Embodiment Construction
[0029] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0030] A vehicle engine automatic speed control device, its composition diagram is as follows figure 1 As shown, it includes an excitation current sampling circuit 1, a control circuit 2, a drive circuit 3, and a push rod motor 4. The push rod of push rod motor 4 is connected with vehicle accelerator pedal. In this embodiment, the push rod motor 4 is a DC motor. The drive circuit 3 includes a battery and an H-bridge.
[0031] The excitation current sampling circuit 1 measures the excitation current value of the vehicle-mounted generator 7, then converts the excitation current value into a voltage signal and outputs it to the control circuit 2; the control circuit 2 judges according to the voltage signal, and outputs the drive signal ...
