Power supply system, in-vehicle connector, peripheral device, power supply method, and vehicle

technical field

The invention relates to the field of vehicle-mounted connectors, in particular to a power supply system, a vehicle-mounted connector, peripheral equipment, a power supply method and a vehicle.

Background technique

With the development of the vehicle industry, there are more and more types of peripheral devices connected to the vehicle. Generally speaking, the vehicle will transmit data with the peripheral device or supply power to the peripheral device through various interfaces on the vehicle. The data that the vehicle interacts with peripheral devices can be divided into vehicle speed, mileage, braking, engine speed, steering wheel angle, temperature of each component, engine torque, accelerator opening, brake pedal, gear lever position, etc. collected from the CAN network CAN network data, as well as map data, positioning data, control command data for playing music, playing video, audio input, etc., the collected image and voice data of the driver, the switch control data of each device associated with the HMI system, each Device parameter setting data, music file and video file data, etc. HMI system data collected from the HMI system or stored in the HMI system.

In the prior art, the vehicle can supply power to peripheral devices through an extension socket installed at the cigarette lighter or a USB power supply interface on the body; the peripheral devices can receive HMI system data through a data interface connected to the HMI system; The OBD interface on the vehicle receives CAN network data.

However, the functions of the above interfaces are relatively independent. For example, the USB interface generally only has the function of power supply, and cannot receive HMI system data and CAN network data; and the interface connected to the HMI system cannot receive CAN network data; the interface connected to the CAN network And can not receive HMI system data. This limits the development of peripheral devices.

In addition, the OBD interface is a diagnostic interface, and the information obtained is CAN network data. This interface is a safety interface. If it encounters illegal data writing by peripheral devices, this in turn will affect the safety of the vehicle itself through the OBD interface, and there are potential safety hazards. .

Vehicle manufacturers generally place the OBD interface in a relatively hidden location, such as below the fuse box, below the storage box, and below the center console. After the peripheral device is connected to the OBD interface, it will have the disadvantage that the wiring line is complicated or the peripheral device cannot be laid out.

In addition, in the prior art, power is supplied to peripheral devices through the USB interface on the vehicle. However, as the number of peripheral devices increases, the voltage required by the peripheral devices is also different, and one USB interface can no longer meet the requirements of many peripheral devices. For the power supply needs of each peripheral device, the existing vehicles will be configured with USB interfaces that provide different voltages, but there are more and more types of peripheral devices, so that this method cannot meet the voltage requirements of more peripheral devices. , and configuring additional adapters will be more cumbersome, which limits the development of peripheral devices.
