop the entire vehicle entering a low power consumption state.

Meanwhile, the body area controller 100 is further provided with a third power supply for supplying power to the MCU chip 103, so that the MCU chip 103 can turn off its own power supply and turn off the third power supply.

Optionally, the body area controller 100 may also be provided with a fourth power supply for powering the necessary boundary-hold functions. Illustratively, the boundary keeping function power supply during the low power consumption of the whole vehicle can be realized through a fourth power supply with 3.3V constant power. Meanwhile, the RTC (Real _ Time Clock) may be powered by the normal power of the SBC chip.

Alternatively, the SOC chip 1011 may be provided with an SPI (Serial Peripheral Interface) Interface. Correspondingly, the secure network controller 101 may further include a preset encryption chip, the SOC chip 1011 is connected to the preset encryption chip through the SPI interface, the preset encryption chip stores a secret key, and the preset encryption chip is configured to encrypt information transmitted from the SOC chip 1011 by the secret key and decrypt information received by the SOC chip 1011. This can realize the security of communication by the secure network controller 101.

Optionally, the ethernet switching module 102 may include an ethernet switching chip, an ethernet PHY chip, and at least one network port, where the ethernet switching chip is connected to the MCU chip, the SOC chip 1011, and the ethernet PHY chip is connected to the at least one network port.

The positioning module is used for transmitting high-precision positioning information. The remote control console is used for remotely controlling the vehicle at the background. Illustratively, the SOC chip 1011 may be connected with the network video streaming module through an ethernet PHY chip.
