A vehicle thermal management system includes a vehicle heat pump system, a battery system coolant loop, a drive train coolant loop, and control electronics. The vehicle heat pump system includes a compressor, a cabin condenser, a cabin evaporator, a cabin blower, and a chiller. The battery system coolant loop is in thermal communication with a battery system and with the chiller and selectively in thermal communication with the drive train coolant loop. The control electronics control the components of the vehicle thermal management system to heat the cabin, cool the cabin, heat the battery system, cool the battery system, and cool the drive train. The control electronics may control the compressor to operate in an efficient mode or a lossy mode in which the compressor generates heat. The control electronics may also control the components of the vehicle thermal management system to precondition the battery.

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.

A vehicle air-conditioning device includes: a first coolant-water circulation path in which coolant water passes through an engine ; a second coolant-water circulation path that is communicated with the first coolant-water circulation path and in which the coolant water passes through a vehicle-cabin radiator; a shutting off mechanism that shuts off, when switched to a shut-off state, the communication between the first coolant-water circulation path and the second coolant-water circulation path; and a refrigeration cycle. The refrigeration cycle has: a compressor for compressing cooling medium; a secondary evaporator in which the cooling medium absorbs heat from the coolant water in the first coolant-water circulation path; a secondary condenser that releases heat of the cooling medium that has absorbed the heat at the secondary evaporator to the coolant water in the second coolant-water circulation path; and a secondary expander that decompresses the cooling medium that has passed through the secondary condenser.
