Abstract: A controller for a hybrid vehicle controls a first motor generator and a second motor generator such that electric power input to a battery does not exceed an input upper limit value and electric power output from the battery does not exceed an output upper limit value. The controller executes motoring to rotate an output shaft using the first motor generator with combustion operation of an engine stopped, thereby causing a braking force generated by friction of the engine to act on a driven wheel. The controller executes a valve-opening limitation process that limits an increase in a throttle open degree in correspondence with the input upper limit value upon issuance of an increase request for the throttle open degree that is not based on an operation of requesting a change in the braking force performed by a driver during the execution of the motoring.

In one implementation, the controller is configured to engage compression immediately upon detecting that the vehicle is decelerating. One or more kits can be used to retrofit existing vehicles to operate the respective air conditioning systems principally on waste energy.

Abstract: Implementations of the present invention include systems, methods, and apparatus for improving the fuel efficiency (mpg/kpl) of a motor vehicle during those times when the vehicle air conditioning system is operating. Whenever the driver takes his foot off the gas, or the vehicle engine is otherwise caused to decelerate, the refrigerant compressor clutch engages, allowing the compressor to operate on previously-imparted vehicle waste energy (e.g., imparted by the engine, or by downhill travel.) When the refrigerant pressure reaches a pre-set maximum value, the clutch is deactivated, and the compressor stops. When the refrigerant pressure reaches a pre-set minimum level, the clutch is activated regardless of the existence of vehicle waste energy. When the refrigerant pressure reaches another pre-set level between the aforementioned maximum and minimum levels, in the absence of any vehicle waste energy, the clutch is again deactivated and the compressor stops.

Abstract: When an actual output power level of an engine is greater than a preset engine power demand due to the higher density of intake air in a cold environment, the control procedure of the invention controls a motor to raise a rotation speed of the engine with a throttle opening TH kept at a current level, so as to make the actual output power level of the engine substantially equal to the engine power demand (this is attained by, for example, a change of a target drive point from a point A to a point B). This arrangement effectively restrains a battery from being charged with an unexpectedly large electric power and prevents frequent changeover between the stop and the start of the engine with a significant variation in current state of charge (SOC) of the battery.
