Abstract

The invention provides an automobile automatic shifting control method, and belongs to the technical field of automobiles. The control method can be used for solving the existing problem that when a vehicle waits for traffic lights, the way how a transmission case automatically switches gears to improve the driving comfortability is not specifically put forward. The control method comprises the following steps: A, in the case of the red light, a TCU (Transmission Control Unit) detects a brake signal sent by a brake pedal displacement sensor, and carries out analytical judgment on the brake signal so as to determine whether a control signal is output to control a shifting mechanism to switch the gears of an automatic transmission case from a D gear to an N gear; and B, when the red light is off and the green light comes, an ECU (electronic control unit) monitors an accelerator pedal opening signal sent by an accelerator pedal position sensor in real time and then sends the signal to the TCU; and the TCU receives the accelerator pedal opening signal, carries out analytical judgment on the signal so as to determine whether a control signal is output to control the shifting mechanism to switch the gears of an automatic transmission case from the D gear to the N gear. The automobile automatic shifting control method provided by the invention has the advantages of reducing gear shift operations, improving the driving comfortability and lowering the oil consumption.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to an automobile automatic shift control method. Background technique [0002] Now, with more and more vehicles in the world, the corresponding vehicle energy oil is less and less, resulting in skyrocketing gasoline prices. Therefore, various automobile manufacturers are working hard to reduce fuel consumption. And through such as start-stop strategy, gasoline engine direct injection strategy, etc. to reduce fuel consumption. In addition, with the improvement of people's living index, everyone's requirements for comfort are gradually increasing. [0003] Automatic transmission control unit, referred to as TCU, is commonly used in automatic transmissions such as AMT, AT, DCT, and CVT. Vehicle automatic transmission is an important part of automobile electronic control technology, which makes driving easier. The use of computer and power electronic drive technology to realize the...
