Fig. 1 is the functional module connection diagram of signal and the power supply switch circuit of hybrid power whole vehicle controller of the present invention;
Fig. 2 is the signal of the hybrid power whole vehicle controller in Fig. 1 and the circuit diagram of power supply switch circuit.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
The invention provides a kind of signal and power circuit of the entire car controller that can switch, under abnormal condition, can realize electrical source exchange, thus can be stable power supply is provided, avoid power-fail to cause systemic breakdown.
As shown in Figure 1, a kind of signal of hybrid power whole vehicle controller and power supply switch circuit, comprise watchdog circuit module 1, anti-phase Schmidt trigger 2, the digital control analog switch module 3 of two passages, ECM supply module 4(ECM: engine control module) and HCU supply module 5(HCU: Multi-energy Powertrain Controller), the input of this watchdog circuit module 1 and MCU(MCU: microcontroller) feeding-dog signal output be connected, the output of this watchdog circuit module 1 is connected with the input of HCU supply module 5 with this anti-phase Schmidt trigger 2 respectively, the output of this anti-phase Schmidt trigger 2 is connected with the input of ECM supply module 4 with the digital control analog switch module 3 of this two passage respectively.
The digital control analog switch module 3 of this two passage comprises a HCU power supply signal input and an ECM power supply signal input.
Concrete operation principle is:
The digital control analog switch module 3 of two passages has the input of two-way analog signal, and a road is HCU power supply signal, and a road is ECM power supply signal.When MCU normally works, there is feeding-dog signal to enter a dog circuit module 1, send digital signal " 1 ".Digital signal " 1 " enters the Enable Pin of HCU supply module 5, and starts HCU supply module 5 and allow its work.Meanwhile, digital signal " 1 " enters anti-phase Schmidt trigger 2 and obtains digital signal " 0 " through operated in anti-phase.This signal enters the Digital Signals end in the digital control analog switch module 3 of two passages, controls output HCU power supply signal.The Enable Pin that digital signal " 0 " enters ECM supply module 4 equally, does not work it.So just realize HCU power supply.Undesired when MCU work, while not having feeding-dog signal to enter a dog circuit module 1, send digital signal " 0 ".The Enable Pin that digital signal " 0 " enters HCU supply module 5, does not work it.Meanwhile, digital signal " 0 " enters anti-phase Schmidt trigger 2 and obtains digital signal " 1 " through operated in anti-phase.This signal enters the Digital Signals end in the digital control analog switch module 3 of two passages, controls output ECM power supply signal.The Enable Pin that digital signal " 1 " enters ECM supply module 4, makes its work.So just realize ECM power supply.
The signal of this hybrid power whole vehicle controller and power supply switch circuit are provided with the switch mode of power supply, when Dang Yi road power-fail, can be switched to immediately an other road power supply powers, and can show intuitively the source of current power supply circuits, greatly improve hybrid power whole vehicle controller and obtained stability, under abnormal condition, can realize electrical source exchange, thus can be stable power supply is provided, avoid power-fail to cause systemic breakdown.
The signal of this hybrid power whole vehicle controller of the present invention and power supply switch circuit have been integrated multiple different signal source, simple to operate, can measure multiple signals simultaneously, and the feedback of signal is simple and easy to see.
Below only with an execution mode, mentality of designing of the present invention is described, in the situation that system allows, the present invention can expand to external more functional module simultaneously, thereby expands to greatest extent its function.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range that claims were limited.
