“Simulation has enabled KSR engineers to optimize inductance sensor designs prior to building a prototype. The new approach substantially reduces the time required to engineer its products to fit customer applications. The net result is a substantial decrease in engineering costs and a reduction in time to market.”

An electronic throttle control works behind the scenes to remove the mechanical link between the automobile accelerator and throttle, and instead controls the throttle with an electric motor. An electronic control unit (ECU) determines the correct throttle position based on data collected from two automotive sensors that track the position of the gas pedal. The motor that controls the throttle is then driven to the required position via closed-loop control from the ECU.
Most inductance sensor applications can be addressed by a common design; however, as KSR expands the technology to different applications with different sensing ranges and packages, a custom design is required. Trial and error takes approximately three months to develop custom inductance sensor designs. The company needed to reduce development time, and therefore, costs and time to market.
