Anti-slope-slipping driving controller, control system and control method of automobile

Abstract

The invention relates to an anti-slope-slipping driving controller of an automobile. The driving controller comprises a slipping position detection module, a speed control module and a feedback output module, wherein the slipping position detection module is used for judging whether the automobile is in a slipping position state or not, the speed control module is used for generating a given rotating speed omega[r]<*> and a given value i[d]<*> of an exciting current and generating a given value i[q]<*> of a torque current according to the given rotating speed omega[r]<*>, and the feedback output module is used for generating a torque voltage signal u[q]<*> and an exciting voltage signal u[d]<*> according to the given value i[q]<*> of the torque current and the given value i[d]<*> of the exciting current respectively and outputting the values to a three-phase inverter so that a motor can be driven to operate. The invention further provides an anti-slope-slipping driving control system and method of the automobile. According to the driving controller and the control system and method, an anti-slope-slipping mode is started by judging and detecting whether the automobile is in a slipping position state or not, the adaptability of the anti-slope-slipping control system is effectively improved, and the timeliness is improved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and more specifically, relates to a vehicle slope prevention drive controller, system and drive control method. Background technique [0002] With the development of social economy, automobile has become one of the indispensable tools in people's life, and the automobile industry has become the pillar industry of modern economy. However, the development of automobiles is inseparable from the limited energy on the earth. With the development of the automobile industry, energy consumption continues to increase, and the energy crisis is becoming more and more serious. At the same time, the environmental pollution caused by the use of energy is becoming more and more serious. Electric vehicles have the characteristics of low pollution, low noise, energy saving, simple structure, control and maintenance, etc., and are an effective way to solve environmental and energy problems.

Problems solved by technology

[0004] In the above anti-slope control technology, the vehicle controller uses the estimated slope and resistance to estimate the torque when calculating, and the estimated data has poor adaptability and accuracy; and there is a certain degree of delay between each step, for example, The delay time for the encoder signal of S1 to start the sensor for data collection can be set to T1, similarly, the delay between S2-S3 is T2, the delay between S3-S4 is T3, and the delay between S4-S5 The delay is T4, so the overall possible delay is T1+T2+T3+T4, so the existing anti-slope control technology has poor timeliness and cannot achieve a good anti-slope effect

[0005] Based on the defects of poor adaptability, low accuracy and poor timeliness of the above-mentioned anti-slope control technology, existing vehicles lack the defects of effective anti-slope technology, so the drive controller and drive control system of the vehicle need to be improved
