If the engine speed follows an invariable small reference during the vehicle start-up process, the driver can gain the optimum objectives of small wear loss and comfort by operating the accelerator according to his intent. But the torque generated by the engine cannot overcome the gravitation if the reference speed is very small while the vehicle starts up on the hill. In order to solve this problem, an accelerometer is used to measure the grade of the hill. According to this measured grade, the reference engine speed is determined using a fuzzy inference mechanism. A hilling start-up control system is established based on this technology and variable structure cascade double loop control algorithm.
