Abstract
The utility model provides a universal starting system of an automatic gearshift automobile, which comprises a key switch, a relay, a starting motor, a gear shifting device, a shift lever position sensor, an automatic transmission control unit and a power supply, wherein the gear shifting device, the shift lever position sensor and a signal wire of the automatic transmission control unit are connected with the relay for controlling the work of the relay, and the key switch is connected with the starting motor by the relay. The system is additionally provided with a universal starting switch, the wiring harness at one end of which is connected with an output line of the key switch, and the wiring harness at the other end thereof is connected with an input line of the starting motor. When the universal starting switch is pressed down, the key switch can be directly connected with the starting motor. Therefore, the control of the gear shifting device, the automatic transmission control unit (TCU), the shift lever position sensor and a starting motor relay can be skipped, and the starting of an engine is not influenced when error occurs in the parts.
Description
Technical field
The utility model relates to technical field of automotive electronics, is specifically related to the starting circuit of automobile.
Background technique
Automatic transmission vehicle rules and regulations only just allow to start vehicle when Parking shelves (P) shelves and neutral gear (N) shelves.Generally before actuating motor, add relay, provide signal by selector, gear position sensor or control unit for automatic shift (TCU) when Parking shelves (P) shelves and neutral gear (N) shelves then, make actuating motor energising running, to start vehicle.But, can not correctly provide electric signal, then the fail to start vehicle when selector, gear position sensor or control unit for automatic shift (TCU) when breaking down.
So following situation can occur: when automobile on the expressway or blowing out appears in waste hill woods and during fault such as above components and parts damage, if when weather condition is badly wanted to open air-conditioning, can't realize because can't pilot engine; When perhaps wanting to fix a breakdown, do not know that the actuating motor fault still is control unit for automatic shift (TCU), perhaps selector or gear position sensor, the perhaps fault of actuating motor relay yet; Or the like.Particularly vehicle adopt control unit for automatic shift (TCU) software control output electric signal mostly, and the possibility that control unit for automatic shift (TCU) software breaks down can't be estimated, can bring more trouble in order to save cost at present.
Summary of the invention
The purpose of this utility model provides a kind of omnipotent starting system of automatic transmission car, this system is by using a kind of electric switch, make no matter what gear selector is in, when any fault appears in selector, gear position sensor or control unit for automatic shift (TCU), when pressing this switch, can both skip above element, the circuit of actuating motor is connected, can cross key operation and make actuating motor work, thereby make vehicle launch.
The technical solution of the utility model is as follows:
A kind of omnipotent starting system of automatic transmission car, described starting system comprises key operation, relay, actuating motor, selector, gear position sensor, control unit for automatic shift and power supply, the signaling line of described selector, gear position sensor and control unit for automatic shift is connected relay, control relay work, key operation then connects actuating motor by relay.
Under to the immovable situation of existing structure, be provided with an omnipotent switch starter in the native system in addition, an end line bundle of described omnipotent switch starter connects the output line of key operation, the input line of the actuating motor that the other end wire harness connects.
Native system under normal circumstances is by the work of normal control route, promptly provide SC sigmal control actuating motor relay, by the connection between actuating motor relay control key operation and the actuating motor by selector, control unit for automatic shift (TCU) or gear position sensor.And when breaking down with upper-part, just can press omnipotent switch starter, directly key operation and actuating motor are connected, the control of so just skipping selector, control unit for automatic shift (TCU), gear position sensor, actuating motor relay can not influence the starting of motor.
Description of drawings
Fig. 1 is the schematic block circuit diagram of native system,
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is made further detailed presentations.
As shown in Figure 1, this starting system comprises key operation 2, relay 3, actuating motor 4, selector 5, gear position sensor 7, control unit for automatic shift (TCU) 6 and power supply, and other increases by an omnipotent switch starter 1.Native system portion changes the some Placement of original system, selector 5, gear position sensor 7 and control unit for automatic shift 6 still adopt the existing variety of way of prior art to be connected relay by signaling line, control relay 3 work, key operation 2 is also the same with existing starting system to connect actuating motor 4 by relay 3.And an end line bundle 8 of the omnipotent switch starter 1 that is provided with in addition directly connects the output terminal of key operation 2, the input end of the actuating motor 4 that the other end wire harness 9 connects.
Existing automatic transmission starting control principle is: have only the automatic transmission vehicle to be in Parking shelves (P) shelves and neutral gear (N) shelves just allow actuating motor work, thereby start vehicle.Therefore, by the work of key operation 2 control actuating motors 4, by 3 safety effects of actuating motor relay, have only when 3 work of actuating motor relay between key operation 2 and the actuating motor 4, key operation 2 could be controlled the work of actuating motor 4.And whether actuating motor relay 3 works by selector 5 or control unit for automatic shift (TCU) 6, perhaps the signal deciding that provides of gear position sensor 7 grades.This signal is to have only just to send low level (0V) voltage when vehicle is in Parking shelves (P) shelves and neutral gear (N) shelves.This moment, the transfer route of electric current was: by key operation 2 → actuating motor relay 3 → actuating motor 4.
And native system is by having increased omnipotent switch starter 1, when selector 5, perhaps control unit for automatic shift (TCU) 6, when perhaps gear position sensor 7 or actuating motor relay 3 break down, press omnipotent switch starter 1, promptly connect circuit, so just can skip above equipment, directly by key operation 2 control actuating motors 4.This moment, the transfer route of electric current was: by the other end wire harness 9 → actuating motor 4 of an end line bundle 8 → omnipotent switch starter 1 → omnipotent switch starter 1 of key operation 2 → omnipotent switch starter 1.
Certainly, present technique can expand to and send an electric signal when omnipotent switch starter is worked, this signal and selector 5 or control unit for automatic shift (TCU) 6, perhaps gear position sensor 7 gives the signal of relay consistent at Parking shelves (P) shelves with neutral gear (N) shelves, to replace above element.
This omnipotent switch starter is the switch that is of little use, and has only in the time of can't lighting a fire when breaking down just usefulness, therefore should put into more hidden place to this switch, following etc. such as following, the seat of console, and in operating instruction, illustrated.
