Problems solved by technology

DCT eliminates the sense of torque interruption when the manual transmission shifts gears, but due to the driver's driving habits, some are economical and some are dynamic. Different types of drivers have different speed requirements, and the existing DCT Can not automatically identify the type of driver, so it can not meet the driver's comfort

Abstract

The invention discloses a car driver type recognition method which comprises the following steps: 1, signal acquisition and processing: through a CAN equipment driving module and a CAN information processing module, a TCU processes data frames between the TCU and an ECU as well as those between the TCU and an ABS, so as to acquire real-time engine speed, accelerator, footbrake and car speed signals; 2, through an accelerator differential signal calculation module, the TCU averages the accelerator signals, so as to acquire an accelerator average signal; 3, through a drive type recognition fuzzycontrol system module, the TCU calculates a driver factor according to the real-time engine speed, accelerator, footbrake, key switch, handle position and car speed signals; 4, driver factor normalization processing: through a driver factor normalization module, the TCU processes the driver factor through normalization; and 5, through a driver factor filtration module, the TCU processes the normalized driver factor through filtration. By adoption of the car driver type recognition method disclosed by the invention, a driver type can be automatically recognized, and then the optimal gear for car driving can be adjusted.

Description

technical field [0001] The invention relates to the field of automotive electronic control, in particular to a vehicle driver type identification method. Background technique [0002] Since the advent of dual-clutch transmission (DCT), due to its high transmission efficiency, mechanical compactness, reliable operation, and low price, it has been favored by major automobile manufacturers since the 1980s, especially in recent years. Automobile or transmission parts suppliers are increasing the research and development of DCT, making DCT more and more mature. DCT is based on manual transmission and is different from automatic transmission. In addition to the flexibility of manual transmission and the comfort of automatic transmission, DCT can also provide uninterrupted power output. Compared with the traditional manual transmission, DCT uses the new technology of DCT, which makes the manual transmission have automatic performance and greatly improves the fuel economy of the ca...
