The invention relates to the technical field of positioning, in particular to an inertial sensor device and a vehicle, and the device comprises a first type inertial sensor and N second type inertial sensors which are used for detecting the attitude of target equipment to obtain initial navigation parameter data; the measurement precision of the first type inertial sensor is higher than that of the second type inertial sensor; the control chip is used for respectively acquiring initial navigation parameter data detected by the first type of inertial sensor and the N second type of inertial sensors according to the chip selection signal so as to correspondingly obtain a group of first initial navigation parameter data and N groups of second initial navigation parameter data; the control chip is also used for fusing the first initial navigation parameter data and the N groups of second initial navigation parameter data to obtain target navigation parameter data. Therefore, the problems of high IMU cost, low navigation precision and the like in the prior art can be effectively solved.
