Abstract: The present disclosure relates to a connector using a ball and a detent and, more particularly, to a connector in a clutch connection structure used in an electrical automobile, which includes: a locking part formed at a body; a latch in contact with the locking part; a first solenoid driving part disposed on one side of the latch; and a second solenoid driving part disposed on the other side of the latch, in which the first solenoid driving part and the second solenoid driving part face each other with the latch being interposed therebetween, such that an operation of a clutch when the clutch operates becomes simple, and thus, noise, vibrations, and durability thereof are improved.
Abstract: An energy module determines an amount of energy consumed by an electric heater of a fuel vapor canister since an ignition system of the vehicle was last transitioned from OFF to ON. A purge valve control module controls opening a purge valve while the ignition system of the vehicle is ON, wherein fuel vapor flows from the vapor canister through the purge valve to an air intake system when the purge valve is open. A heater control module selectively applies power to the electric heater of the fuel vapor canister and, based on at least one of the amount of energy consumed by the electric heater and a mass of fuel vapor that has flowed through the purge valve, selectively disconnects the electric heater from the power until after the ignition system is transitioned from ON to OFF.

Abstract: A fuel control system according to the principles of the present disclosure includes a parameter determination module, a parameter learning module, and an injector driver module. The parameter determination module determines a parameter of a fuel injector in an engine at an operating condition of the engine. The parameter learning module identifies index values in a table based on the engine operating condition and adjusts learned values of the fuel injector parameter corresponding to the index values based on the determined value of the fuel injector parameter. The injector driver module selectively applies power to the fuel injector based on the learned values.
Abstract: A set-up stand is provided including a counterbalance mechanism for use in reconfiguring an end-effector with an articulating portion rotated by a bi-directional rotary locking device, for example, a clutch. A counterbalance mechanism is provided including a holding member which is attached to a preloaded member and connected to an articulating portion of the end-effector during reconfiguration of the end-effector. The preloaded member provides a tension load to counterbalance the gravity moment load of the articulating portion when the articulated portion is rotated in the same direction as the output shaft of the bi-direction rotary locking device, to prevent overhauling, chattering or binding stops during rotation and reconfiguration. A method is provided to utilize the counterbalance mechanism as described.
Abstract: A communication system and method utilizing the communication system. The method includes performing a vehicle function based on a proximity of two wireless devices to a vehicle. The steps of method include: establishing a short-range wireless communication (SRWC) link between a SRWC system on the vehicle and a first wireless device; establishing another SRWC link between the SRWC system and a second wireless device, wherein the first and second wireless devices are associated with a common user; receiving a wireless signal at the SRWC system from each of the first and second wireless devices; determining a proximity of the two wireless devices based on receiving the wireless signals; and performing a vehicle function based on the determined location.

Abstract: A park gear and pawl assembly for a vehicle transmission includes a park gear, a hydraulic control passage, a park pawl, a hydraulic pump, an abutment assembly, a park rod, and a hydraulic actuator. The park gear is fixed for common rotation to an output shaft of the transmission. The hydraulic passage is integrated into a housing of the transmission. The park pawl is engaged with the park gear when the park pawl is in a first position. The hydraulic pump includes an input member and output port. The input member is drivingly connected to the output shaft of the transmission and the output port is in communication with the hydraulic. The park rod at least partially disposed in the abutment assembly. The hydraulic actuator axially actuated via hydraulic fluid pressure in the hydraulic passage.
Abstract: A fuel control system includes a target rail pressure module. The target rail pressure module determines a target fuel rail pressure of a fuel rail of a direct injection engine. An offset module determines an offset value based on an engine speed of the direct injection engine and at least one of an engine load and an air per cylinder. A modifier module determines a modifier value based on a temperature of the direct injection engine. A rail pressure control module adjusts a current fuel rail pressure of the fuel rail based on the target fuel rail pressure, the offset value and the modifier value.

Abstract: A system in a vehicle including at least one sound quality valve arranged in an exhaust system of the vehicle includes a sound quality valve control module that determines whether one or more criteria for opening the sound quality valve are met, selectively actuates the sound quality valve to an open position if the one or more criteria for opening the sound quality valve are met, and maintains the sound quality valve in a closed position if a required one of the one or more criteria for opening the sound quality valve is not met. A downshift detection module determines whether aggressive driving behavior is detected. If the aggressive driving behavior is detected, the sound quality valve control module actuates the sound quality valve to the open position regardless of whether the required one of the one or more criteria for opening the sound quality valve is met.

Abstract: An air-delivery system, for use in a vehicle. The system includes a backrest of a vehicle seat assembly and an air-delivery port connected to or integral to the backrest. The system also includes an input conduit connected to the air-delivery port for delivering air received from an air source to the air-delivery port. The air-delivery port is configured and arranged in the backrest facing a generally aft direction to, during operation of the system, deliver air received from the air source aftward from the backrest.
Abstract: A method of managing an operating state of an electrified powertrain includes a controller identifying a plurality of available operating regions defined by at least one available operating state of the powertrain, each operating region representing a distinct range of operating conditions. The available operating regions include an avoidance region defining a plurality of unwanted operating conditions and separating a first allowable operating region from a second allowable operating region such that the first and second allowable operating regions are noncontiguous. The method identifies at least one ideal operating condition in each of the available operating regions, determines a preferability factor and stabilization factor for each of a current and each of the ideal operating conditions, and arbitrates the factors to identify one of the current and ideal operating conditions as an optimized operating condition to produce a required parameter value.

Abstract: Method and system for producing a part using die casting or injection molding with a top die and undercut dies that are independently moveable from the top die. In one particular form, the method and system can include a top die and one or more undercut dies that can have a protrusion. The undercut dies can be lowered into a base of the system and moved away from each other, and the top die can be lowered into a receiving portion between the undercut dies. A molten liquid can be introduced into a space between the undercut dies and additional aspects of the system, and after cooling to form a part, the top die can be moved vertically to allow space for the undercut dies to be moved toward each other. The undercut dies can be moved vertically and the part can be removed.

Abstract: A press-hardened steel component and a method of producing the same. In one form, a workpiece that will be formed into the component includes a coating that is pre-diffused with metal from the workpiece substrate. Examples of such protective coatings may include aluminum-based coatings, as well as from aluminum and silicon combinations. The pre-diffusion of the workpiece permits it to be subjected to the high heating rate of a subsequent press hardening operation without causing localized melting or vaporization of the protective coating.
