A new energy vehicle safety control system

Abstract

The invention relates to the technical field of vehicle control systems, in particular to a new energy vehicle safety control system. The new energy vehicle safety control system comprises an accelerator data acquisition module, a vehicle speed acquisition module, a mode control module, a gear position detection module and a vehicle speed control module. The accelerator data acquisition module isused for acquiring the depth of a user pressing an accelerator, the vehicle speed acquisition module is used for detecting a current vehicle speed, the gear position detection module is used for detecting a current gear position, and the mode control module is used for controlling an operation mode of a vehicle according to the current gear position. The operation mode includes a normal mode, a limiting mode and a simulation mode, and the vehicle speed control module is used for controlling a maximum speed, a maximum torque and traction force of the vehicle in the limiting mode. According to the new energy vehicle safety control system, the new energy vehicle can simulate a traditional vehicle, so that students can master the control mode of the traditional vehicle, the students drive thetraditional vehicle conveniently, danger is avoided, and the safety of the students and the vehicle is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile control systems, in particular to a new energy automobile safety control system. Background technique [0002] With the development of science and technology and the deepening of the concept of environmental protection, new energy vehicles, especially pure electric vehicles, have gradually become the main direction of future automobile development. [0003] Because the characteristic of driving school vehicles is to run in a certain area and do not need to run long distances, electric vehicles are very suitable for driving school learning vehicles, which can not only save a lot of fuel, save energy and protect the environment, but also do not need to go to gas stations , It can be charged as needed, directly in the internal venue of the driving school, which can effectively reduce the operating and management costs of the driving school. [0004] However, since the electric vehicle is driven b...

[0004] However, since the electric vehicle is driven by a motor, the characteristics of the motor are quite different from the engine of a traditional car. Taking the start of a car as an example, the characteristic of a traditional fuel-powered vehicle is that the engine starts at an idle speed of 800-1500 rpm. In stable operation for one end of the time, the clutch shift mechanism can be used to output power to the gearbox, while the rotation of the motor of the existing electric vehicle is adjusted by the controller and the pedal governor, and its rotation starts from zero. Yes, there is no idling state, and the electric vehicle motor accelerates quickly, and the sudden acceleration of the vehicle after stepping on the pedal makes people feel more radical and abrupt

On the one hand, because the students are all newbies, they are not familiar with the vehicle, and they have no driving experience themselves, too fast speed-up will easily cause safety problems, ranging from damage to the vehicle or driving school facilities, and seriously affecting the safety of the students; on the other hand, in the In the driver's license test, many subjects need to use the clutch gear, start and stop with the brakes, and especially require the use of the semi-linkage state of the clutch to start and stop slowly. State complete, this EV has the potential to affect cadets' exams
