The invention discloses a steering angle calculation device which comprises a synchronous angle calculation module, an angle calculation module and a safety verification module. The synchronous angle calculation module executes steering system configuration check, bus angle input signal validity check and RPS signal validity check; the synchronization angle calculation module calculates an external angle correction value, a motor accumulation angle, a motor accumulation angle correction value, external angle synchronization quality characteristics, a reference zero point angle and a motor synchronization angle; the angle calculation module calculates a motor rotation angle based on a reference zero point angle and a motor accumulated angle correction value, and calculates a steering wheel rotation angle and a rack position; the security verification module comprises a calculation verification module and a synchronous verification module; the calculation verification module performs range inspection on the calculated steering wheel angle and the rack position, and when the steering wheel angle or the rack position exceeds a preset range, the angle calculation state is set as an invalid state; the synchronous verification module monitors the preset signal, and when the preset signal does not meet the preset condition, the angle calculation state is set to be an invalid state.

    本发明公开了一种转向角度计算装置,包括同步角度计算模块、角度计算模块和安全性校验模块;所述同步角度计算模块执行转向系统配置检查、总线角度输入信号有效性检查和RPS信号有效性检查;所述同步角度计算模块计算外部角度修正值,计算电机累积角度,计算电机累积角度修正值,计算外部角度同步质量特性,计算参考零点角度,计算电机同步角度;所述角度计算模块基于参考零点角度和电机累积角度修正值计算电机转角,并计算方向盘转角和齿条位置;所述安全性校验模块包括计算校验模块和同步校验模块;所述计算校验模块对计算出的方向盘转角和齿条位置进行范围检查,当方向盘转角或齿条位置超出预设范围时,将角度计算状态设置为无效状态;所述同步校验模块对预设信号进行监控,当预设信号不满足预设条件时,将角度计算状态设置为无效状态。
