Abstract

The invention discloses a gearbox control method and system based on self-adaptive cruise. The gearbox control method comprises the steps that after self-adaptive cruise is started, a deceleration control signal of self-adaptive cruise is detected in real time; according to the deceleration control signal, the cruising condition of a vehicle is determined; when the vehicle is in a cruising acceleration or cruising constant speed condition, gear and clutch control is conducted according to a conventional mode; the conventional mode is a gearbox control mode when self-adaptive cruise is not started; when the vehicle is in a cruising deceleration condition, whether the vehicle is in an emergency braking state or not is determined; if not, gear and clutch control is conducted according to theconventional mode; if yes, a clutch is controlled to be separated; and when the vehicle is in a cruising parking condition, wriggle idle speed control of an engine is forbidden in an energy forbiddingmode, and the pressure of the clutch is controlled below the kisspoint. Through vehicle state judgment on an ACC relative state signal, gearbox control under the ACC effect is achieved, and thus thevehicle can travel or park stably and safely.

Description

technical field [0001] The invention relates to the field of wet dual-clutch gearbox control, in particular to a gearbox control method and system based on adaptive cruise. Background technique [0002] On the one hand, the dual-clutch automatic transmission is one of the most advanced transmissions in the world at present. A typical wet dual-clutch automatic transmission establishes the pressure of the main oil circuit through the rotation of the oil pump, and then the electronic control system judges the current state of the vehicle and the transmission. Working state, so as to control the solenoid valves related to gear control and clutch control in the hydraulic system, realize the selection and shift of the gearbox and the separation and combination of the clutch, and finally achieve good vehicle driving performance. [0003] On the other hand, with the rapid development of automobile intelligence, the application of various new automotive electronic systems in vehicles...
