Abstract: An electronic control system controls operation of a vehicle system by selectably controlling the vehicle system using engine start-stop controls in response to one or more engine start-stop conditions being met, controlling the vehicle system using neutral-at-stop controls in response to one or more neutral-at-stop conditions being met, and controlling the vehicle system using cylinder deactivation controls in response to the one or more neutral-at-stop conditions not being met.

Abstract: A vehicle system includes an engine, a transmission including a torque converter, a clutch configured to selectably couple and decouple the torque converter, and a gearset, a selective catalytic reduction (SCR) exhaust aftertreatment system. An electronic control system may be operatively coupled with the engine, the electronically controllable clutch, and the SCR exhaust aftertreatment system. The electronic control system is configured to evaluate whether an SCR catalyst temperature satisfies at least one minimum temperature criterion, in response to the SCR catalyst temperature satisfying the minimum temperature criterion, permit a neutral at stop operation wherein the electronically controllable clutch is controlled to selectably decouple the torque converter and the one or more gears at least in part in response to the vehicle system being in a stopped state, and in response to the SCR catalyst temperature not satisfying the minimum temperature criterion, prevent the neutral at stop operation.
