throttle body assembly and method for selection of remedial measures in an electronic a throttle control system

摘要

throttle body assembly, comprising:a throttle valve actuator;an input circuit, which receives sensor signals, wherein the input circuit comprises:a first reference voltage; anda second reference voltage; anda third reference voltage;a first throttle flap position sensor (tpa), which is connected with the second reference voltage;a second tpa, which is connected with the second reference voltage;a -manifold absolute pressure sensor (map - sensor), which is connected with the first reference voltage;a manifold air-flow sensor (maf sensor), which is connected with the third reference voltage; anda processor which is connected to the input circuit and to the throttle valve actuator, which sends a control signal on the sensor signals is based, wherein the control signal a remedial measure relates to, wherein the processor comprises a look-up table with remedial measures, which consists of a limited throttle authorization or a switched-off throttle valve or no remedial measure are selected, wherein remedial measures on a failure of the first order and / or a failure of the second order of the first tpa, of the second tpa, of the map-sensor, of the maf sensor, the first reference voltage or the second reference voltage are based, wherein the remedial measure on the basis of the received sensor signals from the look-up table is determined from remedial measures.
