Technical field
The invention belongs to technical field of automobile engine, specially refer to a kind of control circuit and controlling method thereof of automobile starter starting protection.
Background technique
Motor must be driven by starter motor, to realize startup.In engine starting process, the transient current in starter motor loop is very large, therefore generally in this loop safety fuse cutout is not set.Starter motor continues starting time long or frequent starting all can make the starter motor overload, causes the heating of starter motor and circuit bundle, and starter motor is ablated, even can cause that car load ablates.If frequent starting simultaneously continuously, storage battery can continuous deep discharges, cause service lifetime of accumulator to shorten even damage.So starter motor is carried out starting protection control, can effectively reduce the starter motor fault, increase service lifetime of accumulator, reduce the vehicle circuitry potential safety hazard.
Summary of the invention
The objective of the invention is to propose a kind of control circuit and controlling method thereof of automobile starter starting protection, starter motor is carried out starting protection control, can effectively reduce the starter motor fault, increase service lifetime of accumulator, reduce the vehicle circuitry potential safety hazard.
The control circuit of automobile starter starting protection of the present invention comprises the car accumulator of successively series connection, output loop and the starter motor of relay, key is that this control circuit also comprises a control unit and an enable switch, described control unit has control signal input end and control signal output terminal, can realize break-make under the control of control unit between described control signal input end and the control signal output terminal; The low tension power supply of the control signal input end of the control loop of described enable switch, relay, control unit and control signal output terminal, automobile is connected successively, to form the low-voltage control circuit of starter motor.
The controlling method of the control circuit of above-mentioned automobile starter starting protection is as follows: described control unit detects the closed situation of enable switch by the voltage that detects the control signal input end; when the closed situation of enable switch does not meet predetermined case; control unit disconnects the connection between control signal input end and the control signal output terminal, with the control of shielding enable switch to starter motor.
Specifically, the described predetermined case that do not meet is that closed frequency surpasses preset frequency, or closed interval exceeds scheduled duration less than predetermined interval or closing time.
Above-mentioned control unit can utilize the single-chip microcomputer stand-alone development, also can with the module integrations such as TCU, ECU, BCM; The parameters such as the closing time of starter motor, closed frequency and closed interval can be set according to the technical requirements of concrete starter motor.
Further, described control unit links to each other with storage battery sensor for detection of battery condition.Described control unit detects battery condition by storage battery sensor, and when the storage battery health status was not good, control unit disconnected the connection between control signal input end and the control signal output terminal, with the control of shielding enable switch to starter motor.
Further, described control unit links to each other with tutorial light or buzzer.When the storage battery health status was not good, control unit was reported to the police by tutorial light or buzzer.
The control circuit cost of automobile starter starting protection of the present invention is low, and control is reliable, and its controlling method can effectively reduce the starter motor fault, increases service lifetime of accumulator, reduces the vehicle circuitry potential safety hazard.
Description of drawings
Fig. 1 is the schematic diagram of the control circuit of automobile starter starting protection of the present invention.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and working principle etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the control circuit of the automobile starter starting protection of the present embodiment comprises the car accumulator of successively series connection, output loop, starter motor, control unit and the enable switch of relay, control unit has control signal input end and control signal output terminal, can realize break-make under the control of control unit between control signal input end and the control signal output terminal; The low tension power supply of the control signal input end of the control loop of enable switch, relay, control unit and control signal output terminal, automobile is connected successively, to form the low-voltage control circuit of starter motor.
As shown in Figure 1, only have conducting between control signal input end and control signal output terminal, and enable switch is when closed, starter motor just can get electric startup.When disconnecting between control signal input end and the control signal output terminal, even enable switch is closed, because the control loop of relay does not have electric current to pass through, so relay can adhesive, so starter motor can not get electric startup.
The controlling method of the control circuit of above-mentioned automobile starter starting protection is as follows: control unit detects the closed situation of enable switch by the voltage that detects the control signal input end; when the closed frequency of enable switch surpasses preset frequency; or closed interval is when exceeding scheduled duration less than predetermined interval or closing time; control unit disconnects the connection between control signal input end and the control signal output terminal, with the control of shielding enable switch to starter motor.
In addition, control unit links to each other with storage battery sensor and tutorial light for detection of battery condition.Control unit detects battery condition by storage battery sensor, when the storage battery health status is not good, control unit disconnects the connection between control signal input end and the control signal output terminal, with the control of shielding enable switch to starter motor, reports to the police by tutorial light simultaneously.
