Abstract

The invention relates to the field of vehicle variable speed control research design, in particular to an electronic control system of a vehicle parallel connection planetary gear train transmission. The electronic control system comprises a processing module and a power drive module. The processing module receives signals of sensors, such as an engine rotating speed sensor, a throttle percentage sensor, a vehicle speed sensor and a hand control valve position sensor, related to vehicle variable speed control and carries out logical analysis processing on the signals to form control signals, the control signals are output to the power drive module, the power drive module drives all electromagnetic valves of a vehicle parallel connection planetary gear train transmission hydraulic control servo system under the control of the control signals, and gear shifting control over the transmission is achieved.

Description

technical field [0001] The invention relates to the field of vehicle speed change control research and design, in particular to an electronic control system of a vehicle parallel planetary gear train transmission. Background technique [0002] Vehicle transmissions are divided into manual transmissions and automatic transmissions. Manual transmissions are shifted manually and cannot realize automatic transmission functions; automatic transmissions can realize automatic transmissions and are divided into mechanical automatic transmissions (AMT) and power shift automatic transmissions ( AT), continuously variable transmission (CVT) and dual clutch transmission (DSG). At present, the automatic shift function of the automatic transmission is generally realized by controlling the shift servo and execution system through the transmission electronic control unit (TCU); The valve is used as a servo control element to control the actuator of the shift execution system to realize aut...
