Abstract
A contact state determination apparatus to be applied to a vehicle includes right and left frame lateral acceleration sensors, a vehicle compartment acceleration sensor, and a contact state determination processor. The contact state determination processor is configured to determine a contact state of the vehicle, based on outputs of the right and left frame lateral acceleration sensors and the vehicle compartment acceleration sensor. The contact state determination processor is configured to determine that the contact state is an oblique contact when: the right and left frame lateral acceleration sensors detect the lateral acceleration rates that are in a same direction and are greater than or equal to a predetermined value; and the longitudinal acceleration rate detected by the vehicle compartment acceleration sensor or an integrated value of the longitudinal acceleration rate is greater than or equal to a predetermined oblique contact determination value.
