Detailed description of the invention
This utility model is based on the motor vehicle driven by mixed power high-voltage interlocking loop (HVIL) of security strategy, sent the low voltage signal of a 12V by Sources controlling device HCU, with high-voltage cable, flow through all of high voltage parts, returning again to Sources controlling device, this is formed for one " loop ".The controller HCU moment monitors the state of this 12V signal circuit, if this loop is broken, then HCU attends school less than the 12V signal returned, and this is it is possible to be the high voltage bus state that occurs in that "off", and this is unsafe condition.HCU and other high-tension electricity parts must take responsive measures at once, by the two methods of hardware and software, by electricity under high-tension system, and bled off by the remaining capacity on bus as early as possible.Whole high-tension system is made to quickly enter safe condition.
In all high-tension systems, high-tension battery bag is high-tension electricity source, is also the place being easiest to out danger, therefore, high-tension battery bag and HCU independently forms a loop, and this cries " PrimaryHVILLoop ", basic high-voltage interlocking loop.Remaining high-voltage electrical systems and parts and HCU are formed a loop again, is referred to as " SecondaryHVILLoop ", secondary high pressure interlocking loop.HCU simultaneously monitors this 2 high-voltage interlocking loops, if there is " open circuit " in any one, and will forbidden energy high-tension system.
Battery management system BMS also must possess the function in oneself's detection HVIL high-voltage interlocking loop, and can force to disconnect high-tension battery bag main contactor by hardware mechanisms.That is, when " basic high-voltage interlocking loop " disconnects, even if HCU does not have any action, BMS also is able to respond voluntarily, disconnect the connection of high-tension battery bag and high-tension electricity bus, bleed off the remaining capacity on high-tension electricity bus, make high-tension system enter benign state.
HCU monitors the specific strategy in HVIL high-voltage interlocking loop:
1) after HCU powers on, 12V power supply status is first determined whether, because stable 12V power supply just can ensure that is sent a normal 12V power supply signal to HVIL high-voltage interlocking loop by HCU.
2), after 12V power good, HCU to judge whether " basic high-voltage interlocking loop " is interrupted.If " basic high-voltage interlocking loop " interrupts, it is simply that non-secure states, such HCU must refrain from sending high-tension electricity " connection " instruction to battery management system BMS and powers on to high voltage bus.If battery management system BMS is " connection " state, HCU needs to send "off" instruction, disconnects high-tension electricity.Meanwhile, HCU is internal arranges " basic high-voltage interlocking loop " malfunction, and car load pattern is forced into " traditional power pattern ".All high-voltage electrical systems are all disabled.
3) HCU also to judge whether " secondary high pressure interlocking loop " is interrupted simultaneously, if " secondary high pressure interlocking loop " interrupts, also being non-secure states, HCU also must refrain from sending high-tension electricity " connection " instruction to battery management system BMS and powers on to high voltage bus.If battery management system BMS is " connection " state, HCU needs to send "off" instruction, disconnects high-tension electricity.Meanwhile, HCU is internal arranges " secondary high pressure interlocking loop " malfunction, and car load pattern is forced into " traditional power pattern ".All high-voltage electrical systems are all disabled.
