System and method for cooling vehicle computing device

摘要

A vehicle computer is programmed to determine an expected thermal load for an autonomous driving compute cluster and a target temperature for the compute cluster under the expected thermal load. Based on a comparison of a current temperature of the compute cluster to an ambient temperature, the vehicle computer is further programmed to operate a switching valve in a first coolant path to open the path to one of a radiator portion and a condenser portion and operate, with the path open to the condenser portion, a pump in the first coolant path and a condenser in a second coolant path at speeds respectively based on at least one of the expected thermal load and the target temperature.

1. A computer-implemented method, the computer having a processor and a memory, the memory storing instructions for the method executable by the processor, the method comprising:
determining an expected thermal load for a vehicle compute cluster and a target temperature for the computer under the expected thermal load; comparing a current temperature of the compute cluster and an ambient temperature; opening, based on the comparison, a switching valve for a first coolant path to one of a radiator portion and a condenser portion, the first coolant path being thermally coupled to the compute cluster; and operating, with the valve open to the condenser portion, a pump in the first coolant path and a compressor in a second coolant path at speeds respectively based on at least one of the expected thermal load and the target temperature.
