Abstract

The invention relates to a parking linkage method and device based on an AMT (Automatic Mechanical Transmission), which is characterized in that a pressure relay is additionally arranged between a hand-operated valve output port of a parking system and a differential relay valve; the signal output of the pressure relay is connected to a TCU (Transmission Control Unit) or a VCU (Vehicle control unit); meanwhile, an input port of the differential relay valve is plugged; an electromagnetic valve is connected in parallel with the output port of the differential relay valve, and the opening of the electromagnetic valve is controlled by the TCU or the VCU; and an input port P of the electromagnetic valve is connected with the output port of the differential relay valve, and two output ports A and B of the electromagnetic valve are respectively connected with a parking air reservoir or atmosphere. The forced parking, release of parking brake to start up, and parking brake through a control rod can be realized according to the fact that the TCU or the VCU controls the electromagnetic valve to be in the opening state after the signal collected by the pressure relay is analyzed and judged by the TCU or the VCU.

Description

technical field [0001] The invention relates to a component structure of an automobile, in particular to an automobile parking linkage device assembled with an automatic shift transmission AMT, which is suitable for a power brake system using compressed air and a parking system based on an energy storage spring composite brake air chamber. Various types of vehicles installed, including hybrid and pure electric vehicles. Background technique [0002] AMT automatic shifting transmission (electromechanical transmission) realizes automatic shifting through electronically controlled mechanical shifting. It is based on traditional mechanical transmissions and dry clutches. Electrification transformation, using electronic control technology and various sensors, the transmission controller (TCU) analyzes and processes the engine working status (such as power and speed), vehicle speed, accelerator, braking and road conditions, etc., and controls the engine The controller (ECU) and t...
