Specific embodiment

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, is easy to be well understood to This utility model, but they do not constitute restriction to this utility model.

As shown in figure 1, Vehicle Controller power supply of the present utility model includes input power, filter circuit, metal-oxide-semiconductor, is used for The system base chip of local wake-up and Remote Wake Up, single-chip microcomputer and external power source module, described input power connects filtered electrical The input on road, the outfan of filter circuit connects the input of metal-oxide-semiconductor and the supply voltage end of system base chip, institute respectively The outfan stating metal-oxide-semiconductor connects the power end of external power source module, and the wake-up input of described system base chip connects wake-up Source, the power output end of system base chip connects the power end of single-chip microcomputer, and the control end of system base chip connects single-chip microcomputer The first control end, single-chip microcomputer second control end connect metal-oxide-semiconductor control end.

The basic structure of most system base chip SBC is similar to, and the model of this utility model system base chip is adopted With TLE8262, as shown in Fig. 2 being the internal module schematic diagram of TLE8262.TLE8262 include 3 separate can be independent The 5V power supply (corresponding to VCC1, VCC2, VCC3 in Fig. 3) controlling, 1 CAN module with arousal function, at least one band wake up The LIN module of function, at least one local wake module, interrupt module, Power Supply Monitoring reset and house dog, SPI module and state Machine.Send order by spi bus, state machine receives, configuration power module, CAN module and LIN module.Interrupt module is permissible The abnormality of detection unit, generates interrupt signal.Interrupt source not only includes CAN/LIN message Remote Wake Up, locally calls out Wake up and periodic wakeup, also include CAN/LIN communication mistake, SPI error in data, and each power module excess temperature, under-voltage, The abnormalities such as excessively stream.

The concrete connected mode of TLE8262 is：The local of TLE8262 wakes up input foot and connects local wake source, The CAN of TLE8262 wakes up input and connects CAN message wake source, and the LIN of TLE8262 wakes up input and connects the wake-up of LIN message Source, the supply voltage end of TLE8262 connects input power, and three power output ends of TLE8262 connect the three of single-chip microcomputer respectively Individual power input, TLE8262 bus marco end connects the first control end of single-chip microcomputer.
