The invention provides a vehicle position signal acquisition method and device. The method comprises the following steps: acquiring a rotary transformer signal output by a rotary transformer carried by a vehicle; counting an error count value of the rotary transformer signal; judging whether the error count value is greater than a preset first calibration count value or not; when the error count value is greater than the first calibration count value, determining that the vehicle position signal generation strategy is an amplitude correction strategy; and performing amplitude correction processing on the rotary transformer signal based on an amplitude correction strategy to obtain a vehicle position signal. Visibly, the method and the device can improve the acquisition robustness of the vehicle position signal, and effectively prevent the risk that the rotary transformer outputs the rotary transformer signal to be abnormal, thereby providing more stable and safer driving experience for a user.
本申请提供一种车用位置信号获取方法及装置,该方法包括:获取车辆搭载的旋转变压器输出的旋变信号;统计旋变信号的错误计数值;判断错误计数值是否大于预设的第一标定计数值;当错误计数值大于第一标定计数值时,确定车用位置信号生成策略为幅值校正策略;基于幅值校正策略对旋变信号进行幅值校正处理,得到车用位置信号。可见,该方法及装置能够提高车用位置信号的获取鲁棒性,有效防范旋转变压器输出旋变信号存在异常的风险,从而为用户提供更稳定、更安全的驾驶体验。
