  • Patent number: 10023103
    Abstract: A bank angle of a vehicle can be accurately calculated using yaw axis data and roll axis data, and based on the calculated bank angle, vehicle illumination optics can be controlled to maintain a pattern of distributed light from the illumination optics to be generally horizontal. The calculated bank angle may be zeroed when the yaw axis data equals zero. The improved pattern of distributed light from the illumination optics illuminates a more natural field of view for the vehicle driver during a bank. In some embodiments, the vehicle illumination optics can include a primary illumination group and a plurality of side illumination groups.

    Abstract: A method is disclosed for determining the cost of operating a vehicle over a defined period of time. The method proceeds by establishing, on a database, a schedule of anticipated future repairs for a plurality of vehicle types, the repair schedule including the cost of the repairs and the approximate mileage at which the anticipated future repair(s) are expected to become necessary. A processor, in communication with the database, receives information identifying a particular of vehicle, and the present mileage associated with that particular vehicle. Using the vehicle type information, the vehicle's present mileage information and the repair schedule, the processor then computes the approximate total future repair costs for maintaining the vehicle over a defined period of time.

  • Patent number: 8768565
    Abstract: A rental/car-share (RCS) vehicle access and management system and method, in some embodiments, utilizes barcodes, QR codes (or NFC/RFID), GPS, and a mobile app coupled with a wireless network to enable customers to bypass the reservation desk and pickup and drop off reserved RCS vehicles using a mobile phone, tablet or laptop. The QR code, RFID, or NFC communication with the mobile application allows for identification of the vehicle by a mobile application, which, if authorized, can access the vehicle via a temporary access code issued by remote servers. The remote servers and/or mobile application communicates with a control module that plugs into the on-board diagnostics module of the rental/car-share (RCS) vehicle and includes a host processing unit with a processor, an accelerometer, data storage, a GPS with internal GPS antenna; a wireless modem with internal antenna, and CAN bus transceivers connected with the processor, and a USB programmable interface.

  • Patent number: 8755985
    Abstract: A method of monitoring at least one limited-lifetime part. During an identification step (STP1), storage means (40) store a list including a reference for each limited-lifetime part of an engine (3). During an information-search step (STP2), the storage means (40) communicate with a centralized data system (DB) in order to store for each identified part the corresponding maintenance data. During a monitoring step (STP3), the wear of the engine is monitored by using the information stored in the storage means (40).

  • Patent number: 8718893
    Abstract: Disclosed is a method of detecting a failure of a motor of an electric brake booster. The method includes: a) determining whether the electric vehicle brake booster is in the brake pressure control mode or the motor position control mode; b) storing a first position value of the motor for each of predetermined periods when it is determined that the electric vehicle brake booster is in the brake pressure control mode; c) comparing the first position value stored for the last period among the first position values with a second position value of the motor in the motor position control mode when the brake pressure control mode is changed to the motor position control mode; and d) determining that the motor is in a locked state when the first position value and the second position value are substantially identical.

  • Publication number: 20140095015
    Abstract: An indicator of an estimated remaining life of an associated spring device can include at least one sensor and at least one processor. The at least one sensor can be operative to generate a signal having a relation to at least one of a usage condition and an environmental exposure condition of a spring device. The at least one processor can be communicatively coupled with the at least one sensor and programmed to receive signals from the at least one sensor, derive data from the received signals, and determine an estimated remaining life of at least the spring device using the data and an expression modeling a relationship between an estimated remaining life of the spring device and at least one of a usage condition and an environmental exposure condition. A gas spring and indicator assembly, a suspension system and a method are also included.

  • Patent number: 8670895
    Abstract: A vehicle diagnostic tool configured to interface with a removable memory device. The removable memory device is configured to store information about the vehicle such as, for example, the maintenance history of the vehicle and notes or special instructions from one or more mechanics having performed the maintenance. The memory device, once disengaged from the diagnostic tool, is given to the vehicle's owner for safekeeping and may be incorporated in a key, fob or other device that the owner would often have available when operating the vehicle. Also, a method of collecting and storing vehicle data is also provided.

  • Publication number: 20140052328
    Abstract: There is provided a method of predicting defects likely to occur in a vehicle over a predetermined period. The method includes receiving vehicle characteristic data regarding a vehicle under consideration, and comparing the received vehicle characteristic data with a defect database. The defect database includes information related to defects that have occurred in different vehicles and the mileage at which such defects occurred. The method additionally includes identifying defects that occurred in vehicles corresponding to use vehicle under consideration, and the mileage at which such defects occurred. Detects which fail to satisfy minimum count requirements are then filtered out, and the defects are then sorted in order of the highest defect count.

  • Patent number: 8634985
    Abstract: A method of detecting an in-range failure of a brake pedal position sensor includes calculating the difference between a minimum position and a maximum position of the brake pedal position sensor. The calculated difference is weighted to define a fast test weighted input value and/or a full test weighted input value. A cumulative test result value is incremented by the fast test weighted input value and/or the full test weighted input value. The cumulative test result value is filtered to define a moving average of the cumulative test result value after each incremented occurrence. The moving average of the cumulative test result value is tracked to determine if the brake pedal position sensor is functioning properly.
