In one embodiment, an autonomous driving system to autonomously drive an autonomous driving vehicle (ADV) includes one or more processors, a perception module executed by the processors to perceive a driving environment surrounding the ADV, and a planning module executed by the processors to plan a path based on perception data of the driving environment to navigate through the driving environment. The processors are mounted on one or more cold plates coupled to a vehicle cooling system of the ADV, the vehicle cooling system having a first radiator and a first coolant distribution loop coupled to a vehicle engine of the ADV to provide liquid cooling to the vehicle engine. The cold plates are coupled to the first radiator via a second coolant distribution loop to receive a portion of the coolant from the first radiator to extract heat from the cold plates.

An air conditioning system for a motor vehicle. The air conditioning system includes a refrigerant circuit divided into a high-pressure region and a low-pressure region, first and second internal heat exchangers arranged in the high-pressure and low-pressure regions, an external heat exchanger arranged in the refrigerant circuit, a condenser arranged in the high-pressure region, and an evaporator that, in a first operating mode, thermally couples the low-pressure region to the air conditioning air and, in a second operating mode, is arranged outside the refrigerant circuit.

An indoor heating line is arranged to pass through a heater core for a coolant heater and indoor air conditioning, and is provided with a first pump so that coolant can flow. A battery heating line is branched from a downstream point of the heater core and connected to an upstream point of the coolant heater after passing through a battery heat exchange part for temperature-raising a high voltage battery, where the battery heating line includes a first heat exchange flow passage that connects a downstream point of the heater core to a first side of the battery heat exchange part, and a second heat exchange flow passage that connects a second side thereof and an upstream point of the coolant heater, where the first heat exchange flow passage and the second heat exchange flow passage are configured to mutually exchange heat.

A thermal management system includes a primary system and a secondary system. The primary system includes a primary refrigerant system and a primary coolant system. The primary system includes a first heat exchanger having a first heat exchange portion and a second heat exchange portion. The secondary system includes a secondary refrigerant system and a secondary coolant system. The secondary system includes a third heat exchanger having a third heat exchange portion and a fourth heat exchange portion. The thermal management system includes a battery heat exchange assembly. In a battery rapid heat dissipation mode, the battery heat exchange assembly is communicated with the second heat exchange portion and the fourth heat exchange portion. Coolant flowing through the second heat exchange portion and the fourth heat exchange portion can quickly dissipate the heat of the battery. A control method of the thermal management system is also disclosed.

Presented are joint active thermal management (JATM) systems with heat exchanger storage of surplus refrigerant, methods for making/operating such systems, and vehicles equipped with such systems. A JATM system includes a coolant loop that fluidly connects to a vehicle battery system for pumping thereto coolant, an oil loop thermally coupled to the coolant loop and fluidly connected to a vehicle powertrain system for pumping thereto oil, and a refrigerant loop thermally coupled to the coolant loop and operable to circulate refrigerant for heating/cooling a passenger compartment. An electronic controller determines if a current amount of refrigerant in the refrigerant loop exceeds a calibrated threshold for the current operating mode of the JATM system. If so, the controller determines if one of the refrigerant loop's heat exchangers is available to store excess refrigerant. If the heat exchanger is available, the refrigerant loop stores excess refrigerant in the available refrigerant heat exchanger.

Secondary loop air conditioning and heat pump systems include a reservoir with a capsule holding a phase change material.

A modular cooling system for a vehicle including a base module having a refrigerant compressor, a high-pressure section having a direct or indirect condenser or gas cooler, and a low-pressure section having an evaporator and a chiller having chiller expansion elements connected upstream. The low-pressure section is connected via a heat pump expansion element to the high-pressure section. A first supplementary module has a heating branch having a heat pump heat exchanger, which is connectable via a first reheating branch having a valve element to the direct or indirect condenser or gas cooler, and a heat pump recirculation branch having a blockable valve element for connecting the direct or indirect condenser or gas cooler to the low-pressure section.
