Nicely Nonlinear Engine Torque Estimator
In automotive powertrain control strategy, engine torque estimators are preferred to expensive sensors for obvious economic reasons. In the literature several works have been presented proposing both instantaneous engine torque and mean engine torque estimators. The first ones are based on complex models and tipically are suitable for diagnosis purposes, while the latter estimate the torque by ...
متن کاملOperant Learning of Drosophila at the Torque Meter
For experiments at the torque meter, flies are kept on standard fly medium at 25 degrees C and 60% humidity with a 12hr light/12hr dark regime. A standardized breeding regime assures proper larval density and age-matched cohorts. Cold-anesthetized flies are glued with head and thorax to a triangle-shaped hook the day before the experiment. Attached to the torque meter via a clamp, the fly's int...
متن کاملEngine Testing Engine Test System
Engine testing involves measurement of rotating speed and torque of the engine by applying load controlled by a dynamometer connected to its output shaft. HORIBA has developed various types of dynamometer for the purpose of engine testing. They are mainly classifi ed into two types; one is absorbing only dynamometer such as hydraulic dynamometers and eddy-current dynamometers, the other is abso...
متن کاملRemotely detected vehicle mass from engine torque-induced frame twisting
Determining the mass of a vehicle from ground-based passive sensor data is important for many traffic safety requirements. This work presents a method for calculating the mass of a vehicle using ground-based video and acoustic measurements. By assuming that no energy is lost in the conversion, the mass of a vehicle can be calculated from the rotational energy generated by the vehicle’s engine a...
متن کاملEstimation of Indicated– and Load– Torque from Engine Speed Variations
The importance of control systems and diagnostics in vehicles are increasing and has resulted in several newmethods to calculate better control signals. The performance can be increased by calculating these signals close to optimum, but that also require more and precise information regarding the system. One of the wanted control signals are the crankshaft torque and the thesis presents two dif...
