Circuit for controlling voltage in a tire-based unit of tire parameter sensing system and associated method
Abstract:
A circuit (14) for use in a tire (16) of a vehicle (10) having a tire parameter sensing system (12) includes a battery (60) for supplying electrical energy. The battery (60) has an equivalent series resistance (64) that varies inversely with temperature. The circuit (14) further includes a current control device (90) that is responsive to at least one of an output voltage of the battery and temperature for adjusting a current draw from the battery (60) to insure a predetermined minimum output voltage from the battery (60).
Abstract(Chinese):

一种用于具有轮胎参数检测系统（12）的车辆（10）的轮胎（16）的电路（14）包括用于提供电能的电池（60）。 电池（60）具有与温度成反比变化的等效串联电阻（64）。 电路（14）还包括对电池的输出电压和温度中的至少一个进行响应的电流控制装置（90），用于调节来自电池（60）的电流消耗，以确保来自电池 电池（60）。
