Embodiment Construction

[0019] The technical solution of the present invention is to use the AMT shifter of conventional fuel vehicles to realize manual shifting and automatic shifting. When shifting manually, by manipulating the shift lever to 6 functional positions such as figure 1 , to the vehicle controller with the switching signal of the output gear as shown in Table 1.

[0020]

[0021] Table 1

[0022] The interface pin definition of switch signal is as follows: figure 2 , there are switch signal 1, switch signal 2, switch signal 3, and switch signal 4. The vehicle controller judges the gear position according to the switch signal combination corresponding to these 6 functional positions, and then sends a gear shift confirmation command based on the current state of the vehicle, and finally changes the power output value range of the current gear position through the motor controller, and displays the gear position On the instrument cluster, the variable spe...

Abstract

The invention aims to solve the technical problem of providing a method for automatic-manual transmission gear shifting for an electronic automobile, and executing four forward gears and one backward gear by adopting an automatic-manual transmission gear shafting mechanism and adding a control strategy. According to the method, manual gear shifting and automatic gear shifting are realized by means of an AMT (automatic-manual transmission) gear shifting device of a normal fuel oil automobile; a gear shifting rod is controlled to six function positions when in manual gear shifting to output switch signals of gears to a finished automobile controller; the gears are judged by the finished automobile controller according to the switch signal combination corresponding to the six function positions; then gears changing confirmation orders are transmitted by combining the current state of the automobile; and finally the motive output value domain of the current gears is changed through a motor controller, and the gears are displayed on a combination meter to realize speed changing.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to a manual and automatic gear shifting method for electric vehicles. Background technique [0002] The motor characteristics of pure electric vehicles determine that the maximum torque can be output at low speeds, and the acceleration ability is strong. In order to reduce the efficiency loss of mechanical transmission, a fixed speed ratio method of decelerating the motor by a first-stage reducer is directly adopted, unlike traditional fuel oil. Cars change gears in a physical way. The driver can accelerate and step on it, and it can reach a high speed in a few seconds, and the characteristic of electric vehicles is that it is very quiet, so there will be great hidden dangers to the safety of pedestrians and themselves, especially the driver's mistakes It is even more dangerous when driving, because even an electric car driving at high speed behind a pedestrian may not ...
