Problems solved by technology

Therefore, the power supply current is large, and the requirements for the switching tube in the drive circuit are high, resulting in low efficiency
In addition, the control circuit and operating mechanism of most electric AMT actuators are independent and are not integrated into the gearbox, so the power supply line is long, the loss is large, and the electromagnetic interference is serious

Abstract

The invention relates to an electric automation transmission execution mechanism control circuit. The control circuit comprises a boosted circuit, an energy storage capacitor, a select motor driving module, a shifting motor driving module, and a clutch motor driving module; the input end of the boosted circuit is connected with a vehicle power supply network; the output end of the boosted circuit is connected in parallel with the energy storage capacitor and the clutch motor driving module; and the output ends of the select motor driving module, the shifting motor driving module, and the clutch motor driving module are connected with a corresponding select motor, a corresponding shifting motor and a corresponding clutch motor in a driving way. Compared with the prior art, the control circuit saves materials, improves efficiency, reduces the using number of a switching tube and the power of the boosted circuit, and also saves the energy required by finishing one-time gear selecting and shifting and operating a clutch.

Description

technical field [0001] The invention relates to a control circuit, in particular to a control circuit for an actuator of an electric automatic mechanical transmission. Background technique [0002] Among the main types of transmissions in the field of automobile transmission technology, the shaft-fixed manual transmission mode has high efficiency, convenient manufacturing and processing, low cost and high reliability, so it has always been the mainstream technology in the domestic vehicle transmission market. However, the axis-fixed manual transmission method has some problems in the process of vehicle operation, especially in special driving conditions such as starting on a slope. Compared with other types of transmissions, it is inconvenient to operate; in addition, poor timing of shifting will increase fuel consumption and The engine is worn out, and the driver's operation burden is heavy. In the known art, it is proposed to replace the manual shift operation with an aut...
