Starter motor M is connected with the motor of vehicle through driving mechanism, thereby drives engine rotation.
Below, with reference to the mode of execution of figure 1, the working principle of the motor tele-control system that detailed description use the utility model provides.
At first the key operation in the operator cabin 2 must be in " igniting " position, promptly be in " ON " state, make full car energising.Start operator cabin then, just make operator cabin locking switch S 1 closure; Pull on parking brake, just make Parking switch S 2 closures; Make the gear of vehicle be in neutral position, even neutral switch S3 closure.When operator cabin locking switch S 1, Parking switch S 2 and neutral switch S3 were all closed, the remote activation interlocking end of ECU 1 can detect low potential, promptly can realize the following every function to the motor telecontrol this moment.
The startup of motor:
The first button R0 and the maintenance of pressing earlier on the motor tele-control system panel are not put, R1 and keep not putting again pressed ﹠ hold within 3 seconds for example, this moment, the remote activation locking end of ECU 1 was exported Engine Start Signal (if motor starts, then remote activation locking end can not exported Engine Start Signal), thereby the control end of first relay J 1 gets, the normally-closed contact of the relay J 1 of winning is disconnected, and normally opened contact is connected.It is electric that thereby the control end that makes the 3rd relay J 3 gets, and makes the normally opened contact of the 3rd relay J 3 connect.Then the control end of second relay J 2 gets electricly, makes the normally opened contact of second relay J 2 connect.Starter motor M connects power supply and gets electricly like this, and starter motor M drives engine rotation, and ECU 1 controls oil sprayer and carry out oil spout, thereby makes engine start.Behind the engine start, unclamp the first button R0 and the second button R1.
The jiggering of motor:
The first button R0 and the maintenance of pressing earlier on the motor tele-control system panel are not put, for example pressing the second button R1 in less than 7 seconds time range greater than 3 seconds, unclamp the first button R0 and the second button R1 then, this moment, the remote activation locking end of ECU 1 was exported motor jiggering signal, thereby the control end of first relay J 1 gets, the normally-closed contact of the relay J 1 of winning is disconnected, and normally opened contact is connected.It is electric that thereby the control end that makes the 3rd relay J 3 gets, and makes the normally opened contact of the 3rd relay J 3 connect.Then the control end of second relay J 2 gets electricly, makes the normally opened contact of second relay J 2 connect.Starter motor M connects power supply and gets electricly like this, and starter motor M drives engine rotation, and ECU 1 controlled and made not oil spout of oil sprayer this moment, and motor can't start like this.Starter motor M will drive engine rotation to be stopped after 15 seconds.
Stopping of motor:
After the normal operation of motor, press the first button R0 and the second button R1 on the motor tele-control system panel simultaneously, then the remote activation locking end of ECU 1 is exported engine halt signal, the control end of described first relay J 1, second relay J 2 and the 3rd relay J 3 all cuts off the power supply, and motor will stop immediately.
According to motor tele-control system of the present utility model owing to have operator cabin locking switch, Parking switch and a neutral switch; make when can only at the same time operator cabin be started, pull on parking brake and vehicle being hung over neutral gear and could carry out remote activation, jiggering, shutdown, increase idling and reduce operation such as idling vehicle motor; improved the Safety performance of motor tele-control system; can be under the prerequisite of assurance personnel and vehicle safety from energy; the permission maintenance man realizes the telecontrol to motor under car, greatly facilitate maintenance man's operation.
