摘要:
A driver of a vehicle is alerted if an air passage from an air source to a battery becomes blocked. The determination as to whether the air passage is blocked may be based on the temperature of the battery, the airflow through the air passage, and the power to a fan used to move air through the air passage.

A vehicle includes a first disconnect disposed between a prime mover of the vehicle and a certain one of the vehicle drive wheels. The first disconnect is operable to connect and disconnect the prime mover to and from the certain one of the drive wheels. A second disconnect is disposed between the powertrain and the certain one of the drive wheels, and is operable to connect and disconnect the certain one of the drive wheels to and from the powertrain when the first disconnect is engaged. A control system and method are configured to control operation of at least the first and second disconnects. Through selective control of the disconnects, the system can be automatically placed in a four-wheel-drive mode based on predetermined criteria, or the desirability of the four-wheel-drive mode can be indicated to the vehicle operator in a passive version of the control system and method.

摘要:
A system and method is provided for indicating an efficiency level of energy usage by an automotive vehicle to a passenger in the vehicle. The system includes a computer-readable storage medium, a controller, an interior-lighting system, and a display unit. The controller processes energy usage signals to obtain the given operating mode of the vehicle as well as indications of energy usage amounts that the passenger can control. The controller determines the efficiency level of energy usage by the vehicle based on the energy usage amounts and the given operating mode. The interior-lighting system illuminates at least a portion of the passenger compartment with ambient light having defined characteristics including a luminance and a color, the ambient light indicating the efficiency level. The display unit displays a graphical representation of the efficiency level.

A system and method is provided for electrostatic air filtering in automotive vehicles, such as electric and hybrid electric vehicles. The system includes an electrical distribution system and an electrostatic filtering system having discharge electrodes and an accumulation electrode. The distribution system is in high-voltage electrical communication with the filtering system as well as an electric motor and a high-voltage energy storage device in the vehicle. In operation, the distribution system distributes high-voltage electric power to the filtering system. The filtering system receives the high-voltage electric power to generate a high-voltage electrostatic potential between the accumulation electrode and the discharge electrodes to remove particulates from air flowing through a region of the electrostatic filtering system.

An automotive vehicle may include one or more controllers, a braking system and an electric machine. The one or more controllers may be configured to determine whether the vehicle is about to roll over. The braking system may be configured to apply a braking torque for a time period, under the command of the one or more controllers, to a front traction wheel to cause the front traction wheel to skid or slide relative to a road if the vehicle is about to roll over. The electric machine may be configured to generate a propulsion torque, under the command of the one or more controllers, during the time period.
摘要:
A pedestrian warning or alert system and method are disclosed. The warning system is mounted on an electric vehicle. The warning system includes a front speaker system, a rear speaker system, a front pedestrian detector, a rear pedestrian detector, and an electronic control unit (ECU) electronically coupled to the front speaker system, the rear speaker system, the front pedestrian detector, and the rear pedestrian detector. The ECU commands the front speaker system to emit a warning sound based on the front pedestrian detector detecting a pedestrian-shaped object and commands the rear speaker system to emit a warning sound based on the rear pedestrian detector detecting a pedestrian-shaped object. The ECU is coupled to a microphone, the signal of which is used to estimate an ambient noise level. The intensity and frequency of the warning sound commanded from the front and/or rear speaker system is based on the ambient noise level.

A method for increasing fuel economy of a vehicle such as a plug-in hybrid electric vehicle (PHEV) having an engine and a battery each configured to supply power to propel the vehicle includes supplying power from the battery and operating the engine below peak efficiency to supply from the engine only the difference in power between a demanded power and the power which the battery can deliver when the demanded power exceeds the power which the battery can deliver.
