A drive control system of a vehicle includes a vehicle speed module configured to determine whether the vehicle is moving and set a state of a signal based on the determination. A shift control module is configured to shift a transmission of the vehicle based on a signal from a range selector. Independently of the signal from the range selector, the shift control module is configured to selectively shift the transmission of the vehicle based on a signal from a combination park and ignition switch and the signal from the vehicle speed module. An ignition control module is configured to selectively shut down an engine of the vehicle based on the signal from the combination park and ignition switch and the signal from the vehicle speed module.

Systems and methods for controlling a transmission and an engine with a combination park and ignition switch

A torque request module is configured to, while a vehicle speed is greater than a predetermined speed, decrease a torque request in response to a first signal from a start/stop switch being in a first state continuously for greater than a first predetermined period and less than a second predetermined period. A control module is configured to, as the torque request decreases, decrease torque output of at least one of an engine and an electric motor. A light control module is configured to: selectively turn exterior hazard lights on and off in response to a second signal from a hazard light switch being in a first state; and selectively turn the exterior hazard lights on and off in response to the first signal from the start/stop switch being in the first state continuously for greater than the first predetermined period.

Systems and methods for controlling an engine and hazard lights based on start/stop switch actuation

Methods and systems are provided for an extended secure idle (SI) for a mobile platform. The SI may be entered and exited responsive to a variety of SI entry and SI exit conditions. SI entry and exit conditions include receiving key fob data from a key fob authenticated with the mobile platform. In addition, various predetermined safeguard conditions for scenarios to monitor may be designated a priori. The described system and method will continually check that the predetermined safeguard conditions are not violated during an extended SI.
