  • Patent number: 8954218
    Abstract: A vehicle system providing a temporary validation authorization request for one or more processors configured to transmit a signal from the vehicle system to a server once the one or more processors are installed in the vehicle. Once the server receives the installation signal, the processor may receive an in-vehicle authorization message from the server. The in-vehicle authorization message may be accepted by a user-input acceptance transmitted to the server. The system may determine temporary validation authorization if it is determined that the user accepted the in-vehicle authorization message within a predetermined amount of time following transmission of the signal to the server indicating that the processor was installed. Once authorized, the system may initialize to allow for assembly line testing. The temporary validation authorization initializes the vehicle system for temporary communication with the server while on a vehicle manufacturing assembly line for testing to ensure a quality product.

  • Patent number: 8897955
    Abstract: A system for a vehicle includes a conversion efficiency module, a threshold determination module, and a catalyst fault indication module. The conversion efficiency module generates an ozone conversion efficiency of a catalyst that converts ozone into oxygen based on a first amount of ozone in air measured upstream of the catalyst and a second amount of ozone in air measured downstream of the catalyst. The threshold determination module generates an efficiency threshold based on ambient humidity. The catalyst fault indication module selectively indicates that a fault is present in the catalyst when the ozone conversion efficiency is less than the efficiency threshold.

  • Patent number: 8897984
    Abstract: The object of the present invention is to provide a braking force generator capable of preventing a braking force from varying, even if an ON signal of an IG switch is not transmitted. The braking force generator includes a hydraulic pressure generation unit that becomes in an operation state according to an ON state of the IG switch of a vehicle or an opening and closing operation of an opening and closing member of the vehicle and generates a braking force according to an electrical signal based on an operation amount of a driver, and a conditional stop unit that puts the hydraulic pressure generation unit in an operation stop state if an OFF state of the IG switch continues for a predetermined time after the hydraulic pressure generation unit becomes in the operation state according to the opening and closing operation of the opening and closing member.

  • Patent number: 8892298
    Abstract: A method for detecting a wear condition of a tire utilizes tread pattern elements included on the tire. The elements are adapted to generate first and second acoustic footprint noises (BEA1, BEA2), with one of the first and second acoustic footprint noises being characteristic of the wear condition of the tire. According to the method, a parent frequency spectrum, which is capable of forming a frequency spectrum of one of the first and second acoustic footprint noises, and a child frequency spectrum, which is capable of forming a frequency spectrum of the other of the first and second acoustic footprint noises, are selected from a frequency spectrum of an acoustic signal acquired from the tire. Two detection confidence indices are determined. If each detection confidence index meets a predetermined condition, a warning is emitted indicating that tire wear has been detected.

    Abstract: Systems and methods for internal orifice characterization in an evaporative leak check module are disclosed. In one example approach, a method comprises operating a pump to draw air from an emission control system through an orifice to obtain a reference pressure, and indicating a leak in response to pressure in the emission control system remaining above a threshold pressure while operating the pump to decrease pressure in the emission control system, where the threshold pressure is based on a coded indication and the reference pressure.

  • Patent number: 8886395
    Abstract: A dynamic slip angle estimation system and method uses measured vehicle acceleration and yaw rate parameters in estimating a tire slip angle. From load sensor(s) mounted to the vehicle tire, a tire static load estimation is made and a tire slip angle is calculated at low frequency. The vehicle center of gravity longitudinal position and yaw moment of inertia is estimated from the static load on the vehicle tires. An observer calculates tire axle forces based on the vehicle acceleration and yaw rate. From the tire axle force estimations, the vehicle moment of inertia and vehicle center of gravity longitudinal position estimate and a low frequency direct measurement of the tire slip angle, a dynamic tire slip angle calculation is made.

  • Patent number: 8880287
    Abstract: A system and method for determining whether a vehicle driver is holding a steering wheel of the vehicle. The vehicle will include an electric power steering (EPS) system and may include an active front steering (AFS) system. The vehicle may further include autonomous or semi-autonomous driving features or safety features, such as Lane Centering Control (LCC) or Lane Keeping Assist (LKA). The system monitors steering torque and steering angle signals, determines a resonant frequency of oscillation of the steering system from the measured data, and compares the resonant frequency to a known natural frequency of the steering system. If the resonant frequency is lower than the known natural frequency, then the system knows that the vehicle driver is holding the steering wheel. A measured steering torque greater than a threshold value is also taken as an immediate indication of the driver holding the steering wheel.
