Fig. 2 is the signal of the hybrid power entire car controller among 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 set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
The invention provides a kind of signal and power circuit of the entire car controller that can switch, can realize that under improper situation power supply switches, 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 entire car controller and power supply switch circuit; Engine control module) and HCU supply module 5 (HCU: Multi-energy Powertrain Controller) comprise the digital control analog switch module of watchdog circuit module 1, anti-phase Schmidt trigger 2, two passages 3, ECM supply module 4 (ECM:; (MCU: feeding-dog signal output microcontroller) is connected the input of this watchdog circuit module 1 with MCU; The output of this watchdog circuit module 1 is connected with the input of this anti-phase Schmidt trigger 2 and HCU supply module 5 respectively, and the output of this anti-phase Schmidt trigger 2 is connected with the input of digital control analog switch module 3 of this two passage and ECM supply module 4 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 one the tunnel is the HCU power supply signal, and one the tunnel is the ECM power supply signal.When the MCU operate as normal, feeding-dog signal access door dog circuit module 1 is arranged, send digital signal " 1 ".Digital signal " 1 " gets into the Enable Pin of HCU supply module 5, and starts HCU supply module 5 and let its work.Simultaneously, digital signal " 1 " gets into anti-phase Schmidt trigger 2 and obtains digital signal " 0 " through operated in anti-phase.This signal gets into the Digital Signals end in the digital control analog switch module 3 of two passages, control output HCU power supply signal.The Enable Pin that digital signal " 0 " gets into ECM supply module 4 is not equally worked it.So just realized the HCU power supply.Undesired when MCU work, when not having feeding-dog signal access door dog circuit module 1, send digital signal " 0 ".Digital signal " 0 " gets into the Enable Pin of HCU supply module 5, and it is not worked.Simultaneously, digital signal " 0 " gets into anti-phase Schmidt trigger 2 and obtains digital signal " 1 " through operated in anti-phase.This signal gets into the Digital Signals end in the digital control analog switch module 3 of two passages, control output ECM power supply signal.Digital signal " 1 " gets into the Enable Pin of ECM supply module 4, makes its work.So just realized the ECM power supply.
The signal of this hybrid power entire car controller and power supply switch circuit are provided with the switch mode of power supply; When one tunnel power-fail, can switch to other one road power supply immediately and supply power, and can show the source of current power supply circuits intuitively; Having improved the hybrid power entire car controller greatly gets stable; Can realize that under improper situation power supply switches, thus can be stable power supply is provided, avoid power-fail to cause systemic breakdown.
The signal of this hybrid power entire car controller of the present invention and power supply switch circuit have been integrated multiple different signal sources, and be 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, under the situation that system allows, the present invention can expand to external more function module simultaneously, thereby expands its function to greatest extent.
The above is merely embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within 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.
