Patent number: 11904686Abstract: In general, the subject matter described in this disclosure can be embodied in methods, systems, and program products for performing vehicle control. A computing system determines a difference between a recent rate of change and a historical rate of change of a rotating vehicle shaft of a vehicle during a vehicle race. The computing system determines that the difference between the recent rate of change of the rotating vehicle shaft and the historical rate of change of the rotating vehicle shaft satisfies a criteria for limiting vehicle power, wherein the computing system changes the criteria for limiting vehicle power during the vehicle race. The computing system sends a signal for receipt by a vehicle component of the vehicle, to cause the vehicle component to limit rotation of the rotating vehicle shaft.Type: GrantFiled: April 12, 2021Date of Patent: February 20, 2024Assignee: Davis Intellectual Properties LLCInventor: Shannon R.

Patent number: 11467008Abstract: In general, the subject matter described in this disclosure can be embodied in methods, systems, and program products for receiving an indication that a vehicle has begun accelerating from a stationary state. A computing system sets, in response to having received the indication that the vehicle has begun accelerating from the stationary state, an orientation value generated using a gyroscope to a default orientation value. The computing system repeatedly updates the orientation value generated using the gyroscope, based on changes in gyroscope orientation that occurred after the computing system set the orientation value to the default orientation value. The computing system determines that the updated orientation value satisfies criteria that indicates that the vehicle is likely to encounter or has encountered a dangerous situation. The computing system outputs a signal to cause the vehicle to employ a safety measure.Type: GrantFiled: November 17, 2020Date of Patent: October 11, 2022Assignee: Davis Intellectual Properties LLCInventors: Shannon R.

Patent number: 10207713Abstract: In general, the subject matter described in this specification can be embodied in methods, systems, and program products for performing vehicle traction control. Time intervals between points of rotation of a rotating vehicle output shaft are measured. Indicators of shaft rotation rate are generated using, for each generated indicator, a set of one or more of the time intervals. The generated indicators of shaft rotation rate are used to determine a value indicative of a rate of change of shaft rotation rate. An indicator of a maximum allowable output shaft rotation rate is computed. A current indicator of output shaft rotation rate is determined to exceed the maximum allowable output shaft rotation rate. In response to determining that the current indicator exceeds the maximum allowable output shaft rotation rate, a signal to trigger application of a traction control mechanism is output.Type: GrantFiled: December 5, 2016Date of Patent: February 19, 2019Assignee: Davis Intellectual Properties LLCInventor: Shannon R.

Patent number: 6577944Abstract: There is provided a method for controlling the driving traction of a wheel on a surface to reduce slippage of the wheel on the surface without the need to monitor the rotational speed of the wheel where the wheel is driven by a power unit. A threshold value of maximum acceptable acceleration for the power unit is established. The rotational speed of the power unit is measured for a first selected time interval. The rotational speed of the power unit is measured for a second selected time interval. The difference between the rotational speed of the power unit in the second time interval and the rotational speed of the power unit in the first time interval is determined. The difference between the rotational speed of the power unit in the second and first time intervals are compared with the established threshold value. If the difference in rotational speed of the power unit is greater than the established threshold value, a corrective action is initiated to reduce the rotational speed of the power unit.Type: GrantFiled: April 30, 2001Date of Patent: June 10, 2003Inventor: Shannon R.
