Embodiment Construction

[0065] The specific embodiment of the present invention will be described with reference to the accompanying drawings.

[0066] As shown in Fig. 1, the system adopted in the embodiment of the present invention is composed of a host PC and a hybrid electric vehicle powertrain controller. The upper host is composed of a PC with a CAN bus interface card and the upper host software. The PC of the example of the present invention adopts an IBM A22m notebook, and its CAN bus interface card is the LAPCAN-II card of KVASER Company. The lower controller is made up of a microprocessor containing the CAN port, the CAN bus driver and the lower controller software. The example of the present invention adopts the microprocessor MPC555, and its CAN module output CNTX and input CNRX ports are connected to the CAN bus driver, and the bus driver adopts a chip 82C250. A pair of twisted wires (CAN_L, CAN_H) constitute the bus. The CAN bus interface card of the PC and the CAN driver of the lower ...

Abstract

A calibration method based on CCP protocol for the controller of electric car with mixed power features that between the low-class controller and upper-class host, which are connected via CAN bus, the upper-class host can initialize the low-class controller and calibrate and monitor its parameters according to CCP protocol.

Description

technical field [0001] The hybrid electric vehicle controller calibration method based on the CCP protocol relates to the hybrid electric vehicle, especially the monitoring technical field of the hybrid electric vehicle controller. Background technique [0002] The hybrid electric vehicle controller needs to go through a process of matching and calibration from the research and development of the prototype to the formation of the product to determine its operating parameters and control parameters; in addition, during the test, it is necessary for the test personnel to be able to monitor the changes of some parameters in the controller in real time. Therefore, A calibration process is needed to complete the above work, which is a basis for the research and development of hybrid electric vehicle controllers. [0003] At present, the hybrid electric vehicle controller calibration system in the prior art adopts SCI serial communication and defines a series of calibration rules ...
