Title: Innovations by John T La Belle
Introduction
John T La Belle is a notable inventor based in Long Beach, California. He has made significant contributions to the field of automotive testing technology. With a total of 6 patents to his name, La Belle's work focuses on improving the methods and apparatuses used for testing motor vehicles.
Latest Patents
One of his latest patents is a method and apparatus for testing motor vehicles under simulated road conditions. This innovative chassis dynamometer includes at least one roll that engages the driven wheel of a motor vehicle, along with a power supplying and/or absorbing unit (PAU) coupled to the roll. Speed and force sensors are integrated to provide signals that represent the roll speed and the force supplied to or received from the roll. The system also generates vehicle inertia, road load, and parasitic loss signals, which are crucial for accurate testing. A processing unit calculates a velocity error signal based on these inputs, allowing for precise control of the PAU.
Another significant patent by La Belle is a dynamometer designed for simulating vehicle road load and/or inertial forces. This dynamometer utilizes an induction motor that is directly coupled to the vehicle engine or driven wheels. A computer processes the engine or wheel speed and torque to provide a desired torque signal to a motor power controller. This setup effectively simulates the road load and inertial forces encountered during actual vehicle operation, while also compensating for parasitic losses.
