Embodiment
Describe embodiment of the present utility model below in detail, described embodiment's example is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Be exemplary below by the embodiment who is described with reference to the drawings, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
As shown in Figure 1, the starting circuit of Starter of the present utility model comprises starting protection relay J 2, oil pump control relay J 1, ignition switch SW and clutch switch K1, ignition switch SW comprises four gears, be respectively locked shelves (LOCK), part energising shelves (ACC), fully energized shelves (ON), start shelves (START), four gears can only be opened in order, open by the order of LOCK-ACC-ON-START or START-ON-ACC-LOCK, four gear correspondences four different power supply terminals, the first power supply terminal T1 meets car load storage battery B, there is electricity always, when ignition key SW is in LOCK shelves, second, third, the 4th power supply terminal T2, T3, T4 be all without electricity, while being in ACC shelves, second source terminal T2 has electricity, and the 3rd, the 4th power supply terminal T3, T4 are without electricity, while being in ON shelves, second, third power supply terminal T2, T3 have electricity, and the 4th power supply terminal T4 is without electricity, while being in START shelves, the 3rd, the 4th power supply terminal T3, T4 have electricity, and second source terminal T2 is without electricity.For starting circuit of the present utility model, there is the 3rd power supply terminal T3 of electricity to be electrically connected with the operating voltage input end of the electronic control unit (ECU) 1 of motor at ON shelves and START shelves, when being threaded to ON shelves at ignition key, for ECU1 power supply, and then startup ECU1, ignition switch SW has the 4th power supply terminal T4 of electricity to be electrically connected with the start-up request signal input end of ECU1 at START shelves, when being threaded to START shelves at ignition key, to ECU1 output start-up request signal, the coil of oil pump control relay J 1 is connected electrically between the oil pump control signal output part and bonding of ECU1, the coil of starting protection relay J 2 is connected electrically between the startup control signal output terminal and bonding of ECU1, described clutch switch is connected electrically between the clutch signal input part and bonding of described electronic control unit, make ECU1 know the state of clutch.
