To investigate the mechanism of vehicle cabin temperature on driver cognitive ability, a vehicle simulation driving platform was built. The driver's physiological parameters, psychological feelings, and cognitive ability were investigated at different cabin temperatures (20 ℃, 23 ℃, 26 ℃, and 30 ℃). The results showed that the cognitive ability of the driver decreased with an increase in cabin temperature. Heart rate increased significantly, and the thermal sensation, thermal comfort, and brain load scores increased; the environmental acceptability, job satisfaction, and job willingness scores decreased. At 20 ℃, the completion time of the cognitive ability test was the shortest, the number of errors was the smallest, and drivers maintained high cognitive ability. At 23 ℃, the driver’s subjective thermal comfort was the best. When the vehicle cabin temperature exceeded 26 ℃, drivers began sweating on their palms, forehead, and back. Therefore, for better cognitive performance and thermal comfort, the vehicle cabin temperature should be maintained at 20–23 ℃. These research results can provide a reference for temperature standards in vehicle cabin design for safe driving.
