A kind of electric tail gate control system for street rod is disclosed in the prior art, and automobile is equipped with former vehicle, former vehicle Car door and former lock button, the electric tail gate control system for street rod include lock motor, enabling motor, lock motor Position sensor, enabling motor position sensor, automobile tail gate control ECU, and it includes CPU, signal processing that automobile tail gate, which controls ECU, Device, motion motor controller, kinematic parameter communicator, kinematic parameter communicator and extraneous PC machine communicate, the operation pair in PC machine The parameter of signal processor and motion motor controller is configured, CPU analysis processing lock motor position sensor and Signal, the collected original ECU signal of signal processor of enabling motor position sensor transmission, drive the control of motion motor controller Lockmaking button motor and enabling motor.

But automobile tail gate control box has a characteristic, two poles must be worked at the same time and be rotate in same direction.Have same Stress.The case where not considering client's pulling two motors can be driven with same group of motor driving.But tail-gate pulls Function (user's manual switch tail-gate) is existing for meeting certainly, and during pulling, motor power generation loads each other, this will be damaged Car door, and traditional tail-gate control box also needs individual motor all the way to control to inhale lock to electricity, therefore, solves this The problem of class, is particularly important.

Summary of the invention

In view of the above-mentioned problems, utilizing two-way strut motor the present invention provides a kind of automobile power back door ECU control system The multiplexing pull-out of wherein two-way is controlled electricity suction lock as third control circuit and used by work characteristics in the same direction while circuit, this Sample just saves one group of control integrated circuit, to play the role of saving cost.

In order to realize above-mentioned technical proposal, it to include tail that the present invention provides a kind of automobile power back door ECU control systems Door control box, the tail-gate control the motor driving module that two motors of control are provided in box, and the motor is for going up and down The strut motor of automobile tail gate, the output end of the motor driving module are electrically connected with motor, and the motor driving module includes There are the first motor driving module and the second motor driving module, by first motor driving module and the second motor driving module Two strut motors for going up and down automobile tail gate are controlled respectively.

Further improvement lies in that: two strut motors work at the same time and lead to rotation, and there are same stress；By two Circuit when a strut motor multiplexing pulls out controls electricity suction lock as third control circuit and uses.

Further improvement lies in that: when the voltage of the strut operation of automobile tail gate, the MR- and ML- of circuit is equal, even The motor both ends being connected to herein do not have voltage difference, and will not work.

Further improvement lies in that: when needing third control circuit operation, it is only necessary to which MR+ and ML+ are arranged to vacantly State, MR- and ML-'s is arranged to be grounded all the way, and another way connects power supply, and third control circuit can be allowed to work, thus mutually not It influences.

Further improvement lies in that: the MR+ of strut motor circuit and MR- are arranged to be grounded or connect power supply, guaranteed The MR+ and MR- of circuit do not have voltage difference and MR- and ML- to have voltage difference, so that third control circuit works.

The beneficial effects of the present invention are: the present invention utilizes the work characteristics of two-way strut motor simultaneously, in the same direction, wherein two Strut motor multiplexing in road, which pulls out, is used as third control circuit to control electricity suction lock and use, and thus saves one group of control integrated circuit, Play the role of saving cost, that is, achievees the effect that two-way controls No. three motors.
