Abstract

The invention provides an electric vehicle parallel energy recovery classification control system and method. The system includes a vehicle controller, a motor, and a signal acquisition unit; the signal acquisition unit communicates with the vehicle controller through a CAN bus; the vehicle controller communicates with the vehicle controller through The CAN bus communicates with the motor; the signal acquisition unit is used to collect energy recovery information and transmit it to the vehicle controller; the vehicle controller receives the energy recovery information and controls the motor to execute the energy recovery mode; adopting the above scheme can effectively improve the energy recovery of the vehicle. The energy recovery efficiency of the vehicle improves the driving performance of the vehicle. At the same time, the function configuration of the electric vehicle is increased, and the user experience of the electric vehicle is enhanced. Competitiveness in the market.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle braking energy recovery, and in particular relates to an electric vehicle parallel energy recovery step-by-step control system and method. Background technique [0002] Braking energy recovery is one of the effective measures to improve the energy utilization rate of electric vehicles; according to the different structures and strategies, the braking energy recovery system can be divided into "parallel" recovery system and "series" recovery system; due to the structure Due to different factors such as cost and control implementation difficulty, most electric vehicle braking energy recovery systems on the market still use "parallel connection"; "parallel connection" braking energy recovery can be divided into two types: coasting recovery and braking recovery. process; from a structural point of view, the "parallel" braking energy recovery is only a modification of the prototype vehicle. Du...
