Description

Control system and control method for switching manual-automatic working conditions of commercial vehicle Technical Field The invention belongs to the technical field of commercial vehicles, and particularly relates to a control system and a control method for switching manual and automatic working conditions of a commercial vehicle. Background At present, the actual operation of commercial vehicles still faces multiple realistic challenges such as 'less service', 'high oil price', 'low freight rate', and the like, and these factors significantly increase the operation cost of customers and compress profit margins. Based on the current market environment and operating pressure, higher requirements are put forward by clients on the switching capability of the vehicle between different service modes, the adaptability to different transportation scenes, and the consistency and flexibility of the operation response of the driver in the face of complex working conditions. Therefore, development of a gearbox system capable of integrating various control programs is urgently needed to support seamless switching of customers in different operation scenes, and overall utilization rate and economy of vehicles are improved. At present, all vehicles matched with an AMT gearbox in the domestic commercial vehicle market adopt a curing calibration strategy of 'one-vehicle-one-program', and the flexible adaptability to diversified operation services and complex use scenes is lacking. In order to improve the competitiveness of products in the market segment, the calibration requirements must be further refined according to the dimensions of industry types, typical loads, road conditions, driving habits and the like served by different vehicle types, and targeted working condition adaptation and performance optimization are developed. Through deep system calibration and full actual condition verification, the performance potential of the AMT gearbox can be fully exerted, and the gear shifting smoothness and response speed can be obviously improved, so that the driving experience and the operation confidence are improved, and the market attraction of products is further enhanced. In summary, the existing AMT gearbox technology only integrates a single calibration data set, so that it is difficult to comprehensively cover various operation scenes with significant differences from trunk logistics to municipal engineering, from mountain heavy load to urban distribution, and the like, and thus the composite requirements of customers on flexibility, economy and driving quality cannot be met. Disclosure of Invention Aiming at the problem that the prior art cannot be completely suitable for various scenes due to the integration of one-edition of calibration data, the invention integrates different working condition calibration data through a transmission, realizes different working condition switching through TBOX automatic identification or manual switching, executes corresponding working conditions and is suitable for various car use scenes.
