Description of the invention: [Technical field of the invention] The power supply of the computer system for the vehicle of the invention effectively reduces the power meter system of the vehicle when the vehicle is parked = the type is powerful, and can be automatically activated at the start of each system, =_ Unnecessary electricity: taking into account the reliability of the car _ system and safety ====, and effectively save car power. Source S, the method can be [previous technology]? The technology of the car industry is advancing by leaps and bounds, and the products are refurbished. Among them, the computer products are inside or outside the car, or the driver and passengers are: the car is increased. Products, power supply is not easy to get, most of the commissions say that 'the supplier of the car is constantly rushing toward the low power loss or the PDA to share the confession of the ambitions, such as the hands of different 様Μιτ Γ & mobile phone 'the system is based on the various system of the Wei system in the various (four) bottom ^, when Lin = low energy-consuming state, that is, when 1 does not hit Feng..., two j壬 standby or dormant use, 1 power, mobile phone or mobile phone or network feeding device is not hired; cost, efficiency, volume and many other factors, can save power, and extend life. However, it is equipped with the navigation system of Xiangdian _ _ _ _ _ _ _ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ Find a better way. Moreover, since the power source of the vehicle and the electronic equipment of the previous 1267733 is the power of the battery or generator of the vehicle, the voltage and current changes are larger than those of the general power supply, so the power management of the vehicle electronic equipment is made. The system must also strengthen the security protection function to prevent electronic devices such as car computers and GpS from being damaged due to abnormal power changes. In view of the above-mentioned lack of use, the inventor has invented a power management method for a computer system for vehicles, which has been used for many years. / It includes - vehicle computer system 'The vehicle computer system has a navigation tiir micro control touch, _ the micro control side off to control the navigation system in the positive suspension type _ _ _ _ _ _ _ _ _ _ _ _ _ The function of consuming power; when it is unable to switch its working mode normally, the micro-control benefits will be based on the limit of the slaves, and the source mode, and the yarn has no effect on the safety and reliability of the device. Old, [Summary] The related invention is related to the above object and other simple descriptions, so that the review committee is easy; solution: better specific 1267733 / power management method of the vehicle brain of the present invention, including - vehicle computer 1 'The phase of the age of the system - navigation button 2, - microcontroller 3 ^ a power system 4, _ microcontroller to enable navigation to switch between the normal mode and the sleep mode, to achieve power savings The purpose will be explained in detail. Figure 2 to the 4 county's financial management system and the flow chart of the service example. Due to the limitation of the power source on the vehicle, this i is suitable for effectively reducing the number of drivers in the parking lot. Power consumption, = the main method is the profit controller 3 to control the cake navigation system 2 in the positive mode sleep mode three power working mode to switch,
