Embodiment

[0037] Obviously, many modifications and changes made by those skilled in the art based on the gist of the present invention belong to the protection scope of the present invention.

[0038] A whole vehicle control method for a general mild hybrid electric vehicle of the present invention comprises the following steps: the general vehicle controller assembly is positioned as the highest command and coordination center of the whole vehicle, and its main function is to collect the state of the whole vehicle and judge the driver Consciousness, according to the vehicle control strategy, realizes through the CAN bus protocol:

[0039] First, when the driver wants to start the vehicle, he can control the BSG motor to output a large torque to quickly drive the engine through the collected vehicle status information and according to the vehicle control strategy, and the engine can be dragged to the target speed in a short time;

[0040] Second, control the BSG motor to realize the fun...

Abstract

The invention discloses a complete controller assembly device for a general mild hybrid vehicle and a control method, and belongs to the technical field of mild hybrid vehicles. A communication module exchanges data with other control units through a controller area network (CAN) bus, state information of the complete vehicle is acquired through signals processed by connector wire harnesses and acquisition circuits of analog signals, digital signals and pulse signals, the working state of the vehicle and the driving awareness of a driver are judged, and meanwhile, control commands are sent tothe control unit of each executor so as to realize communication and information sharing among the parts of a system and realize cooperative work and control steps among the parts of the vehicle; anda control panel comprises a double-output power supply module, a voltage stabilizing module, a bus communication module with two CAN transceivers and a K wire transceiver, a 7-channel low side driving module, a 6-chanenl analog signal acquisition circuit, a 5-channel digital signal acquisition circuit, a 2-channel pulse signal acquisition circuit, a main control singlechip and peripheral circuitscomprising a reset circuit and a debugging interface and circuit.

Description

technical field [0001] The invention relates to a vehicle controller assembly device and a control method for a general mild hybrid electric vehicle, belonging to the technical field of mild hybrid electric vehicles. Background technique [0002] During the design and development process of functional prototypes of mild hybrid vehicles, the cooperation with the engine electronic control system (EMS) supplier is crucial, including the modification of some software, the realization of new functions, the modification and optimization of calibration, etc. This requires a relatively long period for technical and commercial consultations, and at the same time requires a large amount of money to complete the entire modification plan. In fact, in the process of functional prototype vehicle design, since the goal is in scheme design and functional realization verification, the modification of the electronic control system can be completed temporarily without urgency, and the design o...
