Mathematical calculation-based driving simulation control
An example of achieving the reproduction of actual vehicle driving torque in powertrain evaluation through mathematical operation control.
At the testing site for drive-related components, when conducting simulations, we assign computational elements such as air resistance, rolling resistance, gradient resistance, and acceleration/deceleration resistance, along with site-specific testing specifications and coefficients, to calculation formulas to derive load torque. However, the existing methods were insufficient to accurately reproduce the load torque generated during actual vehicle operation in response to changes in vehicle models and testing content, necessitating the flexible addition, modification, and deletion of elements, coefficients, and calculation formulas. Integrated computation of physical parameters according to acceleration and deceleration states At Seagull Co., Ltd., we adopted a method that allows for the flexible addition, modification, and deletion of calculation formulas and necessary physical parameters for accurately reproducing load torque for each driving state, such as vehicle models and acceleration/deceleration. Specifically, parameters such as rotational speed (rpm), incline angle (°), gravitational acceleration (m/s²), vehicle weight (kg), tire radius (m), reduction ratio, inertia (kg·m²), and coefficients, along with calculation formulas corresponding to the states during acceleration and deceleration, are set for each vehicle model. The load torque is output to the testing machine through real-time computational processing in milliseconds by the CPU and FPGA of the embedded unit.
