    摘要:

    為了克服汽車駕駛機(jī)器人在實際車輛上調(diào)試存在的危險以及快速獲得試驗車輛的性能,設(shè)計了汽車駕駛機(jī)器人駕駛性能評價半實物仿真平臺,可以借助這個平臺對駕駛機(jī)器人駕駛車輛的品質(zhì)進(jìn)行性能評價。該平臺中實際車輛由汽車縱向動力學(xué)數(shù)學(xué)模型代替,它可以模擬實際車輛的工作狀態(tài),輸入信號為通過傳感器測得的駕駛機(jī)器人油門機(jī)械腿、制動器機(jī)械腿、離合器機(jī)械腿和換擋機(jī)械手的位移,輸出信號為經(jīng)模型計算得到的發(fā)動機(jī)轉(zhuǎn)速和車速,駕駛機(jī)器人不用做任何改動就可在該平臺上進(jìn)行駕駛操作。仿真和實車試驗結(jié)果驗證了該平臺的有效性。

    Abstract:

    In order to overcome the danger existed in the debugging of vehicle robot driver in actual vehicle and quickly obtain the performance of test vehicle, a semi-physical simulation platform for driving performance evaluation of robot driver was designed. The performance evaluation of robot driver could also be conducted by the simulation platform. In the platform, the actual vehicle was replaced by the vehicle longitudinal dynamics model, and it could simulate the working conditions of actual vehicles. The displacement of throttle pedal, brake pedal, clutch pedal, and shift manipulator for vehicle robot driver measured by the sensor was used as input of the platform, and vehicle speed and engine speed calculated by the model were used as output of the platform. Vehicle robot driver could operate the platform without any changes. Simulation and real vehicle test results showed the proposed platform was effective.
