Abstract: Disclosed is a throttle quadrant arrangement utilizing a throttle lever mechanically connected to three Rotary Variable Differential Transformers (RVDTs). The signals from the RVDTs are monitored by a process where the processing component. More specifically, RVDT outputs are monitored by the engine control system to determine if they are outside a predetermined range of operability. If an RVDT is not operable, the engine control system establishes a thrust output using the signal from one of the functional two. If only one or none are within the range, the system moves on to a default mode.

Abstract: A vehicle control system comprises: an engine (4); an accelerator position sensor (10) configured to detect the position of an accelerator pedal; a steering device; a PCM (14) configured to generate a deceleration in the vehicle to control the attitude of the vehicle, when a steering angle-related value as a parameter related to a steering angle of the steering device increases; and a brake unit (16) configured to generate a deceleration in the vehicle, independently of reduction of an output torque of the engine, wherein the PCM is configured to generates the deceleration by means of the reduction of the output torque of the engine when a depression of the accelerator pedal is detected by the accelerator position sensor, and to generate the deceleration by the brake unit (16) when the depression of the accelerator pedal is not detected by the accelerator position sensor.

Abstract: A grip, a magnet 140, and a substrate 150 are included. The grip is rotatable between positions where a throttle is fully closed and a position where the throttle is fully open with a rotating shaft as a center. The magnet 140 rotates integrally with the grip. The substrate 150 includes a plurality of Hall elements 165 and 175, and is fixed to face the magnet 140. The plurality of Hall elements 165 and 175 are disposed in such a way that magnetic flux densities different from each other are respectively applied to the plurality of Hall elements 165 and 175 when an external magnetic field acts in a state where the grip is located in the position where the throttle is fully closed.

Abstract: In various aspects, internal combustion engines, engine controllers and methods of controlling engines are described. The engine includes a camshaft and a two cylinder sets. Cylinders in the first are deactivatable and cylinders in the second set may be fired at high or low output levels. The air charge for each fired working cycle is set based on whether a high or low torque output is selected. In some implementations, the camshaft is axially shiftable between first and second positions. First cam lobes are configured to cause their associated cylinders to intake a large air charge during intake strokes that occur when the camshaft is in the first position. Second cam lobes for cylinders in the second set cause their associated cylinders to intake a smaller air charge when the camshaft is in the second position. Second cam lobes for cylinders in the first set deactivate their associated cylinders.

Abstract: Methods and systems are provided for improving fuel economy by opportunistically lowering engine idle speed below a base idle speed when electrical loads are not present. A hydraulic brake pressure is increased when the idle speed is raised, in anticipation of vehicle propulsion. The brake pressure counteracts any creep torque and unintended vehicle acceleration resulting from the rising engine idle speed.

Abstract: A control system and method for a vehicle having a powertrain comprising a torque generating system and an automatic transmission each utilize a pedal position sensor configured to measure a position of an accelerator pedal of the vehicle and a controller configured to, based on the accelerator pedal position, detect a pedal tip-in or tip-out event and, in response to detecting the pedal tip-in or tip-out event: (i) determine a desired output torque for the torque generating system corresponding to the pedal tip-in or tip-out event and (ii) command the torque generating system to gradually transition, over a period, from its current output torque to the desired output torque to mitigate clunk caused by abrupt contact between gear teeth of the torque generating system shaft and the automatic transmission shaft.
