摘要： A system for discharging or charging a capacitor of a hybrid vehicle according to the present disclosure includes a target state of charge (SOC) module and a capacitor charge/discharge module. The target SOC module determines a target state of charge of the capacitor based on a speed of the vehicle. The capacitor charge/discharge module determines whether a state of charge of a capacitor is greater than a target state of charge. The capacitor charge/discharge module dissipates power from the capacitor to at least one of a battery of the vehicle and an electrical load of the vehicle when the state of charge of the capacitor is greater than the target state of charge.

摘要： A vehicle has a front grille, engine, engine compartment, power storage device, temperature sensor, shutter, heater and controller. The device can be electrically charged from an external power supply. The temperature sensor detects engine coolant temperature. The shutter is disposed in a transfer pathway of air drawn into the engine compartment via the front grille, and is switched between closed and open states. The heater is able to generate heat when receiving the electric power, raising the coolant temperature. The controller starts the engine when the coolant temperature is lower than a startup threshold value, drives the heater when the coolant temperature is lower than a first threshold value equal to or higher than the startup threshold value, until the coolant temperature becomes equal to or higher than the first threshold value, and drives the shutter to place the shutter in the closed state while the heater is driven.

摘要： Described herein is a device and method for current flow control for dual battery vehicle architecture. The dual battery vehicle architecture includes a second energy source that is used to support electrical loads, such as radio and navigation systems, during re-cranking in stop-start situations. A quasi-diode device is configured to effectively split a main battery and starter circuit from the rest of the vehicle electrical system including the second energy source. The quasi-diode device includes a plurality of field effect transistors (FET) that conducts current in both directions between the main battery and starter circuit and the rest of the vehicle electrical system when the FETs are turned on and conducts current only from the main battery and starter circuit to the rest of the vehicle electrical system when the FETs are turned off, i.e. when re-cranking is occurring during a start-stop situation.

摘要： A control system for a hybrid electric vehicle comprises a transmission system configured to drive wheels, an engine power subsystem connected to the transmission system, a motor power subsystem connected to the transmission system and a control module. When vehicle's electrical power is on, the control module is configured to control operating mode of the hybrid electric vehicle through the engine power subsystem and the motor power subsystem. The operating mode comprises HEV-eco mode and HEV-s mode. When the hybrid electric vehicle operates in HEV-eco and the hybrid electric vehicle operates at low power or when the hybrid electric vehicle operates in HEV-s mode and when the vehicle speed is zero, the control module enables the hybrid electric vehicle to operate by idle start-stop strategy.
