A touch circuit device for a vehicle comprises an analog front-end circuit, a first memory, a second memory, a micro-control unit and an electrostatic discharge protector. The analog front-end circuit is provided with an electrostatic discharge detector which is used for detecting the automotive touch circuit device and outputting a detection result signal; the first memory stores a control parameter with a first debugging code, and correspondingly generates a first debugging signal according to the first debugging code; the second memory stores the touch data with a second debugging code, and correspondingly generates a second debugging signal according to the second debugging code; the micro-control unit generates a notification signal according to the control parameter and the touch data; when the detection result signal shows that no electrostatic discharge interference exists, the electrostatic discharge protector allows the notification signal to be output, and when the detection result signal shows that the electrostatic discharge interference exists and the debugging result represented by at least one of the first debugging signal and the second debugging signal is wrong, the electrostatic discharge protector forbids the notification signal to be output.

    一种车用触控电路装置,包括:一模拟前端电路、一第一储存器、一第二储存器、一微控制单元及一静电放电保护器。模拟前端电路具有一静电放电检测器,用以检测车用触控电路装置并输出一检测结果讯号;第一储存器储存控制参数具有一第一侦错码,依第一侦错码对应产生一第一侦错讯号;第二储存器储存触控数据具有一第二侦错码,依第二侦错码对应产生一第二侦错讯号;微控制单元依据控制参数及该触控数据产生一通知讯号;当检测结果讯号显示无静电放电干扰,静电放电保护器允许通知讯号输出,当检测结果讯号显示有静电放电干扰,且第一侦错讯号及第二侦错讯号至少其中之一所代表的侦错结果为错误时,静电放电保护器禁止该通知讯号输出。
