Abstract
The utility model relates to a control system capable of preventing a vehicle from rushing forward in the engine starting process. The control system comprises a neutral position switch unit, a clutch switch unit, a starter relay and an ECU, wherein the neutral position switch unit transmits a neutral position switch signal to the ECU, the clutch switch unit transmits a clutch switch signal to the EUC, the starter relay receives a response signal sent by the ECU, the neutral position switch unit and the clutch switch unit are connected with input ends of the ECU respectively, and the starter relay is connected with the output end of the ECU. The ECU outputs the response signal to the starter relay and a buzzer after receiving the neutral position switch signal, the clutch switch and an ignition switch signal, and therefore the problem that the vehicle rushes forward in the starting process due to the misoperation of a driver, namely, the gear is not in the neutral position or a clutch is not stepped downward, is effectively solved.
Description
Technical field
The utility model relates to the control system that a kind of preventing engine starts preshoot.
Background technique
Traditional engine start is to open ignition switch by ignition key, controls cranking-motor relay, thus ato unit.In practical operation, if driver gear is not placed in neutral or not let slip the clutch just open ignition switch, be easy to cause the automobile starting preshoot, vehicle and pedestrian are caused to danger.ECU(ECU configuration for control engine) be used to control a plurality of controlled object equipment relevant to engine control, to improve the performance of motor.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned defect, and a kind of control system of preventing engine startup preshoot is provided, and avoids causing due to driver's misoperation the problem of vehicle launch preshoot.
The utility model solves the technological scheme that its technical problem adopts: provides a kind of preventing engine to start the control system of preshoot, comprises neutral position switch unit, clutch switch unit, cranking-motor relay and ECU, wherein:
The neutral position switch unit, for flowing to described ECU by the neutral position switch signal;
The clutch switch unit, for flowing to described ECU by the clutch switch signal;
Cranking-motor relay, the response signal sent for receiving described ECU;
Described neutral position switch unit is connected with the input end of ECU respectively with the clutch switch unit, and described cranking-motor relay is connected with the output terminal of ECU.
Also comprise that being connected to the ECU output terminal sends the buzzer of response signal for receiving ECU.
Also comprise and be connected to the ignition switch unit of ECU input end for delivery of the ignition switch signal.
The utility model compared with prior art, beneficial effect is: ECU is by receiving neutral position switch signal, clutch switch signal and ignition switch signal, the output response is to relay and buzzer, thereby control engine starts, effectively avoided misoperation (gear is not placed in neutral or does not step on clutch) due to the driver to cause the problem of vehicle launch preshoot.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
The schematic diagram that Fig. 1 is the utility model control system.
Embodiment
As shown in Figure 1, a kind of preventing engine starts the control system of preshoot, comprise neutral position switch unit 1, clutch switch unit 2, ignition switch unit 3, cranking-motor relay 5, buzzer 6 and ECU4, wherein: neutral position switch unit 1, clutch switch unit 2 and ignition switch unit 3 are connected with the input end of ECU4 respectively, and cranking-motor relay 5 is connected with the output terminal of ECU4 respectively with buzzer 6.Neutral position switch unit 1 flows to ECU4 by the neutral position switch signal, clutch switch unit 2 flows to ECU4 by the clutch switch signal, ignition switch unit 3 flows to ECU4 by the ignition switch signal, simultaneously, ECU4 will carry out, after the logic judgement, response signal is flowed to cranking-motor relay 5 and buzzer 6 to neutral position switch signal, clutch switch signal and the ignition switch signal of carrying, and cranking-motor relay 5 and buzzer 6 are made corresponding response for response signal.
When neutral position switch unit 1 and ignition switch unit 3, during simultaneously in on-state, ECU4 sends response signal, conducting cranking-motor relay 5, thus starter motor drags engine start, and buzzer 6 is in off state; When clutch switch unit 2 and ignition switch unit 3, during simultaneously in on-state, ECU4 sends response signal, conducting cranking-motor relay 5, thus starter motor drags engine start, and buzzer 6 is in off state; When neutral position switch unit 1 and clutch switch unit 2, during simultaneously in off state, ignition switch unit 3 is when on state, and ECU4 sends response signal, conducting buzzer 6, the reminding user gear is not placed in neutral, misoperation, and now cranking-motor relay 5 is in off state.Figure is as shown in table 1 for the ECU input/output state.
Wherein, " 1 " means that ON(connects), " 0 " means that OFF(disconnects), " x " means ON or OFF.
From described above, ECU is by receiving neutral position switch signal, clutch switch signal and ignition switch signal, and the output response is to cranking-motor relay and buzzer, thereby control engine starts.When the ignition switch signal is effective, when the connection of neutral position switch unit or the connection of clutch switch unit, the conducting cranking-motor relay, thereby starter motor drags engine start, gearbox separates with motor, now opens the igniting switch element, can not cause the automobile preshoot; When neutral position switch unit or clutch switch unit access failure, cranking-motor relay is conducting not, starter motor can not drag engine start, gearbox does not separate with motor, now opens the igniting switch element, and automobile can not start, buzzer gives the alarm, remind the driver gear need to be placed in to neutral or step on clutch, thereby avoid the misoperation due to the driver, cause the vehicle launch preshoot.
The above is described embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection domain of the present utility model.
