Embodiment 1

[0036] combine figure 1 , figure 2 and image 3 Describe this embodiment, in this embodiment, a kind of P2 architecture hybrid idle speed control method involved in the present invention, it comprises the following steps:

[0037] Step 1. Determine whether the whole machine system enters the idle state. If it is satisfied, it will enter the idle state. If it is not satisfied, it will exit the idle state;

[0038] Step 2: After entering the idling state, the vehicle controller HCU sends the motor target idle torque value to the micro control unit MCU, and the micro control unit MCU executes the instructions of the vehicle controller HCU to control the operation of the motor, and the motor executes the torque according to the target torque control to realize driving under idling conditions.

[0039] More specifically: in step 1, the said judging whether the whole machine system enters the idle state, while satisfying:

[0040] 1) Soc threshold is greater than 25%,

[0041...

Abstract

A P2 architecture hybrid idle speed control method, which belongs to a motor idle speed control method. Aiming at the defects of high fuel consumption, high emission pollution, unsafe and unstable in the existing idling method, the present invention provides a P2 architecture hybrid idling control method with no fuel consumption, no pollution, safety and stability. A P2 architecture hybrid idle speed control method involved in the present invention judges whether the whole machine system enters the idle speed state, if it is satisfied, enters the idle speed state, if not, exits the idle speed state; after entering the idle speed state, through the vehicle control The controller HCU sends the motor target idle torque value to the micro control unit MCU, and the micro control unit MCU executes the instructions of the vehicle controller HCU to control the operation of the motor, and the motor performs torque control according to the target torque to realize driving under idling conditions. The invention is mainly applied to controlling the fuel consumption and emission level of the idling working condition.

Description

technical field [0001] The invention belongs to a method for controlling the idle speed of a motor. Background technique [0002] At present, with serious environmental pollution problems and increasingly stringent fuel consumption regulations, it is difficult for traditional powertrains to meet regulatory requirements, and hybrid technology is the development direction to solve this problem. For traditional powertrains, effective control of fuel consumption and emission levels under idling conditions is the most critical factor to reduce fuel consumption and emission levels of the whole machine. However, due to mechanical structure and constraints on power demand, it is difficult to balance and cannot achieve need. [0003] Therefore, there is a need for a fuel-free, pollution-free, safe and stable hybrid idle speed control method. Contents of the invention [0004] Aiming at the defects of high fuel consumption, high emission pollution, unsafe and unstable in the exist...
