A vehicle includes a vehicle cooling system for cooling a cabin and a battery system, each having a respective target operating range. The cooling system is configured to select among a cabin-only mode, battery-only mode, or a hybrid cooling mode for cooling the cabin and the battery system. In the hybrid mode, the system determines a desired pressure at an inlet of a compressor corresponding to a suction pressure of the compressor, to avoid cooling interruptions. The system generates a control signal based on the desired suction pressure, and applies the control signal to the compressor. Generating the control signal may include generating a feedforward signal the desired suction pressure, generating a feedback signal based on the suction pressure, or a combination thereof. For example, the use of hybrid mode based on suction pressure allows smoother response to targets with reduced delays in response in meeting the cooling demands.
