  • Patent number: 10926723
    Abstract: A system and method performed by a sensor testing apparatus of a vehicle are provided for determining when certain event conditions are true. The event conditions comprise detecting an occurrence of a predefined event that impacts a sensor of the vehicle. After the predefined event is detected, a test is performed to determine whether the sensor is outputting sensor values within sensor specification values. When the event conditions are true, the method includes testing the sensor relative to a reference to determine when the sensor is operating within reference criteria to produce a positive reference testing result. When the reference testing result is positive, the method directs the vehicle to return to normal operation, and otherwise directs the vehicle to be serviced.

  • Patent number: 9925842
    Abstract: A damper system and method for a vehicle includes a shock absorber and a damper module. The shock absorber includes a plurality of digital valves. The shock absorber is operable at one of multiple damping states based on a valve state of the digital valves. The damper module is coupled to each of the digital valves and controls each of the digital valves to a desired state based on a damper setting. The damper module determines a target damping state, where the target state is one of the multiple damping states. The damper module performs a switch operation to control the valve state of the plurality of digital valves to a given desired state when the target damping state is different from a present damping state.

  • Patent number: 9902311
    Abstract: A control system of a self-driving vehicle (SDV) can process sensor data from a sensor system of the SDV to autonomously control acceleration, steering, and braking systems of the SDV along a current route. Based on the current route, the control system can dynamically determine a set of immediate actions to be performed by the SDV. Based on the set of immediate actions, the control system can generate a set of intention outputs on a lighting strip of the SDV, the set of intention outputs indicating the set of immediate actions prior to the SDV executing the set of immediate actions.

  • Patent number: 9883371
    Abstract: An anomaly detection system is provided in connection with a transport service. The anomaly detection system can construct routine route profiles for individual users of the transport service using historical route data. The anomaly detection system can monitor a current route traveled by a user. The anomaly detection system can further identify a matching routine route profile of the respective user. The anomaly detection system can utilize the matching routine route profile to identify a probable anomaly in the current route. In response to detecting the probable anomaly, the anomaly detection system can enable a safety protocol to perform a number of actions.

  • Patent number: 9836901
    Abstract: A method of managing student arrival and student dismissal is executed within a remote server as the remote server is communicably coupled with at least one automobile identification (AI) device. The AI device scans an incoming vehicle in order to identify at least one authorized profile. The authorized profile is assigned to a student profile and recognize as one of the driver profiles within the remote server. Upon validation of the authorized profile, the remote server generates an updated instruction that includes at least one student management instruction and at least one additional instruction that are accessed and defined by parent profiles or faculty profiles. Then the updated instruction is sent from the remote server to a selected computing device so that the student arrival and student dismissal can be processed.

  • Patent number: 9831922
    Abstract: A system for determining tread wear of a tire includes a first wireless communication chip located at an inner surface of the tire and a second wireless communication chip located at an outer surface of the tire. The second chip resides in a slot extending through a housing located in a groove in a tread of the tire. The second chip moves in the slot toward the bottom of the groove in response to the tread wear. Methodology entails transmitting a first signal from a first chip, receiving the first signal at the second chip, transmitting a second signal from the second chip in response to receipt of the first signal, receiving the second signal at the first chip, computing a time delay between transmission of the first signal and receipt of the second signal, and determining tread wear of the tire in response to the time delay.

  • Patent number: 9643466
    Abstract: A vehicle includes a suspension corner connecting the vehicle's road wheel to the vehicle's body and characterized by a ride height at the suspension corner. An actuator at the suspension corner is configured to selectively extend and contract in response to a volume of received pressurized fluid to selectively increase and reduce the ride height. The actuator includes a locking device configured to selectively restrain the piston in a predetermined position and release the piston, and includes an actuation mechanism for activating the device to restrain the piston in the predetermined position. A controller is configured to determine if a change in the ride height is required and to assess if the piston is restrained by the locking device. If the piston is restrained by the locking device and the change in ride height is required, the controller releases the piston via the device and then changes the ride height.
