A method of developing a road conditioning monitoring model is disclosed. The method comprises utilizing vehicle sensors to collect data under controlled conditions over a road surface to develop a training data set. The training data set undergoes a data analysis to determine an absolute running mean associated with the first road surface under controlled conditions. Abnormalities in the road surface are detected by comparing the absolute running mean with the training data set. The detected abnormalities are classified to create road surface classification rules. A method of developing a road condition database is also disclosed, that comprises utilizing vehicle sensors during operation of a vehicle to collect data during the operation and feeding the data into the road conditioning monitoring model to classify the road conditions on which the vehicle is driven. A system for determining road condition impact on a vehicle is also disclosed.

Method of determining parameters of interaction between a vehicle and a road

Systems and methods are provided for generating data for sensor system validation. A representative vehicle is equipped with a set of sensors positioned to provide a collective field of view defining a set of sensor locations as a set of master data and encompassing a field of view of a sensor positioned at any of the set of sensor locations. The set of sensor locations includes a sensor location at which no sensor of the set of sensors is placed. The representative vehicle is driven for a distance required for validation of a sensor system to provide master data representing the entire distance required for validation.

Sensor performance validation in advanced driver-assistance system verification

A method of communicating with a vehicle repair facility includes a server receiving from a vehicle an indication that the vehicle requires repair and receiving from the vehicle communication regarding a vehicle location. The server determines a vehicle repair facility as corresponding to the vehicle location and determines contact information for the vehicle repair facility. The server then contacts the vehicle repair facility via the contact information with a message regarding repairs required for the vehicle, wherein the message includes a request for confirmation from the vehicle repair facility to verify use of authentic parts for the repairs required for the vehicle. The server can also determine user contact information for the registered user of the vehicle, and contact the registered user with a message regarding repairs required for the vehicle and a request for the user to verify use of authentic parts for the repairs required for the vehicle.

System and method for communicating with a vehicle repair facility or a user of a vehicle regarding approved parts

A vehicle function switch and a controller electrically are connected together. The controller has a passive mode of operation in which the controller is not responsive to activation of the vehicle function switch to transmit a vehicle function signal. The controller also has an active mode of operation in which the controller is responsive to activation of the vehicle function switch to transmit a vehicle function signal. A mode switch is associated with the controller and adapted to cause the controller to change from the passive mode of operation to the active mode of operation.

Portable remote transmitter to remotely control a vehicle function

A remote control system for a vehicle. The system has a fob with a microphone for receiving audible commands and a radio frequency transmitter for transmitting the commands at a radio frequency via a fob antenna. A receiver for positioning in the vehicle has an antenna for receiving the commands at the radio frequency, a demodulator for recovering the commands, a processor for decoding the recovered commands according to vehicle configuration information, and a network interface for controlling a vehicle system in accordance with the recovered commands and the vehicle configuration information.

A seal within the filler neck of a fluid reservoir is configured to provide fluid channels into the reservior while in the at-rest position, but seals the filler neck when deformed by an externally directed insert in the filler neck. The seal is a hollow bulb with a frusto-conical surface spaced from a parallel frusto-conical surface of the filler neck by a plurality of ribs therebetween. The gap between the ribs, and between the surfaces of the seal and the filler neck, from fluid channels for replenishing the reservoir. A plunger inserted into the filler neck deflects the seal outwardly into contact with the filler neck, closing the fluid channels and preventing matter from entering the fluid reservoir.

Capless fluid reservoir

A checkstrap assembly is provided for a door of a vehicle. The checkstrap assembly includes an arm passing inside a channel. The arm has a first end rotatably mounted to the vehicle frame such that the door may be selectively moved relative to the arm. A roller is rotatably mounted on a second end of the arm and is received in the channel. A wedging device is disposed in the channel in association with the roller. The wedging device and roller engage one another under low boards to provide a locked condition at an infinite number of positions within the channel, and which can be overcome by application of a larger load.

Door check mechanism providing an infinite number of stable positions

A variable length shaft is provided including a housing defining an internal space. A shaft is connected to a plunger device disposed in said internal space. The internal space is filled with magneto-rheological fluid which is selectively provided with a magnetic field for solidifying the fluid to prevent movement of the plunger within the internal space. When the magnetic field is removed, the plunger device moves freely for allowing variation in the length of the variable length shaft system.

Variable length shaft and method for making the same

A method and apparatus for coupling the rotational output member of a first power source to the rotational output member of a second power source. The method controls the acceleration of the output member of the first power source until its rotational speed is equal to the rotational speed of the output member of the second power source. Thereafter, the output members are coupled and the first and second power sources are controlled such that their torque contributions are maintained at a predetermined ratio.

Method and apparatus for coupling the output members of multiple power sources

A vehicle door check assembly is provided including a roller in rolling engagement with an arm. The roller cooperatively engages the arm such that an elastically deformable material is encountered at the roller arm interface providing the vehicle door with an infinite number of secure resting positions between fully closed and fully open conditions.

A vehicle door checkstrap assembly is provided including an arm having the first end engaged to the frame and a second end interconnected to a brake member within the vehicle door. The brake member cooperates with a carriage assembly which slidably engages a guide track incorporated in the vehicle door. A load is exerted from the brake member toward a support face within the door which creates a braking force when the door is in a static state. When the door is moved, the opening force is capable of overcoming the friction between the brake member roller and the supporting face allowing free motion of the door along the guide path. The roller carriage assembly operates such that the door can be located securely in an infinite number of positions between fully open and closed.
