Abstract

The invention relates to an electric gear-shifting device with a balanced bridge, which comprises a signal input stage, a balanced bridge circuit and a signal output stage. The signal input stage comprises a gear-up signal input end and a gear-down signal input end, the gear-up signal input end is connected with a first resistor in series, and the gear-down signal input end is connected with a second resistor in series. The balanced bridge circuit comprises a third resistor, a fourth resistor and a fifth resistor; the third resistor is bridged between the first resistor and the second resistor, the fourth resistor is connected between the first resistor and the ground, and the fifth resistor is connected between the second resistor and the ground. The signal output stage comprises a gear-up signal output end and a gear-down signal output end, the gear-up signal output end is connected with the first resistor in series, and the gear-down signal output end is connected with the second resistor in series.

Description

technical field [0001] The invention relates to an electric shifting device with a balanced electric bridge, in particular to an analog electric shifting device with a balanced electric bridge. The analog shifting device can generate different voltages by inputting different signals for up and down gears It can effectively improve the shortcomings of traditional digital gear shifting devices that cause shifting errors caused by accidentally touching up and down gears at the same time. It can reduce shifting time, improve shifting smoothness, and improve system reliability and stability. Background technique [0002] Traditional shift vehicle circuit design uses two identical circuit devices to use individual input voltage signals to determine whether to shift gears, such as figure 1 As shown in the circuit architecture 10 of the conventional digital shift system, the input terminal T 1 , T 2 When it is turned on, the voltage is +5V (volts), and when it is open, the voltage...
