However, when the integral accumulation is very large, but the saturation threshold has not been reached, it cannot play a very good role.
Lowering the threshold will affect the normal control

Embodiment Construction

[0022] A detailed description will be given below in conjunction with the accompanying drawings.

[0023] figure 1 and figure 2 As shown, the present invention provides a method for improving the driving feeling of an industrial vehicle, which is used to solve the problem that the driving feeling of the vehicle, especially the heavy-duty industrial vehicle, does not match the actual speed and the command speed when driving, which is different from the normal situation. problem of difference. Industrial vehicles are different from ordinary civilian vehicles. Their operating parameters such as load size, load range, passing road conditions, and changes in the center of gravity of the vehicle body are different from civilian vehicles. Taking a heavy-duty new energy electric forklift as an example, when driving on a slope During the process, if the driver releases the accelerator to seek vehicle braking, the correct and ideal situation is that the vehicle responds to the driver...

Abstract

The invention relates to an industrial vehicle driving feeling improvement method, which comprises the steps of respectively processing by taking different acceleration or deceleration dynamic regulation modes of industrial vehicles as division references on the basis of a rotating speed difference delta N obtained by subtracting an instruction rotating speed in an electric industrial vehicle control system from an actual rotating speed obtained by measuring a vehicle movement condition, after the rotating speed difference delta N exceeds a given rotating speed threshold value delta Nref, obtaining an acceleration and deceleration scale factor K through calculation based on the rotating speed difference as input, controlling adjustment of the instruction rotating speed under the acceleration or deceleration working condition by using the acceleration and deceleration scale factor K, and regulating and controlling the advancing speed of the industrial vehicle in the mode that the instruction rotating speed is adjusted to be continuously close to the actual rotating speed.

Description

technical field [0001] The invention relates to the field of new energy industrial vehicles, in particular to a method for improving the driving experience of industrial vehicles. Background technique [0002] Industrial vehicles, especially heavy-duty industrial vehicles that are different from ordinary civilian vehicles, such as cranes, forklifts, excavators, forklifts and other heavy-duty vehicles, when climbing or overloading, one of the ideal requirements is to drive After the driver releases the accelerator, the vehicle should stop as soon as possible to prevent the uncontrolled feeling that the vehicle continues to move forward in a short time. However, due to certain reasons, the vehicle will not be able to stop in time, which will cause the driver to have an abnormal driving feeling that the vehicle is not controlled. This also has a certain impact on the stability control of industrial vehicles. The control effect of conventional industrial vehicles and A large pa...
