System and method for optimizing new energy vehicle whole vehicle control parameters based on Internet

Abstract

The invention provides a system and a method for optimizing new energy vehicle whole vehicle control parameters based on Internet. A control system is constituted by an ECU, a cell phone, and a cloud platform. The ECU comprises a main CPU, a slave CPU, and a GPRS / GPS / bluetooth integration module. The ECU can be respectively communicated with the cell phone and the cloud platform by the bluetooth or the GPRS, and also can be respectively communicated with the cell phone and the cloud platform by the WiFi_Direct or the WiFi_Station. The cell phone is connected with the cloud platform by the WiFi or the 2G / 3G / 4G data network. When the main CPU of the ECU is used to receive the MAP transmitted by the CPU or the GPRS / GPS / bluetooth integration module, the RAM area can be provided with the space corresponding to the MAP, and the original MAP can be copied to the RAM area, and then the original MAP can be erased, and the new MAP can be written in the Flash, and therefore the main CPU can use the new MAP. The system and the method provided by the invention are advantageous in that by adopting various communication ways, the recalibrating of the MAP parameters can be realized without being limited by the vehicle positions and the time, and then the MAP parameter optimization can be realized, and the high-efficiency operation of the vehicle can be maintained, and in addition, the minimum labor cost and the minimum material cost are required.

Description

technical field [0001] The invention relates to the field of the Internet of Things and provides a method for optimizing control parameters of new energy vehicles based on the Internet using a vehicle electronic control unit with a dual-CPU structure, a mobile phone and a cloud platform. Background technique [0002] The operation of new energy vehicles is controlled by the vehicle electronic control unit ECU (Electronic Control Unit), so the control data in the ECU determines whether the new energy vehicles can work normally. In other words, even if the mechanical system and electronic control system of the new energy vehicle are completely normal, if the control data is inappropriate, the vehicle may not be able to operate at all, or the operating effect may not meet the design expectations. Therefore, a complete "calibration" of the control parameters of new energy vehicles is an important part of keeping new energy vehicles in good working condition. [0003] The contro...

Problems solved by technology

If the vehicle is not returned to the factory for recalibration, the data cannot be replaced. Therefore, when the vehicle operating environment changes, the driver's driving habits change, and the vehicle state changes, the MAP in the existing new energy vehicle control unit cannot be adjusted accordingly. Yes, this will lead to reduced efficiency, worse driving experience and even hardware damage
