Abstract: Embodiments of the invention provide a controller for a hybrid electric vehicle (HEV) having an engine and an electric machine, the controller being configured upon start-up to control an electric machine to provide torque to drive a vehicle with an engine off if a state of charge (SoC) of an energy storage device is above an EV-start SoC threshold and to start an engine if a SoC of an energy storage device is below the EV-start SoC threshold, wherein the EV-start SoC threshold is determined to be one selected from amongst a value sufficient to allow a vehicle to travel a prescribed distance before a SoC falls below a SoC minimum level at which an engine is started and a value sufficient to allow a vehicle to operate for a prescribed time period before a SoC falls below the SoC minimum level.

Abstract: A tire pressure monitoring system (12) for a vehicle (10) includes a speed sensor (38) generating a speed signal indicative of vehicle speed, a timer (44) generating a time signal, a warning status memory (26) having warning statuses therein. The system further includes a plurality of rolling tires in respective rolling location. The plurality of rolling tires (14a), (14b), (14c) and (14d) have respective rolling transmitters (16a), (16b), (16c) and (16d). An auxiliary tire (14f) in an auxiliary location has an auxiliary transmitter (16f) that generates an auxiliary sensor transmission signal. A controller (22) is coupled to the rolling transmitters, the spare tire transmitter and the warning status memory (26). The controller (22) receives the auxiliary sensor transmission signal.
