Integrated Estimation of Vehicle States, Tire Forces, and Tire-Road Friction Coefficients |
|
Tesheng Hsiao, Jing-Yuan Lan(National Chiao Tung University, Taiwan), Hanping Yang(Industrial Technology Research Institute, Taiwan) |
| This paper proposes an integrated estimation system that provides accurate estimates of the vehicle/tire/road states from available sensor measurements. More importantly, the tire-road friction coefficient of each tire can be separately estimated. The performance of the proposed estimation system is verified by simulations based on a complex nonlinear vehicle/ tire model. |

A CAN-Based Design for the Control of Electric Vehicle |
|
Der-Cherng Liaw, Cheng-Yu Yu, Kuo-Chen Wu(National Chiao Tung University, Taiwan) |
| A CAN-based event trigger design for vehicle control is proposed in this paper for vehicle control. The proposed design covers the development of CAN communication node, which is developed by using Microchip PIC18F4585 and transceiver MCP2551. An interactive GUI-based utility developer is also built up for user to develop the required function call to cope with the design specification, while a wireless electric-driven control vehicle is served as a platform to verify the design of drive-by-wire and brake-by-wire operations. Experimental results demonstrate the success of the proposed design. |

|
Der-Cherng Liaw, Chia-Wei Yeh, Sung-Ming Lo(National Chiao Tung University, Taiwan) |
| In this paper, we propose another scheme for time division wireless monitoring transmission protocol (TDWMTP). This design is based on IEEE 802.11a standard with the transmission method of TDMA (Time Division Multiple Access) to enhance and implement the function proposed in (Liaw, Wang and Lai, 2013). Experimental results demonstrate the success of the proposed design. |

An Anti-Racing PWM-based Battery Pack Equalization |
|
Lan-Rong Dung(National Chiao Tung University, Taiwan) |
| Following the trend of eco-conscious, the automakers tend to use high-voltage packs in the electric vehicle or hybrid electric vehicle. The packs are formed by battery cells in series and parallel connections. Because of the variation of battery production, their capacity, impedance, lifetime and chemistry characteristic vary with ambient temperature. When the batteries are charged or discharged as a pack, the differences result in the imbalance of the battery voltage. The PWM-based equalization successfully eliminates the racing phenomenon and shortens charging time by 48%. |

A New Method for Three-dimensional Measurement with Two Horizontally-aligned Omni-directional Cameras |
|
Sheng-Fuu Lin, Jau-Chi Ke, Hsin-Yi Liu, Jiao-Rou Liao(National Chiao Tung University, Taiwan) |
| In this paper, a new method for three-dimensional measurement with two horizontally-aligned omni-directional cameras is proposed. Some omni-camera stereo vision systems calculate three-dimensional information which always considers either azimuth angles or elevation angles causing inaccuracy easily. The proposed method takes into account both azimuth angles and elevation angles in order to reduce errors. Besides, the range of interest (ROI) is 3 to 8 meters around cameras in the system. The proposed method has better performance. |
