Automobile domain control system, accelerator braking device and braking method

Abstract

The invention discloses an automobile domain control system, an accelerator braking device and a braking method. The automobile domain control system comprises an operation acquisition module, an energy management module, a driving management module and an auxiliary driving module, the accelerator braking device comprises a pedal, the pedal is fixedly connected with a connecting rod and connectedwith an accelerator, a fixed sliding rail is fixedly connected to an automobile body of the automobile, the top end of the connecting rod is connected with the fixed sliding rail in a sliding mode, and the top end of the connecting rod is further connected with a second stay wire displacement sensor which is connected with a domain controller. The second stay wire displacement sensor is used for controlling the start and stop of the accelerator; a headlamp part of the automobile is fixedly connected with a distance sensor, and the distance sensor is connected with the domain controller; and the middle of the connecting rod is connected with an automobile body. The domain controller is a highly integrated domain controller with more optimized performance and higher resource utilization rate, the accelerator and the brake are linked in emergency, and driving safety is guaranteed.

Description

Technical field[0001]The present invention relates to the field of smart cars, in particular to the technical field of safety of pure electric cars, and in particular to an automotive domain control system, a throttle brake device and a braking method.Background technique[0002]In recent years, electric vehicles have become more and more common as a new means of transportation, the popularity of electric vehicles is increasing, and the technologies involved in the development and manufacturing of electric vehicles are also constantly improving. Electric vehicles need to have vehicle control, battery pack management and motor drive functions. The vehicle domain controller implements many complex functions such as vehicle control, accessory management, energy management, and network management. The domain controller masters the most important information of the vehicle and is the core component of the vehicle. The main control chip of the domain controller is a high-speed control chip ...

AI Technical Summary

Problems solved by technology

In reality, real-vehicle road tests are mainly used to detect domain controllers. However, real-vehicle road tests require high manpower, money, and time costs. It is very difficult to build and modify the test environment, and the repeatability is poor.

However, the existing automotive domain control system is used for detection, which mainly uses the switch signal generated by the test board to detect the function of the controller. to test

Therefore, the existing automotive domain control system cannot meet the test requirements of real-time performance and intelligent performance

[0004] With the continuous development of society, the number of cars in our country continues to increase, and more and more people drive, but everyone's driving skills are also very different, even drivers with good driving skills and the state of mind when they encounter accidents are different. Similarly, every year in an emergency, the gas pedal is mistakenly stepped on as a brake, causing personal injury and serious economic losses at the same time.

[0005] Patent No. 201510424031.4 proposes a device and method for remediating the wrong step on the accelerator of an intelligent car. This invention proposes to input the parameters of the accelerator pedal of the individual in advance to distinguish whether the wrong step on the accelerator occurs. It is effective to judge that the accelerator is stepped on by mistake, but in real life, a car is often not driven by a driver, so when changing the driver, it is necessary to change its built-in parameters, which invisibly increases the cumbersome operation and has The risk of forgetting to change parameters

[0006] At the same time, the driver is overtaking at high speed, going uphill, or starting at a red light. Under such circumstances, some drivers like to step on the accelerator very quickly and deeply. It is the accidental stepping on the accelerator, and the current method of identifying the wrong stepping on the accelerator is not accurate

Therefore, not all stepping on the accelerator by mistake, especially when the driver is overtaking at high speed, if the system judges that the accelerator is stepping on the accelerator by mistake and brakes the vehicle, new safety accidents will often occur.
