Abstract: Hybrid vehicles and control methods for hybrid vehicles. The vehicles and methods are adapted for use with restricted emissions zones, including zero emission zones. The battery state of charge for a hybrid vehicle is controlled to enable passage through a zero emissions zone without the use of the engine in the zero emissions zone. Multiple approaches to the analysis are highlighted.

Abstract: Methods and systems for hybrid vehicle control. A high-level controller and a low-level controller are provided. The high-level controller uses preview information and a model of the low-level controller to calculate optimized tuning parameters for the low-level controller. The low-level controller uses driver inputs and current operating states to calculate optimized torque split for the hybrid engine.

Abstract: Methods and systems for operating a hybrid vehicle having a first power source that uses a rechargeable battery and a second power source that uses a fuel. Preview information relating to upcoming road and traffic is used to generate a speed reference. A transmission torque reference is calculated using the speed reference and upcoming road information. A predictive power split plan is then determined by optimizing use of the first and second power sources to satisfy the transmission torque reference. At least a first sample of the predictive power split plan is then implemented.
