Embodiment Construction

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

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

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 method for calibrating a hybrid electric vehicle controller based on the CCP protocol relates to a hybrid electric vehicle, especially the monitoring technology field of a hybrid electric vehicle controller. Background technique [0002] The hybrid electric vehicle controller needs to go through a matching calibration process from the development of a prototype to the formation of a product to determine its operating parameters and control parameters; in addition, during the test process, the test personnel need to be able to monitor the changes in 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 development of hybrid electric vehicle controllers. [0003] At present, the prior art hybrid electric vehicle controller calibration system uses SCI serial communication to define a series of calibration rules. This method has the following shortcomings: [0004] 1) ...
