The utility model relates to a vertical acceleration and temperature signal pickup assembly for vehicles, which comprises a sensor module, a signal acquisition unit, a signal pretreatment unit, a data packet packaging unit, a parameter storage unit, a self-diagnosis system and a data communication circuit. The sensor module is composed of a vertical acceleration sensor, a temperature data sensor and an SPI interface circuit, and is connected with the signal acquisition unit. The signal acquisition unit is connected with the data packet packaging unit through the signal pretreatment unit. The data packet packaging unit is connected with the data communication circuit. The beneficial effects are that: the vertical acceleration and temperature signal pickup assembly not only has the acquisition function of vertical acceleration and temperature signals, but also has the pretreatment function, and directly communicates with an ECU control system of a damper through a CAN bus interface; and has characteristics of high precision, fast dynamic response speed, low power dissipation, small size, etc.
