Problems solved by technology

[0002] For example, the shifting of many small cars and a large number of trucks still relies on the skills of the driver to manually operate. The "automatic dial" forward gear used in existing cars still has multiple manual buttons for adjustment. The structure is also relatively complicated, and the cost is relatively high, so the driver's operation will directly affect the smooth operation of the vehicle and fuel consumption.

Abstract

An autoamtic control system for step speed variator shift of motor-driven vehicle is composed of a step speed variator, a sampler consisting of throttle pedal sensor, engine's rotion speed sensor and vehicle's speed sensor, a comparator, a memory and a executing unit consisting of step motor and multiple control switches connected with related parts. Its advantages are high reliability, correctness and sensitivity, flexible combination, and antitheft and car-search functions.

Description

technical field [0001] The invention relates to a control system for gear shifting of a motor vehicle stepped transmission, in particular to an automatic control system for motor vehicle gear shifting Background technique [0002] For example, the shifting of many small cars and a large number of trucks still relies on the skills of the driver to manually operate. The "automatic dial" forward gear used in existing cars still has multiple manual buttons for adjustment. The structure is also relatively complicated, and the cost is relatively high, so the driver's operation will directly affect the smooth operation of the vehicle and the fuel consumption. Contents of the invention [0003] The purpose of the present invention is to provide a mechanism that can replace the "automatic dial" mechanism used in the current vehicle, which can automatically control the shifting of the stepped transmission on the motor vehicle, and can automatically control the speed of the motor veh...
