An air conditioning system for a start-stop vehicle employs a compressor with a variable displacement. A controller determines a normal Climate Thermal Load (CTL) value for controlling a variable stroke of the variable displacement compressor. A stop event is detected in response to a speed of the vehicle and the occurrence of a predetermined deceleration. During the stop event, the variable stroke is increased by an amount determined in response to the normal CTL value, the speed of the vehicle, and a measure of the deceleration of the vehicle so that an evaporator temperature within the air conditioning system is allowed to decrease while the vehicle is stopping so that climate comfort can be maintained even while the engine is shut off during the subsequent time that the vehicle is stopped.

Optimized cooling for vehicle with start-stop technology

A method of conserving energy during a heating event wherein a coolant is heated in a cooling system is disclosed. The method includes establishing a first set point temperature for a first point in the cooling system and establishing a second set point temperature lower than the first set point temperature for a second point in the cooling system. Normally, the coolant is maintained at the second set point temperature at the second set point in the cooling system. During the heating event, the second set point temperature is raised to substantially match the first set point temperature to reduce necessary heating of the coolant at the first point.

Switchable radiator bypass valve set point to improve energy efficiency

A method to control a hydraulic pump of a vehicle, the pump coupled to at least a power steering system and a power braking system is provided. The method comprises measuring steering and braking information using a brake sensor and a steering sensor; and adjusting output of said hydraulic pump based on measured information from said sensors.
