8 microprocessors (cpus) were used to achieve system control in dejiro's smart electric vehicle. An on-line and gravity sensor for sensitive humans is equipped to complement smart load detection techniques. Dejiro's smart electric car scans the driver's posture changes and physical position at a speed of 500 times/s, and the speed of the scan allows the driver to experience driving pleasure. Dejiro's smart electric vehicle is designed in such a way as to be light and easy to carry, save space, do not occupy parking spaces and any public space, project the size of 9kg and the size of a4 paper in the car, and carry public transport such as subways and public transport. Dejiro's smart electric car is free and flexible, has a zero-turn radius, achieves a back-to-back turn, and comes and goes at any time without worrying about the narrowness of space. The ability to climb a slope can be stopped at any time on a steep slope of 15° without an earlier acceleration. Dejiro's smart electric vehicle is driven by a cycled, continuous power source, which allows you to replenish it with new energy at all times at your convenience, with a single charge of up to 26 to 40 kilometres per hour. Dejiro's smart electric vehicle, with zero emissions and no contamination, fits green, environmentally friendly, energy-efficient, intelligent, and so on in its twenty-first century mobility equipment. Teichiro's smart electric vehicles, gps and gsm communications technology, achieves a mia-class stand-by, mobile phone positioning through mobile phone app applications, electronic fencing, track queries, crash alarms, remote maintenance, etc. Dejiro's smart electric vehicle locates and each deichiro's locator is equipped with a coded control key. The control key was coded using 128-digit encrypted programming techniques, and a dejiro key was matched to a security guard. Dejiro's smart electric car enters the system in a security lock mode by controlling the key, and if someone moves the body, the body shakes and the tire locks. The built-in carlog (commonly known as the black box) enables the preservation of first 3s and second 1s data in case of malfunction. If i-robot is found to be missing, it is only necessary to log into our gps platform with a mobile phone or computer, so that the vehicle can be quickly located and it can be remotely controlled and locked。
