Acceleration traction control method for diesel motor vehicle

Abstract

The invention relates to a traction control method for a diesel motor vehicle, in particular to an acceleration traction control method for the diesel motor vehicle, which comprises seven steps of: outputting an acceleration gear signal of a traction handle; outputting a required power gear signal of a traction inverter assembly; outputting a diesel engine rotating speed gear control signal of anon-vehicle central microcomputer; outputting generator excitation current of the on-vehicle central microcomputer; outputting a feedback power gear signal of the on-vehicle central microcomputer, outputting a power gear comparison of a traction control unit; and converting alternating-direct-alternating current, wherein each step adopts security protection control and bus technology to transmit signals. Compared with the conventional output power traction control method for the diesel motor vehicle, because a driver can directly control the speed changes of a train, the acceleration traction control method for the diesel motor vehicle greatly reduces the operation difficulties for the driver to drive at a controlled speed under a complex road condition, and achieves the functions of raiding the speed at a fixed acceleration and cruising at a fixed speed. The driver pulls the traction handle to change the gear so that the train can run at the acceleration determined by the traction handle.

Description

technical field [0001] The invention relates to a traction control method of a diesel train, in particular to an acceleration traction control method of a diesel train, and is especially suitable for a traction control system of an AC drive type diesel train. technical background [0002] There are two traction control methods for traditional diesel trains: one is to control the speed of the diesel engine, and the other is to control the torque of the diesel engine. In the first method, what the driver actually controls is the rotational speed of the diesel engine; in the second method, what the driver actually controls is the output torque of the diesel engine. When the train wants to increase the speed, the driver has to pull the handle to increase the speed or output torque of the diesel engine. Although the speed will increase upwards, it is extremely difficult to accurately fix the speed on a certain speed value; When the vehicle speed is high, the driver has to pull t...
