An electric coach and its control method

Abstract

The invention relates to a field exercise driver-training car and a control method thereof. The field exercise driver-training car comprises a battery, an ignition key, an accelerator, a motor controller, a motor and a position sensor. The motor controller comprises a signal collecting module, a control module and a power module, wherein the control module comprises an idling control module and a misfire diagnosis module. Through advanced algorithms inside the motor controller, the field exercise driver-training car can simulate various working conditions of a traditional driver-training car and particularly can achieve idling control and misfire diagnosis, can determine possible misfire causes according to information status and can achieve an idling function by additionally adding a shift simulator; the electric driver-training can stall due to poor cooperation of a clutch and the accelerator during gear shifting, on-shift ignition and hill start and accordingly can omit collection of information of a clutch pedal, a brake pedal and a hand brake as well as omit elements such as a flameout diagnosis circuit and an idling module. The field exercise driver-training car is high in security and can limit the maximum driving speed of the whole car according to actual requirements and obtain thorough fault diagnosis functions.

Description

technical field [0001] The invention relates to a coach car for learning to drive, in particular to an electric coach car for field practice and a control method thereof. Background technique [0002] In recent years, the number of domestic automobiles has increased year by year, and the number of automobiles has exceeded 100 million; the training industry has also increased. According to statistics, by the end of 2012, there were 10,347 driver training institutions nationwide, with 377,000 coaches and 439,000 coaches. There were more than 500 medium- and large-scale driving schools, with more than 1,000 coaches in large-scale driving schools and more than 10,000 trainees. People, still can't satisfy the current upsurge of learning to drive. [0003] But at the same time, the rapid development of the driving school industry has brought great problems. In the current training process, more than 70% of the time for driving school coach cars is used for on-site training. The ...

AI Technical Summary

Problems solved by technology

Its disadvantage is that when the clutch pedal is quickly lifted, the motor is controlled to stop running, which is inconsistent with the actual working conditions of the engine; the idle speed stabilization and acceleration control unit are realized through complex circuits, the system is complicated and the reliability is low

[0030] To sum up, in the existing electric trainer vehicles, there is a large difference in driving feeling from ordinary cars, complex structure, and low reliability. Therefore, there is an urgent need for a design that is reasonable, high The function of the car, the electric coach car with the same driving feeling as a normal car
