control the forward speed of the vehicle in response to signals received from sensors mounted on the pavement surfacing machine a flowchart illustrating a process for generating control signals in response to inputs from an electronic control module 44 load cells 46 and a rotary transducer 48 in accordance with the present invention is illustrated in fig3 the process 68 involves determining 70 the vehicle speed using inputs from the rotary transducer once the speed is determined it is compared 72 to a preselected maximum allowable vehicle speed if the pavement surfacing machine exceeds the specified allowable maximum speed then the control system 18 outputs 74 a signal to the hydraulic pump which reduces the speed of the pavement surfacing machine if the vehicle speed is below the specified maximum allowable speed then the power output of the grinding engine 30 is measured 76 by examining the input received from the electronic control module 44 a decision 78 as to whether the power output of the grinding engine exceeds the specified maximum allowable power output is then performed if the measured power output of the grinding engine exceeds the specified maximum allowable power output then the controller 40 sends 80.
