Software is stored in the two CPUs, the CPU (I) is used for finishing data acquisition and data processing, and the CPU (II) is used for finishing data comparison, alarm and vehicle control. According to the invention, the faults of the vehicle in the running process are detected in aspects of a transmission system, an ignition system, a fuel system, a lubrication system, a power supply system, and the like so as to achieve the aims of in-time detection, alarm and control.
Description
Technical field
The invention belongs to the automobile Control Software, vehicle failure control method particularly is at the fault that occurs in the vehicle traveling process.
Background technology
Vehicle in use, fault that unreasonable operation causes always appears or because the extraneous problems such as fault that change the automobile that causes, and existing vehicle is in good, the supporting vehicle failure control method of a cover not, therefore develops a vehicle failure control method that detects, point out and control of being used to during at running car.
Summary of the invention
The objective of the invention is: provide a vehicle failure control method, the fault that occurs during at running car.
Technical scheme of the present invention is: relate to the vehicle failure control method, its hardware components comprises microcomputer, surface-mounted integrated circuit, the audio control unit that contains two CPU at least and adopts the sensor everywhere of data; Software is stored among two CPU, and CPU I finishes data acquisition and data handing, and CPU II finishes data comparison, warning and automobile control, and it is characterized in that: vehicle failure control method operating procedure is as follows:
In step 1, start a car microcomputer switch on is simultaneously started working, and is installed in automobile sensor everywhere and begins to do data collection task;
In step 2, sensor everywhere transmits the data of gathering, and is divided into analog signal and digital signal two classes by surface-mounted integrated circuit and calculates the signal of function identification and be sent among the CPU I, and CPU I carries out comprehensive computing;
In step 3, CPU I is sent to the data of handling well among the CPU II;
In step 4, CPU II carries out scope relatively with CPU I data A that transmits and the preset data that is stored among the CUP II, and divide four class mode compared result to handle: the first kind, data A in preset range with interior or when exceeding in the preset range 5%, judge that then automobile is working properly, automobile normal running; Second class when data A exceeds preset range 5%-10%, is then judged the running car slight abnormality, and software acoustic control unit starting sends voice suggestion; The 3rd class when data A exceeds preset range 10%-20%, judges that then running car is unusual, software acoustic control unit starting, and prompting gives the alarm; The 4th class, data A exceeds preset range 20% when above, then judges the running car severely subnormal, and software directly acts on the power of vehicle assembly, forces car deceleration or stops to travel;
The continuous image data of sensor everywhere also meets at microcomputer with data and handles, thereby reaches the purpose of Fault Control;
When the vehicle failure control method force automobile to stop to travel or the people when stopping running car, the vehicle failure control method is cut off the power supply and is also closed, and returns to initial condition.
Described vehicle failure control method, its feature are that sensor has driving system sensor, ignition system sensor, fuel system sensors, lubricating system sensor and electric power system sensor respectively.
When described vehicle failure control method, its feature are this software of new car adapted, carry out supporting and debugging; When having used this software of automobile adapted of one section, rationally adjust according to the situation of current automobile.
Characteristics of the present invention are: detect automobile fault in the process of moving from aspects such as driving system, ignition system, fuel system, lubricating system and electric power systems, thereby reach timely the purpose that detects, points out and control.
Description of drawings
The present invention is further illustrated below in conjunction with embodiment.
Fig. 1 is a vehicle failure control method diagram of circuit.
Specific embodiment
Embodiment 1: vehicle failure control method, its hardware components comprise microcomputer, surface-mounted integrated circuit, the audio control unit that contains two CPU at least and adopt the sensor everywhere of data; Software is stored among two CPU, and CPU I finishes data acquisition and data handing, and CPU II finishes data comparison, warning and automobile control, and it is characterized in that: vehicle failure control method operating procedure is as follows:
In step 1, start a car microcomputer switch on is simultaneously started working, and is installed in automobile sensor everywhere and begins to do data collection task;
In step 2, sensor everywhere transmits the data of gathering, and is divided into analog signal and digital signal two classes by surface-mounted integrated circuit and calculates the signal of function identification and be sent among the CPU I, and CPU I carries out comprehensive computing;
In step 3, CPU I is sent to the data of handling well among the CPU II;
In step 4, CPU II carries out scope relatively with CPU I data A that transmits and the preset data that is stored among the CUP II, and divide four class mode compared result to handle: the first kind, data A in preset range with interior or when exceeding in the preset range 5%, judge that then automobile is working properly, automobile normal running; Second class when data A exceeds preset range 5%-10%, is then judged the running car slight abnormality, and software acoustic control unit starting sends voice suggestion; The 3rd class when data A exceeds preset range 10%-20%, judges that then running car is unusual, software acoustic control unit starting, and prompting gives the alarm; The 4th class, data A exceeds preset range 20% when above, then judges the running car severely subnormal, and software directly acts on the power of vehicle assembly, forces car deceleration or stops to travel;
The continuous image data of sensor everywhere also meets at microcomputer with data and handles, thereby reaches the purpose of Fault Control;
When the vehicle failure control method force automobile to stop to travel or the people when stopping running car, the vehicle failure control method is cut off the power supply and is also closed, and returns to initial condition.
Embodiment 2: sensor has driving system sensor, ignition system sensor, fuel system sensors, lubricating system sensor and electric power system sensor respectively as different from Example 1.
During work, for example when galloping, tyre temperature in the driving system, the temperature of driving engine constantly rises, the variation of other system is little, the driving system sensor is sent to surface-mounted integrated circuit with data so, surface-mounted integrated circuit converts temperature information the analog signal of calculating function identification to and is sent to CPU I, total data and output data A to CPU II that CPU I comprehensive sensor is collected, CPU II carries out scope and judges, if in 5% normal range then automobile still can travel according to present speed; If continue to quicken, CPU II will carry out voice suggestion or alarm prompting according to the judgement of data A so, remind chaufeur should reduce moving velocity; If CPU II decision data A exceeded 20% limit range, will directly act on the (PCC) power of automobile so, force car deceleration or only travel.
When this software of new car adapted, should carry out supporting and debugging; And when having used this software of automobile adapted of one section, then should rationally adjust according to the situation of current automobile.
