环境温度传感器是整车重要的感知元器件，常布置于前保格栅、舱内导流板上。随着新能源汽车产业的快速发展，为减少风阻以提高新能源汽车续航里程，前保格栅开口面积变小，导致新鲜空气量减少，从而对环境温度传感器的布置要求显著提高。本文统计了市面上主流车型传感器 YZ 向相对冷凝器的位置，分析了某新能源车型在项目阶段环境温度传感器探测温度较高问题的根本原因，探讨了 X 向传感器到冷凝器距离与传感器至格栅开口距离的比值对传感器测温精度的影响，最终形成一套环境温度传感器的定量评价体系和方法，有效提高了新能源车型环境温度传感器布置的可靠性。

The outside air temperature sensor is a core sensing component of complete vehicles, which is generally arranged on the front bumper grille and cabin deflector. With the rapid development of new energy vehicles, front bumper grilles are designed with smaller opening areas to reduce aerodynamic drag and improve vehicle cruising range, which reduces the intake of fresh ambient air and significantly raises the layout requirements for outside air temperature sensors. This paper conducts statistical analysis on the relative YZ-direction positional relationship between the outside air temperature sensor and the condenser of mass-produced vehicle models. It analyzes the root cause of abnormally high temperature detection of the outside air temperature sensor during the development phase of a specific new energy vehicle model, and explores the influence of the ratio of the sensor's X-direction distance to the condenser and the grille opening size on sensor detection temperature. Finally, a complete quantitative evaluation system and method for the layout of vehicle outside air temperature sensors is established, which effectively improves the layout reliability of outside air temperature sensors in new energy vehicles.
