A vehicle includes an electric machine and a controller. The controller is programmed to, in response to releasing an accelerator pedal during a first driving scenario that is based on a first set of navigation data, increase regenerative braking torque of the electric machine to a first value. The controller is further programmed to, in response to releasing the accelerator pedal during a second driving scenario that is based on a second set of navigation data, increase the regenerative braking torque of the electric machine to a second value that is less than the first value.

Methods and systems are provided for regulating the temperature of rear axle lubrication oil. In one example, a rear axle coolant system may include a coolant loop with a plurality of valves and sensors, regulating the coolant flow in heat exchange relationship with an exhaust gas heat recovery and storage system to deliver warm coolant to a rear axle heat exchanger to warm the rear axle lubrication oil. The method may regulate the components of the rear axle coolant system through a controller, receiving sensor input from the components of the coolant system.

Fuel-cell thermal management systems and control schemes therefore are disclosed. In one embodiment, the system may include a fuel-cell stack, a heat-exchanger, a thermal battery including a material having a melting temperature of 50-120&#xb0; C., a first coolant loop including the fuel-cell stack and the thermal battery and excluding the heat-exchanger, and a second coolant loop including the fuel-cell stack, the thermal battery, and the heat-exchanger. The first and second coolant loops may be configured to heat and cool the fuel-cell stack, respectively. The system may include a controller or processor configured to direct coolant to transfer heat from the thermal battery to the fuel-cell stack based on a negative heat rejection status of the fuel-cell stack and to transfer heat from the fuel-cell stack to the thermal battery based on a positive heat rejection status of the fuel-cell stack when the thermal battery is below a target temperature.

Methods and systems are provided for adjusting vehicle grille shutters based on a direction of motion of the grille shutters. In one example, a method includes adjusting a motor coupled to the grille shutters based on the direction of motion of the grille shutters, a desired opening of the grille shutters, and vehicle speed. Further, the method may include determining the direction of motion of the grille shutters based on a desired motor position relative to an actual motor position.

A system and methods for inferring a local engine temperature based on various engine conditions input to a dynamic model are disclosed. In the example system provided, an inferential temperature sensor uses a trainable model to estimate a local metal temperature in an exhaust valve bridge of a cylinder head which thereby allows closed loop control of a coolant flow device independent from engine speed, engine state, coolant flow state or system temperature. In response to estimated local metal temperatures, the methods described further allow thermal management of the engine system to be optimized.
