Abstract
A vehicle collision detection system that includes: a controller that actuates an occupant restraint device in a case in which a collision between a vehicle and an object has been predicted by a collision prediction section, a collision mode has been determined to be an underride mode by a determination section, the object has been determined to be another vehicle by the determination section, and an acceleration detected by a first acceleration sensor is at or above an underride-mode-actuation determination threshold that is lower than a normal-actuation determination threshold for the occupant restraint device.
Claims9
A vehicle collision detection system comprising:
- a determination section that, in a case in which a collision between an object and a vehicle installed with an occupant restraint device has been predicted by a collision prediction section, determines whether or not a collision mode between the vehicle and the object is an underride mode based on an acceleration detected by a first acceleration sensor provided in a vehicle cabin and an acceleration detected by a second acceleration sensor provided further toward a vehicle front than the vehicle cabin, and also determines whether or not the object is another vehicle;
- and
- a controller that actuates the occupant restraint device in a case in which a collision between the vehicle and an object has been predicted by the collision prediction section, the collision mode has been determined to be the underride mode by the determination section, the object has been determined to be another vehicle by the determination section, and the acceleration detected by the first acceleration sensor is at or above an underride-mode-actuation determination threshold that is lower than a normal-actuation determination threshold for the occupant restraint device.
A non-transitory recording medium storing a program executable by a computer to perform vehicle collision detection processing, the vehicle collision detection processing comprising:
- in a case in which a collision between an object and a vehicle installed with an occupant restraint device has been predicted, determining whether or not a collision mode between the vehicle and the object is an underride mode based on an acceleration detected by a first acceleration sensor provided in a vehicle cabin and an acceleration detected by a second acceleration sensor provided further toward a vehicle front than the vehicle cabin, and also determining whether or not the object is another vehicle;
- and
- actuating the occupant restraint device in a case in which a collision between the vehicle and an object has been predicted, the collision mode has been determined to be the underride mode, the object has been determined to be another vehicle, and the acceleration detected by the first acceleration sensor is at or above an underride-mode-actuation determination threshold that is lower than a normal-actuation determination threshold for the occupant restraint device.
