US 11,897,449 B2 · Hybrid vehicle control units configured for operation continuity

Abstract

A vehicle control system includes a transmission unit, first and second sources, as well as first, second, and third control units. The first control unit controls the transmission unit. The first source inputs energy to the transmission unit. The second source inputs energy to the transmission unit. The second control unit controls the first source. The third control unit controls the second source. The first control unit has a function of continuing an operation when a failure occurs. The second control unit and the third control unit have a common cause failure measure. The function mixes energy from different sources and transmits energy to the driving wheel.
