发明名称 ON-VEHICLE DEVICE AND ACCELERATION CORRECTION METHOD
摘要 PROBLEM TO BE SOLVED: To provide an on-vehicle device capable of automatically performing 0 point correction of acceleration even after being attached to a vehicle.SOLUTION: A CPU 10 acquires GPS position information from a GPS receiver 22, and discriminates whether or not a vehicle 5 is at a horizontal location (location of 0G) registered in an EEPROM 12 (S11). When it is not at the horizontal location, the CPU 10 repeats processing in a step 11, and waits for it to move to the registered horizontal location. On the other hand, when it is at the horizontal location, the CPU 10 performs 0 point correction of a G sensor 24, and updates a correction value registered in a memory built in the G sensor 24 or a memory built in the CPU 10 (S12).
