The invention relates to a vehicle-mounted sensor signal processing circuit for dynamic wheel load measurement, which comprises an amplifying circuit, a follower circuit and an ADC chip which are connected in sequence, a vehicle-mounted sensor outputs a pair of differential signals, the output of the vehicle-mounted sensor is connected with the amplifying circuit, and the output of the ADC chip is connected with a whole vehicle processor. The amplifying circuit uses a two-channel instrument amplifier. Compared with the prior art, the sensor signal preprocessing circuit for controlling the vehicle chassis is designed, so that reliability and accuracy of data are guaranteed, meanwhile, high universality is achieved, and reference can be provided for signal processing of other vehicle-mounted sensors.

    本发明涉及一种用于动态轮荷测定的车载传感器信号处理电路,包括依次连接的放大电路、跟随器电路与ADC芯片,车载传感器输出一对差分信号,车载传感器的输出连接放大电路,ADC芯片的输出连接整车处理器,放大电路使用两通道的仪表放大器。与现有技术相比,本发明设计了一套用于车辆底盘控制的传感器信号预处理电路,从而保证了数据的可靠准确,同时具备较强的通用性,可为其他车载传感器的信号处理提供参考。
