RESEARCH IN AUTOMOTIVE VEHICLE CONTROL BY USING GPS

Abstract

Many types of vehicle control systems can be developed to help drivers maintain stability, avoid clutter, or customize the features to handle. However, lack of information and parameters, which is a major obstacle. To solve these problems presented by the method of estimating the status and parameters using the Global Positioning System (GPS) to control the driving dynamics. Start by explaining the basic motor models commonly used to drive car dynamics. This is a method of estimating the main vehicle statuses - flip angle, vertical velocity, rotation speed by combining auto inertia sensor with GPS receiver. Then dynamics simulations are independent of vehicle parameters after integrating inertial sensors with GPS to provide data and high levels of updating of sensor states. With a two-antenna GPS system, these measurements can be quantified by measurements and proved to be important in estimating the side angles of the vehicle. Using the same GPS system, a new method of compensating for wavelengths and gradients has been developed to improve state accuracy and estimate the deviation of the sensors. In addition, sensitivity-correction methods as well as coupling devices of inertial sensors are provided to reduce the measurement error.
