| 抄録（英） | Recently, off-road four-wheelers are used in various situation. To develop future models that matches the users’ demands, collecting data about how vehicles are actually used in market is effective. In this paper, we proposed a method to estimate tire forces using formula derived from simple equation of motion of a vehicle. This method is constructed to be suitable for mass-produces vehicles, since only inexpensive sensors are needed. In order to verify the estimation accuracy of the proposed method, another method that can measure the tire forces more directly and to be compared with the proposed method is necessary. In research and development in the field of automobiles running on the paved surfaces, tire force is often measured using a six-component force sensors mounted on the wheels. However, these sensors are basically intended for vehicles driving on the paved surfaces, and are not considered for measurement in situations such as unpaved off-road surfaces. Therefore, we applied another method to calculate the tire force based on the measurement results of strain gage attached on vehicle frame. Strain values are pre-calibrated by simulation and driving tests of basic driving patterns. The estimated tire forces by the proposed methods are compared with those calculated by strain gages measurement of vehicle frame, and the good agreement has been obtained. 翻訳 |
