Latest Patents

Taina is credited with 1 patent: “Slip Speed Monitoring of a Multi-Speed Planetary Transmission.” The invention describes a multi-speed transmission designed to provide at least eight forward speed ratios using planetary gearsets and selective couplers. One disclosed configuration uses four planetary gearsets and six selective couplers, comprising two clutches and four brakes.

A transmission controller operates the selective couplers and monitors their condition. The patent explains that speed sensors placed on selected rotating components can provide enough information to monitor slip speeds across all the couplers, supporting assessment of transmission health.
